Lack of sleep appears to negatively affect one's ability to appreciate and respond to increasing complexity, as was found in performance deficits after 1 night of sleep deprivation on a simulated marketing game. [27] The game involved subjects promoting a fictional product while getting feedback on the financial effects of their decisions.
Protein toxicity is the effect of the buildup of protein metabolic waste compounds, like urea, uric acid, ammonia, and creatinine.Protein toxicity has many causes, including urea cycle disorders, genetic mutations, excessive protein intake, and insufficient kidney function, such as chronic kidney disease and acute kidney injury.
Schematic overview of the classes of stresses in plants Neurohormonal response to stress. Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. [1] When stressed by stimuli that alter an organism's environment, multiple systems respond across the body. [2]
Once again, studies have shown a bidirectional nature between depressive symptoms and lack of sleep due to stress. Long-term/chronic psychosocial stress is known to cause depression symptoms but the effect of chronic stress on sleep can lead to a ripple effect of further damage including poor emotional stability, lowered attention span and self ...
Cortisol is a steroid hormone in the glucocorticoid class of hormones and a stress hormone. When used as medication, it is known as hydrocortisone. It is produced in many animals, mainly by the zona fasciculata of the adrenal cortex in an adrenal gland. [1] In other tissues, it is produced in lower quantities. [2]
The human data were confirmed, for the most part, by West et al. [21] using similar techniques and the same erythroleukemic target cell line, K562. K562 is highly sensitive to lysis by human NK cells and, over the decades, the K562 51 chromium-release assay has become the most commonly used assay to detect human NK functional activity. [22]
Edema results from a loss of fluid balance between the hydrostatic and oncotic pressures across the capillary blood vessel walls [2] due to the lack of protein which affects the body's ability to draw fluid from the tissues into the bloodstream. Low albumin concentration influences negatively the strength of oncotic pressure.
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors. Cell damage can be reversible or irreversible.
