PURPOSE To estimate the direct effects of self-reported visual impairment (VI) on health, disability, and mortality and to estimate the indirect effects of VI on mortality through health and disability mediators. METHODS The National Health Interview Survey (NHIS) is a population-based annual survey designed to be representative of the U.S. civilian noninstitutionalized population. The Nation...
OBJECTIVE Periodontal disease is a set of inflammatory infections that affect the supporting structures of the dentition. Patients with visual impairment (VI) may have more difficulty in cleaning and maintaining oral health. The purpose of this study was to investigate the possible relationship between periodontal status and degree of VI in institutionalized individuals. MATERIALS AND METHODS...
A simple batch method for the fluorometric determination of hydrogen peroxide using phosphine-based fluorescent reagents has been developed. A rapid, mild and selective derivatization reaction was achieved by adding sodium tungstate dihydrate to the reaction mixture of hydrogen peroxide and a phosphine-based fluorescent reagent. When 4-diphenylphosphino-7-methylthio-2,1,3-benzoxadiazole was use...
Myosin VI moves towards the minus end of actin filaments unlike all the other myosins so far studied, suggesting that it has unique properties and functions. Myosin VI is present in clathrin-coated pits and vesicles, in membrane ruffles and in the Golgi complex, indicating that it has a wide variety of functions in the cell. To investigate the cellular roles of myosin VI, we have identified a v...
Although myosin VI has properties that would allow it to function optimally as a dimer, full-length myosin VI exists as a monomer in isolation. Based on the ability of myosin VI monomers to dimerize when held in close proximity, we postulated that cargo binding normally regulates dimerization of myosin VI. We tested this hypothesis by expressing a known dimeric cargo adaptor protein of myosin V...
Myosins play countless critical roles in the cell, each requiring it to be activated at a specific location and time. To control myosin VI with this specificity, we created an optogenetic tool for activating myosin VI by fusing the light-sensitive Avena sativa phototropin1 LOV2 domain to a peptide from Dab2 (LOVDab), a myosin VI cargo protein. Our approach harnesses the native targeting and act...
PURPOSE The aim of this study is to investigate the 4-year incidence and progression of visual impairment (VI) and the associated risk factors for incident VI in a South Indian population with type 2 diabetes. METHODS A total of 634 participants with type 2 diabetes were found eligible after 4 years. Visual acuity (VA) was estimated using the modified Early Treatment Diabetic Retinopathy Stud...
یک کمپلکس باز شیف اورانیل جدید با فرمول [uo2(l)(dmf)] که در آن ( (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenol ) l= 2, 2'-((1e, 1e')-(1, 2 phenylen bis می باشد از واکنش لیگاند h2l و نمک (ch3coo)2uo2·2h2o تهیه شد. ساختار شیمیایی کمپلکس به دست آمده توسط دستگاه های طیف سنجی مادون قرمز فوریر ، پروتون انمار ، طیف سنجی فرا بنفش-مریی ، لومینسانس و طیف سنجی بکمک اشعه ای...
The adsorption of Cr(VI) on the raw multiwalled carbon nanotubes (MWCNTs) as a function of initial Cr(VI) concentration, pH, temperature, and MWCNT dosage were studied. The removal of Cr(VI) from aqueous solution was dominated by adsorption of Cr(VI) and redox reaction of Cr(VI) to Cr(III). The adsorption of Cr(VI) decreased with increasing pH and increased with the rise in temperature and MWCN...
در این پروژه، یک لیگاند شیف باز جدید دو دندانه بوسیله تراکم یک آلدهید آلی سیلیکونی جدید با اتانول آمین سنتز گردید. این نانو کمپلکس ناجور دو فلزی [mo(vi),vo(v)] تحت شرایط فراصوت تهیه گردید. شناسایی ساختار و ریخت شناسی نانو کمپلکس ناجور دو فلزی بوسیله تکنیک¬های مختلفی مثل xrd، ft-ir، طیف سنج رامان، tga، icp، tem انجام گرفت. این نانو کمپلکس ناجور دو فلزی در کاتالیز کردن ناهمگن اکسایش هوازی آلکیل ...
