Summary: Oral disease is a common condition that has negative impacts on general health and quality of life. Designing therapeutic agents for oral diseases is challenging due to unique features of the oral cavity. In this study, the development of mucoadhesive functional hydrogels for oral applications is reported, using bio-inspired phenolic moieties in a pectin polymer. The results show that these mucoadhesive hydrogels have great potential for treating oral diseases, such as dry mouth and oral ulcers, by promoting tissue repair and providing prolonged drug release.

Summary: More than 58 million metric tonnes of oranges were produced in 2021, and the peels, which account for around one-fifth of the fruit weight, are often discarded as waste in the orange juice industry. Orange pomace and peels are being utilized as sustainable raw materials for nutraceutical products due to their rich content of pectin, phenolics, and limonene, which offer various health benefits. This review focuses on the valorization of orange peels and pomace through different green extraction methods, such as supercritical carbon dioxide (ScCO2) extraction, subcritical water extraction (SWE), ultrasound-assisted extraction (UAE), and microwave-assisted extraction (MAE), highlighting their potential applications in the health and wellness sector. The findings of this review, based on English articles from 2004 to 2022, suggest that green extraction methods can effectively extract high quantities and qualities of bioactive compounds from orange peels and pomace, which can be used in health and wellness products.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
