The phyto-constituents and antioxidant activity of the fruit pulp of Trichosanthes cucumerina L. have not been reported in literature and were therefore studied. Two identified morphotypes of this plant (Morphotype I [V1] having long fruit with deep green background and white stripes; and Morphotype II [V2] having light green coloured long fruit) were used for the studies. The dry matter conten...

The aim of the present study was to find the effects of pre and post vitrification taxol treatment on bovineimmature cumulus oocyte complexes (COCs). Bovine ovaries were collected from the local slaughterhousein a container with 30-37°C physiologic saline and supplemented with antibiotics. The grade A aspiratedCOCs were assigned to 6 experimental groups; The 1st group was control (n=100) in whi...

background: exposure to arsenic is associated with impairment of male reproductive function by inducing oxidative stress. silymarin with an antioxidant property scavenges free radicals. objective: the aim of this study was to investigate if silymarin can prevent the adverse effects of sodium arsenite on ram sperm plasma membrane and acrosome integrity. materials and methods: ram epidydimal sper...

This study aimed to investigate the impacts of three organic acid salts and two bacterial additives on fermentation profile, in vitro digestibility gas production, aerobic stability total mixed ration (TMR) silage prepared with 10% fresh weight (FW) wet hulless barley distillers’ grains (WHDG), 35% FW common vetch, 15% whole-crop oat, straw, 30% concentrate. The (555 g kg?1 FW) was ensiled six ...

A HgCdTe e-APD detector has been developed for lidar receivers one application of which is integrated path differential absorption lidar measurements of atmospheric trace gases such as CO2 and CH4. The HgCdTe APD offers a wide, visible to MWIR, spectral response, high dynamic range, substantially improved sensitivity, and an expected improvement in operational lifetime. A demonstration sensor-c...

The first committed step in the biosynthesis of menaquinone (vitamin K2) is the conversion of chorismate to isochorismate, which is mediated by an isochorismate synthase encoded by the menF gene. This isochorismate synthase (MenF) is distinct from the entC-encoded isochorismate synthase (EntC) involved in enterobactin biosynthesis. MenF has been overexpressed under the influence of the T7 promo...

We have cloned genes encoding elongation factors EF-Tu and EF-Ts from Pseudomonas aeruginosa and expressed and purified the proteins to greater than 95% homogeneity. Sequence analysis indicated that P. aeruginosa EF-Tu and EF-Ts are 84% and 55% identical to E. coli counterparts, respectively. P. aeruginosa EF-Tu was active when assayed in GDP exchange assays. Kinetic parameters for the interact...
