p13 gene was first described in Leucania separata multinuclear polyhedrosis virus (Ls-p13) several years ago, but the function of P13 protein has not been experimentally investigated to date. In this article, we indicated that the expression of p13 from Heliothis armigera single nucleocapsid nucleopolyhedrovirus (Ha-p13) was regulated by both early and late promoter. Luciferase assay demonstrated that the activity of Ha-p13 promoter with hr4 enhancer was more than 100 times in heterologous Sf9 cells than that in nature host Hz-AM1 cells. Both Ls-P13 and Ha-P13 are transmembrane proteins. Confocal microscopic analysis showed that both mainly located in the cytoplasm membrane at 48 h. Results of RNA interference indicated that Ha-p13 was a killing-associated gene for host insects H. armigera. The AcMNPV acquired the mentioned killing activity and markedly accelerate the killing rate when expressing Ls-p13. In conclusion, p13 is a killing associated gene in both homologous and heterologous nucleopolyhedrovirus. [BMB Reports 2012; 45(12): 730-735]
The diathermy scratch pad: A cheap and efficient tool for chemical and explosion-related burns
Allen Wei-Jiat Wong,Qi En Hong,Cheryl Li Yu Hui,Si Jack Chong 대한성형외과학회 2019 Archives of Plastic Surgery Vol.46 No.1
The burn center in our hospital is a national and regional (Southeast Asia) center. Of all admissions, 10% are related to blast explosions, and 8% due to chemical burns. In the acute burn management protocol of Singapore General Hospital, early surgical debridement is advocated for all acute partial-thickness burns. The aim of early surgical debridement is to remove all debris and unhealthy tissue, preventing wound infection and thereby expediting wound healing. In chemical burns, there can be stubborn eschars that are resistant to traditional debridement. We would like to present a novel technique using the diathermy scratch pad as a cheap and efficient tool for the dual purpose of surgical debridement and dermabrasion.

The solvent-free modification of butyl rubber in the medium of NaH
Ying Feng,Yan Xia Wang,Hong Qi Shao,En Hua Zhang,Zhen Wang,Jiruo Zhao 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.1
A novel improved butyl rubber (PMIIR) was prepared in a solvent free process, using sodium hydride(NaH) as activating agent and maleic anhydride (MAH) as modifier by processing modificationtechnology in a conventional polymer processing equipment of an internal mixer. The structure ofproducts was characterized by 1H NMR and FT-IR. In this process, polar sodium carboxylate functionalgroup and unsaturated carbon–carbon double bonds were successfully introduced onto the chains of IIRon one step. The reaction mechanism was investigated in detail. It was found that the functionalizationexperienced two modified mechanisms: addition and substitution modified mechanisms. The reactionefficiency and content of MAH were evaluated. Polymer isolation and purification operations werereduced out due to the result of solvent free. Curing and mechanical properties of products wereinvestigated. It was found that PMIIR has greatly increased curing rate due to the incorporation of polargroup and carbon–carbon double bond.
