OrCanome: a Comprehensive Resource for Oral Cancer
Bhartiya, Deeksha,Kumar, Amit,Singh, Harpreet,Sharma, Amitesh,Kaushik, Anita,Kumari, Suchitra,Mehrotra, Ravi Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.3
Oral cancer is one of the most prevalent cancers in India but the underlying mechanisms are minimally unraveled. Cancer research has immensely benefited from genome scale high throughput studies which have contributed to expanding the volume of data. Such datasets also exist for oral cancer genes but there has been no consolidated approach to integrate the data to reveal meaningful biological information. OrCanome is one of the largest and comprehensive, user-friendly databases of oral cancer. It features a compilation of over 900 genes dysregulated in oral cancer and provides detailed annotations of the genes, transcripts and proteins along with additional information encompassing expression, inhibitors, epitopes and pathways. The resource has been envisioned as a one-stop solution for genomic, transcriptomic and proteomic annotation of these genes and the integrated approach will facilitate the identification of potential biomarkers and therapeutic targets.

Characterizations of plasma sprayed composite coatings over 1020 mild steel
P. Vijayanand,Amitesh Kumar,K. R. Vijaya Kumar,A. Vinod,P. Kumaran,S. Arungalai Vendan 대한기계학회 2017 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.31 No.10
The present work deals with the coating of mild steel using plasma spray coating technique to improve surface properties for various industrial applications. Three different composite coating powders namely Al 2 O 3 :TiO 2 , Al 2 O 3 :TiO 2 : CNT and Al 2 O 3 : CNT were coated on the surface of mild steel for a thickness of 0.25 mm. Subsequently, the coated samples were tested for their mechanical characteristics namely tensile, compression and hardness followed by tribological investigations primarily comprising of wear analysis. Further, metallurgical analysis engrossing the Scanning electron microscopy, X-Ray diffraction and Energy-dispersive X-ray spectroscopy analysis were carried out to assess the homogeneity, spread uniformity and bond integrity of the developed samples. The test results revealed that the performance measure of Al 2 O 3 :TiO 2 : CNT is way ahead than other two powder coatings while carbon nanotube majorly contributes to the strength and quality of the surface coating.

The current study deals with the investigation on the performance characteristics of varying composition of coating mixture comprising carbon nano-tube, alumina and titanium dioxide on the thermal spray coating on mild steel. The performance properties, namely tensile and microhardness, were measured for the varying composition of coating mixture based thermal coating on mild steel. Response surface methodology was adopted to access the interdependencies prevailing between various dependent and independent parameters, namely composition of the mixture, tensile and microhardness. Scanning Electron Microscope coupled with elemental mapping were used to show the melting zones features and composition. The experimental results and response graphs indicated that increased weight percentages of carbon nano-tube and TiO2 with an optimal value of alumina at 87.5 percent of total weight showed better performance properties due to better dispersion leading to good bonding suitable for protective coatings. Scanning Electron Microscope images reveal partially melted zones that were restricted to smaller regions, and all particles tend to solidify beginning with a fully molten phase.
