Low rates of dislocation and reoperation following robotic-assisted total hip arthroplasty for femoral neck fracture.

Introduction: Total hip arthroplasty (THA) is widely used for active, elderly patients with femoral neck fractures (FNF). Compared to THA for osteoarthritis, THA for FNF is associated with a higher incidence of dislocation and reoperation. Robotic assistance may improve component positioning and leg-length restoration in THA, but its use in FNF has not been described.

Structural and Electronic Properties of Poly(ethylene terephthalate) (PET) from Polarizable Molecular Dynamics Simulations.

The environmental and economic challenges posed by the widespread use and disposal of plastics, particularly poly(ethylene terephthalate) (PET), require innovative solutions to mitigate their impact. Such mitigation begins with understanding physical properties of the polymer that could enable new recycling technologies. Although molecular simulations have provided valuable insights into PET interactions with various PET hydrolases, current nonpolarizable force fields neglect the electronic polarization effects inherent to PET interactions.

The Simons Observatory: Design, Optimization, and Performance of Low-Frequency Detectors.

The Simons Observatory (SO) is a cosmic microwave background (CMB) experiment located in the Atacama Desert in Chile that will make precise temperature and polarization measurements over six spectral bands ranging from 27 to 285 GHz. Three small aperture telescopes (SATs) and one large aperture telescope (LAT) will house 60,000 detectors and cover angular scales between one arcminute and tens of degrees. We present the performance of the dichroic, low-frequency (LF) lenslet-coupled sinuous antenna transition-edge sensor (TES) bolometer arrays with bands centered at 27 and 39 GHz.

Ion Mobility-Assisted Free Radical-Initiated Peptide Sequencing.

Free radical-initiated peptide sequencing (FRIPS) is a tandem mass spectrometry technique (MS/MS) that enables radical-based dissociation on instruments only capable of collisional activation. In FRIPS, peptides are chemically-derivatized with a compound that undergoes homolytic cleavage and generates radicals upon collisional activation. These radicals then propagate through the peptide backbone enabling the sequencing of peptide ions.

Design and Characterization of a Gene-Encoding DNA Nanoparticle in a Cell-Free Transcription-Translation System.

DNA nanotechnology has made initial progress toward developing gene-encoded DNA origami nanoparticles (NPs) that display potential utility for future gene therapy applications. However, due to the challenges involved with gene delivery into cells including transport through the membrane, intracellular targeting, and inherent expression of nucleases along with interference from other active proteins, it can be difficult to more directly study the effect of DNA NP design on subsequent gene expression. In this work, we demonstrate an approach for studying the expression of gene-encoding DNA origami NPs without the use of cells.

This Review presents state-of-the-art multiphoton imaging modalities and optical indicators for in vivo brain imaging, highlighting recent advancements and current challenges in the field.

Real-World Use of Tapinarof Cream 1% Once Daily in Patients with Seborrheic Dermatitis: A Case Series.

Seborrheic dermatitis (SD) is an inflammatory skin disease with multifactorial etiology, involving genetic and environmental factors. Many conventional therapies for SD (ie, topical antifungals, topical corticosteroids) are associated with incomplete efficacy, frequent and sometimes rapid disease recurrence, and restrictions on duration of therapy and anatomic sites of application. This may be because they cannot target multiple disease processes and/or are limited by safety considerations.

Quantitative peripheral live single T-cell dynamic polyfunctionality profiling predicts lung cancer checkpoint immunotherapy treatment response and clinical outcomes.

Background: Predictive biomarkers for immune checkpoint inhibitors (ICIs), e.g., programmed death ligand-1 (PD-L1) tumor proportional score (TPS), remain limited in clinical applications.

Frugivore Traits Predict Plant-Frugivore Interactions Using Generalized Joint Attribute Modeling.

Under an adaptive hypothesis, the reciprocal influence between mutualistic plants and frugivores is expected to result in suites of matching frugivore and plant traits that structure fruit consumption. Recent work has suggested fruit traits can represent adaptations to broad groups of functionally similar frugivores, but the role of frugivore traits and within-species variation in structuring fruit consumption is less understood. To address these knowledge gaps, we assess the presence of reciprocal trait matching for the mutualistic ecological network comprising of bats that feed on and disperse seeds.

Characterization of Pediatric Extrathoracic Aerosol Deposition with Air-Jet Dry Powder Inhalers.

The use of air-jet dry powder inhalers (DPIs) offers a number of advantages for the administration of pharmaceutical aerosols, including the ability to achieve highly efficient and potentially targeted aerosol delivery to the lungs of children using the oral or trans-nasal routes of administration. To better plan targeted lung delivery of pharmaceutical aerosols with these inhalers, more information is needed on the extrathoracic (ET) depositional loss in pediatric subjects when using relatively small (e.g.

Paternal activation parenting and growth in children's inhibitory control across early childhood.

Activation parenting (AP) is a parenting construct derived from research and theory on paternal caregiving that includes behaviors that challenge children to approach novel situations, explore their environments, and take physical and socioemotional risks through a balance of encouragement and limit-setting. Although components of AP have been linked to different domains of children's self-regulation skills, comprehensive measures of AP and longitudinal research on families from low socioeconomic backgrounds are lacking. These limitations greatly constrain our understanding of the potential benefits of paternal AP for children's self-regulation development, including the maturation of inhibitory control (IC) in early childhood.

Promotion of Student Success and Positive Chemistry Course Perception through Frequent Metacognitive Reporting.

Explicit metacognitive interventions in undergraduate chemistry courses have been shown to improve student outcomes. Less studied have been the outcomes of students who implicitly and frequently practice metacognition and the resultant effects on the student-instructor relationship. In this project set within a large enrollment introductory chemistry course, we elevated student voice and enhanced student-instructor communication through weekly metacognitive reporting to study the characteristics of reporting students and their perceptions of the effects of metacognitive reporting.

Obinutuzumab Infusion-Related Reactions: Multicenter Retrospective Evaluation of Incidence, Severity, and Risk Factors.

Introduction: Despite standard prevention strategies, obinutuzumab carries a significant risk of infusion-related reactions (IRRs) for patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Reported rates of IRRs vary in phase III clinical trials evaluating obinutuzumab-containing regimens. Although obinutuzumab has a higher rate of severe (grade 3 and higher) IRRs than rituximab, clinical risk factors predicting IRR have not been identified, and therefore strata informing patient-specific risk of IRR have not been applied in practice.
