Background: High-functional cosmetic products combined with the concept of "treatment" cosmetics are being introduced to the market. Cosmetic products containing a skin-derived microbiome, a three-dimensional (3D) stem cell culture medium, and low-molecular-weight collagen are being introduced, and these products are leading the cosmeceutical market. We aimed to confirm the potential of a 3D stem cell culture medium-containing cream as a skin-whitening and moisturizing product.
Aim: To determine the enhancing effects of a cream containing 3D adipose tissue-derived mesenchymal stem cell-conditioned media (3D ADMSC-CM) on whitening and moisturization.
Methods: The inhibitory activities of tyrosinase (TYR) and melanin were confirmed using 3D ADMSC-CM. Furthermore, hyaluronic acid expression in 3D ADMSC-CM was verified. The clinical efficacy of the cream containing 3D ADMSC-CM was established by evaluating its antioxidant properties and effects on skin tone, radiance, freckles, and moisturization.
Results: The use of 3D ADMSC-CM suppressed the inhibitory effects of TYR and melanin by approximately 24% and 33%, respectively, and increased the expression of hyaluronic acid synthase. A significant difference was observed after 4 weeks of using 3D ADMSC-CM in the skin antioxidant evaluation. After 2 and 4 weeks of use, skin tone and radiance increased and skin freckles decreased significantly. Under extremely cold and dry weather conditions, the use of the cream increased skin moisturization.
Conclusions: The 3D ADMSC-CM cream evaluated in an environment similar to the human body was found to enhance skin whitening and moisturization and can therefore be used in the skin care and cosmetic industries as a biocosmetic product.

The effects of dairy sterilization techniques (65 °C/30 min, 72 °C/15 s, 85 °C/15 s, 100 °C/5 min, and 121 °C/5 s) on the epigallocatechin-3-gallate-casein (EGCG-CS) complexes were investigated through the structural and functional characteristics in this work. Fourier transform infrared spectroscopy (FT-IR) detection showed the redshirting of the absorption peak suggested structural changes in the amide I area. Field emission scanning electron microscopy (FESEM) and viscosity measurements proved that treatments above 85 °C broke non-covalent bonds, leading to instability and low viscosity of EGCG-CS.

Gelatin, a natural and edible polymer, has attracted wide attention for use in food and edible packaging applications. However, its inadequate properties, especially poor flexibility, limit its broader utilization. Hybridizing different polymers is a promising strategy to achieve enhanced properties.

In this study, ultrasound-assisted glycated ovalbumin (G-UOVA) based on natural deep eutectic solvents (NADES) was prepared using response surface optimization. The binding affinity of (-)-gallocatechin gallate (GCG) to native OVA (NOVA), ultrasound treated OVA (UOVA), glycated OVA (GOVA), and G-UOVA followed G-UOVA > GOVA > UOVA > NOVA. The effects of various modifications and GCG binding on the secondary structure, particle size, and thermal stability of NOVA were investigated.

A novel biomimetic molecular imprinted polymer chip with fluorescence (FL) and structural (STR) states, inspired by color patterns of chameleon skin, is fabricated for detecting diethylstilbestrol (DES). The chip features a regularly structured, non-closed-packed (NCP) colloidal photonic crystal (CPC) lattice made monodisperse MIP spheres containing fluorescence poly ionic liquid (FPIL) pigments. The FL color originates from FPIL pigments and is further enhanced by the Purcell effect, while the STR color results from the periodic arrangement of the NCP CPC structure.

To investigate the effect of High-Frequency Electric Welding (HFEW) on intestinal tissue healing, we performed end-to-end anastomosis experiments in New Zealand rabbits. Within one week post-surgery, animals exhibited normal vital signs, replaced necrotic tissue with healthy collagen, and showed improved tissue strength while inflammation decreased. By day 60, tissue pathology and function fully recovered, resembling normal tissue.
