In C. elegans, the loss of any of the three Trithorax proteins that catalyze the trimethylation of H3K4 such as, WDR-5 and the methyltransferases SET-2 and ASH-2, lowers the levels of H3K4me3 and increases lifespan. Loss of the enzyme that demethylates H3K4me3, RB-2, increases H3K4me3 levels in C. elegans and decreases their life spans. [13]
Exsanguination is the loss of blood from the circulatory system of a vertebrate, usually leading to death. The word comes from the Latin 'sanguis', meaning blood, [1] and the prefix 'ex-', meaning 'out of'. Exsanguination has long been used as a method of animal slaughter.
The role of cell death is the maintenance of tissue and organ homeostasis, for example, the regular loss of skin cells or a more active role seen in involuting tissues like the thymus. Cells die either by accident or design. In fact there are two mechanisms of cell death; necrosis and apoptosis (apoptosis in invertebrates is called cell ...
Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. [2] Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume).

Emaciation manifests physically as thin limbs, pronounced and protruding bones, sunken eyes, dry skin, thinning hair, a bloated stomach, and a dry or coated tongue in humans. Emaciation is often accompanied by halitosis , hyponatremia , hypokalemia , anemia , improper function of lymph and the lymphatic system , and pleurisy and edema .
Cole Prochaska lost 360 pounds by walking, eating a high-protein diet and lifting weights. But he feels trapped by his loose skin after his weight loss.
Aging is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death. The hallmarks of aging are the types of biochemical changes that occur in all organisms that experience biological aging and lead to a progressive loss of physiological integrity, impaired function and, eventually, death.
Linda Nolan's death was today announced on ITV's Loose Women as the panel paid a special tribute to the singer, describing her as a “'beacon of light. The TV star, best known for being one-fifth ...
