Context:Late-onset hypogonadism (LOH) has been defined as a syndrome in middle-aged and elderly men reporting symptoms in the presence of low testosterone (T). Objective:The objective of the study was to seek objective biochemical and end-organ evidence of androgen deficiency in men classified as having LOH according to our previously published criteria. Design, Setting, and Participants:The des

In the female turnip moth, Agrotis segetum, a pheromone biosynthesis activating neuropeptide (PBAN) stimulates sex pheromone biosynthesis which exhibits a daily rhythm. Here we show data supporting a circadian rhythm in PBAN release from the corpora cardiaca, which we propose regulates the endogenous rhythm in sex pheromone biosynthesis. This conclusion is drawn as the observed daily rhythm in PBA

Fanconi anemia is a recessively inherited disease that is characterized by congenital abnormalities, bone marrow failure, and a predisposition to develop cancer, particularly squamous cell carcinomas (SCCs) in the head and neck and anogenital regions. Previous studies of Fanconi anemia SCCs, mainly from US patients, revealed the presence of high-risk human papillomavirus (HPV) DNA in 21 (84%) of 2

Popular Abstract in Swedish Bomärken har använts som ägarbeteckning och signatur i Norden in på 1800-talet, och i vissa reliktområden intill nutid. Bomärkena återfinns t.ex. i mantalslängder, jordaböcker och bouppteckningar, men även inskurna på äldre redskap, husgeråd och annat lösöre. Bomärkena har av somliga forskare ansetts ha utformats slumpvis, enbart med syftet att kunna skilja en bomärkesThe pioneering academic research on Merchant Marks (also known as identity marks, personal marks, ownership marks, identification marks, Hausmarken, Hofmarken, Marques de Propriété, bomärken) was done by professor Homeyer (1870). Since 1870 there has been an ongoing debate among scholars whether Merchant Marks are simply formed by chance and coincidence, as stated by Rehnberg (1938, 1951), Scheffe

Popular Abstract in Swedish Denna studie betonar att de mekanismer, som skapar tillväxt, inte nödvändigtvis är universella utan kan skilja sig åt mellan olika områden, beroende på vad som produceras och vilken teknik som används. Avhandlingen hävdar inledningsvis att ekonomisk tillväxt är den viktigaste enskilda faktor som påverkar individers inkomstnivå och att ökad produktivitet i sin tur är gruThis study shows that the mechanisms behind knowledge accumulation and the sources of productivity growth differ from industry to industry depending on what is produced and what technology is used. Although it is apparent to most researchers in the field that the only way to explain long-run growth in output per capita is through technological progress and accumulation of knowledge that counteract

The mucosal lymphocyte integrin alpha E(CD103)beta 7 is thought to be important for intraepithelial lymphocyte (IEL) localization or function. We cloned the murine integrin gene encoding alpha E, localized it to chromosome 11, and generated integrin alpha E-deficient mice. In alpha E-/- mice, intestinal and vaginal IEL numbers were reduced, consistent with the known binding of alpha E beta 7 to E-

The ion photon emission microscope, or IPEM, is the first device that allows scientists to microscopically study the effects of single ions in air on semiconductors, microchips and even biological cells without having to focus the beam. Reported here is a prototype, the size of a conventional optical microscope, developed at Sandia. The alpha-IPEM, that employs alpha particles from a radioactive s

In vivo gene transfer using viral vectors is an emerging therapy for neurodegenerative diseases with a clinical impact recently demonstrated in Parkinson's disease patients. Recombinant adeno-associated viral (rAAV) vectors, in particular, provide an excellent tool for long-term expression of therapeutic genes in the brain. Here we used the [C-11] raclopride [(S)-(-)-3,5-dichloro-N-((1-ethyl-2-pyr

Several stilbenoid compounds having structural similarity to the combretastatin group of natural products and characterized by the incorporation of two nitrogen-bearing groups (amine, nitro, serinamide) have been prepared by chemical synthesis and evaluated in terms of biochemical and biological activity. The 2',3'-diamino B-ring analogue 17 demonstrated remarkable cytotoxicity against selected hu

We present deep Hubble Space Telescope ACS observations of the G1 clump, a distinct stellar overdensity lying at similar to 30 kpc along the southwestern major axis of M31, close to the G1 globular cluster ( from the work of Ferguson and coworkers). Our well-populated color-magnitude diagram reaches similar to 7 mag below the red giant branch tip with 90% completeness, and allows the detection of

Popular Abstract in Swedish Vad är egentligen kristen etik? Hur lär människor sig vad som är rätt och fel? Varför förändras normer och värderingar? Sådana stora och viktiga frågor får en konkret belysning i denna avhandling som undersöker normer och värderingar i svensk frikyrklighet. Lite ironiskt sa man förr att frikyrkliga hade en "syndakatalog": de fick exempelvis inte snusa, dansa eller ha sThe dissertation describes and characterises ethical reflection in the Swedish Free Churches during the period from the 1930s to the 1990s. It is built primarily on two sources of material. The first one is a summary of discussions and statements on marriage, divorce and remarriage from books, journals and papers, mainly from two denominations: the Swedish Covenant Church and the Örebromission. Th

The electronic structure of GaAs (100) grown by low-temperature molecular beam epitaxy was investigated by means of photoemission spectroscopy. Slight differences are found in the valence band spectra of GaAs layers grown at different As-2/Ga flux ratios. Analysis of As 3d core level spectra does not indicate qualitative differences in respect to high temperature grown GaAs (100) layers. The Ga 3d

This study of stress-related antinuclear antibody (ANA) reactivity was undertaken with the objective of improving clinical ANA testing. ANA was determined by parallel enzyme-linked immunosorbent assays of crude nuclear protein antigen extracted from HEp-2 cells either grown under optimal conditions (providing nonstress ANA antigen) or exposed to stress (providing stress ANA antigen). The stress st

Popular Abstract in Swedish Studien behandlar bibelbruket i den grekiska systematiska samlingen av Apophthegmata Patrum ( kenfädernas tänkespråk). Efter en inledande genomgång av tidigare forskning på biblebruk i allmänhet och det i tänkespråken i synnerhet formuleras undersökningens syfte så: att beskriva hur bibeltexten kontextualiseras, dvs. hur texten infogas i den undervisning och de ideal soThis study is devoted to the use of the Bible in the Greek systematic collection of Apophthegmata Patrum (AP). After an introductory survey of earlier research on the use of Scripture in general, and that of AP in particular, the main purpose of the investigation is formulated: to describe how the Bible text is contextualized, i.e., how the text is integrated with the teachings and ideals in the s

The emission spectra of lithium orthosilicates (Li4SiO4) ceramics have been measured in the range of 1.8-5.8 eV under irradiation by 6-30 eV photons or 1-30 keV electrons at 6-300 K. The tunnel recombination phosphorescence, as well as luminescence, stimulated by 1.5-2.5 eV photons has been detected in the sample preliminarily irradiated at 6 or 80 K. The main peaks of thermally stimulated lumines

Plasmacytoid dendritic cells (pDCs) efficiently produce large amounts of type I IFN in response to TLR7 and TLR9 ligands, whereas conventional DCs (cDCs) predominantly secrete high levels of the cytokines IL-10 and IL-12. The molecular basis underlying this distinct phenotype is not well understood. In this study, we identified the MAPK phosphatase Dusp9/MKP-4 by transcriptome analysis as selectiv

The existence of a vertical age gradient in the Milky Way disc has been indirectly known for long. Here, we measure it directly for the first time with seismic ages, using red giants observed by Kepler. We use Stromgren photometry to gauge the selection function of asteroseismic targets, and derive colour and magnitude limits where giants with measured oscillations are representative of the underl

The oomycete Phytophthora infestans is the causal agent of late blight in potato and tomato. Since the underlying processes that govern pathogenicity and development in P. infestans are largely unknown, we have performed a large-scale phosphoproteomics study of six different P. infestans life stages. We have obtained quantitative data for 2922 phosphopeptides and compared their abundance. Life-sta
