We screened 150 olfactory sensilla in single-sensillum recordings to unravel the mechanisms underlying host selection in the spruce bark beetle, Ips typographus (Coleoptera: Curculionidae: Scolytinae). Odor stimuli comprised of pheromone (various bark beetle spp.), host, and non-host compounds elicited strong and selective responses from 106 olfactory receptor neurons (ORNs), 45 of which were tune

We have examined concurrent and prospective validity of an index of self-reported walking (RW) of 307 home-dwelling women aged 75 years and above, of whom 155 in 1 year had in all 308 falls of which 13% resulting in fractures. It consists of five items concerning various aspects of self-reported walking identified by factor analysis. The sum score on this ''RW-index'' correlated moderately ( r = 0

Objective To determine the effect of exercise training on survival in patients with heart failure due to left ventricular systolic dysfunction. Design Collaborative meta-analysis. Inclusion criteria Randomised parallel group controlled trials of exercise training, for at least eight weeks with individual patient data on survival for at least three months. Studies reviewed Nine datasets, totalling

Objective: To study a controversy that has been discussed for more than two decades: whether or not children with autism have abnormalities affecting the cochlear nerve or the auditory pathway in the brain stem and, if so, to describe these abnormalities. Design: A group of 153 children and adolescents with autistic disorder were included in an investigation of auditory brain stem responses (ABR).

Population-based studies on contact allergy to p-phenylenediamine (PPD) are scarce. A cross-sectional study was performed to assess the prevalence of contact allergy to PPD and its risk factors in the general population of 5 European countries. A total of 10,425 subjects were interviewed, and a random sample (n = 2,739) was patch tested to PPD. Overall, 5,286 individuals (50.9%) reported having us

A search for Higgs boson production in association with a W or Z boson, in the H -> WW* decay channel, is performed with a data sample collected with the ATLAS detector at the LHC in proton-proton collisions at centre-of-mass energies root s = 7 TeV and 8TeV, corresponding to integrated luminosities of 4.5 fb(-1) and 20.3 fb(-1), respectively. The W H production mode is studied in two-lepton and t

A common variant (rs4712652) adjacent to the prolactin gene was recently associated with obesity using a genome-wide association study. The aim of this study was to replicate the association between rs4712652 and obesity and further examine if rs4712652 is associated with fat percentage and adiponectin levels in a population based Scandinavian cohort. rs4712652 was genotyped in 4879 participants (

Tomosynthesis (digital tomography) is a recently introduced low-dose alternative to CT in the evaluation of the lungs in patients with cystic fibrosis and pulmonary nodules. Previous studies have reported an adult effective dose of 0.12-0.13 mSv for chest tomosynthesis. The aim of this study was to determine the paediatric effective dose from the dose-area-product. During a 3-y period, 38 children

Background:Sedative and analgesic medications are used in critically ill newborns, but little is known about their effects on electrocortical activity in preterm infants. We hypothesized that morphine might induce prolonged neurodepression, independent of blood pressure, compared with rapid sequence induction/intubation (RSI).Methods:Of 34 infants enrolled into a randomized controlled trial (RCT)

We have evaluated the efficiency of two popular end-point methods to calculate ligand-binding free energies, LIE (linear interaction energy) and MM/GBSA (molecular mechanics with generalized Born surface-area solvation), i.e. the computational effort needed to obtain estimates of a similar precision. As a test case, we use the binding of seven biotin analogues to avidin. The energy terms used by M

The objective was to study ambulatory blood pressure and heart rate variability between day and night in patients with type 1 (insulin-dependent) diabetes mellitus with different degrees of diabetic nephropathy, and to evaluate the influence of autonomic neuropathy and type of antihypertensive treatment. Twenty type 1 diabetic patients with diabetic nephropathy and antihypertensive treatment were

Achilles tendinopathy is common and treatment with eccentric exercises seems promising. We designed a prospective randomized clinical trial to test the hypothesis that eccentric calf muscle exercises reduce pain and improve function in patients with Achilles tendinopathy. Forty-four patients were recruited from primary care (mean age: 45 years; 23 women; 65% active in sports) and randomized to thr

OBJECTIVE: To investigate markers of endothelial activation in muscle biopsies from rheumatoid arthritis (RA) patients with and without extra-articular manifestations (ExRA). PATIENTS AND METHODS: Nine consecutive ExRA patients were compared with nine RA controls without ExRA, matched for age, sex and duration of RA. Muscle biopsies were obtained from the lateral vastus or anterior tibial muscle.

The Siberian Jay (Perisoreus infaustus) lives in resident, territorial family groups outside the breeding season, but does not breed cooperatively. Thereby it offers an opportunity to study the evolution of territorial group living, without confounding effects of reproductive cooperation. During a long-term study in Finland 1974-2000, we observed Siberian Jay group composition in autumn. Using mic

OBJECTIVE: to study the proximal fixation of different aortic stent grafts in comparison to a hand-sewn anastomosis. DESIGN: experimental study. MATERIAL: the infrarenal aorta of 16 human cadavers were exposed, left in situ and transected 3 cm above the aortic bifurcation to mimic an infrarenal aortic neck. Stent grafts were deployed through a sheath 5 cm into the aorta. Ancure, Talent, Vanguard,

In this study healthy never-smoking subjects (n = 18) were recruited from a population study. Bronchoalveolar lavage (BAL), blood lymphocytes and bronchial biopsies, analysed both in the epithelium and lamina propria, were stained for T and B lymphocytes, natural killer (NK) cells and different subpopulations of T lymphocytes. In BAL, significantly higher proportions of T lymphocytes (CD3), T lymp

This study aimed to compare the duration of protection against exercise-induced bronchoconstriction (EIB) after inhalation of formoterol (Oxis) Turbuhaler with that of terbutaline Turbuhaler and placebo Turbuhaler in asthmatic patients treated regularly with formoterol Turbuhaler 9 microg b.i.d. and inhaled steroids. The study. performed at three centres (Goteborg and Lund, Sweden, and Trondheim,
