conclusions it seems that there is no difference in the use of heparinized and normal saline solutions to prevent catheter occlusion of arterial and central venous pressure. patients and methods in the current randomized controlled trial, 100 patients, with an age range of 18 - 65 years of valve and coronary artery surgery were studied in rajaie heart center, tehran, iran. patients were randomi...

objective: to assess the effect of heparin binding neurotrophic factor (hbnf) on sciatic nerve regeneration in animal model of rat. methods: seventy-five male wistar rats were divided into five experimental groups randomly (each group containing 15 animals): sham operation group (sham), autograft group (auto), transected control (tc), chitosan conduit (chit) and heparin binding neurotrophic fac...

objective: several studies have shown the improving effect of heparin on the outcomes of art. moreover, it has been reported that adding heparin in non-thrombophilia patients with rif is useful.the aim of this study was to evaluate the beneficial effects of heparin on art outcomes in women with history of recurrent implantation failure (rif) and without history of congenital or acquired thrombo...

Objective: Heparin and enoxaparin possess anti-inflammatory properties. We compared the effects of these drugs on inflammatory biomarkers in patients with ST-segment Elevated Myocardial Infarction (STEMI). Method: Thirty four patients with STEMI randomly separated in two groups and received standard doses of heparin and enoxaparin. The serum concentration of Serum Amyloid A (SAA), C-Reactive Pr...

Scalable architectures with non-uniform memory access time (NUMAs) have gained increased popularity in recent years. The increased scalability have increased the demand for scalable lock implementations, such as the queue-based locks of Mellor-Crummey and Scott (MCS lock), and of Craig, Landin and Hagersten (CLH lock). This paper demonstrates that the first-come first-served nature of queue-bas...

background: low molecular weight heparin (lmwh) is used for the treatment and prevention of coagulative disorders. few patients receiving therapeutic doses of lmwh develop major hemorrhage. currently there are few reports in the literature on acute overdose on adults.  in this study, clinical profile, treatment and outcome of 21 patients who acutely overdosed enoxaparin are described. methods: ...

The transition to multicore processors has brought synchronization, a fundamental challenge in computer science, into focus. In looking for solutions to the problem, interest has developed in the lock-free approach, which has been proven to achieve several advantages over the traditional mutual exclusion approach. This thesis studies challenges in interprocess synchronization in shared memory m...

A lock placement describes, for each heap location, which lock guards the location, and under what circumstances. We formalize methods for reasoning about lock placements, making precise the interactions between the program, the heap structure, and the lock placement.

The bone morphogenetic protein 6 (BMP6) is a crucial inducer of hepcidin, the peptide hormone that regulates iron availability in our body. Hepcidin expression influenced by hepatic heparan sulfate (HS) and heparin administration, suggesting BMP6 interaction with heparin/HS. BMP2/4 subfamily has been deeply characterized to have N-terminal heparin/HS binding domain (HBD), whose basic residues c...

abstract background: despite advances in the field of intravenous therapy, phlebitis is still a common complication of peripheral venous catheter and finding an appropriate solution to prevent and reduce the incidence of this complication remains challenging. one of the methods used in reducing the incidence of phlebitis is the use of saline lock, which is forgotten in most hospitals. therefore...
