Cytology to More Clearly Distinguish Solitary Plasmacytoma at the Skull Base.

Solitary plasmacytomas are localized single tumors of monoclonal plasma cells that occur in two variants: solitary plasmacytoma of bone and extraosseous plasmacytoma. Solitary plasmacytoma of bone accounts for only 1%-2% of plasma cell lesions, and extraosseous plasmacytoma is also approximately 1%. These are both very uncommon at the skull base.

Exercise Training in Heart Failure: Current Evidence and Future Directions.

Heart Failure (HF) is a prevalent condition which places a substantial burden on healthcare systems worldwide. Medical management implemented with exercise training (ET) plays a role in prognostic and functional capacity improvement. The aim of this review is to determine the effect of exercise training (ET) on HFpEF and HFrEF patients as well as exercise modality recommendations in frail and sarcopenic subpopulations.

Genomic and mutational analysis of Pseudomonas syringae pv. tagetis EB037 pathogenicity on sunflower.

Background: Pseudomonas syringae pv. tagetis (Pstag) causes apical chlorosis on sunflower and various other plants of the Asteraceae family. Whole genome sequencing of Pstag strain EB037 and transposon-mutant derivatives, no longer capable of causing apical chlorosis, was conducted to improve understanding of the molecular basis of disease caused by this pathogen.

Modeling of magnetic vestibular stimulation experienced during high-field clinical MRI.

Background: High-field magnetic resonance imaging (MRI) is a powerful diagnostic tool but can induce unintended physiological effects, such as nystagmus and dizziness, potentially compromising the comfort and safety of individuals undergoing imaging. These effects likely result from the Lorentz force, which arises from the interaction between the MRI's static magnetic field and electrical currents in the inner ear. Yet, the Lorentz force hypothesis fails to explain observed eye movement patterns in healthy adults fully.

Uveitis and blindness in a closed herd of Equidae following leptospiral infection.

Objective: To describe the ocular findings, chronology of disease, and serum leptospiral titers in a group of horses, mules, and donkeys following an outbreak of leptospirosis.

Methods: Fifty Equidae in central North Carolina had ophthalmic examinations and serum leptospiral microscopic agglutination test (MAT) titers performed every 3-6 months for 24 months followed by a final examination at 34 months.

Results: Throughout the nearly three-year study period, 17 horses (34%; 17/49 horses) developed signs of uveitis; 20 eyes (20/34; 58.
