Weeds represent a global agronomic problem that threatens the productivity of cultivated crops. Weeds compete with cultivated crops for the available moisture, nutrients and light. Consequently, weeds significantly reduce either crop yield or quality. Control of weeds is essential to maintaining the production of economic crops. Weed control may be achieved either through manual eradication or ...

Herbicides not only kill the weeds but also affect cell metabolism of economic crops, specifically their photosynthetic machinery [1]. They interfere with the development and structure of chloroplasts, thereby influencing light reactions of photosynthesis [2]. We report in this communication on the inter­ action of pyrazon, triazole and metribuzin with pea chloroplasts during greening in terms ...

background and aim: in skeletal muscle, carnitine plays an essential role in the translocation of long-chain fatty-acids into the mitochondrial matrix for subsequent beta-oxidation. despite an abundance of literature describing the basic mechanisms of action of l-carnitine metabolism, there remains some uncertainty regarding the effects of oral l-carnitine supplementation on metabolism and exer...

in this study the uptake and metabolism of adenosine by mitochondria has been investigated. incubation of cem cells mitochondria preparation with [3h] -adenosine showed substantial uptake and metabolism of adenosine. adenosine was both anabolized to amp, adp and atp, and also catabolized to inosine. the highest concentration of metabolites in extracted mitochondria was due to amp. the mitochond...

a digestion trial using cannulated lactating cows was conducted to evaluate the influence of barley grain processing on characteristics of ruminal fermentation and the site and extent of digestion. the experiment consisted in 4 periods and lasted 84 days. the total mixed rations contained 39.86% of grains and 42.90% of alfalfa hay and the rest of ration was composed mainly by cane molasses, fat...

objective(s):the aim of this study was to evaluate, for the first time, whether the effects of low-dose adropin administration is effective in rats with hyperlipidemia. materials and methods: twenty one wistar albino female rats were randomly divided into 3 groups and fed with high-fat diet for 4 weeks to establish the hyperlipidemia model. meanwhile, adropin was administrated intraperitonealy ...

With rapid economic development, most regions in southern China have suffered acid rain (AR) pollution. In our study, we analyzed the changes in sulfur metabolism in Arabidopsis under simulated AR stress which provide one of the first case studies, in which the systematic responses in sulfur metabolism were characterized by high-throughput methods at different levels including proteomic, genomi...

Current patterns and future possibilities of China's material metabolism are evaluated from perspectives of consumption structure change and technology development using the approach of input-output modeling to integrate ecological and economic systems. A physical input monetary output (PIMO) model is created and is applied to the Chinese economy with 43 sectors and 25 material categories. A se...
