BACKGROUND: Depression is a common mental health outcome after traumatic injury, negatively impacting physical outcomes and increasing the cost of care. Research shows that the presence and quality of support is a leading protective factor against depression post-injury; however, research is vague on the directional effects of both factors over the course of recovery. METHODS: 130 patients admitted to a Level I Trauma Center were recruited to a prospective study examining overall outcomes one-year after injury...

Metal-organic frameworks (MOFs) deposited from solution have the potential to form 2-dimensional supramolecular thin films suitable for molecular electronic applications. However, the main challenges lie in achieving selective attachment to the substrate surface, and the integration of organic conductive ligands into the MOF structure to achieve conductivity. The presented results demonstrate that photoemission spectroscopy combined with preparation in a system-attached glovebox can be used to characterize the electronic structure of such systems...

In this work, the adsorption of Rhodamine 6G molecules on some graphene substrates is investigated using density functional theory. Some simple models, such as those of perfect graphene, defective graphene, *O/*OH modified graphene and B/N doping graphene, are constructed as substrates to simulate graphene oxide and B/N doping graphene sheets. It is demonstrated that the interactions of Rhodamine 6G molecules with graphene materials are strong. In particular, the amine group of Rhodamine 6G molecules can favor the formation of a chemical bond with some graphene substrates characterized by under-coordinated atoms...

Epitaxial growth of DNA functionalized nanoparticles is used to grow extended superlattices with a preferred orientation for optimizing the physical properties of meta-materials for real applications. Like any solid in nature, superlattices can contain different kinds of structural defects, which significantly alter their physical properties. Further development of these materials requires a deeper understanding of, as well as precise control over, structural defect formation. Here we use Monte Carlo simulations to conduct a systematic study of the equilibrium structures of the adsorbed nanoparticle monolayers by changing the binding energies of different attachment sites...

The existing literature has identified that beliefs about the interpersonal meaning of condom use are a significant predictor of condomless anal sex (CAS). Some have suggested that condom use in this context may function as a form of nonverbal communication. This study utilized attachment theory as a framework and tested a hypothesized model linking adult attachment to CAS through communication skills and condom expectancies. An online survey was completed by 122 single, HIV-negative gay and bisexual (GB) men living in the U...

Nowadays, issues of religiosity and spirituality are viewed differently than 50 years ago. Social upheaval, migration and secularization have changed the interpretation of religious meaning but have not made religion obsolete. This article describes the differences between a religious and a secular global view and defines spirituality as attachment to a larger entirety. The resources of spirituality are described and the dangers of fanaticism and fundamentalism should not be neglected. Criteria for healthy belief are compared to religious delusion...

In this work, we designed three dyes (Ru1, Ru2, and Ru3) by modifying the square-planar quadridentate ligand of the experimental Ru(ii) complex K1, [RuL(trans-NCS)2] with L = dimethyl-6,60-bis(methyl-2-pyridylamino)-2,20-bipyridine-4,40-dicarboxylate, from a theoretical viewpoint. As is known, K1 shows obvious advantages over the famous dye N749 in light absorption ability because of its highly conjugated ancillary ligands. Density functional theory and time-dependent density functional theory methods were used to determine the geometrical structures, electronic structures and absorption spectra of the dye complexes...

Parents of preterm infants commonly experience separation from their infant or exclusion from their role as primary caregivers during the hospital care of their infant, which may impair parent-infant bonding and parents' psychological well-being. Therefore, we developed the Close Collaboration with Parents™ intervention to improve staff skills in communicating and collaborating with parents in neonatal intensive care units (NICU), to increase parents' presence and participation into infant care, and to improve parent-infant bonding and, thereby, parents' psychological well-being and later child development...

This paper presents a systematic literature review of studies that shed light on the health of migrants in Iran from the perspective of social justice. A systematic search was conducted in PubMed and Iranian databases, including IranMedex, Magiran, and SID, in June 2012. All studies that were published until June 2012 describing the health status of migrants - including refugees - in Iran were included. The search results were categorisoyed according to an adapted version of the six dimensions of well-being in Madison Powers' and Ruth Faden's theory of social justice in health...

: The Early Maladaptive Schema Questionnaires Set for Children and Adolescents (SQS) was developed to assess early maladaptive schemas in children between the ages of 10 and 16 in Turkey. The SQS consists of five questionnaires that represent five schema domains in Young's schema theory. Psychometric properties (n = 983) and normative values (n = 2250) of SQS were investigated in children and adolescents between the ages of 10 and 16. Both exploratory and confirmatory factor analyses were performed...

Graphene oxide is one of the most studied nanomaterials owing to its huge application potential in many fields, including biomedicine, sensing, drug delivery, optical and optoelectronic technologies. However, a detailed description of the chemical composition and the extent of oxidation in graphene oxide remains a key challenge affecting its applicability and further development of new applications. Here, we report direct monitoring of the chemical oxidation of an individual graphene flake during ultraviolet/ozone treatment through in situ atomic force microscopy based on dynamic force mapping...

Carbon-centered radicals are interesting alternatives to otherwise commonly used nitroxide spin labels for dipolar spectroscopy techniques because of their narrow ESR linewidth. Herein, we present a novel BDPA biradical, where two BDPA (α,α,γ,γ-bisdiphenylene-β-phenylallyl) radicals are covalently tethered by a saturated biphenyl acetylene linker. The inter-spin distance between the two spin carrier fragments was measured using double quantum coherence (DQC) ESR methodology. The DQC experiment revealed a mean distance of only 1...

In this paper, we highlight issues we consider key to the development of an evidence-based intervention for the parents of young children who had experienced early adversity. The intervention was initially developed for foster infants, but adapted for infants living with their neglecting parents, then for young children adopted internationally, and finally for toddlers in foster care or living with neglecting birth parents. The intervention and its adaptations share a focus on the importance of providing nurturance to children when they are distressed, and following children's lead when they are not distressed...

BACKGROUND: Stroke can affect our ability to perform daily activities, although it can be difficult to identify the underlying functional impairment(s). Recent theories highlight the importance of sensory feedback in selecting future motor actions. This selection process can involve multiple processes to achieve a behavioural goal, including selective attention, feature/object recognition, and movement inhibition. These functions are often impaired after stroke, but existing clinical measures tend to explore these processes in isolation and without time constraints...

A training set of eleven X-ray structures determined for biomimetic complexes between cucurbit[n]uril (CB[7 or 8]) hosts and adamantane-/diamantane ammonium/aminium guests were studied with DFT-D3 quantum mechanical computational methods to afford ΔGcalcd binding energies. A novel feature of this work is that the fidelity of the BLYP-D3/def2-TZVPP choice of DFT functional was proven by comparison with more accurate methods. For the first time, the CB[n]⋅guest complex binding energy subcomponents [for example, ΔEdispersion , ΔEelectrostatic , ΔGsolvation , binding entropy (-TΔS), and induced fit Edeformation(host) , Edeformation(guest) ] were calculated...

The stability and reactivity of the hematite, Fe2O3(0001) surface are studied by density functional theory including an on-site Coulomb term (DFT+U). Even under oxygen rich conditions, the metal-terminated surface is shown to be stable. On this surface termination, the isolated water molecule forms a heterolytically dissociated structure with the OH(-) group attached to a surface Fe(3+) ion and the proton to a surface O(2-) ion. Dissociative adsorption is strongly enhanced at oxygen vacancy sites. Here, the OH(-) group fills the oxygen vacancy site...

We developed and tested a theoretical model for the attachment of fluid-infused porous supra-particles to a fluid-liquid interface. We considered the wetting behaviour of agglomerated clusters of particles, typical of powdered materials dispersed in a liquid, as well as of the adsorption of liquid-infused colloidosomes at the liquid-fluid interface. The free energy of attachment of a composite spherical porous supra-particle made from much smaller aggregated spherical particles to the oil-water interface was calculated...

Solar power is a strong alternative to the currently used fossil fuels in order to satisfy the world's energy needs. Among them, dye-sensitized solar cells (DSSC) represent a low-cost option. Efficient and cheap dyes are currently needed to make DSSCs competitive. Computational chemistry can be used to guide the design of new light-absorbing chromophores. Here, we have computationally studied the lowest excited states of ZnPBAT, which is a recently synthesized porphyrinoid chromophore with high light-absorption efficiency...
