Intestinal adaptation in atrophic rat ileum is accompanied by supersensitivity to vasoactive intestinal peptide, pituitary adenylate cyclase-activating peptide and nitric oxide

BACKGROUND: Intestinal inactivity leads to atrophic changes and concomitant alterations in the expression of neurotransmitters in the enteric nervous system. In atrophic rat ileum neurones expressing vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating peptide (PACAP) decrease in number while nitric oxide synthase (NOS) expressing neurones increase. Since little is known

The effect of nitrogen deposition on nitrification, carbon and nitrogen mineralisation and litter C : N ratios in oak (Quercus robur L.) forests

The present study addresses the question why there is a positive relationship between nitrogen deposition and potential net nitrogen mineralisation and nitrification in oak (Quercus robur L.) forest soils in south Sweden (Falkengren-Grerup et al., 1998), and how this is related to the carbon mineralisation. We tested three hypotheses based on European studies (Persson et al., 2000a,b) that postula

High-spin States and Shell-model Description of the Neutron-deficient Nuclei 90Ru and 91Ru

High spin states in the neutron deficient isotopes Ru90 and Ru91 have been studied in the 2p2n and 2pn exit channels of the reaction Ar-36 + Ni-58 using the 149 MeV Ar-36 beam at VICKSI and the OSIRIS array. By gating the gammagamma coincidences with evaporated neutrons and protons, excited states in Ru90 were identified for the first time and the level scheme of Ru-91 was extended. In both nuclei

Studies on the use of digital radiography for the assessment of periapical bone lesions

Popular Abstract in Swedish Bakgrund För att diagnostisera förändringar i käkbenet är röntgenundersökning av stor betydelse. En bendestruktion blir synlig i röntgenbilden först när relativt stor mängd ben försvunnit. Flera tidigare studier har visat att destruktionen inte ses förrän den påverkar den kompakta yttre delen av käkbenet. Andra studier har däremot visat att destruktionen kan ses tidigaThe aim was to study digital radiography and to evaluate the influence of image processing on digital dental radiographs for the assessment of periapical lesions. In four studies, artificial bone lesions were made periapically and interradicularly in the mandibular premolar and molar regions. In a clinical study, direct digital radiographic images depicting the periapical bone tissue of different

Forerunners in bi-gyrotropic materials

Forerunners (precursors) in linear, temporally dispersive, bigyrotropic materials are investigated with time-domain techniques. Bigyrotropic materials are characterized by 12 constitutive parameters (integral kernels). Specifically, the four susceptibility dyadics are all gyrotropic with a common gyrotropic axis. Pulse propagation along this axis is analyzed with dispersive (noncoupling) wave spli

The Taimyr fold belt, Arctic Siberia: timing of prefold remagnetisation and regional tectonics

Late Precambrian and Palaeozoic platform sediments from the Central-South Taimyr Peninsula (Arctic Siberia) are all remagnetised. The remagnetisation is prefold and is related to thermal remagnetisation caused by Taimyr Trap magmatism. The remagnetisation age is estimated to 220-230 Ma and, hence, is considerably younger than the ca. 251 Ma age for the main body of Siberian Trap flood basalts. The

Systerskap som politisk handling : Kvinnors organisering i Sverige 1968 till 1982

Popular Abstract in Swedish Den andra vågens kvinnorörelse uppstod i Sverige med Grupp 8 1968 under en växande antikrigsrörelse mot USA:s krig i Vietnam. En ny generation kvinnor gick ut på gatorna och krävde fri abort, gratis daghem, organiserade kampanjer mot kvinnors låga löner och sexuell exploatering. Med denna avhandling försöker jag för det första visa vad som karakteriserar den nya kvinnorThe second-wave women's movement emerged in Sweden with Group 8 in 1968, at the height of the anti-war struggle against the US war in Vietnam. A new generation of women took to the streets to demand free abortion, and free childcare, and to campaign against women's low pay and sexual exploitation. This thesis focuses on a number of women's groups? collective action and organising during a politica

Medication errors when transferring elderly patients between primary health care and hospital care

Objective: The aims were to evaluate the frequency and nature of errors in medication when patients are transferred between primary and secondary care. Method: Elderly primary health care patients (> 65 years) living in nursing homes or in their own homes with care provided by the community nursing system, had been admitted to one of two hospitals in southern Sweden, one university hospital and on
