In considering factors that might influence measurement of free thyroxin (T4), we evaluated the proportion (%) of T4 that could be stripped from thyroxin-binding globulin (TBG). The percentage of free T4 was measured in serially diluted sera from four normal subjects, four patients with hyperthyroidism or hypothyroidism, four pregnant women, and four malnourished subjects with low TBG. The crit...

Background: Iron deficiency impairs the proliferation and function of T lymphocytes. This study was conducted to assess the relationship between serum iron with percentage of TCD4 and TCD8 lymphocytes in peripheral blood of female high school students in Hamadan.  Methods: In this cross-sectional study, 355 female high school students with an age range of 15-18 years were enrolled from Ja...

this study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. the resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. but by increasingof fire retar...

BACKGROUND Anemia commonly develops in patients with chronic kidney disease and is strongly associated with adverse clinical outcomes. There are currently no published studies evaluating the efficacy of a nurse-driven anemia-management protocol for patients with chronic kidney disease who are not receiving dialysis. OBJECTIVES To evaluate the efficacy of an anemia-management protocol in terms...

The increasing prevalence of multiple comorbidities among anemic patients with chronic kidney disease has made the use of serum ferritin and transferrin saturation more challenging in diagnosing iron deficiency. Because serum ferritin is an acute-phase reactant and because the inflammatory state may inhibit the mobilization of iron from reticuloendothelial stores, the scenario of patients with ...

BACKGROUND The purpose of this study was to investigate the repeatability of retinal oximetry using slit-lamp adapted ultrahigh-resolution optical coherence tomography (SL-UHR-OCT). METHODS SL-UHR-OCT was developed and fringe patterns were obtained for a major retinal artery and a major retinal vein. A-scans at the central wavelengths of 805 nm and 855 nm were analyzed for calculating optical...

BACKGROUND Two proteins carry vitamin B12 in plasma. Transcobalamin (TC) carries approximately 25% of total plasma vitamin B12 and is 6% to 20% saturated with cobalamin. Haptocorrin (HC) binds approximately 80% of total cobalamin and is largely saturated with cobalamin. METHODS We investigated the distribution and the relationship between concentrations of cobalamin, total and holo forms of T...

Peak emissions of NO and N(inf2)O are often observed after wetting of soil. The reactions to sudden changes in the aeration of cultures of nitrifying and denitrifying bacteria with respect to NO and N(inf2)O emissions were compared to obtain more information about the microbiological aspects of peak emissions. In continuous culture, the nitrifier Nitrosomonas europaea and the denitrifiers Alcal...

A 39-year-old man presented to the emergency department after falling downstairs after he consumed a large quantity of alcohol. On examination, he had altered mental state (GCS 14), central cyanosis and low oxygen saturation of 86%, despite 100% oxygen being administered. His arterial blood gas confirmed diagnosis of methaemoglobinaemia with a methaemoglobin percentage of 14.08. He was treated ...

1. Haematological and respiratory parameters (including RBC count, CO2 content and percentage oxygen saturation) were studied in coldacclimated (12 ± 1 °C) and normal frogs (23 + 2 °C). 2. Seasonal variation in RBC count was found, the count being higher in January than in September. Females showed higher counts than males. Coldacclimation resulted in the elevation of counts in all seasons and ...
