Paraquat (PQ), as a highly effective and nonselective herbicide, induces cell apoptosis through generation of superoxide anions which forms reactive oxygen species (ROS). Mitochondria, as regulators for cellular redox signaling, have been proved to play an important role in PQ-induced cell apoptosis. This study aimed to evaluate whether and how mitochondrial fission interacts with oxidative str...
Effect of glutathione (GSH) depletion on paraquat (PQ) toxicity in the liver and kidneys of mice was examined. Glutamic-pyruvate transaminase (GPT) and blood urea nitrogen (BUN) levels in plasma of mice were hardly changed by treatment with 150 micro mol/kg of PQ. However, significant increases in the plasma GPT and BUN levels after PQ injection were observed in mice which were pretreated with ...
Paraquat (1,1'-dimethyl-4,4'-bipyridinium chloride, PQ) is a non-selective herbicide, and PQ poisoning by accidental or intentional ingestion is a cause of numerous fatalities around the world every year. Although a great deal of research has been conducted into the development of an acceptable treatment for PQ poisoning, no effective guidelines f...
زمینه: سنگ کلیه یک بیماری چند عاملی شایع در ایران است. عوامل محیطی و ژنتیکی از جمله چند شکلی های (پلیمورفیسم) تک نوکلئوتیدی در بروز سنگ کلیه تأثیر گذارند. هدف: مطالعه به منظور تعیین ارتباط چندشکلی t/c در نوکلئوتید ٤٠٦٥+ ناحیه غیرترجمه شونده 'utr٣ (′untranslated region٣) ژن اوروکیناز (rs) 4065 با احتمال ایجاد سنگ های کلسیمی کلیه انجام شد. مواد و روش ها: این مطالعه مورد- شاهدی در سال ۱٣۹۲ بر رو...
استهدف البحث الحالي تقصي الفروق في القدرة على حل المشكلات لدى طلاب المرحلة الثانوية تبعاً لبعض المتغيرات الديمغرافية (النوع – التخصص الدراسي نوع المدرسة)،
Multidrug and toxin extrusion 1 (MATE1/solute carrier 47A1) mediates cellular transport of a variety of structurally diverse compounds. Paraquat (PQ), which has been characterized in vitro as a MATE1 substrate, is a widely used herbicide and can cause severe toxicity to humans after exposure. However, the contribution of MATE1 to PQ disposition in vivo has not been determined. In the present st...
Paraquat (PQ) is a highly toxic herbicide which is able to induce pulmonary fibrosis in humans and animals. The epithelial‑to‑mesenchymal transition (EMT) was demonstrated to be an important factor in pulmonary fibrosis. However, it has remained elusive whether PQ induces pulmonary fibrosis via EMT, which was therefore investigated in the present study. In addition, the underlying mechanisms of...
Plasmodium vivax is the most prevalent of the five species causing malaria in humans. The current available treatment for P. vivax malaria is limited and unsatisfactory due to at least two drawbacks: the undesirable side effects of primaquine (PQ) and drug resistance to chloroquine. Phenylalanine-alanine-PQ (Phe-Ala-PQ) is a PQ prodrug with a more favorable pharmacokinetic profile compared to P...
Paraquat (N,N-dimethyl-4-4'-bipiridinium; PQ), a widely used herbicide, when ingested accidentally or intentionally can cause major organ toxicities in lung, liver, and kidney. Because PQ is primarily eliminated in the kidney, renal elimination, including tubular transport, plays a critical role in controlling systemic exposure to the herbicide. The goal of this study was to determine the molec...
To conduct a kinetic study of paraquat (PQ), we investigated 9 patients with acute PQ intoxication. All of them ingested more than 20 ml of undiluted PQ herbicide to commit suicide and arrived at our hospital early, not later than 7 h after PQ ingestion. The urine dithionite test for PQ in all of the nine patients was strongly positive at emergency room. Blood samples were obtained every 30 min...
