General Principles of Foundational Sciences

I like all videos & I want to more teach you about this and your lectures is so brilliant

It represents the form of most prevalent diseases nowadays.It's important for the medical-science.

Dr. Ahern is amazing at linking what he's about to teach to previous videos.

So far so good. The videos are easy to follow and I love the questions that pull up at the end of the videos to recall the information. Looking forward on finishing the rest of the modules in biochemistry, including all the other sections.

Hmm slow Understanding Hi Hi Hi how many words for bedrock severs the best player from the bottom line of n mosses ?

The video by Lecturio provides an excellent overview of the electron transport chain and chemiosmosis, two of the most important metabolic processes in the cell. These processes work together to produce ATP, the cell's energy currency. One of the most interesting things about the electron transport chain is that it is a highly efficient way to convert energy from food into ATP. The chain uses the energy from NADH and FADH2, two electron carriers that are produced during glycolysis and the Krebs cycle, to pump protons across the inner mitochondrial membrane. This creates a proton gradient, which is like a dam holding back a reservoir of energy. The ATP synthase enzyme then uses the energy of the proton gradient to drive the synthesis of ATP from ADP and inorganic phosphate. This process is called chemiosmosis. The video does a great job of explaining the complex steps of the electron transport chain and chemiosmosis in a clear and concise way. It also provides helpful animations and diagrams that illustrate the process.

I've reviewed the Video, and while it provides a comprehensive overview, there are a few points that need clarification. "Fatty acid synthesis doesn't occur in the mitochondrion; it occurs in the cytoplasm, sequestered from fatty acid oxidation, simplifying the regulation of the two pathways." Clarification: Fatty acid synthesis indeed occurs in the cytoplasm, separate from fatty acid oxidation that takes place in mitochondria. This separation allows for streamlined regulation, ensuring the balance between synthesis and breakdown. "Fatty acid synthesis is chemically similar to the reverse of oxidation, involving joining, reduction, loss of water, and a final reduction, making it essentially the reverse of oxidation." Clarification: Fatty acid synthesis does indeed involve joining of acetyl and malonyl units, reduction steps, and removal of water, making it similar but not exactly the reverse of oxidation. The subtle differences in the chemical steps are crucial for the controlled synthesis of fatty acids. "The enzyme acetyl-CoA carboxylase is regulated through phosphorylation by AMP-activated protein kinase and allosteric binding of citrate, ensuring the balance between synthesis and cellular energy levels." Clarification: Acetyl-CoA carboxylase, a key enzyme in fatty acid synthesis, is indeed regulated through phosphorylation and allosteric binding of citrate. This regulation allows cells to respond to energy demands, modulating fatty acid production accordingly. "Fatty acid synthesis involves a series of steps catalyzed by the multifunctional enzyme fatty acid synthase, where individual activities within the enzyme complex work together, ensuring efficient fatty acid production." Clarification: Fatty acid synthase, a multi functional enzyme complex, plays a central role in fatty acid synthesis. Its individual activities work in harmony within the complex, allowing for the sequential addition of carbon units and the creation of fatty acids up to 16 carbons in length.

The following are the errors in the information you provided: 00:24 The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. 01:15 The structural formula for lactose is C12H22O11. This means that it is a disaccharide made up of two monosaccharides, glucose and galactose. 01:39 Polysaccharides are polymers of monosaccharides, but they do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure. Here is a corrected version of the information you provided: Carbohydrates are molecules whose name literally means hydrates of carbon. This is because monosaccharides, the simplest carbohydrates, have a ratio of one carbon atom to two hydrogen atoms to one oxygen atom, the same as water. The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. Disaccharides are carbohydrates that are made up of two monosaccharides. They are formed by a glycosidic linkage between the two monosaccharides. Disaccharides have the general formula C12H22O11. Examples of disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose). Polysaccharides are carbohydrates that are made up of many monosaccharides. They are formed by glycosidic linkages between the monosaccharides. Polysaccharides have the general formula (C6H10O5)n, where n is the number of monosaccharides in the polysaccharide. Examples of polysaccharides include cellulose, starch, glycogen, and chitin. Polysaccharides do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure.

Clear explanation, and also the professor answers the questions clearly and fast in the forum !

she is doing very well in explaining the topics and precise.

The lectures are not bad, they have the material, tbey are very well spoken and easy to undersgand. I find some quizz questions to not be relevant, i believe i won't be aske dthese questions on exam. And sometime the material itself feels dry. I am more of a doers, so by solving more complicated questions with the help of a professor would my learning experience much better. But over all not a bad course.

Thank you! I appreciate how you explain this material. Thank you

Great Lecturer..well explained. Every section of lectures are meticulously explained. Clearly understood.

Simple, not over-complicated and understandable, all great signs of an amazing lecture.

ok me gusto mucho esta leccion , gracias por hacer lecturio para estudiar

Muy buena conferencia, haciendo un buen resumen del tema para un mejor entendimiento general

Sublime talk about so many topics,correlating systems, comming from the basics, using only one image, congratulations Dr Raj. Totally recommended and worth to watch over and over.

I like this course because the lecturer explains and present slides in a clear format. The contents of the course are well delivered. I really recommend this course.

It was an excellent Class with essential and new information.

it's very easy and simply explained and I loved it It was very helpful

sooooo sooo good!!! i understoof everything and is amazing that he included everything important about this bacteria! great teacher!

Great material easy to learn good pictures …..thank you so much

I am appreciative that Dr. Ahern took the time to update his lectures. Shows he cares. Thank you!

This lecture was extremely superficial. Serology is not discussed and neither the nuances of treatment of the pregnant patient. Cerebral and ocular forms of toxoplasmosis were also skipped. You need to get a physician specializing in Famliy Medicine to give this leture.

Simply explained. Can't emphasize more how important this is

So useful, and yes the sound is on! It would be nice if you went deeper into the diagnosis

I like the immediate quiz and 'notes' format after each video.

The information is presented in a way that is easy to understand! Thank you ????

very confused and not organized I feel like its too messy and i can't catch the points

really gr8. to the point. fascinating. this whole program is quality cme. _JC

A great summary and introduction to an important but sometimes confusing topic. The questions following the mini lectures sometimes seemed out of sink, covered in a later lecture, etc. For students using this as a key resource, it is essential they understand that using the suggested textbooks and answering all the questions is necessary if preparing of licensing exams, etc.

I like it very much ! This particular lecture is very complex and brilliant way of presenting by a doctor Vincent Racaniello.

Clear and understandable concept with actual molecules shown aswell which is very helpful.

I wish there were more foundational details included. I think Dr. Cornwall presented the material with the expectation that the listener already has a solid foundation in genetics.

Bio means life, chemistry means the composition of matter and energy requirements for life to exist. Chemicals and anyone

I appreciate the approach to clear concepts and road map to the subject matter.

Unfortunately, Dr Cornwall confuses an already confusing topic. Waste of time that i don't have

This subject was amazing to learn, and Georgina makes it easy to understand, so I could say that really loved this course, thank you.

Well structured and comprehensible. Ms Georgina Cornwall makes pleasant pauses between sentences, speaks clearly and explains so that it is easy to follow. The questions afterwards are also very helpful.

I understand that medical genetics is a difficult course to review but improvements are definitely needed in the following areas: 1. State and simplify definitions. Too often i need to refer to Google for a more basic explanation. 2. Please stop assuming basic knowledge is still fresh. I haven't study genetics in 7 years and i have forgotten EVERYTHING! So, along the way and with each new concept please give some foundational information.

I call him the "Bacteria man". One of the best !! His level of knowledge in the course is spectacular. Great !! I don't dislike anything about him I will recommend to my colleagues medical students

This man has made microbiology really easy for me to revise I like him so much because he is knowledgeable and calm. I definitely don't dislike anything about him I will recommend to my colleagues medical students

Prof Kevin Ahern is incredible! Great summary and really well explained!

I am enjoying the lectures. I have two, very minor issues. 1. They are a bit too "granular". Some are so short as to prevent you from digesting the material as it is presented. 2. On several occasions, the questions were not covered in that segment but rather in the next!

It was just what I really needed I love lecturio so much

Topic is not comparing the topics from previous topics in the table form. Then students will remembered

not explned wel as the topic is difficult and you made it a lot much boring

easy and complete explanation for a complex topic, you're the best!

As a retired physician, still professing clinical subjects at a medical school, it is great to have an opportunity to revisit topics last studied in depth in the 1970s! It is presented in clear and digestible aliquots and in a logical sequence by qualified lecturers.

The teaching is basic and does not represent material tested on USMLE exams. The concepts are taught by an instructor unfamiliar with the actual exam. Technically, questions pop up in the middle of a sentence and sometimes before the subject matter tested was mentioned.

well explained lectures well explained lectures well explained lectures well explained lectures

An excellent and detailed description of each phase with emphases on correct language.

so far I have been enjoying the course, would love to go back and continue when I'm not so occupied

All the lectures have been so, so helpful. Thank you so much!

Ms Cornwall presentations hard to understand with no clear imaging and orientation of the slides

Concise and easy to understand content. Thank you Dr.Georgina!

Great review for practicing physicians who have been out of med school for some time.

Kevin is Amazing man, his body language get a lot to his explanation!

Literally worst professor ever, she seems so desoriented and feels like she haven't even prepared the class

on of the best lecture thanks to professor and lecturio also

The lectures are quite informative and clearly presented. It's like I'm attending a class for the very first time since I've taken an extended break from studying microbiology but I am confident that I will do well

It is too simple like introductory biology. We need more advanced molecular biology

I like aging by Ms. Georgina .the data is precise .

Exellent lecture. Thank for teaching me. Enjoy teaching you are best.

Dr. Rcaniello has very good lecture, easy to understand and a pleasure to watch! The tone is calm and the explanation are so detailed and well explained! Thank you!

lack of information no explanation ,its like you are reading headings. and the quiz questions are poorly made.

It's very well explained, but still need to be more detailed. For my parasites exam it is not suffice.

It is clear and well organized so that I could learn the subjects which seemed complicated when the lecturer presented them in university. It also made me interested in microbiology which I didn't even like to learn it. Thank you

excellent explanation of topic very difficult to understand for a med student

Physiology for me was just something that, as Medicine student, I had to study... After Dr. Thad Wilson's courses, actually I'm enjoying it! Very good structure, the tone is calm, very good explanation, funny mnemonics and many useful info that I'm sure will be valuable for my proffesional future! Thank you, Dr. Wilson!!!

The information is organized, highlights what's important. However, I believe that some of the pathways could have been explained a little more. Overall it's very concise and precise

I like it because it because reading about this topic was challenging but these videos bringing it to life makes very exciting, simple and concise. Thumbs up ????. Would definitely recommend

I'm a fan of Dr. Wilson! Everything very well structured, the tone of voice is calm and everything is explained well, in details. Thank you, Dr. Wilson! My goal as a student is to successfully finish the entire Physiology course :)

I really liked and very helpful lectures thank u sir for your explanation

Thank you for this lecture. Very good explanation, excellent structure! Dr. Wilson, you are awesome!!!

Great way to remember the three portions of the ribosome!

I, really, liked ALL of Dr. Cornwall's lectures, but did NOT find time to rate them! I am, still, trying to put it all together because molecular biology is my most difficult subject, but Dr. Cornwall put together much that I knew -- and I am far better off than beforehand! I, definitely, now understand as much as any medical student ought to about molecular biology -- and thus, I am glad that I made notes the whole way, giving me paperwork to re-think all that Dr. Cornwall taught me! Thus, I wish Dr. Cornwall the best and am grateful! :)

So easy and set in an interesting way. Very well covered

Comprehensive up to date information provided concisely by an excellent friendly lecturer

Breaks concepts down easily and love the review questions. Helps solidify learning.

Thank you, Dt. Cornwall, for this chapter!!! It was very useful and finally, with the help of your tips, mnemonic and your awesome teaching style, I could understand the process!

Great lecture, very allegoric, nice and easy to understand. Great didactics and methodology.

Muy claro y conciso con su conferencia, me agrada la manera de abordar el tema.

The lecture series was great over all but I was wondering if there’s an anion gap lecture regarding the calculations needed to identify a widened gap as well as the delta-delta equations. And if so why isn’t it part of the acid-based series?

Really well done! It’s very helpful to recall and reinforce basic concepts.

I have really learned. Before, I was wondering why study, or cram all those pathways and enzymes. How Professor Kevin Ahern explains and bring out concepts, Oh my God so great. He was born a teacher and just polished by learning! He never leaves behind any one, even the slow learners can pick, because once one understands the basic, the necessary complex facts can be understood quite faster! I am now thinking of mastering in Biochemistry, besides my goal of Internal medicine. To be the best Physician, Biochemistry I have understood is one of the vital tools! In my Nursing practice, we lost a 10 yr old male with Liver Cirrhosis from a liver disease, which was diagnosed in early age. Now, I am thinking of a Deficiency of the Transaldolase enzyme!! Ahh save for my little knowledge! Kind regards!

Really a great and elaborate presentation. Thanks Prof. Kevin. Now I no longer struggle in cramming Biochemistry but rather find the subject interesting. I wish I started using your lecture guide early in Medical school, but any way not yet late! Thank you once again.

very new insight to explain macronutrient and fruit for thought

Very good explanation by Dr. Vincent Racaniello. Clear and precise language and can be well understood by laymen. Pretty impressive work. Highly recommended.

Very dense lecture. Maybe a bit too in-depth in some places, but excellent discussion about the importance of carbohydrates and the key enzymes and reactions that underly the process.

Excellent review and explanations of the different vitamins and their various forms and functions.

Really liked Enough chemistry to explain it / not more Shows that she is passonate about the subject

Really love the videos by Proff Elliot, and I love that he explains that concepts are constantly changing but gave us the foundation to build on.

Excellent summary and overview. Read the concept pages for more detailed info.

best teacher in the world. such a good summary . thank you

This pro. is so good at lecturing, the course succinct and simplified. Love from Cambodia.

I loved it good explanation . will think of definetly subscribiing . straight to the point

Georgia Cornwall has done a conscientious job at teaching molecular and cellular biology -- and I enjoy it daily! :)

Awesome lectures by Sir. he explain every step and every single reaction with detail thank u.

It was informative in a simple way and the question after make you make sure you got it

There are mistakes in the video and they make the material more confusing than it should be.

A very concise content with relevant short videos and quizzes. Great program

Coronavirus. Relevant topic. Could not have been made available at a better time. Very good job 5 stars. I encourage everyone to listen to all the lectures in this track. Although, more and newer information is made available everyday, this course makes a great foundation for solid knowledge based. I like it very much. 5 Stars.

Aging. I like this topic because I also work with the aging population; so it solidifies and reinforces my knowledge on this subject. Now I can confidently deal with and answer in depth many of the questions that often seem obscure in the past. Great course. Excellent job Prof. Georgina Cornwall, PhD

I dont understand the neg review. This is such a good lecture covering the key points. I found it very helpful

I can easily follow the sequence of information. The important details are also emphasized, making it easier for recall.

Nice delivery but as much as Dr tries to break it down,it looks a bit abstract. Perhaps some mneumonic would help

I really like the explanations and detailed structures used. The structures make it easier to understand.

Ver clear good graphics explained simply good questions best lectures

I love it that I get a clearer view of the topic. The lecture is straightforward. Yes, I would recommend to others

The lecture is organized and precise. I would recommend it others. Moreover, it's less time consuming and as I said highlights what material is needed.

Very clear and easy to understand. I enjoyed the visuals.

great lecture, i have been a doctor for a decade but nice to review this topic with such a brilliant lecuture. Thank you so much for your help.

I find the information useful and presented in a simple manner. The professor is kind and provides the students with logical explanations and tips on how to memorize things.

much wanted detail. thank you so much, perfect and informative.

The explanation are cleared. However, they are not included many scientific terms and scientific details that necessary to well understand the content and to do well in the MCAT exam. In other words the content of that lecture are too simple for MCAT students.

I understood very well the topics. I learned things I didn't before in school

very precise, for a person with basic knowledge it is very helpful although I think it could be a bit difficult to understand for someone who does not know anything about these issues.

Professor Kevin make it enjoyable course; It helped not only in remembering many info that I forgot in the class, but also I did learn many new valuable information. The fact that the explanation provided by Dr. Kevin is so easy to understand and memorize, make this course very interesting.

The explanation about the carbs are very clear and detail. Which make easier for any student and professor to better understand the carbs, their pathway, and the enzymes that work in those pathways.

I am a biochemistry student, the videos on lecturio have been so amazing. The lectures are superb. The language is easily understood and in a very friendly way. The concepts are been discussed fully and appropriately. It has made me to understand biochemistry more.

the material had been given clear easy to understand .Helpful in clinical practice and updated ,which is super impoertant

I love cell biology and this classes are amazing. Thank you

sorry, my english is not so well, but it is very well here

ok ok ok ok ok ok ok ok ok ok ok ok

Super simple and short! Great introduction to bacteriology and covers the major points.

I am updating my knowledge base in microbiology as I dive into teaching the course on a more regular basis than before. The information presented in these videos is concise, delivered well by Dr. Racaniello, and given in small chunks that make it easy to stop and come back at a later time.

The most fun I had learning about bacteria. That Italian New Yorker accent is everything! His E. coli lectures are the reason I passed my midterm and can totally discuss anything E. coli like a pro. So happy I discovered him and will definitely come back for more.

Thank you so much It was great I enjoyed watching these videos

just got the structure formation of a f actin support epithelial

How can the process of charging of tRNA be explained if the concept of tRNA has not been presented? What tRNA does and then how it's charged. I am loosing too much time googling stuff. Maybe it has been presented, but it's not part of this playlist, which should be complete.

Simple. Precise. Very good. Don t waist any time. This topic is very high yield for any medical test.

This course is easy to understand and memorize. I am 100% recommending this course to anyone in need of learning sciences.

Very good teaching. Very good images and very good explanation.

This is a very clarifying lecture on Listeria, taught by a professor with very good teaching skills. And kinda funny.

This explanation was not clear at all. I had to research a lot of information elsewhere to understand the concepts presented. This is the exact opposite of what is to be expected of something that should make students life easier.

I like how Dr. Kevin discussed all the topics, simple and easy to understand.

ten words ten words ten words ten words ten words ten words ten words ten words ten words

Why does it require ten words and stuff, can't I just rate the lecture and get over with it?

Course is not only informative, but very enjoyable to listen. Also, I love your dressing style.

What I love the most about this course is its Easy to follow & efficient delivery

very clear and detailed explanations,basics and detailed information is well explained.

Very concise and simple explanations. He made it easy to understand.

Makes the tough subject easier to understand . This app has shown very beneficial. I think I will buy the year subscription after my 3 months are up

yummye yummy yumme yom? yommer yom yom yom; yom yom yom.

Simplified and we'll explained. The teacher knows her topics well and explains in a simple way for all to understand.

Clearly explained, using correct words and always summarizing the whole subject

The lecture breaks it down so simple that it’s easier to understand. There’s still more factors that I’m sure they’ll be discussed in other lectures but it’s perfect to help to create a strong foundation in your knowledge

Nice and comprehensive overview! Easy to understand/listen! Bacteria made easy.

He speaks very well. Concepts delivered very well. I could understand most of his theory

Concepts are very good and explanation is amazing. I'm in love with it

Excellent content, well delivered. Great review for me since it has been over a year since I took microbiology.

Great Visualization and the elaborative method of teaching is right according to my mind.

Perfect... I undarstant many things here... Nice explanation Wish best for you

Amino acid MetabolismThe lectures are very thorough and give good details about what is high yield.

Best videos for usmle preparation Everyone joined this Most intelligent teachers

Microbiology is a founding block of all things medical. Professor Racaniello made not so easily pronounceable words sound so easy. His pace and style being so pleasant, he made it attractive for me to sit and focus start to end. I look forward to more of his lectures.

They are chunked in small amounts and presented very clearly. The visuals are excellent and the professor’s pace is terrific.

Brilliant course. It has a great differential diagnostics and an overall content is really good.

It's amazing how easy to understand this hard concepts can be with the help of Dr. Wilson

Dr. Ahem explained a complex concept in a very interesting and simple way. Straight to the point and informative. Thank you

Great to be with you on this platform as student studying medicine hopefully need to be lovely doctor

very good knowledge gained. Learnt a lot about RNA and DNA and messenger RNA

very clear , and natural. High yield, very in depth. Great knowledge gained

brief , clear, high yield, relaxed, in depth lectures. With a question and answer section at the end of every lecture. I'm loving it

One of the best teachers in Lecturio my personal favourite class

FINALLY! I get replicated homologous chromosomes! Professor Cornwall cleared up a haze I had about this point for years in 3 seconds. I don't understand why there are not more people who emphasis the difference between homologous and replicated homologous chromosomes. Thank you Professor Cornwall.

I haven’t seen such an amazing teacher in my life My most favourite teacher

The concepts mentioned in this lecture are very confusing and poorly explained. She made no effort to clarify the meaning of homeodomain, homeoprotein, and other such concepts. Also, she seems very unsure of what she is teaching and the speed is too fast to properly retain the information.

Rather than giving us mnemonic, I'd rather had him explained. I had to go to Youtube to find out what this means and it took me a lot of time.

very bad organization of the material vitamin d , then calcium, then vitamin d, then calcium. and there are lots of overlap between classes

Dr Kevin explains the concepts slowly and with emphasis. He also includes the physiological aspects, making biochemistry sound more biological rather than chemical

I loved this lecture ´cause dr ahern was so clear and it really helped me understand this topic.

I love the way the professor teach and the PPT are well planed

Awesome review , covering all the important concepts with clear explanation

The professor teaches very well, and difficult concepts are taught in a clear, concise manner.

Basics of this course can be explained in a very detailed manner

not enough details, like the fast staph. is Catalase-positive and non motile . more details needed.

It was very comprehensive and I loved how easy it was to understand

I liked the course ,but a little more explination is needed in each of the clases

All of the videos on this topic are very good, thank you!! It made me finally understand it. I wish we would have more details on the pathologies related to the Purine and Pyrimidine pathways.

It was awesome factual and easy to understand.Amoino acid Metabolism clear relationship to general human Anatomy.

I LOVE THIS DOCTOR , he make the lecture more absorbable

I really appreciate because it helped me a lot to grab such a complicated topic in a simple or decent way.i can't explain.eventually I loved to learn subjects in this manner

The lecture was simple understandable and Clear , it gives a broad explanation about the fundamentals of biochemistry

Amazing Dr. Kevin! Thank you very much for this course!

It is comprehensive pike of knowledge.in short I appreciate the effort of whole Lecturio team to cover difficult topics in such a easy way..I can’t explain.I loved it

Excellent lecturer. Manages to efficiently explain concepts in a very concise and informative way leaving very little room for confusion. He's obvioulsy a master in this field and I'd definitely recommend his lectures to anyone.

Short and simple. Right through to the significant things. Thanks to the professor.

I appreciate these refresher and very well-explained building lectures.

He was very wholesome,calm,clear composed and his use of references to his experience were wonderful.

The lectures are well explained and he made it easy for understanding the microbiology concept

Made something so complex easy. I've always had trouble here.

cannot understand a word. info given are too summary and unconnected

The content of the lecture/presentation is excellent. Has somebody else prepared the material?

Yes, hormones and their transduction signals are important like a cardiac conduction system starting form the Sino-atrial node (SA) finishing in the Purkinjie fibres . I mean Hormones and signal transduction are really well explained by a doctor doctor Kevin Ahern . He has been presenting the most complicated part of the medicine course so well. In terms of pregnant patient for example who does need an extra attention and management as they go though various hormonal changes while caring out pregnancy and delivery tasks. I cant thank enough for his contribution . I much appreciated.

Only wish the section would have also included videos or as link to videos posted elsewhere to Vitamin C, B1,B2,B6 and the rest of the water soluble Vittamins.

I choose this rate because Dr Vincent deserve it. I really really like it. Definitely I will recommend to other students.

I like it very much because it explains in detail . I will recommend it to my fellow medical friends . Thank you Lecturio

The lecture were so concise and upto the point. The questions following each video were very helpful in remembering the key facts.

no sound on the video. no sound on the video.

It is Clearly clearly Clearly clearly Clearly clearly Clearly clearly

I loved this lecture! Everything was so well explained: simple, straightforward, and I especially love few external tidbits thrown in such as the meteorite portion. It helps to remember these facts. Thank you!

This lecture was one of my favorites as it made something so confusing perfectly digestible.

Dr. Ahern is a very good lecturer. He explains concepts very clearly.

This lecture provided me with so much clarity. Thank you

aa a aa aa aaava aaav aaa aaa a s s s

Excellent resource. Thank you. I also enjoy the quizzes and practice medical scenarios.

simplest and clear and touch the point figure help in understand

in depth knowledge on DNA splicing, ecor 1 and so the base pairs want to stick together and then ligase comes along to stick together the backbones, the phosphate-sugar backbones. Here you can see how the two pieces come together and now we have a recombinant DNA molecule. Again, we are generally looking at a circular chromosome and a foreign piece of DNA being inserted into that circular chromosome and so we'll see two ends of sticky ends and insertion of that sequence.

This lecture gave me a brief knowledge on how rDNA is made.

Easy to understand I like that subject Clear explanations relevant for my dream job

Hello Dr Elliott, Yes this course is very complex and very interesting !!!! Especially pathogenesis part I think very important!!! As all treatment depends on it! Yes ,I do like this COVID 19 course ! I have taken so long to read those sessions as trying to compare from other sources if it had differences. That why is more interesting to study and memorable! I always love to study with differentials! Sorry about that that. As it is a new virus + with various subtypes , I am taking my time to study rather just reading ! I study to gain knowledge and skills not for a certificate Therefore I may take longer time And study all the details . This course is amazing I still think COVID-19 needs to be studied a very profoundly in order to have more effective and efficient treatment for the patients who experience this dangerous COVID-19 disease Especially I think post- COVID recovery’s very important as well. Many thanks for your great talk . Excellent explanation , and content is very informative . Dr .Gulbanu Akimgalievna

He explains on a perfect and short way making it easier to understand

It is fine, like it very much. Very informative and useful

Wonderful, simple and easy-to-understand video. Finally got it

This video has several problems. It does not seem to be a continuation of the previous ones, it has unclear information, the reparation itself is not explained, and the name dropping doesn't help either.

a good update for a recent pandemic that has negatively affected so many communities

Definitely recommend to everyone, informative and concise, looking forward to more lectures by Dr Sean

I liked the lecture. It was clear and concise. I liked it better if the lecturer used more visuals of techniques.

Very informative and detailed. It allows you to understand the concepts on a fundamental level.

The information was specific and to the point. The power point went with the information presented. It was easy to follow and understand.

The best explanation, Concise and to the point. Thank you so much.

Nice summary comparing and contrasting other differential diagnoses and walk-through of a typical case of COVID.

waste of time for usmle prep highly dont recommend. thats it

It is helpful and updated And with presences of quiz it condence information.

Excellent review of the basics; been a practicing Doctor of Chiropractic for 27 years and your videos are bringing it all back again! On the way to taking the MCAT to get my medical doctorate in Pediatric Neurology specializing in neurosurgery. Planning on beginning practice when I am around 68/69...my second career. Thank you for helping me do this great endeavor!!

Very clear and helpful to understand the physio. Dr. Raj's lecture also was great because he went step by step and explained the stages more like a story which makes it easier to remember.

Clear, structured information. Up to date and well done! I would recommend this lecture.

This review, expose the useful tools Anion GAP and Osmolar GAP, it is easy and complete.

Love this lecture. Dr. Ahern explains much better than my professor.

I FULLY recommend!! Definitely has help out in my courses.

I liked this lecture and I also like this teacher. I just sometimes find the explanations a little be confusing.

A student could do this lecture and it would be easier to understand. we expect better lectures from professors.

Coming from someone that has never taken microbiology before, I feel as if it's explained simply without All the fluff, especially for a “Ph.D.,” which, from my experience, makes things more complicated than they need to be when giving lectures and quizzes. Ex. When I take the quiz at the end of each lecture I understand what the question is asking, and I'm able to respond Accordingly. This is what's missing in the science classes that I taken at the Schools I've attended.

This course are good and helpful every medical student .if anyone are complete nutrition course I think she / he achieved lots of skill about nutrition.

Five-star score not only for the high-yield information but also for the excellent teachers, spaced repetition tests and articles. Thank you all for bringing this amazing learning format!!

Great explanation, It's great how the lecturer takes the time to guide our mental process. He´s so far my favorite lecturer.

best explanation of the iron transport on the web that I have come across. Good clear diagrams.

It reminded me of most important concepts of the microbiology.

They give clear explanations on all topics in such a way that it is easier to grasp. I personally enjoy learning more about a particular topic and Lecturio is the perfect platform to do that as well. I highly recommend Lecturio to all students for better understanding of relevant topics.

Really good explanation. And I like the professor. I understood

I believe this course is an excellent review of genetic basics, techniques and clinical correlates

Thank you so much This video helped me so much en my sesions of study

I loved how thoroughly the pathogenicity of each microorganism was covered. It was also great that the Professors explained, in detail, exactly how the microorganisms infected their target cells.

Very good lecture! Interesting clinical correlation (celiac disease). Thank you!

I think I choose this because is very understanding the classes and the Dr is very practical

I'm really enjoying Dr. Cornwall lectures, I love the way she explains things!

I like how the explanation goes, including the updates. Maybe if there is time, the staff can insert the updates in the lecture material. Lecturio is awesome. The repetition in the quiz is good for recall. My laziness to keep redoing the questions is being challenged and I have to do it because it is for my own good.

Clearly presented talks and material. Very useful for undergraduate students.

Please is important to add more clinical correlation, clinical cases and bridge to other areas: pharmacology, microbiology, etc. Usmle test the integration of knowledge.

Comprehensive, latest information presented in an easy to understand formats. Thanks!

Interesting. I have tries to learn this about 2-3 times but never quiet stuck in my mind. Too easy to forget why an enzyme does this or that, however Dr.Kevins way of sharing the WHY this is significant really helped conndct the dots.

The way he explains was easily to understand and memorize. Thank you..

Great lecture, easy to follow and understand! I cannot rate every video as rating is complicated, but I really like his way of teaching

Interesting. Mental thirst quenchinly good. Interconnected. Just enough info. Dr.kevin fun lectures.

I really appreciate how Professor Ahern broke down this topic (no pun intended). He does a really good job at tying things from other lectures together really bringing these pathways together while also trying to enrich our understanding of the context behind em. Thank you for your hard work!

I honestly had a lot of fun listening to Professor Ahern. You can tell he is really passionate about Biochem. I learned a lot. Great course if you're interested in understanding aspects of the metabolic pathways conceptually while appreciating the details/context that enrich your understanding of them and how they are interrelated.

Nice review, but I would expect at least 2 things: 1) Recommended daily amounts 2) Information of absorption 3) Information on minerals 4) Information on macronutrient intake

Beautifully described. Clear and concise presentation. Your all lectures are brilliant

ok. could use improvement please include that Kinesin and Dynein are ATPases that use energy. also that only Kinesin is displayed here. I was so busy looking for Dynein information, that Kinesin info went out the other ear. This could be better by improving the diagram.

I liked the way the R and T states where explained. It all became very clear

I thought the introductory lectures were to indroductory and to much of a waste of time. I felt they introductory lecture were a insult to a medical students education level. I almost turned them off and went on to another section but, much later the same professor started to increase the level of knowledge in each video. This is the reason I am giving four stars. Please revise the introductory lectures in microbiology. A USMLE student does not have time to waste. I'm not done with the lectures on microbiology so I'd also like to comment later and here I feel I have been very generous with my review.

This course is an excellent presentation of biochemistry. Professor Ahern presents the material in a clear, concise, easy to understand format that is easy to follow. I really like that I can pick and choose the lectures I need to watch, particularly those that I need to prepare for my upcoming exam. I find the review questions very helpful. Overall, I am finding the course very helpful and I am looking forward to completing more of it.

I like that Dr. Ahern's way of presenting the topics is informative and does not make me sleep. Usually, our classes make us feel drowsy because of too much information. It helped me understand the concepts more and I was less distracted.

It was easy to understand, and some details, which i think was enough! not too much information, but enough

Thank you Dr. Ahern for this very comprehensive lecture. Going through the biochem book makes this topic very complicated. It is amazing how you can simplify this topic to get to the point and what we actually need to understand.

Difficult to memorize all pathways I think it could be more interesting

Like the step-by-step discussion. Make it easier for me.

Covered a vast portion of the basics that are the most important part of the foundation. The structure of the course is phenomenal and the way it is carried out is engaging and made extremely interesting. Concepts are crystal clear after going through the whole course. Thank you so much, psyched to have found this! I only wish this material was downloadable for future reference. Hoping it could be. Thanks again! This has cleared the slightest doubts Ive ever had, hoping to have many more courses conducted by Georgina Cornwall.

not very engaging with the viewer, and it could be even more dynamic

I love it! It's clear and concise! Dr.Ahern is a gem to learn from. He breaks it down to where I can understand.

Nice speaker and illustrations. The lectures were engaging. Thank you!

This topic is OVERLY simplified. It needs more in-depth explaination, which she claimed to offer later. But this brief section creates even more confusion... Maybe it is better to do a PROPER introduction, or just cut this one out... Also, she herself seems to be unsure and confused. I am not sure what her profession is, but DNA doesn't seem to be a topic, which she should lecture on... In the middle of the video she just blanked, and kind of skipped on some points... (That's not the first time or first lecture that she does that...) P.S. The powerpoint is also not accurate... The coding strand around 0:52 is indicated as template strand... This lecture is quite disappointing, and frankly, a very low quality compare to other Lecturio's lectures.

Really good divided and explanation, with good examples and great review questions

Comprehensive course with exemplary format & teaching style to explain core concepts.

Aminoacid metabolism Is not easy to understand but still good !!

fast confusing order of explaining Its not like it simlifies anything the way its explained is quite fast and confusing very mono tone

Muy bien explicado y presentado por la presentadora, además de diapositivas muy explicitas.

Kevin Ahern is a really good teacher, I really enjoy his lectures, but sometimes it's hard to follow the lecture due to the presentation picturing one thing and him talking about something else. And also when he's talking about about the presentation I wished he had some sort of pointer so I would be easier to know what structure he's talking about????????

More organization is needed to explain this lecture because is an important part of the DNA synthesis.

It's well presented and relatively easy to understand. It has helped me understand various concepts

With this topic is easy to get lost ini all the details and I think he made a good overview to not forget de bi image when we get in the details

I love her course. She explains in a very understandable way.

Professor gives a very clear explanation, easily understand. Thank you.

Beautiful and very good explanation . easy slides. thankyou. study matter also provided

More emphasis on how the usmle style questioning will be asked

The narration is a bit fast animation and concept understanding is nice

Content is spot on. And quizzes at the end of each videos are very helpful. Hope Georgina used a cursor or infra red light to point exactly what she was talking similar to other lecturers from other videos. An animated video clip of how each or some of the topics would be very useful.

Hello, I love supporting women in science and education, etc. I also will share my honest opinion to improve the educational site. This lecturer, while alright, is not the best you could get for Lecturio students. Her constant glancing over her notes is distracting and she is not very well articulated. Even though she is Ph.D., she has not digested her lecturing materials to the master's level. It is very unfortunate that she lectures on one of the most important subjects within your platform. Why you chose her? For the sake of diversity and involvement? I am sure there are much better and knowledgeable lady lecturers. Did not you see the disengagement and flaw after a couple of her lectures? Was she so cheap?

The presentation is very nice and helpfuly The organization of topics was very good

I like it very much but the only issue is that the lectures are not complete about all the bacterial species of myobacteria for example, and I'd love to study all of them with lecturio cause it's simple and easy to understand so that I don't have to study the unavailable topics on other websites

Very well explained and fascinating lecture! Thank you very much!

Concept clearly explained. The professor is very thorough in the description of acid base balance.

I am no longer scared of metabolic pathways. thank you so much.

I'm impressed with how high yield the information is. The professor touches very important aspects in just the shortest time that one video has, and that is really impressive. I do have a degree in Biochemistry and molecular biology and so this is really making me master the course gradually. For sure I'm recommending this course to my friends from same college already who aspire studying medicine like me.

I liked to much because maintain the point of what are she explaining the theme with clarity and didactic form about the macromolecules of life the first principle to begin the content of the nature of the Body , systems organs ,tissues and cells.

Very interesting lectures. I really injoy the way you explain the topic. Thanks a lot!

I got to say, i love Racaniello's videos on microbiology so far. But this series of the enteric bacteria is confusing and disorganised. Some of the slides provided are different from the ones used by him. Sometimes the script adds some erroneous information, making the already confusing explanation even worse.

I like all your lectures, you give a great explanation of the material, thank you, Professor!

Thank you!!! All your lectures are very interesting and with nice explanations!

Incredible Easy to follow the class The professor had my attention all the class

It was hard to understand It could be better another way to explain the topic

Biochemistry by Georgina Cornwall is not good at all, she reads all the time and she doesn't even know what to talk about.

She didn't talk about the template strand. the prof fumbled with the coding strand and im actually confused if the coding strand, or the tremplate strand matches the sequence of the mRNA. She definitely seems disorganized. It didn't flow at all.

The videos are shorts and specific an also great explanations

I liked these explanations, but if you are a college student this may not be for you

Really course is wonderful, and very useful and Professor has easy and simplified explanation of most of the complex topics in biochemistry.

The concepts are very clear and have been presented in a simplified and comprehensible manner.

Great explanation with great examples . Knowledgeable in subject matter , content up to date

THE TRANSLATION IS NOT CORRECT, THERE IS NO CONSISTENCY IN THE SENTENCES

Very condensed, but a well-taught lecture. I love the teacher´s style.

Thankyou so much for the opportunity to relearn most of the important and key concepts related to this cornerstone foundation to Medicine & Life Sciences! Wish I had this tool in my undergrad days!!

Dr Raj is so good at reminding associated pathologies!!! Perfect for an overview

Nice explanation, very useful, easy to follow. very useful reminder of basics.

SHE IS NOT CONFIDENT IN TEACHING AND RUINS THE MOOD OF LEARNING

It was a great lecture, I learn a lot. Thank you Prof. Ahern.

He is the best here , I swear Idk but I like him

Thank you for your interesting, useful and simple way do explain difficult things!

Thank you, dear professor for amazingly informative and interesting lectures

An excellent course. Simplified most important topics needed for exam.

Its excellent because there is more physical and clinical correlation and enzyme mechanism simplified

Great course for introductory level biochemistry. Prof. Kevin Ahen is a great teacher, knowing not only the topic but it's historical background...

I like the lecture because is easy to understand, the use of examples are really helpful.

I noticed that there weren't any lectures on mineral metabolism in the library. I think students would really appreciate it if you made a module on this topic as it has a lot of biomedical importance and some relevant diseases are associated with it.

He's a legend ooh I don't know what else should I say to complete 10 words

biochemistry was tough as I havent chemistry before. Had to keep reviewing, loved the tests and course presentation and so satisfying when i got the answers right. Great system for people like me . cant wait to do other subjects when i finish this one.

i like but the fomr like the professor express can distract a little

I like this cause of a simply explaining things, and I would like to recommend it for nurses and also doctors.

It was an effective method to aquire the knowledge required for that interesting topic; thanks so much indeed for such fascinating and entertaining lectures even though I wish you could increase the number of them as I really enjoyed every minute spent learning that session.

such a hard concept explained so easy and well. such an amazing work sir

This needs to be slowed down and more visual than it is.

La verdad es que es muy buen curso, el ponente explica demasiado bien y me gusto mucho qué hay actualizaciones

I loved this lecture! Now I truly understand the first two weeks of embryo development! Thanks Dr.Peter !

what an amazing lecture god bless u sir and i wish to meet u someday

Each and every concept is explained with each lecture it has helped me in getting to know things well rather than just learning.

I use Emery’s Elements of Medical Genetics 15th edition as primary study material, which i recommend for anyone to use. I decided to take this course as a supplement and ended up confused and annoyed. Simple learning objectives of this course lectures are harder to understand due to poor explanation and as far as i can tell the professor seems stressed, disoriented and confused herself. Lectures need a rework. Despite that, the articles are pretty good and helpful, PowerPoint slides are useful to an extend.

All lectures by Dr. Wilson are awesome. Explanations and pronunciation are perfect, especially to people like me that speak a diferent language. Every lecture is very easy to understand. I am very happy with Lecturio!! Thank you!!

Great teacher. Well explained. Learning outcomes well defined and all comprehended.

The introduction provided me with the basic concepts of genetics

Thank you so much; Nonetheless, i really need to let you know your vocabulary is above my reach

I could not understand it good at that in my university college friends

Great explanation about the Bohr effect, thank you very much doctor

I understand very well, thank you Professor Kevin, these help me a lot

Dr. Ahern pointed out very interesting aspects like heat generation/high energy of PEP and the 2,3-BPG production. Maybe I wasn't paying attention the first time I learned about glycolysis, but this extra integrative information it makes this step easier to remember. Actually, in generally, these human focused biochemistry lectures, are easier to digest, since when I learned it originally, it was mixed with plant and microbial biochem.

Enjoyed the format for this and other Lecturio classes. Graphics are concise. Instructor is very good at explaining concepts

one of the best teacher ..yo mam ............really enjoyed it

It was much needed review for me in general. Thank you.

Enjoyed these videos very much. They helped me understand concepts I was struggling with.

Great work here,,, I’m so happy for the clearly understandable English

The content but also the Professor Vincent Racaniello, he is convincing , spacing and detailing what is needed to be captured.

i liked the details and visualization. should have been there more mobility in the slides tho.

The lectures on Enzyme and Enzymes Kinetics were thorough. There were detailed information on some important concepts.

Really well explained. it was simple and concise but informative.

Very annoying style of presentation. I do Cancer research for a living in the USA and I found a lot of problems with this presentation.

Professor Racaniello masters the topic very well. He knows what he is talking about. I like his confidence. He is one of the most fluent professors I ever have

if i wanted monotoned reading i would have read textbooks instead of watching this video.

Need to explain better as it is very complicated and confuses us even more than we were before

Nice course very complete in every sense, I like it, keep like that.

Excellent professor. I think this lecture in particular (fungi) is quick and just the essential facts.

Love the lectures and reviews and quizzes and the fact that you can repeat for more clarification.

Amazing lecture! So easy to understand and so enjoyable to watch; congratulations!

Great information, concise, and understandable making it relatively easy to follow along. Thank you!

Awesome overview! Thank you! Particularly liked the gluten example. Also graphics were good - will stick in my brain longer.

Lesson was so fast and not understandable .Lecturer should have gone from easy points to harder points.She could not make it easier this topic for me .She did not use her hand at all during the lesson.This is so lazy way for giving a lesson and unproffesional.

The objective was to mention which diseases are AR and it was covered correctly

Poor presentation. It's just like he is reading out from study material. Lacks concepts.

I dont know if its the diagram or what the doctor is saying but i just cant understand the MAP kinase and the GEF and everything else afterwards

I just find the need for an extra time revising this, particularly offline. I always find my self making some notes unlike Anatomy!

better way of making it very interesting,short lectures. easily understable

Concepts are well explained .. I’ve learned more on lecturio than my class lectures

Prof Ahern explains very well & makes the key steps/enzymes memorable (eg PEP is full of pep!)

So good explications with a nice and simple way . I really appreciate your effort .

Good explaination, Love it! Easy to Understand, Keep it up!

Simple and easy going explaination! easy for me to understand. Keep it Up!

Explica las cosas super simples y puntuales, se memoriza rapido de esa manera

she reads from her notes too much, strikes me as someone who does not have a firm grasp on what she is teaching.

I think it’s too fast, and not with details so please correct these problems

Magnificent lecture about polysaccharides and their functions for storage and release

Very clear and succinct. May have gone a bit too fast, but that's always manageable

The video highlights the important concepts about the hydrophobic amino acids group

This lecture was great! I could understand what the professor was explaining and I understood it pretty well.

I recommend include the cc out of slides screen, the letters do not allow to watch the information

The lectures are very thorough and give good details about what is high yield.

I love the way he explained enzyme.... A brief and easy to understand lecture

Very interesting and engaging. The energy from Dr. Racaniello is absolutely contagious, thank you very much!

adioasd oiaj doias ds dioas jdoias jdoas djoi asdjoia sd o

Basic topics which i had difficulties in understanding has been well explained and now I have fixed the knowledge :) Suggestion: it's hard to cover the extremely fast growing biotechnology topic but I guess "omics" would be good to add

Thank you Dr. Kevin Ahern. You made me fall in love with biochemistry.

I haven't reviewed the lecture but personally from watching some of the previous vids I feel that doc Vincent is not giving a USMLE lecture. while what he does is very good, lecturio is very specific for USMLE, the lecturer has to hit the most high yield points in the most concise and easy to understand way. the benchmark would be Hassan sattar in pathoma, very on the point summarizing massive topics to a single slide.

Definitely enjoyed this lecture. Concepts were concise making it really easy to follow. I enjoyed actually practicing the case study questions as it tested my understanding of the topic

I really liked the explanation, finally after 2 years, I understand this!! Thanks :)

I like the way you explained how this signaling process work

It is really concise. He did a good job pointed out the importance of Aquaporin-2 in the body (specially in the kidney) and why we should care.

I always enjoyed Dr Ahern's handling of the Biochemistry subject, especially his eplanations

I really liked it and enjoyed Dr Cornwall'ss explanation. The only issue was that the video slowed at some point.

Despite the mishaps, I thought the information was understandable. Especially the ending when she connected Trp and Lac operons with repressible and inducible.

I like how much simple he makes the tough materials in pharmacology course

It's is just good that's why 4. I dislike that it's doesn't explain clinical too much

It's okay.... But somehow hard to comprehend. I will love if you can make the teaching much easier to grasp.

Most of it was good and understandable but towards the end, it became quite confusing to follow along.

Every slide has been clearly explained in detailed form. Thanks sir.

It's unfathomable how much this lecture has saved my time. Though I would appreciate a quick-summary of the products turning into intermediates for other cycles. Like with how g-1-p turns into g-6-p

I saw many times the video, take notes but I don't understand at all this video; think is some confusing :(

The lecture simplified glycogenesis to extreme simplicity. It truly helped save around 30 minutes from my lecture, by providing adequate information

Hi I appretiate her lectures about biochemistry, l hope the following lectures would offer me more interesting information.

Too fast and sometimes lacking pretty basic, though essential details about the whole process.

This lecture is very informative yet concise. Everything that you need to know is here. Thank you

Excellent, clear, interesting and informative presentation which facilitates comprehension and memory of essential material.

lecturer is breathing heavily that is kind of distracting. I don't know if it is because she is wearing the mic very close. lessons were nice tho.

this is amazing thank you , i gained a lot of info about viruses that i have not know before
