BACKGROUND Platelet hyperaggregability is a pro-thrombotic feature of type-2 diabetes, associated with low levels of the antioxidant glutathione (GSH). Clinical delivery of N-acetylcysteine (NAC), a biosynthetic precursor of GSH, may help redress a GSH shortfall in platelets, thereby reducing thrombotic risk in type-2 diabetes patients. We investigated the effect of NAC in vitro, at concentrati...

A recent whole organ study in cat skeletal muscle showed that the increase in venous resistance seen at reduced arterial pressures is nearly abolished when the muscle is perfused with a nonaggregating red blood cell suspension. To explore a possible underlying mechanism, we tested the hypothesis that red blood cell aggregation alters flow patterns in vivo and leads to blunted red blood cell vel...

Objective: To study plants purification capability of  Cu on two cultivars of vetch plant (Vigna Radiata) in contaminated soils and their effects on morphological characteristics. Methods: we conducted a completely randomized trial as factorial. Different concentrations of  Cu (0, 150, 300, and 400 mg/ Kg of dried soil) were used. After four weeks growth on contaminated soil, parameters such as...

The study on the flow behave inside of a ball valve is important for heavy crude oil transportation. Owe to the fast progress of the numerical technique, it becomes an effective way to observe the flows inside a valve and to analyze the flow structure of the oil-water core annular flow. In the present study, the simulation of the oil-water core annular flowing through the valve is conducted...

BACKGROUND Flavonoids may be partly responsible for some health benefits, including antiinflammatory action and a decreased tendency for the blood to clot. An acute dose of flavanols and oligomeric procyanidins from cocoa powder inhibits platelet activation and function over 6 h in humans. OBJECTIVE This study sought to evaluate whether 28 d of supplementation with cocoa flavanols and related...

objective: to identify the proportion and some selected characteristics of juvenile diabetics attending birdem hospital. materials and methods: this was a cross sectional study. the study was conducted in the birdem hospital. all diabetic young aged up to 18 years who visit birdem hospital were included in study population. the sample size was 240. results: it was observed that among the respon...

An important issue in P2P networks is the existence of malicious nodes that decreases the performance of such networks. Reputation system in which nodes are ranked based on their behavior, is one of the proposed solutions to detect and isolate malicious (low ranked) nodes. Gossip Trust is an interesting previously proposed algorithm for reputation aggregation in P2P networks based on t...

<p class="abstrak">Gold nanoparticle (AuNP) is a material commonly used in colorimetric detection for biological sensors due to its low production cost, simplicity, and ease use. AuNP known generate different colors depending on the particle aggregation level. In last two decades, changes status have become basis developing sensor detect analytes sample. The solution color could be observ...

liquid protein formulations are prone to form aggregates. the effect of nonionic surfactants such as polysorbate 20 (ps 20) and n-dodecyl β-d-maltoside (ddm) on the prevention of aggregation and conformational changes of recombinant human ifnβ-1b (rhifn β_1b) was explored. polysorbate has been used in formulations of protein pharmaceuticals. there have been concerns about using ps 20 due to its...
