    Notes: Abstract: The inclusive 2(3He,t) reaction has been studied at 2 GeV for energy transfers up to 500 MeV and scattering angles from 0.250 up to 40. Data are well reproduced by a model based on a coupled-channel approach for describing the NN and NΔ systems. The effect of final state interaction is important in the low energy part of the spectra. In the delta region, the cross-section is very sensitive to the effects of Δ-N interaction and ΔN → NN process. The latter has also a large influence well below the pion threshold. The calculation underestimates the experimental cross-section between the quasi-elastic and the delta peaks; this is possibly due to projectile excitation or purely mesonic exchange currents.

    Altered brain cholinergic enzymes activity in the genetically obese rat (1991)
    Springer
    Cellular and molecular life sciences 47 (1991), S. 833-835

    Notes: Summary Genetically obese male Zucker rats (fa/fa) and their lean littermates (Fa/-) were used in this experiment. Fourteen-week-old obese and lean littermates were sacrificed and choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) enzymes were assayed in specific brain regions. The assays of these enzymes indicate that obese animals and a significantly lower ChAT activity in the cerebellum, pons, and cerebral cortex and a significant increase in ChAT activity in the thalamus and hypothalamus. Meanwhile, the cerebral cortex, cerebellum, midbrain, thalamus and hypothalamus of the obese animals showed significantly higher AChE activity than their lean littermates. It was concluded from this study that obesity may be associated with changes in the enzymes of the brain cholinergic system.

    Technology assessment in healthcare: A means for pursuing the goals of biomedical engineering (1993)
    Springer
    Medical & biological engineering & computing 31 (1993), S. HTA3

    Keywords: Biomedical engineering ; Cost-effectiveness analysis ; Methodological rigour ; Policymaking ; Quality of life ; Technological innovation ; Technology assessment

    Notes: Abstract The goals of biomedical engineering include the improvement of health and life quality of mankind. However, the contribution of biomedical engineering to those worthy ends must be more clearly related. Biomedical engineers should become more active in demonstrating to policymakers and other parties in healthcare the value of the contributions of healthcare technology. Technology assessment (TA) is a form of investigation designed to identify and evaluate the implications of technologies so as to inform policymaking. Among the important trends in TA that should be of special interest to biomedical engineers are the increasingly higher methodological standards for accepting evidence from clinical investigations, and the use of quality-of-life measures for determining how technologies affect people's lives.
