Background: Epididymal spermatozoa have been used for production of offspring from genetically important animals after they are dead. To attain optimal fertility with epididymal spermatozoa, they should be preserved in a suitable medium in 37°C. Preservation media provides requirement for spermatozoa and affects its motility, viability, and fertility. Sucrose is one of the important components ...

Starting from 2,2'-dihydroxybiphenyl and an allenic ester, the title dibenzo-condensed dioxepine derivative was synthesized using a one-pot procedure.

Possessing putative hypolipidemic effects, Teucrium polium (TP) have been traditionally used as a medicinal plant in Iran. The aim of the present study was to investigate this effect on the sucrose-induced insulin resistance male rat model. Thirty Wistar male rats weighting 180 ± 20 g were divided into five groups of six each. Four groups were given sucrose 50% in drinking water for 10 weeks. I...

Sheep were used to determine the effects of dietary supplementation with readily-fermentable carbohydrates on Mg, Ca, K and P utilization. In each of two metabolism trials, 15 mature, crossbred wethers (average weight, 49.2 kg) were allotted to five dietary treatments consisting of 800 g/d of orchardgrass (Dactylis glomerata, L.) hay alone, or supplemented with 450 g/d of either glucose, sucros...

Niederpruem, Donald J. (Indiana University Medical Center, Indianapolis). Respiration of basidiospores of Schizophyllum commune. J. Bacteriol. 88:210-215. 1964.-The aerobic metabolism of basidiospores of the wood-rotting mushroom Schizophyllum commune was investigated by use of manometric techniques and specific respiratory poisons. Basal respiration was stimulated markedly by the uncoupling ag...

The utilization of deuteroacetate for the synthesis of ergosterol in an acetateless Neurospora mutant has been described in an earlier paper (1). In this work it was demonstrated that at least 25 per cent of the hydrogen atoms of ergosterol is derived directly from acetate. Since the use of deuterium as a tracer necessarily involves errors of unknown magnitude due to the lability of deuterium a...

A purification procedure for Neurospora crassa isocitrate lyase (ICL) is described. Thirteen mutants at the acu-3 locus produced no detectable ICL activity either on sucrose as sole carbon source or in the presence of acetate. These mutants also produced little or no protein able to neutralize anti-ICL antibodies. Selection of revertants, able to grow on acetate as sole carbon source, from one ...

Using freshly isolated maize mesophyll protoplasts and a transient expression method, I showed that the transcriptional activity of seven maize photosynthetic gene promoters is specifically and coordinately repressed by the photosynthetic end products sucrose and glucose and by the exogenous carbon source acetate. Analysis of deleted, mutated, and hybrid promoters showed that sugars and acetate...
