We have studied the structural features of toxic chemicals from the RTECS database associated with specific toxicity. The frameworks, functional groups, and structure patterns of molecules are taken into account. Potential active frameworks, groups, and structure patterns for specific toxicity are gained by computational chemistry approaches. These structural features of toxic chemicals will be...
Purpose To report a rare presentation of the pericentral pattern of hydroxychloroquine (HCQ) retinal toxicity in a Caucasian female. Observations The patient presented with 20 years of exposure to HCQ, at a daily dose of 5.2mg/kg of actual body weight, and manifested a pericentral-only phenotype of HCQ toxicity, as demonstrated with detailed structural and functional testing. Conclusions an...
OBJECTIVE Capecitabine is an oral 5-fluorouracil (5-FU) pro-drug commonly used to treat colorectal carcinoma and other tumours. About 35% of patients experience dose-limiting toxicity. The few proven genetic biomarkers of 5-FU toxicity are rare variants and polymorphisms, respectively, at candidate loci dihydropyrimidine dehydrogenase (DPYD) and thymidylate synthase (TYMS). DESIGN We investig...
the toxicity of thiamethoxam and pirimicarb on diaeretiella rapae (mc'intosh) as a parasitoid of lipaphis erysimi (kaltenbach), exposed to residues on glass vials, was investigated under laboratory conditions at 23 ± 2 °c, 70 ± 5% rh and 16:8 h (l: d). moreover, in order to find the negative impacts of both insecticides on the efficiency of d. rapae, the functional response of the exposed paras...
Polymerizing the fibre between bacteria and host cells: the biogenesis of functional amyloid fibres.
Amyloid fibres are proteinaceous aggregates associated with several human diseases, including Alzheimer's, Huntington's and Creutzfeldt Jakob's. Disease-associated amyloid formation is the result of proteins that misfold and aggregate into beta sheet-rich fibre polymers. Cellular toxicity is readily associated with amyloidogenesis, although the molecular mechanism of toxicity remains unknown. R...
THEORETICAL AND EXPERIMENTAL STUDY OF STRUCTURE REACTIVITY RELATED TO METABOLISM TOXICITY PARACETAMOL. An experimental and theoretical approach on oxidative metabolism of paracetamol was applied for the pharmaceutical chemistry learning. Classical reactions, functional group identification, structural parameter, chemical reactivity using frontier orbitals Fukui index were used explaining main p...
teucrium polium l. (tp) is widely used in traditional medicine of many countries including iran. there are various reports about pharmacological properties of tp such as calcium antagonist, anti- ulcer, anti – diabetic. there are a few reports about possible toxicological effects of this plant. in the present study we designed to evaluate the subchronic toxicity of teucrium polium total extract...
