Article Abstract
The current study is focused on the biosynthesis of nutmeg oil/ polyurethane/ZnONPs bionanocomposite film for immunomodulatory and antioxidant activities. The fabricated film was prepared by using naturally extracted nutmeg oil functionalized with ZnONPs in the presence of polyutherane (PU) medium. The bionanocomposite film was obtained by incorporating dropwise 10 % (/) of nutmeg oil to the PU solution/ZnONPs blend. The active constituents of nutmeg oil were determined by gas chromatography coupled with mass spectrometry (GC-MS). The morphological characteristics of the resulting bionanocomposite film were confirmed using various microscopic and spectroscopic methods. Immunomodulatory potential of bionanocomposite was evaluated for RAW 264.7 macrophages. The results exhibited an excellent reduction in inflammatory cytokines (IL-6, IL-10, and TNFα) secretions after the treatment with bionanocomposite. The bionanocomposite exerted the highest inhibitory effects on certain cell signaling constituents that influence the initiation of expression of proinflammatory cytokines. The bionanocomposite was also tested for DPPH and ABTS free radicals scavenging assays and showed excellent antioxidant potential with IC values (0.28 ± 0.22 and 0.49 ± 0.36), respectively. The outcomes suggested promising immunomodulatory and antioxidant potentials for the biogenic synthesized nutmeg oil/PU/ZnONPs polymeric bionanocomposite.

Bone defect therapy frequently encounters bacterial infections and chronic inflammation, which impair bone regeneration and threaten implant stability. Iron oxide nanoparticles have attracted attention due to cost-effectiveness, biocompatibility, and metabolic safety. However, iron oxide nanoparticles still struggle to balance low-temperature efficient antibacterial activity, effective immunomodulation, and bone regeneration.

Metal ions play a vital role in the health of the modern human body, but deficiencies in mineral elements have created health risks worldwide. However, mineral supplements currently available on the market are very limited due to poor solubility, low bioavailability, and the possibility of adverse effects on the gastrointestinal tract. In contrast, protein-derived metal-chelating peptides have received a lot of attention because of their stability, safety, and very high bioavailability.

Gastrointestinal eubiosis is essential for maintaining overall host wellbeing. Post-weaning diarrhea (PWD) is a common issue in pig development, arising from weaning stress, which disrupts the gut microbiota balance and increases susceptibility to infections. The primary bacterial pathogen linked to PWD is enterotoxigenic (ETEC).

Acute lung injury (ALI) is characterized by the excessive accumulation of reactive oxygen species (ROS), which triggers a severe inflammatory cascade and the destruction of the alveolar-capillary barrier, leading to respiratory failure and life-threatening outcomes. Considering the limitations and adverse effects associated with current therapeutic interventions, developing effective and safe strategies that target the complex pathophysiological mechanisms of ALI is crucial for improving patient outcomes. Herein, we developed an inhalable, multifunctional nanotherapeutic (MSCNVs@CAT) by encapsulating catalase (CAT) in mesenchymal-stem-cell-derived nanovesicles (MSCNVs).
