In vitro activity and comparative efficacy of novel nitrofuran-containing ciprofloxacin analogs against bacterial pathogens including ciprofloxacin-resistant Staphylococcus aureus

Abstract The rapid rise of antimicrobial resistance, especially in Staphylococcus aureus , highlights the urgent need for improved antibacterial agents. In 2019 alone, AMR caused an estimated 1.27 million deaths and contributed to nearly 5 million more globally. Here, we present...

Disentangling the species diversity of Inocybe sect. Petiginosae (Inocybaceae) in Europe and North America

Abstract A multigene phylogenetic assessment of European and North American species in Inocybe sect. Petiginosae based on ITS, LSU and RPB2 rDNA sequence data was undertaken to enable a systematic revision. Specimens collected in northern boreal to arctic-alpine ecosystems were s...

The Compliance Trap and Relational Anchors in Structured Instructional Leadership

Instructional leadership is often displaced by compliance requirements, operational demands, and formal evaluation. This qualitative secondary analysis examined how teachers and principals described organizational pressures and relational practices during a 14-day Build Rapport,...

Developing a Workplace Institutional Betrayal Measure Using a Survivor-Led Qualitative Methodology

Institutional betrayal, a concept coined by Jennifer Freyd, has been used to understand institutional responses to sexual violence predominantly in a university setting and specific workplaces (e.g., military). The Institutional Betrayal Questionnaire (IBQ) has been essential in...

Measuring Fluid Flow and Tracking Bio-Mediated Precipitation in Propped Shale Fractures

Abstract Hydraulic fracturing has enabled the extraction of oil and gas from ultra-low permeability shale formations by creating propped fractures that serve as primary fluid flow conduits. While numerical models have advanced understanding of fluid flow through these fractures,...

PS4-10. Effects of Different Dietary Dried Corn Distillers Grains Plus Solubles Inclusion Levels on Postprandial Glycemic and Insulinemic Responses in Horses.

Abstract Evaluation of postprandial glycemic and insulinemic responses is fundamental to assess the metabolic effects of alternative feed ingredients in equine nutrition. Dried corn distillers grains plus solubles (DDGS), a by-product with distinct fermentative and energetic char...

164. Developmental Plasticity: Maternal Nutrition's Impacts Through the Lifecycle of Livestock.

Abstract Developmental programming is an area of interest for researchers across species and animal science disciplines. Work examining various nutrient restrictions, supplementation protocols, and timing of dietary manipulations have all improved our understanding of the connect...

PS13-11. Effect of Forb Inclusion on Digestion and Metabolism of Warm-Season Forage Diets in Beef Cattle.

Abstract Warm-season forbs have gained attention in grazing systems for their high productivity, favorable nutritive value, and potential to reduce enteric methane (CH4) emissions in beef cattle. However, variable palatability and limited voluntary intake often prevent achieving...

Nurturing primary students’ identity-enhancing practices through mathematical modeling routines

Abstract Calls for mathematics teaching and learning that fosters critical thinking and problem solving, and cultivates competencies such as collaboration and empathy, require curricular interventions that support students in developing strong mathematics identities. We argue tha...

Bacteriophages in Antarctic Subglacial Lakes Reveal Novel Biodiversity and Biogeochemical Potential

Abstract Of the more than 600 subglacial lakes identified in Antarctica thus far, Whillans Subglacial Lake (SLW) and Mercer Subglacial Lake (SLM) are the only lakes to have been directly and cleanly sampled. Although hydrologically isolated from direct marine contact for approxim...

Strategic fisheries closure balances harvest opportunity and stock diversity in a large Alaska river basin

Effective conservation of exploited species requires balancing harvest opportunities with the protection of biodiversity. In Pacific salmon, biodiversity among populations contributes to basin-wide resilience, yet spatiotemporal dynamics of adult migrating Chinook salmon remain p...

Protein Thioether Crosslinks Installed by a SPASM-Containing Radical SAM Enzyme from Methanogenic Archaea

Abstract Cysteine is a vital amino acid with wide biological utility, serving functions in catalysis, ligand binding, and maintenance of protein structures. In a subset of natural products, termed ribosomally synthesized and post-translationally modified peptides (RiPPs), multipl...

The scaling of motion: dynamic body acceleration declines with body mass in black-tailed prairie dogs

Dynamic body acceleration (DBA) derived from animal-borne accelerometers is widely used to infer behaviour and movement-related energetic expenditure, yet its interpretation in comparative contexts may be complicated by body size. Biomechanical scaling predicts that smaller anima...

The plausible relationship between deep long-period earthquakes and volatiles: a case study of the Alaska-Aleutian arc

Abstract Deep long-period (DLP) earthquakes are observed beneath volcanoes in various tectonic settings during background activity, unrest, and eruption. The exact processes generating DLPs have been subject to ongoing debate, as they may provide insight into deep magmatic plumbi...

Calculation of Field-line Slippage Rates in Coronal Simulations

Abstract We present the universal Slippage calculator ( USlip ), an extension of the universal Fieldline Tracer ( UFiT ), which computes magnetic field line slippage rates from an input magnetic field defined on a structured grid. The slippage rate provides a local, physically gr...

Anterior Cruciate Ligament Injury: Beyond the Ligament- A Neurophysiological Perspective

The anterior cruciate ligament (ACL) is not merely a passive stabilizer of the knee, yet its injuries are still commonly treated as a mechanical problem despite growing evidence implicating the central nervous system (CNS). This mini review highlights the ACL as a critical sensor...

Reproducibility, Replicability, and Research Quality in Homogeneous Catalysis

Abstract Researchers from all sectors of homogeneous catalysis convened in response to concerns regarding reproducibility in science to analyze the issue and provide recommendations. In addition to an in-person workshop, the group engaged the broader homogeneous catalysis communi...

Targeted Analysis of Chondrocyte Central Metabolites in Response to Cyclical Compression and Shear Deformations

Osteoarthritis results in deterioration of articular cartilage, the soft tissue covering articulating surfaces of bones in joints like the knee and hip. Cyclical mechanical stimulation of articular cartilage results in synthesis of cartilage matrix, suggesting that therapeutic me...

Building Capacity at Home: Tribal College Faculty Pursuing Graduate Degrees Through a Reciprocal University Partnership

ABSTRACT Thirteen Tribal College (TCU) faculty in Montana are pursuing graduate degrees through a reciprocal partnership with Montana State University (MSU) to strengthen TCU capacity and expand local educational opportunities. All TCUs in Montana serve as community colleges for...

Genomic catalogue of giant viruses reveals expanded diversity and functional potential

Nucleocytoplasmic large DNA and Mirusviricota viruses exhibit taxonomic richness which continually expands due to metagenomic sequencing. Here we curate a database of giant virus metagenome-assembled genomes (GVMAGs V2), comprising 8,508 species-level representatives from 18,727...
