  2. 1. Heart and lung function - in health and disease : methodological studies in clinical physiology

    Author : Sofia Erelund; Nina Sundström; Urban Wiklund; Sandra Arvidsson; Bengt Johansson; Carl-Johan Carlhäll; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical physiology; reference materials; ECG; dynamic spirometry; HRV; rheumatoid arthritis; cardiovascular disease; ischemic heart disease; Clinical Physiology; klinisk fysiologi;

    Abstract : The human heart and lungs constitute an intricate and dynamic system. Various clinical physiological examinations can be used to evaluate cardio-pulmonary function and identify abnormalities. Thus, it is important to understand how normal physiology presents, to be able to identify pathological findings. READ MORE

  4. 2. Aspects of aqueous humor dynamics : Studies in vivo and in vitro

    Author : Maria Samuelsson-Almén; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; Aqneous humor flow; intraocular pressure; adenylate cyclase; nonpigmented ciliary epithelium; pituitary adenylate cyclase-activating polypeptide; vasoactive intestinal polypeptide; dopamine; prostaglandin; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : The purpose of the present investigation was to study the effects of PGF2α-l-isopropylester, some neuropeptides, and pharmacological agents on aqueous humor dynamics and intraocular pressure (IOP) in vivo and on adenylate cyclase activity in the nonpigmented ciliary epithelium (NPE) in vitro.Pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) caused a dose-dependent increase in cAMP formation, indicating that the NPE contains receptors for PACAP and VIP coupled to adenylate cyclase activation.

  5. 3. Distensibility in Arteries, Arterioles and Veins in Humans : Adaptation to Intermittent or Prolonged Change in Regional Intravascular Pressure

    Author : Roger Kölegård; Ola Eiken; Toste Länne; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arterial stiffness; venous distensibility; venous flow characteristics; bedrest; pressure training; Physiology; Fysiologi;

    Abstract : The present series of in vivo experiments in healthy subjects, were performed to investigate wall stiffness in peripheral vessels and how this modality adapts to iterative increments or sustained reductions in local intravascular pressures. Vascular stiffness was measured as changes in arterial and venous diameters, and in arterial flow, during graded increments in distending pressures in the vasculature of an arm or a lower leg.

  6. 4. Studies on stress in African green monkeys (Cercopithecus aethiops) : Stress associated cortisol and prolactin levels, lymphocyte modulation and pathological changes in adrenal cortex, stomach and hippocampus in the African green monkey (C. aethiops)

    Author : Mbaruk Abdalla Suleman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; adrenal cortex; capture; confinement; cortisol; husbandry; housing; hippocampus; lymphocytes; prolactin; stomach; stress; wild; African green monkeys; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : African green monkeys (AGMs) are highly susceptible to captivity-induced stress. An investigation of spontaneous deaths of laboratory confined AGMs at the Institute of Primate Research, Nairobi, Kenya over a period of 7.5 years documented mild to severe gastric mucosal erosions and ulcers in 83 of 260 (32%) necropsies.

  7. 5. The Role of Dopamine-Metabolising Enzymes in Renal Sodium Handling. An Experimental Study in vivo

    Author : Cecilia Odlind; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; dopamine; kidney; sodium; MAO; COMT; rat; mice; RBF; oxygen; renal; L-dopa; DOPAC; entacapone; phenelzine; dopamine receptors; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : Dopamine (DA) has been shown to act as an intrarenal natriuretic hormone and defects in the renal DA system have been associated with some forms of hypertension. How the DA activity is upregulated durin- increased sodium intake is, however, unknown. READ MORE
