There is large amounts of research focused on finding the specific enzymes and intracellular pathways involved in the NMDAR-mediated modulation of membrane AMPA receptors. Recent biochemical research has shown that a deficiency in the protein tenascin-R (TNR) leads to a metaplastic increase in the threshold for LTP induction. TNR is an ...
The metaplastic epithelium is at the junction (center of image) and has an intensely eosinophilic (bright pink) cytoplasm. H&E stain . Metaplasia (from Greek 'change in form') is the transformation of a cell type to another cell type. [ 1 ]
Metaplastic carcinoma, otherwise known as metaplastic breast cancer (MBC), is a heterogeneous group of cancers that exhibit varied patterns of metaplasia and ...
Common sites for squamous metaplasia include the bladder and cervix. Smokers often exhibit squamous metaplasia in the linings of their airways. These changes don't signify a specific disease, but rather usually represent the body's response to stress or irritation.
Micrograph of Barrett's esophagus (left of image) and normal stratified squamous epithelium (right of image). Alcian blue stain.. Glandular metaplasia is a type of metaplasia where irritated tissue converts to a glandular form.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Necrotizing sialometaplasia (NS) is a benign, ulcerative lesion, usually located towards the back of the hard palate.It is thought to be caused by ischemic necrosis (death of tissue due to lack of blood supply) of minor salivary glands in response to trauma.
Positions on an aromatic ring relative to the R group. In chemistry, meta is a prefix, used for systematic names in IUPAC nomenclature.It has several meanings. [1]In organic chemistry, meta indicates the positions of substituents in aromatic cyclic compounds.
