Sustained release of anti-inflammatory agents remains challenging for small molecule drugs due to their low molecular weight and hydrophobicity. Therefore, the goal of this study was to control the release of a small molecule anti-inflammatory agent, crystal violet (CV), from hydrogels fabricated with heparin, a highly sulfated glycosaminoglycan capable of binding positively-charged molecules s...

An ultraviolet spectrophotometric and a nonaqueous volumetric method for determining terbinafine hydrochloride (TH) in pharmaceutical formulations are presented. The UV spectrophotometric procedure was developed for assay of TH in raw materials, tablets, and creams. The method was tested for linearity (0.8-2.8 micrograms/mL, r = 0.9997), recovery (102.00% for creams and 99.90% for tablets) and ...

Screening for pathogenic Vibrio parahaemolyticus has become routine in certain areas associated with food-borne outbreaks. This study is an evaluation of the CHROMagar Vibrio (CV) medium-PCR protocol and the conventional method (TCBS (thiosulfate-citrate-bile salts-sucrose) agar plus biochemical and Wagatsuma agar tests) for detection of V. parahaemolyticus in shrimp, water, sediment, and stool...

In surface electromyography (surface EMG, or S-EMG), conduction velocity (CV) refers to the velocity at which the motor unit action potentials (MUAPs) propagate along the muscle fibers, during contractions. The CV is related to the type and diameter of the muscle fibers, ion concentration, pH, and firing rate of the motor units (MUs). The CV can be used in the evaluation of contractile properti...

Introduction SAHis one of the most common pathology in neurointensive care. There is a complication of SAHcerebral vasospasm (CV), which contributes significant mortality and morbidity. CV is believed to be the origin of Delayed Cerebral Ischemia (DCI). There are different methods to diagnose DCI and CV: neurological exam, MRI, CT, TCD and angiography, but they can’t detect ischemia on early st...

We evaluated the performance of a commercially available cellulose acetate electrophoretic method for quantitating high-density lipoprotein cholesterol (I) in serum by comparing it to a method involving precipitation with dextran sulfate-500/Mg2+. In both methods, enzymic reagents are used for cholesterol measurement. For electrophoretic measurement of I the mean intramembrane CV ws 4.1% (at 22...

In the literature it is suggested that the number of protest responses can depend on the valuation method. Choice Experiments (CE) are said to generate a lower number of protest responses than Contingent Valuation (CV). In a project about forest biodiversity both CE and CV were used and protest beliefs of all respondents irrespective of their willingness to pay determined. According to our anal...

We read with interest the paper of Marshall et al entitled 'Direct visualisation of collateral ventilation in COPD with hyper-polarised gas MRI'. 1 Collateral ventilation (CV) is defined as 'the ventilation of alveolar structures through passages that bypass the normal airway'. 2 This happens through the intra-alveolar pores of Kohn, the bronchio-loalveolar communications of Lambert and the int...
