We confirmed multiple picoeukaryotic algae, Ostreococcus, Micromonas, and Pelagomonas spp., as thiamine (vitamin B1) auxotrophs in laboratory experiments with axenic cultures. Examined strains have half saturation growth constants (Ks) for B1 between 1.26 and 6.22 pmol B1 L , which is higher than reported seawater concentrations. Minimum B1 cell quotas for Ostreococcus and Micromonas spp. are h...

Background: This cross sectional study was conducted to evaluate the effect of &gamma-rays and electron-beam irradiation with a commercial toxin binder-milbond-TX on the performance, feed components, and meat quality of Japanese quails challenged with aflatoxin B1. Methods: Overall, 168 One-d-old chicks (Japanese quails) were allocated to eight treatments with three replicates based on a com...

Introduction: At very high magnetic field, strong B1 heterogeneities occur in human MR images as RF wavelength becomes equal to, or smaller than, the size of the imaged target, interacting with lossy and dielectric properties of biological tissues(1,2). Different RF Shim techniques can be used in order to mitigate B1 inhomogeneities, which have considerable differences in their respective hardw...

Bois noir, an economically important disease of grapevine yellows that causes significant economic losses in wine production, is associated with ‘Candidatus Phytoplasma solani’ and transmitted to grapevines by cixiids Hyalesthes obsoletus Reptalus panzeri. Polyphagous planthopper Dictyophara europaea, commonly found natural habitats, harbors phytoplasmas from distinct groups alternative vector ...

background : the prevalence of anemia in hiv infected patients has not been well characterized in iran. this study aimed to describe the prevalence of anemia and related factors in hiv positive patients. methods : in a cross-sectional study, anemia prevalence and risk factors of 212 hiv positive patients were assessed, at the behavioral disease consulting center in isfahan. the relationship bet...

TGF-b1 and VEGF, both angiogenesis inducers, have opposing effects on vascular endothelial cells. TGF-b1 induces apoptosis; VEGF induces survival. We have previously shown that TGF-b1 induces endothelial cell expression of VEGF, which mediates TGF-b1 induction of apoptosis through activation of p38mitogen-activated protein kinase (MAPK). Because VEGF activates p38 but protects the cells from ap...
