The growing utilization of Traditional Chinese Medicine (TCM) has resulted in an increase in wastewater. Herein, a new kind of organic-inorganic redox mediator membrane by immobilizing γ-FeO(OH) and aloe-emodin(AE) with the characteristic large π-conjugation anthraquinone structure on PVDF membrane was innovatively achieved. AE exhibiting both electron deficiency and redox activity possesses a co-catalyst role in degradation of tannic acid (TA), aiding in the separation of charge carriers through the sequential hydrogenation and dehydrogenation of AE. The removal rates of TA were 92.8 % in the tannic acid solution and 60.3 % in the simulated rhubarb wastewater by the AE-γ-FeO(OH) membrane under PMS+Vis conditions in 45 min. Also, they show a higher recovery of pure water flux and owning good fouling performance. Overall, this current work presents a novel approach for the design and preparation of organic-inorganic photocatalytic composite membrane using readily available natural products for the purification TCM wastewater.

Purpose: Recurrent cystitis, particularly common in women, substantially diminishes patient quality of life and represents a major clinical practice and public health burden. Increasing development of resistance to antibiotics has encouraged the search for alternative treatments. The benefits of a food supplement associating two strains with proanthocyanidin A-rich cranberry and cinnamon extracts were evaluated in 80 women with a history of cystitis recurrence.

Objectives: Drug-loaded mucoadhesive silk fibroin (SF) microneedle patch can overcome the limitations of low bioavailability and significant pain associated with traditional treatment methods, such as topical application or injection of triamcinolone for oral submucous fibrosis (OSF). However, these systems release the drug too quickly, failing to meet the clinical requirements. This study aims to construct a mucoadhesive SF microneedle patch pre-assembled with silk fibroin nanospheres (SFN) and explore its ability to sustain the release of triamcinolone in the treatment of OSF.

The weak cohesive strength of tissue adhesives hinders their practical applications. To overcome this challenge, we develop a green bio-adhesive that balances both cohesion and adhesion, drawing inspiration from the natural adhesion mechanisms of mussels. This bio-adhesive, referred to as OTS, was ingeniously crafted through the co-assembly of multi-surface-charged chitin nanofibers (OAChN) and tannic acid (TA), integrated with silk fibroin (SF), resulting in a material with enhanced cohesive strength and robust adhesive properties.

A soluble fraction of faba bean protein was conjugated with tannic acid via the free-radical grafting method using a mixture of ascorbic acid and hydrogen peroxide. Surface plasmon resonance showed a strong bonding between them, while the free amino and thiol group measurements indicated tannic acid's bonding with the amino groups and cysteine residues on the proteins. Structural analysis using intrinsic fluorescence and surface hydrophobicity demonstrated tannic acid's interaction with the aromatic and hydrophobic amino acids of the protein.

Cardiovascular diseases (CVD) represent a primary global health challenge. Poor dietary choices and lifestyle factors significantly increase the risk of developing CVD. Legumes, recognized as functional foods, contain various bioactive components such as active peptides, protease inhibitors, saponins, isoflavones, lectins, phytates, and tannins.
