background and aims. the aim of the present study was to compare the inhibitory effects of two systemic doses of hesa-a on prevention of 4-nqo-induced tongue neoplasms in rats. this study evaluated weight and histopathological changes. materials and methods. forty-eight male sprague dawley rats were divided into four groups of a, b, c and d of each 12 rats. the rats in groups b to d received 30...

Chrysin is a flavone that is found in several plants and in honeycomb and possesses various biological activities. However, its low solubility means it has poor bioavailability, which must be resolved to enable its pharmaceutical applications. In the present study, chrysin was incorporated into methoxy poly(ethylene glycol)-β-polycaprolactone nanoparticles (chrysin-NPs) using the oil-in-water t...

Sponge plastic is one of the wastes that difficult to degrade. Recently research reported Tenebrio molitor L larvae have potential capability degrade waste. But still a lack information according effect feed composition on survival, and growth T. larvae. The purpose this study was determine rate degradation sponge waste, method used in an experimental laboratory using Completely Randomized Desi...

background bronchopulmonary dysplasia (bpd) is one of the most common serious squeal of preterm infants. it involves approximately one quarter of infants with birth weight less than 1500 grams and 30% of less than 1000 grams. vitamin a has been shown to reduce bpd rate. we compared efficacy of low and high doses of vitamin a for prevention of bpd in very low birth weight preterm infants. materi...

The effect of essential fatty acids (EFA) and vitamin C-enriched Artemia nauplii on growth, survival, and resistance to temperature (high) stress in rainbow trout larvae reared in tanks were investigated. The larvae (average weight 120.43mg±13.5) were fed 6 times daily starting at the onset of exogenous feeding for 1 week. Triplicate groups of fish were offered one of four treatments (1) commer...

Tumors in female Swiss Millerton mouse skin were initiated with 25 pg 7,12-dimethylbenz(a)anthracene and, 2 weeks later, were promoted 3 times/week with 0.2 ml of 0.5% croton oil. Four steroid hormones in 0.2 ml of acetone were applied percutaneously at 6 and 30 jug 5 times/week. A fifth steroid was applied at the 30-^g dose. Tumor inhibition by the hormones was dose dependent in the order dexa...

We study the performance of a new block preconditioner for class \(3\times 3\) saddle point problems which arise from finite-element methods solving time-dependent Maxwell equations and some other practical problems. also estimate lower upper bounds eigenvalues preconditioned matrix. Finally, we examine our to accelerate convergence speed GMRES method shows effectiveness preconditioner.

Twelve male, sedentary volunteers (22.0 +/-) were submitted to three weeks of a bicycle ergometer training, consisting of 45 min exercise (at 70% VO2max), 4 times in the first week and 3 times in the next 2 weeks. They performed four incremental exercise tests with the power output increased by 50 W every 3 min until volitional exhaustion: two before training (C1 and C2), and after one (T1) and...
