The Effect of Cold on Platelets. II. Platelet Function After Short-term Storage at Cold Temperatures

The effect of cold on platelets. II. Platelet function after short-term storage at cold temperatures.

Citrated platelet-rich plasma (PAP) was kept at cold temperatures or room temperature. After 4 hr or more at these temperatures, the PRPs were warmed 1 hr at 37#{176}C. This prevents the spontaneous aggregation seen in chilled PRP that is stirred immediately after warming. Platelet aggregation in response to connective tissue (CT), epinephrine, and adenosine diphosphate (ADP) was considerably g...

The Effect of Cold on Platelets

The effect of cold on platelet adenine nucleotide (PAN) metabolism was studied. Spontaneous aggregation which occurs when chilled platelet-rich plasma (PRP) is simultaneously warmed and stirred was not accompanied by the changes in adenine nucleotides associated with the release reaction. Connective tissue caused the release of the same amount of ADP and conversion of equal amounts of AlP to IM...

Effects of Harvest Date on Apple Fruit Quality at Harvesting and after Cold Storage

    Different dates for apples fruit harvest (Malus domestica Borkh. Cv. Fuji) were studied to determine physiochemical changes during the storage. Fuji apples were harvested from 9 September till 23 October, at five different times and stored at 0±0.5 °C and 95% relative humidity for 120 days. To determine the best harvest date for maximum quality and storability, physical and chemical paramet...

تاثیر گلیکوزیلاسیون برعملکرد و فاگوسیتوز پلاکت ها در طول نگهداری فرآورده پلاکت کنسانتره در سرما

Background and purpose: Cold storage results in clustering of gpIbα molecules on platelets. Consequently, the lectin domains of αMβ2 receptors on the liver macrophages recognize these molecules and ingest the platelets. Probably coverage of sugar molecules of gpIbα using galactose could prevent the recognition and ingestion of platelets by macrophages. The purpose of this study therby was to...
