Background: In previous meta-analyses, tea consumption has been associated with lower incidence of type 2 diabetes. It is unclear, however, if tea is associated inversely over the entire range of intake. Therefore, we investigated the association between tea consumption and incidence of type 2 diabetes in a European population. Methodology/Principal Findings: The EPIC-InterAct case-cohort study wa
Traditionally, diagnosis of male infertility has relied upon microscopic assessment of semen. The normality criteria set by the World Health Organization (WHO) in regard to sperm concentration, motility and morphology are, however, poor predictors of fertility. In about half of the involuntarily childless couples the causes are solely or partly male related. In 60-75% of cases the aetiology of red
The eminent dilemma around the relationship between the increasing world population, the need of new fuel sources and environment issues has raised great awareness in the last decades. The European Parliament has set common goals such as the reduction of the greenhouse gases by 20 % by the year of 2020, followed by the requirement of at least 10 % of the fuel has to be biofuel. An adjacent issue i
Background: Animal studies suggest that the arginine vasopressin (AVP) system plays a role in glucose and fat metabolism, but data from humans are limited. Method and results: We analysed plasma copeptin (copeptin), a stable C-terminal fragment of the AVP pro-hormone in the large, Swedish, population-based cohort Malmö Diet and Cancer Study Cardiovascular Cohort (MDC-CC, n=6103). Using baseline
Popular science summary: Healing: what we can learn from white mice Stem cells are a cell type responsible for building the body. They are the ancestor cells from which all the cells making up the body’s tissues are created. Stem cells play an important role in maintaining the body in shape by repairing damages as they occur during life. We believe that if we had a better understanding of how t
Abstract Toxic cyanobacterial blooms can form in both freshwater and marine environments, which could threaten the health of human beings and animals. The genera that are known for causing the scums in freshwater are Anabaena, Microcystis, Cylindrospermopsis and Planktothrix. In order to control lake water quality and minimize the potential health risk associated with the cyanobacterial blooms, th
In Sweden, the tramway was introduced in the late 19th century as horse tramways. Entrepreneurs around the country saw advantages of the new mean of transport which, due to low frictional resistance could transport a large amount of passengers with low traction force. In the beginning of the 20th century the horses were replaced by electric motors and the tramway spread to more cities. The entry o
The alternating between dry and wet seasons and the consecutive microbial responses to soil water content in semiarid ecosystems has significant consequences on nitrogen exchanges with the atmosphere. Three field campaigns were carried out in a semi arid sahelian rangeland in Dahra (Ferlo, Senegal), two at the beginning of the wet season in July 2012 and July 2013, and the third one in November 20
Recent droughts from 2017 to 2020 induced significant stress on woodland canopies across eastern Australia, resulting in widespread tree browning and mortality. However, the trajectory of post-drought recovery remains unclear, with uncertainty about whether canopy conditions are improving or continuing to decline. Identifying the key local environmental and climatic factors influencing drought-ind
BACKGROUND: Defensive coping (DefS) was associated with a vulnerable cardiovascular profile in Blacks. The copeptin/vasopressin system is a manifestation of hypothalamic-pituitary-adrenal-axis activity and may act as an acute compensatory mechanism when there is a disruption in volume-loading homeostasis, i.e. when cardiac stress is evident. Whether DefS will influence associations between copepti
Silk fibers offer untapped internal structures to template the formation of nano-objects and active coatings. So far, access to all or part of the internal and organized structures has been a significant challenge. The aim of the thesis is, therefore, to identify and exploit silk templating ability to create value-added multifunctional hybrid materials with enhanced conductive and catalytic proper
Abstract. This study presents a comprehensive assessment of the meteorological conditions and atmospheric flow during the Lagrangian-type "Hill Cap Cloud Thuringia 2010" experiment (HCCT-2010), which was performed in September and October 2010 at Mt. Schmücke in the Thuringian Forest, Germany and which used observations at three measurement sites (upwind, in-cloud, and downwind) to study physical
Zn-Sb compounds (e.g., ZnSb, β-Zn13Sb10) are known to have intriguing thermoelectric properties, but studies of the Zn3Sb2 composition are largely absent. In this work, α-Zn3Sb2 was synthesized and studied via temperature-dependent synchrotron powder diffraction. The α-Zn3Sb2 phase undergoes a phase transformation to the β form at 425 °C, which is stable until melting at 590 °C. Rapid quenching wa
Popular Abstract in Swedish Syn är avgörande för många djurs överlevnad. En väldigt viktig del av ögat är linsen då ljuset fokuseras genom den. I denna studie har jag undersökt hur fisklinser fokuserar ljus. Valet av fiskar som försöksdjur berodde på att de är lätta att skaffa och deras linser är klotformade, vilket underlättar beräkningen av strålgången och linsens optiska egenskaper. Hos fiskar Vision is an important source of information for many animals. The lens plays a central role in the visual pathway and hence the ecology of these animals. Fish have spherically shaped crystalline lenses that contain a gradient of refractive index. Like all refracting elements, lens performance depends on the wavelength of the refracted light. This wavelength dependent focusing leads to chromatic a
Background: Vascular-targeted photodynamic therapy, a novel tissue-preserving treatment for low-risk prostate cancer, has shown favourable safety and efficacy results in single-arm phase 1 and 2 studies. We compared this treatment with the standard of care, active surveillance, in men with low-risk prostate cancer in a phase 3 trial. Methods: This randomised controlled trial was done in 47 Europea
It is increasingly acknowledged that climate change is influencing terrestrial ecosystems by increased drought and rainfall intensities. Soil microbes are key drivers of many processes in terrestrial systems and rely on water in soil pores to fulfill their life cycles and functions. However, little is known on how drought and rainfall fluctuations, which affect the composition and structure of mic
BACKGROUND: Blood group phenotype variation has been attributed to potential resistance to pathogen invasion. Variation was mapped in blood donors from Lampang (northern region) and Saraburi (central region), Thailand, where malaria is endemic. The previously unknown blood group allele profiles were characterized and the data were correlated with phenotypes. The high incidence of the Vel-negative
