A cobalt σ-alkane complex, [Co(Cy P(CH ) PCy )(norbornane)][BAr ], was synthesized by a single-crystal to single-crystal solid/gas hydrogenation from a norbornadiene precursor, and its structure was determined by X-ray crystallography. Magnetic data show this complex to be a triplet. Periodic DFT and electronic structure analyses revealed weak C-H→Co σ-interactions, augmented by dispersive stabilization between the alkane ligand and the anion microenvironment. The calculations are most consistent with a η :η -alkane binding mode.

Objectives: The complex life experience of speaking two or more languages has been suggested to preserve cognition in older adulthood. This study aimed to investigate this further by examining the relationship between multilingual experience variables and cognitive functioning in a large cohort of older adults in the diversely multilingual north of the Netherlands.
Method: 11,332 older individuals participating in the Lifelines Cohort Study completed a language experience questionnaire.

Objective: Segmentation of individual thigh muscles in MRI images is essential for monitoring neuromuscular diseases and quantifying relevant biomarkers such as fat fraction (FF). Deep learning approaches such as U-Net have demonstrated effectiveness in this field. However, the impact of reducing neural network complexity remains unexplored in the FF quantification in individual muscles.

Background: Predicting response to targeted cancer therapies increasingly relies on both simple and complex genetic biomarkers. Comprehensive genomic profiling using high-throughput assays must be evaluated for reproducibility and accuracy compared with existing methods.
Methods: This study is a multicenter evaluation of the Oncomine™ Comprehensive Assay Plus (OCA Plus) Pan-Cancer Research Panel for comprehensive genomic profiling of solid tumors.
Beyond the Herald Patch: Exploring the Complex Landscape of Pityriasis Rosea.

Pityriasis rosea (PR) is a prevalent dermatological condition characterized by a distinctive herald patch, followed by secondary eruptions, often forming a "Christmas tree" pattern on the trunk. Despite its recognizable clinical presentation, the etiology of PR remains uncertain, with hypotheses pointing to both infectious and noninfectious origins. Human herpesviruses (HHV) 6 and 7 have been implicated, with evidence suggesting viral reactivation as a potential trigger.
