The Suretka glass frog, Hyalinobatrachium chirripoi, has been recently rediscovered in the southeastern region of Costa Rica. This species was last reported in Costa Rica in the 1950's. H. chirripoi is distinguished from H. colymbiphyllum, which appears to be its most closely Costa Rican related taxon, by having extensive webbing between fingers II-III.
ABSTRACT: Of the antisperm immunoglobulins ,only antisperm surface IgA an IgGs are significant clinically because many fertile men have antisperm antibodies present in their sera. Since the necessity of one form of sperm surface antisperm test(specific)is felt in our country,and Immunobead is not popular here for its high cost,Mixed Antiglobulin Reaction test was studied in a population of inf...
امروزه روش های آماری و فرمول های استاندارد برای تحلیل داده های کامل توسعه یافته است، اما وجود داده ی گمشده در مجموعه ی داده ها می تواند منجر به برآوردهای اریب شود و روش های استاندارد تحلیل داده های آماری نمی توانندمورد استفاده قرار گیرند لذا باید با استفاده از روش های مختلف داده جانهی، نقص در مجموعه ی داده ها را برطرف کنیم. تنوع روش های مختلف داده جانهی ایجاب می کند که محقق براساس ملاک های موجو...

Low-level and unstable transgene expression are common issues using the CHO cell expression system. Matrix attachment regions (MARs) enhance transgene expression levels, but additional research is needed to improve their function and to determine their mechanism of action. MAR-6 from CHO chromosomes actively mediates high and consistent gene expression. In this study, we compared the effects of...
In this paper, we demonstrate a novel carbon nanotube (CNT) reinforced macroporous adsorption resin (MAR) for the first time. The CNTs were dispersed in water via sonication, and then in situ physically entrapped in the pores of MAR by capillary forces and sonication. The resulting CNT reinforced MAR (CNT-MAR) was proved by transmission electron microscopy (TEM) and confocal laser scanning micr...
In this study, gamma rays were used to irradiate embryogenic calli induced from cotyledon explants of Panax ginseng Meyer. After the embryogenic calli were irradiated, they were transferred to adventitious roots using an induction medium; next, mutated adventitious root (MAR) lines with a high frequency of adventitious root formations were selected. Two MAR lines (MAR 5-2 and MAR 5-9) from the ...
متداولترین روشهای مورد استفاده برای تعیین آنتیبادیهای ضد اسپرم آزمون اتصال ایمونویید و واکنش آگلوتیناسیون مختلط میباشند. تعیین ASA با روش فلوسیتومتری اولینبار بهوسیلهHaas و Cunningham شرح داده شد. هر دو روش میتوانند بهطور مستقیم یا غیرمستقیم انجام شوند. در این مطالعه FCM غیرمستقیم با MAR مستقیم جهت تعیین آنتیبادیهای ضداسپرم مقایسه گردیده است روش بررسی مایع منی مردان 80 زوج نابارور مر...
Background: Malnutrition in children including lower nutrient intakes or high density food intakes is of recent world concerns; therefore, determining a simple index that reveals the diet adequacy might be an advantage. Methods: This cross-sectional study was done among 233 children aged 2-5 years old. A 24-hour dietary questionnaire was used to calculate mean adequacy ratio (MAR), naturally nu...
Introduction: The precise mechanism for antisperm antibody (ASA) mediated fertility impairment is unclear. In the male reproductive tract, ASA may have an adverse impact on sperm maturation and function or overall semen quality. In this study, the percentage of ASA-IgA was determined by the direct Mixed Agglutination Reaction (MAR) test in men from infertile couples in Khorramabad city. Further...
