PDGF family function and prognostic value in tumor biology

The development and progression of a tumor depends on the close interaction of malignant cells and the supportive and suppressive tumor microenvironment. Paracrine signaling enables tumor cells to shape the surrounding tissue in order to decrease recognition by the immune system, attract blood vessels to fuel growth, change metabolic programs, and induce wound healing programs. In this study, we i

The experiences of pre- and in-hospital care in patients with hip fractures : A study based on Critical incidents

Background: Hip fractures are described to have a significant impact on patients' well-being and different fast-track concepts could result in a reduction of the patient's psychological and emotional reactions before pre- and intrahospital care. Aims and objectives: This study aimed to elucidate perceived situations of significance experienced by patients with hip fracture during the prehospital-

“We are service people, and we stay until the job is done” : enactments of professionalism in restaurants

In response to calls for increased professionalism in the restaurant industry, this paper aims to show how it is constituted in the daily practices in the industry, and to clarify ideas of professionalism held by the practitioners in the industry. Micro practices of daily activities performed by restaurant practitioners were identified in 13 small restaurants: 8 in a tourist destination and 5 in c

The association between relevant comorbidities and dementia in patients with atrial fibrillation

Risk of dementia is increased in patients with atrial fibrillation (AF). We aimed to study associations between relevant comorbidities and prevalent as well as incident dementia in AF patients. Study population included all adults (n = 12,283) ≥ 45 years diagnosed with AF at 75 primary care centers in Sweden 2001–2007. Logistic regression was used to calculate odds ratios (OR) with 95% confidence

The risk for drug abuse, alcohol use disorder, and psychosocial dysfunction in offspring from high-density pedigrees : its moderation by personal, family, and community factors

Previous high-risk family designs in psychiatry have focused largely on offspring of affected parents. We take a pedigree-based approach and examine the social, psychological, and psychiatric features of offspring from extended pedigrees selected for high-densities of alcohol use disorder (AUD) or drug abuse (DA). We identified, from the Swedish population, 665,715 pedigrees containing a mean of 1

In vitro evolution of antibodies inspired by in vivo evolution

In vitro generation of antibodies often requires variable domain sequence evolution to adapt the protein in terms of affinity, specificity, or developability. Such antibodies, including those that are of interest for clinical development, may have their origins in a diversity of immunoglobulin germline genes. Others and we have previously shown that antibodies of different origins tend to evolve a

Assertive discourse and folk linguistics : Serbian nationalist discourse about the cyrillic script in the 21st century

Ever since the wars of the Yugoslav secession in the nineties, linguistic nationalism has proven to have been among the more relevant instances in the discursive construction of national identity and new languages, dubbed by Ranko Bugarski as ‘administrative successors’ of Serbo-Croatian. Even though contemporary linguistics still classifies Serbo-Croatian as one language with regional varieties (

Normal vaginal delivery at term after expectant management of heterotopic caesarean scar pregnancy : A case report

Background: Heterotopic pregnancy with a combination of a caesarean scar pregnancy and an intrauterine pregnancy is rare and has potentially life-threatening complications. Case presentation: We describe the case of a 27-year-old white woman who had experienced an emergency caesarean delivery at 39 weeks for fetal distress with no postpartum complications. This is a report of the successful expect

Impact of Non-idealities on the Performance of InAs/(In)GaAsSb/GaSb Tunnel FETs

Measured InGaAsSb/InAs nanowire TFETs showing both, sub-60mV/dec slope and high ON-current, are simulated using calibrated TCAD. The focus is laid on the impact of non-idealities, such as hetero-interface traps, oxide-interface traps, and bulk traps on device characteristics. Simulated temperature-dependent transfer curves are in good agreement with the measured data which validates the simulation

Species diversity and abundance of dinoflagellate resting cysts seven months after a bloom of Alexandrium catenella in two contrasting coastal systems of the Chilean Inland Sea

In Chile, 90% of the fish farms and major natural shellfish beds are located in the region surrounding the Inland Sea, where over the last few decades harmful phytoplankton blooms have often been observed. The onset and recurrence of bloom events are often related to the resuspension and germination of resting cysts that have accumulated in the sediments. The degree of cyst settling, accumulation

Multi-period portfolio selection with drawdown control

In this article, model predictive control is used to dynamically optimize an investment portfolio and control drawdowns. The control is based on multi-period forecasts of the mean and covariance of financial returns from a multivariate hidden Markov model with time-varying parameters. There are computational advantages to using model predictive control when estimates of future returns are updated

Heparin-binding protein in sputum as a marker of pulmonary inflammation, lung function, and bacterial load in children with cystic fibrosis

Background: Cystic fibros.000000 bacterial pulmonary infections and neutrophil-dominated inflammation in the airways. The aim of this study was to evaluate the neutrophil-derived protein Heparin-binding protein (HBP) as a potential sputum marker of airway inflammation and bacterial load. Methods: Nineteen CF patients, aged 6-18 years, were prospectively followed for 6 months with sputum sampling a

Connective tissue growth factor contributes to joint homeostasis and osteoarthritis severity by controlling the matrix sequestration and activation of latent TGFβ

Objectives: One mechanism by which cartilage responds to mechanical load is by releasing heparin-bound growth factors from the pericellular matrix (PCM). By proteomic analysis of the PCM, we identified connective tissue growth factor (CTGF) and here investigate its function and mechanism of action. Methods: Recombinant CTGF (rCTGF) was used to stimulate human chondrocytes for microarray analysis.

Acute leukemia cells resistant to PI3K/mTOR inhibition display upregulation of P2RY14 expression

The PI3K/mTOR pathway is the second most frequently deregulated pathway in a majority of cancers such as breast cancer, lung cancer, and melanomas as well as leukemia. Mutations in the genes coding for receptor tyrosine kinases (RTKs) and G-protein-coupled receptors (GPCRs) are quite common in all forms of acute leukemia. This can be a major cause of deregulation of the PI3K-mTOR pathway. To under

The Novel PrisMax Continuous Renal Replacement Therapy System in a Multinational, Multicentre Pilot Setting

Background/Aims: We assessed how the novel PrisMax continuous renal replacement therapy (CRRT) system performed in a prospective international multicentre setting. We compared this device to its predecessor, the Prismaflex, with regards to multiple treatment parameters. Additionally, we performed a survey, aiming to measure user satisfaction. Methods: Data was prospectively collected from 7 intens

Recent past (1979-2014) and future (2070-2099) isoprene fluxes over Europe simulated with the MEGAN-MOHYCAN model

Isoprene is a highly reactive volatile organic compound emitted by vegetation, known to be a precursor of secondary organic aerosols and to enhance tropospheric ozone formation under polluted conditions. Isoprene emissions respond strongly to changes in meteorological parameters such as temperature and solar radiation. In addition, the increasing CO2 concentration has a dual effect, as it causes b
