2. 1. Protein kinases in hormonal regulation of adipocyte metabolism

   Author : Christine Berggreen; Proteinfosforylering; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipocyte; PKB; AMPK; SIK3; insulin; catecholamines; lipolysis; lipogenesis; glucose uptake; de novo fatty acid synthesis; A769662; Akti; cAMP;

   Abstract : Abstract Along with liver and muscle tissue, adipose tissue helps maintain normal levels of glucose and lipids in the blood and has a very important role when it comes to storing lipids that can provide whole-body energy. After a meal is ingested, adipocytes take up glucose from the circulation and use it as a substrate for synthesis of new fatty acids (FAs) in a process known as de novo fatty acid synthesis, as well as for synthesis of glycerol.

4. 2. Innervation patterns and locally produced signal substances in the human patellar tendon : of importance when understanding the processes of tendinosis

   Author : Patrik Danielson; Sture Forsgren; Håkan Alfredson; Graham Riley; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; patellar tendon; innervation; tendinosis; tendinopathy; acetylcholine; catecholamines; muscarinic receptors; adrenergic receptors; Anatomy; Anatomi;

   Abstract : Tendinosis is a condition of chronic pain that afflicts several human tendons, not least the patellar tendon, in which case it is often clinically referred to as ‘jumper’s knee’. The exact mechanisms behind tendinosis are yet not fully understood. READ MORE

5. 3. Development of central catecholaminergic neuronal systems in the lizard Anolis sagrei

   Author : Agneta Rehn; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; double labelling; immunohistochemistry; interplexiform cells; amacrine cells; catecholamines; development; retina; Reptiles; brain; Zoology; Zoologi;

   Abstract : Catecholamines, comprising the neurotransmitters dopamine (DA), noradrenaline (NA) and adrenaline (A) are synthesized by specific enzymes (tyrosine hydroxylase (TH), dopamine ß-hydroxylase (DBH), phenylethanolamine-N-methyltransferase (PNMT)) in the central nervous system. The development and distribution of different catecholaminergic systems have been described in both the brain and retina of the lizard Anolis sagrei. READ MORE

6. 4. New Approaches for Chemical Analysis of Single Cells and Vesicles

   Author : Johan Dunevall; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrochemistry; Analytical chemistry; Chemistry; Exocytosis; Catecholamines;

   Abstract : Exocytosis is the major cell-to-cell communication process in the nervous system, involving the conversion of an electrical signal (e.g. action potential) to a chemical one. Signaling molecules like neurotransmitters, hormones and/or peptides are stored in vesicles inside the cell. READ MORE

7. 5. Atrial Fibrillation after Coronary Artery Bypass Surgery : A Study of Causes and Risk Factors

   Author : Lena Jidéus; Dan Lindblom; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Atrial fibrillation; catecholamines; coronary artery bypass surgery; heart rate variability; neuropeptides; premature atrial contraction; thoracic epidural anaesthesia; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

   Abstract : The aim was to study pathophysiological mechanisms and risk factors for developing atrial fibrillation (AF) after coronary artery bypass grafting (CABG), and the effect of thoracic epidural anaesthesia (TEA).The study comprised 141 patients undergoing CABG, including 45 patients randomised for TEA intra- and postoperatively.
