1. 16. VLSI Architectures and Arithmetic Operations with Application to the Fermat Number Transform

   Författare :Lars-Inge Alfredsson; Ben Smeets; [email protected]; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The properties of arithmetic operations in Fermat integer quotient rings 2m+1, where m = 2t, are investigated. The arithmetic operations considered are mainly those involved in the computation of the Fermat number transform. LÄS MER

3. 17. Effects of Dehydration and Blockade of the Renin-Angiotensin System in the One-humped Camel (Camelus dromedarius)

   Författare :Mahmoud Al Haj; Fred Nyberg; Santi Spampinato; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood; biochemical analysis; catecholamine; colorimetric assay; cortisol; dehydration; dromedary camel; glutathione; hematological analysis; HPLC; insulin- like growth factor-1; losartan; plasma; receptors; radioimmunoassay; serum; Pharmaceutical Science; Farmaceutisk vetenskap;

   Sammanfattning : The one-humped or the dromedarian camel is a pseudo-ruminant mammal, well adapted to the hot and dry climates of the desert. Its ability to withstand torrid heat and extreme desiccation is of paramount importance to its survival. LÄS MER

4. 18. Design and synthesis of -turn peptidomimetics : Applications to angiotensin II

   Författare :Susanna Lindman; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; peptide synthesis; turn mimetics; molecular modelling; receptor binding affinity; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

   Sammanfattning : This study addresses the issue of how to convert peptides into drug-like non-peptides while retaining the biological activity at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. Small bioactive peptides are in most cases conformationally flexible molecules. LÄS MER

5. 19. Obstructive sleep apnea and cardiovascular morbidity

   Författare :Yüksel Peker; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea; cardiovascular; hypertension; coronary artery disease; hospitalization; cost utility; morbidity; mortality; secondary prevention; angiotensin II; CPAP;

   Sammanfattning : Obstructive sleep apnea (OSA) affects 24 % of middle-aged men and 9 % of women in USA but the treatment criterion, daytime sleepiness is reported by 17 and 22 % of these subjects, respectively. Some previous studies have suggested an association between OSA and cardiovascular disease (CVD), but the conclusions have been conflicting due to co-existing traditionally recognized risk factors.

7. 20. Regulation of ion transport in the gastrointestinal tract : aspects of early development

   Författare :Lena Grahnquist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Gastrointestinal transport; early development; ontogeny; ion; sodium; potassium; H ; K -ATPase; Na - K - 2Cl- cotransporter; barium-sensitive potassium channels; Na ; K -; ATPase; dopamine; angiotensin II; glucocorticoids; rat; human;

   Sammanfattning : Ion transport in the gastrointestinal tract is vital for cellular homeostasis and to ensure growth during ontogeny. We have therefore investigated the regulation and maturation of sodium, potassium and hydrogen transport in the gastrointestinal tract. Net jejunal sodium absorption is significantly higher in young as compared to adult rats. LÄS MER
