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.

Circadian regulation of skin pigmentation is essential for thermoregulation, ultraviolet (UV) protection, and synchronization of skin cell renewal. This regulation involves both cell-autonomous photic responses and non-cell-autonomous hormonal control, particularly through melatonin produced in a light-sensitive manner. Photosensitive opsins, cryptochromes, and melatonin regulate circadian rhythms in skin pigment cells.

Here, we aimed to comprehensively discuss walking in the context of an aging population; and identify and agree on a list of future research priorities and policy actions.
Methods: We followed a participatory approach and held a multidisciplinary two-day workshop on October, 2023 in Barcelona, Spain, with experts in the fields of aging and walking, and participants from the general public.
A new approach to children's work that prioritises resilience, well-being and agency: emerging findings from a 'cash plus' intervention in Bangladesh.
BMJ Paediatr Open
January 2025
BRAC Institute of Governance and Development, Dhaka, Bangladesh.
Background: Criticism of mainstream approaches to child labour is widespread and well-established. The Child Labour Action Research in South and Southeast Asia (CLARISSA) Cash Plus pilot sought to address these critiques through an innovative programme that prioritised the development of household resilience and well-being, and through increasing household capacity to make alternative choices around children's work.
Research: Funded by the UK's Foreign, Commonwealth and Development Office, this pilot delivered unconditional cash transfers (UCTs) and needs-based case management and community mobilising across an entire slum neighbourhood in Dhaka, Bangladesh.
Characterizing Oxidative Stress induced by Aβ Oligomers and the Protective Role of Carnosine in Primary Mixed Glia Cultures.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by cognitive decline and memory loss. A critical aspect of AD pathology is represented by oxidative stress, which significantly contributes to neuronal damage and death. Microglia and astrocytes, the primary glial cells in the brain, are crucial for managing oxidative stress and supporting neuronal function.
