Reports have surfaced of individuals being re-infected with Covid-19, raising questions about immunity via natural infection as well as questions about the utility of vaccines. Here we take a look at the data to see how common...

Blood plasma from recovered patients may help treat other COVID-19 patients. <br/>

In this video, we discuss the physiological and biochemical differences between celiac disease and gluten sensitivity, both of which actually do exist, but are diametrically different in mechanism.

This video discusses the uses of monoclonal antibodies, which are all produced from a single clone of cells and are specific to one binding site on one protein antigen. The video explains how monoclonal antibodies can be used in...

As COVID continues to spread around the world worrying variants are beginning to emerge. These primary variants of concern have emerged from Britain, South Africa & Brazil but now they can be found in an estimated 100 countries. So in...

The trigger for rare blood clots occurring in patients who receive the Oxford-AstraZeneca COVID-19 vaccine may be a type of protein in the blood that is attracted to one element of the vaccine.

Vaccines contain weakened or inactive copies of diseases. When injected, they stimulate the immune system to develop immunity against those diseases, protecting individuals from future infections. Vaccines have greatly reduced the...

As always, the steps of an SDS-PAGE will depend on your specific lab and protocol. In this video, we will explore the general theory of separating and visualizing protein by SDS-PAGE, a technique very similar to DNA agarose gel...

With some basics out of the way, we are ready to get a sense of the overall structure of the immune system. That will mean looking at the lymphatic system. We already looked at this system in the context of its involvement in the...

Potential vaccines for the coronavirus are all over the news right now, and we all hope that a safe an effective vaccine is developed soon. But vaccines aren't the only tool in the pipeline. Right now there's a lot of research happening...

The video is about the components of blood and their functions. It starts by introducing blood as a fluid that transports substances to and from body cells. The video then describes the different components of blood, including plasma,...

The video discusses the process of immunization and how it works in the human body. It explains the role of the specific immune system, lymphocytes, and antibodies in destroying pathogens that cause diseases. The video also highlights...

Myasthenia Gravis | Pathophysiology, Signs & Symptoms, Diagnosis, Treatment



Myasthenia Gravis is an autoimmune condition involving the production of autoantibodies against particular parts of the muscle and neuromuscular...

This animation is about a Real Leptospirosis case I encountered during my training at Medical ICU. I talk about Microbiology, The initial symptoms, Complications & treatments for the disease. The causative bacteria are Leptospira, a...

It describes various means by which an individual acquires active and passive immunity.

In this video, we discuss how blood cells are made - everything from red blood cells to white blood cells and platelets.

White blood cells, a.k.a. Leukocytes. These are the second most common cell type in the blood. But what do we know about their structure and what exactly do they do? Well, that’s what we cover in this video.

Do you know your blood type? Even more - do you know what it means? By the end of this video, you'll understand the physiology behind blood types. You'll also understand the significance of the ABO and Rh Blood Grouping Systems.

What blood type do you have? Is it A, B, AB, or O. And are you RhD positive or negative. In this video, you will learn how to use the Eldon Blood Typing Kit to determine your blood type at home.

You’re infected. Something harmful is in your body and you gotta get rid of it. In this video, I’m gonna talk about four ways your immune system attacks everything.

This video provides an overview of how monoclonal antibodies are produced. It starts by explaining the role of lymphocytes and antibodies in the immune system, and how these antibodies bind to specific antigens on pathogens. It then...

Physiology of Basophils, Mast Cells, & Eosinophils

Get Rid of Your Acne: The Real Cause

Inventors are using small-scale biology and engineering to find ways to use the body's natural defenses to effectively treat cancer. National Science Foundation-funded small business GigaGen uses microfluidics, bioinformatics and genome...
