Southwest China has been the largest terrestrial carbon sink in China over the past 30 years, but has recently experienced a succession of droughts caused by high precipitation variability, potentially threatening vegetation productivity in the region. Yet, the impact of precipitation anomalies on the vegetation primary productivity is poorly known. We used an asymmetry index (AI) to explore possi
The oxidation reactions of alkanes with hydrogen peroxide and peracids (peracetic acid (PAA) and m-chloroperoxybenzoic acid (mCPBA)) catalysed by two Fe(II) complexes of pentadentate {N5}-donor ligands have been investigated. Kinetic isotope effect experiments and the use of other mechanistic probes have also been performed. While the total yields of oxidized products are similar regardless of oxi
BACKGROUND: Varus osteotomy of the proximal femur (VOPF) is one treatment option to prevent hip dislocation in children with cerebral palsy (CP). It is questioned whether the osteotomy should be performed in the displaced hip only, or if it should be performed bilaterally to prevent later displacement of the contralateral hip. CPUP is a register and healthcare programme for children with CP that w
Extensive areas of old forests have declined all over the temperate regions of Europe mainly due to extensive forestry. This is likely to have negative impact on bats that roost in trees, such as the western barbastelle Barbastella barbastellus. We investigated its selection of summer roosts in a commercially used landscape in southern Sweden. We captured and radio-tracked 14 bats and found 17 occ
The app-based COVID Symptom Study was launched in Sweden in April 2020 to contribute to real-time COVID-19 surveillance. We enrolled 143,531 study participants (≥18 years) who contributed 10.6 million daily symptom reports between April 29, 2020 and February 10, 2021. Here, we include data from 19,161 self-reported PCR tests to create a symptom-based model to estimate the individual probability of
Agarose hydrogels have been extensively used as a phantom material to mimic the mechanical behavior of soft biological tissues, e.g. in studies aimed to analyze needle insertions into the organs producing tissue damage. To better predict the radial stress and damage during needle insertions, this study was aimed to determine the friction coefficient between the material of commercial catheters and
OBJECTIVE: To estimate the incremental costs to public payers for patients with ankylosing spondylitis (AS) of working age compared with reference subjects from the general population. METHODS: We investigated total costs for 3 years (2005-2007) in 116 outpatients under 66 years of age with AS attending rheumatological care in Malmö, Sweden. Mean (SD) age was 46 (11) years and mean (SD) disease du
Summary. Physical activity has been considered as an important factor for bone density and as a factor facilitating prevention of osteoporosis. Bone density has been reported to be reduced in haemophilia. To examine the relation between different aspects of physical activity and bone mineral density (BMD) in patients with severe haemophilia on long-term prophylaxis. The study group consisted of 38
Symptoms or signs of peripheral artery disease (PAD) can be observed in up to 50% of the patients with a diabetic foot ulcer and is a risk factor for poor healing and amputation. In 2012 a multidisciplinary working group of the International Working Group on the Diabetic Foot published a systematic review on the effectiveness of revascularization of the ulcerated foot in patients with diabetes and
Objective. Comparison of surgical results on obese patients undergoing hysterectomy by robot-assisted laparoscopy or laparotomy. Setting. University hospital. Methods. All women (n=114) with a BMI ≥30 kg/m(2) who underwent a simple hysterectomy as the main surgical procedure between November 2005 and November 2009 were identified. Robot-assisted procedures (n=50) were separated into an early (lear
PURPOSE: To prospectively register and report the hand function and occupational performance of patients with proximal interphalangeal joint-pyrocarbon arthroplasty, using both objective tests and subjective outcome instruments. METHODS: From 2004 to 2008, 53 joints in 43 patients were reconstructed with a proximal interphalangeal joint-pyrocarbon prosthesis. The patients underwent a rehabilitatio
BACKGROUND: Retransfusion of the patient's own blood during surgery is used to reduce the need for allogenic blood transfusion. It has however been found that this blood contains lipid particles, which form emboli in different organs if the blood is retransfused on the arterial side. In this study, we tested whether retransfusion of blood containing lipid micro-particles on the venous side in a po
Microchromatographic separations of polar aromatic compounds (pyridine, 4-pyridylmethanol, 4-methoxyphenol, 2-naphthol, catechol, hydroquinone, resorcinol, 2,7-dihydroxynaphthalene) using continuous beds are described. The columns were prepared by a simple one-step in situ polymerization procedure: a solution of acrylic monomers, including the cross-linking agent piperazine diacrylamide, was polym
Patients-Seven patients with Barrett's metaplastic epithelium and oesophageal adenocarcinoma were investigated by means of laser induced fluorescence after low dose intravenous injection (0 . 35 mg/kg bw) of Photofrin (QLT, Vancouver, Canada). Laser induced fluorescence measurements were performed immediately after resection of the oesophagus. Methods-Laser induced fluorescence spectra were record
Socioeconomic shocks can shape future land-use trajectories. Armed conflicts are an extreme form of a socioeconomic shock, but our understanding of how armed conflicts affect land-use change is limited. Our goal was to assess land-use changes related to the 1991–1994 Nagorno-Karabakh conflict between Armenia and Azerbaijan in the Caucasus region. We classified multi-temporal Landsat imagery, mappe
In several large recent observational studies, peripheral arterial disease (PAD) was present in up to 50% of the patients with a diabetic foot ulcer and was an independent risk factor for amputation. The International Working Group on the Diabetic Foot therefore established a multidisciplinary working group to evaluate the effectiveness of revascularization of the ulcerated foot in patients with d
Objective. The aim of this study was to evaluate enterocystometry, voiding pattern and urine leakage of four types of orthotopic bladder substitute. Material and methods. At eight urological departments, 78 consecutive men were studied: 66 with an ileal neobladder [30 Studer pouches (S), 24 Hautmann pouches (H) and 12 T-pouches (T)] and 12 with a right colonic [Goldwasser type (G)] neobladder. Ent
PURPOSE: To determine whether reproductive and hormonal risk factors for breast cancer associate with mammography attendance. METHODS: We linked data from the Malmö Diet and Cancer Study to the Malmö mammography register (Sweden, 1992-2009). We analyzed 11,409 women (age 44-72) who were free of breast cancer at study entry and a total of 69,746 screening invitations. Generalized Estimating Equatio
The separation of one weakly and one strongly binding impurity from a therapeutic protein by ion-exchange chromatography was studied with a mechanistic model. The effect of disturbances in eight potentially critical process parameters on two critical quality attributes was evaluated. It was found that the outgoing concentration of the weakly binding impurity was only affected by the ingoing concen
