Validity of time series kinematical data as measured by a markerless motion capture system on a flatland for gait assessment.

As a cost-effective, clinician-friendly gait assessment tool, the Kinect v2 sensor may be effective for assessing lower extremity joint kinematics. This study aims to examine the validity of time series kinematical data as measured by the Kinect v2 on a flatland for gait assessment. In this study, 51 healthy subjects walked on a flatland while kinematic data were extracted concurrently using the Kinect and Vicon systems.

Proliferative Lesions of the Endometrium of 50 Four-Toed Hedgehogs ( Atelerix albiventris).

Uteri from 50 four-toed hedgehogs ( Atelerix albiventris) with clinical signs of uterine disease were histopathologically examined. Sixteen animals (32%) were diagnosed with endometrial hyperplasia, 7 animals (14%) were diagnosed with endometrial polyp, and 27 animals (54%) were diagnosed with endometrial neoplasia. The mean ages of the animals with endometrial hyperplasia, polyp, and neoplasia were 28.

Age-dependency of the serum oxidative level in the senescence-accelerated mouse prone 8.

Systemic oxidative stress is considered to cause aging. In this study, to estimate the oxidative stress level in senescence-accelerated mouse prone 8 (SAMP8), we evaluated serum reactive oxygen species production and reduction capacity by measurement of Diacron-Reactive Oxygen Metabolites (d-ROM) and Biological Antioxidant Potential (BAP), respectively, with age. SAMP8 showed earlier increase of d-ROM value with age than SAM resistant 1 (SAMR1), the control strain.

Experimental analysis for the contribution of tooth vibration to production of sibilant /s/ ∼ measurement of sound and vibration ∼.

Sibilant /s/, one of unvoiced sounds, is believed to be produced by flow turbulence provoked by the impingement of a jet to anterior teeth. Although it would be possible that the impingement of a jet as well as pressure fluctuations behind the anterior teeth associated with flow turbulence make anterior teeth vibrate, whereby contributing to the production of sibilant /s/, no studies have focused on this aspect. The present study is designed to investigate the possibility that the vibration of teeth contributes to the production of sibilant /s/.
