BACKGROUND Interpretation of laboratory test results with appropriate diagnostic accuracy requires reference or cutoff values. This study is a comprehensive determination of reference values for hematology and clinical chemistry in apparently healthy voluntary non-remunerated blood donors and pregnant women. METHODS AND FINDINGS Consented clients were clinically screened and counseled before ...

Two hundred cases of renal transplantation from living donors are reported from Shahid Hashemi Nejad Medical Center in Iran. There were 127 male and 73 female patients with 67% in the third and fourth decade of life. All patients received grafts from living donors with 114 cases of HLA haploidentical, 55 cases of HLA identical matches and 24 unrelated donors. One year patient and graft survival...

A series of non-heme iron(ii) bis(triflate) complexes containing linear and tripodal tetradentate ligands has been prepared. Electron withdrawing and electron donating substituents in the para position of the pyridine ligands as well as the effect of pyrazine versus pyridine and sulfur or oxygen donors instead of nitrogen donors have been investigated. The electronic effects induced by these su...

Endosymbioses between animals and chemoautotrophic bacteria are ubiquitous at hydrothermal vents. These environments are distinguished by high physico-chemical variability, yet we know little about how these symbioses respond to environmental fluctuations. We therefore examined how the γ-proteobacterial symbionts of the vent snail Ifremeria nautilei respond to changes in sulfur geochemistry. Vi...

The search for novel anti-malarial drugs that can disrupt biomineralization of ferriprotoporphyrin IX to haemozoin requires an understanding of the fundamental chemistry of the porphyrin's iron(iii) centre at the water-lipid interface. Towards this end, the binding affinities for a diverse set of 31 small ligands with iron(iii) porphine have been calculated using density functional theory, in t...

Idiopathic male infertility may be due to exposure to environmental toxicants that alter spermatogenesis or sperm function. We studied the relationship between air pollutant levels and semen quality over a 2-year period in Los Angeles, California, by analyzing repeated semen samples collected by sperm donors. Semen analysis data derived from 5,134 semen samples from a sperm donor bank were corr...

Soil moisture status has an important effect on the process of denitrification in paddy soils. However, it is unclear how affects ferrous iron-involved denitrification. Here, influence drying-rewetting cycles soil were studied with batch experiments. The dynamics nitrate, ammonia, Fe2+, Fe3+ and total organic carbon (TOC), as well nitrous oxide (N2O) investigated using iron-rich Jiangxi provinc...
