Generating Diffusion MRI Scalar Maps from T1 Weighted Images Using Generative Adversarial Networks

Diffusion magnetic resonance imaging (diffusion MRI) is a non-invasive microstructure assessment technique. Scalar measures, such as FA (fractional anisotropy) and MD (mean diffusivity), quantifying micro-structural tissue properties can be obtained using diffusion models and data processing pipelines. However, it is costly and time consuming to collect high quality diffusion data. Here, we theref

Diabetes resistance in the BB rat maps to a body weight regulator on chromosome 2

Insulin-dependent Type 1 diabetes mellitus is the most common chronic disorder in children and young adults. The genetics, etiology and pathogenesis is complicated by the apparent presence of several genetic region; that contribute to susceptibility. The genetic dissection of Type 1 autoimmune diabetes in the inbred BioBreeding (BB) rat which closely resembles the human disorder was shown to invol

Glutamate decarboxylase (GAD65) and tyrosine phosphatase-like protein (IA-2) autoantibodies index in a regional population is related to glucose intolerance and body mass index

Aims/hypothesis. Our aims were to investigate the concentrations and prevalence of autoantibodies against the Mr 65.000 isoform of glutamate decarboxylase (GAD65) and the tyrosine phosphatase-like protein (IA-2) in adults and to test the hypothesis that GAD65 and IA-2 autoantibodies in a regional population are related to abnormal oral glucose tolerance. Methods. We analysed serum from 2157 Swedis

A diabetogenic gene prevents T cells from receiving costimulatory signals

T cell fate following antigen encounter is determined by several intracellular signals generated by the interaction of the T cell with an antigen-presenting cell. In the periphery activation requires T cell receptor signaling (signal one) in combination with costimulatory signals (signal two), usually provided through the cognate interaction of CD28 and B7 molecules. Provision of signal one alone

Simultaneous Hot Electron and Hole Injection upon Excitation of Gold Surface Plasmon

We have successfully investigated the simultaneous injection of hot electrons and holes upon excitation of gold localized surface plasmon resonance (LSPR). The studies were performed on all-solid-state plasmonic system composed of titanium dioxide (TiO2)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) p-n junctions with gold nanoparticles (Au NPs). The study revealed that b

Naturvård - segregerad från eller integrerad i jordbrukslandskapet?

Naturvårdens mål är att bevara biologisk mångfald (gener, arter och livsmiljöer) ochnaturliga ekosystemprocesser, men också att möta människors behov av att tillgodogöra sig de tjänster som naturen ger. Under de senaste åren har en polariserad debatt uppstått som ställer dessa målsättningar emot varandra. Sett ur ett bredare perspektiv är det dock möjligt att hitta lösningar som kombinerar bägge d

Are Perinatal Events Risk Factors for Childhood Thyroid Autoimmunity?

Background: Environmental and genetic factors possibly trigger thyroid autoimmunity. Studies on perinatal risk factors for childhood thyroid autoimmunity are sparse.Objectives: The aim was to investigate if perinatal factors, family history of autoimmune diseases, and HLA-DQ genotypes contribute to thyroid autoimmunity in the Diabetes Prediction in Skåne (DiPiS) study.Methods: Samples from 1,874 t

Blocking the charge recombination with diiodide radicals by TiO2 compact layer in dye-sensitized solar cells

The addition of a compact titanium dioxide (TiO2) layer between the fluorine-doped tin oxide (FTO) coated glass substrate and the mesoporous TiO2 layer in the dye-sensitized solar cell (DSC) based on the iodide/triiodide redox couple (I−/I3−) is known to improve its current-voltage characteristics. The compact layer decreases the recombination of electrons extracted through the FTO layer with I3−

Vaccination mot typ 1-diabetes framme vid kliniska försöksstadiet

The occurrence of type I diabetes is associated with autoimmunity against insulin, glutamate decarboxylase (GAD65) and the transmembrane protein IA-2. Experiments in the spontaneously diabetic NOD mouse and the BB rat have shown early autoantigen treatment to confer protection from diabetes. The question remains of whether human type I diabetes can be prevented by autoantigen 'vaccination'.

A conformation-dependent epitope in Addison's disease and other endocrinological autoimmune diseases maps to a carboxyl-terminal functional domain of human steroid 21-hydroxylase

Idiopathic Addison's disease develops as a consequence of autoimmune destruction of steroid-producing cells in the adrenal gland. A major autoantigen is 21-hydroxylase (21OH; P450c21), which is involved in the biosynthesis of cortisol and aldosterone in the adrenal cortex. We selected a number of functionally important 21OH amino acid substitutions, found in patients with congenital adrenal hyperp

Quasi One-Dimensional Metal-Semiconductor Heterostructures

The band offsets occurring at the abrupt heterointerfaces of suitable material combinations offer a powerful design tool for high performance or even new kinds of devices. Because of a large variety of applications for metal-semiconductor heterostructures and the promise of low-dimensional systems to present exceptional device characteristics, nanowire heterostructures gained particular interest o

Association of Preterm Birth with Risk of Ischemic Heart Disease in Adulthood

Importance: Preterm birth has previously been associated with increased risks of hypertension and diabetes, but not ischemic heart disease (IHD), in adulthood. The reasons for this lack of association with IHD despite associations with its risk factors have been elusive, but may be associated with methodologic issues, such as survivor bias, in prior studies. Objective: To determine whether preterm

The X-Linked DDX3X RNA Helicase Dictates Translation Reprogramming and Metastasis in Melanoma

The X-linked DDX3X gene encodes an ATP-dependent DEAD-box RNA helicase frequently altered in various human cancers, including melanomas. Despite its important roles in translation and splicing, how DDX3X dysfunction specifically rewires gene expression in melanoma remains completely unknown. Here, we uncover a DDX3X-driven post-transcriptional program that dictates melanoma phenotype and poor dise

Multicenter Analysis of Endovascular Aortic Arch In Situ Stent-Graft Fenestrations for Aortic Arch Pathologies

Background: In situ fenestration of aortic stent grafts for treatment of aortic arch aneurysms is a new option for endovascular aortic arch repair. So far, only few reports have shown perioperative and short-term results of in situ fenestrations for aortic arch diseases. We present the multicenter experience with the aortic arch in situ fenestration technique documented in the AARCHIF registry for

Fracture mechanics for membranes : The 15th European Conference of Fracture (ECF15)

During fracture of membranes loading often produces buckles above and below the crack surface. This changes the stress state surrounding the crack-tip and stresses in the neighbourhood of the crack-tip posses a weaker singularity than r-1/2. As a result, fracture occurs when the crack-tip stress distribution is different as compared with that when buckling is artificially prevented. Therefore the During fracture of membranes loading often produces buckles above and below the cracksurface. This changes the stress state surrounding the crack-tip and stresses in theneighbourhood of the crack-tip posses a weaker singularity than r-1/2. As a result, fractureoccurs when the crack-tip stress distribution is different as compared with that when bucklingis artificially prevented. Therefore the cond

Gastrointestinal dysfunction in patients and mice expressing the autism-associated r451c mutation in neuroligin-3

Gastrointestinal (GI) problems constitute an important comorbidity in many patients with autism. Multiple mutations in the neuroligin family of synaptic adhesion molecules are implicated in autism, however whether they are expressed and impact GI function via changes in the enteric nervous system is unknown. We report the GI symptoms of two brothers with autism and an R451C mutation in Nlgn3 encod

Ecological Consequences of Animal Migration : Prey Partial Migration Affects Predator Ecology and Prey Communities

Patterns of animal migration and the ecological forces that shape them have been studied for centuries. Yet ecological impacts caused by the migration, such as altered predator–prey interactions and effects on community structure, remain poorly understood. This is to a large extent due to the scarcity of naturally replicated migration systems with negative controls, that is, ecosystems without mig
