Soybean, Glycine max (L.) Merr. cv Essex, plants were grown in the field in a 2 x 2 factorial design, under ambient and supplemental levels of ultraviolet-B (UV-B) radiation (supplemental daily dose of 5.1 effective kilojoules per square meter) and were either well-watered or subjected to drought. Soil water potentials were reduced to -2.0 megapascals by the exclusion of natural precipitation i...

Enhanced UV radiation levels and decreased rainfall in Mediterranean terrestrial ecosystems due to climate change might impact soil bacterial communities, significantly altering their structure affecting biogeochemical cycles. The aim of this study was evaluate the effect UV-B UV-A on richness, abundance community composition a Lithic Dystroxerept shrubland determine whether these effects depen...

the role of the antioxidant defense system was studied in brassica napus, and subjected todifferent supplementary bands of ultraviolet radiation (uv-a, uv-b and uv-c). this study showed thatuv-b and uv-c induced oxidative stress as evidenced by an increase in lipid peroxidation and totalascorbate content. under uv-b and uv-c treatments, flavonoids and anthocyanins were increasedsignificantly co...

Superinfection exclusion is the phenomenon whereby a virus prevents the subsequent infection of an already infected host cell. The Pekin duck hepatitis B virus (DHBV) model was used to investigate superinfection exclusion in hepadnavirus infections. Superinfection exclusion was shown to occur both in vivo and in vitro with a genetically marked DHBV, DHBV-ClaI, which was unable to establish an i...

background the treatment of onychomycosis is a challenge and infections are typically more severe and difficult to treat in toenails than in fingernails. objectives the current study aimed to investigate the fungicidal effect of ultraviolet radiation on the growth of dermatophytes isolated from nails. patients and methods samples from patients with clinical manifestations of onychomycosis were ...

In the current study, we used four soybean varieties PK-1029, PK-472, NRC-7, and Hardee to examine effect of exclusion solar UV radiation on photosynthetic efficiency test possible variety-dependent sensitivity ambient (280-400 nm). Plants that were grown under filters had higher chlorophyll a b, efficiencies PSII more active reaction centers indicated substantially affected by radiation. The s...
