BACKGROUND Mortality increases as ambient temperature increases. Because cocaine affects core body temperature, ambient temperature may play a role in cocaine-related mortality in particular. The present study examined the association between ambient temperature and fatal overdoses over time in New York City. METHODS Mortality data were obtained from the Office of the Chief Medical Examiner f...

BACKGROUND Determination of the plasma concentrations of arginine and other amino acids is important for understanding pathophysiology, immunopathology and nutritional supplementation in human disease. Delays in processing of blood samples cause a change in amino acid concentrations, but this has not been precisely quantified. We aimed to describe the concentration time profile of twenty-two am...

SAH after blood sample incubation over a period of 0, 2, 6, and 24 h at room temperature or at 4 °C. In the Primavette, Hcy obtained by HPLC decreased only slightly (Ϫ4.8%) after 6-h incubation at room temperature and returned to the baseline value after 24 h. At 4 °C a significant decrease of Hcy (6.9%) after 24-h incubation was found (P ϭ 0.003). Applying FPIA for the determination of Hcy, no...

The starch separated from 21 different Indian potato cultivars from four locations was evaluated for physicochemical, thermal and pasting properties. The relationships between the different properties of starches were determined using Pearson’s correlation analysis. Amylose content was positively correlated to hot paste viscosity (r = 0.460, P 6 0.05) and negatively correlated to transmittance ...

A study was conducted to determine the effects of water temperature and rations size on growth performance, feed utilization and carcass biochemical composition of juvenile Benni. Six treatments representing a combination of two water temperature (24 and 28 °C) and three feeding rations (1%, 3% and 5%) were tested with three replicates. Each replicate was stocked with 12 fish (30.66±0.81 g aver...

OBJECTIVE To evaluate the effect that maintaining tracheobronchial sputum at room temperature has on the analysis of ciliary transport and cough, as well as on the contact angle. METHODS Hyaline sputum was collected from 30 individuals without pulmonary diseases, and purulent sputum was collected from patients with bronchiectasis. The samples were analyzed immediately after collection and aga...

Rising water temperature associated with climate change is increasingly recognized as a potential stressor for aquatic organisms, particularly for tropical ectotherms that are predicted to have narrow thermal windows relative to temperate ectotherms. We used intermittent flow resting and swimming respirometry to test for effects of temperature increase on aerobic capacity and swim performance i...

The crystal structure of barbituric acid dihydrate (C4H4N2O3*2H2O) has twice been reported as orthorhombic, space group Pnma, with all atoms (except for CH(2) H atoms) lying on the mirror plane [Al-Karaghouli et al. (1977). Acta Cryst. B33, 1655-1660; Jeffrey et al. (1961). Acta Cryst. 14, 881-887]. The present study has found that at low temperatures, below 200 K, the crystal structure is no l...

Accurate models for electric power load forecasting are essential to the operation and planning of a power utility company. Load forecasting helps electric utility to make important decisions on trading of power, load switching, and infrastructure development. Load forecasts are extremely important for power utilizes ISOs, financial institutions, and other stakeholder of power sector. Short ter...
