Although immunoassays in measuring 25-hydroxyvitamin D [25(OH)D] have been improved recently, relatively large differences are still seen between results of 25(OH)D measured by immunoassays and by liquid chromatography-tandem mass spectrometry (LC-MS/MS). In the present studies, we compared two immunoassays with LC-MS/MS for measuring 25(OH)D concentrations. Concentrations of 25-hydroxyvitamin ...
PURPOSE Vitamin D deficiency is a global health problem that is associated with increased risks of major diseases. This study investigated the status of 25-hydroxyvitamin D [25(OH)D] and its demographic and lifestyle determinants among Korean adults. METHODS A total of 5,847 adults who had participated in the Korean National Health and Nutrition Examination Survey of 2008 (KNHANES) were inclu...
BACKGROUND Epidemiological studies suggest a link between vitamin D deficiency in early life and development of asthma in later life. AIM The aim of this study was to measure serum vitamin D levels in asthmatic children and to compare these to healthy non-asthmatic controls. METHODS Asthmatic (n = 483) and healthy control (n = 483) children were recruited from the Pediatric Allergy-Immunolo...
Three new cycloartane-type triterpene glycosides have been isolated from the aerial parts of Astragalus trojanus. The structures were established mainly by a combination of one- and two-dimensional NMR techniques [1H-1H-correlation spectroscopy (COSY), 1H-13C-heteronuclear multiple quantum correlation spectroscopy (HMQC), and 1H-13C-heteronuclear multiple-bond correlation spectroscopy (HMBC)] a...
OBJECTIVE This study evaluated the change and function of the pancreas, and small intestine in relation to growth performance of broilers on diets supplemented with raw soybean meal (RSBM) and protease. Samples of test ingredients and diets, after mixing and prior to being used were also assessed on contents of anti-nutritional factors. METHODS A 3×3 factorial study was used, with three level...
برهمکنش پورفیرازین کاتیونی تتراکیس(n,n,n,n -4,3-تتراپیریدینو) روی(ii) (zn(tmtppa))با پلی نوکلئوتیدهای سنتزی: poly[d(g-c)]2 و poly[d(a-t)]2 و dna غده تیموس گوساله در بافر فسفات 5/7 میلی مولار با ph 2/7 با استفاده از تکنیک های اسپکتروسکوپی جذب نوری و فلورسانس مطالعه شده است. کاهش جذب بیشتر از % 40 در طیف uv-vis پورفیرازین به دلیل برهمکنش با هر دو پلی نوکلئوتیدهای poly[d(g-c)]2 و poly[d(a-t)]2 م...
Abstract Background and Objective: Of the most common hypochromic microcytic anemia are iron deficiency anemia and minor thalassemia, which are common in Iran and their differential diagnosis is extremely important. The level of 25-hydroxy vitamin D is the indication of vitamin D blood status. The aim of this study was to compare serum levels of vitamin D in people with minor thalassemi...
AbstractIn the present work we set out to investigate the neuroprotective effects of noscapine (0.5-2 µM) in presence of D-glucose on primary murine foetal cortical neurons after oxygen–glucose deprivation/24 hrs recovery. Cell viability, nitric oxide production and intracellular calcium ([ca2+]i) levels were evaluated by MTT assay, the modified Griess method and Fura-2 respectively. 25 and 100...
