1. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function
Abstract : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. READ MORE

2. Modulation of serous salivary gland function by the sympathetic nervous system : a biochemical and ultrastructural study with special reference to β-adrenoceptor subtypes
Abstract : The aim of the present investigation was to study the influence of the sympathetic nervous system and of various adrenoceptor agents on enzyme secretion and morphology in rat parotid and guinea-pig submandibular glands. Biochemical methods were combined with electron microscopical techniques. READ MORE

3. Autonomic nervous system regulation in chronic neck-shoulder pain : Relations to physical activity and perceived stress
Abstract : Neck-shoulder pain (NSP) is a highly prevalent musculoskeletal disorder with unclear causes, and effective prevention and treatment require a further understanding of the underlying mechanisms. Aberrant autonomic nervous system (ANS) regulation is a hypothesized causal element in the development and maintenance of chronic muscle pain. READ MORE

4. Zinc-enriched neurons in the spinal cord, cerebellum and peripheral sympathetic system
Abstract : Zinc ions are abundant in the nervous system and are involved in many biological functions. Most zinc is tightly bound to macromolecules, whereas a small fraction of zinc exists in synaptic vesicles of the zinc-enriched (ZEN) neurons, and can be visualized using various histochemical techniques, including autometallography (AMG).

5. Sympathetic function in cardiac disorders.Upon cardio-renal sympathetic activity and effects of nitroglycerin in human heart failure
Abstract : This study explores pathophysiological mechanisms and prognostic implications of sympathetic activation in patients with atherosclerotic renovascular hypertension (RVH) and with chronic heart failure (CHF). Hitherto, it is unknown whether cardiac sympathetic activation is present in patients with RVH, the presence of which could relate to the increased cardiovascular mortality observed in this disorder.
