A peg cell is a non-ciliated epithelial secretory cell within the uterine tube (oviduct or fallopian tube). [1] These cells represent one of three epithelial cell types found within the normal fallopian tube epithelium and only make up around 10% of the total number of cells. The other two cell types are ciliated columnar and intercalary cells. [1]
PEG is the basis of many skin creams (as cetomacrogol) and personal lubricants. PEG is used in a number of toothpastes [5] as a dispersant. In this application, it binds water and helps keep xanthan gum uniformly distributed throughout the toothpaste. PEG is under investigation for use in liquid body armor, and in tattoos to monitor diabetes. [33]
It is also used in the treatment of certain T-cell lymphomas, particularly mycosis fungoides. [citation needed] Peginterferon alfa-2a is a long acting interferon. Interferons are proteins released in the body in response to viral infections.
There are three different cell types in the epithelium. Around 25% of the cells are ciliated columnar cells; around 60% are secretory cells, and the rest are peg cells thought to be a secretory cell variant. [4] The ciliated cells are most numerous in the infundibulum, and the ampulla. Estrogen increases the formation of cilia on these cells.
Polyethylene glycol. PEGylation (or pegylation) is the process of both covalent and non-covalent attachment or amalgamation of polyethylene glycol (PEG, in pharmacy called macrogol) polymer chains to molecules and macrostructures, such as a drug, therapeutic protein or vesicle, which is then described as PEGylated.
The apical surface of the uterine epithelial cells is covered with microvilli that are under hormonal control and vary in length and number with the oestrous cycle and during pregnancy. A hormonally dependent glycocalyx is found outside the microvilli [ 2 ] while the center of the microvilli consists of an actin filament core which is embedded ...
Macrogol 4000, pharmaceutical quality. Macrogol 3350, often in combination with electrolytes, is used for short-term relief of constipation as well as for long-term use in constipation of various causes, including in multiple sclerosis and Parkinson's disease patients (an often-overlooked non-motor symptom) as well as constipation caused by pharmaceutical drugs such as opioids and ...
Pegfilgrastim is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in people with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia; and to increase survival in people acutely exposed to myelosuppressive doses of radiation (hematopoietic subsyndrome of acute ...
