Previously, we observed curcumin improves aging-associated memory impairment in D-galactose (D-gal) and normal-aged (NA) mice. Evidence showed that multiple agents can be used in managing aging-induced memory dysfunction, drawn by the contribution of several pathways. Curcumin and Epigallocatechin 3 gallate (EGCG) combination substantially reduced the oxidative stress that commonly mediates aging. This study examined the combined effect of EGCG and curcumin on memory improvement in two recognized models, D-gal and normal-aged (NA) mice. The co-administration of EGCG and curcumin significantly (p < 0.05) increased retention time detected by passive avoidance (PA) and freezing response determined in contextual fear conditioning (CFC) compared to the discrete administration of EGCG or curcumin. Biochemical studies revealed that the combination of EGCG and curcumin remarkably ameliorated the levels (p < 0.05) of glutathione, superoxide dismutase, catalase, advanced oxidation protein products, nitric oxide, and lipid peroxidation compared to the monotherapy of EGCG or curcumin in mice hippocampi. The behavioral and biochemical studies revealed that the combination of EGCG and curcumin showed better improvement in rescuing aging-associated memory disorders in mice. EGCG and curcumin combination could serve as a better choice in managing aging-related memory disorders.

Owing to the high invasion depth and easy formation of biofilms, the treatment of subcutaneous fungal infection is intractable and challenging. Herein, we report an injectable and biodegradable hydrogel with bactericidal, quorum sensing inhibition and antioxidant activities for the in situ treatment of subcutaneous fungal infection. The hydrogel (BEPE) was constructed by irradiating mixed bovine serum albumin (BSA), ε-polylysine and epigallocatechin gallate (EGCG)-loaded mesoporous polydopamine (PDA) under near-infrared (NIR) light.

Hemostasis is the initial step in wound healing, yet significant challenges, such as massive bleeding and infection, often arise. In this study, we developed amphiphilic biodegradable polyester-based segmented polyurethane (SPU) microspheres modified with epigallocatechin gallate (EGCG)-Ag nanoparticles and calcium-alginate cross-linking shell, combining blood absorption with the pro-coagulation properties of Ca and the negative charge of EGCG for synergistic hemostatic effects across various stages of the coagulation cascade. The in vitro blood clotting time of the SPU@EAg@CaAlg microsphere (328.

During surgical procedures, skin and soft tissue wounds are often infected by resistant strains of gram-positive bacteria and gram-negative bacteria, resulting in serious obstacles to the healing of these wounds. Commercially available dressings for such wounds are still insufficient to combat resistant infections. Here, we designed vancomycin and epigallocatechin gallate (EGCG) loaded poly(vinyl)-pyrrolidone-gelatine nanofiber's membrane dressing for potential synergistic efficiency against infected post-surgical wounds.

Cancer is a major global concern. Despite considerable advancements in cancer therapy and control, there are still large gaps and requirements for development. In recent years, various naturally occurring anticancer drugs have been derived from natural resources, such as alkaloids, glycosides, terpenes, terpenoids, flavones, and polyphenols.

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by immune dysregulation and excessive cytokine production. This study aimed to explore the potential of Camellia sinensis L. water extract (CSE) as a treatment for AD by the impact of CSE on inflammatory responses in keratinocytes, particularly concerning the production of inflammatory cytokines and the modulation of signaling pathways relevant to AD pathogenesis.
