1. 6. Nitric oxide (NO) and carbon monoxide (CO): A novel class of messenger molecules regulating insulin and glucagon secretion

   Författare :Ragnar Henningsson; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carbon monoxide CO ; nitric oxide NO ; Nitric oxide synthase NOS ; Insulin and glucagon secretion; cyclic nucleotides; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi; Heme oxygenase HO ;

   Sammanfattning : During the last decade it has been shown that nitric oxide (NO) and carbon monoxide (CO) are produced in our own body, and that they constitute a novel class of messenger molecules. In 1992 a constitutive NO-producing NO-synthase (cNOS) was found in the islets of Langerhans, and in 1997 we could show for the first time that the islets also contained a CO-producing constitutive heme oxygenase (HO-2).

3. 7. The neuropeptides GRP and PACAP and the function of the endocrine pancreas - A study on receptor deficient mice

   Författare :Kristin Persson; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; hypoglycemia; glucagon; insulin; islet of Langerhans; diabetes; PACAP; neuropeptides; GRP; diabetologi;

   Sammanfattning : The parasympathetic nerves are important for the regulation of insulin secretion, in particular after meal intake. Apart from acetylcholine, several neuropeptides can be found in the parasympathetic nerves innervating the islets of Langerhans, including gastrin-releasing peptide (GRP) and pituitary adenylate cyclase activating polypeptide (PACAP).

4. 8. Trygghet i skärgårdsmiljö : En studie om rädsla för brott i Åboland

   Författare :Agneta Mallén; Sociologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Criminology; Åboland; Victimisation; Trust; Stranger; Social control; Shaming; Safety; Rural; Risk; Police; Moral minimalism; Gossip; Gemeinschaft; Gated community; Fear of crime; Established and outsiders; Drink driving; Archipelago; Community; Sociology; Åboland; Risk; Kriminologi; Sociologi;

   Sammanfattning : This study examines safety and fear of crime in Åboland, a predominantly rural area in southwestern Finland. It also examines crime and criminals in the area, as well as the distinctive social control that characterises Åboland's eight municipalities. LÄS MER

5. 9. GABA in the islets of Langerhans

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

   Sammanfattning : 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). LÄS MER

7. 10. Regulation of Islet Function by the Neuropeptide PACAP

   Författare :Karin Filipsson; Diabetes - molekylär metabolism; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; postprandial; calcium; sodium; cAMP; intracellular signaling; glucagon; insulin; Pituitary adenylate cyclase-activating polypeptide; PACAP receptors; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

   Sammanfattning : It is known that parasympathetic, sympathetic and sensory nerves innervate the islets and that these nerves harbor both classical neurotransmitters and neuropeptides. However, the neural influence on islet hormone release is complex and not yet fully understood A recently discovered pancreatic neuropeptide is pituitary adenylate cyclase-activating polypeptide (PACAP).
