Abstract Background: Thrombosis will occur due to contact of blood with unepithelialized surfaces after vascular clamping and also blood stasis during vascular surgery. Heparin is administered to prevent thrombosis. The aPTT test is used for assurance of the anticoagulative effect of heparin. At the end of the operation heparin is neutralized by protamine sulfate in some centers. In this study...

Heparin-induced thrombocytopenia (HIT) is characterized clinically by thrombocytopenia, hypercoagulability, and increased thrombosis risk, serologically platelet-activating anti-platelet factor 4 (PF4)/heparin antibodies. Heparin-“induced” acknowledges that HIT usually triggered a proximate immunizing exposure to heparin. However, certain non-heparin medications (pentosan polysulfate, hypersulf...

BACKGROUND Heparin solution is routinely used to maintain the patency of infusion devices. Literature supports the alternative use of normal saline solution for flushing and locking intravenous infusion devices especially for pediatric patients. There is uncertainty regarding safety and efficacy of this policy for intermittent locking of implanted ports. OBJECTIVE This study evaluates efficac...

Heparin was isolated from whole clam tissue Marcia opima . Purification of multimilligram quantities of heparin from this tissue sample permitted a thorough examination of its anticoagulant activity characterization, which was partially purified by fractionation by anion exchange chromatography using DEAE cellulose column. The isolated crude and partially purified fractionated sample showed me...

OBJECTIVE The objective was to increase the understanding of vascular access in hemodialysis and evaluate hemodialysis-related anticoagulation treatments and the associated hemorrhagic or thrombotic complications. MATERIALS AND METHODS In this study, an epidemiological investigation was conducted in 1175 patients who underwent hemodialysis in seven blood purification centers in northern Chine...

Locks are efficient concurrent control mechanisms to ensure that shared resources are accessed by only a single thread in multi-threaded applications. However, for multi-core systems, lock usage leads to lock contention, which degrades program performance, increases system response time, and negatively affects scalability. This paper initially models lock contention from two aspects: static str...

results the infusion group had a lower plasma pai-1 level compared to the subcutaneous group at day 7 (11.3 ± 1.6 vs. 16.5 ± 4.2; p = 0.003). the urinary ngal level was lower in the infusion group at day 2 (131.3 ± 11.9 vs. 151.2 ± 20.6; p = 0.014); however, at day 7 the ngal level was decreased in the subcutaneous group as much as the infusion group and there was no significant difference betw...
