The sophistication, complexity and intelligence of biological systems is a continuous source of inspiration for mankind. Mimicking the natural intelligence to devise tiny systems that are capable of self-regulated, autonomous action to, for example, distinguish different targets, remains among the grand challenges in biomimetic micro-robotics. Herein, we demonstrate an autonomous soft device, a light-driven flytrap, that uses optical feedback to trigger photomechanical actuation. The design is based on light-responsive liquid-crystal elastomer, fabricated onto the tip of an optical fibre, which acts as a power source and serves as a contactless probe that senses the environment...

The current study used data from two longitudinal samples to test whether self-regulation, depressive symptoms, and aggression/antisociality were mediators in the relation between a polygenic score indexing serotonin (5-HT) functioning and alcohol use in adolescence. The results from an independent genome-wide association study of 5-hydroxyindoleacetic acid in the cerebrospinal fluid were used to create 5-HT polygenic risk scores. Adolescents and/or parents reported on adolescents' self-regulation (Time 1), depressive symptoms (Time 2), aggression/antisociality (Time 2), and alcohol use (Time 3)...

Periodontitis affects the attachment of natural teeth, and infection or inflammation associated with periodontitis may affect peri-implant tissues. Enamel matrix derivative (EMD) proteins provide stimulation for self-regeneration of the damaged tissue when applied to wide intrabony defects as part of a mixture with bone graft material. As a first step of the process enhancing cell proliferation and ligament formation, we demonstrated that EMD protein precipitation depends strongly on the physical and chemical characteristics of the bone grafts used in the mixture...

Diabetes mellitus affects millions of people worldwide and requires that individuals tightly self-regulate their blood glucose levels to minimize the associated secondary complications. Continuous monitoring devices potentially offer patients a long-term means to tightly monitor their glucose levels. In recent years, fluorescent affinity sensors based on lectins (e.g., Concanavalin A (ConA)) have been implemented in such devices. Traditionally, these sensors pair the lectin with a multivalent ligand, like dextran, in order to develop a competitive binding assay that changes its fluorescent properties in response to the surrounding glucose concentrations...

Despite recent attempts to use electroencephalogram (EEG) neurofeedback (NFB) as a tool for rehabilitation of motor stroke, its potential for improving neurological impairments of attention-such as visuospatial neglect-remains underexplored. It is also unclear to what extent changes in cortical oscillations contribute to the pathophysiology of neglect, or its recovery. Utilizing EEG-NFB, we sought to causally manipulate alpha oscillations in 5 right-hemisphere stroke patients in order to explore their role in visuospatial neglect...

To date, there is no validated measure for pain catastrophizing at the daily level. The Pain Catastrophizing Scale (PCS) is widely used to measure trait pain catastrophizing. We sought to develop and validate a brief, daily version of the PCS for use in daily diary studies in order to facilitate research on mechanisms of catastrophizing treatment, individual differences in self-regulation, and to reveal the nuanced relationships between catastrophizing, correlates, and pain outcomes. After adapting the PCS for daily use, we evaluated the resulting 14 items using 3 rounds of cognitive interviews with 30 adults with chronic pain...

OBJECTIVE: The clinical literature on ADHD in adults suggests that "overly positive" or optimistic cognitions may contribute to impairment and failure to use self-regulation skills in this population, yet the research literature on this topic is limited. We developed the ADHD Cognitions Scale (ACS), a brief self-report measure of ADHD-related thoughts, and evaluated its psychometric properties. METHOD: We collected self-report measures, inculding the ACS, from two large community samples ( Ns = 262, 304)...

Mechanisms for automatic emotion regulation (AER) are essential during childhood as they offset the impact of unwanted or negative emotional responses without drawing on limited attentional resources. Despite the importance of AER in improving the efficiency and flexibility of self-regulation, few research studies have investigated the underlying neurophysiological mechanisms. To fill this gap, we used magnetoencephalography (MEG) to investigate AER-related brain processes in 25 children (∼10 years old) who performed a go/no-go task that included an incidental exposure to faces containing socio-emotional cues...

Periodic ion-conduction oscillation of biological ion channels in a living system is essential for numerous life processes. Here we report an oscillatory nanofluidic system that can self-regulate its ion-conduction states under constant conditions. The oscillatory nanofluidic system is constructed by integrating a chemical oscillator into an artificial single nanochannel system. Oscillating chemical reactions of the pH oscillator carried out inside the nanochannel are used to switch the surface properties of the channel between highly and lowly charged states, thus realizing an autonomous, continuous and periodic oscillation of the ion conductance of the channel between high and low ion-conduction states...

OBJECTIVES: The present research investigated whether Temporal Self-Regulation Theory (TST) can be used to help understand healthy and unhealthy eating intentions and behaviour. DESIGN: A prospective design with two waves of data collection one week apart. METHOD: An online survey measured the key components of TST (i.e., connectedness, timing and valence beliefs, intentions, past behaviour, habit strength, perceived environmental cues, and self-control) with respect to eating fruit and vegetables (F&V; N = 133) or unhealthy snacks (N = 125)...

In medical education, students are increasingly regarded as active seekers of feedback rather than passive recipients. Previous research showed that in the intentions of students to seek feedback, a learning and performance goal can be distinguished. In this study, we investigated the intentions (defined as level and orientation of motivation) of different performing students (low, average, and high performing students) to seek feedback in the clinical workplace using Self-Determination Theory. We conducted a quantitative study with students in their clinical clerkships and grouped them based on their performance...

Driving ability in the elderly and cognitively impaired is of growing demographic relevance. Driving represents a complex task for which multiple central resources are needed. In mild cognitive impairment and dementia, we need to closely monitor driving ability, as it gets irrecoverably lost in the course of the disease. In normal aging, people are often able to self-regulate driving behavior with respect to their medical conditions. Some studies demonstrated that older drivers perform well compared with younger drivers...

OBJECTIVE: As an art form, drawings can facilitate the tangible expression of patients' inner images and feelings in a range of health conditions. However, there are currently no published studies investigating adults' perspectives of asthma using drawings. This study aimed to explore how adults' drawings illustrate their perceptions and experiences of asthma. METHODS: Adults with asthma participated in a one-on-one drawing activity. Analysis was grounded in the participants' accounts of their drawing, which were examined alongside the relevant image...

INTRODUCTION: The relationship between physicians and pharmaceutical-companies raises many dilemmas. There are two types of solutions to these dilemmas: self-regulation and government regulation. Our goal was to review in what way legislative intervention and self-regulation standardize and affect the relationship. In addition, we examined the positions of relevant stakeholders regarding: 1. The relationship between physicians and pharmaceutical companies; 2. Future measures we should take to address the ethical dilemmas inherent in this relationship...

The large surface-to-volume ratio of GaN nanowires implicates sensitivity of the optical and electrical properties of the nanowires to their surroundings. The implementation of an (Al,Ga)N shell with a larger band gap around the GaN nanowire core is a promising geometry to seal the GaN surface. We investigate the luminescence and structural properties of selective area-grown GaN-(Al,Ga)N core-shell nanowires grown on Si and diamond substrates. While the (Al,Ga)N shell allows a suppression of yellow defect luminescence from the GaN core, an overall intensity loss due to Si-related defects at the GaN/(Al,Ga)N interface has been observed in the case of Si substrates...

BACKGROUND: The outbreak of the Ebola virus disease (EVD) in West Africa in December 2013 was the largest Ebola outbreak in history. This study aimed to measure the underlying contextual and psychosocial factors of intentions to perform Ebola prevention behaviours (not touching people who might be suffering from Ebola, reporting suspected cases to the National Ebola Hotline, NEH) in Guinea-Bissau. Geographical location, cross-border market activities, poor water, sanitation and hygiene (WASH) conditions, and burial practices in some communities pose a serious risk in terms of potential EVD outbreak and seriously hamper its prevention in Guinea-Bissau...

Based on self-regulation and self-efficacy theories, the Cancer Behavior Inventory (CBI; Heitzmann et al., 2011; Merluzzi & Martinez Sanchez, 1997; Merluzzi, Nairn, Hegde, Martinez Sanchez, & Dunn, 2001) was developed as a measure of self-efficacy strategies for coping with cancer. In the latest revision, CBI-V3.0, a number of psychometric and empirical advances were made: (a) the reading level was reduced to 6th-grade level; (b) individual interviews and focus groups were used to revise items; (c) a new spiritual coping subscale was added; (d) data were collected from 4 samples (total N = 1,405) to conduct an exploratory factor analysis with targeted rotation, 2 confirmatory factor analyses, and differential item functioning; (e) item trimming was used to reduce the total number to 27; (f) internal consistency and test-retest reliability were computed; and (g) extensive validity testing was conducted...

BACKGROUND: Evolution preserves social attention due to its key role in supporting survival. Humans are attracted to social cues from infancy, but the neurobiological mechanisms for the development of social attention are unknown. An evolutionary-based, vertical-hierarchical theoretical model of self-regulation suggests that neonatal brainstem inputs are key for the development of well-regulated social attention. METHODS: Neonates born preterm (N = 44, GA 34 w...

BACKGROUND: Many young people who receive psychiatric care in inpatient or residential settings in North America have experienced various forms of emotional trauma. Moreover, these settings can exacerbate trauma sequelae. Common practices, such as seclusion and restraint, put young people at risk of retraumatization, development of comorbid psychopathology, injury, and even death. In response, psychiatric and residential facilities have embraced trauma-informed care (TIC), an organizational change strategy which aligns service delivery with treatment principles and discrete interventions designed to reduce rates of retraumatization through responsive and non-coercive staff-client interactions...
