CONTEXT The cause of declining testosterone (T) in aging men and their relationships with risk factors are unclear. OBJECTIVE To investigate the relationships between lifestyle and health with reproductive hormones in aging men. DESIGN Baseline cross-sectional survey on 3200 community - dwelling men aged 40 - 79 yr from a prospective cohort study in 8 European countries. RESULTS Four predictors we

How are social movements of the underdogs sustained and how are constraints of these movements overcome, in particular, constraints imposed by non-liberal democratic states? Utilizing the Damansara Save Our School movement in Malaysia as its case study, this article describes factors that led to the successful resistance of the Damansara New Village community against the closure of its community s

The concept, design and prototype developments for the Lund-York-Cologne CAlorimeter (LYCCA) is presented. LYCCA is a modular device for the NUclear STructure, Astrophysics and Reactions (NUSTAR) science pillar of the Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany. LYCCA is designed to discriminate heavy ions produced in nuclear reactions induced by relativistic radioactive

The evolution of the nuclear shell structure in the region of the neutron-rich shell-breaking nucleus Mg-32 has been the subject of considerable interest. We present here the first determination of the overlap of the ground and two first excited states in Mg-31 with a neutron coupled to the ground state in Mg-30 based on studies of its isobaric analog resonances in Al-31. The excitation function f

Conventional surveillance systems are omnipresent and most are still based on analog techniques. Migrating to the digital domain grants access to the world of digital image processing enabling automation of such systems, which means extracting information from the image stream without human interaction. The resolution, frame rates, and functionality in these systems are continuously increasing alo

Disperse dyes are the most common allergens among textile dyes. It is not known whether the purified dyes, impurities in the commercial dyes, or metabolites are the actual sensitisers. Moreover, it is not known whether those disperse dyes that are now present in test series are actually used in textile dyeing today. The aim of this thesis was A) to evaluate the significance of the impurities foun

Particle number size distributions at various field sites are used to identify atmospheric new-particle formation (NPF) event days. However, the spatial distribution of regionally extensive events is unknown. To remedy this situation, the NanoMap method has been developed to enable the estimation of where NPF occurs within 500 km from any field station using as input size distribution and meteorol

Popular Abstract in Swedish Arsenik (As) finns i grundvatten på många platser i världen, och mer än 100 miljoner människor världen över exponeras dagligen för As via dricksvatten. Kronisk exponering för As kan orsaka bl.a. cancer, hjärt-kärlsjukdom och diabetes. När As omsätts (metaboliseras) i kroppen bildas flera olika omsättningsprodukter (metaboliter) emellan vilka giftigheten skiljer sig åt. Over 100 million people around the world are exposed to high concentrations of arsenic (As) in drinking water, associated with a number of adverse health effects such as skin, lung and bladder cancer, vascular diseases and diabetes. In humans, As is metabolized via alternating reduction and methylation reactions, from inorganic As (iAs) into monomethylated (MMA) and dimethylated As (DMA). The most

Recombinant adenovirus serotype 5 (Ad5) vectors represent one of the most efficient gene delivery vectors in life sciences. However, Ad5 is dependent on expression of the coxsackievirus-adenovirus- receptor (CAR) on the surface of target cell for efficient transduction, which limits it's utility for certain cell types. Herein we present a new vector, Ad5PTDf35, which is an Ad5 vector having seroty

Purpose The XPC gene is involved in DNA damage recognition in the nucleotide excision repair pathway (NER) We investigated the additive effects of single nucleotide polymorphisms (SNPs) in bladder-cancer patients and population controls for three XPC polymorphisms A499V (C>T) K939Q (A>C) and poly AT (PAT -/+) Experimental Design 311 bladder-cancer patients from a population-based cohort and 337 po

Aims. We study how diffuse interstellar bands (DIBs) measured toward distance-distributed target stars can be used to locate dense interstellar (IS) clouds in the Galaxy and probe a line-of-sight (LOS) kinematical structure, a potentially useful tool when gaseous absorption lines are saturated or not available in the spectral range. Cool target stars are numerous enough for this purpose. Methods.

The social surroundings in which an individual grows up and spends his or her everyday life have an effect on his or her life chances. Much of the research into this phenomenon focuses on so-called neighborhood effects and has put particular emphasis on the negative effects of growing up in a poor neighborhood. Originating from the sociological study of inner-city problems in the United States, th

Polysulfones functionalized with highly phosphonated poly(pentafluorostyrene) side chains of different length were synthesized applying controlled polymerization and modification methods. The graft copolymers' thermal properties were evaluated by differential scanning calorimetry and thermal gravimetrical analyses. The proton conductivity of membrane prepared from the graft copolymer with the shor

Cyperus fuscus was thought to be extinct in Sweden until it was rediscovered at Lake Vombsjön, Skåne, after 63 years in 2013. The species also occurred at the lake 2014—2021, but in very variable numbers. The variation depended largely on the water level during late summer. Favourable conditions in form of low levels in late summer have also occurred prior to 2013, though less frequently than in rCyperus fuscus was rediscovered at Lake Vombsjön in Skåne, southernmost Sweden, in 2013. The species occurred there between 1945 and 1950, which was the latest Swedish record except for a casual occurrence in a plant nursery. The comeback was spectacular with 2770 individuals counted along 4.7 km of the shore. In 2013, the water level was exceptionally low for technical reasons, with up to 100 m o

• Premise of the study: Small, autogamous flowers have evolved repeatedly in the plant kingdom. While much attention has focused on the mechanisms that promote the shift to autogamy, there is still a paucity of information on the factors that underlie the reduction of flower size so prevalent in selfing lineages. In this study of Crepis tectorum, I examine the role of inbreeding, acting alone or t
