BACKGROUND To analyze the association between TLR-4 Asp299Gly and Thr399Ile gene polymorphisms and chronic periodontitis in a sample of south Indian population. MATERIALS AND METHODS Genomic DNA was obtained from peripheral blood of 60 patients with chronic periodontitis and 60 periodontally healthy subjects. TLR-4 Asp299Gly and Thr399Ile gene(More)
AIM The aim of the present study was to evaluate the presence of Cytomegalovirus (CMV) and Epsteinbarr virus -1 (EBV-1)viruses in sub gingival plaque of chronic periodontitis (groupA), aggressive periodontitis patients (group B), periodontally healthy controls (group C) and to compare the clinical parameters between virus negative and positive sites in each(More)
Silver nanoparticles exhibit new optical properties, which are observed neither in molecules nor in bulk metals. In the present study silver nanoparticle colloid was produced by chemical reduction method of silver salt (silver nitrate AgNO3) solution. The silver nanoparticles were characterized by using UV-VIS spectrometer and Scanning Electron Microscope(More)
Residence time distribution (RTD) study of solids in a three-phase pilot-scale bubble column photoreactor has been carried out in order to provide data for the development of an artificial neural network model usable for process op-timisation. The experimental data indicated that the RTD of solids was a complex nonlinear function of gas and liquid(More)
We report a new approach for the synthesis of heterohexa- and heterodecametalates via the use of non-aqueous, microwave-assisted reaction conditions. The two novel molybdovanadates have been isolated and characterized in the solid and solution states using single-crystal X-ray diffraction, FT-IR, UV/Vis, multinuclear NMR spectroscopy, and ESI-MS. The(More)
AIM To determine the knowledge in cardiopulmonary resuscitation (CPR) process, preference for CPR, and desire to participate in end-of-life decision making amongst older hospitalised patients. METHOD We prospectively interviewed 100 participants above 65 years of age awaiting discharge from acute medical ward and collected demographics, knowledge of CPR(More)
