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.

Hemodialysis Procedure #shorts #dialysis
Hemodialysis Procedure #shorts #dialysis Scott 47 Views • 2 years ago

The objectives of hemodialysis are to extract toxic nitrogenous substances from the blood and to remove excess water. In hemodialysis, the blood, laden with toxins and nitrogenous wastes, is diverted from the patient to a machine, a dialyzer, in which the blood is cleansed and then returned to the patient. Diffusion, osmosis, and ultrafiltration are the principles on which hemodialysis is based.

The toxins and wastes in the blood are removed by diffusion—that is, they move from an area of higher concentration in the blood to an area of lower concentration in the dialysate. The dialysate is a solution made up of all the important electrolytes in their ideal extracellular concentrations.

The electrolyte level in the patient’s blood can be brought
under control by properly adjusting the dialysate bath. The semipermeable membrane impedes the diffusion of large molecules,
such as red blood cells and proteins.

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

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:

Aspirin fights against cancer
Aspirin fights against cancer Doctor 7,345 Views • 2 years ago

A new well designed randomized study has suggested that long term baby aspirin usage may aid in fight against cancer. The suggested mechanism is that cancers induce inflammatory responses so the anti-inflammatory mechanism of prostaglandins inhibitors may cease the progress of many cancers. There are some concerns about the study because despite the well-designed randomized study; the study didn't include a satisfying number of female participants. The study was also conducted on esophageal, colorectal and lung cancers.
