To analyze the lip movement of patients with cleft lip and palate in detail, we developed a novel technique to produce a range image from a video-based motion capture system, and a unique technique to analyze lip movements in detail three-dimensionally. The accuracy of the range image obtained from the present system was investigated using a positioning actuator with a high accuracy and a known object, and by comparisons with the range images produced from a laser scanner with a cast model of a face. The lip motions of six healthy adults during phonation was analyzed.

In this study, we report the design and development of a stable fluorescent probe that is selectively localized in the cytosol of Hela cells. We designed two probes, 1 and 2, with D-π-A (carbazole (Cbz)-vinyl-naphthalimide (NPI)) and A-π-D-π-A (NPI-vinyl-Cbz-vinyl-NPI) architecture, respectively. Probes 1 and 2 exhibit broad photoluminescence (PL) spectra ranging from green (550 nm) to far-red (800 nm) in solutions and aggregated states.

Nondilated left ventricular cardiomyopathy (NDLVC) is a newly defined category of cardiomyopathy. We sought to evaluate and compare the phenotype of NDLVC with DCM using cardiac magnetic resonance (CMR) imaging and to investigate the prognostic significance of these conditions. One hundred and fifty patients suspected of having cardiomyopathy referred for CMR were recruited.

Introduction: Visual Inspection with Acetic Acid (VIA) has been adopted for cervical cancer screening in Kenya and other Low-Middle Income Countries despite providing suboptimal results among HIV-infected women. It is mostly performed by nurses in health centers. Innovative ways of improving the performance of VIA in HIV-infected women are desired.

Background: There is no consensus on the association between final local kyphosis and residual back pain (RBP) after traumatic vertebral fracture. The aim of this study was to investigate whether there is an association between the final local kyphosis angle and RBP in patients with traumatic vertebral fractures at the thoracolumbar junction who underwent single posterior surgery with percutaneous pedicle screws and implant removal after fracture healing. A second goal was to determine the optimal cut-off value for the final local kyphosis angle with and without RBP.
