introduction: sox9 is a transcriptional activator which is necessary for chondrogenesis. sox6 are closely related to dna-binding proteins that critically enhance its function. therefore, to carry out the growth plate chondrocyte differentiation program, sox9 and sox6 collaborate genomewide. chondrocyte differentiation is also known to be promoted by glucocorticoids through unknown molecular mec...

Aerosol absorption in the lower troposphere over continental India was assessed using extensive measurements of the vertical distribution of absorption coefficients aboard an instrumented aircraft. Measurements were made from seven base stations during winter (November–December 2012) and spring (April–May 2013), supplemented by the data from the networks of surface observatories. A definite enh...

PURPOSE This is a proof-of-principle study investigating the feasibility of using late gadolinium enhancement magnetic resonance imaging (LGE-MRI) to detect left atrium (LA) radiation damage. METHODS AND MATERIALS LGE-MRI data were acquired for 7 patients with previous external beam radiation therapy (EBRT) histories. The enhancement in LA scar was delineated and fused to the computed tomogra...

In this paper, a novel light separator with contrast ratio enhancement but maintaining the optical efficiency of the DLP projection system is proposed. The main capability of the novel light separator is to direct the uncontrolled light away from the image system. The working theorem for the novel light separator is derived as well. Uncontrolled light is kept away from the image system by a tot...

Setting the speed of infusion drops in a manual manner is by adjusting clamp on set, where nurse must count number chamber at same time as looking watch. This makes setting subjective and cannot be shown with numbers. In addition, nurses monitor rate continuously. Therefore, it necessary to enhancement accuracy giving so that they can objective numbers done making instrument an optocoupler dete...

with the advancement of nanotechnology, high-atomic materials such as gold nanoparticles can be used to increase the amount of absorbed doses and use this property to eliminate cancer cells. In this study, the dose enhancement factor (DEF) derived from different concentrations of gold nanoparticles was calculated to show an increase in absorbed dose from gold nanoparticles. At first, a tissue e...
