The aim of metabolite profiling is to monitor all metabolites within a biological sample for applications in basic biochemical research as well as pharmacokinetic studies and biomarker discovery. Here, novel data analysis software, XCMS, was used to monitor all metabolite features detected from an array of serum extraction methods, with application to metabolite profiling using electrospray liq...

PURPOSE Magnetic Resonance Spectroscopy (MRS) of the prostate is not used in radiotherapy departments on a regular basis due to a number of issues. The indication and severity of prostate cancer is related to the presence of choline in the prostate, in particular, the ratio of choline (plus creatine) to citrate. In-vivo data supports this theory only marginally but lacks strong correlation with...

Discovering links between the genotype of an organism and its metabolite levels can increase our understanding of metabolism, its controls, and the indirect effects of metabolism on other quantitative traits. Recent technological advances in both DNA sequencing and metabolite profiling allow the use of broad-spectrum, untargeted metabolite profiling to generate phenotypic data for genome-wide a...

We already demonstrated that the modularity Q observed for the given metabolite classes is significantly higher than for a random association network (which we obtained by edge reshuffling, see main manuscript). In addition, we were interested in how closely the given metabolite classes represent an optimal partitioning of nodes in the network. Therefore we took a heuristic optimization approac...

We propose a new drug - "Rheoambrasol" which includes substance of plant origin (complex compounds polysaccharide and natural metabolite) non-toxic, environmentally friendly has wide functional capabilities as means capable correcting the consequences methemoglobinemia, restoring structural properties cells preserving their viability. The aim work is to study effect blood substitute on morpholo...

Despite the prevalence of migraine, the pathophysiology of the disease remains unclear. Current understanding of migraine has alluded to the possibility of a hyperexcitable brain. The aim of the current study is to investigate human brain metabolite differences in the anterior cingulate cortex (ACC) during the interictal phase in migraine patients. We hypothesized that there may be differences ...

Background: It has been shown that zinc has an effect on physiological responses in animals and birds. On the other hand, dietary phytase in poultry results in increased availability of zinc. OBJECTIVES: This study was conducted to investigate the effects of zinc oxide (ZnO) and Escherichia coli-derived 6-phytase supplemented diets on the plasma metabolites and enzyme activities of broiler bree...

Eleven patients underwent controlled ovarian hyperstimulation yielding 72 embryos for evaluation. Mean nitric oxide metabolite levels in the insemination media were 2.6 times higher in embryos that progressed to blastocysts by culture day 5 than in those that did not. A comparison of the receiver operating characteristic curves between morphological predictors and nitric oxide metabolite levels...

Loss-of-function Aspergillus nidulans CclA, a Bre2 ortholog involved in histone H3 lysine 4 methylation, activated the expression of cryptic secondary metabolite clusters in A. nidulans. One new cluster generated monodictyphenone, emodin and emodin derivatives, whereas a second encoded two anti-osteoporosis polyketides, F9775A and F9775B. Modification of the chromatin landscape in fungal second...
