In dispersed acinar cells prepared from guinea pig pancreas, cellular uptake of 45Ca was moderately rapid and reached a steady state by 60 min. At the steady state, 69% of total cellular 45Ca was membrane-bound. In acinar cells preloaded with 45Ca and then incubated with COOH-terminal octapeptide of cholecystokinin (CCK-OP) or carbamylcholine, total cellular 45Ca decreased by approximately 40% ...

The present study was intended to investigate the different components of fatty acid utilization during a 60-min period of moderate-intensity cycling exercise (50% of VO2max) in eight male type 2 diabetic subjects (aged 52.6 +/- 3.1 years, body fat 35.8 +/- 1.3%) and eight male obese control subjects (aged 45.1 +/- 1.4 years, body fat 34.2 +/- 1.3%) matched for age, body composition, and maxima...

A 27-yr-old postgraduate student was found lying at the floor of an unsealed underground dry area, where a valve-opened empty cylinder of liquid nitrogen (150 L) was connected to a cap-removed empty Dewar-flask (10 L) via a copper infusion tube. No injury was found externally or internally. There were petechiae in the bilateral conjunctivae and periorbital skin. The dry area, measuring 300 x 13...

Two 21-d trials were conducted to evaluate the effect of heating time and sodium metabisulfite (SMBS) on the nutritional value of full-fat soybeans for chicks. In Trial 1, four pen-replicates of eight chicks each were fed corn-based diets (19% CP; 3,167 kcal of ME/kg) containing either 44% CP soybean meal or full-fat soybeans. The soybeans either were unheated or were autoclaved at 121 degrees ...

The effects of three different regimens of inhaled bronchodilators on spirometry and respiratory impedance as measured with the technique of forced oscillations were compared in a double-blind crossover study in 22 patients with stable chronic obstructive pulmonary disease (FEV1 less than 70 percent predicted). On three trial days, patients inhaled, in random order, 40 micrograms ipratropium br...

backgrounds and objectives: photocatalyst titanium dioxide nanoparticles can oxidize organic and inorganic compounds of microorganisms in aqueous solutions after exposure to uv light. in the present study, the inhibitory effect of titanium dioxide and its photocatalyst type on aspergillus flavus , escherichia coli and staphylococcus aureus is investigated.   materials and methods: toxicogenic s...

Manning’s roughness coefficient (nc) is an important parameter characterizing the flow capacity of water transfer channels, and it also sensitive in one-dimensional (1D) simulation. This study focused on inversion for datasets with different sequence lengths, time steps anomalous data points. A case was performed Shandong Jiaodong Water Transfer Project under steady-state conditions. For 6, 12,...

In the present work, time-variable modeling of high-energy mechanical grinding (0, 20, 30, 40, 50, 60, 70, and 80 min), was carried out to obtain best conditions process for obtaining modified starches with applications as wall materials favorable viscosity particle size characteristics nano-encapsulation bioactive compounds by means nano-spray drying. The pasting profile affected differen...

Sublethal heating, which can occur during slow cooking of meat products, is known to induce increased thermal resistance in Salmonella. However, very few studies have addressed the kinetics of this response. Although several recent studies have reported improved thermal inactivation models that include the effect of prior sublethal history on subsequent thermal resistance, none of these models ...
