    Glomus tumor. These are rare, slow-growing, abundantly vascularized tumors localized in the temporal region. Deafness or throbbing tinnitus is often an early symptom. On a CT scan, they often appear cellular 'moth-eaten' - you can see right at the edge.

    What do you think is the most common disease in the world? The answer is fairly predictable. Colds🙌🏻 Specifically, we're talking about rhinitis (runny nose) - since there are so many forms of respiratory disease, this is an important clarification. And rhinitis itself is extremely diverse. Infectious and noninfectious nature, acute and chronic, primary and secondary, hypertrophic and atrophic ... Perhaps we won't name the whole list😁

    Our DNA carries viruses in its composition! A rather uncommon alliance, initiated not by our organism. The fact is that viruses use our DNA to reproduce - it helps them to copy (as DNA does). And in the case of a virus inserting its DNA into a reproductive cell - the child can get that DNA with the virus. And this process has been going on for far more than the first generation. This is what has led to the fact that now at least 9% of our genome are viral genes.

    Cold and freezing food So, can the latter exacerbate the course of the former? We are told about this pattern since childhood, but is it so true🤔 Have we ever been told about the correlation - how exactly does it affect the pathological process in the throat? Certainly not. Only some could make the argument that the cold stimulates the secretion of mucus than worsens the course of the disease. But that's not how it works. Ice cream and any other cold foods do not provoke excessive mucus secretion. On the contrary, they can soothe an irritated throat: a cold dessert will act as a mild anesthetic. However, you can consume such products only in small quantities. If you cool the throat for a long time - it will reduce the activity of the local immune response.

    Liver transplant surgery Demi Leigh-Brennan is a true miracle, because she is believed to be the first person in the world to have had her blood type switched after a liver transplant. A virus had completely destroyed her liver, so doctors transplanted a donor one. It wasn't the first surgery the doctors had done, so there wasn't much of note here, but the result was staggering for everyone. Demi was Rh-negative from birth, and after the surgery, she was Rh-negative, just like the liver donor.

    Enzymes are some of the vital "cogs" of our body. They are macromolecular biological catalysts that accelerate chemical reactions. The molecules affecting enzymes directly are called substrates, and then the enzyme transforms the substrates into various molecules known as products. Coenzymes are small organic molecules that bind tightly or loosely to the enzyme. By binding to the enzyme's active "site," it helps the enzyme do the job of making or breaking down substrates into products.

    The process of phagocytosis has been fully explored thanks to the sacrifices of sea stars and daphnia At the final stage of research in this field, these very creatures were used. Various foreign organisms were injected into the bodies of daphnia and sea stars. Those daphnia and starfish in which too many foreign organisms were introduced died. Their mobile special cells (that's what scientists called phagocytes at the time) simply did not have time to digest everything👐🏻

    How Typhus was defeated. The disease was carried by lice, from which there was no escape until the 1920s, when Professor Rudolf Weigl invented a method of obtaining an effective vaccine. The lice were deliberately cultured by feeding on the blood of what they called "feeders" by attaching the cells with the parasite to their legs or thighs. Adult lice were infected, then cut open and created a vaccine.
