<strong><em>ABSTRACT</em></strong> <em>A xenobiotic is a </em><em>chemical which is found in an organism but which is not normally produced or expected to be present in it. It can also cover substances which are present in much higher concentrations than are usual. This study deals with the analysis of xenobiotics in detail including the concepts like Xenobiotic Metabolism(Xenobiotic Biotransformation), Rapid analysis of pharmaceuticals and excreted xenobiotic and endogenous metabolites with atmospheric pressure infrared MALDI mass spectrometry , De

Seasonal changes in the mineralization of mixed amino acids (MAA), an anionic surfactant (linear alkylbenzene sulfonate; LAS), a detergent builder (nitrilotriacetic acid; NTA), and a herbicide (2,4-dichlorophenoxyacetic acid; 2,4-D) by microbial communities were studied in two streams in southwestern Ohio. Radiolabeled (14C) test compounds were added to samples of seston, leaf litter, periphyton, and sediment collected from Briarly Creek, a waste water impacted stream, and Little Indian Creek, a relatively unimpacted stream. Mean values for NH3, orthophosphate, dissolved organic carbon, and to

Liver is considered as the first target for the toxic effects of toxins and other xenobiotics, and this can be attributed to its role as a site which receive all absorbed xenobiotics from the gastrointestinal tract and its role as a major site for biotransformation of xenobiotics. The present study was designed to evaluate the possible hepatoprotective effect of benfotiamine against CCl4-induced hepatotoxicity in rats. The study was conducted on 48 male albino rats; the animals were allocated into 8 groups (6 rats in each group) and treated as follow: 4 groups treated with oral doses of either

When incubated alone for 7 days with the fungus Cunninghamella echinulata, tranylcypromine was extensively metabolized. As observed in mammalian systems, N-acetyltranylcypromine was the major metabolite recovered along with lesser amounts of 4-hydroxytranylcypromine, as its N,O-diacetyl derivative. The rate and extent of tranylcypromine biotransformation was affected by whether incubation was on either 30° or flat brackets with a gyratory shaker. There is a strong association between the rate of biotransformation and the utilization of glucose, formation of ammonia, and pH. The slowest rates o

The anthropogenic impact on the biosphere has now acquired a global character, resulting in a massive inﬂux of industrial, agricultural, and household waste into the environment. Numerous chemical, physical and biological substances present in the environment have a harmful effect on human health. Among them, a special group is formed by hormonally active xenobiotics – xenoestrogens. They are not produced by the body, but are structurally or functionally related to the human sex hormone 17β-estradiol, and bind to estrogen receptors with varying degrees of afnity and selectivity.

The environment pollution or contamination is a serious problem, a great deal of research is being undertaken to combat contaminants such as xenobiotic and recalcitrant compounds, particularly heavy metals, dyes,phenolic compounds and other recalcitrant pollutants produced by a wide range of industrial activities. These compounds have an adverse impact on the environment, particularly when generated by industrial processes and then disposed off without adequate treatment. Mycoremediation is defined as the use of fungi for bioremediation, especially degradation or retention of contaminants. Bio

<em>The basic objective of the present investigation is to study the enzymatic pre-treatment as alternative physicochemical methods, for enhancing the biodegradability of aromatic dye compounds and was found to be more effective (Alexander et al., 1997). Horseradish peroxidase was extracted and studies for azo degradation at batch scale. The batch studies performed to study the process parameters during azo dye degradation revealed, effect of repeated application of alginate immobilized enzyme on dye degradation as 52%removal of dye in first batch which was reduced to 22.2%in the fifth batch .

Two Gram-positive coryneform bacteria that degraded p-chlorophenol isolated from a continuous culture system are characterized. Isolate B (probably an Arthrobacter sp.) completely removed the p-chlorophenol from a medium with a concomitant increase in cell density within 16 h. Isolate F similarly removed the p-chlorophenol within 28 h but without an increase in cell density. Isolates B and F also removed the p-chlorophenol from a medium with p-chlorophenol as the sole carbon source within 32 and 48 h, respectively. The optimal temperature for p-chlorophenol degradation by both organisms was 25

Solid-state 13C CPMAS NMR offers many options for characterizing carbon in soil organic matter (SOM). Its effectiveness, however, is often limited by a poor understanding of the techniques, and lack of hands-on access and training opportunities for students. Of nearly 250 modern NMR systems in Canada, approximately one is genuinely available for SOM studies, and there is poor communication between NMR operators and SOM users. While quantitative reliability can be addressed to some extent by multiple contact-time experiments or single-pulse (Bloch decay) spectra, it is also important to conside

Resume. Many studies have shown that an important factor in the health of the human body is the state of the environment. The aim of this work is to review the literature on the study of the effects of xenobiotics on dental morbidity. The highest rates of prevalence and intensity of periodontal disease were found in regions with high and very high levels of environmental pollution, the lowest – in a region with relatively low total levels of environmental pollution. Children living in environmentally unfavorable areas have a significant number of somatic diseases, which are combined with high
