Association of etiological factors across the extreme end and continuous variation in disordered eating in female Swedish twins

BackgroundAccumulating evidence suggests that many psychiatric disorders etiologically represent the extreme end of dimensionally distributed features rather than distinct entities. The extent to which this applies to eating disorders (EDs) is unknown.MethodsWe investigated if there is similar etiology in (a) the continuous distribution of the Eating Disorder Inventory-2 (EDI-2), (b) the extremes

Human sperm displays rapid responses to diet

The global rise in obesity and steady decline in sperm quality are two alarming trends that have emerged during recent decades. In parallel, evidence from model organisms shows that paternal diet can affect offspring metabolic health in a process involving sperm tRNA-derived small RNA (tsRNA). Here, we report that human sperm are acutely sensitive to nutrient flux, both in terms of sperm motility

Water channel pore size determines exclusion properties but not solute selectivity

Aquaporins (AQPs) are a ubiquitous family of transmembrane water channel proteins. A subgroup of AQP water channels also facilitates transmembrane diffusion of small, polar solutes. A constriction within the pore, the aromatic/arginine (ar/R) selectivity filter, is thought to control solute permeability: previous studies on single representative water channel proteins suggest narrow channels condu

Inhibition of histone demethylases LSD1 and UTX regulates ERα signaling in breast cancer

In breast cancer, Lysine-specific demethylase-1 (LSD1) and other lysine demethylases (KDMs), such as Lysine-specific demethylase 6A also known as Ubiquitously transcribed tetratricopeptide repeat, X chromosome (UTX), are co-expressed and co-localize with estrogen receptors (ERs), suggesting the potential use of hybrid (epi)molecules to target histone methylation and therefore regulate/redirect hor

Mutual fund selection for realistically short samples

Performance of mutual fund selection methods is typically assessed using long samples (long time series). We investigate how well the methods perform in shorter samples. We carry out an extensive simulation study based on empirically motivated skill distributions. For both short and long samples, we present evidence of large differences in performance between popular fund selection methods. In an

Sibling relationships, personality traits, emotional, and behavioral difficulties in autism spectrum disorders

This study focused on parents' perceptions of the quality of sibling relationship and its association with some behavioral and emotional characteristics of the typically developing sibling. The participants were parents of children with autism spectrum disorder and typically developing siblings. The sample size was 43. The group comprised 14 fathers (32.6%) and 29 mothers (67.4%) aged 33-53 years

Risk factors for subarachnoid haemorrhage : a nationwide cohort of 950 000 adults

BACKGROUND: Subarachnoid haemorrhage (SAH) is a devastating disease, with high mortality rate and substantial disability among survivors. Its causes are poorly understood. We aimed to investigate risk factors for SAH using a novel nationwide cohort consortium. METHODS: We obtained individual participant data of 949 683 persons (330 334 women) between 25 and 90 years old, with no history of SAH at

Single-Phase Borophene on Ir(111) : Formation, Structure, and Decoupling from the Support

Artificial two-dimensional (2D) materials, which host electronic or spatial structure and properties not typical for their bulk allotropes, can be grown epitaxially on atomically flat surfaces; the design and investigation of these materials are thus at the forefront of current research. Here we report the formation of borophene, a planar boron allotrope, on the surface of Ir(111) by exposing it t

RIFM fragrance ingredient safety assessment, p-tolyl acetate, CAS Registry Number 140-39-6

The existing information supports the use of this material as described in this safety assessment. p-Tolyl acetate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog ethyl p-tolyl carbonate (CAS # 22719-81-9) show that p-tolyl acetate

RIFM fragrance ingredient safety assessment, isobutyl alcohol, CAS Registry Number 78-83-1

The existing information supports the use of this material as described in this safety assessment. Isobutyl alcohol was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that isobutyl alcohol is not genotoxic. Data on isobutyl alcohol provide a calculated M

We present new geochronological data on dolerites from the Chaya dyke swarm of the Baikal inlier of the Siberian craton. The U-Pb dating of baddeleyite from one dyke located at the SW end of the Chaya dyke swarm yielded an age of 1752±6 Ma, similar to the previously obtained age of a dyke in the NE end of this swarm. These ages establish an age of 1752 Ma for a unified Chaya dyke swarm that extend

Change in baseline characteristics over 20 years of adults with growth hormone (GH) deficiency on GH replacement therapy

Objective: Clinical observations over time of adults with growth hormone (GH) deficiency (GHD) have indicated a shift in patient characteristics at diagnosis. The objective of this study was to compare baseline characteristics of patients diagnosed with adult-onset GHD naive to GH replacement during t hree study periods (1994-1999 (P1), 2000-2004 (P2), and 2005-2012 (P3)) using the KIMS (Pfizer's

Risk for hip fracture before and after total knee replacement in Sweden

Summary: We studied the risk for hip fracture before and after total knee replacement (TKR) in the entire population in Sweden. Women and men had a low risk for hip fracture before TKR but an increased risk the first year after TKR. Purpose: It is known that osteoarthritis is associated with high bone mass. We therefore studied the risk of hip fracture before and after total knee replacement (TKR)

Insufficient mixing of thawed serum samples leading to erroneous results–experience from a field study and use of a correction procedure

Incorrect analysis results that are close to expected might not be recognized in scientific studies or routine patient care. In two field studies we obtained unexpected results in a large number of samples. The present study aimed to identify the source of error in the samples from these studies and to validate a method to obtain correct results. Pre-analytical procedures were scrutinized, giving

Depression Severity, but Not Cognitive Impairment or Frailty, is Associated with Disability in Late-Life Depression

Objectives: Assess the relationship of cognitive impairment to disability, accounting for depression severity and frailty, among older adults with late-life depression (LLD). Methods: Data were analyzed from 78 community-dwelling older adults with LLD and without dementia (age M = 71.9; SD = 6.1). Cognitive functioning was assessed using a comprehensive neuropsychological battery. Depression sever

Rationale and design of the AFFIRM-AHF trial : a randomised, double-blind, placebo-controlled trial comparing the effect of intravenous ferric carboxymaltose on hospitalisations and mortality in iron-deficient patients admitted for acute heart failure

Aims: Iron deficiency (ID) is a common co-morbidity in heart failure (HF), associated with impaired functional capacity, poor quality of life and increased morbidity and mortality. Treatment with intravenous (i.v.) ferric carboxymaltose (FCM) has shown improvements in functional capacity, symptoms and quality of life in stable HF patients with reduced ejection fraction. The effect of i.v. iron sup
