The dimeric η(6)-hexamethylbenzene ruthenium(II) triazole compounds of formulation [{(η(6)-C(6)Me(6))Ru(N(3)C(2)(CO(2)R)(2))}(2)(μC(2)O(4))] have been synthesized by 1,3-diploar cycloadditions of coordinated azido compound [{(η(6)-C(6)Me(6))Ru(L(1))N(3)}] (1) with substituted acetylene, RO(2)CC(2)CO(2)R via unexpected oxidation of the coordinated ligand to oxalate (where; L(1) = 5-hydroxy-2-(hy...

Cofacial Fe2, Co2, and Ni2 complexes supported by a para-terphenyl diphosphine ligand were prepared. Central arene deplanarization and a μ2:(η(3),η(3)) coordination mode suggest partial bisallyl character in the Fe2 and Co2 complexes. An oxidation induced shift in Fe2-arene binding highlights the non-innocent nature of the arene ligand.

The in vitro activity of a series of ruthenium clusters, [(g-C6H6)(g -C6Me6)2 Ru3(l-H)3(l3-O)][BF4], [(g -C6H6)(g -1,4-PrC6H4Me)(g -C6Me6)Ru3(l-H)3(l3O)][BF4], [(g -C6H6)4Ru4(l-H)4][BF4]2, [(g -C6H5Me)4Ru4(l-H)4][BF4]2 and [(g-C6H6)4Ru4(l-H)3(l-OH)][Cl]2, has been evaluated against A2780 and A2780cisR ovarian carcinoma cell lines. Both triruthenium clusters are very active compared to ruthenium...

The liver fulfills many vital functions for the body, among them bile formation and detoxification. Bile salts are organic anions, major constituents of at high concentrations cytotoxic. Detoxification exposes to harmful compounds. This function is therefore potentially damaging liver. Impaired may lead hepatic accumulation subsequently disease. Diagnosis diseases involves measurement so-called...

background illicit opiate use has an increasing incidence and prevalence, which increases mortality and morbidity, marginalization, and criminal behaviors, and causes major adverse effects on society. objectives this study aimed to investigate and follow the outcome of patients who underwent ultrarapid opiate detoxification (urod) prospectively. patients and methods in this randomized clinical ...

Chronic benzodiazepine (BDZ) abuse is currently treated with detoxification using a low-dose flumazenil infusion, a relatively recently developed and promising procedure. Given the possibility reported in the literature of the occurrence of generalized seizures during therapeutic BDZ detoxification, we usually administer preventive antiepileptic drug (AED) therapy. We describe two patients with...

In 2009, pyrethroid resistance was confirmed for seven "annual bluegrass weevil" Listronotus maculicollis Kirby (Coleoptera: Curculionidae) adult populations from southern New England. The mechanisms responsible for conferring this resistance were unknown. In this study, topical application bioassays with bifenthrin and bifenthrin combined with synergists affecting three detoxification systems ...

Formaldehyde is the simplest of all aldehydes and is highly cytotoxic. Its use and associated dangers from environmental exposure have been well documented. Detoxification systems for formaldehyde are found throughout the biological world and they are especially important in methylotrophic bacteria, which generate this compound as part of their metabolism of methanol. Formaldehyde metabolizing ...

ZBTB3 belongs to the Zinc finger and BTB/POZ domain containing transcription factor family; however, its biological role has rarely been studied. We demonstrate for the first time, to our knowledge, that ZBTB3 is an essential factor for cancer cell growth via the regulation of the ROS detoxification pathway. Suppression of ZBTB3 using two different short hairpin RNAs in human melanoma, lung car...
