(Wiley-Blackwell) A new article in the Journal of Law, Medicine & Ethics suggests that it is premature for states to currently mandate the HPV vaccine as a condition for school attendance.

| • | Isolation and Some Properties of New Xylanase from the Intestine of a Herbivorous Insect (Samia Cynthia Pryeri) |
| Xylan the major portion of the hemicellulose of plant cell walls are heterogeneous polysaccharides. Xylanases are enzymes obtained from different species of microorganisms that degrade the xylosidic linkages of xylans backbone producing xylose with other monoresidues. In this study, xylanase producing strains were isolated from intestine of a herbivorous insect at Rajshahi University Campus. The strains were isolated on xylan agar media and screened by -xylanolysis method. Zymogram analysis was confirmed the xylanolytic activity. The strains was identified to be Aeromonas sp. and xylanase enzyme was detected in the culture supernatant of the strain. Xylanase enzyme was purified from culture supernatant of Aeromonas sp. by ammonium sulfate precipitation, gel filtration on Sephadex G-100 followed by ion exchange chromotography on DEAE-cellulose. In DEAE cellulose column chromatography, three protein peaks F-1a, F-1b and F-1c were appeared. Among these peaks, only F-1b showed xylanase activity and the degree of purification attained 64.54 fold. The purified enzyme gave single band on SDS-polyacrylamide gel electrophoresis indicating its homogeneity. The enzyme gave maximum activity against xylan as substrate at pH 7.0 and temperature at 55C. The Km value of xylanase was found to be 0.91% using the oat spelt xylan as substrate. The xylanase hydrolyzed strongly oat spelt xylan and birch wood xylan but didnot hydrolyze cellulose, carboxymethyl cellulose and starch. Xylose was detected as the hydrolysis products of oat spelt xylan by the xylanase. | |

| • | Identification of restriction endonuclease with potential ability to cleave the HSV-2 genome: Inherent potential for biosynthetic versus live recombinant microbicides |
| Background: Herpes Simplex virus types 1 and 2 are enveloped viruses with a linear dsDNA genome of ~120?200 kb. Genital infection with HSV-2 has been denoted as a major risk factor for acquisition and transmission of HIV-1. Developing biomedical strategies for HSV-2 prevention is thus a central strategy in reducing global HIV-1 prevalence. This paper details the protocol for the isolation of restriction endunucleases (REases) with potent activity against the HSV-2 genome and models two biomedical interventions for preventing HSV-2.Methods and ResultsUsing the whole genome of HSV-2, 289 REases and the bioinformatics software Webcutter2; we searched for potential recognition sites by way of genome wide palindromics. REase application in HSV-2 biomedical therapy was modeled concomitantly. Of the 289 enzymes analyzed; 77(26.6%) had potential to cleave the HSV-2 genome in > 100 but < 400 sites; 69(23.9%) in > 400 but < 700 sites; and the 9(3.1%) enzymes: BmyI, Bsp1286I, Bst2UI, BstNI, BstOI, EcoRII, HgaI, MvaI, and SduI cleaved in more than 700 sites. But for the 4: PacI, PmeI, SmiI, SwaI that had no sign of activity on HSV-2 genomic DNA, all 130(45%) other enzymes cleaved < 100 times. In silico palindromics has a PPV of 99.5% for in situ REase activity (2) Two models detailing how the REase EcoRII may be applied in developing interventions against HSV-2 are presented: a nanoparticle for microbicide development and a "recombinant lactobacillus" expressing cell wall anchored receptor (truncated nectin-1) for HSV-2 plus EcoRII. Conclusion: Viral genome slicing by way of these bacterially- derived R-M enzymatic peptides may have therapeutic potential in HSV-2 infection; a cofactor for HIV-1 acquisition and transmission. | |
