A wide range of fatty acid esters can be synthesized by esterification and transesterification reactions catalyzed by lipases in non-aqueous systems. In the present study, immobilization of a purified alkaline extra-cellular lipase of Bacillus cereus MTCC 8372 by adsorption on diatomaceous earth (celite) for synthesis of ethyl acetate via transesterification route was investigated. B. cereus li...

A simple and rapid method is described for the isolation of the acidophilic and basophilic granules from the anterior pituitary gland of the rat. The method involves chromatography of pituitary particulates on columns of No. 545 Celite equilibrated and developed with 0.25 M sucrose. Mitochondria are retained quantitatively on the column. The granules and microsomes which are not retained on the...

UNLABELLED The monoclonal antibody fragment c7E3 Fab (ReoPro), by binding to platelet surface fibrinogen receptors (glycoprotein, GPIIb/IIIa), inhibits platelet aggregation and its interaction with fibrinogen. In this study, we used thromboelastography with ReoPro to evaluate the independent contribution of fibrinogen and platelets to clot strength. Thromboelastography was performed in 21 healt...

The mechanism by which negatively charged substances such as celite, kaolin, or ellagic acid contribute to the surface-dependent activation of Hageman factor (Factor XII) was studied. Kinetic studies of the proteolytic activation of (125)I-labeled human Hageman factor by human plasma kallikrein, plasma, activated Factor XI, and trypsin were performed in the presence and absence of high molecula...

UNLABELLED Thromboembolic events are a known complication in neurosurgical patients. There is evidence to suggest that a hypercoagulable state may develop perioperatively. Thrombelastograph (TEG) coagulation analysis is a reliable method of evaluating hypercoagulability. We evaluated coagulation by using TEG data in pediatric neurosurgical patients undergoing craniotomy to determine whether a h...

BACKGROUND The safety of human serum albumin (HSA) is of special interest with respect to virus transmission because of the wide use of this blood product as a therapeutic agent and also, added to other products, as an excipient or a stabilizer. Conflicting data are reported concerning HSA contamination by small, naked viruses such as the erythrovirus B19 (B19V) and the anellovirus torquetenovi...

High molecular weight genomic DNA was isolated from excised marrow cotyledons (Cucurbita pepo L., zucchini) using high concentration of ethidium bromide (400 μg.ml–1) in the grinding buffer and phenol deproteinization of the crude nuclear pellet. This preparation of DNA was free of proteins but contained polysaccharide contaminations which did not allow complete digestion with a number of restr...
