Encapsulating reacting biological or chemical samples in microfluidic droplets has the great advantage over single-phase flows of providing separate reaction compartments. These compartments can be filled in a combinatoric way and prevent the sample from adsorbing to the channel walls. In recent years, small-angle X-ray scattering (SAXS) in combination with microfluidics has evolved as a nanoscale
Understanding how environmental variation influences even cryptic traits is important to clarify the roles of selection and developmental constraints in past evolutionary divergence and to predict future adaptation under environmental change. Female yellow dung flies (Scathophaga stercoraria) typically have three sperm storage compartments (3S), but occasionally four (4S). More spermathecae are th
In Alzheimer's disease, post-mortem studies have shown that the first cortical site where neurofibrillary tangles appear is the transentorhinal region, a subregion within the medial temporal lobe that largely overlaps with Brodmann area 35, and the entorhinal cortex. Here we used tau-PET imaging to investigate the sequence of tau pathology progression within the human medial temporal lobe and acro
Tau protein neurofibrillary tangles are closely linked to neuronal/synaptic loss and cognitive decline in Alzheimer's disease and related dementias. Our knowledge of the pattern of neurofibrillary tangle progression in the human brain, critical to the development of imaging biomarkers and interpretation of in vivo imaging studies in Alzheimer's disease, is based on conventional two-dimensional his
Background: Knowledge on tuberculosis (TB) infection epidemiology in women of reproductive age living in TB-endemic areas is limited. We used a composite definition of TB infection in a cohort of pregnant women recruited in an Ethiopian city as a model for TB exposure patterns, and to identify factors associated with TB infection. Methods: Women seeking antenatal care at public health facilities u
Background. Renal biopsies are essential in nephrology but they are invasive and complications can occur. The aim of this study was to explore clinical parameters that can be used as predictors for biopsy complications. Methods. Clinical parameters such as demographics, biopsy indications, serology, comorbidities and clinical chemistry were retrieved from a regional biopsy registry between 2006 an
Billions of specimens can be found in natural history museum collections around the world, holding potential molecular secrets to be unveiled. Among them are intriguing specimens of rare families of moths that, while represented in morphology-based works, are only beginning to be included in genomic studies: Pseudobistonidae, Sematuridae, and Epicopeiidae. These three families are part of the supe
BackgroundThe etiology of male breast cancer (MBC) is poorly understood. In particular, the extent to which the genetic basis of MBC differs from female breast cancer (FBC) is unknown. A previous genome-wide association study of MBC identified 2 predisposition loci for the disease, both of which were also associated with risk of FBC.MethodsWe performed genome-wide single nucleotide polymorphism ge
Intron splicing is an essential event in post-transcriptional RNA processing in plant mitochondria, which requires the participation of diverse nuclear-encoded splicing factors. However, it is presently unclear how these proteins cooperatively take part in the splicing of specific introns. In this study, we characterized a nuclear-encoded mitochondrial P-type pentatricopeptide repeat (PPR) protein
This PhD project balances an interest in social work and its prospects for deliv-ering emancipation or relief from stigma, etc. through motivational agency, on the one hand, with an attentiveness to recent developments in Scandinavian criminal policy, on the other. In my attempts at »bridging« these interests I have come to focus on offender rehabilitation. In this short paper I shall present the
Background: The functional impact of breathlessness is assessed using the modified Medical Research Council (mMRC) scale for chronic respiratory disease and with the New York Heart Association Functional Classification (NYHA) scale for heart failure. We evaluated agreement between the scales and their concurrent validity with other clinically relevant patient-reported outcomes in cardiorespiratory
Uppåkra har länge framstått som en solitär i ett tomt landskap. Bakgrunden till denna uppfattning, snarare än realitet, kommer av det faktum att få arkeologiska undersökningar har gjorts i centralplatsens närhet. Inom en fem kilometers radie runt Uppåkra har emellertid flera undersökningar utförts under 2000-talet inom uppdragsarkeologin. Dessa har skapat en hälsosam kontrast till den fyndrika pla
Variations in the phosphorylation and glycosylation patterns of the common κ-casein (CN) variants A and B have been explored, whereas studies on variant E heterogeneity are scarce. This study reports for the first time the detailed phosphorylation and glycosylation pattern of the κ-CN variant E in comparison with variants A and B. Individual cow milk samples representing κ-CN genotype EE (n = 12)
Stephen Graham and Simon Marvin’s Splintering Urbanism: Networked Infrastructures, Tech- nological Mobilities and the Urban Condition (2001) brought the study of infrastructure to the core of urban studies and inspired the “infrastructural turn” in the social sciences more widely. The book catalyzed a rich trove of research on how technology and society are impli- cated in the production of contem
We investigate the effects of offshoring on job security using matched employer-employee data from Sweden. Between 1997 and 2011, the share of offshoring firms fell from around 25 to 22% while offshoring per worker within offshoring firms almost doubled. We use this variation to contribute to the literature by examining the effects of the neighboring firms’ offshoring (external offshoring) on job
Alzheimer’s Disease (AD) is a devastating neurodegenerative disease associated with massive neuronal cell death during its pathology. The involvement of the amyloid β 42 (Aβ42) peptideand its role in neurotoxicity is now well established. It is known that the production of oligomers during the aggregation of Aβ42 into highly ordered fibrils is responsible for neuronal cell death. However, the effo
