Abstract The chloroplast-localized NADPH-dependent thioredoxin reductase (NTRC) has been found to be able to reduce hydrogen peroxide scavenging 2-Cys peroxiredoxins. We show that the Arabidopsis ntrc mutant is perturbed in chlorophyll biosynthesis and accumulate intermediates preceding protochlorophyllide formation. A specific involvement of NTRC during biosynthesis of protochlorophyllide is indi
This article builds on an action research process involving Ugandan smallholder farmers in collaborative experimentation on the use of human urine as a crop fertilizer. The aim is to explore farmers' perceptions and evaluation of the practice as a potential and partial solution to soil productivity problems. Findings show that urine fertilization is valued as a low-cost and low-risk practice contr
Background: Electroencephalography (EEG) is widely used to assess neurological prognosis in patients who are comatose after cardiac arrest, but its value is limited by varying definitions of pathological patterns and by inter-rater variability. The American Clinical Neurophysiology Society (ACNS) has recently proposed a standardized EEG-terminology for critical care to address these limitations. I
We present a paleomagnefic study of 1785 to 1770 Ma composite and mafic intrusions in Smaland, Sweden. A positive inverse baked contact test suggests the primary nature of their magnetization. The palaeomagnetic pole (45.7 degrees N, 182.7 degrees E, A(95)=8.0 degrees) may be regarded as a key pole for Fennoscandia. Available paleomagnetic data suggest that Laurentia and Fennoscandia/Balfica drift
Background: Identifying children with childhood-onset neurodevelopmental problems (NDPs, defined here as autism spectrum disorders [ASDs], attention-deficit/hyperactivity disorder [AD/HD], tic disorders [TDs], learning disorders [LDs] and development coordination disorder), using easily administered screening instruments, is a prerequisite for epidemiological research. Such instruments are also cl
ObjectiveTo investigate the anatomical cure rate and complications related to collagen-coated mesh for cystocele, compared with a conventional anterior colporrhaphy. DesignA randomised controlled study. SettingSix departments of obstetrics and gynaecology in Norway, Sweden, Finland, and Denmark. PopulationWomen aged 55years or older, referred for surgery with a prolapse of the anterior vaginal wal
The ATLAS detector at the Large Hadron Collider is used to search for excited electrons and excited muons in the channel pp -> ll* -> ll gamma, assuming that excited leptons are produced via contact interactions. The analysis is based on 13 fb(-1) of pp collisions at a centre-of-mass energy of 8 TeV. No evidence for excited leptons is found, and a limit is set at the 95% credibility level on the c
The mechanisms of neuronal cell death are still only poorly understood, which has hindered the advancement of therapies for many currently untreatable neurodegenerative diseases. This calls for the development of new methods which reveal critical molecular mechanisms of the celldeath machinery with both high sensitivity and cellular resolution. Using animal models for hereditary neurodegeneration
The past years have seen increasing interest in nonlinear optical microscopic imaging approaches for the investigation of diseases due to the method's unique capabilities of deep tissue penetration, 3D sectioning and molecular contrast. Its application in clinical routine diagnostics, however, is hampered by large and costly equipment requiring trained staff and regular maintenance, hence it has n
Thermo-responsive poly(N-isopropylacrylamide) (polyNIPAm) containing terminal boronic acid was synthesized using atom transfer radical polymerization (ATRP) in combination with Cu(I)-catalyzed alkyne-azide 1,3-dipolar cycloaddition (CuAAC) reaction. Alkyne-terminated polyNIPAm was first synthesized by ATRP using an alkyne-containing initiator. A fluorogenic boronic acid, 3-(2-azido-acetylamino)phe
To meet urgent needs for solving serious worldwide drug-resistance problems, a sensitive label-free capacitive sensor developed in our group was investigated as a tool to be applied in the field of antibiotic resistance genotyping, for instance the detection of ampicillin resistance gene (ampR). Proof-of-concept data demonstrated its detection sensitivity of pico-molar without any signal amplifica
Climate change and disaster pose a serious and growing risk to sustainable urban development planning, with disasters having quadrupled in the last three decades. The extent of the changing climatic conditions, in combination with growing urbanisation, is making both Southern and Northern institutions and associated social security and governance systems increasingly inadequate in dealing with ext
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)
In this retrospective epidemiologic study, we present pneumococcal carriage data from 109 Swedish day care centers over a period of 10 years. Aspects of season, age, personnel and group size were studied. We found a significant seasonal variation in pneumococcal carriage. Group size was a significant risk factor for pneumococcal carriage. Pneumococcal carriage was 4.5 % in personnel.
Sexually selected traits are often condition-dependent and are expected to be affected by genome-wide distributed deleterious mutations and inbreeding. However, sexual selection is a powerful selective force that can counteract inbreeding through purging of deleterious mutations. Inbreeding and purging of the inbreeding load for sexually selected traits has rarely been studied across natural popul
The European Spallation Source (ESS) neutron spallation project currently being designed will be built outside of Lund, Sweden. The ESS design includes three helium cryoplants, providing cryogenic cooling for the proton accelerator superconducting cavities, the target neutron source, and for the ESS instrument suite. In total, the cryoplants consume approximately 7 MW of electrical power, and will
Swedish legislation requires that any owner or user of a building maintain a reasonable level of fire protection measures to ensure the safety of all people located in the building. If a building, in the wake of a fire, in court is determined not to have had a reasonable fire protection, the blame will likewise be assigned to the building owner or user. Using the perspective of risk governance, th
BACKGROUND: /st>This study was undertaken to compare the effects of general anaesthesia (GA) and spinal anaesthesia (SA) on the need for postoperative hospitalization and early postoperative comfort in patients undergoing fast-track total knee arthroplasty (TKA). METHODS: /st>One hundred and twenty subjects were randomly allocated to receive either intrathecal bupivacaine (SA group) or GA with tar
The primary aim of the present study was to investigate if methods derived from environmental psychology can be used to study the qualities of the physical environment of supported housing facilities for persons with psychiatric disabilities. Three units of analysis were selected: the private area, the common indoor area, and the outdoor area. Expert assessments of 110 features of the physical env
