treat colon cancer. Hence, various multi-disciplinary choices are mandatory in order to provide patients with distended access to tailored treatments.Polycyclic aromatic hydrocarbons (PAHs) represent a class of widely distributed environmental pollutants that have been primarily studied as genotoxic compounds. Their mutagenicity/genotoxicity largely depends on their oxidative metabolism leading to production of dihydrodiol epoxide metabolites, as well as additional metabolites contributing to oxidative DNA damage, such as PAH quinones. However, both parental PAHs and their metabolites, including PAH quinones or hydroxylated PAHs, have been shown to produce various types of non-genotoxic effects. These include e.g. activation of the aryl hydrocarbon receptor and/or additional nuclear receptors, activation of membrane receptors, including tyrosine kinases and G-protein coupled receptors, or activation of intracellular signaling pathways, including mitogen-activated protein kinases, Akt kinase and Ca2+-dependent signaling. These pathways may, together with the cellular DNA damage responses, modulate cell proliferation, cell survival or cell-to-cell communication, thus contributing to the known carcinogenic effects of PAHs. In the present review, we summarize some of the known non-genotoxic effects of PAHs, focusing primarily on those that have been also shown to be modulated by PAH metabolites. Despite the limitations of the available data, it seems evident that a more attention should be paid to the discrimination between the potential non-genotoxic effects of parental PAHs and those of their metabolites. This may provide further insight into the mechanisms of toxicity of this large and diverse group of environmental pollutants.
The variability in drug response is highly complex and can be attributed to the polymedication, genetic polymorphisms modulating drug-metabolizing enzyme activities (cytochromes P450, CYP), physiological and environmental factors.” sentence could be revised as “The variability in drug response is highly complex and can be attributed to the polymedication, genetic polymorphisms modulating drug-metabolizing enzyme activities (cytochromeP450s (CYP)), physiological and environmental factors.

The main objective of this review is to deeply discuss the role of biotransformation in the occurrence of antidepressant and anticonvulsant induced inter individual variabilities with the focus on genetic variations and drug interactions.

An extensive search of the literature has been conducted related to biotransformation of the antidepressant and anticonvulsant agents on relationships between genetic differences and drug interactions on available databases. Following keywords are used for relevant articles “metabolic otential results of the drug-drug interactions and individual genetic characteristics should always be considered to make pharmacotherapy safer and more effective, as they have major clinical implications.
The present review clearly illustrates that interindividual differences in the biotransformation (including genetic variability of the drug metabolizing enzymes, age, sex, diet) of the antidepressant and anticonvulsant drugs, which are commonly prescribed medications globally, has a crucial role in the occurrence of adverse effects and various drug responses. Therefore, the potential results of the drug-drug interactions and individual genetic characteristics should always be considered to make pharmacotherapy safer and more effective, as they have major clinical implications.
Catalpol, an iridoid glycoside, is one of the richest bioactive components present in Rehmannia glutinosa. More and more metabolites of drugs have exhibit various pharmacological effects, thus providing guidance for clinical application. However, few researches have paid attention on the metabolism of catalpol.

This study aimed to establish a rapid and effective method to identify catalpol metabolites and evaluate the biotransformation pathways of catalpol in rats.

In this study, catalpol metabolites in rat urine, plasma and faeces were analyzed by UHPLC-Q-Exactive MS for the characterization of metabolism of catalpol. Based on high-resolution extracted ion chromatograms (HREICs) and parallel reaction monitoring mode (PRM), metabolites of catalpol were identified by comparing the diagnostic product ions (DPIs), chromatographic retention times, neutral loss fragments (NLFs) and accurate mass measurement with those of catalpol reference standard.

A total of 29 catalpol metabolites were detected and idenhich phase Ⅰ and phase Ⅱ reactions occurred. However, hydrophilic chromatography-mass spectrometry still needed to further find the polar metabolites of catalpol.
CsaA is among the few chaperones which are present in both bacteria and archaea, but absent in eukaryotes. There are no reports on interactome analysis of CsaA from archaea, till date. selleck inhibitor Identification of binding partners of CsaA might be helpful in understanding CsaA-associated processes in Picrophilus torridus- an extreme thermoaci-dophilic euryarchaeon.

The present study was conducted to identify the binding partners of CsaA of P. torridus (PtCsaA).

The binding partners of PtCsaA were isolated and identified using a pull down assay and liquid chromatography-mass spectrometry (LC-MS).

The results revealed twelve potential binding partners of CsaA. These were thermosome subunits (Q6KZS2 and Q6L132), nascent polypeptide-associated complex protein (Q6L1N3), elongation factor 1-alpha (Q6L202), uncharacterized protein (Q6L0Y6), citrate synthase (Q6L0M8), asparaginyl-tRNA synthetase (Q6L0M5), succinyl-CoA synthetase beta chain (Q6L0B4), pyruvate ferredoxin oxidoreductase alpha and beta chain proteins (Q6KZAof CsaA-associated processes in archaea.Diabetes mellitus (DM) and peripheral artery disease (PAD) are two clinical entities closely associated. They share many pathophysiological pathways such as inflammation, endothelial dysfunction, oxidative stress and pro-coagulative unbalance. Emerging data focusing on agents targeting these pathways may be promising. Moreover, due to the increased cardiovascular risk, there is a growing interest in cardiovascular and "pleiotropic" effects of novel glucose lowering drugs. This review summarizes the main clinical features of PAD in patients, the diagnostic process and current medical/interventional approaches, ranging from "classical treatment" to novel agents.
