Invitro antioxidant activity and Molecular modeling studies of nine chromone derivatives optimize their inhibitory activity against Poly [ADP correlated to different molecular properties. The AM1and PM3 semiempirical methods are used to estimate vertical ioniz tion potentials (IPv’s), electron affinity (EA tion coefficient (LogP), hydration energ regression analysis are proposed. The leave fina...

Background Human immunodeficiency virus (HIV) infection causes acquired immune deficiency syndrome (AIDS) and is a global public health issue. Anti-HIV therapy involving chemical drugs has improved the life quality of HIV/ AIDS patients. However, emergence of HIV drug resistance, side effects and the necessity for long-term antiHIV treatment are the main reasons for failure of antiHIV therapy. ...

Fertilization of the sea urchin egg is accompanied by the assembly of an extracellular glycoprotein coat, the fertilization membrane. Assembly of the fertilization membrane involves exocytosis of egg cortical granules, divalent cation-mediated association of exudate proteins with the egg glycocalyx (the vitelline layer), and cross-linking of the assembled structure by ovoperoxidase, a fertiliza...

In many species, females are thought to benefit from polyandry due to the reduced risks of fertilization by genetically incompatible sperm. However, few studies that have reported such benefits have directly attributed variation in female reproductive success to the interacting effects of males and females at fertilization. In this paper, we determine whether male x female interactions influenc...

When using phiX174 RFI DNA as a template, invitro, E. coli RNA polymerase synthesizes four major purine triphosphate-containing 5' end sequences. RNase A digests of alpha(32)P labeled RNA were further digested with spleen exonuclease to remove the bulk of the oligonucleotides with 5' hydroxyls and then chromatographed on DEAE cellulose to resolve the remaining 5' terminal oligonucleotides. By a...

An elegant synthesis of newer aminobenzylated mannich bases (6a to 6j) is described in the present study. These were synthesized by reacting aromatic aldehydes, cyclic secondary amines and a reagent with active hydrogen atom such as Urea in the presence of hydrochloric acid. The constituents of the newly synthesized compounds have been established on the basis of their physical and spectral dat...

We demonstrate the deliberate activation or inhibition of invitro angiogenesis using functional peptide coated gold nanoparticles. The peptides, anchored to oligo-ethylene glycol capped gold nanospheres, were designed to selectively interact with cell receptors responsible for activation or inhibition of angiogenesis. The functional particles are shown to influence significantly the extent and ...

BACKGROUND In its 1993 report the Canadian Royal Commission on New Reproductive Technologies challenged the effectiveness of in vitro fertilization for severe male infertility. To address the Commission's concern, the authors compared the relative effectiveness of in vitro fertilization combined with intracytoplasmic sperm injection for severe male infertility and conventional in vitro fertiliz...
