Achieving superior therapeutic effects on methicillin‐resistant Staphylococcus aureus infection via simple sulfonation process for preparing zwitterionic photosensitizer

open access: yesInterdisciplinary Medicine, EarlyView.
The sulfonated zwitterionic photosensitizer (PYSO3) is synthesized by reacting maleic anhydride derivatives with 4‐aminopyridine to form PY, followed by sulfonation with 1,4‐butane sultone. It exhibits both photothermal and photodynamic properties, enabling effective eradication of MRSA and biofilms, as well as promoting wound healing in mice ...

Overview of Diagnostic Ultrasound Safety

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,

Biogenic Synthesis of Silver and Iron Nanoparticles Derived From Grewia Optiva Leaf Extract: A Novel Approach for Antidiabetic, Anticoagulant and Anti‐Inflammatory Therapies

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT This study presents the green synthesis of silver (Ag‐NPs) and iron nanoparticles (Fe‐NPs) using aqueous leaf extract of Grewia optiva as a natural reducing and stabilizing agent. The extract was prepared using a Kjeldahl apparatus under controlled heating. Nanoparticle synthesis was optimized by varying pH, temperature, and salt concentration,
