Latent classes of acute grief reactions in the shadow of collective trauma and its predictors in bereaved adults.

The current study explored grief reaction profiles after the October 7th, 2023, Israeli massacre regarding the loss of significant others. It investigated factors worsening pre-existing grief in 2,028 adult civilians, with 1,263 reporting pre- or post-massacre loss. Participants completed self-reports on prolonged grief disorder (PGD), post-traumatic stress disorder (PTSD), complex PTSD (CPTSD), cognitive emotional regulation (CER), and assumptive worldviews.

Intracellular polarization of RNAs and proteins in the human small intestinal epithelium.

The intestinal epithelium is a polarized monolayer of cells, with an apical side facing the lumen and a basal side facing the blood stream. In mice, both proteins and mRNAs have been shown to exhibit global basal-apical polarization; however, polarization in the human intestine has not been systematically explored. Here, we employed laser-capture microdissection to isolate apical and basal epithelial segments from intestinal tissues of 8 individuals and performed RNA sequencing and mass-spectrometry proteomics.

Efficient method for simulating ionic fluids between polarizable metal electrodes.

We introduce an efficient method for simulating Coulomb systems confined by conducting planar surfaces. The new approach is suitable for both coarse-grained models and all-atom simulations of ionic liquids between polarizable metal electrodes. To demonstrate its efficiency, we use the new method to study the differential capacitance of an ionic liquid.

Can the subjective perception of trauma effectively differentiate between International Classification of Diseases-11 PTSD and complex PTSD? The 2022 Russian invasion analysis.

Objective: This study is aimed to test the association of the Subjective Traumatic Outlook (STO) concept for distinguishing between posttraumatic stress disorder (PTSD) and complex PTSD. Focusing on identity dimensions within identity theory, the research aims to understand how subjective factors influence psychological outcomes, especially in the context of trauma during prolonged war. Findings can inform our understanding of the perception of trauma during wartime.

Hypoxia-dependent recruitment of error-prone DNA polymerases to genome replication.

Hypoxia is common in tumors and is associated with cancer progression and drug resistance, driven, at least in part, by genetic instability. Little is known on how hypoxia affects Translesion DNA Synthesis (TLS), in which error-prone DNA polymerases bypass lesions, thereby maintaining DNA continuity at the price of increased mutations. Here we show that under acute hypoxia, PCNA monoubiquitination, a key step in TLS, and expression of error-prone DNA polymerases increased under regulation of the HIF1α transcription factor.
