Muller cells are the principle glia cells of the retina that maintain the integrity and function of the retina and are thought to support and protect neurons during various insults. α2-adrenergic receptor agonists have been shown to be neuroprotective and Mu[[unable to display character: ̈]]ller cells are suggested to take part in these effects.

The aim of the current study was to compare lower urinary tract symptoms (LUTS), erectile dysfunction (ED), and quality of life (QoL) in poststroke and healthy men. Thirty poststroke men with stroke-related LUTS, and as controls, 96 healthy men participated in this controlled, cross-sectional study. Participants filled in the Danish Prostate Symptom Score (DAN-PSS-1) Questionnaire, the Internation

Spasticity is a locomotory disability that is common after injury to the spinal cord. Monoamines such as serotonin and dopamine controls the activation of motoneurons, which in turn affects muscle. Aromatic L-amino acid decarboxylase (AADC) catalyzes formation of serotonin from 5-hydroxytryptophan and dopamine from L-dihydroxyphenylalanine. To study if there are cells in the primate spinal cord th

Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management schemes that may mitigate potential ecological harm by increasing species richness and boosting related ecosystem services to agroecosystems. What remains unclear is the extent to wh

Chromites from Middle Ordovician fossil L chondrites and from matrix and shock-melt veins in Catherwood, Tenham, and Coorara L chondrites were studied using Raman spectroscopy and TEM. Raman spectra of chromites from fossil L chondrites showed similarities with chromites from matrix and shock-melt veins in the studied L chondrite falls and finds. Chromites from shock-melt veins of L chondrites sho

Posttraumatic stress disorder (PTSD) is associated with increased risk for Type 2 diabetes and cardiovascular disease (cardiometabolic disease), warranting research into targeted prevention strategies. In the present case–control study of 160 young (mean age 32.7 years) male military veterans, we aimed to assess whether PTSD status predicted increased markers of cardiometabolic risk in otherwise h

BACKGROUND. Understanding the genetic architecture of cardiac structure and function may help to prevent and treat heart disease. This investigation sought to identify common genetic variations associated with inter-individual variability in cardiac structure and function. METHODS. A GWAS meta-analysis of echocardiographic traits was performed, including 46,533 individuals from 30 studies (EchoGen

This report deals with the identification of ATP/ADP translocase genes. In rickettsial species such as Rickettsia prowazekii, which is the cause of epidemic typhus in humans, the utilisation of host cell ATP is the major way that this bacterium employ its toxicity in the host cell. This obligate intracellular bacterium is an energy-parasite. In the genome of R. prowazekii there are five homologs o

I det här arbetet har de neurotoxiska effekterna av paraquat och roundup studerats, efter en neonatal lågdos-exponering. Paraquat förekommer i miljön och dess likhet med det neurotoxiska ämnet l-methyl-4-phenyl-1,2,3,6-tetrahydropyridin (MPTP) gör den intressant i neurotoxikologiskt avseende. Detta arbete omfattar tre olika försök. I försök 1) exponerades möss neonatalt for paraquat, dessa djur av

We investigated whether dementia risk factors were associated with prodromal Alzheimer's disease (AD) according to the International Working Group-2 and National Institute of Aging-Alzheimer's Association criteria, and with cognitive decline. A total of 1394 subjects with mild cognitive impairment from 14 different studies were classified according to these research criteria, based on cognitive pe

Serrated polyps have long been considered to lack malignant potential but accumulating data suggest that these lesions may cause up to one-third of all sporadic colorectal cancer. Serrated polyps are classified into three subtypes, including sessile serrated adenomas/polyps (SSA/Ps), traditional serrated adenomas (TSAs), and hyperplastic polyps (HPs). SSA/P and TSA harbour malignant potential but

Pancreatic cancer is characterized by a dense stromal response. The stroma includes a heterogeneous mass of cells, including pancreatic stellate cells, fibroblasts, immune cells and nerve cells, as well as extracellular matrix proteins, cytokines and growth factors, which interact with the tumor cells. Previous research has indicated that stromal elements contribute to tumor growth and aggressiven

This international task force report updates general considerations for bronchial challenge testing and the performance of the methacholine challenge test. There are notable changes from prior recommendations in order to accommodate newer delivery devices. Rather than basing the test result upon a methacholine concentration (provocative concentration (PC20) causing a 20% fall in forced expiratory

Pancreatic ductal adenocarcinoma (PDAC) prognosis remains very poor and has only marginally improved during the last decades. Epigenetic alterations have been the focus of many recent studies and offer valuable options for PDAC detection, prognosis and treatment. DNA methylation, histone modifications and microRNA (miR) level changes can be used as biomarkers. These alterations occur early in carc

Background Childhood aggressive antisocial behavior (CD) is one of the strongest predictors of mental health problems and criminal behavior in adulthood. The aims of this study were to describe personality profiles in children with CD, and to determine the strength of association between defined neurodevelopmental symptoms, dimensions of character maturity and CD. Methods A sample of 1886 children

Background: Anxiety has been suggested to increase among young individuals, but previous studies on longitudinal trends are inconclusive. The aim of this study was to analyze longitudinally, the changes over time of prevalence of self-reported anxiety in the Swedish population between 1980/1981 and 2004/2005, in different birth cohorts and age groups. Methods: A random sample of non-institutionali

Background: Prostate cancer is the second most frequent cancer among males worldwide, and most patients with metastatic disease eventually develop therapy-resistant disease. Recent research has suggested the existence of cancer stem-like cells, and that such cells are behind the therapy resistance and progression. Methods: Here, we have taken advantage of the relatively quiescent nature of stem ce

Using a parsimonious, analytically tractable dynamic model, we are able to explain up to 100 years of the available data on the dynamics of top-wealth shares for several countries. We build a micro-founded model of heterogeneous agents in which - in addition to stochastic returns on investment - individuals disagree marginally on their expectations of future returns and thus hold different asset p
