Genetic and Environmental Risk Factors in the Development of Obesity

Lifestyle behaviors and genetic variation have clear and distinguishable effects on obesity risk; however, the pattern of disease occurrence within and between populations that differ in their genetic and environmental underpinnings suggests obesity is caused in part by the interaction between adverse lifestyle behaviors and the genetic risk profile of an individual. This thesis aims to investigat

Sense of coherence among cognitively intact nursing home residents - a five-year longitudinal study

Aim and objectives: To examine how stable the sense of coherence (SOC) is over a five-year period among residents of nursing homes (NH) who are not cognitively impaired and whether components of social support influence SOC. Background: Many studies have investigated the stability of SOC, and the findings have been inconsistent. Social support is a crucial resource in developing SOC. Few researche

Dietary glycemic index and glycemic load and breast cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Background: The glycemic potential of a diet is associated with chronically elevated insulin concentrations, which may augment breast cancer (BC) risk by stimulating insulin receptor or by affecting insulin-like growth factor I (IGF-I)-mediated mitogenesis. It is unclear whether this effect differs by BC phenotype. Objective: The objective was to investigate the relation between glycemic index (GI

Methods for determination of duration of surface moisture and presence of water in gaps in wood joints

If water stays on wood surfaces or is trapped in gaps, the wood is supplied with water for a long period of time and high local moisture contents are reached. This can lead to decay by rot fungi, and it is therefore important to avoid such water traps in order to limit the decay rate. This paper presents two methods: one for determination of duration of surface moisture on wood surfaces and one fo

Galectin-3 Targeted Therapy with a Small Molecule Inhibitor Activates Apoptosis and Enhances Both Chemosensitivity and Radiosensitivity in Papillary Thyroid Cancer

Although most patients with papillary thyroid cancer (PTC) have favorable outcomes, some have advanced PTC that is refractory to external beam radiation and systemic chemotherapy. Galectin-3 (Gal-3) is a beta-galactoside-binding protein with antiapoptotic activity that is consistently overexpressed in PTC. The purpose of this study is to determine if Gal-3 inhibition promotes apoptosis, chemosensi

Aspects of bleeding complications and hemostasis at central line insertion and mild induced hypothermia

Popular Abstract in Swedish Blodlevring är en samlingsterm för en serie reaktioner som medför att blod omvandlas från vätska till en geléliknande massa. I koagulationsprocessen samverkar de minsta cellerna i blodet, trombocyterna (blodplättarna), med ett stort antal blodproteiner. Koagulationens viktigaste uppgift är att stoppa blödningar som uppkommer vid skador på blodkärlen. Central venkateteBleeding complications range from 0.5 to 1.6% in connection with central venous catheter insertions but are more frequent in patients with bone marrow failure and severe thrombocytopenia. Although supportive evidence is scarce, prophylactic platelet transfusion is sometimes performed in these patients before catheter insertion. Furthermore, the ideal threshold platelet count and timing of transfus

Energy-Efficient Decentralized Cooperative Routing in Wireless Networks

Wireless adhoc networks transmit information from a source to a destination via multiple hops in order to save energy and, thus, increase the lifetime of battery-operated nodes. The energy savings can be especially significant in cooperative transmission schemes, where several nodes cooperate during one hop to forward the information to the next node along a route to the destination. Finding the b

The Merit of Meritocratization: Politics, Bureaucracy, and the Institutional Deterrents of Corruption

Comparative studies of corruption focus on the selection and incentives of policymakers. With few exceptions, actors who are in charge of implementing policies have been neglected. This article analyzes an original data set on the bureaucratic features and its effects on corruption in fifty-two countries. Two empirical findings challenge the conventional wisdom in literature. First, certain bureau

Interaction between two spheres placed in tandem arrangement in steady and pulsating flow

The interaction among two spheres in tandem formation are studied for a Reynolds number of 300 using both steady and pulsating inflow conditions. The purpose is to further investigate the force characteristics as well as the shedding patterns of the two spheres as the separation distance is changed from 1.5 to 12. sphere diameters. The method used for the simulations is the volume of solid (VOS) m

Highlights from PHENIX I

This contribution highlights recent results from the PHENIX Collaboration at RHIC. It covers global variables, flow and 2-particle correlations. A second contribution in this issue, by T C Awes (2008 J. Phys. G: Nucl. Part. Phys. 35 104007), covers PHENIX results on heavy quarks, leptons and photons.

The effect of elevated pressures on the laminar burning velocity of methane plus air mixtures

In spite of the large amount of research spent on the evaluation of the high pressure dependence of laminar burning velocity of methane + air flame, there still exists a large uncertainty in the data for various reasons. In order to reduce the scatter to acceptable levels, the Heat Flux Method (HFM), known as a potential method with high accuracy, has been extended to higher pressures. New measure
