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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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). READ MORE

  3. 3. Adenosine Regulation of Neutrophil Function

    Author : Stefan Zalavary; Bertil Fredholm; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The neutrophil granulocyte is an essential component of the human immune system. When rrricrobes invade the body, the highly motile neutrophils quickly leave the vascular compartment and approach, engulf and kill the intruders by releasing a battery of antimicrobial substances.

  4. 4. Mechanisms of Ischemic Brain Injury- studies in murine hippocampal slice cultures

    Author : Anna Rytter; Sektion IV; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; neuropsykologi; neuropsychology; Neurology; adenosine; caspases; hypothermia; in vitro; hippocampus; ischemia; neurofysiologi;

    Abstract : Cerebral ischemia is a major cause of mortality and morbidity in the western world. Even though much effort has been put into research and development of effective drugs against ischemic damage there is to date no effective pharmacological brain protective treatment. READ MORE

  5. 5. Vardenafil and methylarginines in pulmonary hypertension

    Author : Anna Sandqvist; Gerhard Wikström; Jörn Schneede; Amrita Ahluwalia; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; vardenafil; pulmonary hypertension; pharmacokinetics; haemodynamics; right heart catheterization; adenosine; dimethylarginines; phosphodiesterase type 5 inhibitors; endothelin receptor antagonists; klinisk farmakologi; Clinical Pharmacology;

    Abstract : Background: Pulmonary hypertension (PH) is a rare condition characterized by endothelial dysfunction and vascular remodelling, leading to increased pulmonary vascular resistance (PVR) and right ventricular heart failure. Endothelial dysfunction is associated with an imbalance between vasoconstrictor compounds, such as endothelin and thromboxane A2, and vasodilator compounds, such as prostacyclin and nitric oxide (NO).
