Identification of Helicobacter pylori and other Helicobacter species by PCR, hybridization, and partial DNA sequencing in human liver samples from patients with primary sclerosing cholangitis or primary biliary cirrhosis

Helicobacter pylori was identified in human liver tissue by PCR, hybridization, and partial DNA sequencing. Liver biopsies were obtained from patients with primary sclerosing cholangitis (n = 12), primary biliary cirrhosis (n = 12), and noncholestatic liver cirrhosis (n = 13) and (as controls) normal livers (n = 10). PCR analyses were carried out using primers for the Helicobacter genus, Helicobac

Brandspridning och brandförlopp i tät småhusbebyggelse : fire spread and fire development in low-rise residential building areas

This investigation makes a survey of the spread of fire and the fire development in low-rise residential building areas through obtaining the literal knowledge of factors having influence on a fire in one burning building and fire spread between buildings within a group of single-family houses. The purpose of the investigation was, on basis of the knowledge, to propose improved measures and the ch

Quality of life in the elderly population: an example exploring interrelationships among subjective well-being, ADL dependence, and housing accessibility.

During recent decades, research on quality of life has gained increasing interest. In gerontology, the assessment of objective as well as subjective dimensions is recommendable, and the most innovative research will involve the study of the interrelationships of several components. In empirical research objective environmental factors have rarely been explored. The aim of this study was to explore

Effects of pH, salt and time on ligand binding properties of overexpressed melanocortin 4 receptor.

The G-protein coupled melanocortin 4 receptor (MC4r) plays an important role in the energy metabolism. We overexpressed the MC4r in CHO cells and performed characterisation studies on the cell membranes to determine functional stability and ligand binding properties of the receptor. The affinity for the ligands [Nle4, Image-Phe7]-αMSH and MTII was lost below pH 6 but could be restored by returning

Relations between pig growth and regulatory mechanism of pancreas - facts and hypotheses

The aim of the mini review is to more precisely determine the relationship between exocrine pancreas function and the growth of young pigs. In order to do so, it is necessary to clarify the components, pathways and messengers involved in the CCK-dependent neuro-hormonal regulation of the exocrine pancreas in the growing pigs. These mechanisms are largely unknown, and the role of CCK has been quest

Placental histology and fetal blood flow in intrauterine growth retardation

OBJECTIVE. To define the histological lesions in the placenta associated with abnormal blood flow findings and to evaluate their possible clinical significance. DESIGN. A prospective blind study. SETTING. A clinical study at a teaching hospital, Malmo General Hospital, University of Lund, Sweden, morphological studies of placentas being performed at the Institute of Pathology, University of Lausan

First measurement of the helicity-dependent (gamma)over-right-arrow(p)over-right-arrow -> p eta differential cross-section

The helicity dependence of the (γ) over right arrow(p) over right arrow -+ peta reaction has been measured for the first time at a center-of-mass angle theta(eta)*= 70degrees in the photon energy range from 780 MeV to 790 MeV. The experiment, performed at the Mainz microtron MAMI, used a 4pi-detector system, a circularly polarized, tagged photon beam. and a longitudinally polarized frozen-spin tar

Lågdos-DT bättre än vanlig röntgen vid diagnostik av rinosinuit. Bör vara förstahandsval

Lågdos-DT (datortomografi) av näsans bihålor vid rinosinuit ger en god visualisering av samtliga näsans bihålor, även av etmoidal-, sfenoidal- och frontalsinus, där konventionell röntgenundersökning är förenad med stor osäkerhet. Lågdos-DT ger värdefull tilläggsinformation om både anatomi och patologiska förändringar, som inte kan erhållas med konventionell röntgenundersökning. Stråldosen till pat

High-spin Proton and Alpha-particle Emission as Probes for Nuclear Structure

During recent years the nuclear decay modes of discrete prompt proton and a-particle emission from (super)deformed high-spin states have been discovered in nuclei in the Vicinity of Ni-56. The latest news from experiments performed at EUROBALL and GAMMASPHERE regarding these decays are presented and discussed.

The meta-contrast technique: relationships with personality traits and cognitive abilities in a healthy male study sample.

The relationship between defensive strategies as measured by the Meta-Contrast Technique (MCT) and self-reported trait anxiety, trait aggression and defensiveness, as measured by the Karolinska Scales of Personality (KSP), was investigated in 83 healthy men. Further aims of the study were to describe and document how a healthy and demographically well defined group of subjects responded to the MCT

Travellers returning to Sweden with falciparum malaria: Pre-travel advice, behaviour, chemoprophylaxis and diagnostic delay

We have investigated pre-travel advice, behaviour, chemoprophylaxis and diagnostic delay in travellers returning to Sweden with falciparum malaria. Questionnaires were distributed to patients having been notified with falciparum malaria from 1994 to 2001. Of 408 notified patients, 237 (58%) returned the questionnaires; 62% were males and 43% above the age of 45 y. Africa was the travel destination

Virulence in mice of pneumococcal clonal types with known invasive disease potential in humans

Streptococcus pneumoniae isolates of serotypes 1, 4, 6B, 7F, 14, and 19F belonging to clonal types with known invasive disease potential in humans were used to infect C57BL/6 and BALB/c mice. Most isolates were able to colonize the nasopharynx for 7 days. One serotype 19F isolate of the clonal type ST162 had higher bacterial numbers than other isolates and clonal types of the same serotype. Seroty

Inhibition of Inducible Nitric Oxide Synthase Enhances Anti-tumour Immune Responses in Rats Immunized with IFN-gamma-Secreting Glioma Cells.

Interferon gamma (IFN-gamma) has successfully been used in immunotherapy of different experimental tumours. Mechanistically, IFN-gamma has extensive effects on the immune system including release of nitric oxide (NO) by upregulation of the inducible nitric oxide synthase (iNOS). NO has putative immunosuppressive effects but could also play a role in killing of tumour cells. Therefore, the aim of t
