Sleep is a basic biological process supporting emotion regulation. The emotion regulation function of sleep may be particularly important in the context of chronic stress. To better understand how chronic stress and sleep interact to predict mood, 66 parents of children with autism completed daily diaries assessing parenting stress, negative mood, and sleep quality for 6 consecutive days. Hierarchical linear modelling revealed that daily negative mood was predicted by between-person differences in parenting stress and between-person differences in sleep efficiency...

β-Ti alloys have attracted considerable attention as new biomedical shape memory alloys. Given the critical importance of the plastic deformation in the martensite phase for the shape memory effect and superelasticity, we investigated here the plastic deformation behaviour of a single crystal of α″ (orthorhombic) martensite of Ti-27 mol%Nb shape memory alloy obtained by the stress-induced martensitic transformation of a single crystal of the parent β phase. Four operative plastic deformation modes were observed, including two dislocation slips and two twinnings...

We have previously established that mitochondrial Complex I (CI) mutants of Candida albicans display reduced oxygen consumption, decreased ATP production, and increased reactive oxidant species (ROS) during cell growth. Using the Seahorse XF96 analyzer, the energetic phenotypes of Electron Transport Chain (ETC) complex mutants are further characterized in the current study. The underlying regulation of energetic changes in these mutants is determined in glucose and non-glucose conditions when compared to wild type (WT) cells...

Introduction Quality of life (QOL) is significantly impaired among individuals with post-traumatic stress disorder (PTSD); however, few treatment outcome studies examine QOL following treatment. Furthermore, the use of videoconferencing to deliver evidence-based treatments for PTSD is increasing dramatically. Although videoconferencing has demonstrated non-inferiority to in-person treatment modalities for improving PTSD symptom severity, no studies to date have directly compared QOL outcomes of an evidence-based intervention delivered via videoconferencing to one delivered in-person...

STUDY QUESTION: Are there differences in levels of parental wellbeing (parental stress, psychological adjustment and partner relationship satisfaction) between gay-father families with infants born through surrogacy, lesbian-mother families with infants born through donor insemination, and heterosexual-parent families with infants born through IVF? SUMMARY ANSWER: There were no differences in parental wellbeing. WHAT IS KNOWN ALREADY: The only other study of parental wellbeing in gay-father families formed through surrogacy (mean age children: 4 years old) found no difference in couple relationship satisfaction between these families and lesbian-mother families formed through donor insemination and heterosexual-parent families formed without assisted reproductive technologies...

It has been suggested that children that are exposed to a stressful environment at home have an increased susceptibility for air pollution-related asthma. The aim here was to investigate the association between air pollution exposure and asthma, and effect modification by mental health and by socio-economic status (as markers of a stressful environment). All individuals under 18 years of age in four Swedish counties during 2007 to 2010 (1.2 million people) were included. The outcome was defined as dispensing at least two asthma medications during follow up...

BACKGROUND: Supporting early mother-infant relationships to ensure infants' future health has been recommended. The aim of this study was to investigate whether video feedback using the Marte Meo method promotes a healthy early relationship between infants and vulnerable first-time mothers. Video feedback or usual care was delivered by health visitors during home visits in Danish municipalities. METHODS: This quasi-experimental study included pre- and post-tests of 278 vulnerable families...

We studied the connection between the structural relaxation and viscosity for a binary model of repulsive particles in the supercooled liquid regime. The used approach is based on the decomposition of the macroscopic Green-Kubo stress correlation function into the correlation functions between the atomic level stresses. Previously we used the approach to study an iron-like single component system of particles. The role of vibrational motion has been addressed through the demonstration of the relationship between viscosity and the shear waves propagating over large distances...

BACKGROUND: Because very large numbers of single nucleotide polymorphisms (SNPs) are now available throughout the genome, they are particularly suitable for the detection of genomic regions where a reduction in heterozygosity has occurred and they offer new opportunities to improve the accuracy of inbreeding ([Formula: see text]) estimates. Runs of homozygosity (ROH) are contiguous lengths of homozygous segments of the genome where the two haplotypes inherited from the parents are identical...

The early environment has a major impact on the developing embryo, fetus and infant. Parental adversity (maternal and paternal) and glucocorticoid exposure prior to conception and during pregnancy have profound effects on the development and subsequent function of the hypothalamic-pituitary-adrenal (HPA) axis and related behaviours. These effects are species-, sex- and age-specific, and depend on the timing and duration of exposure. The impact of these early exposures can extend across multiple generations, via both the maternal and paternal lineage, and recent studies have begun to determine the mechanisms by which this occurs...

Microparticles (MP) are plasmic membrane fragments released from cells after physiological stimulation or stress conditions like inflammation or infection. Their production is correlated to the rate of cell apoptosis. All types of cells can produce MP but they are produced mainly by platelets, endothelial cells, and leukocytes. They carry many bio-active molecules on their surface, specific to the parental cell, giving them the ability to be biomarkers and bio-effectors. MP are present in circulating blood, tissues and many biological fluids...

Symptoms of posttraumatic stress disorder (PTSD) and major depressive disorder are the most frequently co-occurring problems following potentially traumatic events. It is unclear whether these comorbidities represent two correlated but distinct disorders or a common post-event response. We sought to inform this question by examining the distinctiveness of PTSD and depression symptoms at four cross-sectional time points, using data from a parent prospective longitudinal study of 858 Marines evaluated before deployment and approximately 1, 5, and 8 months after returning from the Afghanistan war...

Five randomized controlled trials have shown that child-parent psychotherapy (CPP) improves trauma symptoms in children. Less is known about parent symptoms or moderators of symptom change. In a sample of 199 parent (81% biological mother; 54% Latina/o) and child (aged 2 to 6 years; 52% male; 49% Latina/o) dyads who participated in an open treatment study of CPP, this study investigated whether parent and child symptoms similarly decreased during treatment and whether improvement was moderated by parent, child, and treatment characteristics...

There has been increased focus on the use of family-centred care interventions, such as skin-to-skin contact (SSC) in Neonatal Intensive Special Care (NISC) Units over the past two decades. SSC between a parent and their neonate has previously shown to promote positive mental and emotional health in parents and assist in bonding and attachment between parent and neonate. The purpose of this study was to investigate the effect that SSC between parent and their neonate has on the parent's heart rate (HR) and blood pressure (BP)...

OBJECTIVES: Enhanced mitochondrial fatty acid utilization is known to increase radical oxidative stress and induce insulin resistance. An increased level of plasma acylcarnitine (AC) has been proposed to indicate mitochondrial energy substrate overload, a possible mechanism leading to insulin resistance. The aim of our study was to determine fasting and postprandial plasma acetyl-carnitine (AC2:0), palmitoyl-carnitine (AC16:0), oleoyl-carnitine (AC18:1) and linoleoyl-carnitine (AC18:2) levels and their relationships with plasma nonesterified fatty acid appearance and oxidation rates and insulin sensitivity in participants with type 2 diabetes and normoglycemic offspring of 2 parents with type 2 diabetes (FH+) compared to healthy participants without family histories of type 2 diabetes (FH-)...

INTRODUCTION: Surgical procedures involve traumatic stress. Children may develop chronic psychological distress and dysfunction after surgery, with consequent reluctance to comply with medical follow-up care. A literature review of this topic shows that it has been understudied. Our study aims to assess the frequency and characteristics of symptoms of persistent psychological distress in children following surgery, which have not been documented before, in order to promote its awareness and its early identification...

In this study, we investigated the mediating effect of social support on the relationship between parenting stress and life satisfaction in Chinese mothers of children with cerebral palsy ( N = 369). The results showed that family support and friend support, but not significant-other support, had mediating effects on the relationship between parenting stress and life satisfaction. Moreover, the mediating effect of friend support was equal to family support. These results suggest that the focus should be on reducing parenting stress and increasing support from family and friends to help improve life satisfaction in mothers of children with cerebral palsy...

Leaf rust (Puccinia triticina) is a major biotic stress affecting wheat yields worldwide. Host-plant resistance is the best method for controlling leaf rust. Aegilops speltoides is a good source of resistance against wheat rusts. To date, five Lr genes, Lr28, Lr35, Lr36, Lr47, and Lr51, have been transferred from Ae. speltoides to bread wheat. In Selection2427, a bread wheat introgresed line with Ae. speltoides as the donor parent, a dominant gene for leaf rust resistance was mapped to the long arm of chromosome 3B (LrS2427)...
