An adjustment method for spinal cord stimulators based on simplified gait analysis (1).

The use of electrical stimulators, for pain relief, spasticity reduction, and other applications, is greatly increasing; the programming facilities of the new devices extend the application range and allow to reduce the manufacturing costs. On the other side it is necessary to define methodologies and protocols for a custom setting of these devices. This work, although for only one patient, is a proposal for a methodology, based on a simplified gait analysis, for the adjustment of a spinal cord electrical stimulator.

Benzyladenine induces the appearance of LHCP-mRNA and of the relevant protein in dark-grown excised watermelon cotyledons.

Cotyledons were excised from imbibed watermelon seeds, grown for 4 days in darkness on water or 10 microM benzyladenine (BA) and then tested for the presence of the light-harvesting chlorophyll a/b protein (LHCP) and its mRNA. LHCP was assayed immunologically by western blotting of SDS gels: the protein was present in plastids, but it was not recovered with the thylakoid fraction. Antibodies directed against LHCP precipitated a 32 kDa polypeptide from translation products of poly(A) RNA of cotyledons only if these had been grown on BA. Taken together the data suggest that in absence of light cytokinins are necessary for the maintenance of a detectable level of LHCP-mRNA as well as for synthesis of the protein.

A flexible FFT algorithm for processing biomedical signals using a personal computer.

The aim was to demonstrate the possibility of using personal computer PC-DOS (or generally MS-DOS) for real-time (or quasi real-time) biomedical signal processing by adding a simple A/D conversion card and the mathematical coprocessor XXX87. We have realized an assembly written fast Fourier transform (FFT) routine derived from a radix-4 algorithm, which is autogenerated, i.e. an algorithm modified by another algorithm running off-line according to the number of FFT points. The program is implemented as a subroutine to be called upon by high-level language in different procedures. This approach reduces the computational time, which is particularly useful when many Fourier transforms on different data arrays are required. Reported here are two different applications of the routine as applied to the spectral analysis of Doppler ultrasound velocimetry and surface electromyography.
