Phytochemical constituents present in the aqueous and ethanolic extract of Syzygium cumini seeds were investigated which were found to be responsible for its medicinal efficacy. The major phytoconstituents present in S. cumini seeds were further determined by GCMS analysis which showed the presence of polyphenols, sesquiterpenes, n-alkanes. The antibacterial activity of ethanolic extract of S. cumini seeds were tested against common human pathogens by agar well diffusion method and minimum inhibitory concentration required to inhibit the growth of various pathogens were also evaluated. The seed extract was found to have high antibacterial activity. The total polyphenolic content of the ethanolic extract of S. cumini seed was determined by Folin-Ciocalteau method. The antioxidant activity of S. cumini seed ethanolic extract was evaluated by DPPH free radical scavenging assay, reducing power assay and total antioxidant capacity. S. cumini seed extract was found to have very high and potent antioxidant activity and might be due to the presence of high phenolic components in seed. The cytotoxicity assay of S. cumini seed ethanolic...

Mycobacterium tuberculosis is a deadly infectious disease, there is rising death of humans every year because of this disease, availability of genome sequences of Mycobacterium tuberculosis has provided tremendous amount of information that can be useful in drug target and new vaccine development. Sequence similarity provides accurate annotation for genes in newly sequenced genomes. In this present work about 107 hypothetical proteins of Mycobacetrium tuberculosis were taken and its functions were predicted using bioinformatics tools BLAST, BLOCKS, COGs, InterProScan and PFP. From our analysis of 107 hypothetical proteins only two shows 100% functions these proteins may serve as target for few...

In the present experiment effect of electroplating industrial effluent chromium on the behavioral responses of freshwater air-breathing cat fish Mystus cavasius was studied. The toxicity of chromium to aquatic life is strongly influenced by the form of chromium and quality of water. The two most prevalent chromium forms found in plating industry waste water are hexavalent chromium (Cr+6) and trivalent chromium (Cr+3). The fishes exhibited various behavioral responses – locomotory, physiological, neurological and morbidity responses under influence of chromium industrial effluent. One of the major advantages of using data on behavioral effects is that they are more sensitive indicators of potential for impacts on survival in the filed than are measures of lethality. Study noted the possible utility of the behavior responses as rapid biomonitory assessment technique for qualitative evaluation of various industrial...

Nowadays there has been considerable interest in developing new routes alternative to injection for delivering macromolecules such as proteins and peptides. However, peptides and protein drugs are degraded before they reach the blood stream and can not cross the mucosal barrier. The mucoadhesive polymer coated nanoparticles can solve these problems. They were prepared by emulsion polymerization. Methyl methacrylate polymerized in the presence of polysaccharide such as carbapol leads to formation of mucoadhesive polymer coated nanoparticles. The mucoadhesive polymers could interact with the mucus glycoproteins which allow the mucoadhesive system to remain adhesive for an extended period of time. Coating nanoparticles with them improved their mucoadhesion. These mucoadhesive polymer coated nanoparticles are suitable for carrying hydrophilic drugs. In present study carbapol coated nanoparticles are prepared by emulsion polymerization technique. Particle size was measured by Scanning electron Microscope. The effect of polymer concentration and chemical initiator concentration on the resultant nanoparticles was...

The study is aimed towards studying synergistic antimicrobial effect of cow urine and Azadirachta indica against bacterial, fungal and yeast strains. Mother Nature is the best healer. Last few decades have seen tremendous development in pharma sector. Even though these industries have produced a large number of new drugs and new antibiotics and so does the resistance among microbes is growing. Bacterial strains used were Streptomyces aureofaciens (MTCC 325), E.coli (MTCC 448), Streptococcus mutans (MTCC 497) and Pseudomonas aeruginosa (MTCC 7093). Fungal strains used were Candida albicans (MTCC183) and yeasts like Candida paraopsilosis (MTCC 1965), Candida tropicalis (MTCC 184), and Candida glabrata (MTCC 3019). When equilibrated amount of cow urine is used with Azadirachta indica remarkable synergistic effects were observed in the case of C. tropicalis, C. glabrata, P. aeruginosa, S. aureofaciens....
