1. 1. Effects of adenosine and acetylcholine on the lacrimal gland

   Författare :Stina K. Carlsson; J. Peter Gierow; Sven Tågerud; Darlene Dartt; Linnéuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lacrimal gland; adenosine; adenosine receptors; signal transduction; exocrine secretion; tear film; dry eye; Sjögren’s syndrome; acetylcholine; mitogen activated protein kinase; p38; Cell biology; Cellbiologi; Ophtalmology; Oftalmologi; Cell and molecular biology; Cell- och molekylärbiologi; Cell biology; Cellbiologi; Molecular biology; Molekylärbiologi; Biomedical Sciences; Biomedicinsk vetenskap;

   Sammanfattning : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. LÄS MER

3. 2. Myocardial energy metabolism in ischemic preconditioning, role of adenosine catabolism

   Författare :Mohammad Kavianipour; Umeå universitet; []
   Nyckelord :Ischemic preconditioning; adenosine; purine nucleoside phosphorylase; microdialysis; pig; Medicine; medicin;

   Sammanfattning : Brief episodes of ischemia and reperfusion render the myocardium more resistant to necrosis from a subsequent, otherwise lethal ischemic insult. This phenomenon is called ischemic preconditioning(IP). LÄS MER

4. 3. Interaction between Adenosine and Angiotensin II in Renal Afferent Arterioles of Mice

   Författare :Enyin Lai; A. Erik G. Persson; Göran Bergström; Uppsala universitet; []
   Nyckelord :Physiology; adenosine; angiotensin II; afferent arteriole; calcium; nitric oxide; microperfusion; tubuloglomerular feedback; Fysiologi;

   Sammanfattning : Renal arterioles represent the most important effecter site in the control of renal perfusion and filtration. Adenosine (Ado), angiotensin II (Ang II) and nitric oxide (NO) interact in modulating arteriolar tone. The present work investigates the mechanism of this interaction. LÄS MER

5. 4. The Influence of the Adenosine A1-receptor on Tubuloglomerular Feedback and Renin Release

   Författare :Russell Brown; A Erik G Persson; Pontus Persson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; adenosine; tubuloglomerular feedback; renin release; blood pressure; micropuncture; Fysiologi; Physiology; Fysiologi;

   Sammanfattning : The kidneys play a vital role in the maintenance of extracellular fluid and electrolyte balance and blood pressure. Adenosine, acting through the adenosine A1-receptor (A1R), and nitric oxide have been implicated in several of the regulatory mechanisms in the kidney. LÄS MER

7. 5. Striatal adenosine A2A receptors

   Författare :Per Svenningsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :caffeine; adenosine; A2A receptors; dopamine receptors; striatum; basal ganglia; immediate early genes; c-fos; NGFI-A; DARPP-32; in situ hybridization;

   Sammanfattning : The nucleoside adenosine exerts a modulatory action in the central nervous system by activating G-protein coupled receptors. Four such receptors are cloned and pharmacologically characterized: A1, A2A, A2B and A3. Caffeine, the most widely consumed psychostimulant, acts as an adenosine receptor antagonist predominantly on the first two. LÄS MER
