Approach-avoidance paradigms create a competition between appetitive and aversive contingencies and are widely used in nonhuman research on anxiety. Here, we examined how instructions about threat and avoidance impact control by competing contingencies over human approach-avoidance behavior. Additionally, Experiment 1 examined the effects of threat magnitude (money loss amount) and avoidance cost (fixed ratio requirements), whereas Experiment 2 examined the effects of threat information (available, unavailable and inaccurate) on approach-avoidance...

Respiratory problems and posttraumatic stress disorder (PTSD) are the signature health consequences associated with the September 11, 2001 (9/11), World Trade Center disaster and frequently co-occur. The reasons for this comorbidity, however, remain unknown. Anxiety sensitivity is a transdiagnostic trait that is associated with both PTSD and respiratory symptoms. The present study explored whether anxiety sensitivity could explain the experience of respiratory symptoms in trauma-exposed smokers with PTSD symptoms...

OBJECTIVE: To assess the association between pre-eclampsia severity and biochemical and ultrasonography markers. METHODS: A retrospective study was undertaken of women with severe pre-eclampsia (group 1, n=90), mild pre-eclampsia (group 2, n=90), or a normal pregnancy (group 3, n=90) who attended a hospital in Egypt in October 2013-April 2015. Associations between pre-eclampsia and biochemical, cardiotocography, and ultrasonography markers were investigated. RESULTS: There were significant differences between the groups in C-reactive protein (331...

OBJECTIVE: This article investigated whether work-to-family conflict (WFC) and work-to-family enrichment (WFE) were associated with employee sleep quality. WFC and WFE reflect the potential for experiences at work to negatively and positively influence nonworking life respectively, and may have implications for sleep quality. In this article, we examined whether WFC and WFE were linked with sleep quality via hedonic balance (i.e., positive affect relative to negative affect). PARTICIPANTS: The sample included 3,170 employed Australian parents involved in the Household Income and Labour Dynamics in Australia (HILDA) Survey...

Plants have evolved complex molecular, cellular, and physiological mechanisms to respond to environmental stressors. Due to the inherent complexity of this response, genetic manipulation to substantially improve water deficit tolerance, particularly in agricultural crops, has been largely unsuccessful, as the improvements are frequently accompanied by slower growth and delayed reproduction. Here, we ectopically express two abiotic stress responsive bZIP AREB/ABF transcription factor orthologs, Arabidopsis ABF3 and a Gossypium hirsutum ABF2D, in G...

BACKGROUND: Prenatal complications are associated with poor outcomes in the offspring. Access to medical records is limited in the United States and investigators often rely on maternal report of prenatal complications. STUDY DESIGN AND AIMS: We tested concordance between maternal recall and birth records in a community-based sample of mothers participating in a longitudinal study in order to determine the accuracy of maternal recall of perinatal complications. SUBJECTS: Participants were 151 biological mothers, who were interviewed about gestational age at birth, birthweight, and the most commonly occurring birth complications: nuchal cord and meconium aspiration when the female child was on average 6years old, and for whom birth records were obtained...

These longitudinal studies in older adults targeted mediated relationships between habit and physical activity (PA). In The Netherlands two independent studies were conducted among 1976 (Study 1: Mage=63.63, SD=8.66, 30% functional limitations) and 2140 (Study 2: Mage=62.75, SD=8.57, 45% functional limitations) adults aged 50 years or older. Cross-lagged panel designs were applied to examine whether habit mediates the relationship between prior and later PA and whether PA simultaneously mediates the relationship between prior and later habit...

Although experts have noted that adolescent athletes should be educated about concussions to improve their safety, there is no agreement on the most effective strategy to disseminate concussion education. The purpose of this study was to develop, implement and assess a concussion education programme. More precisely, four interactive oral presentations were delivered to high school student-athletes (N = 35, Mage = 15.94, SD = 0.34) in a large urban centre. Participants completed a questionnaire at three time-points during the season to measure changes in their knowledge (CK) and attitudes (CA) of concussions, and focus group interviews were conducted following the concussion education programme...

STUDY QUESTION: Is the molecular profile of human spermatogonia homogeneous or heterogeneous when analysed at the single-cell level? SUMMARY ANSWER: Heterogeneous expression profiles may be a key characteristic of human spermatogonia, supporting the existence of a heterogeneous stem cell population. WHAT IS KNOWN ALREADY: Despite the fact that many studies have sought to identify specific markers for human spermatogonia, the molecular fingerprint of these cells remains hitherto unknown...

BACKGROUND: Geographic proximity to health facilities is a known determinant of access to maternal care. Methods of quantifying geographical access to care have largely ignored the impact of precipitation and flooding. Further, travel has largely been imagined as unimodal where one transport mode is used for entire journeys to seek care. This study proposes a new approach for modeling potential spatio-temporal access by evaluating the impact of precipitation and floods on access to maternal health services using multiple transport modes, in southern Mozambique...

Mobile games such as Pokémon Go have become a major form of entertainment, and yet little is known about why people play the games and how their motives associate with well-being. Although literature on motives for playing video and online games is informative, the findings may not reflect the full spectrum of mobile gaming motives due to some unique affordances of mobile games (e.g., mobility). To catch up with the evolving gaming context, a popular mobile game, Pokémon Go, was taken as an example to explore individuals' mobile gaming motives...

Smoking and drinking frequently co-occur. For example, alcohol use is associated with smoking lapses during quit attempts. However, little is known regarding psychological factors explaining drinking among smokers. Anxiety sensitivity is a risk factor associated with hazardous drinking and drinking to cope and/or conform, although little is known about mechanisms underlying such associations. One potential explanatory factor is emotion dysregulation. The current study examined emotion dysregulation as an explanatory factor underlying Anxiety Sensitivity and 5 alcohol-related outcomes: hazardous drinking, alcohol consumption, alcohol problems, coping-oriented drinking, and drinking to conform...

The primary goal of the current study was to test whether parent and adolescent preference for a common language moderates the association between parenting and rank-order change over time in offspring substance use. A sample of Mexican-origin 7th-grade adolescents (Mage = 12.5 years, N = 194, 52% female) was measured longitudinally on use of tobacco, alcohol, and marijuana. Mothers, fathers, and adolescents all reported on consistent discipline and monitoring of adolescents. Both consistent discipline and monitoring predicted relative decreases in substance use into early adulthood but only among parent-offspring dyads who expressed preference for the same language (either English or Spanish)...

The current study examined parent heart rate (HR) dynamic changing patterns and their links to observed negative parenting (i.e., emotional unavailability and psychological control) during a parent-child conflict resolution task among 150 parent-child dyads (child age ranged from 6 to 12 years, Mage = 8.54 ± 1.67). Parent HR was obtained from electrocardiogram (ECG) data collected during the parent-child conflict resolution task. Negative parenting was coded offline based on the video recording of the same task...

Contextual influences on talent development (e.g., birthplace effects) have become a topic of interest for sport scientists. Birthplace effects occur when being born in a certain city size leads to participation or performance advantages, typically for those born in smaller or mid-sized cities. The purpose of this study was to investigate birthplace effects in Portuguese volleyball players by analysing city size, as well as population density - an important but infrequently used variable. Participants included 4062 volleyball players (Mage = 33), 53...

BACKGROUND: Pancreatic adenocarcinoma (PDAC) is now the third leading cause of cancer mortality in the United States. More than 80% of patients present with distant metastasis precluding surgical eligibility. Even among patients with localized disease deemed eligible for surgical resection, the median survival is only 22.8 months due to high recurrence rates. Identification of a biomarker correlated with patient specific prognosis upon initial diagnosis can serve as a way to individualize treatment options...

The reinforcing value of food is an important determinant of food intake. Research has yet to examine the relative reinforcing value (RRV) of snack foods in young children with overweight and obesity (OW/OB). The current study compared the RRV of high-energy dense foods (cookies) to low-energy dense foods (fruits) between preschoolers with OW/OB and healthy weight (HW). RRV of cookies and fruits in preschoolers with OW/OB (n = 30; Mage = 4.4 ± 0.84; 60% male) and HW (n = 30; Mage = 4.5 ± 0.85; 70% male) was assessed with a developmentally-tailored computer program which used a progressive fixed ratio reward schedule...

Anhedonia is a major public health concern and has proven particularly difficult to counteract. It has been hypothesized that anhedonia can be deterred by engagement in rewarding social and physical events. The aims of the present study were to examine (1) the effects of personalized lifestyle advice based on observed individual patterns of lifestyle factors and experienced pleasure in anhedonic young adults; and (2) whether a tandem skydive can enhance the motivation to carry out the recommended lifestyle changes...
