Previous research has shown that a subpopulation of cells within cultured human dermal fibroblasts, termed multilineage-differentiating stress enduring (Muse) cells, are preferentially reprogrammed into induced pluripotent stem cells. However, controversy exists over whether these cells are the only cells capable of being reprogrammed from a heterogeneous population of fibroblasts. Similarly, there is little research to suggest such cells may exist in embryonic tissues or other species. In order to address if such a cell population exists in pigs, we investigated porcine embryonic fibroblast populations (pEFs) and identified heterogeneous expression of several key cell surface markers...

Child health and developmental outcomes are influenced by the health of the family and the context created. Research suggests symptoms of poor family health (e.g. suboptimal family interactions, parenting stress) yet there is limited understanding of the factors which contribute to robust family health which may unveil opportunities for targeted intervention and family health promotion. The present study examined families' experiences of family health and factors contributing to family health. We performed a qualitative study using constructivist grounded theory methods to guide our understanding of family health for families with typically developing children aged 5-18...

PURPOSE: Few studies have assessed how sexual and gender minority stigmas affect the mental health of trans women and self-identified men who have sex with men (MSM) in India, populations with a high HIV burden. We tested whether social support and resilient coping act as mediators of the effect of sexual and gender minority stigmas on depression as proposed by Hatzenbuehler's psychological mediation framework, or as moderators based on Meyer's minority stress theory. METHODS: We conducted a cross-sectional survey among trans women (n = 300) and MSM (n = 300) recruited from urban and rural sites in India...

OBJECTIVE: In order to protect medical students from burnout and its untoward psychiatric effects, it is imperative to understand their stress, burnout, coping, and resilience experiences. This study aimed to derive collective definitions from the medical student perspective, to identify common themes of students' experiences, and to distinguish pre-clinical and clinical year students' experiences relating to these four constructs. METHODS: The authors conducted focus groups of medical students in Singapore across 4 years using a semi-structured question guide...

Working memory, used to temporarily store and mentally manipulate information, is important for children's learning. It is therefore valuable to understand which (contextual) factors promote or hinder working memory performance. Recent research shows positive associations between positive parent-child and teacher-student interactions and working memory performance and development. However, no study has yet experimentally investigated how parents and teachers affect working memory performance. Based on attachment theory, the current study investigated the role of parent and teacher emotional support in promoting working memory performance by buffering the negative effect of social stress...

Posttraumatic stress disorder (PTSD) is a clinical condition that occurs after a discrete traumatic event, such as an accident or assault. Research into PTSD has primarily been adult-focused; however, there is a growing body of evidence evaluating the theory and treatment of PTSD in young children. Consequently, cognitive behavior therapy (CBT) interventions for PTSD in youth have been developed that focus on 3 core components of the cognitive model-a disorganized memory of the trauma, maladaptive appraisals of the trauma and its effects (meanings), and dysfunctional coping mechanisms (management)...

BACKGROUND: Chronic tinnitus (phantom perception of sound) significantly disrupts quality of life in 15-20% of those who experience it. Understanding how certain personality traits impact tinnitus perception and distress can be beneficial for the development of interventions to improve the lives of tinnitus sufferers. PURPOSE: Four key self-reported personality traits (social closeness, stress reaction, alienation, and self-control) were identified from previous research as being associated with tinnitus...

PURPOSE: Border-Crossing theory suggests work-life balance and career satisfaction are inter-related and disappointment in work-life balance may predict changes in one's career path. Application of this theory to health profession faculty is plausible but has not been fully explored. The purpose of this study is to examine factors related to reported career change intention among United States pharmacy school faculty and to determine if Border-Crossing theory fits these observations. METHODS: Results from a national web-based survey administered via Qualtrics(®) to American Association of Colleges of Pharmacy (AACP) members were utilized...

The elastic moduli of a transversely isotropic model granular material, made of slightly polydisperse elastic-frictional spherical beads, in equilibrium along a one-dimensional (oedometric) compression path, as described in the companion paper [M. H. Khalili et al., Phys. Rev. E 95, 032907 (2017)]10.1103/PhysRevE.95.032907, are investigated by numerical simulations. The relations of the five independent moduli to stresses, density, coordination number, fabric and force anisotropies are studied for different internal material states along the oedometric loading path...

In recent work it was clarified that amorphous solids under strain control do not possess nonlinear elastic theory in the sense that the shear modulus exists but nonlinear moduli exhibit sample-to-sample fluctuations that grow without bound with the system size. More relevant, however, for experiments are the conditions of stress control. In the present Rapid Communication we show that also under stress control the shear modulus exists, but higher-order moduli show unbounded sample-to-sample fluctuation. The unavoidable consequence is that the characterization of stress-strain curves in experiments should be done with a stress-dependent shear modulus rather than with nonlinear expansions...

J S Langer
The statistical-thermodynamic dislocation theory developed in previous papers is used here in an analysis of yielding transitions and grain-size effects in polycrystalline solids. Calculations are based on the 1995 experimental results of Meyers, Andrade, and Chokshi [Metall. Mater. Trans. A 26, 2881 (1995)MMTAEB1073-562310.1007/BF02669646] for polycrystalline copper under strain-hardening conditions. The main assertion is that the well-known Hall-Petch effects are caused by enhanced strengths of dislocation sources at the edges of grains instead of the commonly assumed resistance to dislocation flow across grain boundaries...

Pu Wang, Zhen Huang
This paper uses experimental investigation and theoretical derivation to study the unified failure mechanism and ultimate capacity model of reinforced concrete (RC) members under combined axial, bending, shear and torsion loading. Fifteen RC members are tested under different combinations of compressive axial force, bending, shear and torsion using experimental equipment designed by the authors. The failure mechanism and ultimate strength data for the four groups of tested RC members under different combined loading conditions are investigated and discussed in detail...

OBJECTIVE: We applied self-determination theory to examine a model whereby perceived parental autonomy support directly and indirectly affects nonsuicidal self-injury (NSSI) through difficulties in emotion regulation. METHOD: 639 participants (53% female) with a mean age of 13.38 years (SD = 0.51) completed the How I Deal with Stress Questionnaire as a screener for NSSI, the Perceptions of Parents Scale, and the Difficulties in emotion Regulation Scale. Participants who indicated having ever hurt themselves on purpose without the intent to die (n = 116, 66% female) were classified in the NSSI lifetime group...

In this study, two kinds of Au-coated gratings (ACGs) with a period of 1740 lines/mm were fabricated and evaluated. For these ACG samples, magnetron sputtering and e-beam evaporation were used as the gold deposition process, and the samples had a bandwidth of at least 170 nm, with the -1st-order diffraction efficiency exceeding 90% around the center wavelength of 800 nm. The one-on-one damage threshold of ACGs fabricated by magnetron sputtering and e-beam evaporation measured at a pulse width of 60 fs was 0...

Parental empathy is a key component of sensitive parenting that supports children's social adaptation throughout life. Consistent with a two dissociable network perspective on empathy, we measured within- and between-network integrity of two empathy-related networks in the parental brain as predictors of children's social outcomes across the first six years of life. We focused on two empathy networks; embodied simulation, which supports parents' capacity to resonate with infant state and emotions and implicates cingulo-insulary structures, and mentalizing, which underpins parents' theory-of-mind and mental attributions via prefrontal-temporo-parietal circuit...

Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy that causes systolic heart failure (HF) in previously healthy young women. Despite latest remarkable achievement, unifying pathophysiologic mechanism is not well established. Considering close temporal relationship to pregnancy, the recent prolactin theory is promising. Abnormal short form of 16-kDa prolactin may be produced in the oxidative stress milieu, show anti-angiogenic effect and damage cardiovascular structure in late pregnancy. Future study is needed to determine whether abnormal prolactin system is useful as a biomarker for diagnosis and therapy of PPCM...

Fluoride is a common element in nature and our daily life, and excessive intake of this element can cause fluorosis and irreversible brain damage. The toxic effects of fluoride on the central nervous system may be attributed to the release of inflammatory cytokines and ROS. GSK3β is a key protein that modulates NF-κB activity and inflammatory cytokine levels and plays an important role in the Wnt signaling pathway. In this study, we found that fluoride altered the inflammatory status and oxidative stress by inhibiting Wnt signaling pathway activity...

Classical old-field succession studies focused on vegetation changes after the abandonment of annual croplands or on succession after the elimination of cultivated crops. Perennial-crop-mediated succession, where fields are initially covered by perennial crops, reveals alternative aspects of old-field succession theories. We tested the validity of classical theories of old-field succession for perennial-crop-mediated succession. We formulated the following hypotheses: (1) functional diversity increases with increasing field age; (2) resource acquisition versus conservation trade-off shifts toward conservation at community level during the succession; (3) the importance of spatial and temporal seed dispersal decreases during the succession; and (4) competitiveness and stress-tolerance increases and ruderality decreases at community level during the succession...

Self-efficacy for coping with cancer is a specific construct that refers to behaviors that occur in the course of dealing with a cancer diagnosis, cancer treatments, and transitioning to survivorship. One of the more widely used measures of self-efficacy for coping strategies with cancer is the Cancer Behavior Inventory. The following general questions provide a framework for this research: 1. Is self-efficacy for coping with cancer related to distress and quality of life of a cancer patient?. 2. Do self-efficacy for coping with cancer and the target psychological outcomes (i...

Parental care results in increased hippocampal volumes through adaptive stress responses in developing animals. However, human studies have not yet provided consistent findings analogous to the animal literature, possibly because parental care in humans is likely intermingled with parental overprotection, as suggested by the optimal parenting theory. Here, we tested the hypothesis that the effect of parental care on offspring hippocampal volume varies as a function of parental overprotection with a large cohort of young adult participants (N = 257)...
