Surface EMG signals were recorded at 10, 20, 30, and 80% MVC from the flexor and abductor pollicis brevis muscles of five
patients with CTS and five control subjects. Subjects with severe CTS showed different interference IPI145 patterns, lower signal amplitude, lower neuromuscular efficiency, and lower myoelectric manifestations of fatigue with respect to the control group. At submaximal levels, action potentials recorded from the flexor and abductor pollicis brevis muscles of the CTS group were characterized by lower conduction velocity and lower mean spectral frequency than the healthy group. These findings support, among others, the hypothesis of a selective loss of fast motor units (type II fiber) associated with CTS.”
“Implanting fiducial markers for
localization purposes has become an accepted practice in radiotherapy for prostate cancer. While many correction strategies correct for translations only, advanced correction protocols also require knowledge of the rotation of the prostate. For this purpose, typically, three or more markers are implanted. Elongated fiducial markers provide more information about their orientation than traditional round or cylindrical markers. Potentially, fewer markers are required. In this study, we evaluate the effect of the number of elongated markers on the localization accuracy of the prostate. To quantify the localization error, we developed a model that estimates, at arbitrary locations in the prostate, the registration error caused by translational and rotational uncertainties of the marker registration. Every combination of one, two and three markers was analysed for a group of 24 patients. The average registration errors at the selleck inhibitor prostate surface were 0.3-0.8 mm and 0.4-1 mm for registrations on, respectively, three markers and two markers located on different sides of the prostate. Substantial registration errors (2.0-2.2 mm) occurred
at the prostate surface contralateral to the markers when two markers were implanted on the same side of the prostate or only one marker was used. In conclusion, there is no benefit in using three elongated markers: two markers accurately localize the prostate if they are implanted at some distance from each other.”
“The present study was to investigate the in vitro antioxidant potential of hot water extract and its fractions from dichloromethane (CH(2)Cl(2)), ethyl acetate (EtOAc), n-butanol Autophagy Compound Library purchase (n-BuOH), and water (H(2)O) of castor-aralia (Kalopanax pictus) leaves using different antioxidant tests. Among these crude extract and fractions, EtOAc fraction exhibited higher antioxidant potency than others in 1, 1-diphenyl-2-pricylhydrazyl (DPPH) free radical scavenging, reducing power assay, and reactive oxygen species (ROS) scavenging activity. However, CH(2)Cl(2) fraction showed higher hydroxyl radical scavenging and DNA damage protective activity. This work demonstrates the potential of castor-aralia leaves as antioxidant functional food ingredients.”
