The relationship between cell killing and the binding of the anticancer drug cis-diamminedichloroplatinum(II) (cis-DDP) to DNA was studied in six mammalian cell lines. Two of the human cell lines (COV413B) were of the same origin, comprising one sensitive to cis-DDP and the other with induced resistance to the drug. The four other lines, two rodent (RIF-1, Chinese hamster ovary) and two human (...
BACKGROUND Proton transfer reaction-mass spectrometry (PTR-MS), in its recently developed implementation based on time-of-flight mass spectrometry (PTR-TOFMS), was used to rapidly determine the volatile compounds present in fruits of Capsicum spp. RESULTS We analyzed the volatile organic compounds emission profile of freshly cut chili peppers belonging to three species and 33 different cultiv...
به منظور مطالعه زنگ های تیره salicaceae در ناحیه البرز مرکزی، نمونههای متعددی از گونههای جنس salix و populus که به زنگ آلوده بودند از مکانهای مختلف این ناحیه جمع آوری و بررسی شدند. شناسایی گیاهان جمع آوری شده نشان داد که گونه های populus nigra، p. euphratica، salix alba و s. excelsa میزبانهای غالب از تیره salicaceae برای گونههای زنگ در ناحیه مورد مطالعه محسوب میشوند. نمونههای بررسی شده...
Tan spot, caused by Pyrenophora tritici-repentis, and fusarium head blight (FHB), the Fusarium graminearum species complex, are among main wheat diseases worldwide. This 3-year field study evaluated effect of soil incorporation calcium silicate, a source silicon (Si), to manage tan spot FHB improve grain yield quality. The Si was compared on two cultivars contrasting in disease resistance assoc...
The effects of osmotic and matric water potential on mycelial growth, production and germination of conidia, and production and maturation of pseudothecia of Pyrenophora triticirepentis (PTR), the cause of tan spot of wheat, were examined on clarified V8 juice agar amended with KCl or polyethylene glycol 8000 (PEG8000). Patterns of the growth responses of three isolates to decreasing osmotic an...
