UV-A exposure is a major risk factor for melanoma, nonmelanoma skin cancer, photoaging, and exacerbation of photodermatoses. Since people spend considerable time in cars daily, inadequate UV-A attenuation by car windows can significantly contribute to the onset or exacerbation of these skin diseases. Given recent market trends in the automobile industry and known impact of car windows on cumulative lifelong UV damage to the skin, there is a need to comparatively evaluate UV transmission across windows in electric vehicles (EV), hybrid vehicles (HV), and gas vehicles (GV) as well as variability based on year of manufacture and mileage to inform car manufacturers and consumers of the potential for UV exposure to the skin based on vehicle.

X-ray Responsive Antioxidant Drug-Free Hydrogel for Treatment of Radiation Skin Injury.

ACS Appl Mater Interfaces

January 2025

State Key Laboratory of Advanced Medical Materials and Devices, Tianjin Key Laboratory of Radiation Medicine and Molecular Nuclear Medicine, Key Laboratory of Radiopharmacokinetics for Innovative Drugs, Tianjin Institutes of Health Science, Institute of Radiation Medicine, Chinese Academy of Medical Sciences & Peking Union Medical College, Tianjin 300192, P. R. China.

Radiotherapy (RT) is widely applied in tumor therapy, but inevitable side effects, especially for skin radiation injury, are still a fatal problem and life-threatening challenge for tumor patients. The main components of topical radiation protection preparations currently available on the market are antioxidants, such as SOD, which are limited by their unstable activity and short duration of action, making it difficult to achieve the effects of radiation protection and skin radiation damage treatment. Therefore, we designed a drug-free antioxidant hydrogel patch with encapsulated bioactive epidermal growth factor (EGF) for the treatment of radiation skin injury.

Advances in the relationship of immune checkpoint inhibitors and DNA damage repair.

Curr Res Transl Med

January 2025

Cancer Center, Beijing Friendship Hospital, Capital Medical University, Beijing, PR China. Electronic address:

Cancer immunotherapy, alongside surgery, radiation therapy, and chemotherapy, has emerged as a key treatment modality. Immune checkpoint inhibitors (ICIs) represent a promising immunotherapy that plays a critical role in the management of various solid tumors. However, the limited efficacy of ICI monotherapy and the development of primary or secondary resistance to combination therapy remain a challenge.

Magnetic resonance imaging (MRI) is one of the most commonly used tools in neuroscience. However, it implies exposure to high noise levels. Exposure to noise can lead to temporary or permanent hearing loss, especially when the exposure is long and/or repeated.

Oral iron sulfide prevents acute alcohol intoxication by initiating the endogenous multienzymatic antioxidant defense system.

Sci Adv

January 2025

State Key Laboratory of Medicinal Chemical Biology, College of Pharmacy, Nankai University, Haihe Education Park, 38 Tongyan Road, Tianjin 300353, People's Republic of China.

Acute alcohol intoxication could cause multiorgan damage, including nervous, digestive, and cardiovascular systems, and in particular, irreversible damage to the brain and liver. Emerging studies have revealed that the endogenous multienzymatic antioxidant defense system (MEAODS) plays a central role in preventing oxidative stress and other toxicological compounds produced by alcohol. However, few available drugs could quickly regulate MEAODS.
