Some problems of local development : The example of former state agricultural farms in Poland

The paper aims at examining the levels of social cohesion and socio-economic dysfunctionality in former State Agricultural Farms (post-PGR) areas and at assessing the possibilities for initiating bottom-up actions, and for participating in the creation of mechanisms for local development. Data used in the study was obtained in multimethods approach, i.e. mainly during a questionnaire survey, in-de

Biotechnological Potential of Bdellovibrio and Like Organisms and Their Secreted Enzymes

Bdellovibrio and like organisms (BALOs) are obligate predatory bacteria that selectively prey on a broad range of Gram-negative bacteria, including multidrug-resistant human pathogens. Due to their unique lifestyle, they have been long recognized as a potential therapeutic and biocontrol agent. Research on BALOs has rapidly grown over the recent decade, resulting in many publications concerning mo

Impact of Multiple Injection Strategies on Performance and Emissions of Methanol PPC under Low Load Operation

There is growing global interest in using renewable alcohols to reduce the greenhouse gases and the reliance on conventional fossil fuels. Recent studies show that methanol combined with partially premixed combustion provide clear performance and emission benefits compared to conventional diesel diffusion combustion. Nonetheless, high unburned hydrocarbon (HC) and carbon monoxide (CO) emissions ca

A Systematic Review and Meta-analysis of Delay in Radical Cystectomy and the Effect on Survival in Bladder Cancer Patients

CONTEXT: The complexity of bladder cancer diagnosis and staging results in delays in definitive treatment of muscle-invasive bladder cancer by radical cystectomy. OBJECTIVE: This systematic review and meta-analyses aim to assess the impact of delays in radical cystectomy. EVIDENCE ACQUISITION: A systematic review was conducted by searching Medline and Ovid Gateway using protocol-driven search term

Whole-genome analysis across 10 songbird families within Sylvioidea reveals a novel autosome-sex chromosome fusion

Sex chromosomes in birds have long been considered to be extremely stable. However, this notion has lately been challenged by findings of independent autosome-sex chromosome fusions within songbirds, several of which occur within a single clade, the superfamily Sylvioidea. To understand what ecological and evolutionary processes drive changes in sex chromosome systems, we need complete description

Imaging small molecule-induced endosomal escape of siRNA

Small interfering RNAs (siRNAs) are a new class of promising therapeutic molecules that can be used for sequence-specific downregulation of disease-causing genes. However, endosomal entrapment of siRNA is a key hurdle for most delivery strategies, limiting the therapeutic effect. Here, we use live-cell microscopy and cytosolic galectin-9 as a sensor of membrane damage, to probe fundamental propert

Brain Metabolism Alterations in Type 2 Diabetes : What Did We Learn From Diet-Induced Diabetes Models?

Type 2 diabetes (T2D) is a metabolic disease with impact on brain function through mechanisms that include glucose toxicity, vascular damage and blood–brain barrier (BBB) impairments, mitochondrial dysfunction, oxidative stress, brain insulin resistance, synaptic failure, neuroinflammation, and gliosis. Rodent models have been developed for investigating T2D, and have contributed to our understand

Tumour-suppressive effect of oestrogen receptor β in colorectal cancer patients, colon cancer cells, and a zebrafish model

Oestrogen receptor β (ERβ) has been suggested to have anti-proliferative and anti-tumour effects in breast and prostate cancer cells, but other studies have indicated its tumour-promoting effects. Understanding the complex effects of this receptor in different contexts requires further study. We reported that high ERβ expression is independently associated with improved prognosis in female colorec

Time-frequency feature extraction for classification of episodic memory

This paper investigates the extraction of time-frequency (TF) features for classification of electroencephalography (EEG) signals and episodic memory. We propose a model based on the definition of locally stationary processes (LSPs), estimate the model parameters, and derive a mean square error (MSE) optimal Wigner-Ville spectrum (WVS) estimator for the signals. The estimator is compared with stat

The coexistence of the streaming instability and the vertical shear instability in protoplanetary disks

The streaming instability is a leading candidate mechanism to explain the formation of planetesimals. However, the role of this instability in the driving of turbulence in protoplanetary disks, given its fundamental nature as a linear hydrodynamical instability, has so far not been investigated in detail. We study the turbulence that is induced by the streaming instability as well as its interacti

Hermeneutic observational studies : describing a method

There is a need to develop and use research observations in the clinical field, primarily to gain insight into and assess evidence of what comprises caring in a real-life situation and confirm what is actually taking place. In addition, assessments lead to a new and different understanding of what caring constitutes, thereby enabling the identification of what kind of care is being provided and is

Facing the unfamiliar : Nurses’ transcultural care in intensive care – A focus group study

Introduction: Western Europe today is a culturally diverse society and expected to become more so in the future. When patients from unfamiliar cultures become critically ill and require intensive care, this places considerable demands on the cultural and linguistic competencies of the intensive care staff. Existing research regarding the transcultural aspects of intensive care is scarce and, in Sw

Room Design - A Phenomenological-Hermeneutical Study : A Factor in Creating a Caring Environment

Medical technology has progressed tremendously over the last few decades, but the same development cannot be seen in the design of these intensive care unit environments. Authors report results of a study of evidence-based room design, emphasizing the impact on conveying a caring attitude to patients. Ten nonparticipant observations were conducted in patient rooms with 2 different designs, followe

The prognostic impact of FLT3-ITD and NPM1 mutation in adult AML is age-dependent in the population-based setting

In acute myeloid leukemia (AML) FLT3 internal tandem duplication (ITD) and nucleophosmin 1 (NPM1) mutations provide prognostic information with clinical relevance through choice of treatment, but the effect of age and sex on these molecular markers has not been evaluated. The Swedish AML Registry contains data on FLT3-ITD and NPM1 mutations dating to 2007, and 1570 adult patients younger than 75 y

Global Modern Charcoal Dataset (GMCD) : A tool for exploring proxy-fire linkages and spatial patterns of biomass burning

Progresses in reconstructing Earth's history of biomass burning has motivated the development of a modern charcoal dataset covering the last decades through a community-based initiative called the Global Modern Charcoal Dataset (GMCD). As the frequency, intensity and spatial scale of fires are predicted to increase regionally and globally in conjunction with changing climate, anthropogenic activit

Investigation of mechanical and thermal loads in pcBN tooling during machining of Inconel 718

This study investigates machining superalloy Inconel 718 with polycrystalline cubic boron nitride (pcBN) tooling both numerically and experimentally. Particular attention is given to mechanical and thermal stresses in the cutting tool arising from segmented chip formation and associated forces and temperatures. The temperature dependence of the mechanical properties of pcBN has been investigated a

European LeukemiaNet 2020 recommendations for treating chronic myeloid leukemia

The therapeutic landscape of chronic myeloid leukemia (CML) has profoundly changed over the past 7 years. Most patients with chronic phase (CP) now have a normal life expectancy. Another goal is achieving a stable deep molecular response (DMR) and discontinuing medication for treatment-free remission (TFR). The European LeukemiaNet convened an expert panel to critically evaluate and update the evi

Nanoprobe-Enabled Electron Beam Induced Current Measurements on III-V Nanowire-Based Solar Cells

Electron beam induced current (EBIC) is a well-established tool to, among others, locate and analyze p-n junctions, Schottky contacts or heterostructures in planar devices and is now becoming essential to study and optimize devices at the nanoscale, like III-V nanowire (NW) based solar cells. Here, we report on EBIC measurements on III-V single NW solar cells as well as on fully processed NW devic
