Henk P van der Jeugd, Anne Kwak
The resident Dutch Northern Delta barnacle geese Branta leucopsis population expanded steadily since birds first bred in 1982, increasing agricultural conflict. Derogation shooting has been used since 2005 to scare geese from sensitive crops and to reduce population size. Numbers almost doubled to ca. 28 000 individuals during 2007-2014, despite annual removal of 15-25% of geese and adult and juvenile survival rates of 79 and 67% (cf. natural survival of 96% for both age classes). Simple population modelling, using estimated annual survival values and fixed fecundity, predicted a moderate increase to 21 500 individuals in 2014...

Cardiac fibrosis (CF), a repairing process following myocardial infarction (MI), is characterized by abnormal proliferation of cardiac fibroblasts and excessive deposition of extracellular matrix (ECM) resulting in inevitable resultant heart failure. TGF-β (transforming growth factor-β)/ALK5 (Activin receptor-like kinase 5)/Smad2/3/4 pathways have been reported to be involved in the process. Recent studies have implicated both activin and its specific downstream component ALK4 in stimulating fibrosis in non-cardiac organs...

Rhinovirus (RV) is a common respiratory viral infection linked to worsening of chronic respiratory diseases including cystic fibrosis (CF) and asthma. RV was tested by RT-PCR in samples (n = 465) collected from the upper (nasal swab, oropharyngeal suction and sputum) and lower (bronchoalveolar washings) respiratory tract of 110 children with CF. Air samples (n = 52) collected from the operating theatres and outpatient clinics were tested for RV. RV was found in 43% of children <5 years suffering an exacerbation, and 12% of older children (5-17 years)...

Cystic fibrosis-related diabetes (CFRD) is the most common co-morbidity associated with cystic fibrosis (CF) and correlates with increased rates of lung function decline. Since glucose is a nutrient present in the airways of patients with bacterial airway infections and since insulin controls glucose metabolism, the effect of insulin on CF airway epithelia was investigated to determine the role of insulin receptors and glucose transport in regulating glucose availability in the airway. The response to insulin by human airway epithelial cells was characterized by qPCR, immunoblot, immunofluorescence, and glucose uptake assays...

5-fluorouracil (5-FU) and cisplatin (CDDP) are common chemotherapy drugs used in the treatment of patients with advanced esophageal cancer. We investigated the efficacy of adding a continuous infusion of a large dose of a common adjuvant, citrovorumfactor (CF), to the traditional 5-FU/wCDDP regimen. 50 patients with advanced esophageal cancer were treated with a continuous infusion of CF, 5-FU, and CDDP, and the short-term effects, adverse reactions, and survival periods after treatment were analyzed. Overall, the treatment was effective in 58% of patients, and the therapeutic effects of the first-line of chemotherapy were significantly better than the second-line (u = 4...

Various fungi have the ability to colonize surfaces and to form biofilms. Fungal biofilm-associated infections are frequently refractory to targeted treatment because of resistance to antifungal drugs. One fungus that frequently colonises the respiratory tract of cystic fibrosis (CF) patients is the opportunistic black yeast-like fungus Exophiala dermatitidis. We investigated the biofilm-forming ability of E. dermatitidis and its susceptibility to various antiinfective agents and natural compounds. We tested 58 E...

Solution-processable small molecule photovoltaics based on the novel molecular donor, benzodithiophene terthiophene rhodanine (BTR), recently have shown maximum power conversion efficiencies above 8 % for active layer thicknesses up to 400 nm, using post process solvent vapor annealing (SVA) with tetrahydrofuran (THF). Here we report an in-situ study on the morphology evolution during SVA using the moderate solvent THF and the good solvent chloroform (CF). The combination of real-time grazing incidence X-ray diffraction (GIXD) and grazing incidence small angle X-ray scattering (GISAXS) allows us to draw a complete picture of the evolution of crystallinity and phase purity during post process annealing...

Cystic fibrosis (CF) is a life-limiting disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR). This defective chloride channel, present in different organ systems such as respiratory system, gastrointestinal tract, reproductive system and sweat glands, disturbs the ion and water transport over the membranes leading to the well known CF symptoms. CF has outgrown paediatric care, as half of CF patients are currently adults. The CF gastrointestinal tract has its own particularities...

INTRODUCTION: Cystic Fibrosis (CF) is an autosomal recessive disorder and the incidence of this disease is undermined in Northern India. The distinguishable salty character of the sweat belonging to individuals suffering from CF makes sweat chloride estimation essential for diagnosis of CF disease. AIM: The aim of this prospective study was to elucidate the relationship of sweat chloride levels with clinical features and pattern of CF. MATERIALS AND METHODS: A total of 182 patients, with clinical features of CF were included in this study for quantitative measurement of sweat chloride...

OBJECTIVES: Faecal calprotectin (FC) is a marker of inflammation in the intestinal tract. We assessed FC levels longitudinally in patients with cystic fibrosis (CF) and evaluated the relation between FC results and relevant markers of disease. METHODS: Calprotectin was measured in faecal samples starting in 2003 and values were stored in the centre's patient database. In this retrospective analysis we searched for associations of FC concentrations with disease severity and progression...

Grazing and burrowing organisms usually homogenise microalgal mats that form on benthic sediments of many aquatic ecosystems. In the absence of this disruption, microalgal mats can accrete laminated deposits (stromatolites). Stromatolites are rare in modern coastal ecosystems, but persist at locations where metazoans are largely excluded. This study aimed to assess the trophic structure at stromatolite locations where metazoans co-occur, to determine the grazing influence exerted by the metazoans on the stromatolite-forming microalgae (cyanobacteria and diatoms)...

BACKGROUND: The Major Histocompatibility Complex (MHC) is a key component of the adaptive immune system of all vertebrates and consists of the most polymorphic genes known to date. Due to this complexity, however, MHC remains to be characterized in many species including any Neotropical cichlid fish. Neotropical crater lake cichlids are ideal models to study evolutionary processes as they display one of the most convincing examples of sympatric and repeated parallel radiation events within and among isolated crater lakes...

Chronic inflammation that progressively disrupts the lung tissue is a hallmark of Cystic Fibrosis (CF). In mice, vardenafil, an inhibitor of phosphodiesterase type 5 (PDE5), restores transepithelial ion transport and corrects mislocalization of the most common CF mutation, F508del-CFTR. It also reduces lung pro-inflammatory responses in mice and in patients with CF. To test the hypothesis that macrophages are target effector cells of the immunomodulatory effect of vardenafil, we isolated lung macrophages from mice homozygous for the F508del mutation or invalidated for the cftr gene and from their corresponding wild-type littermates...
