Chlorinated organic compounds are ubiquitously detected in saline waters. The photochlorination of is one possible source, and chlorine radicals originating from other photosensitive substances have been reported to be responsible for chlorination previous reports. In this study, benzo[a]pyrene (BaP) 10% acetonitrile/NaCl aqueous solution was initiated by self-sensitization BaP, while were not ...

Benzo(a)pyrene (BaP) is highly carcinogenic in rats but is without effect in rabbits when administered s.c. The possibility that BaP-DNA adducts could be responsible for this species difference was investigated by comparing BaP-deoxyribonucleoside adducts formed in dermal fibroblast cultures from Wistar rats and New Zealand rabbits. Treatment with [G-3H]BaP (1.2 microM) for 6, 24, and 48 h prod...

We developed a gas chromatography-isotope dilution high-resolution mass spectrometry (GC-ID-HRMS) method for quantifying isomers of benzo[a]pyrene (BaP) tetrol metabolites resulting from hydrolysis of benzo[a]pyrene-diol-epoxide hemoglobin (BaPDE-Hb) adducts. Acid hydrolysis of BPDE-Hb adducts extracted from human blood samples yielded isomers of benzo[a]pyrene-tetrahydrotetrols, (+/-)-BaP-r-7,...

This experiment was conducted to investigate the effects of Bacillus amyloliquefaciens probiotic (BAP) as a direct-fed microbial on growth performance, cecal microflora, serum immunoglobulin levels, and fecal noxious gas emissions of broiler chickens. A total of 400 one-day-old broiler chicks (Ross 308) were randomly assigned to 1 of 5 treatment diets formulated to supply 0, 1, 5, 10, and 20 g/...

Repeated cycles of vascular injury by benzo(a)pyrene (BaP) increase the onset and progression of atherosclerotic lesions in laboratory animals. This atherogenic response is partly mediated by activation of cis-acting antioxidant/electrophile response elements that enhance c-Ha-ras transcription in vascular smooth muscle cells (vSMCs). Activation of antioxidant/electrophile responsive cis-acting...

Availability of quality seeds in production krisan (Chrysanthemum morifolium Ramat cv Dewi ratih) cultivation is still rare, therefore research on seed multiplication through tissue culture needed. The media used relatively expensive for home industry. This study aims to determine the respond leaf and stem explants using foliar fertilizers (Growmore, Gandasil D Mutiara) as an alternative callus...
