The NSAID diclofenac is controversially discussed with respect to its environmental relevance. Since further information is need to assess whether diclofenac should be included as substance of priority in the EU water framework directive, we investigated the impact of this analgesic on the embryonic development of brown trout (Salmo trutta f. fario) from fertilized egg until the end of sac-fry stage and studied effects in juvenile fish six months post hatch. Embryos were exposed to five test concentrations (0...

Heat treatment was one of the first transformative technologies in the southern African Middle Stone Age (MSA), with many studies in the Cape coastal zone of South Africa identifying it as an essential step in the preparation of silcrete prior to its use in stone tool manufacture. To date, however, no studies have investigated whether heat treatment is necessary for all silcrete types, and how geographically widespread heat treatment was in the subcontinent. The aim of this study is to investigate experimentally whether heat treatment continued further north into the Kalahari Desert of Botswana and northernmost South Africa, the closest area with major silcrete outcrops to the Cape...

BACKGROUND/AIMS: Despite reporting high levels of burden, supporters of people with young onset dementia (YOD) underuse formal community services. Previous quantitative studies in YOD are of limited utility in guiding service design because they did not consider important contextual barriers to service use. The aim of this study was to identify all relevant barriers and describe the service features considered most important to improving uptake by people with YOD and their supporters...

The Himalayan endemic alpine genus Roscoea, like other members of ginger family, exhibits the combination of floral traits that would fit pollination by long distant foragers such as bees, birds or flies. We studied the pollination biology of Roscoea alpina, observed potential floral visitors and determined their foraging behaviour, visitation frequency and pollination efficiency, to seek evidence in support of the pollination syndrome hypothesis. We also measured the floral spectra of R. alpina flowers to evaluate if signals fit with the currently known framework for observed floral visitors...

The cortex represents information across widely varying timescales. For instance, sensory cortex encodes stimuli that fluctuate over few tens of milliseconds, whereas in association cortex behavioural choices can require the maintenance of information over seconds. However, it remains poorly understood whether diverse timescales result mostly from features intrinsic to individual neurons or from neuronal population activity. This question remains unanswered, because the timescales of coding in populations of neurons have not been studied extensively, and population codes have not been compared systematically across cortical regions...

: HIV acquisition during pregnancy and postpartum periods remains high despite increased access to and initiation of antiretroviral therapy in sub-Saharan Africa. Moreover, maternal seroconversion during pregnancy and breastfeeding remains a source of significant paediatric HIV infection in the region. In order to curb vertical HIV transmission, HIV acquisition during pregnancy and lactation must significantly decline. Biological and behavioural factors contribute to high HIV incidence, including hormonal changes that alter genital mucosal surfaces, and frequent condomless sex with HIV-infected partners or partners of unknown serostatus...

BACKGROUND: Clinical experience highlights the wide heterogeneity of primary prostate cancer (PPCa), even when potentially related to the same grade and stage. Currently available prediction tools and biomarkers do not always allow for early recognition of PPCa aggressive phenotype, sometimes making it impossible to distinguish among men harbouring indolent tumours or life-threatening disease. OBJECTIVE: To establish a novel ex vivo/in vitro model suitable to estimate the invasive phenotype of PPCa cells (PPCaC)...

Behavioural disturbances are frequently found after aneurysmal subarachnoid haemorrhage (aSAH). Social cognition impairments have been suggested as a possible underlying mechanism for behavioural problems. Also, aSAH is likely to result in damage affecting frontal-subcortical circuits underlying social cognition. Therefore, we aimed to investigate social cognition after aSAH and its associations with behavioural problems (deficits in interpersonal behaviour, apathy, and impaired self-awareness) and focal as well as diffuse brain damage...

The utility of tandem ion mobility mass spectrometry coupled with electronic spectroscopy to investigate protomer-specific photochemistry is demonstrated by measuring the photoisomerization response for protomers of protonated 4-dicyanomethylene-2-methyl-6-para-dimethylaminostyryl-4H-pyran (DCM) molecules. The target DCMH(+) species, has three protomers that are distinguished by their different collision cross-sections with He, N2, and CO2 buffer gases, trends in abundance with ion source conditions, and from their photoisomerization responses...

In many biotechnological applications, it is useful for gene expression to be regulated by multiple signals, as this allows the programming of complex behaviour. Here we implement, in Escherichia coli, a system that compares the concentration of two signal molecules, and tunes GFP expression proportionally to their relative abundance. The computation is performed via molecular titration between an orthogonal σ factor and its cognate anti-σ factor. We use mathematical modelling and experiments to show that the computation system is predictable and able to adapt GFP expression dynamically to a wide range of combinations of the two signals, and our model qualitatively captures most of these behaviours...

AIMS AND OBJECTIVES: To describe the tailoring of the Tell-us Card intervention for enhanced patient participation to the Dutch hospital setting by using Intervention Mapping as a systematic approach. BACKGROUND: Even though patient participation is essential in any patient to nurse encounter, care plans often fail to take patients' preferences into account. The Tell-us Card intervention seems promising, but needs to be tailored and tested before implementation in a different setting or on large scale...

Molecule clustering is an important mechanism underlying cellular self-organization. In the cell membrane, a variety of fundamentally different mechanisms drive membrane protein clustering into nanometre-sized assemblies. To date, it is unknown whether this clustering process can be dissected into steps differentially regulated by independent mechanisms. Using clustered syntaxin molecules as an example, we study the influence of a cytoplasmic protein domain on the clustering behaviour. Analysing protein mobility, cluster size and accessibility to myc-epitopes we show that forces acting on the transmembrane segment produce loose-clusters, while cytoplasmic protein interactions mediate a tightly packed state...

As in other areas of international development, we are witnessing the proliferation of 'traveling models' developed by international experts and introduced in an almost identical format across numerous countries to improve some aspect of maternal health systems in low- and middle-income countries. These policies and protocols are based on 'miracle mechanisms' that have been taken out of their original context but are believed to be intrinsically effective in light of their operational devices.In reality, standardised interventions are, in Africa and elsewhere, confronted with pragmatic implementation contexts that are always varied and specific, and which lead to drifts, distortions, dismemberments and bypasses...

BACKGROUND: This study investigated whether intramuscular injection of delta-9-tetrahydrocannabinol (THC), by acting on peripheral cannabinoid (CB) receptors, could decrease nerve growth factor (NGF)-induced sensitization in female rat masseter muscle; a model which mimics the symptoms of myofascial temporomandibular disorders. METHODS: Immunohistochemistry was used to explore the peripheral expression of cannabinoid receptors in the masseter muscle while behavioural and electrophysiology experiments were employed to assess the functional effects of intramuscular injection of THC...

OBJECTIVES: This study aims at testing predictions derived from temporal self-regulation theory (TST) in relation to discretionary food choices (snacks). TST combines a motivational sphere of influence (cognitions and temporal valuations resulting in intentions) with a momentary sphere (encompassing social and physical environmental cues). This dual approach differs from current health behaviour theories, but can potentially improve our understanding of the interplay of personal and environmental factors in health behaviour self-regulation...

BACKGROUND: Triticale gluten still remains very poorly characterized rheologically. In this study the mechanical spectra of gluten isolated from four triticale cultivars were registered and fitted with Cole-Cole functions yielding the viscoelastic plateau parameters. Master spectra were calculated. Retardation test was performed and used to calculate the composite mechanical spectra and the width of viscoelastic plateau l. Protein fractional composition of triticale flour and gluten was studied using capillary zone electrophoresis...

The presence of carbonates in inclusions in diamonds coming from depths exceeding 670 km are obvious evidence that carbonates exist in the Earth's lower mantle. However, their range of stability, crystal structures and the thermodynamic conditions of the decarbonation processes remain poorly constrained. Here we investigate the behaviour of pure iron carbonate at pressures over 100 GPa and temperatures over 2,500 K using single-crystal X-ray diffraction and Mössbauer spectroscopy in laser-heated diamond anvil cells...

Background To date, no drugs have been approved for gambling disorder. Numerous publications have described the value of opioid antagonists. Indeed, the mesocorticolimbic dopaminergic pathway has been suggested as the underlying cause of reward-seeking behaviour, and it is modulated by the opioid system. Objective This study aims to evaluate the relevance of opioid antagonists for treating GD. Method A systematic literature review was conducted. A search of the PubMed electronic database, PsycINFO and the Cochrane Systematic Review Database without any limits was performed...
