Quantitative proteomics reveals protein-protein interactions with fibroblast growth factor 12 as a component of the voltage-gated sodium channel 1.2 (nav1.2) macromolecular complex in Mammalian brain

Voltage-gated sodium channels (Nav1.1-Nav1.9) are responsible for the initiation and propagation of action potentials in neurons, controlling firing patterns, synaptic transmission and plasticity of the brain circuit. Yet, it is the protein-protein interactions of the macromolecular complex that exert diverse modulatory actions on the channel, dictating its ultimate functional outcome. Despite the

Fire testing of aerosols and propane bottles

Aerosol-And propane bottles for consumers, including hairspray, lubricants, etc. were tested for exposure from fire. The tested bottles had a volume between 15- 400 ml of product mixed with propane and bottles with propane only containing 0.35, 0.45, 5 and 6 kg of propane. The aerosol-And propane bottles were exposed to a heptane pool fire, corresponding to properties of common available flammable

A large eddy simulation study of bluff body flame dynamics approaching blow-off

The mechanisms leading to blowoff were investigated numerically by analyzing bluff body stabilized flame at two conditions: a condition far from blowoff to a condition just prior to blowoff. Large eddy simulations have been used to capture the time dependent, three-dimensional evolution of the field. The results were first validated to available experimental data, showing very good agreement for t

Surgical reconstruction of ruptured anterior cruciate ligament prolongs trauma-induced increase of inflammatory cytokines in synovial fluid : An exploratory analysis in the KANON trial

Objective: Prospectively monitor how treatment of acutely ruptured anterior cruciate ligament (ACL) affects biomarkers of inflammation and proteolytic degradation over 5 years. Design: We studied 119 subjects with acute ACL injury from the randomized controlled knee anterior cruciate ligament, non-surgical versus surgical treatment (KANON)-trial (Clinical trial ISRCTN 84752559) who had synovial fl

Elimination of Lateral Resistance and Current Crowding in Large-Area LEDs by Composition Grading and Diffusion-Driven Charge Transport

Gallium nitride based light-emitting diodes (LEDs) are presently fundamentally transforming the lighting industry, but limitations in the materials and fabrication methods of LEDs introduce substantial challenges to their future development. Among the remaining key bottlenecks of GaN LEDs are the resistive losses and current crowding that strongly increase the heat generation at high powers. In th

CAG repeat number is not inversely associated with androgen receptor activity in vitro.

A negative linear association between androgen receptor (AR) function and the CAG repeat numbers is generally assumed. However, in vivo data concerning the association between CAG number and androgenic effects have been conflicting. Since former in vitro studies mostly have been based on extreme CAG lengths and reporter-systems containing viral promoters, the objective of this study was to investi

The time aspect of bioenergy - Climate impacts of solid biofuels due to biogenic carbon dynamics

The climate impacts from bioenergy involve an important time aspect. Using forest residues for energy may result in high initial emissions, but net emissions are reduced over time since, if the residues were left on the ground, they would decompose and release CO2 to the atmosphere. This article investigates the climate impacts from bioenergy with special focus on the time aspects. More specifical

Cost-effectiveness of etanercept treatment in early active rheumatoid arthritis followed by dose adjustment.

Objectives: To explore the cost-effectiveness of early biologic treatment, followed by dose-reduction in the case of remission, of active rheumatoid arthritis (RA), compared with standard treatment with methotrexate (MTX) in Sweden.Methods: Effectiveness (function, disease activity, erosions) in early RA for both alternatives was taken from a clinical trial comparing etanercept (ETA) combined with

The risk of contralateral breast cancer in daughters of women with and without breast cancer.

We aimed to estimate the 15-year and lifetime risks of contralateral breast cancer in breast cancer patients according to the age of diagnosis of the first cancer and the history of breast cancer in the mother. The risks of contralateral breast cancer were estimated for all 78,775 breast cancer patients in the Swedish Family-Cancer Database (age at diagnosis of first breast cancer <70 years). The

A randomized, multicentre, double-blind, parallel-group study to assess the adverse event-related discontinuation rate with celecoxib and diclofenac in elderly patients with osteoarthritis.

Objective: To compare the adverse event (AE)-related discontinuation rate with celecoxib vs. diclofenac when given to reduce joint pain associated with knee or hip osteoarthritis (OA) in elderly patients. Methods: This was a double-blind, randomized, multicentre, parallel-group, 1-year comparison of celecoxib 200 mg once daily and diclofenac 50 mg twice daily in 925 patients with OA aged >/= 60 ye

Effect of auditory evoked potential-guided anaesthesia on consumption of anaesthetics and early postoperative cognitive dysfunction : A randomised controlled trial

Background Post-operative cognitive dysfunction (POCD) after non-cardiac surgery is a well known problem in some categories of patients. This study aims to evaluate the influence of auditory evoked potential (AEP)-guided anaesthesia on the requirement for anaesthetic drugs and their influence on POCD. Methods Four hundred and fifty patients aged between 18 and 92 years scheduled for ophthalmic sur

Evaluation of the Postoperative Quality of Recovery Scale test and re-test in Swedish among healthy volunteers

Introduction Patient outcome measures are required to assess the quality of healthcare. Tools for a patients' self-assessment of quality of recovery, during perioperative care, have been developed during the last decade. The Postoperative Quality of Recovery Scale (PostopQRS) questionnaire is one of the most well-accepted and validated tools available. Here we assess the PostopORS questionnaire in

What Happened to 'Race' in Race Biology? The Swedish State Institute for Race Biology, 1936-1960

The Swedish State Institute for Race Biology (SIRB) was founded in 1921 and immediately became the most important institution for racial science in Sweden. We know a great deal about the history of SIRB until 1935, when right-wing director Herman Lundborg retired and was replaced by the left-wing, anti-fascist Gunnar Dahlberg. In this essay, the later history of SIRB is for the first time examined

Contact Allergy to Fragrance Mix II and Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde : A Retrospective Study by International Contact Dermatitis Research Group

BACKGROUND: Fragrance mix II (FM II) is included in the baseline patch test series recommended by the International Contact Dermatitis Research Group (ICDRG). Hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC) is the most important sensitizer of the 6 fragrance materials included in FM II. Besides being a part of FM II, HICC is also tested separately in the ICDRG baseline series. OBJECTIVES: The

A part of social work and apart from social work: : hospital nurses in hospital discharges of older people in Sweden

The aim of this study was to reveal how hospital nurses handle the process when older people are considering relocation to a residential home after hospitalization. The focus is of special interest as, in Sweden, hospital nurses are employed by a county council without the authority to decide on local municipal care after hospital discharge. Ten nurses from three hospital wards participated in ope

PURPOSE: To calculate the normal tissue complication probability (NTCP) of late radiation effects on the rectum and bladder from repetitive CT scans during fractionated high-dose-rate brachytherapy (HDRB) and external beam radiotherapy (EBRT) of the uterine cervix and compare the NTCP with the clinical frequency of late effects.METHODS AND MATERIALS: Fourteen patients with cancer of the uterine ce

Impingement cooling in a rib-roughened channel with cross-flow

A numerical investigation to determine the velocity and heat transfer characteristics of multiple impinging slot jets in rib-roughened channels in the presence of cross-flow has been carried out. Fluid flow is modeled using an explicit algebraic stress model. A simple eddy diffusivity and a generalized gradient diffusion hypothesis are applied for the modeling of turbulent heat fluxes. The computa

Delayed infusion of GDNF promotes recovery of motor function in the partial lesion model of Parkinson's disease

Here we studied the effects of glial cell line-derived neurotrophic factor (GDNF) in a rat model that represents the symptomatic stages of Parkinson's disease. GDNF was infused starting 2 weeks after an intrastriatal 6-hydroxydopamine (6-OHDA) lesion in order to halt the ongoing degeneration of the nigrostriatal dopaminergic neurons. GDNF or vehicle was infused in the striatum or the lateral ventr

Effect of hip flexion on the measurement of spinal bone mineral density in the Norland Eclipse XR

It is recommended that the hip joints be flexed to 90 degrees during dual-energy X-ray absorptiometry scanning of the lumbar spine in the anteroposterior projection; however, some patients are unable to maintain this position because of the presence of degenerative changes in lower limb joints. This study examines the effect of a lesser degree of hip flexion on the lumbar spine bone mineral densit
