Some new coordination compounds of tin(IV) having general formula [SnBu2 (L)2 ] (where L = carbohydrazone ligand) have been synthesized by the reaction of dibutyltin oxide with carbohydrazone ligands with the ratio of 1:2 (metal- ligand) using dry benzene as a reaction medium. The newly synthesized complexes were characterized by elemental analysis, molecular weight determinations, conductivity...

Biological activity of bovine kappa-caseino glycomacropeptide (GMP) has received much attention in recent years. Research has focused on the ability of GMP to bind cholera and Escherichia coli enterotoxins, inhibit bacterial and viral adhesion, suppress gastric secretions, promote bifidobacterial growth and modulate immune system responses. Of these, protection against toxins, bacteria, and vir...

Cytotoxic, antioxidant, tyrosinase inhibitory, antimicrobial activities of the crude ethanol extract of dry powdered roots of Asparagus racemosus (Liliaceae) were investigated. The LC(50) to brine shrimp was 2189.49 microg/ml; the EC(50) for DPPH radical scavenging was 381.91 microg/ml; the IC(50) for tyrosinase inhibition was 7.98 mg/ml. The extract was active at 5-20 mg/ml against various pat...

Many of the health benefits associated with Aloe vera have been attributed to the polysaccharides contained in the gel of the leaves. These biological activities include effects promotion of wound healing, antifungal activity, hypoglycemic or antidiabetic effects, antiinflammatory, anticancer, immunomodulatory and gastroprotective properties. While the known biological activities of A. vera wil...

a low slope and a subcutaneous med of not less than 5 mg. Its oestrogenic activity intravaginally was not fully investigated, but is not high. It is weakly anti-oestrogenic in similar tests, with an med against oestradiol of about 200 \g=m\gsubcutaneously, perhaps a little lower intravaginally. No interactions were seen as they were with U-11100A\s=d\(Emmens & Martin, 1965). U-11555A has an ant...

During the past several years, nanotechnology based on novel nanomaterials has gained considerable attention in various scientific disciplines such as biotechnology, medicine and material engineering (McCarthy and Weissleder 2008). According to British Standards Institute Report (2007), nanoparticles are those particles with at least one dimension of less than or equal to 100 nm (1 nm = 1 x 10-...
