Endometrial Polyp
Endometrial Polyp samer kareem 20,641 Views • 2 years ago

Uterine polyps are growths attached to the inner wall of the uterus that extend into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps, also known as endometrial polyps. These polyps are usually noncancerous (benign), although some can be cancerous or can eventually turn into cancer (precancerous polyps). Uterine polyps range in size from a few millimeters — no larger than a sesame seed — to several centimeters — golf-ball-size or larger. They attach to the uterine wall by a large base or a thin stalk.

Obesity
Obesity samer kareem 5,815 Views • 2 years ago

Obesity is one of the most pervasive, chronic diseases in need of new strategies for medical treatment and prevention. As a leading cause of United States mortality, morbidity, disability, healthcare utilization and healthcare costs, the high prevalence of obesity continues to strain the United States healthcare system. Obesity is defined as excess adipose tissue. There are several different methods for determining excess adipose (fat) tissue; the most common being the Body Mass Index (BMI) (see below). A fat cell is an endocrine cell and adipose tissue is an endocrine organ. As such, adipose tissue secretes a number of products, including metabolites, cytokines, lipids, and coagulation factors among others. Significantly, excess adiposity or obesity causes increased levels of circulating fatty acids and inflammation. This can lead to insulin resistance, which in turn can lead to type 2 diabetes.

PCP (Phencyclidine) samer kareem 3,555 Views • 2 years ago

Phencyclidine (PCP) was developed in the 1950s as an intravenous anesthetic but, due to the side effects of confusion and delirium, its development for human medical use was discontinued. In its pure form, it is a white crystalline powder that readily dissolves in water or alcohol and has a distinctive bitter chemical taste. On the illicit drug market, Phencyclidine contains a number of contaminants as a result of makeshift manufacturing, causing the color to range from tan to brown, and the consistency to range from powder to a gummy mass. It is available in a variety of tablets, capsules, and colored powders, which are either taken orally or snorted. The liquid form of phencyclidine is actually phencyclidine base dissolved most often in ether, a highly flammable solvent. For smoking, phencyclidine is typically sprayed onto leafy material such as mint, parsley, oregano, or marijuana.
