Malignant melanoma is one of the most aggressive tumors which often gives metastasis to distant organs thereby limiting the chances of survival. Brain metastasis occurs in nearly half of the advanced tumors. In order to improve outcome early diagnosis is important. The discovery and better understanding of genetic and epigenetic changes is essential for developing new effective therapies, which ca

Early onset of type 1 diabetes and educational field at upper secondary and university level : Is own experience an asset for a health care career?

Ill health in early life has a significant negative impact on school grades, grade repetition, educational level, and labormarket outcomes. However, less is known about qualitative socio-economic consequences of a health shock in childhood or adolescence. We investigate the relationship between onset of type 1 diabetes up to age 15 and the probability of choosing and completing a health-oriented p

Extreme MHC class i diversity in the sedge warbler (Acrocephalus schoenobaenus); Selection patterns and allelic divergence suggest that different genes have different functions

Background: Recent work suggests that gene duplications may play an important role in the evolution of immunity genes. Passerine birds, and in particular Sylvioidea warblers, have highly duplicated major histocompatibility complex (MHC) genes, which are key in immunity, compared to other vertebrates. However, reasons for this high MHC gene copy number are yet unclear. High-throughput sequencing (H

Risk of eating disorders in immigrant populations

Objective: The risk of certain psychiatric disorders is elevated among immigrants. To date, no population studies on immigrant health have addressed eating disorders. We examined whether risk of eating disorders in first- and second-generation immigrants differs from native-born Danes and Swedes. Method: All individuals born 1984–2002 (Danish cohort) and 1989–1999 (Swedish cohort) and residing in

Democratic Innovations: Reinforcing or Changing Perceptions of Trust?

Declining trust in representative institutions is considered one of the most significant political problems of our time. It is often suggested that democratic innovations—or mechanisms which aim to increase and deepen citizen participation in the political decision-making process—can help reverse this trend. However, empirical research about actual effects of participation on trust is scarce, and

Molecular properties of astaxanthin in water/ethanol solutions from computer simulations

Astaxanthin (AXT) is a reference model of xanthophyll carotenoids, which is used in medicine and food industry, and has potential applications in nanotechnology. Because of its importance, there is a great interest in understanding its molecular properties and aggregation mechanism in water and mixed solvents. In this paper, we report a novel model of AXT for molecular dynamics simulation. The mod

Combustion characteristics of well-dispersed boron submicroparticles and plasma effect

Boron is an attractive high-energy fuel additive. But it could not burn efficiently in practical systems due to its high ignition temperature and slow burning velocity. Finding methods to enhance the combustion of boron is desired. This work focused on the combustion characteristics of boron submicroparticles with and without plasma discharges in a hot environment supported by CH4/N2/O2 flat flame

Different emissive states in the bulk and at the surface of methylammonium lead bromide perovskite revealed by two-photon micro-spectroscopy and lifetime measurements

Two photon photoluminescence (2PPL) from single crystals of methyl ammonium lead bromide (CH3NH3PbBr3, MAPbBr3) is studied. We observe two components in the 2PPL spectra, which we assign to the photoluminescence (PL) from the carrier recombination at the band edge and the recombination due to self-trapping of excitons. The PL Stokes shift of self-trapped excitons is about 100 meV from the band-ga

Comprehensive CO detection in flames using femtosecond two-photon laser-induced fluorescence

We demonstrate a femtosecond two-photon laser-induced fluorescence (fs-TPLIF) technique for sensitive CO detection, using a 230 nm pulse of 9 µJ and 45 fs. The advantages of fs-TPLIF in excitation of molecular species were analyzed. Spectra of CO fs-TPLIF were recorded in stable laminar flames spatially resolved across the flame front. A hot band (1, n) together with the conventional band (0, n) o

The impact of methylation quantitative trait loci (mQTLs) on active smoking-related DNA methylation changes

Background: Methylation quantitative trait loci (mQTLs) are the genetic variants that may affect the DNA methylation patterns of CpG sites. However, their roles in influencing the disturbances of smoking-related epigenetic changes have not been well established. This study was conducted to address whether mQTLs exist in the vicinity of smoking-related CpG sites (±50kb) and to examine their associa
