Genome-wide, high-content siRNA screening identifies the Alzheimer’s genetic risk factor FERMT2 as a major modulator of APP metabolism

Genome-wide association studies (GWASs) have identified 19 susceptibility loci for Alzheimer’s disease (AD). However, understanding how these genes are involved in the pathophysiology of AD is one of the main challenges of the “post-GWAS” era. At least 123 genes are located within the 19 susceptibility loci; hence, a conventional approach (studying the genes one by one) would not be time- and cost

Growth and optical properties of InxGa1−xP nanowires synthesized by selective-area epitaxy

Ternary III–V nanowires (NWs) cover a wide range of wavelengths in the solar spectrum and would greatly benefit from being synthesized as position-controlled arrays for improved vertical yield, reproducibility, and tunable optical absorption. Here, we report on successful selective-area epitaxy of metal-particle-free vertical InxGa1−xP NW arrays using metal–organic vapor phase epitaxy and detail t

In vivo measurements of T2 relaxation time of mouse lungs during inspiration and expiration

Purpose: The interest in measurements of magnetic resonance imaging relaxation times, T1, T2, T2∗, with intention to characterize healthy and diseased lungs has increased recently. Animal studies play an important role in this context providing models for understanding and linking the measured relaxation time changes to the underlying physiology or disease. The aim of this work was to study how th

Comparison of a novel porous titanium construct (Regenerex®) to a well proven porous coated tibial surface in cementless total knee arthroplasty — A prospective randomized RSA study with two-year follow-up

Background Regenerex is a novel porous titanium construct with a three-dimensional porous structure and biomechanical characteristics close to that of normal trabecular bone. The aim of this study was to compare this novel construct to a well-proven porous plasma sprayed tibial (PPS) implant after total knee arthroplasty. Methods Sixty-one patients scheduled for an uncemented TKA were randomized t

Adhesion G protein-coupled receptor G1 (ADGRG1/GPR56) and pancreatic β-cell function

Context: Adhesion G protein-coupled receptor (GPCR)-G1 (ADGRG1) is the most abundant GPCR in human pancreatic islets, but its role in islet function is unclear. Objective: Investigate how ADGRG1 expression and activation by its ligand, collagen III, impacts β-cell function in normal and type 2 diabetic (T2D) islets. Design: Genes associated with the ADGRG1 in human islets was probed by RNA-sequenc

Information and/or medical technology staff experience with regulations for medical information systems and medical devices

Objectives Regulations heavily control medical technology (MT), which often includes information technology (IT), but staff experiences related to these regulations are unknown. The study aim was to assess Swedish IT/MT staff experiences regarding regulations for medical devices and medical information systems. Methods An anonymous, ten-item, self-report questionnaire was administered to IT and MT

Bone-targeted novel cytotoxic polybisphosphonate conjugate in castration-resistant prostate cancer : A multicenter phase 1 study

Background: Osteodex (ODX) is a cytotoxic bone-targeting polybisphosphonate, intended for treatment of bone metastasis from castration-resistant prostate cancer (CRPC). The primary objective of this study was to describe the tolerability and toxicity of such treatment by defining its maximum tolerated dose (MTD) and dose-limiting toxicity (DLT). Patients and Methods: Twenty-eight patients with cas

ANCA-associated glomerulonephritis : Risk factors for renal relapse

Relapse in ANCA-associated vasculitis (AAV) has been studied previously, but there are few studies on renal relapse in particular. Identifying patients at high risk of renal relapse may aid in optimizing clinical management. We investigated which clinical and histological parameters are risk factors for renal relapse in ANCA-associated glomerulonephritis (AAGN). Patients (n = 174) were newly diagn

Internalization of secreted antigen-targeted antibodies by the neonatal Fc receptor for precision imaging of the androgen receptor axis

Targeting the androgen receptor (AR) pathway prolongs survival in patients with prostate cancer, but resistance rapidly develops. Understanding this resistance is confounded by a lack of noninvasive means to assess AR activity in vivo. We report intracellular accumulation of a secreted antigen-targeted antibody (SATA) that can be used to characterize disease, guide therapy, and monitor response. A

Innovative Gliadin/Glutenin and Modified Potato Starch Green Composites : Chemistry, Structure, and Functionality Induced by Processing

In this study, we combined two wheat proteins, gliadin (Gli)/glutenin (GT), and modified potato starch (MPS) into composites using extrusion. In the Gli/GT-MPS composites, we studied the structural dynamics of proteins and starch, protein-starch interactions, protein properties, and composite morphology in relation to mechanical and barrier properties. Materials with different ratios of Gli/GT and

Cohort patterns in Rana tadpole metamorphosis

This study explores the cohort patterns in a size versus time plot of individual metamorphs of Rana tadpoles. This meta-study was based on a number of studies where any of three species of Rana tadpoles were raised in tanks under various treatments (variation in source pond, tadpole density, drying regime, hatching date, food level and competitors). A frequent pattern was found where there was an

Glycogen metabolism in the glucose-sensing and supply-driven β-cell

Glycogen metabolism in β-cells may affect downstream metabolic pathways controlling insulin release. We examined glycogen metabolism in human islets and in the rodent-derived INS-1 832/13 β-cells and found them to express the same isoforms of key enzymes required for glycogen metabolism. Our findings indicate that glycogenesis is insulin-independent but influenced by extracellular glucose concentr

Influence of geolocation and ethnicity on the phenotypic expression of primary Sjögren's syndrome at diagnosis in 8310 patients : A cross-sectional study from the Big Data Sjögren Project Consortium

Objectives To analyse the influence of geolocation and ethnicity on the clinical presentation of primary Sjögren's syndrome (SjS) at diagnosis. Methods The Big Data Sjögren Project Consortium is an international, multicentre registry designed in 2014. By January 2016, 20 centres from five continents were participating. Multivariable logistic regression analyses were performed. Results We included

Somatic mosaicism in hemophilia A: A fairly common event

Mutations in the large gene of clotting factor VIII (FVIII) are the most common events leading to severe human bleeding disorder. The high proportion of de novo mutations observed in this gene raises the possibility that a significant proportion of such mutations does not derive from a single germ cell but instead should be attributed to a germline or somatic mosaic originating from a mutation dur
