Growth of Private Equity and Hospital Consolidation in Primary Care and Price Implications.

Importance: Consolidation of physician practices by hospitals and private equity (PE) firms has increased rapidly. This trend is of particular importance within primary care. Despite its significance, there is no systematic evidence on the emerging trends in ownership affiliation of primary care physicians (PCPs) and its association with prices paid for physician services.

Novel Leech Antimicrobial Peptides, Hirunipins: Real-Time 3D Monitoring of Antimicrobial and Antibiofilm Mechanisms Using Optical Diffraction Tomography.

Antimicrobial peptides (AMPs) are promising agents for treating antibiotic-resistant bacterial infections. Although discovering novel AMPs is crucial for combating multidrug-resistant bacteria and biofilm-related infections, their clinical potential relies on precise, real-time evaluation of efficacy, toxicity, and mechanisms. Optical diffraction tomography (ODT), a label-free imaging technology, enables real-time visualization of bacterial morphological changes, membrane damage, and biofilm formation over time.

Enhanced Antibacterial, Anti-Inflammatory, and Antibiofilm Activities of Tryptophan-Substituted Peptides Derived from Cecropin A-Melittin Hybrid Peptide BP100.

The emergence of multidrug-resistant pathogens necessitates the development of novel antimicrobial agents. BP100, a short α-helical antimicrobial peptide (AMP) derived from cecropin A and melittin, has shown promise as a potential therapeutic. To enhance its efficacy, we designed and synthesized 16 tryptophan-substituted BP100 analogs based on helical wheel projections.

Larvicidal and enzyme inhibition effects of Phoenix pusilla derived Methyl oleate and malathion on Aedes aegypti strains.

This study explores the larvicidal potential of methanolic flower extracts from Phoenix pusilla (Pp-Fe), its major compound, and malathion (MLT), against laboratory strain (LS) and field strain (FS) of Aedes aegypti, the dengue mosquito vector. We identified thirty-one derivatives, with methyl oleate (MO) comprising 28.5% of Pp-Fe.
