G3 (Bethesda)

January 2025

Department of Biological Sciences, University of North Carolina at Charlotte, 9201 University City Blvd, Charlotte, North Carolina 28223.

Cnidarians (sea anemones, corals, hydroids, and jellyfish) are a key outgroup for comparisons with bilaterial animals to trace the evolution of genomic complexity and diversity within the animal kingdom, as they separated from most other animals 100s of millions of years ago. Cnidarians have extensive diversity, yet the paucity of genomic resources limits our ability to compare genomic variation between cnidarian clades and species. Here we report the genome for Edwardsia elegans, a sea anemone in the most specious genus of the family Edwardsiidae, a phylogenetically important family of sea anemones that contains the model anemone Nematostella vectensis.

Plantar sensation associates with gait instability in older adults.

J Neuroeng Rehabil

January 2025

Department of Mechanical & Aerospace Engineering, University of Florida, Gainesville, FL, USA.

Background: Advanced age brings a loss of plantar sensation, represented, for example, as higher sensation thresholds in standardized testing. This is thought to contribute to an increased risk of falls among older adults - an intuitive premise that has yet to be fully investigated, especially in the context of walking balance. The purpose of this study was to quantify the association between plantar sensation and the instability elicited by a suite of walking balance perturbations that differ in direction and context in a cohort of n = 28 older adults (73.

Using Classifiers To Predict Catalyst Design for Polyketone Microstructure.

J Am Chem Soc

January 2025

Department of Chemistry and Biochemistry, University of California, Los Angeles, Los Angeles, California 90095, United States.

We applied a classifier method to predict palladium catalysts for the formation of nonalternating polyketones via the copolymerization of CO and ethylene; current examples are limited to using phosphine sulfonate and diphosphazane monoxide supporting ligands. With the reported workflow, we discovered two new classes of palladium complexes capable of achieving the synthesis of nonalternating polyketones with a lower CO content than those made by known palladium catalysts. Our results show that we doubled the number of classes of palladium compounds that can catalyze the formation of this type of polymer.

Cellular senescence is a phenotypic state that contributes to the progression of age-related disease through secretion of pro-inflammatory factors known as the senescence-associated secretory phenotype (SASP). Understanding the process by which healthy cells become senescent and develop SASP factors is critical for improving the identification of senescent cells and, ultimately, understanding tissue dysfunction. Here, we reveal how the duration of cellular stress modulates the SASP in distinct subpopulations of senescent cells.

Background: Chordoma is a slow-growing, primary malignant bone tumor that arises from notochordal tissue in the midline of the axial skeleton. Surgical excision with negative margins is the mainstay of treatment, but high local recurrence rates are reported even with negative margins. High-dose radiation therapy (RT), such as with proton or carbon ions, has been used as an alternative to surgery, but late local failure remains a problem.

Association of Prehabilitation in the Precystectomy Pathway in Patients With Bladder Cancer on Postoperative Outcomes.

Clin Genitourin Cancer

December 2024

University of North Carolina School of Medicine, Chapel Hill, NC; University of North Carolina Lineberger Comprehensive Cancer Center, Chapel Hill, NC; Department of Urology, University of North Carolina, Chapel Hill, NC.

Purpose: Prehabilitation in patients with bladder cancer recommended for cystectomy has the potential to improve functional status and outcomes after cystectomy. Prior research has shown that increasing exercise preoperatively can improve strength and quality of life, but research has not yet investigated the impact on length of stay, readmissions, complications and mortality.

Methods: We compared historical controls (2021-2022) for patients with bladder cancer who underwent radical cystectomy at a major academic center to those referred for prehabilitation consultation (2023) on postoperative outcomes, namely hospital length of stay, 30 and 90 day readmission rates, postoperative complications and 90-day mortality.

Oppenauer-type oxidations are catalyzed by air- and moisture-stable, sustainable, (cyclopentadienone)iron carbonyl compounds, but the substrate scope is limited due to the low reduction potential of acetone, which is the most commonly used hydrogen acceptor. We discovered that furfural, an aldehyde derived from cellulosic biomass, is an effective hydrogen acceptor with this class of catalysts. In general, reactions using furfural as the hydrogen acceptor led to higher isolated yields of ketones and aldehydes compared to those using acetone.

Monte Carlo molecular simulations of curve-shaped rods show the propensity of such shapes to polymorphism revealing both smectic and polar nematic phases. The nematic exhibits a nanoscale modulated local structure characterized by a unique, polar, -symmetry axis that tightly spirals generating a mirror-symmetry-breaking organization of the achiral rods-form chirality. A comprehensive characterization of the polarity and its symmetries in the nematic phase confirms that the nanoscale modulation is distinct from the elastic deformations of a uniaxial nematic director in the twist-bend nematic phase.
