PURPOSE The results of previous immunocytochemical and electrophysiological studies of retinas of rd (retinal degeneration) chicks suggest that the iodopsin cone visual pigment may be defective in this mutant. The goal of this study was to determine if the primary structure and synthesis of this protein is normal in this animal model of inherited retinal degeneration. METHODS Northern cDNA se...
در این پژوهش، اثر نورد سرد و عملیات حرارتی کوتاهمدت روی ریزساختار و سختی آلیاژ آلومینیم 356A بررسی شد. مشاهدات ریزساختاری توسط میکروسکوپ نوری، آنالیز کمّی با استفاده از نرمافزار کلمکس و آزمون سختیسنجی توسط سختیسنج برینل انجام شد. نتایج نشان داد که فرایند نورد باعث ریز شدن، افزایش کرویت و کاهش نسبت طول به عرض ذرات سیلیسیم و نیز حذف تخلخلهای موجود در نمونهی ریختگی شد. توزیع ذرات سیلیسیم در م...
For identification and differentiation of different types of dolomites of the Padeha Formation, three stratigraphic sections in the northern and southern Tabas Block, with the maximum amount of dolomite, were selected and sampled. Based on petrographic evidence and geochemical data, three types of dolomite were identified, including primary (PD), replacement (RD) and vein and pore filling (VD) ...
Chronic kidney disease (CKD) is staged on the basis of glomerular filtration rate; generally, the MDRD study estimate, eGFR, is used. Renal dysfunction (RD) in heart transplant (HT) patients is often evaluated solely in terms of serum creatinine (SCr). In a cross-sectional, 14-center study of 1062 stable adult HT patients aged 59.1±12.5 yr (82.3% men), RD was graded as absent-or-mild (AoM), mod...
This study investigated the association between reading disability (RD) and internalizing and externalizing psychopathology in a large community sample of twins with (N = 209) and without RD (N = 192). The primary goals were to clarify the relation between RD and comorbid psychopathology, to test for gender differences in the behavioral correlates of RD, and to test if common familial influence...
We introduce concepts of intermediate rank for countable groups that “interpolate” between consecutive values of the classical (integer-valued) rank. Various classes of groups are proved to have intermediate rank behaviors. We are especially interested in interpolation between rank 1 and rank 2. For instance, we construct groups “of rank 7 4 ”. Our setting is essentially that of non positively ...
