0.5-5% Supramolecular Salicylic Acid Hydrogel is Safe for Long-Term Topical Application and Improves the Expression of Genes Related to Skin Barrier Homeostasis in Mice Models.

Background: As a keratolytic, salicylic acid (SA) can be topically applied in various formulations and doses in dermatology. Supramolecular SA hydrogel, a new SA formulation with higher bioavailability, is developed and commercially available nowadays. However, there still remain concerns that the long-term and continual application of SA at low concentrations may jeopardize the cutaneous barrier properties.

RNA sequencing and metabolic analysis of imiquimod-induced psoriasis-like mice with chronic restrain stress.

Aim: Psoriasis is one of the most common dermatological disorders, characterized by increased epidermal hyperplasia and immune cell infiltration. Psychological stress has been reported to contribute to the severity, aggravation, and relapse of psoriasis. However, the exact mechanism involved in psychological stress's impact on psoriasis is still unclear.

γ-Aminobutyric acid promotes the inhibition of hair growth induced by chronic restraint stress.

Stress plays a critical role in hair loss, although the underlying mechanisms are largely unknown. γ-aminobutyric acid (GABA) has been reported to be associated with stress; however, whether it affects stress-induced hair growth inhibition is unclear. This study aimed to investigate the potential roles and mechanisms of action of GABA in chronic restraint stress (CRS)-induced hair growth inhibition.

Dermoscopy Features of Cutaneous Warts.

Background: Cutaneous warts are benign epithelial skin lesions, caused by human papilloma virus (HPV). These warts can affect any part of the body, and the clinical presentation of cutaneous warts is highly variable, making it difficult to diagnose. Dermoscopy is a relatively new, non-invasive, diagnostic tool, which can assist in the identification of different types of skin lesions.

Curcumin induces G2/M arrest and triggers autophagy, ROS generation and cell senescence in cervical cancer cells.

Our study explored the tumor-suppressive effect of curcumin on cervical cancer cells. Cervical cancer is one of the most common cancers among women worldwide. Acquired resistance to chemotherapeutics and toxicity of such drugs has undermined the effectiveness of cervical cancer treatments.
