(American Institute of Physics) Underwater wi-fi, music over the internet, pitch perception in the brain, discovering how whales find their favorite salmon, detecting dangerous swimmers, helping people who have undergone laryngectomy, rhythm and movement disorders, visualizing the sound of musical instruments and finding a possible way to save manatees from collisions with boats: These are a few of the topics that will be covered at the 156th Meeting of the Acoustical Society of America next month in Miami, Fla.

| • | Isolation, Characterization and Growth Response of Pesticides Degrading Bacteria |
| In Pakistan, insecticides are widely used in agriculture. Despite their biodegradable nature, some are highly toxic and their residues are found in the environment. Moreover, its removal from wastewater generated during manufacture becomes inevitable. Reports on the mineralization of a spectrum of different insecticides by a single potential strain are scarce. In this study, a bacterial strain was isolated from soil using enrichment technique and identified as Pseudomonas sp. by microscopic examination and biochemical tests. Growth curve experiments showed that Pseudomonas strain was able to grow in nutrient medium containing malathion (35-220 mg L-1), methamidophos (80-320 mg L-1), cartap (60-120 mg L-1) and cypermethrin (40-125 mg L-1) pesticide. However, the optimum concentration which support normal bacterial growth during 24 h was found to be 120 mg L-1 malathion, 160 mg L-1 methamidophos, 80 mg L-1 cartap and 60 mg L-1cypermethrin. When compared with the control test, a significant increased in bacterial population was noted at low concentration of each pesticide, however at high concentration lag phase increased but no zone of inhibition observed. These data indicate that the isolated Pseudomonas strain can be used as a microorganism for the bioremediation of pesticide contaminated soil or water. | |

| • | 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. | |
