Histamine-containing enterochromaffin-like (ECL) cells are numerous in the gastric mucosa. They operate under the. control of gastrin. ECL-cell tumors (gastric carcinoids) may arise as a consequence of sustained hypergastrinemia. For reasons unknown, such tumors have a female preponderance both in laboratory animals and humans. The present study consisted of four experiments exploring the possibil

The Lepidoptera fauna of the Danish island of Anholt is surveyed, and 1160 species are recorded. Anholt is situated in Kattegat 44 km from Denmark and 47 km from Sweden. The history and environment of the island are briefly discussed, with special focus on the flora, and earlier studies of the Lepidopterera fauna of Anholt are dealt with. The present study is in first hand based on material collec

Abstract in UndeterminedThe Land-Use, Land-Use Change and Forestry (LULUCF) sector of the Kyoto Protocol requires New Zealand to monitor changes in the country’s carbon stocks, including those within indigenous forests. Podocarpus cunninghamii Colenso was, in pre-human times, a dominant tree species within the forests of the South Island high country. Anthropogenic disturbance, primarily fire, has

Although high-throughput studies of gene expression have generated large amounts of data, most of which is freely available in public archives, the use of this valuable resource is limited by computational complications and non-homogenous annotation. To address these issues, we have performed a complete re-annotation of public microarray data from human skeletal muscle biopsies and constructed a m

Anterior cruciate ligament (ACL) injuries are common, severe knee injuries that result in a high risk of developing knee osteoarthritis (OA) in the affected individuals. As proof of high impact forces applied to cartilage and bone at the time of injury, traumatic bone marrow lesions and osteochondral fractures, located predominantly in the lateral tibiofemoral compartment, are commonly associated

Calculated triplet excited state potential energy surfaces are presented for a set of three bis-tridentate Ru(II)-polypyridyl dies covering a wide range of room temperature excited state lifetimes: [Ru(II)(tpy)(2)](2+), 250 ps; [Ru(II)(bmp)(2)](2+), 15 ns; and [Ru(II)(dqp)(2)](2+), 3 mu s (tpy is 2,2':6',2 ''-terpyridine, bmp is 6-(2-picoly1)-2,2'-bipyridine, and dqp is 2,6-di(quinolin-8-yl)Fridin

The very young Wabar craters formed by impact of an iron meteorite and are known to the scientific community since 1933. We describe field observations made during a visit to the Wabar impact site, provide analytical data on the material collected, and combine these data with poorly known information discovered during the recovery of the largest meteorites. During our visit in March 2008, only two

Popular Abstract in Swedish Kroppens immunförsvar består av röda och vita blodceller som alla härstammar från blodbildande stamceller i benmärgen. Stamcellerna har den unika egenskapen att kunna producera alla typer av blodceller och upprätthålla produktionen hela livet ut. I princip all blodbildning (hematopoes) sker i benmärgen, förutom för T celler. Dessa är vita blodceller som produceras i thyhe hematopoietic development is a highly dynamic but tightly regulated process. The flexibility to produce blood cells through more than one route will allow the blood system to respond rapidly in stress situations such as infections. On the other hand, regulation of the blood system is required to prevent blood cells from uncontrolled proliferation that could result in leukemia or bone marrow fai

To investigate the genotype and phenotype in families with adenosine triphosphate-binding cassette, sub-family A, member 4 (ABCA4)-associated retinal degeneration.

Developing new and useful methods in asymmetric catalysis is of continuous importance. A current challenge is to address the imperatives of green chemistry, such that processes maximize resource-efficiency and minimize the generation of waste. To this end, this article discloses the potential of alpha-amino acids in the development of entropy-controlled and enantiodivergent Lewis acid catalysis. I

Cigarette smoke exposure increases the risk of stroke. However, the underlying molecular mechanisms are poorly understood. Endothelin system plays key roles in the pathogenesis of stroke. The present study was designed to examine if lipid-soluble (dimethyl sulfoxide-soluble) cigarette smoke particles (DSP) induces upregulation of contractile endothelin type B (ETB) receptors in rat cerebral arteri

We have studied the (110) GaAs surface of a structure containing ortho twins by cross-sectional scanning tunnelling microscopy and we have compared the experimental results with ab initio density functional theory calculations and STM simulations. Both experimentally and theoretically we find that the surface of different twin crystallites are significantly displaced with respect to each other, pa

Objectives. Objective signs of autonomic dysfunction (AD) have been reported in patients with primary SS (pSS) while the presence of associated symptoms has not been systematically studied. Therefore, the aims of this study were (i) to assess the presence and severity of various AD symptoms in pSS patients and (ii) to relate AD symptoms to other clinical features of pSS. Methods. Thirty-eight pSS

Abstract in Undetermined Heimann, M., Nordqvist, E., Rudner, M., Johansson, M. & Lindgren M. (2013). Associative learning measured with ERP predicts deferred imitation using a strict observation only design in 14 to15 month old children. Scandinavian Journal of Psychology 54, 33-40. Deferred imitation (DI) is an established procedure for behavioral measurement of early declarative-like memorie

A highly efficient anode for glucose biofuel cells has been developed by a combination of pyranose dehydrogenase from Agaricus meleagris (AmPDH) and cellobiose dehydrogenase from Myriococcum thermophilum (MtCDH). These two enzymes differ in how they oxidize glucose. AmPDH oxidizes glucose at the C(2) and C(3) carbon, whereas MtCDH at the C(1) carbon. Both enzymes oxidize efficiently a number of ot

Sepsis and invasive bacterial infection is a major cause of human disease and death worldwide. Streptococcus pyogenes is one of the major pathogens responsible for bacterial infections, which range from mild to severe and life threatening conditions. S. pyogenes contains a cell wall anchored M protein, which is an important virulence factor that can interact with many cells of the immune system. O

Popular Abstract in Swedish Introduktion Aggressivt antisocialt beteende utgör en stor utmaning för dagens samhälle, och undersökningar av vad som ligger bakom ett återkommande sådant beteende behövs för utvecklingen av våldspreventiva insatser. Syften & Metod Syftet med avhandlingen var att identifiera faktorer som samvarierar med återkommande aggressivt antisocialt beteende. De specifika måIntroduction Aggressive antisocial behavior is a major challenge to society, and studies on the determinants of its persistence are essential to the development of strategies to prevent violence. Aims & Methods The overall aim of the thesis was to establish covariates of persistent aggressive antisocial behavior in a population-based cohort and in clinically evaluated, prospectively followed,
