Microbial infections, localized as well as systemic, are known to cause transitive or permanent male infertility. However, the mechanisms of infection-induced infertility are largely unknown. Earlier reports showed that steroidogenesis and spermatogenesis are affected during bacterial lipopolysaccharide (LPS)-induced acute inflammation. The present study(More)
C-Phycocyanin (C-PC), the major light harvesting biliprotein from Spirulina platensis is of greater importance because of its various biological and pharmacological properties. It is a water soluble, non-toxic fluorescent protein pigment with potent anti-oxidant, anti-inflammatory and anti-cancer properties. In the present study the effect of highly(More)
C-Phycocyanin (C-PC) is one of the major biliproteins of Spirulina platensis, a blue green algae, with antioxidant and radical scavenging properties. It is also known to exhibit anti-inflammatory and anti-cancer properties. However, the mechanism of action of C-PC is not clearly understood. Previously, we have shown that C-PC selectively inhibits(More)
Celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, is the only non-steroidal anti-inflammatory drug so far which has been approved by the FDA for adjuvant treatment of patients with familial adenomatous polyposis. The molecular mechanism responsible for the anti-cancer effects of celecoxib is not fully understood. There is little data on the(More)
Growth inhibitory effects of 15-lipoxygenase-1 [13-(S)-HPODE and 13-(S)-HODE] and 15-lipoxygenase-2 [15-(S)-HPETE and 15-(S)-HETE] (15-LOX-1 and LOX-2) metabolites and the underlying mechanisms were studied on chronic myeloid leukemia cell line (K-562). The hydroperoxy metabolites, 15-(S)-HPETE and 13-(S)-HPODE rapidly inhibited the growth of K-562 cells by(More)
A total of 100 maize and 50 poultry feed samples collected in 1998 at random from nine and eight districts of Haryana, respectively, were analysed for fumonisin B1. The samples were collected from poultry farms, feed manufacturers and markets. Ninety one (91%) maize samples and forty two (84%) poultry feed samples were found to contain fumonisin B1.(More)
A study was conducted on 60 broiler chicks of the effect of activated charcoal (200 ppm) on the toxicity of 0.5 ppm aflatoxin B1 (AFB1) in feed fed from day 1 to day 42. Activated charcoal was found to be moderately effective in reducing the harmful effects of AFB1 as assessed by growth response and various biochemical parameters. The feeding of activated(More)
Synthetic deoxy-oligo duplexes containing short gaps of 1 and 4 nucleotides were used as model substrates to assess the DNA gap repair ability of the neuronal extracts prepared from cerebral cortex of rats of different ages. Our results demonstrate that gap repair activity in neurons decreases markedly with age. The decreased activity could be restored by(More)
High-throughput screening (HTS) involves testing of compound libraries against validated drug targets using quantitative bioassays to identify 'hit' molecules that modulate the activity of target, which forms the starting point of a drug discovery effort. Eicosanoids formed via cyclooxygenase (COX) and lipoxygenase (LOX) pathways are major players in(More)
It is well established now that dietary calorie restriction (CR) leads to extension of life span in many species, although the exact mechanism of this effect is still eluding. In the present study, we examined the effect of 40 % CR imposed during a prolonged period of life span (from 6 to 30 months) of rats on the activity of DNA polymerase β (pol β) in(More)
