The purpose of this study was to investigate the effects two different acute stress protocols, such as restraint and cold stress, on coagulation indicators in rats. conducted 18 male Wistar albino rats aged 8-10 weeks with a body weight 180-220 g. After one-week adaptation period, were randomly divided into three groups (n=6/group). animals control group not exposed any stress. Rats housed rest...

BACKGROUND During continuous venovenous haemofiltration (CVVH), regional anticoagulation with citrate may be superior to heparin in terms of biocompatibility, since heparin as opposed to citrate may activate complement (reflected by circulating C5a) and induce neutrophil degranulation in the filter and myeloperoxidase (MPO) release from endothelium. METHODS No anticoagulation (n = 13), unfrac...

Obstacles to the widespread use of continuous renal replacement therapy (CRRT) include the need for anticoagulation, customized solutions, and complex protocols that carry an attendant risk for error, raise cost, and increase pharmacy and nursing workload. However, high solute clearance using CRRT with an effluent rate of 35 ml/kg per h has also recently been associated with improved survival i...

Silver colloidal nanorings have been synthesized by reducing silver ions with NaBH4 in trisodium citrate buffers. pH increase, by addition of NaOH, was used to speed up reduction reaction. The UV-vis absorption spectra of resulting silver nanorings showed two peaks accounting for transverse and longitudinal surface plasmon resonance, at ≈400 nm, and between 600 and 700 nm, respectively. The sha...

The four ingredients of ORS (glucose, sodium chloride, potassium chloride and trisodium citrate) in the concentrations described in the document entitled “Oral Rehydration Salts: a new reduced osmolarity formulation” yield an effective solution for rehydration and for the prevention of dehydration. The addition of other ingredients, such as other minerals (especially zinc) or vitamins, has not ...

Strong red upconversion luminescence of rare-earth ions doped in nanocrystals is desirable for the biological/biomedical applications. In this paper, we describe the great enhancement of red upconversion emission (4F9/2 --> I15/2 transition of Er3+ ion) in NaYF4:Yb3+, Er3+ nanocrystals at low doping level, which is ascribed to the effectiveness of the multiphonon relaxation process due to the e...
