The high scattering and absorption of opaque tissues limit the penetration of light into deep tissues, limiting the imaging depth of various optical imaging techniques. The proposed tissue optical clearing technique provides an innovative way to perform deep-tissue imaging. Recently, various optical clearing methods have been developed. They result in tissue clearing with similar physical principles but differe...

No. of bitstreams: 0 Previous issue date: 2018-06-01; Wellcome Trust; Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successfu...
Background Raised blood pressure is an important risk factor for cardiovascular diseases and chronic kidney disease. We estimated worldwide trends in mean systolic and mean diastolic blood pressure, and the prevalence of, and number of people with, raised blood pressure, defined as systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher. Methods For this analysis, we poo...
Background Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults. Methods We pooled 2416 population-based s...
A reactive infiltration processing of SiC/Fe-Si composites using preforms made of coked rice husks (RHs) and SiC powder in different ratios is reported, in which FeSi2 alloy was used as infiltrant. The preforms were heat-treated at 1550 degrees C for 6 h prior to the infiltration. The coked RHs, which are composed of SiO2 and C, were converted to SiC and poorly crystallized C by carbothermal reduction during th...
