Weeds constitute major constraints for farmers by reducing crop yield and quality. However, weeds are managed effectively using herbicides, but this may cause harmful effects on human health and the environment. In an experiment on weed seed predation, we tested the biological control potential of carabid beetles to combat weeds in the absence of herbicides. Seeds from three common weed species we
Abstract Background: Empowerment is essential in the rehabilitation process for people with psychiatric disabilities and knowledge about factors that may play a key role within this process would be valuable for further development of the day centre services. Objective: The present study investigates day centre attendees' perceptions of empowerment. The aim was to investigate which factors show th
AIMS/HYPOTHESIS: γ-Aminobutyric acid (GABA) is a signalling molecule in the interstitial space in pancreatic islets. We examined the expression and function of the GABA signalling system components in human pancreatic islets from normoglycaemic and type 2 diabetic individuals. METHODS: Expression of GABA signalling system components was studied by microarray, quantitative PCR analysis, immunohi
This article considers recent legal developments on undocumented migrant workers, finds the acceptance of international legal standards unsatisfactory and argues that the private law rights derived from the "semi-legal" employment contract between the employer and the undocumented migrant worker generates a solid base for significant legal claims. It further monitors the promotion of the position
This study explores patients' knowledge of cardiac risk factors (CRFs), analyses how information and advice about CRFs are documented in clinical practice, and assesses patient adherence to received instructions to decrease CRFs. Systemic lupus erythematosus (SLE) patients with >= 4 ACR criteria participated through completing a validated cardiovascular health questionnaire (CHQ). Kappa statistics
Cyclooxygenase-2 (COX-2) is an inducible enzyme that drives inflammation and is the therapeutic target for widely used nonsteroidal antiinflammatory drugs (NSAIDs). However, COX-2 is also constitutively expressed, in the absence of overt inflammation, with a specific tissue distribution that includes the kidney, gastrointestinal tract, brain, and thymus. Constitutive COX-2 expression is therapeuti
Mollusks have received increasing interest in ecotoxicological studies but so far the available scientific analyses of how their genes are affected by anthropogenic pollutants are scarce. The focus of this study is to identify an estrogen receptor (er) gene in the common prosobranch snail Bithynia tentaculata and to test a hypothesis that 17α-Ethinylestradiol (EE2) will modulate er gene expression
Background. A 57-year old man with low-back pain was found to have a 3 x 3 x 3 cm presacral neuroendocrine tumour (NET) with widespread metastases, mainly to the skeleton. His neoplastic disease responded well to peptide receptor radionuclide therapy (PRRT) with the radiotagged somatostatin agonist Lu-177-DOTATATE. During almost 10 years he was fit for a normal life. He succumbed to an intraspinal
Amplification of innate immune responses by endogenous danger-associated molecular patterns (DAMPs) promotes inflammation. The involvement of S100A8 and S100A9, DAMPs belonging to the S100 calgranulin family, in the pathogenesis of cardiovascular disease is attracting an increasing amount of interest. S100A8 and S100A9 (also termed MRP8 and MRP14) preferentially form the S100A8/A9 heterodimer (MRP
Aims: The neurotransmitter Neuropeptide Y (NPY) was previously reported as a minor autoantigen in newly diagnosed type 1 diabetes (T1D) patients. The single nucleotide polymorphism at rs16139 (T1128C, L7P) in the NPY gene was associated with an increased risk for the development of type 2 diabetes (T2D). We aimed to develop a radiobinding assay for NPY-L (Leucine) and NPY-P (Proline) autoantibodie
The need to reduce CO2 emissions from fossil-fuel based power production creates the need for new power plant solutions where the CO2 is captured and stored or reused. Different concepts to capture CO2 fall into the three main categories: 1. Precombustion decarbonization 2. Oxy-fuel combustion 3. Post-combustion removal of carbon. In the first two types of processes Oxygen Transport Membrane (OTM)
Both energy security and the demand for energy, particularly from renewable energy sources, as principle drivers, call for the investigation of renewable energy potential in Poland. The city of Zabrze, located in the Upper Silesia province and urban zone of Katowice, dedicates continuous efforts to the improvement of its waste management against the background of European Union Directives requirin
Leachate constitutes the main potential long-term environmental risk of landfill emissions. The EU landfill directive 1999/3 I/EC requires minimum monitoring during the active landfill life and the after-care phase. Due to time and resource limitations, monitoring of leachate quality is a compromise between information density and applicability. Samples from passively collected leachate are suspec
Most energy behaviour studies on households focus on the questions how and why we use energy and what can be done to lower energy consumption. Very few studies raise the question of when energy is used or examine the underlying explanations to load patterns. Due to economic and technical problems with electricity peak load, it is important to gain knowledge about how the load patterns of household
In order to meet the unprecedented challenge of feeding an increasing population while curbing associated environmental impacts a fundamental change in the current food system is required. Such a shift needs an active facilitator who could set and implement the sustainability agenda in the food supply chain. Recently, it has been argued that retailers might become a vital agent of change towards s
Load demand in residential houses is a significant contributor to peak load problems experienced by utilities. The knowledge about demand variation in households is fairly limited as well as the use of various tools to analyze the demand. Many utilities have recently installed interval (hourly) metering at their residential customers. The availability of hourly data is a significant progress, howe
