An introduction to the South Swedish Apparent Cleft (SSAC)

Abstract: In this paper, the South Swedish Apparent Cleft (SSAC) is introduced, described and briefly discussed. The SSAC was first observed in the 1940s, and it has not yet been subject to any detailed linguistic analysis. The usage of the SSAC has been examined in a corpus study and via a questionnaire, and the results suggest (albeit inconclusively) that it truly is a specifically south Swedish

Arabidopsis PDK1: identification of sites important for activity and downstream phosphorylation of S6 kinase

The A rabidopsis thaliana protein kinase AtPDK1 was identified as a homologue of the mammalian 3-phosphoinositide-dependent protein kinase-1 (PDK1), which is involved in a number of physiological processes including cell growth and proliferation. We now show that AtPDK1 expressed in E. coli as a recombinant protein, undergoes autophosphorylation at several sites. Using mass spectrometry, three pho

Polymorphisms in the gene encoding the voltage-dependent Ca(2+) channel Ca (V)2.3 (CACNA1E) are associated with type 2 diabetes and impaired insulin secretion

AIMS/HYPOTHESIS: Glucose-stimulated insulin secretion is dependent on the electrical activity of beta cells; hence, genes encoding beta cell ion channels are potential candidate genes for type 2 diabetes. The gene encoding the voltage-dependent Ca(2+) channel Ca(V)2.3 (CACNA1E), telomeric to a region that has shown suggestive linkage to type 2 diabetes (1q21-q25), has been ascribed a role for seco

Exact treatment of classical trajectories governed by an isotropic potential for linewidth computations

Two models for exact classical trajectories in the field of an isotropic potential are investigated for the purpose of semiclassical linebroadening calculations. The first directly uses the exact solution of the classical equation of motion. The second starts from the equation of motion and computes the trajectory by numerical solution of the differential equations. In the framework of both models

Practical HDR texture compression

The use of high dynamic range (HDR) textures in real-time graphics applications can increase realism and provide a more vivid experience. However, the increased bandwidth and storage requirements for uncompressed HDR data can become a major bottleneck. Hence, several recent algorithms for HDR texture compression have been proposed. In this paper, we discuss several practical issues one has to co

Forced expression of the cyclin-dependent kinase inhibitor p16(INK4A) in leukemic U-937 cells reveals dissociation between cell cycle and differentiation

OBJECTIVE: The aim of this study was to investigate how the tumor suppressor protein p16(INK4A) interferes with growth and differentiation of leukemic U-937 cells. MATERIALS AND METHODS: U-937 clones constantly overexpressing the cyclin-dependent kinase inhibitor p16(INK4A) were established. Clones transfected with empty vector were used as controls. The effects of high-level expression of p16(INK

Comprehensive mutational analysis of a cohort of Swedish Cornelia de Lange syndrome patients

Cornelia de Lange syndrome (CdLS; OMIM 122470) is a rare multiple congenital anomaly/mental retardation syndrome characterized by distinctive dysmorphic facial features, severe growth and developmental delay and abnormalities of the upper limbs. About 50% of CdLS patients have been found to have heterozygous mutations in the NIPBL gene and a few cases were recently found to be caused by mutations

North versus South: Energy transition and energy intensity in Europe over 200 years

The paper examines energy consumption in Sweden, Holland, Italy and Spain over 200 years, including both traditional and modern energy car-riers. The article is based on totally new series of energy consumption in-cluding traditional carriers along with modern sources. Our main purposes are a closer examination of the process of the energy transition in Europe and a revision of the prevailing idea

Stimulation of vascular protein synthesis by activation of oestrogen receptor beta

The objective of this study was to investigate the effects of oestrogen receptor (ER) beta activation on vascular protein synthesis and protein expression. Nuclear immunoreactivity towards ER beta was observed abundantly in vascular smooth muscle and endothelial cells of mouse aorta. No ER alpha-positive cell nuclei were observed. In aorta from ovariectomized mice, treatment with the selective ER

Can DXA Predict Fractures in Renal Transplant Patients?

Renal transplant patients have a high prevalence of osteopenia, osteoporosis and fractures. The aim of the study was to investigate whether dual-energy x-ray absorptiometry (DXA) is of value to predict fractures. In 1995-2007, 238 renal transplant patients underwent 670 DXA investigations. Osteopenia (46.0%), osteoporosis (13.9%) and absolute bone mineral density (BMD) (median 0.9, range 0.4-2.0 g

Evidence that vildagliptin attenuates deterioration of glycaemic control during 2-year treatment of patients with type 2 diabetes and mild hyperglycaemia

Aim: To assess the 2-year efficacy and tolerability of vildagliptin (50 mg once daily) in patients with type 2 diabetes (T2DM) and mild hyperglycaemia. Methods: This was a multicentre, randomized, double-blind, placebo-controlled trial comprising a 52-week core study with a 4-week, active treatment-free washout followed by a 52-week extension study with another washout period conducted in 131 drug

Oxytocin and oxytocin-receptor mRNA expression in the human gastrointestinal tract: a polymerase chain reaction study

Background/aim: Oxytocin (OT) has a wide range of effects throughout the body. However, the role of OT on the gastrointestinal (GI) tract has to be settled. So far, the few studies performed reveal no conclusive results. The aim of this study was to examine the expression of Of and OT-receptor mRNA in the human GI tract. Material and methods: Full-thickness biopsies from all segments of the GI tra

Concentration of BNP, endothelin 1, pro-inflammatory cytokines (TNF-alpha, IL-6) and exercise capacity in patients with heart failure treated with carvedilol

Background: Recent studies on the pathophysiology of heart failure indicate the role of neurohormones and immune and inflammatory processes as potential mechanisms involved in the pathogenesis and clinical course of chronic heart failure (CHF). Aim: To analyse the relationship between concentrations of brain natriuretic peptide (BNP), endothelin-1 (ET-1), inflammatory cytokines (TNF-alpha, IL-6) a

Isolation, characterization and multiplex polymerase chain reaction of novel microsatellite loci for the avian parasite Philornis downsi (Diptera: Muscidae)

An enrichment technique was used to isolate 11 di-, tri-, and tetra microsatellites for the parasitic fly Philornis downsi (Diptera: Muscidae). These loci were polymerase chain reaction amplified in singleplexes or two-plexes for P. downsi. The loci showed low to moderate polymorphism, exhibited between three and four alleles, and observed heterozygosity ranged from 0.05 to 0.86. These new markers

Comparison of DEM Data Capture and Topographic Wetness Indices

Digital elevation models (DEMs) can be captured and analysed by various methods. Elevation capturing with RTK-GPS and airborne laser scanning is presented and evaluated in terms of height accuracy of raw data and interpolated DEMs for study sites in Sweden and Germany. Applications for precision agriculture are based on the connection of land surface and the movement of water in the landscape. Thr

Differential expression of myrosinase gene families

In mature seeds of Brassica napus three major and three minor myrosinase isoenzymes were identified earlier. These myrosinases are known to be encoded by at least two different families of myrosinase genes, denoted MA and MB. In the work described in this paper the presence of different myrosinase isoenzymes in embryos, seedlings, and vegetative mature tissues of B. napus was studied and related t

Maternal Epstein-Barr virus and cytomegalovirus infections and risk of testicular cancer in the offspring: a nested case-control study

During recent decades the incidence of testicular cancer (TC) has increased rapidly around the world. Associated exogenous etiological factors might therefore be identifiable. We performed a case-control study nested within Finnish, Swedish and Icelandic maternity cohorts exploiting early pregnancy serum samples to evaluate the role of congenital or neonatal infections with Epstein-Barr virus (EBV
