Hexavalent Chromium [Cr(VI)] compounds are human lung carcinogens and environmental/occupational hazards. The molecular mechanisms of Cr(VI) carcinogenesis appear to be complex and are poorly defined. In this study, we investigated the potential role of Gene 33 (ERRFI1, Mig6), a multifunctional adaptor protein, in Cr(VI)-mediated lung carcinogenesis. We show that the level of Gene 33 protein is...
Selenium (Se) is a contaminant in effluents from coal mines and coal-fired power stations, where it is encountered as the oxyanion selenate (SeO4(2-), hereafter Se(VI)). Se(VI) can be removed from solution with Fe-treated biosorbents, but the efficacy of these treatments in effluents with multiple contaminants is unclear. This study investigates the interactions between Se(VI) and the oxyanions...
experiments, for aqueous Cr(VI) solutions having low buffering capacities, over the Cr(VI) concentration range of 5 – 40 mg/L. The results showed that the initial Cr(VI) concentration significantly affects the reduction capacity of scrap iron. Maximum reduction capacity of scrap iron was observed at the beginning of the column experiments; the lower the Cr(VI) concentration, the greater the exp...
Collagen VI and WARP are extracellular structural macromolecules present in cartilage and associated with BM suprastructures in non-skeletal tissues. We have previously shown that in WARP-deficient mice, collagen VI is specifically reduced in regions of the peripheral nerve ECM where WARP is expressed, suggesting that both macromolecules are part of the same suprastructure. The object of this s...
Expression of myosin VI within the early endocytic pathway in adult and developing proximal tubules.
Myosin VI is a reverse-direction molecular motor implicated in membrane transport events. Because myosin VI is most highly expressed in the kidney, we investigated its renal localization by using high-resolution immunocytochemical and biochemical methods. Indirect immunofluorescence microscopy revealed myosin VI at the base of the brush border in proximal tubule cells. Horseradish peroxidase up...
In the present work, we investigated the multielemental elution behavior of metal ions absorbed on iminodiacetic acid (IDA) chelating resin by using hydrogen peroxide (H(2)O(2)) as an eluent. As a result, V(V), Mo(VI), W(VI), Nb(V) and Ta(V) were efficiently eluted by H(2)O(2). In contrast, other metal ions were rarely recovered. The oxidation states of V(V), Mo(VI), and W(VI) were not changed ...
مطالعه حاضر به بررسی رمان خانه گرد اثر لوئیز اردریک در پرتو «مفهوم تأثیر» میپردازد. پاتریک کوم هوگان با ارائه نظریه تاثیر» روایت تجربه عاطفه و احساس سوژه ها را مورد هدف قرار می دهد. پژوهشگران این مقاله میکوشند تا مفاهیم عاطفه،روایت عاطفه، شرایط برانگیختن،همانندسازی،تعدیل ومنطقیسازی ردیابیکنند.سعی بر آن است فرایند پرداختهشود که چگونه روایت،احساسات عواطف همانندسازی میشوند پی تعدیل منطقی...
Candida albicans is one of the most common opportunistic fungi which cause oral cavity infections in humans. Most anti-fungal drugs posse side effects and may have an undesirable taste. Ginger is one of the oldest herbal products used in traditional medicine which has known antimicrobial effects and is used in the manufacture of Vi-One mouthwash. The present study was designed to investigate th...
This paper reports the evaluation of adsorbing Cr (VI) ions on sorbent prepared from chitosan (CHT), a versatile derivative of chitin, and dodecyl amine modified locally available kaolinite clay (Bijoypur clay) (MC) that has excellent mechanical properties and great resistance to chemical and biological attack. The effect of the initial metal ion concentration, solution pH, contact time, and ad...
مقدمه: تهدید عوامل شیمیایی و میکروبی هم در بعد نظامی و هم غیرنظامی اجتنابناپذیر است. روشهای حفاظت تنفسی وقتی افراد نظامی و غیرنظامی در معرض چنین عواملی قرار میگیرند خیلی مهم است. روش کار: در این تحقیق واکنشهای سمزدایی عوامل شیمیایی سمی بر روی دو نوع کربن فعال نظامی بنام ASC-pyridin حاوی Cu (II), Cr(VI), Ag (I) و pyridine و ASZMT-TEDA شامل Cu (II), Ag (I), Zn (II), Mo (VI) و TEDA مطالعه شده...
