The largest diabetic population in India is around 50.8 million that could reach an epidemic proportion by 2030. The most common chronic oral diseases encountered worldwide are the oral infections seen in diabetes like the dental caries, gingivitis and periodontitis. The aim of the present study is to investigate the prevalence of oral bacterial flora in the buccal cavity of Diabetes mellitus individuals and control. A total of 400 buccal samples were collected from diabetic and non diabetic individuals (200 buccal samples each). Nutrient agar was used for the primary isolation of bacterial species. Morphological, Biochemical and Phylogenetic characterization along with additional tests using selective and differential media were used for identification. Results revealed that the normal oral flora in diabetic individual were higher, compared to non diabetic individuals. Staphylococcus aureus was the most predominant bacteria followed by Streptococcus species in diabetic individuals. In-vitro anti microbial susceptibilitytesting was performed using Amikacin (30mcg), Amoxicillin (30mcg), Erythromycin(15mcg), Gentamicin (30mcg) and Tetracycline (30mcg). Results showed that the antibiotics used in the test were effective against the isolated bacterial species. In-vitro antimicrobial susceptibility testing is needed for proper management of the disease. Source

The present study reveals the phytochemical and mineral screening of Zanthoxylum tetraspermum W & A., a member of the family 'Rutaceae', which is used for treating microbial infections, antifungal activities and tooth ache. The preliminary screening of phytochemicals, thin layer chromatographic (TLC) profile of secondary metabolites and minerals from the stem bark of Zanthoxylum tetraspermum have shown the presence of various important secondary metabolites such as alkaloids, flavonoids, glycosides, Phenols, sterols, saponins, tannins in higher levels in hydroethnolic and aqueous extracts and some minerals in the plant extract. The generated data has provided the basis for its therapeutic value and can be used as a therapeutant. Source

The aim of this paper is to introduce and investigate a new decomposition of sets called πgμr-locally closed sets and a new decomposition of continuous maps called πgμr-LC continuous maps. Furthermore, we obtain several properties and characteristics of the new notions. © 2015 The Authors. Published by Elsevier B.V. Source

This paper proposes a content based color watermarking scheme based on block SVD and Arnold Transformation [1]. The main intention of watermarking system is to meet two conflicting objectives. They are robustness and transparency. DWT is used as a feature (Content based Watermark) to embed it in the host image. The watermark's pixel is embedded into the maximum singular value bit of each block obtained from the block SVD transformation of host image in each RGB channel. To increase the security, Arnold Transformation is used to watermark scrambling pretreatment. Experimental result shows the robustness of this scheme against common image processing operations such as JPEG compression, noise, rotation, rescaling, etc.., © 2014 IEEE. Source

The present investigation deals with the identification of phytochemical compounds present in chloroform and methanol extract of Piper longum and P. nigrum. It showed the presence of phytochemical constituents like tannins, terpenoids, and phenolic compounds, alkaloids and flavonoids. The total phenolic content was determined using the Foin-Ciocalteu assay and total flavonoids by the Aluminium chloride colorimetric assay. Percentage of phenol in mg equivalence of gallic acid of both the peppers in chloroform and methanol extract was same and the percentage of flavonoids in mg equivalence of Quercetine was high in both pepper species. In order to find out the chemical compounds GC-MS analysis was done. It showed the presence of 10-15 volatile compounds and it gave an integrated percentage of many compounds. The black pepper in chloroform contains 15 components, out of that highest integrated percentage of Aspartic acid were present. In the case of long pepper in chloroform extracts gave 14 components, out of that the highest integrated percentage of Micosporine and Graveoline were present. However further studies are focussed towards the importance of these compounds to prevent diseases. Source
