  1. 1. Psychobiological functioning in mid-adolescent girls and boys Linkages to self reported stress, self-esteem and recurrent pain

    University dissertation from Stockholm : Department of Psychology, Stockholm University

    Author : Lisa Folkesson Hellstadius; Stockholms universitet.; [2014]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Adolescents; Cortisol; Alpha-amylase; Stress; Self-esteem; Recurrent pain; psykologi; Psychology;

    Abstract : Among adolescents, the day-to-day functioning of the hypothalamo-pituitary-adrenal-axis (HPA-axis) and of the autonomic nervous system (ANS) and their relationships with stress, subjective health complaints and psychological factors such as self-esteem, studied in naturalistic settings, have been largely unexplored. This thesis aimed to investigate the diurnal activity of the HPA-axis (Studies I & II) in terms of salivary cortisol and the ANS/SNS system (Study III) in terms of salivary alpha-amylase (sAA) in mid-adolescent girls and boys.

  2. 2. An alkaline active maltooligosaccharide forming alpha-amylase from Bacillus halodurans

    University dissertation from Suhaila Hashim, Department of Biotechnology, Box 124, SE- 221 00, Lund, Sweden

    Author : Suhaila Hashim; Lunds universitet.; Lund University.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk teknik; Biochemical technology; differential scanning calorimetry; soda lakes; Bacillus halodurans; alkaliphile; á-amylase;

    Abstract : The East African Rift Valley contains a number of soda lakes, which represent some of the most stable, naturally occurring alkaline environments on earth. Alkaliphilic microorganisms found in these habitats have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values for industrial applications.

  3. 3. An Alkaline Active Cyclodextrin Glycosyltransferase from an Alkaliphilic Bacillus agaradhaerens

    University dissertation from Rita Martins ([email protected]) or Dept. of Biotechnology, Chemical Center, Lund University

    Author : Rita Martins; Lunds universitet.; Lund University.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloning; characterization; purification; 16S rRNA gene analysis; screening; alkaliphiles; soda lakes; Bacillus agaradhaerens; cyclodextrins; cyclodextrin glycosyltransferase; alpha-amylase family; sequencing; immobilization; Biotechnology; Bioteknik;

    Abstract : Soda lakes represent the most stable naturally-occurring alkaline environments on Earth and harbour a diverse population of alkaliphiles. Alkaliphilic microorganisms have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values. READ MORE

  4. 4. Icodextrin metabolism in peritoneal dialysis : Clinical and experimental studies

    University dissertation from Stockholm : Karolinska Institutet, Department of Clinical Sciences

    Author : Elvia García López; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peritoneal dialysis; icodextrin; icodextrin metabolites; ultrafiltration; alphaarnylase activity; gel-filtration HPLC;

    Abstract : Icodextrin (ICO, or polyglucose) is an effective osmotic agent for peritoneal dialysis (PD) patients (pts). ICO is a soluble polymeric form of glucose with an average molecular 'weight range from 13,000 to 19,000 dalton. Glucose is absorbed from the peritoneal cavity by diffusion. READ MORE

  5. 5. Icodextrin metabolism in peritoneal dialysis : Clinical and experimental studies

    University dissertation from Stockholm : Karolinska Institutet, Department of Clinical Sciences

    Author : Elvia Garcia Lopez; Karolinska Institutet.; Karolinska Institutet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Icodextrin is a glucose polymer which is used as osmotic agent to provide sustained ultrafiltration (UF) during the long (8-16 hours) dwell in end-stage renal disease patients undergoing peritoneal dialysis (PD). The aims of this thesis were to study: the metabolism of icodextrin in the peritoneal cavity and in the circulation of PD patients and non-uremic rats, the role of alpha-amylase in its hydrolysis, and the rate of breakdown of a synthetic maltoheptaose (G7) ex vivo which we propose as a novel measure of amylase mediated oligosaccharide metabolism.
