Inhibition of nitric oxide synthase (NOS) activity in vivo impedes hypertrophy in the overloaded rat plantaris. We investigated the mechanism for this effect by examining early events leading to muscle growth following 5 or 12d of functional overload. Male Sprague-Dawley rats (~350g) were randomly divided into three treatment groups: Control, L-NAME (N-nitro-L-arginine methyl ester; 90mg/kg/d),...

The eusocial termites are well accomplished in chemical communication, but how they achieve the communication using trace amount of no more than two pheromone components is mostly unknown. In this study, the foraging process and trail pheromones of the fungus-growing termite Odontotermes formosanus (Shiraki) were systematically studied and monitored in real-time using a combination of technique...

introduction : constipation is one of the most prevalent causes of abdominal pain in pediatrics, with no underlying pathology. it is defined as functional constipation in 95% of cases evaluated. this study was designed to compare the therapeutic effect of polyethylene glycol (peg) and lactulose in treating chronic functional constipation in children. materials and methods: in this randomized, d...

Cis boleti (Coleoptera: Ciidae) preferentially colonizes fungi from the genus Trametes that are known as important wood decomposers. The aim of our research was to investigate if C. boleti uses the chemical volatile composition of its fungal host, Trametes gibbosa, as a key attraction factor. Therefore, the T. gibbosa fruiting body volatiles were analysed by using gas chromatography-mass spectr...

A solvent-free semihydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol was performed in a capillary reactor (10 m long, 0.53 mm i.d.) coated with a titania supported Pd-Bi catalyst. Several coatings with different Pd/Bi ratio have been prepared. The catalysts have been characterized with SEM, TEM, EDX, XRD analysis and N2 adsorption-desorption measurements. The maximum alkene ...

In the past decades, there has been great progress in development of organic and inorganic optical limiters with large nonlinear optical (NLO) response. Carbon-based materials, including carbon black suspension (CBS), singleand multi-walled carbon nanotubes (CNTs), 3] and some small p-electron systems, such as fullerenes, porphyrins, and phthalocyanines have been widely explored as advanced opt...

The dehydrogenation reaction of cholest-7-en-3beta-ol (I) to cholesta-5,7-dien-3beta-ol (II) in the presence of NADH was studied in rat liver microsomes and in microsomal acetone powder preparations, using [3alpha-3H]cholest-7-en-3beta-ol. It was found that the reaction was inhibited by menadione, adenosine diphosphate, potassium ferricyanide, and cytochrome c while p-cresol had no effect. Thes...

The crystal structure of the title compound, [PtCl(2)(C(25)H(22)NPS)]·0.5CH(2)Cl(2), was determined to establish the coordination properties of the (phosphan-yl)benzyl-idene-methanamine ligand to platinum. In the unit cell two mol-ecules of cis-[PtCl(2)(C(25)H(22)NPS)] are accompanied by a dichloro-methane solvent mol-ecule. The square-planar Pt(2+) coordination sphere is slightly distorted wit...

A study on Boletus edulis mushrooms subjected to either hot air drying (HAD) or centrifugal vacuum (CVD) was performed evaluate and compare their functional properties, fatty acids, aroma compounds. Better flowability a higher rehydration ratio were observed for HAD powders, while enhanced indices of water solubility, emulsifying activity, stability noticed CVD ones. The composition 21 identifi...

BACKGROUND Within- and between-person variation in nutrient intake is well established, but little is known about variability in dietary flavonoid intake, including the effect of seasonality. METHODS Within- and between-individual variability of flavonoid intake, and intake of flavonoid subclasses was examined in older adults (n = 79; mean age 70.1 y (range: 60y-80y)), using three separate 4-...
