A near-death experience (NDE) is the perception reported by a person who nearly died or who was clinically dead and revived. They are somewhat common, especially since the development of cardiac resuscitation techniques, and are reported in approximately one-fifth of persons who revive from clinical death. The experience often includes an out-of-body experience. The phenomenology of an NDE usually includes physiological, psychological and transcendental factors (Parnia, Waller, Yeates & Fenwick, 2001) such as subject ...

In biology, apoptosis (from the Greek words apo = from and ptosis = falling, commonly pronounced ap-a-tow'-sis[1]) is one of the main types of programmed cell death (PCD). As such, it is a process of deliberate life relinquishment by an unwanted cell in a multicellular organism. In contrast to necrosis, which is a form of cell death that results from acute cellular injury, apoptosis is carried out in an ordered process that generally confers advantages during an organism's life cycle. For ...

Coronary heart disease (CHD), also called coronary artery disease (CAD) and atherosclerotic heart disease, is the end result of the accumulation of atheromatous plaques within the walls of the arteries that supply the myocardium (the muscle of the heart).

Immortality (or eternal life) is the concept of existing for a potentially infinite, or indeterminate length, of time. Throughout history, humans have had the desire to live forever. What form an unending or indefinitely-long human life would take, or whether it is even possible, has been the subject of much speculation, fantasy, and debate.

Masturbation is the manual excitation of the sexual organs, most often to the point of orgasm. It can refer to excitation either by oneself or by another (see mutual masturbation), but commonly refers to such activities performed alone.

The September 11, 2001 attacks (also referred to as 9/11) were a series of coordinated suicide attacks upon the United States of America carried out on Tuesday, September 11, 2001, in which hijackers took control of four U.S. domestic commercial airliners. The hijackers crashed two planes into the World Trade Center in Manhattan, New York City — one into each of the two tallest towers, about 18 minutes apart. Within two hours, both towers had collapsed. The hijackers crashed the third aircraft into the U.S. Department of Defe ...

A timeline of apoptosis research can be found in Cell Death and Differentiation (2002) 9:349-54.[16] Apoptosis - Early research and the worm people at Cambridge. Sydney Brenner's studies on animal development began in the late-1950s in what was to become the Laboratory of Molecular Biology (LMB) in Cambridge, UK. It was at this lab that during the 1970s and 1980s, a team led by John Sulston succeeded in tracing the nematode C. elegan's entire embryonic cell lineage. In other words, Sulston and his team had traced where each and every cell in the roundw ...

Coronary heart disease is the most common form of heart disease in the Western world. Prevention centers on the modifiable risk factors, which include decreasing cholesterol levels, addressing obesity and hypertension, avoiding a sedentary lifestyle, making healthy dietary choices, and stopping smoking. There is some evidence that lowering uric acid and homocysteine levels may contribute. In diabetes mellitus, there is little evidence that blood sugar control actually improves cardiac risk. Some recomm ...

Apoptosis - Morphology. A cell undergoing apoptosis shows a characteristic morphology that can be seen under a microscope: The cell becomes round (circular). This occurs because the protein structures that conform the cytoskeleton are digested by specialized peptidases (called caspases) that have been activated inside the cell. Chromatin (DNA and its packaging proteins in the cell nucleus) undergoes initial degradation and condensation (see the article by Madeleine Kihlmark et al.< ...

Time Lords appear human, but differ from them in many respects. Racially, all the Time Lords in the television series so far have been portrayed by Caucasian actors, although a black Time Lord appeared in the spin-off novel The Shadows of Avalon by Paul Cornell, and Time Lord founder Rassilon was portrayed in several audio plays by black actor Don Warrington. Time Lords are extremely long-lived, routinely counting their ages in terms of centuries. It is not known how long a Time Lord can live, although the Doctor claimed in ...

Coffee - Coffee as a stimulant. Coffee contains caffeine, which acts as a stimulant. For this reason, it is often consumed in the morning, and during working hours. Students preparing for examinations with late-night "cram sessions" use coffee to maintain their concentration. Many office workers take a "coffee break" when their energy is diminished. Recent research has uncovered additional stimulating effects of coffee which are not related to its caffeine content. Coffee contains an as yet unknown chemical agent which stimulates the production of cortisone and adre ...

In almost all societies, death has one or several symbols associated with it. Common symbols of death in Western cultures include the grim reaper and the color black; conversely, in certain Eastern cultures, the color white is considered symbolic of death. The grave is a metonym for death. Biologically, death can occur to wholes, to parts, or to both. For example, it is possible for individual cells and even organs to die, and yet for the organism as a whole to continue to live; many individual cells live for only a short time, and so most of an organism's cells (except for nerve and muscle) are ...
