Background: The well-known toxic effects of benzene toxicity are bone marrow depression, reduction in blood cell counts, and induction of leukemia and aplastic anemia. This study was designed to evaluate biomarkers of aging in red blood cells (RBCs). Methods: Mice were exposed to benzene (50, 100, and 200 mg/kg/day) orally for 28 days. A group of benzene-exposed mice were injected intraperiton...

An efficient enantioselective synthetic method for the synthesis of (2R)-5-phenyl-2-alkylproline tert-butyl esters was reported. The phase-transfer catalytic alkylation of tert-butyl-5-phenyl-3,4-dihydro-2H-pyrrole-2-carboxylate in the presence of chiral quaternary ammonium catalysts gave the corresponding alkylated products (up to 97% ee). The following diastereoselective reductions afforded c...

Alkylation of T7 bacteriophage considerably delayed phage development and reduced the phage's killing action on host cells. Only a small fraction of infected cells produced phage. For these phages, the latent period was markedly prolonged but the burst was equivalent to or only slightly lower than that of untreated phage. In the progeny of alkylated phage, there was an increase in the fraction ...

In this study, B12N12 Nano ring has been selected because it consist of four 6-side rings and polar bonds B-N which in comparison with non-polar bonds C-C, is more suitable for the study of the absorption of other compounds. So reactivity and stability of Benzene alone and in the presence B12N12 nano ring field checked. To determine the non-bonded interaction energies between Benzene and B12N12...

Eosinophilic inflammation in chronic obstructive pulmonary disease (COPD) is predictive for responses to inhaled steroids. We hypothesised that the inflammatory subtype in mild and moderate COPD can be assessed by exhaled breath metabolomics. Exhaled compounds were analysed using gas chromatography and mass spectrometry (GC-MS) and electronic nose (eNose) in 28 COPD patients (12/16 Global Initi...

This communication introduces a new class of self-assembling organogelators composed of a double chain-alkylated L-glutamide with a polymeric head group.

In both the inorganic and organic worlds, carbon-based nanomaterials, such as benzene, diamond, graphite, fullerene, carbon nanotubes, are abundant. science laboratories, is focal point of activity. this overview, synthesis, characteristics, several uses graphene—including energy conversion, storage, electronics, biosensing—were explored with a focus on ecologically friendly production techniqu...

background: several effects of volatile organic compounds (vocs) have been recognized such as toxic and carcinogenic human health effects. to evaluate cancer risk of benzenes air samples were taken, at an automobile manufacturing painters in tehran following inhalation exposure. methods: to perform this study, cross-sectional was done in 2016. sampling was carried out by active pump sampler usi...
