OBJECTIVE: The novel concept of "the trauma therapists" journey' during their work with formerly tortured refugees and asylum seekers is introduced, mapped, and explicated for a convenience sample of 10 psychological therapists/practitioners who work in the United Kingdom. METHOD: This study operationalized semistructured interviews that were focused on therapists' experiences of providing trauma psychotherapy to sanctuary seekers who presented to a range of psychological therapy services...

BACKGROUND: Childhood sexual abuse (CSA) is a significant risk factor with consistently demonstrated negative implications for satisfaction with adult romantic relationships. Yet, research on risk and protective factors in this context is scarce, particularly among well-functioning adults. OBJECTIVE: Addressing this gap, the present study focused on the potential mediating and moderating roles of mentalizing or reflective functioning, i.e., the capacity to understand oneself and others in terms of intentional mental states...

OBJECTIVE: To test potential cognitive and interpersonal moderators of two evidence-based youth depression prevention programs. METHOD: Two hundred four adolescents ( M age = 14.62 years, SD = 1.65; 56% female; 71% White, 11% Black, 11% multiracial, 5% Asian, 2% other races, 18% Hispanic/Latinx) were randomized to either a cognitive-behavioral (Coping With Stress [CWS]) or interpersonal (Interpersonal Psychotherapy-Adolescent Skills Training [IPT-AST]) prevention program...

We investigate, using a recently developed model of liquid state theory describing the rheology of dense granular flows, how a yield stress appears in granular matter at the yielding transition. Our model allows us to predict an analytical equation of the corresponding dynamical yield surface, which is compared to the usual models of solid fracture. In particular, this yield surface interpolates between the typical failure behaviors of soft and hard materials. This work also underlines the central role played by the effective friction coefficient at the yielding transition...

This paper presents a novel approach for designing a fail-safe bending-resistant structure from the combination of explicit discrete component-based topology optimization and the porcupine quill-inspired features. To achieve fail-safe functionalities under classical topology optimization formulations, the method involves constructing discrete components at various scales to imitate the quill's foam-like characteristics. The components are iteratively updated, and the optimization process allows for the grading of quill-inspired features while achieving optimal structural compliance under bending loads...

Hearing loss (HL) is a health burden that seriously affects the quality of life of cancer patients receiving platinum-based chemotherapy, and few FDA-approved treatment specifically targets this condition. The main mechanisms that contribute to cisplatin-induced hearing loss are oxidative stress and subsequent cell death, including ferroptosis revealed by us as a new mechanism recently. In this study, we employed the frontier molecular orbital (FMO) theory approach as a convenient prediction method for the glutathione peroxidase (GPx)-like activity of isoselenazolones and discovered new isoselenazolones with great GPx-like activity...

In this paper, a two-dimensional (2D) thermo-hydro-mechanical dynamic (THMD) coupling analysis in the presence of a half-space medium is studied using Ezzat's fractional order generalized theory of thermoelasticity. Using normal mode analysis (NMA), the influence of the anisotropy of the thermal conduction coefficient, fractional derivatives, and frequency on the THMD response of anisotropy, fully saturated, and poroelastic subgrade is then analyzed with a time-harmonic load including mechanical load and thermal source subjected to the surface...

Background: Imagery rescripting (ImRs) has shown to be an effective treatment for posttraumatic stress disorders (PTSD) resulting from childhood-related trauma. The current theory is that the change of meaning of the trauma memory is central to the treatment. Several authors have suggested that the expression of needs, feelings and actions may act as potential healing factors, but little specific research aimed at (in)validating this hypothesis has been done so far. Objective: In this study we investigated to what extent the expression of inhibited action tendencies and the fulfilling of needs lead to the reduction of PTSD symptoms in clients with early childhood trauma...

BACKGROUND: Ferroptosis is an iron-dependent regulating programmed cell death discovered recently that has been receiving much attention in traumatic brain injury (TBI). xCT, a major functional subunit of Cystine/glutamic acid reverse transporter (System Xc-), promotes cystine intake and glutathione biosynthesis, thereby protecting against oxidative stress and ferroptosis. OBJECTIVE: The intention of this research was to verify the hypothesis that electroacupuncture (EA) exerted an anti-ferroptosis effect via an increase in the expression of xCT and activation of the System Xc-/GSH/GPX4 axis in cortical neurons of TBI rats...

Susceptibility to COVID-19, the most devastating global pandemic, appears to vary widely across different population groups. Exposure to toxoplasmosis has been proposed as a theory to explain the diversity of these populations. The aim of the present study was to investigate the possible association between latent toxoplasmosis and COVID-19 and its probable correlation with markers of oxidative stress, C-reactive protein (CRP) and ferritin. In a case-control study, blood samples were collected from 91 confirmed (48 non-pneumonic; NP, and 43 pneumonic; P) COVID-19 patients and 45 healthy controls...

Health-related stigma is associated with adverse outcomes including depression, stress and reduced engagement in health behaviours which are particularly harmful in pregnancy and the postpartum. Women with gestational diabetes mellitus (GDM) report negative psychosocial experiences and may be at risk of stigma related to the condition. We aimed to understand women's experiences of GDM-specific stigma. Individual interviews were conducted with n = 53 women living in the UK with a current or past (within 4 years) GDM...

BACKGROUND: Childhood maltreatment (CM) is associated with neurobiological aberrations and atypical social cognition. Few studies have examined the neural effects of another common early-life interpersonal stressor, namely peer victimisation (PV). This study examines the associations between tract aberrations and childhood interpersonal stress from caregivers (CM) and peers (PV), and explores how the observed tract alterations are in turn related to affective theory of mind (ToM). METHODS: Data from 107 age-and gender-matched youths (34 CM [age = 19...

The cyanobacterium Synechococcus elongatus PCC 7942 holds significant potential as a biofactory for recombinant protein (RP) production due to its capacity to harness light energy and utilize CO2 . This study aimed to enhance RP production by integration of native promoters and magnetic field application (MF) in S. elongatus PCC 7942. The psbA2 promoter, which responds to stress conditions, was chosen for the integration of the ZsGreen1 gene. Results indicated successful gene integration, affirming prior studies that showed no growth alterations in transgenic strains...

A prototypical thiolate (RS)-protected gold cluster [Au25 (SR)18 ]- has high stability due to specific geometric and electronic structures: an icosahedral ( I h ) Au13 core with a closed electronic shell containing eight electrons is completely protected by six units of Au2 (SR)3 . Nevertheless, collisional excitation of [Au25 (SR)18 ]- in a vacuum induces the sequential release of Au4 (SR)4 to form [Au21 (SR)14 ]- and [Au17 (SR)10 ]- both containing eight electrons. To answer a naive question of whether these fragments bear an I h Au13 (8e) core, the geometrical structures of [Au21 (SC3 H7 )14 ]- and [Au17 (SC3 H7 )10 ]- in the gas phase were examined by the combination of anion photoelectron spectroscopy and density functional theory (DFT) calculation of simplified models of [Au21 (SCH3 )14 ]- and [Au17 (SCH3 )10 ]- ...

The organization of water molecules and ions between charged mineral surfaces determines the stability of colloidal suspensions and the strength of phase-separated particulate gels. In this article, we assemble a density functional that measures the free energy due to the interaction of water molecules and ions in electric double layers. The model accounts for the finite size of the particles using fundamental measure theory, hydrogen-bonding between water molecules using Wertheim's statistical association theory, long-range dispersion interactions using Barker and Henderson's high-temperature expansion, electrostatic correlations using a functionalized mean-spherical approximation, and Coulomb forces through the Poisson equation...

Technostress is a rising issue in the changing world of digital work. Technostress can cause severe adverse outcomes for individuals and organizations. Thus, organizations face the moral, legal, and economic responsibility to prevent employees' excessive technostress. As technostress develops over time, it is crucial to prevent it throughout the process of its emergence instead of only reacting after adverse outcomes occur. Contextualizing the Theory of Preventive Stress management to technostress, we synthesize and advance existing knowledge on inhibiting technostress...

INTRODUCTION: Following the conservation of resource theory and natural stress reduction theory, the current study investigated mediated pathways, reverse mediated pathways, and reciprocal pathways between connectedness to nature, depressive symptoms, and adolescent learning burnout via a half-longitudinal analysis, and discussed gender differences in the three models. METHODS: Two waves of data were collected in December 2022 (T1) and June 2023 (T2) for this study...

BACKGROUND: The global campaign for "Undetectable equals Untransmittable" (U = U) seeks to spread awareness of HIV treatment as prevention, aiming to enhance psychological well-being and diminish stigma. Despite its potential benefits, U = U faces challenges in Sub-Saharan Africa, with low awareness and hesitancy to endorse it. We sought to develop a U = U communications intervention to support HIV counselling in primary healthcare settings in South Africa...

In the context of the COVID-19 pandemic, university students were exposed to increased stress, which significantly affected their well-being. This study examines the coping mechanisms employed by Chinese university students during this crisis, with a particular focus on the potential protective role of coping flexibility in maintaining their well-being. Using the transactional stress model and the dual-process theory of coping flexibility, this longitudinal study analyzed the responses of 206 Chinese university students at three measurement points in late 2022...

OBJECTIVE: Sexual minority men experience disproportionately elevated rates of skin cancers, likely driven by excess ultraviolet radiation exposure-namely through tanning behaviors. However, limited integrated theoretical models exist to explain sexual minority men's elevated skin cancer risk. The aim of the current study is to further test and refine an integrated theory of skin cancer risk behaviors among sexual minority men by incorporating minority stress into the integrated health behavior model of tanning...
