A uterine contraction is a muscle contraction of the uterine smooth muscle.
The uterus frequently contracts throughout the entire menstrual cycle, and these contractions have been termed endometrial waves or contractile waves. These appear to involve only the sub-endometrial layer of the myometrium. In the early follicular phase, these contractions occur once or twice per minute and last 10–15 seconds with a low amplitude of usually 30 mmHg. The frequency increases to 3–4 per minute towards ovulation. During the luteal phase, the frequency and amplitude decrease, possibly to facilitate any implantation.
16 and Pregnant is an American reality television series that debuted June 11, 2009, on MTV. It follows the stories of pregnant teenage girls in high school dealing with the hardships of teenage pregnancy. Each episode features a different teenage girl, with the episode typically beginning when she is 4 1⁄2 – 8 months into her pregnancy. The episode typically ends when the baby is a few months old. The series is produced in a documentary format, with an animation on notebook paper showing highlights during each episode preceding the commercial breaks. 16 and Pregnant has spawned several spin-off series: Teen Mom, Teen Mom 2 and Teen Mom 3. Each series follows the lives of four girls from their respective season of 16 and Pregnant as they navigate their first years of motherhood.
As of July 2013, casting for the fifth season of the series is taking place.
Science of drugs including their origin, composition, pharmacokinetics,
pharmacodynamics, therapeutic use, and toxicology.
Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
