Mapping the New Molecular Landscape: Social Dimensions of Epigenetics

Epigenetics is the study of changes in gene expression caused by mechanisms other than changes in the DNA itself. The field is rapidly growing and being widely promoted, attracting attention in diverse arenas. These include those of the social sciences, where some researchers have been encouraged by the resonance between imaginaries of development within epigenetics and social theory. Yet, sustain

Plasma assisted combustion: Effects of O3 on large scale turbulent combustion studied with laser diagnostics and Large Eddy Simulations

Abstract In plasma-assisted combustion, electric energy is added to the flame where the electric energy will be transferred to kinetic energy of the free electrons that, in turn, will modify the combustion chemical kinetics. In order to increase the understanding of this complex process, the influence of one of the products of the altered chemical kinetics, ozone (O3), has been isolated and studie

Electrospun carbon nanofibers from polyacrylonitrile blended with activated or graphitized carbonaceous materials for improving anodic bioelectrocatalysis.

The electrospun carbon nanofibers obtained from polyacrylonitrile (PAN) and PAN blends with either activated carbon (PAN-AC) or graphite (PAN-GR) were tested as anodes using Shewanella oneidensis MR-1. Extensive physico-chemical and electrochemical characterization confirmed their formation, their fibrous and porous nature, and their suitability as electrodes. N(2) adsorption measurements revealed

The International Collaboration of Orthopaedic Nursing: advancing nursing through technology

AimTo report on the International Collaboration of Orthopaedic Nursing, a mostly virtual network of orthopaedic nursing organizations across four continents. BackgroundFormed by leaders of three national associations, the collaboration is based on recognition of patient problems and challenges shared by orthopaedic nurses globally. Methods/InitiativesThe Collaboration provides a range of services

Structural insights into aquaporin selectivity and regulation.

Aquaporins have emerged as one of the structurally best-characterized membrane protein families, with fourteen different structures available from a diverse range of organisms. While all aquaporins share the same fold and passive mechanism for water permeation, structural details allow for differences in selectivity and modes of regulation. These details are now the emphasis of aquaporin structura

Development of a novel combined fluorescence and reflectance spectroscopy system for guiding high-grade glioma resections _ Confirmation of capability in lab experiments

Total resection of glioblastoma multiform (GBM), the most common and aggressive malignant brain tumor, is challenging among other things due to difficulty in intraoperative discrimination between normal and residual tumor cells. This project demonstrates the potential of a system based on a combination of autofluorescence and diffuse reflectance spectroscopy to be useful as an intraoperative guidi

Improving the Lot of the Farmer: Development Challenges in Timor-Leste during the Second Decade of Independence

Large segments of the rural Timorese population survive on subsistence farming characterized by simple production methods and low output. Broad-based improvements in Timorese living standards require increased agricultural output. This article discusses what determines agricultural development in Timor-Leste and how such development can be achieved. The main causes of low agricultural output is fo

LRIG1 and the liar paradox in prostate cancer: a study of the expression and clinical significance of LRIG1 in prostate cancer

The course of prostate cancer varies greatly, and additional prognostic markers are needed. Leucine-rich repeats and immunoglobulin-like domains protein 1 (LRIG1) is an endogenous inhibitor of growth factor signaling and a proposed tumor suppressor. Publicly available gene expression datasets indicate that LRIG1 may be overexpressed in prostate cancer. In our study, the expression of LRIG1 protein

Risk for Life-Threatening Cardiac Events in Patients With Genotype-Confirmed Long-QT Syndrome and Normal-Range Corrected QT Intervals

Objectives This study was designed to assess the clinical course and to identify risk factors for life-threatening events in patients with long-QT syndrome (LQTS) with normal corrected QT (QTc) intervals. Background Current data regarding the outcome of patients with concealed LQTS are limited. Methods Clinical and genetic risk factors for aborted cardiac arrest (ACA) or sudden cardiac death (SCD)

Inhibition of Phosphodiesterase 4 Enhances Clitoral and Vaginal Blood Flow Responses to Dorsal Clitoral Nerve Stimulation or PGE1 in Anesthetized Female Rats.

INTRODUCTION.: Cyclic adenosine 3'5' monophosphate (cAMP) is produced by adenylate cyclase after activation by, e.g., vasoactive intestinal polypeptide or prostaglandin E1 (PGE1). The cAMP-degrading phosphodiesterase 4 (PDE4) is expressed in the vagina and clitoris, but no information is available on the functional role for PDE4-related signals in the female neurovascular genital response. AIM.: T

The relation between speed environment, age and injury outcome for bicyclists struck by a motorized vehicle - a comparison with pedestrians.

This study analyzes (a) the relation between injury severities, the age of the bicyclist and the speed environment at accident locations (mean travel speed of the traffic flow involved in the accident) where a bicyclist was struck by a motorized vehicle and (b) how these relations differ from those for struck pedestrians. Accident data from Sweden for the years 2004-2008 was used to identify accid

The association between metacarpal ratio, radiographic hand and knee osteoarthritis and its progression after meniscectomy

Objective: To examine whether the ratio of the second and fourth metacarpal bone length (MC2:MC4) in subjects with prior meniscectomy of the knee is associated with radiographic hand and knee osteoarthritis (OA) and its progression. Design: We assessed 219 subjects (175 men and 44 women) twice with a follow-up time ranging from 4 to 10 years. Participants had all undergone prior meniscectomy. The

Classification, epidemiology and clinical subgrouping of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis.

It is now 25 years since the first European studies on vasculitis-the anti-neutrophil cytoplasmic antibody (ANCA) standardization project. Over that period of time, there have been major developments in the classification of the vasculitides, which has permitted the conduct of high-quality epidemiology studies. Studying the epidemiology of rare diseases such as the ANCA-associated vasculitides (AA

Immunochemical Staining of MT2-MMP Correlates Positively to Angiogenesis of Human Esophageal Cancer

Matrix metalloproteinases (MMPs) play an important role in the pathological processes of degradation of extracellular matrix and destruction of basement membrane, which leads to tumor invasion and metastasis. In the present study, we investigated membrane-type 2 MMP (MT2-MMP) expression pattern in esophageal cancer tissues collected from 103 patients, and explored MT2-MMP expression pattern in cor

The hospital LIMM-based clinical pharmacy service improves the quality of the patient medication process and saves time

Objective: The Lund Integrated Medicines Management (LIMM) model improves the patient medication process and reduces primary care contact and rehospitalisation. The objective was to evaluate the quality of medication management activities and the time spent on these activities using the LIMM model in hospital and primary care. Methods: Questionnaires were distributed to physicians and nurses in h
