to study the effect of type and different nitrogen fertilizers on controlling egyptian broomrape, field and greenhouse studies based on randomized complete block with three replications, were conducted at ferdowsi university of mashhad. greenhouse study treatments were consisted of ammonium nitrate, ammonium sulfate and urea each of which applied at four rates (75, 150, 300 and 350 kg/ha). fiel...
Nitidine chloride (NC), a quaternary ammonium alkaloid, has numerous pharmacological effects, such as anticancer activity. However, it was found that NC also has hepatocellular toxicity. Because organic cation transporters 1 and 3 (OCT1 and OCT3) might mediate the influx of NC into hepatocytes, multidrug and toxin extrusion 1 (MATE1) probably mediates the efflux of NC from hepatocytes, while cy...
nitrate and ammonium forms of nitrogen are being applied to improve plant growth and uptake of other nutrients. given that the effect of application of different nitrate to ammonium ratios accompanied by other fertilizers (i.e. fe, mn and zn) has not been studied on wheat growth as well as uptake of fe, mn and zn, three glasshouse pot studies were conducted with factorial arrangement of treatme...
This paper describes an LC-MS/MS method to determine the concentration of spironolactone and its metabolites 7-alpha-methylthiospironolactone and canrenone in blood plasma samples. The resulting assay is simple (using protein precipitation for sample preparation) and sensitive (the lower limit of quantification is close to 0.5 ng/ml) while requiring only 50 μl of plasma, making it especially su...
Vacuolating cytotoxin A (VacA) is one of the important virulence factors produced by H. pylori. VacA induces apoptotic cell death, which is potentiated by ammonia. VacA also causes cell death by mitochondrial damage, via signaling pathways that are not fully defined. Our aim was to determine whether endoplasmic reticulum (ER) stress is associated with VacA-induced mitochondrial dysfunction and ...
