  1. 1. Coffee Consumption in Relation to Osteoporosis and Fractures : Observational Studies in Men and Women

    Author : Helena Hallström; Karl Michaëlsson; Alicja Wolk; Anders Glynn; Olle Svensson; Uppsala universitet; []
    Keywords : Coffee; Tea; Caffeine; Bone mineral density; Osteoporosis; Fractures; Cohort studies;

    Abstract : During the past decades, the incidence of osteoporotic fractures has increased dramatically in the Western world. Consumption of coffee and intake of caffeine have in some studies been found to be associated with increased risk of osteoporotic fractures, but overall results from previous research are inconsistent.

  2. 2. Taurine and dopamine-related effects of ethanol. An experimental study in rodents

    Author : Lisa Ulenius; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Addiction; Alcohol; Caffeine; Nucleus accumbens; Microdialysis;

    Abstract : The reinforcing properties of alcohol (ethanol) are associated with activation of the mesolimbic dopamine system and the concomitant increase in dopamine in the nucleus accumbens (nAc). Changes in this system are thought to be a predominant underlying factor in promoting excessive alcohol intake and alcohol use disorder. READ MORE

  3. 3. Adenosine receptors and stress : studies using methylmercury, caffeine and hypoxia

    Author : Olga Björklund; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Adenosine; adenosine receptors; knock-out mice; methylmercury; caffeine; hypoxia; cobalt chloride;

    Abstract : Brain development is a precisely organized process that can be disturbed by various stress factors present in the diet (e.g. exposure to xenobiotics) as well as insults such as decreased oxygen supply. READ MORE

  4. 4. Importance of pharmacogenetic and environmental factors for variation in caffeine disposition : with special emphasis on CYP1A2, CYP2A6, NAT2 and XO

    Author : Natasa Djordjevic; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Inter-individual variation in response to drugs conveys considerable risk of either therapy failure or drug toxicity. Caffeine, as one of the most frequently used psychoactive substances in the world, is not an exception, and both lack of effects and adverse reactions have been observed after usual doses. READ MORE

  5. 5. Physiological roles of A1 and A2A adenosine receptors : studies using genetically modified mice

    Author : Jiang-Ning Yang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Adenosine receptors; genetically modified mice; preconditioning; tolerance; heart rate; body temperature; locomotor activity; caffeine;

    Abstract : Since adenosine receptors were identified and cloned, their roles in animals and humans have been extensively studied. Because pharmacological tools have limitations, we have used mice in which adenosine receptors have been deleted to further study their roles under physiological and pathophysiological conditions.
