Prof. K. Byrappa, obtained his Masterâ€™s degree from the University of Mysore with Distinction. He is involved in inter-disciplinary research worth of Rs. 75 Crores at the University of Mysore and has successfully guided 21 students for their Ph. D and about 8 scholars are currently working under his guidance. A renowned academician and researcher Prof. K. Byrappa has over 370 research publications in International journals with more than 6800 citations and is known as a world authority in hydrothermal technology.
ZnO Nanoparticles (NPs) were bio-hydrothermally synthesized and coated by ex situ technique on degummed silk fibers. Nanoparticle coated fibres were subjected for X-ray diffraction, Scanning Electron Microscopy and Energy Dispersive Spectroscopy. Both coated and/uncoated fibers were sterilized by autoclave and ethylene oxide (chemical sterilization). Effect of coating and sterilization on mechanical properties of fibers was evaluated by measuring its tensile strength. Antibacterial efficacy of coated fibers was assayed against Staphylococcus aureus. PXRD of uncoated and ZnO NPs coated fibers fairly differed, with former exhibiting highly amorphous nature and latter showing additional ZnO peaks at 34.42Â° and 36.41Â° corresponding to (002) and (101) planes with decreased amorphousness. SEM of coated and uncoated fibres showed spherical and agglomerated NPs on entire fiber surface and EDS confirmed presence of Zn. Coated fibers had significant improvement in tensile strength, measuring 2.2 N/m2 against 0.82 N/m2 of uncoated silk fibers. Heat generated due to autoclaving affected tensile strength of both coated and uncoated fibers detrimentally though coated fibers showed better thermal resistance. Antibacterial activity of coated fibers was excellent on day 2 (1.9 cm zone of inhibition), which gradually declined by 6th day showing that coated fibers have consistent antibacterial activity against S. aureus. Hence, coating with ZnO NPs caused improvement in mechanical properties and antibacterial properties of degummed silk fibers, which could be a potent biomaterial for biomedical applications, especially for surgical silk sutures with inherent antimicrobial activity.

Dental implants are found to be the best available option for single or multiple teethâ€™s replacements in past few decades In past few years the desire for aesthetics along with long term function of an implant have also increased In certain clinical scenario where teethâ€™s are lost due to trauma, physiological and pathological dentoalevolar diseases insufficient bone can be found in the region where dentoalveolar implants are planned which could influence the aesthetics and long term prognosis of the dental implants The principle of guided bone regeneration (GBR)can be applied for osseous defects and ridge augmentation The procedure is presented with the specific incision ,adequate flap design and the osteoconductuive and scaffolding bone substitutes with a barrier membrane for a healing period of 4-6months providing a sound osseous region for an dental implant.
