Ursolic acid (UA) is a pentacyclic triterpenoid, with anti-cancer and anti-inflammatory properties. Sphingomyelin (SM) hydrolysis generates lipid messengers regulating cell survival. Earlier studies showed that UA has anti-proliferative and apoptotic effects on HT29 cells, accompanied by a rapid increase in alkaline sphingomyelinase (Alk-SMase) activity. This study examines the effect of orally ad
The present study investigates attitudes towards aspects of health promotion in mental health services, as rated by patients and staff. The aim of the study was to investigate similarities and differences in attitudes towards health promotion interventions among patients and staff in mental health services, using a newly developed questionnaire, the Health Promotion Intervention Questionnaire (HPI
While the persistence of socioeconomic differences in cardiovascular disease (CVD) has been recognized for many years, less is known about whether socioeconomic factors are of importance to CVD before symptoms of the disease appear. In this study the associations among educational level, occupational status and progression of atherosclerosis were investigated in 1016 Swedish middle-aged men and wo
Cytoplasmic protein-tyrosine kinases (PTKs) are enzymes involved in transducing a vast number of signals in metazoans, The importance of the Tec family of kinases was immediately recognized when, in 1993, mutations in the gene encoding Bruton's tyrosine kinase (Btk) were reported to cause the human disease X-linked agammaglobulinemia (XLA).((1,2)) Since then, additional kinases belonging to this f
The palynological content of randomly collected sedimentary rock clasts from the till on the south-east slope of the Basen nunatak in northern Vestfiella in western Dronning Maud Land indicate that these sedimentary rocks were derived from strata of Middle Permian age. The palynological content and preservation is similar to palynofloras described from the sedimentary rocks that crop out at the Fo
The presence of hypertension aggravates the high cardiovascular risk in type 2 diabetic patients. Pulse pressure is a marker of arterial stiffness and constitutes a risk factor for cardiovascular mortality. This study examines the relationship between different blood pressure indices and mortality in a cohort of type 2 diabetic patients. A total of 1294 type 2 diabetic patients with a median age o
The effect of adaptation time on the concentration and pattern of short-chain fatty acids (SCFA) formed in the hindgut of rats given resistant starch (RS) in the form of raw potato starch (RPS) or high-amylose maize starch (HAS) was evaluated. Each starchy material was tested in diets containing 100 g indigestible carbohydrates/kg DM, and fed for 13, 28 and 42 d. At the end of each period, the con
In a 7-week-old infant who experienced sudden infant death syndrome (SIDS), a novel missense mutation was identified in KCNH2, causing a lysine-to-glutamic acid amino acid substitution at position 101 (K101E). KCNH2 codes for the HERG ion channel and mutations in the gene are associated with congenital long-QT syndrome (LQTS), and in the family of this case of SIDS, the mutation was associated wit
INTRODUCTION: A diet containing a high amount of fat has been shown, in short-term studies, to increase the expression of pancreatic lipase and colipase. AIM: To investigate the effects of long-term high-fat-feeding (113 days) on the mRNA expression of pancreatic lipase, colipase, pancreatic lipase-related proteins (1 and 2), and uncoupling proteins during the development of obesity and glucose in
Several studies have demonstrated the hybrid origin of Squalius alburnoides, a complex of diploid, triploid and tetraploid fish, with Squalius pyrenaicus as the maternal ancestor and an Anaecypris hispanica-like species as the paternal ancestor. The aim of this study was to assess patterns of genetic diversity and similarity between sympatric forms of the different ploidy levels of S. alburnoides
To develop novel methods for identifying new genes that contribute to the risk of developing type 1 diabetes within the Major Histocompatibility Complex (MHC) region on chromosome 6, independently of the known linkage disequilibrium (LD) between human leucocyte antigen (HLA)-DRB1, -DQA1, -DQB1 genes. We have developed a novel method that combines single nucleotide polymorphism (SNP) genotyping dat
This study describes differences in species richness, diversity and composition of Carabidae in gradients from recently abandoned, non-grazed fields over stages of overgrowth into forest on formerly agricultural land in a large, sandy outwash plain, south Sweden. Totally 80 pitfall traps, (4 succession stages, each represented by 4 sites; 5 traps per site) installed on 29 March 2006 were emptied c
Three-dimensional (3D) reconstructions of the two 8.4 MDa Rapana thomasiana hemocyanin isoforms, RtH1 and RtH2, have been obtained by cryoelectron microscopy of molecules embedded in vitreous ice and single particle image processing. The final 3D structures of the RtH1 and RtH2 didecamers at 19 angstrom and 16 angstrom resolution, respectively, are very similar to earlier reconstructions of gastro
Carvedilol, an antihypertensive drug with activity on adrenoceptors as well as on calcium channel activity, has recently been introduced. In the present study we investigated whether carvedilol interacts with the cytotoxicity induced by irradiation in vitro as well as in vivo. A daily injection of carvedilol in clinically relevant concentrations (3 mg/kg subcutaneously), 4 days before and 3 days a
To reduce the examination time for dark adaptometry, which including preadaptometry normally takes 30 minutes for an eye, a computerized adaptometer was constructed allowing monocular examination of both eyes simultaneously. The total examination time was thereby reduced from 60 to 30 minutes. This improvement was achieved by the use of electronically monitored transparent shutters that were alter
Tumour angiogenesis and the levels of plasminogen activator inhibitor type I (PAI-I) are both informative prognostic markers in breast cancer. In cell cultures and in animal model systems, PAI-I has a proangiogenic effect. To evaluate the interrelationship of angiogenesis and the PAI-I level in breast cancer, we have evaluated the prognostic value of those factors in a total of 228 patients with p
