1. 1. Ethanol from lignocellulose : physiological effects of inhibitors and fermentation strategies

   Författare :Mohammad J Taherzadeh; Chalmers Univ of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acetic acid; Agents; Cellulose; Enzyme inhibition; Feedback control; Fermentation; Hydrolysis; Metabolites; pH; Physiology; Wood; Yeast; Dilute acid hydrolyzate; Inhibitors; Lignocellulose; Physiological effects; Saccharomyces cerevisiae; Ethanol;

   Sammanfattning : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). LÄS MER

3. 2. Lysophosphatidic acid : Physiological effects and structure-activity relationships

   Författare :Ulrika K. Nilsson; Samuel Svensson; Karin E. Bornfeldt; Linköpings universitet; []
   Nyckelord :Lysophospholipids pharmacology; physiology; structure-activity relationship; muscle; smooth; drug effects; myometrium; norepinephrine; epinephrine; signal transduction; MEDICINE; MEDICIN;

   Sammanfattning : Lipids havepreviously been considered primarily as building blocks of the cell membrane, but are now also recognized as important cell signaling molecules. Lysophosphatidic acid (LPA) is a glycerophospholipid consisting of a phosphate head group, a linker region, and a lipophilic tail. LÄS MER

4. 3. The effects of glucocorticoids on brown fat : physiological and molecular studies

   Författare :Ineke Luijten; Jan Nedergaard; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : Brown adipose tissue (BAT) is the main site for non-shivering thermogenesis in most mammals. The BAT-specific uncoupling protein-1 (UCP1) uncouples substrate oxidation from ATP production and hereby decreases metabolic efficiency. LÄS MER

5. 4. Lipoprotein lipase in hemodialysis patients and healthy controls : effects of heparin

   Författare :Birgit Näsström; Per-Ola Attman; Umeå universitet; []
   Nyckelord :dalteparin; dialysis; lipoprotein metabolism; LMWH; LPL; triglycerides; UFH; uremia; medicinsk och fysiologisk kemi; Medical and Physiological Chemistry;

   Sammanfattning : Mortality from cardiovascular disease in patients on chronic hemodialysis (HD) is 10 to 20 times greater than in the general population. One major risk factor is renal dyslipidemia, characterised by an impaired catabolism of triglyceride (TG)-rich lipoproteins with accumulation of atherogenic remnant particles. LÄS MER

7. 5. Human-Human and Human-Animal Interaction : Some Common Physiological and Psychological Effects

   Författare :Linda Handlin; Kerstin Uvnäs-Moberg; Mikael Ejdebäck; Maria Petersson; Eva Nissen; Bo Algers; Rebecca Johnson; Högskolan i Skövde; Sveriges lantbruksuniversitet; []

   Sammanfattning : The aim of the present thesis was to investigate hormonal and physiological effects in mothers during a breastfeeding session and in dogs and their owners in response to short-term interaction. In study one, sixty-six mothers receiving either exogenous oxytocin infusion and/or epidural analgesia (EDA) during labor or intramuscular oxytocin injection post partum were studied. LÄS MER
