Alginate is a kind of marine-derived plant polysaccharide with useful properties including inherent flame-retardancy and biocompatibility, yet poor flowability and low processing efficiency induced by high viscosity impede its further industrial applications. In this study, PEG-substituted tertiary amines were adapted to functionalize alginate with different molecular weight via acid-base reaction to improve the flowability. Based on alginate with low molecular weight, alginate fluids exhibited excellent flowability at room temperature in the absence of solvent...

Neuronal activity is characterized by a diversity of oscillatory phenomena that are associated with multiple behavioral and cognitive processes, yet the functional consequences of these oscillations are not fully understood. Our aim was to determine whether and how these different oscillatory activities affect short-term synaptic plasticity (STP), using the olfactory system as a model. In response to odorant stimuli, the olfactory bulb displays a slow breathing rhythm as well as beta and gamma oscillations...

Miscibility is an important issue in biopolymer blends for analysis of the behavior of polymer pairs through the detection of phase separation and improvement of the mechanical and physical properties of the blend. This study presents the formulation of a stable and one-phase mixture of collagen and regenerated silk fibroin (RSF), with the highest miscibility ratio between these two macromolecules, through inducing electrostatic interactions, using salt ions. For this aim, a ternary phase diagram was experimentally built for the mixtures, based on observations of phase behavior of blend solutions with various ratios...

Reformulation of food products to reduce salt content has been a central strategy for achieving population level salt reduction. In this paper, we reflect on current reformulation strategies and consider how consumer behavior determines the ultimate success of these strategies. We consider the merits of adopting a 'health by stealth', silent approach to reformulation compared to implementing a communications strategy which draws on labeling initiatives in tandem with reformulation efforts. We end this paper by calling for a multi-actor approach which utilizes co-design, participatory tools to facilitate the involvement of all stakeholders, including, and especially, consumers, in making decisions around how best to achieve population-level salt reduction...

This study tested a structural model examining the effects of perceived usefulness, perceived ease of use, attitude, subjective norm, perceived behavioral control, health consciousness, and application-specific self-efficacy on the acceptance (i.e. behavioral intention and actual usage) of a computer-based chronic disease self-monitoring system among patients with type 2 diabetes mellitus and/or hypertension. The model was tested using partial least squares structural equation modeling, with 119 observations that were obtained by pooling data across three time points over a 12-week period...

The present study examined wear characteristics of A356/melon shell ash particulate composites. Dry-sliding the stainless steel ball against specimen disc revealed the abrasive wear behavior of the composites under loads of 2 and 5N. The composite showed lower wear rate of 2.182 × 10(-4) mm(3)/Nm at 20 wt% reinforced material under load of 5N. Results showed that wear rate decreased significantly with increasing weight percentage of melon shell ash particles. Microstructural analyses of worn surfaces of the composites reveal evidence of plastic deformation of matrix phase...

Higher organisms as well as medical and technological materials exploit mineral-polymer interactions, however, mechanistic understanding of these interactions is poorly constrained. Dynamic force spectroscopy can probe the free energy landscape of interacting bonds, but interpretations are challenged by the complex mechanical behavior of polymers. Here we restate the difficulties inherent to applying DFS to polymer-linked adhesion and present an approach to gain quantitative insight into polymer-mineral binding...

Learning and memory play a central role in behavior and communication of foraging bees. We already showed that chronic uptake of the neonicotinoid thiacloprid affects the behavior of honey bees in the field. Foraging behavior, homing success, navigation performance, and social communication were impaired. Thiacloprid collected at a feeding site at low doses accumulates in foragers over time. Here we applied a laboratory standard procedure, the proboscis extension response (PER) conditioning, in order to assess which processes, acquisition, memory consolidation and/or memory retrieval were compromised after bees were fed either with thiacloprid or the formulation of thiacloprid named Calypso(®) at 3 different sublethal doses...

The DOCK-AND-LOCK (DNL®) method is a platform technology that combines recombinant engineering and site-specific conjugation to create multispecific, multivalent antibodies of defined composition with retained bioactivity. We have applied DNL® to generate a novel class of trivalent bispecific antibodies (bsAbs), each comprising an anti-CD3 scFv covalently conjugated to a stabilized dimer of different anti-tumor Fabs. Here we report the further characterization of two such constructs, (E1)-3s and (14)-3s, which activate T cells and target Trop-2- and CEACAM5-expressing cancer cells, respectively...

This article reports anodization of Mg in KOH electrolyte and the associated surface, degradation, and biological properties for bioresorbable implant applications. The preparation procedures for electrodes and anodization setup significantly enhanced reproducibility of samples. The results of anodization performed at the applied potentials of 1.8, 1.9, or 2.0 V showed that the sample anodized at 1.9 V and annealed, referred to as the 1.9 AA sample, had homogenous surface microstructure and elemental composition, and a reduction in corrosion current density in the electrochemical testing...

The adsorption and desorption of D2O on hydrophobic activated carbon fiber (ACF) occurs at a smaller pressure than the adsorption and desorption of H2O. The behavior of the critical desorption pressure difference between D2O and H2O in the pressure range of 1.25-1.80kPa is applied to separate low concentrated D2O from water using the hydrophobic ACF, because the desorption branches of D2O and H2O drop almost vertically. The deuterium concentration of all desorbed water in the above pressure range is lower than that of water without adsorption-treatment on ACF...

OBJECTIVE: Since the 1990s, self-controlled designs including self-controlled case series (SCCS) studies have been occasionally used in post-marketing evaluation of drug or vaccine safety. An SCCS study was tentatively applied to evaluate the relationship between oseltamivir use and abnormal behavior Type A (serious abnormal behavior potentially leading to an accident or harm to another person) in influenza patients. METHODS: From the original prospective cohort study with approximately 10,000 Japanese children and adolescents with influenza (aged <18years), 28 subjects (mean age: 7...

There is insufficient research examining the implementation of complex novel interventions within health care. This may be due to a lack of qualitative research providing subjective insights into these implementation processes. The authors investigate the advantages of applying behavior change theories to conceptualize qualitative data describing the processes of implementation of complex interventions. Breaking Free Online (BFO), a digital treatment intervention for substance misuse, is described as an example of a complex intervention...

There is a need for new, targeted smoking cessation interventions for smokers living with HIV. The Information-Motivation-Behavioral Skills (IMB) model has been applied effectively to HIV-related health behaviors and was used in this qualitative study to elicit factors that could lead to the development of innovative and successful cessation interventions for this population. Twenty individuals who smoked from two clinics providing care to people living with HIV participated in open-ended interviews, responding to questions covering the domains of the IMB model, as applied to smokers living with HIV...

OBJECTIVE: Psychiatric symptomatology during childhood predicts persistent mental illness later in life. While neuroimaging methodologies are routinely applied cross-sectionally to the study of child and adolescent psychopathology, the nature of the relationship between childhood symptoms and the underlying neurodevelopmental processes remains unclear. The authors used a prospective population-based cohort to delineate the longitudinal relationship between childhood psychiatric problems and brain development...

INTRODUCTION: Self-care is a crucial aspect in the management of chronic diseases. People with motor neuron disease (MND) live with a chronic degenerative condition in rapid evolution, which leads them to high dependencies. During their illness, they must apply several behaviors including adherence to ventilation and nutritional therapy. OBJECTIVE: The purpose of this review is to systematically explore the concept of self-care for people with MND. METHOD: An integrative review of the literature has been conducted...

We analyzed the concept of risk compensation and how it has been applied in HIV prevention, paying particular attention to the strategy of HIV preexposure prophylaxis (PrEP). In risk compensation, reduced perceptions of risk after the introduction of a preventative intervention lead to more frequent risk-taking behavior. Such a change may undermine the intervention's protective benefits. We found that many studies purporting to investigate risk compensation do not assess or report changes in perceptions of risk, instead relying on behavioral measures...

Highly (001)-textured BiFeO3 film in tetragonal phase (T-BFO) with a giant c/a ratio was firstly obtained on quartz/polycrystalline ITO substrate. Our results indicate that the polycrystalline ITO layer with small surface roughness is a critical point to control the growth of T-BFO structure. It should be ascribed to the fact that a Bi-rich phase interlayer (~5 nm) could be formed on ITO, which acted as a crystal seed layer and thus induced the growth of (001)-textured T-BFO structure. The observed weak room temperature ferromagnetism should be attributed to Fe valance change...

Both babies and their parents may experience a stay in the newborn intensive care unit (NICU) as a traumatic or a 'toxic stress,' which can lead to dysregulation of the hypothalamic-pituitary-adrenal axis and ultimately to poorly controlled cortisol secretion. Toxic stresses in childhood or adverse childhood experiences (ACEs) are strongly linked to poor health outcomes across the lifespan and trauma-informed care is an approach to caregiving based on the recognition of this relationship. Practitioners of trauma-informed care seek to understand clients' or patients' behaviors in light of previous traumas they have experienced, including ACEs...

Spirulina maxima is a microalgae which contains flavonoids and other polyphenols. Although Spirulina maxima 70% ethanol extract (SM70EE) has diverse beneficial effects, its effects on neurotoxicity have not been fully understood. In this study, we investigated the neuroprotective effects of SM70EE against trimethyltin (TMT)-induced neurotoxicity in HT-22 cells. SM70EE inhibited the cleavage of poly-ADP ribose polymerase (PARP). Besides, ROS production was decreased by down-regulating oxidative stress-associated enzymes...
