Unrecognized grief - Prevalence and comorbidity of prolonged grief among refugees in Sweden.

Refugees often experience multiple losses. Despite this, and even though the loss is often due to unnatural causes and violent killings, the presence of Prolonged Grief (PG) among refugees may be obscured by other diagnoses such as depression and post-traumatic stress disorder (PTSD). In this cross-sectional study, we assessed the prevalence of PG and its comorbidity with depression and PTSD among 679 adult refugees in Sweden.

Voxel-Wise Brain Graphs From Diffusion MRI: Intrinsic Eigenspace Dimensionality and Application to Functional MRI.

Structural brain graphs are conventionally limited to defining nodes as gray matter regions from an atlas, with edges reflecting the density of axonal projections between pairs of nodes. Here we explicitly model the entire set of voxels within a brain mask as nodes of high-resolution, subject-specific graphs. We define the strength of local voxel-to-voxel connections using diffusion tensors and orientation distribution functions derived from diffusion MRI data.

Improved charge storage performance of a layered MoC MXene/MoS/graphene nanocomposite.

The construction of nanocomposite electrodes based on 2D materials is an efficient route for property enrichment and for exploitation of constituent 2D materials. Herein, a flexible MoC -MXene/MoS/graphene (MOMG) composite electrode is constructed, utilizing an environment-friendly method for high-quality graphene and MoS synthesis. The presence of graphene and MoS between MXene sheets limits the commonly observed restacking, increases the interlayer spacing, and facilitates the ionic and electronic conduction.

Resurgent Na+ Current Offers Noise Modulation in Bursting Neurons.

Neurons utilize bursts of action potentials as an efficient and reliable way to encode information. It is likely that the intrinsic membrane properties of neurons involved in burst generation may also participate in preserving its temporal features. Here we examined the contribution of the persistent and resurgent components of voltage-gated Na+ currents in modulating the burst discharge in sensory neurons.

Cell adherence and drug delivery from particle based mesoporous silica films.

Spatially and temporally controlled drug delivery is important for implant and tissue engineering applications, as the efficacy and bioavailability of the drug can be enhanced, and can also allow for drugging stem cells at different stages of development. Long-term drug delivery over weeks to months is however difficult to achieve, and coating of 3D surfaces or creating patterned surfaces is a challenge using coating techniques like spin- and dip-coating. In this study, mesoporous films consisting of SBA-15 particles grown onto silicon wafers using wet processing were evaluated as a scaffold for drug delivery.

Room Temperature Uniaxial Magnetic Anisotropy Induced By Fe-Islands in the InSe Semiconductor Van Der Waals Crystal.

The controlled manipulation of the spin and charge of electrons in a semiconductor has the potential to create new routes to digital electronics beyond Moore's law, spintronics, and quantum detection and imaging for sensing applications. These technologies require a shift from traditional semiconducting and magnetic nanostructured materials. Here, a new material system is reported, which comprises the InSe semiconductor van der Waals crystal that embeds ferromagnetic Fe-islands.

Synthesis and Characterization of Novel Fluoro-glycosylated Porphyrins that can be Utilized as Theranostic Agents.

Small molecules with modalities for a variety of imaging techniques as well as therapeutic activity are essential, as such molecules render opportunities to simultaneously conduct diagnosis and targeted therapy, so called theranostics. In this regard, glycoporphyrins have proven useful as theranostic agents towards cancer, as well as noncancerous conditions. Herein, the synthesis and characterization of heterobifunctional glycoconjugated porphyrins with two different sugar moieties, a common monosaccharide at three sites, and a 2-fluoro-2-deoxy glucose (FDG) moiety at the fourth site are presented.

Synthesis and Characterization of Novel Fluoro-glycosylated Porphyrins that can be Utilized as Theranostic Agents.

Invited for this month's cover picture is the group of Professor Peter Nilsson at the Department of Physics, Chemistry and Biology at Linköping University (Sweden). The cover picture shows a fluoro-glycoporphyrin that selectively targets cancer cells. The selectivity towards cancer cells are afforded due to proper functionalization of the porphyrin scaffold with specific carbohydrates, and the cancer cells can be visualized because of the intrinsic fluorescence from the porphyrin.

Genomic Regions Associated With Interspecies Communication in Dogs Contain Genes Related to Human Social Disorders.

Unlike their wolf ancestors, dogs have unique social skills for communicating and cooperating with humans. Previously, significant heritabilities for human-directed social behaviors have been found in laboratory beagles. Here, a Genome-Wide Association Study identified two genomic regions associated with dog's human-directed social behaviors.

Device Performance of APFO-3/PCBM Solar Cells with Controlled Morphology.

Polymer/fullerene solar cells with three different device structures: A) diffuse bilayer, B) spontaneously formed multilayer, and C) vertically homogenous thin films, are fabricated. The photocurrent/voltage performance is compared and it is found that the self-stratified structure (B) yields the highest energy conversion efficiency.

Active control of epithelial cell-density gradients grown along the channel of an organic electrochemical transistor.

Complex patterning of the extracellular matrix, cells, and tissues under in situ electronic control is the aim of the technique presented here. The distribution of epithelial cells along the channel of an organic electrochemical transistor is shown to be actively controlled by the gate and drain voltages, as electrochemical gradients are formed along the transistor channel when the device is biased..

Whose body is it anyway? Verbalization, embodiment, and the creation of narratives.

This article examines the creation of narratives between people with severe disabilities and the personnel working with them. It shows that although a co-created narrative of what it means to be severely disabled (the story of dependence) seems to prevail, another narrative (the story of autonomy) is also told, where the story of dependence is rejected by the person with disabilities. However, this story of autonomy only becomes clear if we recognize three central claims: (1) there is a connection between where the physical body of the person with disabilities is positioned in space and what he or she is allowed or able to be and do; (2) since the body is a communicative tool, the moving of the body could be interpreted as a narrative, told through the embodiment of space; and (3) the embodied story can challenge existing social structures.
