Summary: In this study, light-colored lignin was efficiently extracted from bamboo shoot shells using a hydrated deep eutectic solvent (DES) pretreatment. The hydrated DES protected the β-O-4 linkage and maintained the light color of lignin. The extracted lignin exhibited superior antioxidant performance and tyrosinase inhibitory capacity, leading to a remarkable enhancement of the SPF value when incorporated into a commercial suncream.

Summary: Overexposure to solar radiation has become a growing concern due to the damage it causes to the skin. Previous studies have shown that an extract from the Colombian high-mountain plant Baccharis antioquensis, enriched with glycosylated flavonoids, has potential as a photoprotector and antioxidant. This study aimed to develop a dermocosmetic formulation with broad-spectrum photoprotection using hydrolysates and purified polyphenols from this plant. The extraction, hydrolysis, purification, and characterization of the main compounds were evaluated, as well as the photoprotective capacity and safety of the formulation.

Summary: The survey found that the majority of Italian dermatologists have positive views on oral photoprotection in preventing skin cancer, especially acknowledging the effectiveness of nicotinamide. Most dermatologists had prescribed oral photoprotectors, with nicotinamide being the most commonly prescribed, usually in combination with topical photoprotectors. The vast majority of dermatologists were aware of scientific publications demonstrating the impact of systemic photoprotectors on nonmelanoma skin cancers.

Summary: Various substances, including collagen and ascorbic acid, have been studied for their inhibitory effects on skin aging. The synergistic effect of collagen and ascorbic acid was achieved in a product called TEENIALL. In vitro and clinical trials confirmed the effectiveness of this product in improving wrinkles, lifting skin, and reducing pigmentation.

Summary: By incorporating amyloid-like protein aggregates into sunscreen, the study successfully improves the interfacial stability of the sunscreen on the skin, preventing leakage and entry of synthetic ingredients into aquatic environments. The modified sunscreen shows high retention ratio in aquatic environments, indicating the potential for developing leakage-free sunscreens with low ecological hazards and long-lasting UV protection.

Summary: This study presents a multicolor chemiluminescence sensing strategy for the discrimination of five antioxidants. By fabricating multilayer paper chips and utilizing chemiluminescence reactions, unique R, G, and B values were generated in the chemiluminescence images for antioxidant discrimination. The experimental results demonstrate the accuracy and feasibility of this strategy in identifying antioxidants.

Summary: Studies have shown that incorporating OMC into liquid crystal systems can improve its delivery to the skin and reduce its systemic absorption, thereby avoiding harmful effects. The surfactant-based systems developed in this study have great potential for delivering OMC to the skin effectively.

Summary: Three out of five beachgoers in the northern coast of Peru had one or more sunburns last summer. Factors associated with a higher sunburn frequency include prolonged sun exposure at the beach and irregular use of a hat or cap. Skin Phototypes III-IV were associated with a lower frequency of sunburns.

Summary: This study reveals that OPN3 is an important photoreceptor in human epidermal keratinocytes, and it is critical for the formation of supranuclear cap mediated by UVA. OPN3 mediates the formation of supranuclear cap through the calcium-dependent G protein-coupled receptor signaling pathway, which ultimately upregulates the expression of Dync1i1 and DCTN1 in human epidermal keratinocytes by activating calcium/CaMKII, CREB, and Akt signal transduction. These findings greatly expand our understanding of the phototransduction mechanisms involved in physiological function in skin keratinocytes.

Summary: The presence of desmoplasia in pancreatic ductal adenocarcinoma (PDAC) is associated with poor treatment outcomes and reduced drug delivery. By analyzing collagen subtypes in PDAC tumors following different treatment regimens, immunofluorescence profiling can predict long-term survival and tumor growth inhibition. This information can aid in personalized treatment and improve patient survival.

Summary: Thin film coatings with potent antibacterial properties are widely used in medical devices, frequently touched surfaces, and food packaging. However, achieving antibacterial performance under both light and dark conditions remains a challenge. In this study, we successfully prepared AgBr-coated ZnO nanorod thin film architecture using a unique surfactant-mediated solution-phase spin-coating approach. The resulting structures showed dual functionality as antimicrobial agents and photosensitizers, effectively enhancing the visible-light photodisinfection efficacy of ZnO nanorods. The concentration of the surfactant-based precursor solution could be modulated to control the AgBr content. Additionally, components like urea and lactic acid were found to enhance the photocatalytic efficiency of the structures.
