Genetic Disorders And Diseases
Genetic Disorders And Diseases samer kareem 4,445 Views • 2 years ago

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

The heart makers
The heart makers samer kareem 2,031 Views • 2 years ago

How do you make a working human heart? Scientists can turn stem cells into beating heart cells, but getting them to organize into a 3D heart requires a scaffold. At the Massachusetts General Hospital in Boston, Harald Ott and his team are reusing the scaffold that nature provides. They’re stripping away all the living cells from dead hearts, before filling in the leftover matrix with healthy new cells. In this video, Brendan Maher finds out how the technique could be used to develop parts of the heart, like the aortic root and valve, for transplant.

Why You Got Fat
Why You Got Fat samer kareem 26,580 Views • 2 years ago

The usual reason given for people getting fat is that they eat too much and/or exercise too little. That reflects one of the basic laws of thermodynamics—I forget which one. The amount of energy you put into a system minus the energy you take out has to be stored somewhere i.e. FAT! This formulation—true though it is—does not entirely explain obesity since some people seem to eat more than fat people and exercise no more than these same fat people, and yet they are not fat! Chalking this fact up to the general perversity of the universe is not sufficient explanation. Other factors must come into play. I mention below some of the ideas thoughtful people have proposed to explain why fat people become fat:

Vertigo Treatment
Vertigo Treatment samer kareem 2,754 Views • 2 years ago

Vertigo is a sensation of spinning. If you have these dizzy spells, you might feel like you are spinning or that the world around you is spinning. Causes of Vertigo Vertigo is often caused by an inner ear problem. Some of the most common causes include: BPPV. These initials stand for benign paroxysmal positional vertigo. BPPV occurs when tiny calcium particles (canaliths) clump up in canals of the inner ear. The inner ear sends signals to the brain about head and body movements relative to gravity. It helps you keep your balance. BPPV can occur for no known reason and may be associated with age. Meniere's disease. This is an inner ear disorder thought to be caused by a buildup of fluid and changing pressure in the ear. It can cause episodes of vertigo along with ringing in the ears (tinnitus) and hearing loss. Vestibular neuritis or labyrinthitis. This is an inner ear problem usually related to infection (usually viral). The infection causes inflammation in the inner ear around nerves that are important for helping the body sense balance

Cortisol and Glucocorticoids
Cortisol and Glucocorticoids samer kareem 3,629 Views • 2 years ago

The vast majority of glucocorticoid activity in most mammals is from cortisol, also known as hydrocortisone. Corticosterone, the major glucocorticoid in rodents, is another glucocorticoid. Cortisol binds to the glucocorticoid receptor in the cytoplasm and the hormone-receptor complex is then translocated into the nucleus, where it binds to its DNA response element and modulates transcription from a battery of genes, leading to changes in the cell's phenotype. Only about 10% of circulating cortisol is free. The remaining majority circulates bound to plasma proteins, particularly corticosteroid-binding globulin (transcortin). This protein binding likely decreases the metabolic clearance rate of glucocorticoids and, because the bound steroid is not biologically active, tends to act as a buffer and blunt wild fluctuations in cortisol concentration.
