The mitotic index is a measure of cellular proliferation. [1] It is defined as the percentage of cells undergoing mitosis in a given population of cells. Mitosis is the division of somatic cells into two daughter cells. Durations of the cell cycle and mitosis vary in different cell types. An elevated mitotic index indicates more cells are dividing.
Cells in the mitotic phase are identified by the typical appearance of their chromosomes in the cell during the mitotic phase of the cell cycle. [4] Usually the number of mitotic figures is expressed as the total number in a defined number of high power fields, such as 10 mitoses in 10 high power fields.
In histopathology, the mitosis rate (mitotic count or mitotic index) is an important parameter in various types of tissue samples, for diagnosis as well as to further specify the aggressiveness of tumors. For example, there is routinely a quantification of mitotic count in breast cancer classification. [74]
The area provides a reference unit, for example in reference ranges for urine tests. [3]Used for grading of soft tissue tumors: Grading, usually on a scale of I to III, is based on the degree of differentiation, the average number of mitoses per high-power field, cellularity, pleomorphism, and an estimate of the extent of necrosis (presumably a reflection of rate of growth).
The downregulation of p130/E2F4 (a complex which has been shown to maintain the post mitotic nature of neurons) induces neuronal apoptosis by upregulating B-myb and C-myb (Liu et al., 2005). Cell cycle re-entry
The movie follows a group of high school students who create a fake university, the South Harmon Institute of Technology (S.H.I.T.), after being rejected by multiple colleges.
Health benefits: Studies indicate that drinking black tea may help reduce LDL (bad) cholesterol among people at high risk for cardiovascular disease, promote bone health, and improve mental alertness.
Separately, industry body UK Steel said any tariffs would represent a "devastating blow" to the sector, harming high-end steel exports to the U.S., which is Britain's second largest export market ...
