Efficient regeneration of NAD remains a significant challenge for oxidative biotransformations. In order to identify enzymes with higher activity and stability, a panel of NADH oxidases (Nox) was investigated in the regeneration of nicotinamide cofactors for the oxidation of hydroxymethyl furfural (HMF) to 5-hydroxymethyl-2-furancarboxylic acid (HMFCA). We present novel Nox that exhibit remarkable catalytic activities, elevated thermal and pH stabilities, and higher intrinsic flavin loadings, thus eliminating the need for external flavin addition.

We aimed to characterize baseline symptoms and impairments of patients attending outpatient LC rehabilitation.
Design: This study was a retrospective quality-improvement analysis.
The protracted form of COVID-19 known as 'long covid' was first described in 2020. Its symptoms, course and prognosis vary widely; some patients have a multi-system, disabling and prolonged illness. In 2021, ring-fenced funding was provided to establish 90 long covid clinics in England; some clinics were also established in Scotland and Wales.

Optical studies demonstrate the highly quantitative and reproducible photoinduced cyclic E/Z switching without decay of the complex. Accordingly and best to our knowledge, [Cu(1)](BF) constitutes the first reversibly photoswitchable (3d)-metallocycle based on azobenzene.
