Deuteron and antideuteron production in Au+Au collisions at root s(NN)=200 GeV

The production of deuterons and antideuterons in the transverse momentum range 1.1 < p(T)< 4.3 GeV/c at midrapidity in Au+Au collisions at root s(NN) = 200 GeV has been studied by the PHENIX experiment at RHIC. A coalescence analysis, comparing the deuteron and antideuteron spectra with that of proton and antiproton, has been performed. The coalescence probability is equal for both deuterons and a

Technological Capabilities, Institutions and Firm Productivity: A Multilevel Study

National framework conditions directly affect the productivity of firms, but also moderate returns on their technological efforts. Although this has long been recognised, there is a dearth of quantitative analyses that openly consider this hypothesis. Using a data set of 15 425 manufacturing firms in 32 developing countries, we investigate the impact of national institutions on firms' total factor

How to live with the enemy: understanding tolerance to parasites.

How do we defend ourselves against pathogenic microbes and other parasites infecting us? Research on defence against parasites has traditionally focused on resistance-the ability to prevent infection or limit parasite replication. The genetics, physiology, and evolutionary ecology of such traits are now relatively well understood. During the last few years it has been realized that another, concep

Defect and electrical transport properties of Nb-doped SrTiO3

This study reports the defect and electrical transport properties of Nb-doped SrTiO3, Samples with various A/B-ratios were synthesized by a modified glycine-nitrate combustion process and evaluated as a constituent in a SOFC anode. The phase purity and defect structure of the materials have been analyzed with SEM, XRD, TGA, and XANES. The electrical conductivity of Nb-doped strontium titanate (Sr0

Moraliska räkenskaper - etik och praxis inom biomedicinsk forskning

Artikelns utgångspunkt är att dagens biomedicinska samhälle ger upphov till frågor om teknikens möjligheter och risker. Avstamp tas i Ulrich Becks diskussion om att dessa motpoler föder en reflexiv modernitet. Ambitionen är att undersöka hur detta reflexiva tillstånd försiggår på ett individuellt plan, närmare bestämt inom en yrkesgrupp som bedriver omdebatterad biomedicinsk forskning. Den empiris

Effects of extrapair paternity and sex on nestling growth and condition in the collared flycatcher, Ficedula albicollis

Extrapair fertilizations (EPFs) have been found in most socially monogamous passerine species. EPFs are generally beneficial for males because they increase the number of sired offspring. The benefit accrued by females, however, is less obvious. Maternal benefits may involve fertility insurance, increased genetic variability of the offspring, and improved offspring quality via compatible genes or

Prevention of severe contractures might replace multilevel surgery in cerebral palsy: results of a population-based health care programme and new techniques to reduce spasticity

During the 1990s three new techniques to reduce spasticity and dystonia in children with cerebral palsy (CP) were introduced in southern Sweden: selective dorsal rhizotomy, continuous intrathecal baclofen infusion and botulinum toxin treatment. In 1994 a CID register and a health care programme, aimed to prevent hip dislocation and severe contractures, were initiated in the area. The total populat

This study investigated the role of P fimbriae in colonization of Escherichia coli, host response, and bacterial persistence in humans. Human volunteers were inoculated intravesically with the nonadherent ABU isolate E. coli 83972 and with P fimbriated transformants of the same strain. During the following 24 h all urine samples, and thereafter daily samples, were collected for urine culture, anal

Treatment and prevention of acute bleedings in von Willebrand disease--efficacy and safety of Wilate, a new generation von Willebrand factor/factor VIII concentrate.

For many patients with von Willebrand disease (VWD), the replacement therapy with von Willebrand factor (VWF)/factor VIII (FVIII) concentrates is the treatment of choice. To evaluate clinical efficacy, safety and tolerability of Wilate, an albumin-free VWF/FVIII concentrate with a ratio of the two haemostatic moieties of approximately 1 to 1, a prospective clinical programme has been designed. The

Risk factors and treatment at recurrent stroke onset: Results from the recurrent stroke quality and epidemiology (RESQUE) study

Background: Much effort has been made to study first-ever stroke patients. However, recurrent stroke has not been investigated as extensively. It is unclear which risk factors dominate, and whether adequate secondary prevention has been provided to patients who suffer from recurrent stroke. Also, the different types of recurrent stroke need further evaluation. Methods: The study included patients

Haemophilia B carrier detection by factor IX:C analysis; no impact of the type of mutation or severity of disorder

Haemophilia B, an X-linked recessive bleeding disorder characterized by lack or deficiency of factor IX, has been shown to be caused by any of a variety of DNA abnormalities (partial or total deletions, nonsense or missense mutations). Since in most countries carrier detection is based on factor IX coagulant activity (FIX:C) assay, this study was designed to determine whether carriers' FIX:C value

Hollow fibre-supported liquid membrane extraction and LC-MS/MS detection for the analysis of heterocyclic amines in urine samples

Heterocyclic amines (HCAs) are potent mutagens/carcinogens to which humans are frequently exposed through the consumption of cooked meat and fish food. The effect of normal intake of HCAs and their role in the aetiology of human cancer is unknown. To some extent, limitations of the existing analytical methods in monitoring the low levels of HCAs in biological samples have hindered obtaining conclu

Activated Protein C Protein C Inhibitor Complex in Patients With Abdominal Aortic Aneurysms: Is It Associated With Diameter and Growth Rate?

Increased thrombin activation has been documented in patients with abdominal aortic aneurysm (AAA). APC-PCI complex, a new biological marker of thrombin generation, was measured in a population of 232 patients with AAA relative and a control group and the association between aneurysm size, growth rate and APC-PCI was studied. The patients were divided into cohorts according to the AAA diameter and

Effects of intrapleural mitoxantrone and mepacrine on malignant pleural effusion--a randomised study

30 patients with malignant pleuritis were randomised to be treated, either with intrapleural instillation of mepacrine chloride or with mitoxantrone. The patients were evaluated with chest X-ray and a symptom questionnaire during a follow-up period of 12 weeks. Mitoxantrone levels in the pleural space and plasma were measured at different time points in some of the patients. High concentrations of

Psychometric properties of a Swedish version of the Kansas City Cardiomyopathy Questionnaire in a Chronic Heart Failure population.

BACKGROUND: Valid assessments of health-related Quality of Life (HRQL) are increasingly important in chronic, incurable conditions, such as chronic heart failure (CHF). AIMS: To evaluate the psychometric properties of a Swedish version of the Kansas City Cardiomyopathy Questionnaire (KCCQ) in hospitalized patients with decompensated CHF. METHOD AND RESULTS: The KCCQ and SF-36 were administered to

Highly efficient and versatile anodes for biofuel cells based on cellobiose dehydrogenase from Myriococcum thermophilum

A powerful alternative to glucose oxidase as anode material in implantable biofuel cells is presented: Cellobiose dehydrogenase (CDH) from the ascomycete Myriococcum thermophilum (MtCDH) catalyzes the electrochemical oxidation of glucose, lactose, and cellobiose over a broad pH range. Current densities of more than 1 mA . cm(-2) can be reached when MtCDH is wired to an Os redox polymer in the pres

Particle Emission from High-spin States

The present status of prompt particle emission from high-spin states in the mass A~60 region is shortly summarized. The focus lies on recent results from a GAMMASPHERE experiment, which aimed at the combined in-beam high-resolution spectroscopy of light charged particles and γ rays. More detailed studies of known cases as well as the identification of new cases of discrete prompt proton and α-part
