background and aims: despite the screening of blood donors, blood transfusion represents an ideal port of entry for blood-borne infection. blood-borne pathogen transmission has been a concern since the earliest days of transfusion. the blood product of platelet (plt) concentrates is still faced with the risk of bacterial and viral contaminations. pathogen inactivation technologies offer a proac...

the effects of uv-c illumination at the dosage of 6.6 kj m-2 on postharvest quality of mango fruit cv. ‘kaew kamin’ during storage at 25 or 12°c were investigated. the changes in fresh weight, texture, ripening index (ri), peel and pulp colours, visual appearance, total carotenoids (tc) and ascorbic acid (asa) content were determined on days 0, 4, 8, 12 and 16 of storage. uv-c irradiation effec...

in this study, both the presence and concentration of some unsaturated compounds in hexane extracts of different parts of anthemis talyschensis showing absorption at wavelength 280-450 nm were surveyed, with the view of possibly using extracts of this plant in new formulations of sunscreen creams. the hexane extracts of flower, leaf and stem of a. talyschensis , collected from northwest iran, w...

in order to identify the effects of vitamin a and aspirin on reducing uv lightinduced retinopathy, erg waves were compared before and after uv light exposure in rabbits. 30 rabbits were divided into 3 groups: the first group received vitamin a, 50,000 units i.m., single dose, the second group received aspirin, 50 mg/ kg/day po and the third group did not receive any medication. all three groups...

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 ...

UV-B radiation and EOD light (EOD) quality has both signaling and damaging effects based on the dosage and time of exposure. At highland areas UV-B decreases crop productivity and also light quality increase at high elevation area but EOD light quality effect was not researched based on altitude. Therefore, in the present study a field experiment was conducted to investigate the effects of UV-B...

In order to identify the effects of vitamin A and aspirin on reducing UV lightinduced retinopathy, ERG waves were compared before and after UV light exposure in rabbits. 30 rabbits were divided into 3 groups: the first group received vitamin A, 50,000 units I.M., single dose, the second group received aspirin, 50 mg/ kg/day PO and the third group did not receive any medication.
