Article Abstract

The phytochemical profiles, antioxidant capacities, mineral composition, and antibacterial activities of () and () were explored through aqueous, ethanolic, and methanolic extractions. The extracts were analyzed for polyphenols, flavonoids, and tannins, and their antioxidant potential was assessed using the DPPH assay. UPLC-HRMS identified major bioactive compounds, including 6-gingerol and shogaol in , and piperine and piperlonguminine in . Mineral analysis showed that was particularly rich in essential elements, including calcium (Ca), magnesium (Mg), and iron (Fe). In antibacterial testing, demonstrated wider zones of inhibition against , whereas was more active at lower concentrations, showing MICs as low as 3.91 µg/mL against and . PCA analysis revealed strong correlations between phenolic content and biological effects. These results underscore the potential of both spices as effective natural agents for use in food preservation and health-promoting applications.

Epigallocatechin-3-gallate (EGCG), the predominant bioactive compound in green tea, has shown promise in lung cancer treatment; however, its molecular targets and antitumor mechanisms remain unclear. In this study, the therapeutic potential of EGCG against non-small cell lung (NSCLC) was evaluated, core targets were prioritized via network pharmacology, and molecular docking were employed to decipher the potential mechanism of action. Using bioinformatics, molecular docking, and functional enrichment analyses, 224 NSCLC-related targets were identified, with TP53, STAT3, AKT1, IL6, HSP90AA1, and JUN emerging as central hubs.

Department of Orthopedics, Beijing Anzhen Hospital, Capital Medical University, Beijing, China.

Diabetic foot ulcers (DFUs) represent a prevalent complication of diabetes, with a lifetime risk ranging from 15% to 25% among diabetic patients. Research indicates that anticoagulation plays a crucial role in the management of newly diagnosed cases of diabetic lower extremity atherosclerotic obliterative disease. However, in the present case, the patient developed dry gangrene in both toes after receiving vasodilator drugs during an emergency intervention for sudden aortic dissection.

Background: Musculoskeletal diseases (MSDs) are a common group of conditions involving bones, muscles, cartilage, ligaments, and nerves, which significantly impact patients' quality of life and ability to participate in society. Anthocyanins (ACNs), as phytochemicals, possess various pharmacological and biological activities, including anti-apoptotic, antioxidant, anti-inflammatory, and immunosuppressive properties. In recent years, ACNs have shown remarkable potential in improving MSDs.
