Within the next 30 years, two thirds of the human population will live in a city. This growing urban population requires a major shift in the way we produce and distribute food, since conventional agriculture practices are responsible for climate change, biodiversity losses, pollution of waterways, soil degradation, etc. Urban and peri-urban agriculture and forestry represent one of the strategies

Solar shading devices can significantly reduce cooling loads, improve thermal comfort and reduce potential glare problems in commercial buildings. However, measured data or tools to facilitate a comparison among various shading devices have previously not been available to designers. The Solar Shading Project at Lund University was initiated in 1997 to increase the knowledge on shading devices. Th

This paper describes the methods used in the International Cancer Benchmarking Partnership Module 4 Survey (ICBPM4) which examines time intervals and routes to cancer diagnosis in 10 jurisdictions. We present the study design with defining and measuring time intervals, identifying patients with cancer, questionnaire development, data management and analyses. Design and setting: Recruitment of part

Objectives To assess how suitable current chronic obstructive pulmonary disease (COPD) cost-effectiveness models are to evaluate personalized treatment options for COPD by exploring the type of heterogeneity included in current models and by validating outcomes for subgroups of patients. Methods A consortium of COPD modeling groups completed three tasks. First, they reported all patient characteri

Abstract– Neural grafting has over the last decade emerged as a possible tool for the substitution of damaged neurons in the central nervous system and for the promotion of symptomatic recovery after brain damage. Transplantation studies in the 6‐hydroxydopamine lesion rat model of Parkinson's disease were initiated in the late seventies. The first studies were based on the neuronal replacement pa

In our homes we enjoy daylight reaching the rooms through the windows, and artificial lighting when there is not enough daylight available. Electrical lighting has been used in Western homes since the late 1910s. We have experienced the technical development from warm incandescent light bulbs to energy-efficient light emitting diods (LED). In Sweden we lack daylight in winter and have a lot of day

Objective: To investigate the association between occupation and risk for sick leave or disability pension due to knee or hip osteoarthritis (OA) from a sex perspective. Methods: We conducted a population-based study including residents ages 40–70 years in the Skåne region, Sweden (2007) and working in the included job sectors (n = 165,179). We retrieved data on cause-specific sick leave and disab

OBJECTIVES: Our aim was to assess the reliability of nailfold capillary assessment in terms of image evaluability, image severity grade ('normal', 'early', 'active', 'late'), capillary density, capillary (apex) width, and presence of giant capillaries, and also to gain further insight into differences in these parameters between patients with systemic sclerosis (SSc), patients with primary Raynaud

X-ray absorption spectroscopy (XAS) includes well-established methods to study the local structure around the absorbing element - extended X-ray absorption fine structure (EXAFS), and the effective oxidation number or to quantitatively determine the speciation of an element in a complex matrix - X-ray absorption near-edge structure (XANES). The increased brilliance and intensities available at the

Substrate pH has been shown to be important for bryophyte distribution, although bryophytes are believed to obtain more or less all of their nutrients from rain water and deposition of airborn dust. In order to better understand bryophyte-pH relations we investigated pH ranges of bryophytes and bryophyte richness at different pH in southern Sweden. In addition, species turnover and critical pH val

Background: In many parts of the world, roadsides are regularly managed for traffic-safety reasons. Hence, there are similarities between roadsides and certain other managed habitats, such as wooded pastures and mown or grazed grasslands. In contrast to roadsides, the latter habitats have declined rapidly in Europe during the last century, and today only a fraction of their former extent remains.

Objectives: To compare the 1-year, 2-year and 5-year incidences of acute coronary syndrome (ACS) in patients with rheumatoid arthritis (RA) starting any of the biologic disease-modifying antirheumatic drugs (bDMARDs) currently available in clinical practice and to anchor these results with a general population comparator. Methods: Observational cohort study, with patients from Denmark, Finland, No

Aims To explore the prevalence and incidence of paediatric implantable cardioverter-defibrillator (ICD) patients in Sweden and identify risk factors associated with appropriate shocks and adverse events. Methods and results We performed a nationwide, retrospective cohort study of ICD use in paediatric patients (<19 years) between 1995 and 2017; 120 patients underwent ICD implantation at median age

D-dimer has been proven to be an excellent rule-out marker for acute type A aortic dissection (ATAAD) with a sensitivity exceeding 95% while specificity remains low. We hypothesized that the addition of fibrinogen, which is decreased in ATAAD patients due to consumption coagulopathy, would increase predictive ability. This was an exploratory, retrospective, single-region, observational study compa

Background: Bile leakage is a severe complication after cholecystectomy and is associated with an increased risk of morbidity and mortality. The aim of this study was to evaluate the incidence of bile leakage post-cholecystectomy and to identify potential risk factors and their association with changes in the incidence of bile leakage over time. Methods: Demographic and perioperative data of all p

Stora och gamla ekar – framtiden för eklandskapets arter Stora och gamla ekar spelar en viktig roll för den biologiska mångfalden. När en ek åldras utvecklar den olika stamstrukturer, till exempel grov bark, döda grenar, blottad ved och håligheter fyllda med mulm, det vill säga en ansamling av nedbrutet organiskt material. Dessa strukturer skapar livsmiljöer för en stor mängd arter, bland annat iLarge and old trees provide important habitat structures and support a high diversity of species. Habitat continuity and landscape connectivity is crucial for species associated with oaks. Fragmentation, agriculture intensification and changed forest management has caused a reduction of old and large oaks, which threatens the long-term persistence of oak associated species by reducing habitat cont

Studying the full universe of nearly 390,000 French patents filed between 1791 and 1900, I show that the nineteenth-century gender patenting gap arose less at the patent office than through unequal access to practical knowledge, collaborators, and time across the life course. I identify 4,165 women inventors using gender-specific honorifics, classify patents with machine learning, reconstruct the

Recently, associations of several common genetic variants with height have been reported in different populations. We attempted to identify further variants associated with adult height in a self-contained population (the Sorbs in Eastern Germany) as discovery set. We performed a genome wide association study (GWAS) (similar to 390 000 genetic polymorphisms, Affymetrix gene arrays) on adult height

The expression of platelet-derived growth factor (PDGF) receptors in porcine uterus and human skin in situ, was compared with that of cultured primary cells isolated from the same tissues. PDGF receptor expression was examined by monoclonal antibodies specific for the B type PDGF receptor and by RNA/RNA in situ hybridization with a probe constructed from a cDNA clone encoding the B type PDGF recep

Mycorrhizal symbioses -- the union of roots and soil fungi -- are universal in terrestrial ecosystems and may have been fundamental to land colonization by plants1,2. Boreal, temperate, and montane forests all depend upon ectomycorrhizae1. Identification of the primary factors that regulate symbiotic development and metabolic activity will therefore open the door to understanding the role of 2 ect
