Increased male age has been associated with significant reduction in pregnancy rates. This study investigated the association between age, the function of epididymal and accessory sex glands, and their relation to sperm motility. Ejaculates from 498 men assessed for infertility were analysed according to WHO [1999] guidelines. Seminal markers of epididymal (neutral alpha-glucosidase (NAG)), prosta

Amphiphilic polymers consisting of copolymethacrylates carrying about 26 wt % ethylene oxide [(EO)(n)] side chains of different lengths were used as matrices in gel electrolytes. The gel electrolytes were composed of 30 wt % copolymer and 70 wt % 1 M LiPF6 in a mixture of ethylene carbonate and gamma -butyrolactone (2/1 w/w). The coordination of lithium ions by the (EO)(n) side chains in competiti

The structure and organisation of the extracellular matrix, and in particular the axial alignment of type I collagen fibrils, are essential for the tensile strength of tendons. The resident tenocytes synthesize and maintain the composition of the extracellular matrix, which changes with age and maturation. Other components of the extracellular matrix include less abundant collagen types II, III, V

We have observed photons in the visible light range emitted from slow (2.0 keV/amu) highly charged Ar6+ ions which have captured one electron and transmitted through a Ni microcapillary target. Observed lines were identified by comparing with an ab initio calculation based on the multi-configuration Hartree-Fock method. (C) 2003 Elsevier Science B.V. All rights reserved.

Popular Abstract in Swedish I Sverige inträffar varje år c:a 1 500 självmord och minst 15 000 självmordsförsök. Självmordsbeteende är således ett problem som berör många människor i vårt samhälle. En grupp som löper en klart förhöjd risk att begå självmord är de personer som gjort självmordsförsök. "Självmordsförsökare" utgör dock en heterogen grupp av människor av olika ålder, kön, sociala omstänBetter understanding of suicidality may improve treatment and care of suicide attempters. This thesis aims at understanding suicidality by investigating suicide risk, sex differences and views of suicide attempters. Suicide risk factors (prospectively determined) differed between the sexes: Older age and high suicidal intent were female risk factors, whereas previous attempts and using a violent

OBJECTIVE - To describe the age- and sex-specific mortality in a cohort of young type 1 diabetic patients and to analyze the causes of death with special focus on suicide, accidents, and unexplained deaths. RESEARCH DESIGN AND METHODS - A population-based incident childhood diabetes register, covering onset cases since 1 July 1977, was linked to the Swedish Cause of Death Register up to 31 Decembe

We recorded and reviewed densities and basal areas of large living and dead trees in old-growth forest in Europe. Recorded densities were similar to those reported from old-growth forests in eastern North America, but lower than in northwestem North America. Based on our results we suggest that, 10-20 living trees per ha with dbh > 70 cm may have been typical values for many central European and s

Models of moisture flow processes in wood are normally based on a Fickian approach. In many instances, there are considerable discrepancies between modelling and experimental results. It is shown in this thesis that a major cause for these discrepancies is a so-called retarded sorption which is not accounted for in conventional theories. This retarded sorption occurs in the wood cell wall. A spec

The crucial role of platelets in maintaining primary hemostais has been evident for a long time and there is now also mounting evidence for their involvement in inflammation. In combination with aspirin, inhibition of the platelet P2Y12 ADP receptor with clopidogrel has become a cornerstone in the antiplatelet in acute coronary syndromes. Recently, several studies have indicated that a considerabl

Based on detailed 2D and 3D numerical radiation-hydrodynamics (RHD)simulations of time-dependent compressible convection, we have studiedthe dynamics and thermal structure of the convective surface layers of aprototypical late-type M-dwarf (T_effapprox 2800 K, log g=5.0,solar chemical composition). The RHD models predict stellar granulationqualitatively similar to the familiar solar patt

Motivationen har stor betydelse för att rehabilitering ska ge ett gott resultat, det har studerats och förts till bevis i andra studier. Den första långtidsuppföljningen av motivationens betydelse ur ett hälsoekonomiskt perspektiv vid rehabilitering har genomförts i Kronobergs län.

Obesity is associated with increased triacylglycerol (TAG) storage in adipose tissue and insulin resistance. The mobilization of stored TAG is mediated by hormone-sensitive lipase (HSL) and the recently discovered adipose triglyceride lipase (ATGL). The aim of the present study was to examine whether ATGL and HSL mRNA and protein expression are altered in insulin-resistant conditions. In addition,
