The pharmacokinetics of [(3)H]-9-hydroxybenzo[a]pyrene (9-OH-BaP), a highly lipophilic primary metabolite of benzo(a)pyrene, were examined after intrapericardial (iv) or oral doses of 50 or 200 microg/kg to intermolt American lobsters, Homarus americanus. Combining data for all lobsters, the average terminal elimination half-life of parent 9-OH-BaP was 97.3 h after iv and 56.5 h after oral admi...

Oxidative stress has been reported to occur during surgery. It is important to reduce intraoperative oxidative stress to improve the postoperative prognosis. However, there are no reports regarding oxidative stress related to surgery in horses. In the present study, we measured pre and postsurgical diacron-reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP); the oxid...

The absorption efficiency (AE) of benzo[a]pyrene (BaP), a representative polycyclic aromatic hydrocarbon compound, in the green mussel Perna viridis was measured under different biological and food conditions (body size, food quantity, and food species). Uptake of BaP from the aqueous phase by different species of phytoplankton and green mussels was also experimentally quantified. A bioenergeti...

This study aims to dissociate the respective roles of systemic nephrosis and of the intrarenal effects of proteinuria in the pathogenesis of focal segmental glomerulosclerosis (FGS) in adriamycin nephrosis. To this purpose, this study examined proteinuria and FGS in bilateral (BAP) and unilateral proteinuria (UAP) in two different rat strains. UAP was obtained by protecting one kidney from expo...

The cognitive impairment characterizing the phenotype of older adults has been related to the efficiency of the antioxidant system. This study aimed at investigating the effect of memory training (MT) on memory, global cognitive functioning, and the oxidant and antioxidant capacity of plasma. We recruited 52 healthy subjects aged over 60. Twenty-nine subjects were submitted to 6-months of MT (E...

Different explants of Crocus sativus L. such as corm, style, ovary, petal, anther and leaf were cultured on LS and MS media supplemented with NAA and BAP or 2,4-D plus BAP at different combinations. Shoot and corm induction occurred in addition to the formation of other organs. Efficient plantlet regeneration with strong roots occurred at 1 mg 1-I of both NAA and BAP. An increase in 2,4-D l...

Aftermath in several air pollution episodes with high concentrations of polycyclic aromatic hydrocarbons did not significantly affect health and performance of broilers despite its renowned sensitivity to polycyclic aromatic hydrocarbons. The aim of the study was to elucidate the previous lack of response in birds exposed to such severe episodes of air pollution. Benzo[a]pyrene (BaP) was used t...

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...

In vitro clonal propagation of Ashoka, Saraca asoca (Roxb.) De Wilde plant was achieved using shoot tip, nodal and internodal explants. The explants were cultured on MS medium supplemented with different concentrations (0.5-2.0mg/l) of Benzyl amino purine (BAP), Kinetin (Kn) and 2, 4-Dichlorophenoxy acetic acid (2,4-D). The synergetic effect of BAP (0.5mg/ l) induced a mean of 11.71±0.53 advent...
