In men with non-obstructive azoospermia (NOA), the risk of hypogonadism is often overlooked. Testicular sperm extraction (TESE) may increase this risk. The objective of this study was to elucidate the prevalence of hypogonadism in NOA-patients, the impact of TESE on hormone balance and the association between testosterone deficiency and dyslipidaemia. Men with NOA who had undergone TESE during the

OBJECTIVES: This study examined which individual and national factors affect condom use among adolescents. STUDY DESIGN: Multilevel analysis. METHODS: This study reviewed the data on bullying, alcohol use and condom use provided by 18 European countries and subnational entities in the Health Behaviour in School-Aged Children survey. Another eight contextual variables were also analysed. Three mult

The clinically important Kidd (JK) blood group system is considered to be relatively uncomplicated, both serologically and genetically. The JK*01 and JK*02 alleles give rise to Jk(a) and Jk(b) antigens, respectively, and silenced alleles result in Jk(a-b-). Other inherited variants analogous to Fy(x) and weak D phenotypes have not been characterized for JK, although recent abstracts indicate their

Iterative reconstruction (IR) algorithms improve image quality and allow for radiation dose reduction in CT. Dose reduction is particularly challenging in brain CT where good low-contrast resolution is essential. Ideally, evaluation of image quality combines objective measurements and subjective assessment of clinically relevant quality criteria. Subjective assessment is associated with various pi

Kulturartikel om RW Fassbinder med anledning av Thomas Elsaessers bok Fassbinder's Germany: History, Identity, Subject.

A multivariate statistical analysis of paper strength and production process data from the SCA Munksund paper mill is presented. The analysis is divided into five parts: (i) paper quality variables, (ii) process variables from the paper machine, (iii) process variables from digester and refiner, (iv) a combination of all process variables, and (v) a further analysis of the z-strength. Analysing

This article describes the Survivable Network Design Library (SNDlib), a data library for fixed telecommunication network design available at http://sndlib.zib.de. In the current version 1.0, the library contains data related to 22 networks which, combined with a set of selected planning parameters, leads to 830 network design problem instances. In this article, we discuss the data concepts of SND

A discussion on churches and centrality followed by an overview of medieval basilicas and hall churches in Scandinavia and Livonia.

Denna undersökning, som är finansierad av NUTEK, besvarar frågan om små och medelstora företag har några konkurrensfördelar av ett standardiserat miljöledningssystem (ISO 14001). Som utgångspunkt för undersökningen har en djupintervju med 30 ISO 14001-certifierade små och medelstora företag i södra Sverige använts. Dessa resultat har sedan jämförts med en enkätundersökning som skickats till övriga

The virion glycoproteins Gn and Gc of Bunyamwera orthobunyavirus (family Bunyaviridae) are encoded by the M RNA genome segment and have roles in both viral attachment and membrane fusion. To investigate further the structure and function of the Gc protein in viral replication, we generated 12 mutants that contain truncations from the N terminus. The effects of these deletions were analysed with re

CD46 is a cell surface complement inhibitor widely expressed in human tissues, in contrast to mice, where expression is limited to the testes. In humans, it has been identified as an important T cell costimulatory receptor, and patients deficient in CD46 or its endogenous ligands are unable to mount effective Th1 T cell responses. Stimulation of human CD4(+) T cells with CD3 and CD46 also leads to

BACKGROUND: To elucidate the mechanism by which local delivery of 3-morpholino-sydnonimine (SIN-1) affects intimal hyperplasia after percutaneous transluminal coronary angioplasty (PTCA). METHODS: Porcine coronary arteries were treated with PTCA and immediately afterwards locally treated for 5 minutes, with a selective cytosolic guanylate cyclase inhibitor, 1 H-(1,2,4)oxadiazole(4,3-alpha)quinox
