Abstract:

Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines. After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference inter

Abstract:

Factors affecting catecholamine levels in vitro were studied using the modified high pressure liquid chromatography method with electrochemical detection. Differential centrifugation showed that platelet-rich plasma contained significantly higher catecholamine levels than platelet-poor plasma. Serum samples had significantly higher catecholamine levels than plasma. Plasma or serum samples clotted with glass beads had significantly higher catecholamine levels than those without. Therefore, consistent results can only be obtained when catecholamine samples are spun at the same speed, either plas

Abstract:

Abstract Hypothermia deaths pose a difficult challenge from the medico-legal point of view because no specific traces are left on the cadaver to be examined post-mortem. The concentrations of urinary catecholamines, adrenaline and noradrenaline increase in various stressful situations including cold stress, and high levels have been considered to be suggestive of lethal hypothermia. There is, however, a need for a better hypothermia indicator. A potential candidate could be thrombomodulin (TM), an endothelially expressed protein whose plasma concentration has been shown to elevate in response

Plasma catecholamines have been measured in chronically adrenalectomised (ADX) ducks, in chronically adrenal denervated ducks (DNX), in their respective sham-operated controls (SH-adx, SH-dnx) as well as in intact ducks after 3 minutes forced submergence. The results showed that 100% of the plasma Epinephrine (EP) and 40 to 80% of plasma Norepinephrine (NE) released during the dive came from the adrenal glands. 20 to 60% of plasma NE came from endings of the autonomic vascular sympathetic nerves which are strongly stimulated during diving.

The beta-adrenoceptor pathway is the best characterised of human receptors and the transplanted heart offered the opportunity to evaluate the effects of various pathological states on beta-adrenoceptor density in the absence of local presynaptic neuronal influences. The sympathoadrenal system plays an important role in both health and disease anda detailed understanding of the pathophysiological sequelae of cardiac transplantation is necessary if clinical management is to have a rational basis. Controversy surrounds the question of whether the human heart remains sympathetically denervated and

Within this thesis we have explored several aspects of chromaffin cell and phaeochromocytoma tumour biology, including the specific expression of key sympathoadrenal markers such as the noradrenaline transporter (NAT), neuropeptide Y (NPY) and chromog

Abstract:

The cardiac ryanodine receptor (RyR2) is a Ca2+ ion channel found in the sarcoplasmic reticulum (SR), an intracellular membranous Ca2+ storage system. It is well known that a destabilization of RyR2 can lead to a Ca2+ flux out of the SR, which results in an overload of intracellular Ca2+; this can also lead to arrhythmias and heart failure. The catecholamines play a large role in the regulation of RyR2; stimulation of the Beta-adrenergic receptor on the cell membrane can lead to a hyperphosphorylation of RyR2, making it more leaky to Ca2+.
