2. 21. 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.

4. 22. 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.

5. 23. β-adrenergic regulation of glucose transporters

   Author : Olof Dallner; Tore Bengtsson; Jeffrey Pessin; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenergic receptors; glucose transporters; Physiology; Fysiologi; fysiologi; Physiology;

   Abstract : The transport of glucose across the plasma membrane is a fundamental mechanism to provide cells with its basic requirements for energy yielding processes. It is also vital for clearing glucose from blood into tissues, a process normally stimulated by the hormone insulin in mammals. READ MORE

6. 24. Role of caveolin-1 in brown adipose tissue

   Author : Charlotte L. Mattsson; Barbara Cannon; Paul Pilch; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caveolin; brown adipose tissue; metabolism; signaling; Physiology; Fysiologi; fysiologi; Physiology;

   Abstract : Caveolae are 50-100 nm invaginations in the plasma membrane. Caveolae and the protein caveolin-1 (Cav1) have been shown to be important in many signaling pathways in different cell types; however, in some cell types caveolae and Cav1 do not seem to affect the investigated signaling pathways.

7. 25. Acid transport through gastric mucus : A study in vivo in rats and mice

   Author : Mia Phillipson; Lena Holm; Henrik Sjövall; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; gastric acid; pH-sensitive microelectrode; mucus; mucosal blood flow; nitric oxide; intravital microscopy; laser Doppler flowmetry; Fysiologi; Physiology; Fysiologi; Physiology; fysiologi;

   Abstract : The gastric mucosa is frequently exposed to endogenously secreted hydrochloric acid of high acidity. Gastric mucosal defense mechanisms are arranged at different levels of the gastric mucosa and must work in unison to maintain its integrity. READ MORE
