Previously Associated Type 2 Diabetes Variants May Interact With Physical Activity to Modify the Risk of Impaired Glucose Regulation and Type 2 Diabetes A Study of 16,003 Swedish Adults

OBJECTIVE-Recent advances in type 2 diabetes genetics have culminated in the discovery and confirmation of multiple risk variants. Two important, and largely unanswered questions are whether this information can be used to identify individuals most susceptible to the adverse consequences of sedentary behavior and to predict their response to lifestyle intervention; such evidence Would be mechanist

Impact of Oxygen Coadsorption on Intercalation of Cobalt under the h-BN Nanomesh.

The process of penetration of cobalt atoms through the h-BN nanomesh on Rh(111) is investigated with both spectroscopic and microscopic techniques. It is discovered that oxygen coadsorption can drastically modify the physical properties and behavior of the deposited Co clusters upon postannealing. In the absence of oxygen, Co forms small nanoparticles in the pores (bonding parts) of the h-BN nanom

Prompt photons in photoproduction at HERA

The production of prompt photons is measured in the photoproduction regime of electron-proton scattering at HERA. The analysis is based on a data sample corresponding to a total integrated luminosity of 340 pb(-1) collected by the H1 experiment. Cross sections are measured for photons with transverse momentum and pseudorapidity in the range 6< E-T(gamma) < 15 GeV and -1.0< eta(gamma) < 2.4, respec

Complement activation in thrombotic microangiopathy.

The endothelium lining the vascular lumen is continuously exposed to complement from the circulation. When erroneously activated on host cells, complement may generate a deleterious effect on the vascular wall leading to endothelial injury, exposure of the subendothelial matrix and platelet activation.In this review the contribution of complement activation to formation and maintenance of the path

Measurement Uncertainty, Channel Simulation, and Disturbance Characterization of an Over-the-Air Multi-Probe Setup for Cars at 5.9 GHz

Over-the-air multi-probe setups provide an efficient way to characterize the performance of today’s advanced wireless communication systems. In this paper the measurement uncertainty of such a setup using a car as a test object is characterized through three experiments: measurement system analysis, channel sounder measurements, and probe coupling measurements. Four issues were in focus for the an

Image Quality Optimisation and Dose Management in CT, SPECT/CT, and PET/CT

Popular Abstract in Swedish Det diagnostiska värdet av röntgen- och nuklearmedicinska undersökningar kan knappast över¬skattas. Däremot innebär undersökningar som baseras på joniserande strålning en liten risk för patienten att senare i livet utveckla en cancer. Därför är det vår skyldighet att hålla stråldoserna så låga som möjligt med bibehållen diagnostisk noggrannhet. Idag utgör medicinska undThe significant increase in the use of CT, alone or combined with SPECT or PET, has raised concerns about patient radiation exposure and the consequent increased risk of malignancy later in life. The overall objective of this work was to evaluate and optimise different approaches for minimising patient radiation absorbed dose and maintaining or improving image quality in CT, SPECT/CT, and PET/CT.

Signaling and regulation of cysteinyl leukotriene receptors in intestinal epithelial cells and colon cancer

Colorectal cancer is the third most common type of cancer, and the second leading cause of cancer-related deaths in the Western world. Chronic inflammation, such as inflammatory bowel diseases (IBD), increases the risk of cancer. Cysteinyl leukotrienes are pro-inflammatory mediators that are involved in IBD. They are ligands to the G-protein coupled receptors CysLT1R and CysLT2R, of which CysLT1R

Kinetic Studies of Amino Acid-Based Surfactant Binding to DNA

In this work, the binding kinetics of amino acid-based surfactants, presenting different linkers and head groups, with calf thymus (CT)-DNA was studied using stopped-flow fluorescence spectroscopy. The kinetic studies were carried out as a function of Na+ concentration and surfactant-to-DNA charge ratio. The surfactant binding on DNA took place in two consecutive steps, for which the corresponding

Suicide Risk in Men with Prostate-Specific Antigen-Detected Early Prostate Cancer: A Nationwide Population-Based Cohort Study from PCBaSe Sweden

Background: The risk of suicide is increased among cancer patients including men with prostate cancer (PCa). However, whether this increased risk applies to men diagnosed subsequent to prostate-specific antigen (PSA) testing is not known. Objective: To assess the risk of suicide among men diagnosed with PCa subsequent to PSA testing. Design, setting, and participants: The Prostate Cancer Base Swed

Role of ß-catenin and Leukotriene in Colon Cancer Progression

Abstract Colorectal cancer is the third most common cancer worldwide. Deregulation of Wnt/β-catenin signalling pathway is an early hallmark of colon cancer. Were nuclear accumulation of β-catenin is a marker of activated canonical Wnt/β-catenin signaling. One of the risk factors for development of colon cancer is inflammatory bowel disease. Inflammatory microenvironment is an essential component

Assistive Devices in Everyday Life for Very Old People - Use, Non-use and Opportunities for Use

The overarching aim of this thesis was to contribute to the existing knowledge on the use of assistive devices in everyday life, by adding the perspective of very old single living people in a European context, namely Latvia and Sweden. The aim was to investigate the socio-demographics and environmental and health aspects that impact on device use in the two national contexts. A further aim was to

Evaluation of the influence of CO2 on hydrogen production by Caldicellulosiruptor saccharolyticus

Stripping gas is generally used to improve hydrogen yields in fermentations. Since CO2 is relatively easy to separate from hydrogen it could be an interesting stripping gas. However, a higher partial CO2 pressure is accompanied with an increased CO2 uptake in the liquid, where it hydrolyses and induces an increased requirement of NaOH to maintain the pH. This enhances the osmotic pressure in the c

Nuclear modification factors of phi mesons in d plus Au, Cu plus Cu, and Au plus Au collisions at root s(NN)=200 GeV

The PHENIX experiment at the Relativistic Heavy Ion Collider has performed systematic measurements of phi meson production in the K+K- decay channel at midrapidity in p + p, d + Au, Cu + Cu, and Au + Au collisions at root s(NN) = 200 GeV. Results are presented on the phi invariant yield and the nuclear modification factor R-AA for Au + Au and Cu + Cu, and R-dA for d + Au collisions, studied as a f

Cryogel applications in microbiology.

There is a great demand for improved technologies with regard to rapid processing of nano- and microparticles. The handling of viruses in addition to microbial and mammalian cells requires the availability of appropriate adsorbents. Recent developments in macroporous gels produced at subzero temperatures (known as cryogels) have demonstrated an efficiency for processing cell and virus suspensions,

Do Reproductive Factors Influence T, N, and M Classes of Ductal and Lobular Breast Cancers? A Nation-Wide Follow-Up Study

Backgrounds: The clinical tumor-node-metastasis (T, N and M) classes of breast cancers provide important prognostic information. However, the possible association of TNM classes with reproductive factors has remained largely unexplored. Because every woman has a reproductive history, implications to outcome prediction are potentially significant. Methods: During the study period from 2002 through
