Nanotechnology advances towards development of targeted-treatment for obesity

Obesity through its association with type 2 diabetes (T2D), cancer and cardiovascular diseases (CVDs), poses a serious health threat, as these diseases contribute to high mortality rates. Pharmacotherapy alone or in combination with either lifestyle modifcation or surgery, is reliable in maintaining a healthy body weight, and preventing progression to obesity-induced diseases. However, the anti-obesity drugs are limited by non-specifcity and unsustainable weight loss efects. As such, novel and improved approaches for treatment of obesity are urgently needed. Nanotechnology-based therapies are investigated as an alternative strategy that can treat obesity and be able to overcome the drawbacks associated with conventional therapies. The review presents three nanotechnology-based anti-obesity strategies that target the white adipose tissues (WATs) and its vasculature for the reversal of obesity. These include inhibition of angiogenesis in the WATs, transformation of WATs to brown adipose tissues (BATs), and photothermal lipolysis of WATs. Compared to conventional therapy, the targeted-nanosystems have high tolerability, reduced side efects, and enhanced efcacy. These efects are reproducible using various nanocarriers (liposomes, polymeric and gold nanoparticles), thus providing a proof of concept that targeted nanotherapy can be a feasible strategy that can combat obesity and prevent its comorbiditie

Two days National Conference -VISHWATECH 2014 A Review-FPGA Implementation of Different Steganographic Technique

Abstract: Steganography is a method of hiding the information in a cover in such a way that only intended recipient can know that there is a hidden message. In Steganography for hiding informat ion any embedding mediu m can be used, called as carriers. These carriers can be images, audio files, video files, and text files. In this paper we have focused on steganographic techniques for image files. Image steganography techniques now days developed with an alternative approach based on an embedded FPGA system for image processing. Due to its reconfigurable ability Various FPGA approaches are chosen and without requiring hardware change-out, the uses of FPGA type Dev ices expand the product life by updating data stream files
