Antithrombin (AT) is the key inhibitor, which controls the action of these enzymes in hypercoagulable states. The AT concentrates prepared from human blood have been used to treat patients with thrombotic disorders and heparin resistance. The AT concentrates are prepared from pooled human plasma and beside limited supply, suffer from viral and other biological contaminants. The availability of recombinant human AT (rhAT) obtained from genetically engineered goats provide a biologically equivalent product that can be used in practically all indications where human AT is indicated including heparin resistance. Moreover,

because of its CHIR-99021 concentration high affinity to heparin and related drugs, BMS-754807 recombinant AT can also be developed in further indications. On review of the preclinical and

clinical data on the safety and efficacy, the European Union and U.S. Food and Drug Administration (US-FDA) have recently approved the use of rhAT in specified clinical indications.”
“Semi-1 and semi-2 interpenetrating polymer networks (IPNs) of poly(vinyl chloride) (PVC) and in situ formed poly(ethyl acrylate) (PEA) have been synthesized using diallyl phthalate and ethylene glycol dimethacrylate as the crosslinkers of PVC and PEA, respectively. These two types of IPNs have been compared with respect to their physical, mechanical, and thermal properties and an endeavor has been made to find a correlation of these properties this website with the morphology generated in these systems. The semi-1 IPNs displayed a decrease in their tensile strength and modulus while in contrast; the semi-2 IPNs exhibited a marginal increase with increasing crosslinked PEA incorporation. The semi-l and semi-2 IPNs containing 10 and 30 wt % of PEA displayed a two-stage degradation typical of PVC in their thermogravimetric and DSC studies while confirming the increased stability of the samples

with higher percentages of PEA. The softening characteristics as detected by the extent of penetration of the thermomechanical probe as has been detected by thermomechandica; analysis are in conformity with their mechanicals. The biphasic cocontinuous systems as explicit from the morphological studies reveal fibrillar characteristics in both the systems. (C) 2009 Wiley Periodicals, Inc.

“BACKGROUND Surgical skin flaps are useful, but flap necrosis is a common problem. Epigallocatechin gallate (EGCG), the major polyphenol of green tea, has been investigated as a neovascularization agent to counteract necrosis.

OBJECTIVES To evaluate the effect of EGCG on random pattern skin flap survival.

MATERIALS AND METHODS The rat dorsal skin flap model was employed. One hundred rats were divided into five groups of equal size.
