The Clearance Mechanism of Chilled Blood Platelets
Platelet transfusion is a very common lifesaving medical procedure. Not widely known is the fact that platelets, unlike other blood cells, rapidly leave the circulation if refrigerated prior to transfusion. This peculiarity requires blood services to store platelets at room temperature, limiting platelet supplies for clinical needs. Here, we describe the mechanism of this clearance system, a lo...
متن کاملMechanism of shape change in chilled human platelets.
The so-called cold activation of platelets that precludes refrigeration of platelets for storage has long been recognized, but its mechanism has remained a mystery. Cooling of discoid resting platelets to temperatures below 15 degrees C causes shape distortions, and the chilled cells rewarmed to above 25 degrees C are spheres rather than discs. As platelet shape change responsive to receptor ac...
متن کاملThe nutritive value of coconut toddy.
The partly fermented sap of the coconut palm (COCOS nucifera), called toddy in Malaya, is a popular drink among certain sections of the population in south-east Asia and among the natives of the central Pacific Islands. The methods of obtaining toddy from various species of palm have been described in detail by Gibbs (191 I ) and by Browning & Symons (1916), so that only a brief account need be...
متن کاملPotatoes: Source of Laboratory Reagent for Human Platelets Research
Irish potatoes is rich in carbohydrate, with varied glucose levels. It is also a very good source of apyrase, an enzyme used for platelet storage. The aim of this study was to explore Irish potatoes as an easily available source for apyrase extraction and purification. Apyrase was extracted from 5 Kg of Irish potatoes. Platelets were derived from 5-10 ml of human whole blood and G6PD activity w...
متن کاملCharacterization of alcohol resistant yeast Saccharomyces cerevisiae isolated from Toddy
In the present investigation Saccharomyces cerevisiae was isolated from Toddy and identified by based on morphological and sugar fermentation tests. In alcohol tolerance test, Saccharomyces cerevisiae tolerate up to 15% of ethanol in the medium. Optimize the culture conditions of yeast strain such as initial sugar concentration, pH, temperature and incubation period on ethanol production was al...
