Involution is the shrinking or return of an organ to a former size. At a cellular level, involution is characterized by the process of proteolysis of the basement membrane (basal lamina), leading to epithelial regression and apoptosis, with accompanying stromal fibrosis. The consequent reduction in cell number and reorganization of stromal ...
Many graduated students get involved in 996 working culture, like takeaway services, after they leave the universities. [11] Some of the picture shows takeaway drivers are trying their best to deliver food through Meituan (美团), a delivery-service corporation, with a high level of competitive business culture. [11]
Thymic involution is the shrinking of the thymus with age, resulting in changes in the architecture of the thymus and a decrease in tissue mass. [1] Thymus involution is one of the major characteristics of vertebrate immunology, and occurs in almost all vertebrates, from birds, teleosts, amphibians to reptiles, though the thymi of a few species of sharks are known not to involute.
Involution (medicine), the shrinking of an organ (such as the uterus after pregnancy) Neijuan, or involution, a Chinese social concept; Agricultural Involution, a 1963 study of intensification of production through increased labour inputs; Involution (esoterism), several notions of a counterpart to evolution
When the involution is impaired or retarded it is called subinvolution. The uterus is the most common organ affected by subinvolution. The uterus is the most common organ affected by subinvolution. As it is the most accessible organ to be measured per abdomen, the uterine involution is considered clinically as an index to assess subinvolution.
Basal chordates rely predominantly on invagination, anamniote vertebrates and reptiles on a varying combination of involution and ingression, and birds and mammals primarily on ingression. [ 6 ] Besides ingression, two other types of internalizing cell movements may occur during gastrulation: invagination and involution .
The first digit of the serial number represents the last digit of the year in which it was made, ranging from 7 (1987) to 4 (1994). [20] The USPS does not permit reselling LLVs, so when they are retired, they are scrapped for parts; [17]: 4–40 however, at least one was sold by the State of Georgia at auction in 2013. [21] [22]
