Foot ulcers increase morbidity and mortality in diabetic patients. Due to poor healing factors, surgical wound healing is questionable in diabetic patients. We report a patient with insulin-dependent diabetes mellitus, sensory neuropathy and microangiopathy, who had an infected stump of the right three middle digits and subsequent transmetatarsal amputation. The infected postoperative ulcer was...

Non-Langerhans cell, antigen-presenting T6- DR+ epidermal cells (EC) appear 3 days following broad band ultraviolet radiation exposure of human skin and are responsible for the increased antigen presentation capacity of EC seen 3 days after UV exposure. To determine the UV wavelengths that induce T6- DR+ EC, volar forearm skin of 10 human volunteers was irradiated in vivo with 4 minimal erythem...

BACKGROUND A novel short-wave ultraviolet light (UVC) pathogen reduction technology (THERAFLEX UV-Platelets; MacoPharma, Mouvaux, France) without the need of any additional photoactive reagent has recently been evaluated for various bacteria and virus infectivity assays. The use of UVC alone has on the one hand been shown to reduce pathogens but may, on the other hand, have some impact on the p...

In this work, we have tested a photocatalytic material consisting of core SiO2/Fe3O4 coated with TiO2 (Magnox) for plausible tertiary wastewater treatment. For this, pilot plant 45 L equipped an Ultraviolet light (UVC) lamp was employed to study the degradation model contaminant, enrofloxacin (ENR), as well water disinfection (elimination Escherichia coli and Clostridium perfringens). The influ...

Mitochondrial DNA (mtDNA) is different in many ways from nuclear DNA. A key difference is that certain types of DNA damage are not repaired in the mitochondrial genome. What, then, is the fate of such damage? What are the effects? Both questions are important from a health perspective because irreparable mtDNA damage is caused by many common environmental stressors including ultraviolet C radia...
