Antimicrobial peptide Temporin-Ra was isolated from the skin secretions of marsh frog Rana ridibunda. Temporin-Ra was chemically synthesized and purified using RP-HPLC technique. The cytotoxicity of peptide on lung airway epithelial cell line (A549) and peripheral blood mononuclear cells (PBMC) was studied by MTT assay. Furthermore, the effect of(More)
Brevinin-2R is an antimicrobial peptide which has been isolated from the skin of the frog Rana ridibunda. The purpose of the present study was to examine the cellular cytotoxicity and inflammatory effects of brevinin-2R (B2R) on human lung epithelial adenocarcinoma cell line A549. The effects of different concentrations (5, 10, and 20 μg/ml) of B2R on the(More)
MALIGNANT tumours can either arise de novo in a peripheral nerve or infiltrate the nerve by mere proximity. In both instances the incidence of paralysis is high. The sequence of events leading to a paralysis in such circumstances have been variously attributed to the pressure on the nerve by the tumour alone, or in association with local ischaemia. However,(More)
Software clustering involves the partitioning of software system components into clusters with the goal of obtaining optimum exterior and interior connectivity between the components. Research in this area has produced numerous algorithms with different methodologies and parameters. In this paper, we propose a novel ensemble approach that synthesizes a new(More)
A dataset with diverse training data is essence of the hand gesture recognition research. Most of the benchmarked datasets are limited in the number of signers and/or the number of each gesture try, which often result in over-fitting and poor generalization. Overcoming this challenge is often achieved by collecting a large number of exemplars for each hand(More)
