Influence of chitosan-capped quercetin nanoparticles on chitosan/poly(vinyl) alcohol multifunctional films: A sustainable approach for bread preservation.

Food packaging industries are growing to meet consumer demand and prevent pollution by adopting significant biopolymer advancements. Therefore, this study aimed to develop functionally active chitosan (CS)/polyvinyl alcohol (PVA)-based biopolymer films and evaluate the effect of Justicia Adhatoda extract (JAE), pure quercetin (Q), and CS-capped quercetin nanoparticles ((Q) NPs) on sustainable bread packaging. CS was successfully loaded onto (Q) by the one-pot method, which was confirmed by light absorption spectroscopy (UV), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD).

Analysis of the biomolecular profile by Fourier transform vibrational spectroscopy (FT-IR) in Acinetobacter baumannii after application of photodynamic therapy with curcumin "in vitro ".

Acinetobacter baumannii stands out for its antimicrobial resistance and high capacity to cause hospital infections, posing a severe threat to global public health. Thus, there is an urgent need for new therapeutic strategies. This work applied photodynamic therapy (PDT) with curcumin to Acinetobacter baumannii, and bacterial cell viability was assessed.

Silk-Corn Zein Alloy Materials: Influence of Silk Types (Mori, Thai, Muga, Tussah, and Eri) on the Structure, Properties, and Functionality of Insect-Plant Protein Blends.

Biocompatible materials fabricated from natural protein polymers are an attractive alternative to conventional petroleum-based plastics. They offer a green, sustainable fabrication method while also opening new applications in biomedical sciences. Available from several sources in the wild and on domestic farms, silk is a widely used biopolymer and one of the strongest natural materials.

Lower Cranial Nerves in the Neck: An Anatomical Study.

Objectives The aim of this anatomical study was to analyze distances and anatomical relations between the lower cranial nerves and important neck landmarks. Methods Anatomical study based on neck dissection in Thiel-embalmed cadavers. Anatomical relations and distances between the vagus (X), accessory (XI), and hypoglossal (XII) nerves and important neck landmarks were registered and compared.
