Susceptibility to photoimmune suppression and photocarcinogenesis is greater in male than female humans mice exacerbated estrogen receptor-beta knockout (ER-β−/−) mice. We previously reported that the active vitamin D hormone, 1,25-dihydroxyvitamin D3 (1,25(OH)2D), applied topically protects against ultraviolet radiation (UV) induction of cutaneous cyclobutane pyrimidine dimers (CPDs) contact h...

this study aimed to determine phenolic compounds of artemisia spicigera (family asteraceae) growing in east-azarbaijan province of iran. 20%, 40 % and 60% spe fractions of methanolic extract of a. spicigera, were subjected to reversed phase preparative hplc, with the mobile phase consisted of methanol and water. structural identification of phytochemicals by spectroscopic methods including uv a...

background  and  objectives: pseudomonas  aeruginosa is responsible for devastating nosocomial infections among severely burn patients. class c of cephalosporinase (ampc-β-lactamases) is important cause of multiple β-lactam resistance in p. aeruginosa . the aim of this study was to detect the ampc-β-lactamases producing isolates among carbapenem resistant p.  aeruginosa isolated from burn patie...

background: tay-sachs disease (tsd), or gm2 gangliosidosis, is a lethal autosomal recessive neurodegenerative disorder, which is caused by a deficiency of beta-hexosaminidase a (hexa), resulting in lysosomal accumulation of gm2 ganglioside. the aim of this study was to identify the tsd-causing mutations in an iranian population. methods: in this study, we examined 31 patients for tsd-causing mu...

conclusions this study was the first report of the emergence of the plasmid-encoded blaoxa genes among e. cloacae isolates in iran. these findings highlight the need to use appropriate infection control policy and rational antibiotic therapy to reduce further spread of these resistant bacteria in the studied hospitals. results in total, 48 esbl-producing isolates (58.5%) were positive for the b...

phenylazo and benzothiazolylazo derivatives of trifluoroacetylacetone andhexafluoroacetylacetone have been synthesized and characterized. analytical and spectral datarevealed the existence of phenylazo derivatives in the intramolecularly hydrogen-bonded ketohydrazoneform while the benzothiazolylazo derivatives in the azo-enol form. the monobasicbidentate coordination of the phenylazo derivative...

This study is part of the Follow up Restoration Program of animal communities that colonize the Guadiamar River Basin. In 1998, the area was affected by a release of toxic sludge after the retention walls of the Aznalcóllar Mines (southern Iberian Peninsula) broke. The main objective of this study was to assess the current state of the population of Tenebrionidae, one of the most representative...

Fish is one of the eight major foods causing type-I food allergy, and prevalence its allergy increasing in part due to changes consumption habits. One main drivers for these has been processing developments transforming fish muscle into seafood products. Most allergic patients react Ca2+-binding protein β-parvalbumin (β-PV) abundant muscle. Here we have analyzed effect content allergenic proper...
