Background The importance of the somatosensory information from the plantar foot area for balance control is well reported in the literature. Usually, tests for touch and vibration sensitivity are performed with subjects in sitting or supine position [1]. However, balance tests are measured in standing position [2]. Therefore the aim of this study was to compare vibration thresholds measured wi...

We have discovered that intracellular redox state appears to be a necessary and sufficient modulator of the balance between self-renewal and differentiation in dividing oligodendrocyte-type-2 astrocyte progenitor cells. The intracellular redox state of freshly isolated progenitors allows prospective isolation of cells with different self-renewal characteristics. Redox state is itself modulated ...

the graphical technique for nonlinear circuits was described that enable us to optimize circuits to obtain maximum output power, maximum efficiency or minimum intermodulation. according to this method a high power amplifier in the ka band was designed. using a nonlinear model of the transistor, optimum slope for load-line was determined so that maximum power at the output was obtainable, then ...

OBJECTIVE To correlate disease duration in spinocerebellar ataxia type 2 (SCA2) with disease severity, balance and functionality. METHOD Sixteen SCA2 patients were analyzed for: disease duration, disease severity (SARA score), balance (Berg balance scale score) and functionality (FIM and Lawton scores). RESULTS Greater severity was correlated with worse functionality (Lawton: r = -0.0561, F...
