Beyond predation: Fish-coral interactions can tip the scales of coral disease.

Coral reefs are critical ecosystems, fostering biodiversity and sustaining the livelihoods of millions globally. Nonetheless, they confront escalating threats, with infectious diseases emerging as primary catalysts for extensive damage, surpassing the impacts of other human-induced stressors. Disease transmission via biotic factors, particularly during fish predation, is a crucial yet often overlooked pathway.

Cationic conjugated polymers with tunable hydrophobicity for efficient treatment of multidrug-resistant wound biofilm infections.

Biofilm-associated infections arising from antibiotic-resistant bacteria pose a critical challenge to global health. We report the generation of a library of cationic conjugated poly(phenylene ethynylene) (PPE) polymers featuring trimethylammonium terminated sidechains with tunable hydrophobicity. Screening of the library identified an amphiphilic polymer with a C hydrophobic spacer as the polymer with the highest antimicrobial efficacy against biofilms in the dark with excellent selectivity.

Peripheral Ameloblastoma Resembling an Exophytic Gingival Lesion: A Report of a Rare Case.

Peripheral ameloblastoma is a rare, benign, slow-growing odontogenic neoplasm prevalent in the mandible. It originates from the odontogenic epithelium and its remnants, and its histological characteristics are identical to those of intraosseous ameloblastoma. It is less aggressive and invasive than its intraosseous variety, with a low recurrence rate.

Neo-aortic valve replacement in arterial switch operation in a 9-year-old child.

The surgical management of d-transposition of the great arteries (dTGA), ventricular septal defect (VSD), and left ventricular outflow tract obstruction (LVOTO) poses intricate challenges, demanding tailored surgical interventions. This case report elucidates a patient involving a 9-year-old child with dTGA, VSD, and LVOTO with a dysplastic pulmonary valve with adequate annulus who underwent neo-aortic valve replacement with a mechanical prosthesis, arterial switch, and VSD closure. The recovery of the patient was uneventful and follow-up echocardiogram and clinical evaluation at 18 months have remained satisfactory.

Rapid Identification of Cell Types and Phenotypic States Using a One-Polymer Multichannel Nanosensor Fabricated via Flash Nanoprecipitation.

Cell state transitions are fundamental in biology, determining how cells respond to environmental stimuli and adapt to diseases and treatments. Cell surface-based sensing of geno/phenotypes is a versatile approach for distinguishing different cell types and states. Array-based biosensors can provide a highly sensitive platform for distinguishing cells based on the differential interactions of each sensing element with cell surface components.
