I denna rapport redovisas populationstrender för 228 svenska fågelarter för olika långa tidsperioder. Vi visar också korttidstrender för 12 arter av större däggdjur. Fåglarna har räknats höst, vinter, vår och sommar enligt strikt standardiserade metoder. Sommar- respektive vinterpunktrutter har räknats sedan 1975, i huvudsak i södra Sverige. Standardrutterna räknas också på sommaren (sedan1996) meWe present the results of the Swedish Bird Survey, run by the Department of Biology, Lund University, as a part of the National Monitoring Programme of the Swedish Environmental Protection Agency. The results for 2020 include data from: 564 winter point counts in 2019/2020 (45th winter), of which 274 were carried out during the Christmas/New Year count, 210 summer point count routes (46th year) an

Human complex-forming glycoprotein, heterogeneous in charge (protein HC) has previously been isolated from urine and immunochemically shown to be present in low and high molecular weight forms in blood plasma (Tejler, L., and Grubb, A. O. (1976) Biochim. Biophys. Acta 439, 82-94). In the present work, the major low and high molecular weight forms of the protein were isolated from plasma by immunos

Background: In patients with chronic obstructive pulmonary disease (COPD), the relationship between short-term bronchodilator reversibility and longer-term response to bronchodilators is unclear. Here, we investigated whether the efficacy of long-acting bronchodilators is associated with reversibility of airflow limitation in patients with COPD with a low exacerbation risk not receiving inhaled co

BACKGROUND: Atrioventricular plane displacement (AVPD) reflects longitudinal left ventricular (LV) systolic function, and wall thickening (WT) regional radial LV function. The temporal evolution of these measures after STEMI with CMR has not been evaluated. We aimed to investigate how AVPD and WT are affected globally and regionally from the sub-acute to the chronic phase after ST-elevation myocar

Background: The frequent emergence of the re-positive patients with COVID-19 is a potential threat worldwide. This study aimed to describe data from admission to follow-up for patients with COVID-19 and analyze the possible causes for re-positive nucleic acid tests to provide more scientific basis for reducing the numbers of re-positive patients after discharge. Methods: We retrospectively recorde

We studied avian development in 49 to 153 species of temperate and tropical New World passerine birds to determine how growth rates, and incubation and nestling periods, varied in relation to other life-history traits. We collected growth data and generated unbiased mass and tarsus growth rate estimates (mass n = 92 species, tarsus n = 49 species), and measured incubation period (n = 151) and nest

OBJECTIVE: To evaluate the outcomes after fenestrated endovascular aortic repair (f-EVAR) in a tertiary European referral center. METHODS: All patients treated with commercially available custom-made f-EVAR between September 2002 and June 2007 were prospectively enrolled in a computerized database including co-morbidities and aneurysm morphology. Patients were retrospectively analyzed. Follow-up c

OBJECTIVES: To evaluate the prophylactic efficacy of the human papillomavirus (HPV) quadrivalent vaccine in preventing low grade cervical, vulvar, and vaginal intraepithelial neoplasias and anogenital warts (condyloma acuminata). DESIGN: Data from two international, double blind, placebo controlled, randomised efficacy trials of quadrivalent HPV vaccine (protocol 013 (FUTURE I) and protocol 015 (F

Popular Abstract in Swedish Esofagektomi (kirurgiskt avlägsnande av matstrupen) är ett omfattande ingrepp som främst utförs pga cancer, men som även utförs vid vissa godartade sjukdomar. Matstrupen sträcker sig från svalget, via bakre delen av bröstkorgen ned till övre delen av buken. Det anatomiska läget gör att man ur kirurgisk synpunkt oftast måste avlägsna matstrupen via en kombination av inciIn a prospective randomised study following oesophagectomy and gastric tube reconstruction patients with hand-sutured neck anastomoses were compared with patients with circular stapled chest anastomoses. The two groups had equal rates of anastomotic or conduit leaks of 7.3 % (3/41) and 7.1 % (3/42) and of benign anastomotic strictures of 19.5 % (8/41) and 28.6 % (12/42). Another prospective random

The Baltic Sea is one of many aquatic ecosystems that show long-term declines in dissolved silicate (DSi) concentrations due to anthropogenic alteration of the biogeochemical Si cycle. Reductions in DSi in aquatic ecosystems have been coupled to hydrological regulation reducing inputs, but also with eutrophication, although the relative significance of both processes remains unknown for the observ

Intermittent Parathyroid Hormone (PTH)((1-34)) has an established place in osteoporosis treatment, but also shows promising results in models of bone repair. Previous studies have been dominated by closed fracture models, where union is certain. One of the major clinical needs for anabolic therapies is the treatment of open and high energy fractures at risk of non-union. In the present study we th

Background: Podocalyxin-like 1 (PODXL) is a cell-adhesion glycoprotein and stem cell marker that has been associated with an aggressive tumour phenotype and adverse outcome in several cancer types. We recently demonstrated that overexpression of PODXL is an independent factor of poor prognosis in colorectal cancer (CRC). The aim of this study was to validate these results in two additional indepen

The complement system, a part of the innate immune system with several links to the adaptive immune system, plays an important role in the pathogenesis of many diseases. The purpose of this thesis was to document and clarify some of these mechanisms. The thesis is based on four papers (I-IV). (I and II) Autoantibodies to the C3 cleaving enzyme complex of the alternative pathway, C3 nephritic facto

Objective: Transcatheter valve-in-valve implantation has emerged as an option, in addition to reoperative surgical aortic valve replacement, to treat failed biologic heart valve substitutes. However, the clinical experience with this approach is still limited. We report the comprehensive experience of transcatheter valve-in-valve implantation in the Nordic countries from May 2008 to January 2012.

Background: The aim of this study was to examine in elderly men a relationship between depressive symptoms, peripheral vascular disease and cerebral blood flow (CBF). Methods: Population-based cohort study started with an examination of 809 men at age 55, followed by the first (age 68ys) and second follow up (age 82ys). 128 survivors were examined at age 82 with Tc-99m-HMPAO-SPECT to estimate CBF,

Popular Abstract in Swedish Kraven på bränslesnåla och rena motorer har ökat under de senaste åren. Det började med att priset på olja steg kraftigt i början av 2000-talet. Kraven växte sedan ytterligare i kölvattnet av debatten kring växthuseffekten där koldioxid, en av de dominerande produkterna vid förbränning, spelar huvudrollen. Med tanke på att sänkt bränsleförbrukning rör både ekonomiska ocIn the last decade diesel combustion has developed in a new direction. Research has been carried out trying to prolong the ignition delay and enhance fuel/air premixing to avoid diffusion combustion as well as lowering the combustion temperature through use of EGR. One of these new combustion concepts is Partially Premixed Combustion (PPC). PPC is aimed to provide combustion with low smoke and NOx

Background The two main functional goals of postural control are postural stability (balance) and postural orientation. Postural orientation is the ability to maintain alignment between body segments and the environment during a static or dynamic activity. Nae et al. have evaluated the measurement properties of a clinical test battery for assessing postural orientation errors (POEs) in patients wi

Climate change will alter the hydrological cycle in the 21st century with implications for the water balance and water quality. As characteristics of the landscape may vary significantly between nearby locations, hydrological models need to be able to delineate responses attributed to specific landscape characteristics, to estimate their responses to altered climatic drivers. Small streams are the

In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. Planar Lase

Heterologous overexpression of proteins signifies that the encoding gene of a protein in one organism is expressed in another host organism that normally does not have that gene in its genome. In basic biochemical research, this is an important method for studying various protein functions such as activity and interactions in biological processes, as well as obtaining sufficient amounts to determi
