Hyperplasiais defined as an increase in tissue mass because of an increased number of cells. It may or may not be accompanied by hypertrophy of the same cells. In general,hyperplasiais the more efficient respons
“malignus,” and means malicious. Malignant neoplasms grow rapidly, and are locally invasive. Areas of necrosis seen in some malignant neoplasms presumably result when growth is so rapid that the neoplastic tissue outgrows the existingblood supply. Malignant growth is disorganized, and as such may...
In both mouse and humans, B cell hyperplasia is seen in many situations that involve T cell stimulation. In the mouse, some of these conditions appear to i
BPH andtestosterone.Testosterone is the main sex hormone in men and people assigned male at birth. This hormone acts on cells of the prostate and leads to the production of growth factors that make the prostate get bigger. As evidence of this effect, when men with prostate cancer take medicin...
Some studies indicate that the body’s system for working off testosterone slows in middle age. As a result, the body reacts by using this extra testosterone for the production of Dihydrotestosterone (DHT). High levels of DHT can cause enlarged prostate tissue growth. Diet Certain foods can ...
Etiology of prostatic growth demonstrates that prostate size increases slowly and steadily with aging.1 However, cause and effect links have not been established. The term "giant prostatic hyperplasia" was defined by Fishman and Merrill2 as exceeding 500 g. In this case, preoperative MRI ...
These cells subsequently serve as a source of SMCs that proliferate at the injured sites3,23. Notably, scavenger receptor-BI is closely linked to the role of rHDL10,24. In a study by Deiner et al., it was elucidated how the transfer of the VEGF gene into the adventitial region ...
it does so over a layer of platelets and fibrin that has been deposited on the thrombogenicbasement membrane. This nonocclusivethrombusis progressively organized into fibrotic tissue as the abundant platelet component releases growth factors, which promote ingress and proliferation of smooth muscle cells...
progressive growth that usually does not regress. Acollaretteof epithelium is defined as epithelium at the edge of a lesion, sometimes part of hyperplastic adnexal structures, that tends to bow inwardly and clutch alterations of thedermis. Examples of lesions that often have collarettes include liche...
Benign prostatic hyperplasia (BPH) is non-cancerous growth of the prostate gland which surrounds the urethra. For men with BPH who are older than 50, a prostatectomy is a common surgical procedure. Open prostatectomy is still more prevalent in regio
