A comparative study is disclosed that seeks to highlight the current limitations and challenges that exist in the field of atom-transfer C-H oxidations. State-of-the-art methods are benchmarked in order to showcase clear differences and similarities. A novel Mn-mediated method for C-H oxidation is disclosed that serves as a rapid and simple method for aliphatic C-H hydroxylation. Finally, two methods that allow for C-H oxidation in the presence of pyridine-containing substrates are studied, something that is rare in the field but of great interest to the chemical community.

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.

Morphea is a chronic inflammatory fibrosing disorder. Since fibrosis is the hallmark of both scars and morphea, our attention was raised for the possible use of Fractional Ablative CO lasers and microneedling as treatment modalities for morphea. To compare the efficacy and safety of Fractional Ablative CO lasers and microneedling in the treatment of morphea.

This study aims to explore the measurement agreement between direct and indirect health utility measures in four chronic dermatological conditions (atopic dermatitis, hidradenitis suppurativa, pemphigus, psoriasis). Outpatients survey data collected between 2015 and 2021 were analysed. Health-related quality of life (HRQoL) outcome measures included time trade-off (TTO), EQ-5D-5L and Dermatology Life Quality Index (DLQI).

Both the surgical non-cultured melanocyte-keratinocyte transplant procedure (MKTP) and intradermal injection of 5-Fluorouracil (5-FU) are effective in the treatment of vitiligo. Intrablisters injection of MKTP was done in one study with better results than MKTP application after ablative CO2 laser of the reciepient area. However, intrablister injection of 5-FU was not done before.
