A bioluminescent method is presented that allows monitoring of ATP production from mitochondria corresponding to one islet of Langerhans per sample. In mitochondria from ob/ob mice Ca2+ stimulates the ATP production in the presence of L-glycerol 3-phosphate (GP) by reducing the Km for GP by one order of magnitude to about 3 mM. Maximal ATP production in the presence of Ca2+ (200 nM) is obtained...

grafting of cucurbitaceae species to some rootstocks seems to be especially beneficial for the nitrogen nutrition of these plants. moreover, melons (cucumis melo l.) have been considered among those plants that could benefit from the addition of silicon (si) in the nutrient solution (ns). thus, two experiments were carried out in the following order: (i) it was investigated how grafting affects...

in order to estimate the nutrient value of three dominant range species; festucaovina, trifolium montanum and alopecurus textilis via proximate analyses and gas productiontechnique, samples were collected in three stages during grazing period from 26th may to 1thseptember in six areas of sabalan mountain in north west of iran. results showed thattrifolium montanum as a legume had higher values ...

The gas extraction technological developments of the 2000s have allowed shale gas production, which in the US has become a significant part of the total gas production. Such a significant change might have affected the long-run relationship between oil and natural gas prices postulated by several authors. By using monthly data of oil and gas prices, as well as gas quantities from 1997 to 2013, ...

Background: Aflatoxins are fungal secondary metabolites negatively affecting ruminant performance; however, little information is available on their impact on rumen fermentation. Aims: This study aimed at determining the effects of different concentrations of aflatoxin B1 (AFB1) from Aspergillus flavus on in vitro gas production and ruminal fe...

In vitro gas production techniques simulate the rumen fermentation process and they have been used to evaluate the potential of feeds to supply nutrients to ruminants. Thus, effects of various levels of cobalt supplementation on gas production and rumen fermentation were investigated using an in vitro gas production technique. Ground samples (100 mg DM) of 70% wheat straw and 30% concentrate we...

The use of multiple populations in Genetic Programming is an area that is just beginning to be investigated. To date a number of conflicting reports have been generated with respect to the effectiveness of multiple populations in GP. We report here that these conflicting reports may be due a problem-dependent nature found in GP that has not been reported in GAs. This paper will review: what bot...

in an experiment, chemical composition, phenolics and fermentation parameters of different parts of raisin co-products (rc) were determined using in vitro gas production with or without polyethylene glycol (peg). different parts of rc included rejected raisins, pedicle, rachis, mixture of raisins, pedicle and rachis, and shekarak (a powder product obtained following sorting of raisins for packi...
