BACKGROUND: Regular physical activity (PA) is beneficial for physical and psychological well-being, yet many people do not achieve these health benefits due to irregular PA participation which is also known as fluctuation. Limited attention has been given to the phenomenon of fluctuation in the PA behaviour literature. OBJECTIVE: The aim of this review was to explore and to map definitions, measurements, behavioural evidence, and factors related to PA fluctuation...

Retinoic acid (RA) is a vital morphogen for early patterning and organogenesis in the developing embryo. RA is a diffusible, lipophilic molecule that signals via nuclear RA receptor heterodimeric units that regulate gene expression by interacting with RA response elements in promoters of a significant number of genes. For precise RA signaling, a robust gradient of the morphogen is required. The developing embryo contains regions that produce RA, and specific intracellular concentrations of RA are created through local degradation mediated by Cyp26 enzymes...

Self-Directed Learning (SDL) and Self-Regulated Learning (SRL) are often used without a clear distinction, leading to confusion in understanding and the use of inappropriate measurement tools. SDL is a general approach to learning and can be identified using 'aptitude' questionnaires but SRL is a dynamic and context specific learning process and requires 'event' measures, such as microanalysis. These differences have implications for research and remediation.

There remains intense interest in tractable approaches to target or silence the KRAS oncoprotein as a rational therapeutic strategy to attack pancreatic adenocarcinoma (PDAC) and other cancers which overexpress it. Here we provide evidence that accumulation of the KRAS oncoprotein is controlled by a self-regulating feed-forward regulatory loop that utilizes a unique hypusinated isoform of the translation elongation factor eIF5A and the tyrosine kinase PEAK1. Oncogenic activation of KRAS increased eIF5A-PEAK1 translational signaling, which in turn facilitated increased KRAS protein synthesis...

OBJECTIVE: Interoception deficits have been associated with various points on the suicidality continuum. Most research, however, has focused on general, rather than specific facets of, interoception. This study compared individuals with lifetime suicidal ideation, plans, and attempts using a multidimensional assessment of interoception. METHOD: A total of 537 adults completed measures of their interoception and lifetime suicide histories. RESULTS: Individuals with lifetime suicidal ideation reported more worry about their bodily sensations...

Karen M Schwartz
I contend that painting, like psychoanalytic psychotherapy, is an intersubjective process able to connect hearts and minds of painters and viewers alike, because the creative process of making a painting brings painters into more complex and more animated relationship with themselves. My own painting process is largely nonverbal. Interactions between me and my evolving artwork-in-process reveal experiences, thoughts, and feelings not yet formulated in words, and so, not available explicitly to conscious awareness until visual representation allows questions of meaning and intention to be thought about and elaborated in the usual, verbal sense...

Trauma and stress, like that which occurs as a result of adverse childhood experiences (ACEs), can change brain structure and function, especially in medial prefrontal and hippocampal areas, and can impact self-regulatory skill. The error-related negativity (ERN) is a medial frontal negative event-related potential (ERP) component that is more negative when a participant makes an erroneous versus correct response. We investigated the association of ACEs to adolescents' ERN and self-regulation. Forty-three 12-15 year olds performed a flanker task while EEG data were recorded...

Drawing from a self-regulation perspective, we examine how intrinsic work motivation changes the relation between workplace ostracism and employee job performance via self-leadership. We test a moderated mediated model with data collected from 101 employees at two points in time. Results provide support for the hypothesis that ostracized employees who are more intrinsically motivated use self-leadership strategies to a greater degree to improve their job performance than their counterparts who are not intrinsically motivated...

Objective: To address the stages of expertise development, what differentiates a novice from an expert, and how the development and differences impact how we teach our classes or design the curriculum. This paper will also address the downside of expertise and discuss the importance of teaching expertise relative to domain expertise. Summary: Experts develop through years of experience and by progressing from novice, advance beginner, proficient, competent, and finally expert. These stages are contingent on progressive problem solving, which means individuals must engage in increasingly complex problems, strategically aligned with the learner's stage of development...

Using a mathematical model of the number dynamics in a population with age and sex structure, the relationships were studied between the number of newborns and that of mature females and males. In addition, we studied transitions between different modes of population dynamics which were dependent on changes in not only the population parameters, such as reproduction intensity, survival, and self-regulation, but also in mating pair formation. Population dynamics was found to manifest multistability; i.e., the alternative dynamics modes were observed at the same values of the population parameters but under different initial conditions...

Background Results of behavioral weight-loss treatments vary widely, with mostly unsuccessful outcomes beyond the short term. Women with obesity participating in a new cognitive-behavioral weight-loss treatment were assessed on their responses to psychological targets. Methods Groups of responders ( n = 43) and nonresponders ( n = 48) were established post hoc. Results Age, race/ethnicity, education, income, body composition, physical activity, and eating behaviors at baseline were not discriminated between responders and nonresponders...

PURPOSE: Several genetic regulators belonging to AraC family are involved in the emergence of MDR isolates of E. aerogenes due to alterations in membrane permeability. Compared with the genetic regulator Mar, RamA may be more relevant towards the emergence of antibiotic resistance. METHODOLOGY: Focusing on the global regulators, Mar and Ram, we compared the amino acid sequences of the Ram repressor in 59 clinical isolates and laboratory strains of E. aerogenes. Sequence types were associated with their corresponding multi-drug resistance phenotypes and membrane protein expression profiles using MIC and immunoblot assays...

BACKGROUND: Individuals who are particularly vulnerable to the influence of alcohol advertising, such as youth, need special protections, yet little research has been done to determine if other vulnerable groups exist. Secondary data analysis was conducted to determine if perceptions of alcohol advertising differ between groups based on their alcohol use and whether the definition of "vulnerable" should be expanded beyond demographic categories. METHODS: Students (n = 326) from 2 U...

Research suggests that the relationship between alcohol use and intimate partner violence (IPV) is moderated by a range of other factors. Therefore, we investigated the relationship between alcohol use, hostile sexism, and religious self-regulation with perpetration. Using a national sample of 255 men, we found that hostile sexism was associated with physical violence toward a partner and alcohol use was positively associated with psychological abuse toward a partner. With regard to religious self-regulation, we found that introjected religious self-regulation was positively associated with hostile sexism and positively associated with perpetrating physical IPV...

Although the antibacterial performances of emerging nanoparticles (NPs) have been extensively explored in the nitrifying systems, the impacts of dissolved oxygen (DO) levels on their bio-toxicities to the nitrifiers and the impaired cells' recovery potentials have seldom been addressed yet. In this study, the physiological and transcriptional responses of the typical ammonia oxidizers - Nitrosomonas europaea in a chemostat to the chronic ZnO NP exposure under different DO conditions were investigated. The results indicated that the cells in steady-growth state in the chemostat were more persevering than batch cultured ones to resist ZnO NP stress despite the dose-dependent NP inhibitory effects were observed...

Neurofeedback relying on functional magnetic resonance imaging (fMRI-nf) heralds new prospects for self-regulating brain and behavior. Here we provide the first comprehensive review of the fMRI-nf literature and the first systematic database of fMRI-nf findings. We synthesize information from 99 fMRI-nf experiments-the bulk of currently available data. The vast majority of fMRI-nf findings suggest that self-regulation of specific brain signatures seems viable; however, replication of concomitant behavioral outcomes remains sparse...

OBJECTIVE: Values are often phrased as ideals that people seek to approach, but they can also be conceptualized as counter-ideals that people seek to avoid. We aimed to test whether individuals endorse more strongly values that are framed in line with their predominant self-regulatory motivation, using individual difference scales in promotion/prevention (Higgins, 1997) and in behavioral approach/inhibition (Carver & White, 1994). To address this systematically, we developed approach- and avoidance-framed versions of the Portrait Value Questionnaire-RR (PVQ-RR; Schwartz et al...
