Ultraviolet B efficacy in improving antileishmanial effects of silver nanoparticles
Objective(s):Cutaneous Leishmaniasis (CL) is a parasitic disease caused by various species of the flagellated protozoan, Leishmania. Regardless of the numerous studies, there are still serious challenges in the treatment of CL. This study aimed at evaluating the influence of a low dose ultraviolet B (UVB) radiation along with silver nanoparticles (AgNPs) on a mouse model of CL induced by Leishm...
متن کاملUltraviolet B but not ultraviolet A radiation initiates melanoma.
Cutaneous malignant melanoma is one of the fastest increasing cancers with an incidence that has more than doubled in the last 25 years. Sunlight exposure is strongly implicated in the etiology of cutaneous malignant melanoma and the UV portion of the sunlight spectrum is considered responsible. Data are, however, conflicting on the roles of ultraviolet B [UVB; 280-320 nanometers (nm)] and ultr...
متن کاملMorphological and Biochemical Responses of Basil Plant Under Ultraviolet Radiation-B and Deficit Irrigation Under Greenhouse Conditions
Environmental stresses such as deficit irrigation and ultraviolet radiation can influence plant growth and development. Among the environmental variables, ultraviolet radiation is an important factor in plant response to other stresses, such as deficit irrigation. The purpose of this study was to investigate the effects of ultraviolet B radiation (UV-B), irrigation stress and combined effects o...
متن کاملAmphibian defenses against ultraviolet-B radiation.
As part of an overall decline in biodiversity, amphibian populations throughout the world are disappearing. There are a number of potential causes for these declines, including those related to environmental changes such as increasing ultraviolet-B (UV-B) radiation due to stratospheric ozone depletion. UV-B radiation can kill amphibian embryos or can cause sublethal effects that can harm amphib...
متن کاملSome Ultraviolet Photomicrographs of B. Subtilis
1. Type-specific antipneumococcus immunity has been induced in rabbits by immunization with antigen prepared by combining a specific derivative of the capsular polysaccharide of Type III Pneumococcus with globulin from horse serum. 2. Rabbits immunized with this antigen acquire active immunity against infection with virulent Type III pneumococci. 3. The sera of the immune rabbits contain type-s...
