In chemistry, coprecipitation (CPT) or co-precipitation is the carrying down by a precipitate of substances normally soluble under the conditions employed. [1] Analogously, in medicine, coprecipitation (referred to as immunoprecipitation) is specifically "an assay designed to purify a single antigen from a complex mixture using a specific antibody attached to a beaded support".
The diathesis–stress model [23] emphasizes the importance of applying multiple causality to psychopathology, by stressing that disorders are caused by both precipitating causes, and predisposing causes. A precipitating cause is an immediate trigger that instigates a person's action or behavior. A predisposing cause is an underlying factor ...
Stress ulceration is a single or multiple fundic mucosal ulcers that causes upper gastrointestinal bleeding, and develops during the severe physiologic stress of serious illness. It can also cause mucosal erosions and superficial hemorrhages in patients who are critically ill, or in those who are under extreme physiologic stress, causing blood ...
Antioxidative stress is an overabundance of bioavailable antioxidant compounds that interfere with the immune system's ability to neutralize pathogenic threats. The fundamental opposite is oxidative stress , which can lead to such disease states as coronary heart disease or cancer.
Principle of chemical precipitation in aqueous solution. In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution".
Stress may be an important precipitating factor in the development of fibromyalgia. [62] A 2021 meta-analysis found psychological trauma to be strongly associated with fibromyalgia. [ 63 ] [ 64 ] People who suffered abuse in their lifetime were three times more likely to have fibromyalgia; people who suffered medical trauma or other stressors ...
A proximate cause is an event which is closest to, or immediately responsible for causing, some observed result. This exists in contrast to a higher-level ultimate cause (or distal cause) which is usually thought of as the "real" reason something occurred. The concept is used in many fields of research and analysis, including data science and ...
In clayey soil, bacteria are capable of reorienting and moving clay particles under low confining stress (at shallow depths). However, inability to make these rearrangements under high confining stresses limits bacterial activity at larger depths. Furthermore, sediment-cell interaction may cause puncture or tensile failure of the cell membrane.
