Objectives: To evaluate the effect of intense pulsed light (IPL) on Trichophyton rubrum and investigate its mechanism of action. Methods: The viability of fungi treated with IPL alone and with IPL combined with an NADPH oxidase inhibitor (DPI) pretreatment was determined by MTT assays. The reactive oxygen species (ROS) were quantified with a DCFH-DA fluorescent probe. Malondialdehyde (MDA) cont...

micromorphology is the branch of soil science that is concerned with the description, interpretation and, to an increasing extent, the measurement of components, features and fabrics in soils at microscopic level. the advantage of micromorphology is that, in micromorphological studies the soils are studied in their natural and undisturbed form and so, one can follow the processes that take plac...

soils of the arid–semiarid karaj basin in north-central iran have formed on alluvium-colluvium derived from mixed calcareous-gypsiferous marls of miocene and basic igneous rocks of holocene age. in order to characterize and classify the soils and to determine the soil-landscape relationship in the area, sixteen pedons located on different physiographic positions have been described, sampled and...

macro and micromorphological investigations were conducted on selected xerepts soils from southern iran to identify changes in soil characteristics with time. soil samples from similar pedons of four irrigated orchards ranging in age from 20 to 100 years were studied and compared with soil samples of a pedon of non-irrigated land. in addition to routine analyses, undisturbed blocks of soils...

abstract geomorphology and soil genesis and its development are closely related. besides, soil-landscape studies provide a better understanding of soil forming processes. the objectives of the present research include soil genesis studies, micromorphology and clay mineralogy of soils related to geomorphic surfaces in jiroft area. soil temperature and moisture regimes of the area are hyperthermi...

Cryptantha (Boraginaceae) is a group of approximately 200 annual and perennial species, representing two-thirds of the diversity within subtribe Cryptanthinae. The genus exhibits an amphitropic distribution, occurring in temperate and desert regions of western North and South America. Fifty samples of 45 species of Cryptantha s. l., exemplars of the related genera Amsinckia, Pectocarya, and Pla...
