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 ...

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...

The recently solved structure of the myosin VI motor demonstrates that the unique insert at the end of the motor is responsible for the reversal of the normal myosin directionality. A second class-specific insert near the nucleotide-binding pocket contributes to myosin VI's unique kinetic tuning, allowing it to function either as an actin-based transporter or as an anchoring protein. Recent bio...

The title compound, bis-[4,4'-(propane-1,3-di-yl)-dipiperidin-ium] β-octa-molybdate(VI), (C(13)H(28)N(2))(2)[Mo(8)O(26)], was produced by hydro-thermal reaction of an acidified aqueous solution of Na(2)MoO(4)·2H(2)O and 4,4'-trimethyl-ene-dipiperidine (L). The structure of the title compound consists of β-octa-molybdate(VI) anion clusters and protonated [H(2)L](2+) cations. The octa-molybdate a...

Co-doped ZnO nanoparticles with different Cobalt contents were prepared by direct precipitation method. The materials were characterized by XRD, SEM and TEM techniques. The XRD results indicated that the particle size of pure ZnO and Co-doped ZnO is about 30-45nm. The toxic Cr(VI) in industrial wastewaters can be removed by a reduction from Cr(VI) to Cr(III). The reduction of Cr(VI) to Cr(III) ...

Introduction: Chromium (VI) is a known human carcinogenic agent which is used in numerous industrial processes such as electroplating, welding, textile, cement and steel fabrication. The aim of this study was to determine the effectiveness of natural zeolite on the fixed bed adsorption of Cr (VI) from air stream. . Material and Method: In this experimental study, chromium mists were generated...

N-Hydroxy-desferrioxamine B (5), a postulated metabolite of the microbial product desferrioxamine B (1), has been prepared by reduction of the intermediate oxime 6 with sodium cyanoborohydride. The oxime was obtained by selective oxidation of desferrioxamine B with hydrogen peroxide and a catalytic amount of sodium tungstate dihydrate. The iron complex derived from 5 enabled definite proof of t...
