Characterization of Drosophila Nidogen/entactin reveals roles in basement membrane stability, barrier function and nervous system patterning

Basement membranes (BMs) are specialized layers of extracellular matrix (ECM) mainly composed of Laminin, type IV Collagen, Perlecan and Nidogen/entactin (NDG). Recent in vivo studies challenged the initially proposed role of NDG as a major ECM linker molecule by revealing dispensability for viability and BM formation. Here, we report the characterization of the single Ndg gene in Drosophila. Embr

Titanium granules pre-treated with hydrogen peroxide inhibit growth of bacteria associated with post-operative infections in spine surgery

Purpose: Post-operative infections are relatively common after posterior spine surgery, and there are several observations reflecting different infection complications related to various metals implanted. Here, we selected an array of different bacterial species that are often found in infections associated with orthopaedic implants and tested for inhibition by hydrogen peroxide-treated titanium (

Risk thresholds for alcohol consumption : combined analysis of individual-participant data for 599 912 current drinkers in 83 prospective studies

Background: Low-risk limits recommended for alcohol consumption vary substantially across different national guidelines. To define thresholds associated with lowest risk for all-cause mortality and cardiovascular disease, we studied individual-participant data from 599 912 current drinkers without previous cardiovascular disease. Methods: We did a combined analysis of individual-participant data f

Five-Second Squeeze Testing in 333 Professional and Semiprofessional Male Ice Hockey Players: How Are Hip and Groin Symptoms, Strength, and Sporting Function Related?

Background: Hip and groin problems are just as common in ice hockey as they are in soccer. The 5-second squeeze test (5SST) is a valid indicator of hip- and groin-related sporting function (self-reported function) in soccer and is suggested to be interpreted according to a “traffic light” approach in guiding the early identification and management of affected players. It is currently unknown how t

Classification of Maize in Complex Smallholder Farming Systems Using UAV Imagery

Yield estimates and yield gap analysis are important for identifying poor agricultural productivity. Remote sensing holds great promise for measuring yield and thus determining yield gaps. Farming systems in sub-Saharan Africa (SSA) are commonly characterized by small field size, intercropping, different crop species with similar phenologies, and sometimes high cloud frequency during the growing s

Effect of indigestible residue from foodstuffs on trypsin and pancreatic α‐amylase activity in vitro

Indigestible residues from black beans (B; Phaseolus vulgaris L cv Tacarigua), green beans (G; Phaseolus vulgaris L), carrots (C; Daucus carota L) and rice bran (R; from Oryza saliva L) were prepared by the pepsin/pancreatin method of Hellendoorn et al and their effect on trypsin and pancreatic α‐amylase was evaluated comparing two experimental procedures. When the remaining caseinolytic enzyme ac

Influence of air and nitrogen sparging on flux during ultrafiltration of hemicelluloses extracted from wheat bran

Ultrafiltration can be used to concentrate arabinoxylan isolated from wheat bran. Prefiltration with diatomaceous earth and air sparging during ultrafiltration of the alkaline hemicellulose solution were both found to increase the flux, while nitrogen sparging had no effect. The flux of the untreated solution was 51 L/m2 h, while the flux after prefiltration of the solution with diatomaceous earth

Anti-D (WinRho SD™) treatment of children with chronic autoimmune thrombocytopenic purpura stimulates transient cytokine/chemokine production

Intravenous anti-D is often used in the treatment of autoimmune thrombocytopenic purpura (AITP), but little is known about its mechanisms of action. To investigate anti-D's potential in vivo mechanism(s) of action, a small group (N = 7) of children with chronic AITP was studied. The children initially received either 25 or 50 μg/kg of WinRho-SD in a four-cycle cross-over trial, and peripheral bloo

Comparison of Cu salts and commercial Cu based fungicides on toxicity towards microorganisms in soil

Microbial responses to Cu pollution as a function of Cu sources (Cu salts and commercial Cu fungicides) were assessed in a soil using basal soil respiration, and bacterial and fungal community growth, as endpoints. The soil was amended with different concentrations (0–32 mmol Cu kg−1) of Cu nitrate, Cu sulfate, Bordeaux mixture and 3 types of Cu oxychloride. Cu salts decreased soil pH, while this

Tone restoration in transcribed Kammu: decision-list word sense disambiguation for an unwritten language

The RWAAI (Repository and Workspace for Austroasiatic Intangible heritage) project aims at building a digital archive out of existing legacy data from the austroasiatic language family. One aspect of the project is the preservation of analogue legacy data. In this context, we have at our hands a large number of mostly-phonemic transcriptions of narrative monologues, often with accompanying sound r

Individual and contextual determinants of self-reported poor psychological health: A population-based multilevel analysis in southern Sweden.

Objective: To investigate the influence of contextual and individual factors on self-reported psychological health. Design/setting/participants/measurements: The 2000 public health survey in Scania is a cross-sectional postal questionnaire study with a 59% participation rate. A total of 13,715 persons aged 18-80 answered the questionnaire. A multilevel logistic regression model, with individuals a

Free volume sizes in intercalated polyamide 6/clay nanocomposites

The effect of incorporating modified clay into a polyamide 6 (PA6) matrix, on the free volume cavity sizes and the thermal and viscoelastic properties of the resulting nanocomposite, was studied with positron annihilation lifetime spectroscopy, differential scanning calorimetry and dynamic mechanical analysis. At low concentrations of clay the fraction of PA6 crystals melting close to 212 degrees

Enhancement of poorly edible phytoplankton by allochthonous dissolved organic material: a modelling study

The effect of different input rates of dissolved inorganic (DIN) and organic (DON) nitrogen on a microbial food web was studied with the help of a mathematical model. Three species of phytoplankton were modelled, with trade-off characteristics for maximum per capita growth rate, half-saturation constant and edibility. Bacteria used only DON, while 2 different types of microzooplankton grazed on th

Discrimination of benign from malignant prostatic disease by selective measurements of single chain, intact free prostate specific antigen

Purpose: Free prostate specific antigen (PSA) in serum consists of heterogeneous molecular subforms. Recently we developed an immunoassay for selective measurement of a subfraction of free PSA called intact PSA, which has been shown to be closely associated with prostate cancer. We assessed the ability of serum intact PSA to discriminate between benign and malignant prostatic disease. Materials an

Agrarian plant economy at Uppåkra and the surrounding area : Archaeobotanical studies of an Iron Age regional center

Up until the late nineteenth and early twentieth century, and probably since the introduction of agriculture to Sweden, the social life, culture, traditions, building patterns and material culture would largely have been based on agricultural practices. And yet, in the archaeological record, agricultural aspects of social life remain elusive and little is known about the organization of farming an

What happens to vowels and consonants when we speak faster?

The subjects of this article are Kozhevnikov and Chistovitch's finding regarding the constancy of relative syllable durations and the inconstancy of relative speech sound durations for different rates of speech, and their proposal that vowels are elided because the necessary minimum duration of a consonant consumes all the time that happens to have been assigned to the syllable. The relative cons

Definition of landscape erosion units using a structural classification OASIS of Landsat TM satellite imageries, case study Lebanon.

Soil erosion by water is a major cause of landscape degradation in semi-humid to semi-arid Mediterranean environments. Terrain particularly susceptible to the phenomenon witness a combination of erosive soil, unconsolidated rock type, steep slope, high rainfall intensity, active tectonic movement, rapid land use change and intense human interference. Current erosion models (e.g. USLE, RUSLE) are b

Prognostic impact of circulating tumor cell apoptosis and clusters in serial blood samples from patients with metastatic breast cancer in a prospective observational cohort

Background: Presence of circulating tumor cells (CTCs) is a validated prognostic marker in metastatic breast cancer. Additional prognostic information may be obtained by morphologic characterization of CTCs. We explored whether apoptotic CTCs, CTC clusters and leukocytes attached to CTCs are associated with breast cancer subtype and prognosis at base-line (BL) and in follow-up (FU) blood samples i

Community mobilization and peer education in a HIV-STI prevention program for university students

Popular Abstract in Swedish Det är en viktig uppgift för samhället att förebygga HIV och STI (sexuellt överförbara infektioner) bland ungdomar. Under de första åren av 1990-talet, när denna studie genomfördes, ökade dessa infektioner på ett oroväckande sätt. Detta gällde särskilt klamydiainfektionerna och nästan 25% av studenterna vid Lunds universitet rapporterade att de hade haft en konstaterad Slowing the incidence of HIV and STI among young people requires that they change their sexual behaviours. There is evidence that community-based interventions that target multiple levels of influence can be effective. In community mobilization different segments and sectors of a population are directly involved in problem identification and in the design and implementation of programs. The proces
