Amyloid plaques are aggregates of misfolded proteins that form in the spaces between nerve cells. These abnormally configured proteins are thought to play a central role in Alzheimer's disease. The amyloid plaques first develop in the areas of the brain concerned with memory and other cognitive functions. The amyloid hypothesis Amyloid plaques form when pieces

Testosterone is the principle sex hormone responsible for the development of reproductive function in male vertebrates. Testosterone is one of the hormones referred to as androgens, which are also known of as anabolic steroids. As a steroid hormone, testosterone is derived from cholesterol and the structure of this hormone is similar across all mammals, reptiles,

Today it is also used as limit test for particulate matter in parenteral solutions of large volumes. Since Coulter patented a method to

A voiding cystourethrogram (VCUG) is a fluoroscopic examination of the bladder and urethra while the patient is micturating.
