Among the large variety of pincer complexes, those with carbon-carbon double bonds in the backbone have received little attention. Here, we report the reactions of complex (PC=CP)IrPh (3) and its derivatives with small molecules. Compound 3 readily adds CO to give the 18e adduct (PC=CP)IrPhCO (5a), which upon heating undergoes isomerization into the thermodynamically more stable isomer (PC=CP)IrCO
Background: The prognostic role of the arterial blood gas tension of carbon dioxide (PaCO2) in severe Chronic Obstructive Pulmonary Disease (COPD) remains unknown. The aim of this study was to estimate the association between PaCO2 and mortality in oxygen-dependent COPD. Methods: National prospective study of patients starting long-term oxygen therapy (LTOT) for COPD in Sweden between October 1, 2
Depending upon its organization, movement variability may reflect poor or flexible control of a motor task. We studied adult age-related differences in the structure of postural variability in manual pointing using the uncontrolled manifold (UCM) method. Participants from 2 age groups (younger: 20-30 years; older: 70-80 years; 12 subjects per group) completed a total of 120 pointing trials to 2 di
A detailed understanding of the influence of temperature on soil microbial activity is critical to predict future atmospheric CO2 concentrations and feedbacks to anthropogenic warming. We investigated soils exposed to 3-4 years of continuous 5 degrees C-warming in a field experiment in a temperate forest. We found that an index for the temperature adaptation of the microbial community, T-min for b
Clear cell sarcoma of the kidney (CCSK) is a tumor affecting children with a median age of 3 years at diagnosis. The cell of origin of CCSK is unknown and data on the molecular changes giving rise to CCSK is scarce. This has hindered the identification of positive diagnostic markers and development of molecularly targeted treatment protocols for CCSK. We have characterized a panel of CCSK to gain
A simple mass balance model has been developed to assess the planetary boundary for P supply in relation to use by human society. Phosphorus sources used by humans are from fossil reserves. The model takes into account resource use rate and reserves, consumption, phosphate to food production, environmental degradation, waste and recycling. Various policy scenarios are tested from current end of pi
Acetic acid was investigated as a catalyst in steam pretreatment of corn stover. The purpose was to study ethanol production using either baker's yeast or a genetically modified pentose-fermenting version of Saccharomyces cerevisiae, KE6-12. Biogas production was investigated as an alternative for utilization of xylose. The high levels of acetic acid was found to be toxic using KE6-12. Some pentos
Patients with generalized ANCA-associated small vessel vasculitis (AAV) have a very poor outcome if the ANCA-associated vasculitis is not diagnosed, evaluated and treated properly. The introduction of treatment with immunosuppressive therapy has improved patient survival dramatically but with considerable side effects. Besides, almost 50% of surviving patients experience a relapse of vasculitis. S
Background: Few published data link overweight and obesity with measures of quality of life (QoL) including sexual health in men. Objective: To assess the association of overweight/obesity with impairment of physical and psychological QoL and sexual functions in men. Design and setting: Cross-sectional, multicentre survey of 3369 community-dwelling men aged 40-79 (mean +/- S.D., 60 +/- 11) years r
Older adults prefer to age in place, necessitating a match between person and environment, or person-environment (P-E) fit. In occupational therapy practice, home modifications can support independence, but more knowledge is needed to optimize interventions targeting the housing situation of older adults. In response, this study aimed to explore the accessibility and usability of the home environm
Purpose: The purpose of this systematic review was to summarise the evidence from randomised controlled trials examining the effectiveness of physical therapy compared with care as usual or a wait-list condition on eating pathology and on physiological and psychological parameters in patients with anorexia and bulimia nervosa. Method: EMBASE, PsycINFO, PubMed, Cumulative Index to Nursing and Allie
Climate change is leading to a disproportionately large warming in the high northern latitudes, but the magnitude and sign of the future carbon balance of the Arctic are highly uncertain. Using 40 terrestrial biosphere models for the Alaskan Arctic from four recent model intercomparison projects - NACP (North American Carbon Program) site and regional syntheses, TRENDY (Trends in net land atmosphe
Surgical site infections (SSIs) after dermatologic surgery continue to represent undesirable complications that affect patients in several aspects. The etiology and pathogenesis of SSIs are not completely understood, and as a result, current preventative measures are debatable.
Butyric acid, one of the key products formed when β-glucans are degraded by the microbiota in the colon, has been proposed to be important for colonic health. Glutamine bound to the fibre may have similar effects once it has been liberated from the fibre in the colon. Both β-glucans and glutamine are found in high amounts in malted barley. Lactobacillus rhamnosus together with malt has been shown
Determination of the subsurface geology is very important for the rock quarry industry. This is primarily done by drilling and mapping. However, in Sweden, the bedrock is often completely covered by Quaternary sediments, making the prediction quite difficult. This study shows that electrical resistivity imaging together with induced polarization proved to be very efficient in detecting fracture fr
Power spectrum analysis of heart rate variability (HRV) may provide insight into the mental state of the animal held in restricted specific experimental conditions. Determining inter-beat-interval (IBI) variations is one way to measure changes in autonomic nervous system (ANS) activity in horses. An imbalance between the sympathetic and parasympathetic nervous system can indicate pain or stress, f
Complement convertases are enzymatic complexes that play a central role in sustaining and amplification of the complement cascade. Impairment of complement function directly or indirectly leads to pathologic conditions including higher infection rate, kidney diseases, autoimmune- or neurodegenerative diseases and ischemia-reperfusion injury. An assay for direct measurement of activity of the conve
