BACKGROUND Vitamin D status has been hypothesized to protect against development of diabetic retinopathy via its anti-inflammatory and anti-angiogenic properties. Additionally, in vitro and in vivo studies suggest vitamin D favorably influences blood pressure and blood glucose control, strong risk factors for diabetic retinopathy. We examined the association between vitamin D status and prevale...

BACKGROUND Solutions of vancomycin for oral administration are not available commercially in Canada or the United States but are needed for patients who cannot swallow capsules. OBJECTIVE To evaluate the stability of vancomycin solutions stored in unit-dose cups and plastic bottles under refrigeration (4°C) and at room temperature (25°C) for up to 75 days. METHODS Vancomycin 25 mg/mL in Ora...

Methods This study was performed in a referral allergist’s office in Ontario. Prospectively, all patients (<18 years old) with peanut allergy who were tested for peanut specific IgE (PN IgE) also had Vit D measured. All measurements were done between December 2010 and May 2011. The Vit D measure was 25-hydroxy vitamin D. Patients were divided into three groups: deficient (less than 25 nmol/L), ...

BACKGROUND We recently reported that antioxidant supplementation with vitamins C and E mitigated ozone related decline in forced expiratory flow (FEF(25-75)) in 158 asthmatic children in an area with high ozone exposure in Mexico City. METHODS A study was undertaken to determine whether deletion of glutathione S-transferase M1 (GSTM1 null genotype), a gene involved in response to oxidative st...

180 male students of 10+1&10+2 were tested on Rotter’s scale of locus of control and experimentally induced situations of probability of success by giving specific instructions. An Insoluble figure--‘perceptual reasoning task’ was used to test persistence of externally controlled Ss & internally controlled Ss in three experimental conditions i.e.P.25 (difficult task), P.50(intermediate task) &P...

Spirometric volumes and expiratory flows were measured among 448 Senegalese males and females of 25-80 yrs of age. The values obtained are similar to those reported for black Africans and black Americans in the literature. Volumes are 15-25% lower in males and 23% lower in females than in Caucasians. Forced expiratory flow between 25-75% of vital capacity (VC), (FEF25-75) is 5-18% lower in male...

OBJECTIVE To investigate the effect of force level and fatigue on brain activity during handgrip tasks. METHODS Electroencephalography (EEG) signals were recorded from eleven healthy male subjects when they performed 25%, 50% and 75% maximal voluntary contraction (MVC), and were in fatigue state. EEG powers in different handgrip tasks were analyzed in the frequency domain and time domain resp...

The aim of this study was to investigate the effectiveness of anaerobic digestion for the treatment of wool scouring wastes. The experiments design comprised three ratios of waste (W) to seed(S) (W:S) of 25:75, 50:50 and 75:25, corresponding to 1.9. 1.7 and 1.5g tCOD/g TS, respectively, with or without chemicals addition. NH4Cl was added to the reactors as a source for nitrogen to achieve C:N:P...

Los compuestos fenólicos encontrados en las plantas son antioxidantes naturales con beneficios biológicos para los seres humanos. El propósito de este estudio fue investigar cómo el solvente y la temperatura afectan extracción hojas fresa. Se evaluaron cinco tipos solventes (agua 100%, etanol metanol etanol:agua 75:25 metanol:agua 75:25) a tres temperaturas (40°C, 50°C 70°C). La combinación est...
