    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; pancreatic β-cells; islets of Langerhans; glucose; Ca2 oscillations; Ca2 transients; potassium; ryanodine; caffeine; glucagon; cAMP; inositol 1; 4; 5-trisphosphate; fura-2; glycine; alanine; arginine; Ca2 channels; rats; lean mice; ob ob mice; leptin; Cellbiologi; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Oscillations in cytoplasmic Ca2+ concentration ([Ca2+]i) is the key signal in glucose-stimulated β-cells governing pulsatile insulin release. The glucose response of mouse β-cells is often manifested as slow oscillations and rapid transients of [Ca2+] i. LÄS MER

  2. 2. Prevention of Experimental Cataract Induced by UVR

    Detta är en avhandling från Uppsala : Uppsala universitet

    Författare :Martin Kronschläger; Uppsala universitet.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cataract; ultraviolet radiation; apoptosis; thioltransferase; caffeine;

    Sammanfattning : Cataract is the leading cause of blindness in the world and is defined by opacification of the normally transparent lens of the eye. The major avoidable cause of cataract is ultraviolet radiation (UVR), but no current strategies have been developed to prevent the onset of cataract. LÄS MER

  3. 3. Anti-epileptic and neuroprotective mechanisms by Topiramate and Levetiracetam evaluated in primary cultures

    Detta är en avhandling från Uppsala : Uppsala universitet

    Författare :Mikael Ängehagen; Göteborgs universitet.; Gothenburg University.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; calcium imaging; phosphorylation; kainate; glutamate; caffeine; cerebral cortex; hippocampus; field potentials; neurons; astrocytes;

    Sammanfattning : The aim of this thesis was to evaluate plausible intracellular mechanisms of action for antiepileptic drugs, Topiramate (TPM) and Levetiracetam (LEV), and to investigate if TPM possesses neuroprotective properties. The thesis is based on results from calcium imaging, immunohistochemical stainings, viability tests, and Western blot using primary cortical or hippocampal cultures, or hippocampal brain slices.

  4. 4. Risk factors and adverse pregnancy outcomes in small-for-gestational-age births

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Britt Clausson; Uppsala universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; Pregnancy; birthweight; fetal growth retardation; small-for-gestational age; maternal anthropometrics; genetic; caffeine; stillbirth; postterm pregnancy; birthweight standard; Obstetrik och kvinnosjukdomar; MEDICINE Surgery Obstetrics and women s diseases; MEDICIN Kirurgi Obstetrik och kvinnosjukdomar; Obstetrics and Gynaecology; obstetrik och gynekologi;

    Sammanfattning : The studies were undertaken to evaluate risk factors and outcomes in small-for-gestational-age (SGA) births, in cohort studies using the population-based Swedish Birth, Twin and Education Registers. A cohort study of pregnant women from Uppsala County evaluated the effect on birthweight by caffeine. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Helena Hallström; Uppsala universitet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coffee; Tea; Caffeine; Bone mineral density; Osteoporosis; Fractures; Cohort studies;

    Sammanfattning : 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.
