Ulcerated Necrobiosis Lipoidica.

A 23-year-old Caucasian female, with type I diabetes mellitus, presented with a 7-month history of two painful yellowish-red plaques with ulcerated centre in the left leg. A diagnosis of ulcerated necrobiosis lipoidica (NL) was made and she was started on pentoxifylline 400 mg tid and tacrolimus ointment 0.1%. After four months of treatment with no improvement, the patient was proposed for hyperbaric oxygen therapy (HBOT). Overall, she received a total of 30 sessions of HBOT, after which the wounds healed completely. There have been no recurrences in the 14 months following resolution.

Nicotinamide riboside restores cognition through an upregulation of proliferator-activated receptor-γ coactivator 1α regulated β-secretase 1 degradation and mitochondrial gene expression in Alzheimer’s mouse models

Abstract Nicotinamide adenine dinucleotide (NAD)(+), a coenzyme involved in redox activities in the mitochondrial electron transport chain, has been identified as a key regulator of the lifespan-extending effects, and the activation of NAD(+) expression has been...
