Sexuality of 15/16-Year-Old Girls and Boys With and Without Modest Disabilities

Girls and boys with disabilities, 15-16 years of age, report a significantly higher rate of sexual debut than adolescents with no disabilities. In a society where a young person with a disability often is considered to have an essentially asexual status, there can be several fronts for adolescents to fight. The survey Life and Health-Young People 2005 was completed by 3,084 adolescents attending m

Hepatocellular and extrahepatic cancer in patients with autoimmune hepatitis - a long-term follow-up study in 634 Swedish patients

Objectives. Cirrhosis is a well-known risk factor for hepatocellular cancer, but the true risk in autoimmune hepatitis (AIH) is scarcely studied. Other cancers may arise after prolonged use of immune-modulating drugs. The aim of this study was to investigate the cancer risk in a large cohort of AIH patients. Material and methods. Six hundred and thirty-four Swedish patients in a well-defined cohor

Nurr1 Is Required for Maintenance of Maturing and Adult Midbrain Dopamine Neurons

Transcription factors involved in the specification and differentiation of neurons often continue to be expressed in the adult brain, but remarkably little is known about their late functions. Nurr1, one such transcription factor, is essential for early differentiation of midbrain dopamine (mDA) neurons but continues to be expressed into adulthood. In Parkinson's disease, Nurr1 expression is dimin

Dynamic Mapping of Diesel Engine through System identification

From a control design point of view, modern diesel engines are dynamic, nonlinear, MIMO systems. This paper presents a method to find low-complexity black-box dynamic models suitable for model predictive control (MPC) of NOx and soot emissions based on on-line emissions measurements. A four-input-five-output representation of the engine is considered, with fuel injection timing, fuel injection dur

Narrow-Front Loop Migration in a Population of the Common Cuckoo Cuculus canorus, as Revealed by Satellite Telemetry.

Narrow migration corridors known in diurnal, social migrants such as raptors, storks and geese are thought to be caused by topographical leading line effects in combination with learning detailed routes across generations. Here, we document narrow-front migration in a nocturnal, solitary migrant, the common cuckoo Cuculus canorus, using satellite telemetry. We tracked the migration of adult cuckoo

A validation of the first genome-wide association study of calcaneus ultrasound parameters in the European Male Ageing Study

Background: A number of single nucleotide polymorphisms (SNPs) have been associated with broadband ultrasound attenuation (BUA) and speed of sound (SOS) as measured by quantitative ultrasound (QUS) at the calcaneus in the Framingham 100K genome-wide association study (GWAS) but have not been validated in independent studies. The aim of this analysis was to determine if these SNPs are associated wi

Jet energy measurement and its systematic uncertainty in proton-proton collisions at root s=7 TeV with the ATLAS detector

The jet energy scale (JES) and its systematic uncertainty are determined for jetsmeasured with the ATLAS detector using proton-proton collision data with a centre-of-mass energy of root s = 7 TeV corresponding to an integrated luminosity of 4.7 fb(-1). Jets are reconstructed from energy deposits forming topological clusters of calorimeter cells using the anti-kt algorithmwith distance parameters R

Residential mobility among foreign-born persons living in Sweden is associated with lower mortality.

here have been few longitudinal studies on the effect of within-country mobility on patterns of mortality in deceased foreign-born individuals. The results have varied; some studies have found that individuals who move around within the same country have better health status than those who do not change their place of residence. Other studies have shown that changing one’s place of residence leads

A Systematic Study of Gene Mutations in Urothelial Carcinoma; Inactivating Mutations in TSC2 and PIK3R1.

Abstract BACKGROUND: Urothelial carcinoma (UC) is characterized by frequent gene mutations of which activating mutations in FGFR3 are the most frequent. Several downstream targets of FGFR3 are also mutated in UC, e.g., PIK3CA, AKT1, and RAS. Most mutation studies of UCs have been focused on single or a few genes at the time or been performed on small sample series. This has limited the possibility

Climate change, carbon trading and societal self-defence

Markets, especially those for ‘fictitious’ commodities, are not the simple result of the gradual extension of exchange relations but social and political constructs. This paper discusses the socio-historical development of carbon markets and their application in the EU against the background of a Polanyian ‘double movement’: the reembedding of labour, money and land into social ties in the post-wa

Report of the Third International Workshop on Molecular Blood Group Genotyping

The Third International Society of Blood Transfusion Workshop on Molecular Blood Group Genotyping was held in 2008, with a feedback meeting at the International Society of Blood Transfusion Congress in Macao SAR, China. Thirty-three laboratories participated, eight less than in 2006. Six samples were distributed: sample 1 representing DNA from a sample referred because of abnormal serological resu

High-accuracy positioning: astrometry

The limiting accuracy for measuring the location of an optical image is set by diffraction and photon noise, i.e., by the dual wave-particle nature of light. A theoretical expression for the limiting accuracy is derived under idealized conditions and generalized to take into account more realistic circumstances, such as additive noise and finite pixel size. Its application is discussed in relation

Urologic disease in a resource-poor country

BACKGROUND: Understanding the role that urologic disease plays within central Haiti could lead to the development of sustainable and regionally appropriate urologic care. We aim to document the prevalence of urologic surgical disease presenting for treatment in central Haiti. METHODS: The present study is based on a retrospective review of surgical case logs at five Partners in Health and Zanmi La

Biocompatible multichannel electrodes for long-term neurophysiological studies and clinical therapy-Novel concepts and design

Chronic neural interfaces that are both structurally and functionally stable inside the brain over long time periods and that have minimal effects on the physiological conditions of the neural tissue to be studied hold great promise to become invaluable research and clinical tool in the near future. In this chapter, I will briefly review the state of the art of neural interfaces and the concepts b

Diffuse optical techniques applied to wood characterisation

We propose an optical method for non-invasive characterisation of wood samples based on two optical techniques: time-resolved diffuse optical spectroscopy and gas in scattering media absorption spectroscopy. While the latter is sensitive to gases present inside wood pores, the former extracts information on the bulk material regarding light scattering and absorption. Measurements on spruce samples

Past, present and future state of the biogeochemical Si cycle in the Baltic Sea

The Baltic Sea is one of many aquatic ecosystems that show long-term declines in dissolved silicate (DSi) concentrations due to anthropogenic alteration of the biogeochemical Si cycle. Reductions in DSi in aquatic ecosystems have been coupled to hydrological regulation reducing inputs, but also with eutrophication, although the relative significance of both processes remains unknown for the observ
