  2. 21. Helicobacter pylori interference with the L-arginine/NO pathway in the upper gut

    Author : Charlotte Von Bothmer; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acid; bicarbonate; duodenal ulcer; Helicobacter pylori; host defence; mucosa; nitric oxide; nitric oxide synthase;

    Abstract : Helicobacter pylori causes chronic gastritis and sometimes peptic ulcers but the pathogenesis is not fully understood. H. pylori-infected individuals with duodenal ulcer have an impaired duodenal mucosal bicarbonate secretion (DMBS) in response to acid. NO is an important signalling molecule in the body. READ MORE

  4. 22. Staphylococcal induced inflammatory response in human monocytes: Analysis of factors involved

    Author : Eva Mattsson; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; interleukin-6; interleukin-beta; TNF-alfa; teichoic acid; Staphylococcus epidermidis; peptidoglycan; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Purified bacterial cell wall components peptidoglycan and teichoic acid were isolated from staphylococcal species S. aureus and/or S. epidermidis and tested for their ability to induce cytokine release from plastic-adherent human monocytes. READ MORE

  5. 23. GABA in the islets of Langerhans

    Author : Anna Wendt; Diabetes - öcellsexocytos; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; secreting systems; diabetologi; sekretion; Endokrinologi; Endocrinology; SLMV; paracrine regulation; LDCV; islets of Langerhans; autocrine regulation; GABA; diabetology;

    Abstract : GABA (γ-aminobutyric acid) is a well-known inhibitory neurotransmitter in the CNS. GABA is also present at high concentrations in the insulin-producing β-cells in the islets of Langerhans, but its function there is less clear. GABA is believed to accumulate in SLMVs (synaptic-like microvesicles). READ MORE

  6. 24. Neuronal release and function of nitric oxide in smooth muscle

    Author : Henrik H Iversen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Autonomic neurotransmission; gastrointestinal tract; nitric oxide; nitric oxidesynthase; smooth muscle; urinary tract.;

    Abstract : The aim of the present thesis was to study nitric oxide (NO) as an effector molecule in autonomic neurotransmission. The nitrergic transmitter was examined with regard to its pharmacological profile, stimuli of release, release pattern, and effects in gastrointestinal and urinary tract smooth muscle. READ MORE

  7. 25. Phylogenetics of the genus sorghum, genetic diversity and nutritional value of its cultivated species

    Author : Dickson Ng'uni; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Sorghum (Sorghum bicolor (L.) Moench) ranks fifth among cereal crops and second highest in production after maize in Africa particularly in the semi arid regions where it is a food security crop. READ MORE
