Ultrasound-Triggered Oxygen Release System for Accelerating Wound Healing of Diabetic Foot Ulcers.

Diabetic foot ulcer (DFU) is a common complication of chronic diabetes mellitus. Oxygen plays a critical role in the healing process of DFU wounds by promoting cell migration and neovascularization. However, clinical hyperbaric oxygen (HBO) therapy predominantly uses systemic oxygen administration, posing challenges in inadequate DFU local oxygen penetration and potential ectopic organs oxygen toxicity.

Current Status and Future Suggestions for Innovative Drug Research and Development in China.

In recent years, with the policy reform of new drug review and approval, China has ushered in a surge of innovative drug development. Based on the Pharnexcloud database and the Pharmcube database, we analyzed the innovative drugs approved for marketing and entered clinical trials in China, sorted out the major research and development (R&D) institutions and enterprises, the distribution of innovative drug target types, and the primary therapeutic areas of the approved innovative drugs, and compared with the global innovative drug R&D landscape. Since 2020, China's innovative drug development has shown a rapid growth trend, with intense competition among biopharmaceutical companies, and the emergence of a number of leading biopharmaceutical enterprises.

The predictive value of anti-IFI16 antibodies for the development or persistence of digital ulcers in systemic sclerosis.

To evaluate the association of anti-IFI16 antibodies with peripheral vasculopathy and the predictive value of anti-IFI16 antibodies for the development or persistence of digital ulcers (DPDU) in SSc. A total of 42 SSc patients and 42 age- and sex-matched healthy controls were enrolled. Anti-IFI16 antibodies were examined by ELISA.

Correlation of Histologic Features with Gene Alterations in Pleural Mesothelioma.

Histologic features, including architectural patterns, cytologic features, and 2021 World Health Organization nuclear grade have been shown to have prognostic significance in epithelioid diffuse pleural mesothelioma (DPM). Biphasic and sarcomatoid DPM, regardless of morphology, have worse outcomes. These prognostic findings are well-established but correlation of architectural patterns, cytologic features, and nuclear grade with genetic alterations has not been well studied.

Enzyme-assisted Rosa davurica mitigates UV-induced skin photodamage by modulating apoptosis through Nrf2/ARE and MAPK/NF-κB pathways.

Exposure to UV irradiation results in abnormal, extensive apoptosis of skin cells. This excessive cell death can promote inflammation and alter the microenvironment, increasing the risk of skin cancer. Despite extensive research, few materials are effective at simultaneously protecting against both UVA and UVB irradiation.
