Hagopian WA, Erlich H, Lernmark Å, Rewers M, Ziegler AG, Simell O, Akolkar B, Vogt Jr R, Blair A, Ilonen J, Krischer J, She J, and the TEDDY Study Group. The Environmental Determinants of Diabetes in the Young (TEDDY): genetic criteria and international diabetes risk screening of 421 000 infants. Aims: The Environmental Determinants of Diabetes in the Young (TEDDY) study seeks to identify environm

Pediatric diaphyseal forearm fractures: epidemiology and treatment in an urban population during a 10-year period, with special attention to titanium elastic nailing and its complications.

This study aims to describe the epidemiology of pediatric diaphyseal forearm fractures in an urban population and the complications of titanium elastic nailing. The medical records of 456 consecutive fractures were reviewed. The annual incidence was 0.7/1000 children. Eighty-six (19%) fractures in 83 children were titanium elastic nailed. The complication rate was 24%. Dorsal entry to the radius w

Patients with irritable bowel syndrome and dysmotility express antibodies against gonadotropin-releasing hormone in serum.

Background The etiology of irritable bowel syndrome (IBS) and dysmotility is in most cases unknown. Organic, pathognomonic changes have not been described. We have previously demonstrated sporadic expressions of antibodies against gonadotropin-releasing hormone (GnRH) in serum from these patients. The aim of this study was to screen for the presence of GnRH antibodies in healthy subjects and patie

Swedish National Resource Centre for Physics Education celebrates its 20th anniversary

The Swedish National Resource Centre for Physics Education (fysik.org) was created at Lund University by the Swedish Government in 1994. Its 20th anniversary was celebrated 31 March to 1 April at the Island of Hven, which became an EPS historic site in 2013. The theme for the anniversary conference was 'From science education research to education—on research-based development projects.

Nerve compression induces activating transcription factor 3 in neurons and Schwann cells in diabetic rats.

Expression of transcription factor ATF3 in sensory neurons in dorsal root ganglion and in Schwann cells in sciatic nerve of diabetic (BB and Goto-Kakizaki rats; experimental models of types 1 and 2 diabetes, respectively) and healthy rats were examined by immunocytochemistry after nerve compression (silicone tube) for 3, 6 or 14 days. ATF3-stained sensory neurons in dorsal root ganglia and Schwann

Increased orexin levels in the cerebrospinal fluid the first year after a suicide attempt.

BACKGROUND: The orexins (hypocretins) and cocaine and amphetamine regulated transcript (CART) are hypothalamic peptides involved in the regulation of sleep and appetite. We have previously shown that levels of both orexin-A and CART in the cerebrospinal fluid (CSF) are related to specific psychiatric symptoms. METHODS: Ten patients took part in lumbar punctures and psychiatric evaluations in conju

A Comparison of A Single and Multiphase Jets in a Crossflow Using LES

Large eddy simulations (LES) are performed for single and multiphase jets in crossflow (JICF). The multiphase JICF are compared to the single-phase case for the same momentum and mass flow ratios but with droplets of different sizes. Multiphase JICF have stronger counterrotating vortex pairs (CVPs) than a corresponding single-phase JICF. Moreover, their trajectories are higher and their induced wa

Who is performing surgery in low-income settings: a countrywide inventory of the surgical workforce distribution and scope of practice in Sierra Leone.

Scope of practice and in-country distribution of surgical providers in low-income countries remains insufficiently described. Through a nationwide comprehensive inventory of surgical procedures and providers in Sierra Leone, we aimed to present the geographic distribution, medical training, and productivity of surgical providers in a low-income country.

Induction of T helper 2 responses against human Apolipoprotein B100 does not affect atherosclerosis in ApoE-/- mice.

Immune responses against LDL antigens have been found to play an important modulatory role in atherosclerosis. Immunization with homologous oxidized LDL, as well as human apolipoprotein B100 (ApoB)-derived peptides, inhibit atherosclerosis in hypercholesterolemic animal models of atherosclerosis. However, the role of antigen-specific Th2 responses in atherosclerosis remains to be fully clarified.

Off-axis reflection zone plate for quantitative soft x-ray source characterization

A compact system for high-resolution spectroscopy and quantitative photon flux and brilliance measurements of pulsed soft x-ray sources is described. The calibrated system combines a novel elliptical off-axis reflection zone plate with charge-coupled device detection for simultaneous spectral and spatial measurements. Experiments on a water-window droplet-target laser-plasma source demonstrate lam

The effect of land surface changes on Eemian climate

Transient experiments for the Eemian (128-113 ky BP) were performed with a complex, coupled earth system model, including atmosphere, ocean, terrestrial biosphere and marine biogeochemistry. In order to investigate the effect of land surface parameters (background albedo, vegetation and tree fraction and roughness length) on the simulated changes during the Eemian, simulations with interactive cou

Open-label, clinical phase I studies of tasquinimod in patients with castration-resistant prostate cancer.

Background:Tasquinimod is a quinoline-3-carboxamide derivative with anti-angiogenic activity. Two open-label phase I clinical trials in patients were conducted to evaluate the safety and tolerability of tasquinimod, with additional pharmacokinetic and efficacy assessments.Methods:Patients with castration-resistant prostate cancer with no previous chemotherapy were enrolled in this study. The patie

Comparison of patients with early-phase arrhythmogenic right ventricular cardiomyopathy and right ventricular outflow tract ventricular tachycardia.

Differentiation between early-phase arrhythmogenic right ventricular cardiomyopathy (ARVC) and right ventricular outflow tract (RVOT)-ventricular tachycardia (VT) can be challenging, and correct diagnosis is important. We compared electrocardiogram (ECG) parameters and morphological right ventricular (RV) abnormalities and investigated if ECG and cardiac imaging can help to discriminate early-phas

Stopping a roller coaster train

A roller coaster ride comes to an end. Magnets on the train induce eddy currents in the braking fins, giving a smooth rise in braking force as the remaining kinetic energy is absorbed by the brakes and converted to thermal energy. In this paper an IR camera was used to monitor the temperature of the first braking fin, before, during and after the passage of a train. In addition, the resulting acce

Cancer risk after hospitalization for osteoporosis in Sweden.

Osteoporosis is common in the elderly, and it is associated with lifetime exposure to endogenous hormones and vitamin D intake, both of which are associated with cancer development. The association of osteoporosis with subsequent cancer has not been established, and hence we examined here the overall and site-specific cancer risks among Swedish individuals after hospitalization for osteoporosis. P

Haemodynamic effects of -75 mmHg negative pressure therapy in a porcine sternotomy wound model.

Previous research has shown -125 mmHg to be the optimal negative pressure for creating an environment that promotes wound healing, and this has therefore been adopted as a standard pressure for patients with deep sternal wound infection. However, it has not yet been clearly shown that -125 mmHg is the optimal pressure from a haemodynamic point of view. Furthermore, there have been reports of cardi

Improved performance characteristics of the von Willebrand factor ristocetin cofactor activity assay using a novel automated assay protocol.

Summary Background, objectives and methods: An accurate, sensitive and precise assay for reliable determination of the ristocetin cofactor activity of von Willebrand factor (VWF:RCo) in plasma and von Willebrand Factor (VWF)-containing concentrates has been evaluated. The assay is based on a commercially available automated protocol with modifications including a combination of adding additional r

Increased Tissue Endothelin-1 and Endothelin-B Receptor Expression in Temporal Arteries from Patients with Giant Cell Arteritis.

PURPOSE: Endothelin (ET)-1 has been implicated in the atherosclerotic process and during inflammation. Similarity in the development process of giant cell arteritis (GCA) and atherosclerosis exists. Several ET receptor antagonists have been developed, principally to target cardiovascular disease states. High doses of corticosteroids currently are used in the treatment of GCA, whereas other treatme
