Concentric ring optical traps for orbital rotation of particles

Optical vortices (OVs), as eigenmodes of optical orbital angular momentum, have been widely used in particle micro-manipulation.Recently, perfect optical vortices (POVs), a subclass of OVs, are gaining increasing interest and becoming an indispensable tool in optical trapping due to their unique property of topological charge-independent vortex rad

Intravenous nicotinamide riboside elevates mouse skeletal muscle NAD+ without impacting respiratory capacity or insulin sensitivity

Summary: In clinical trials, oral supplementation with nicotinamide riboside (NR) fails to increase muscle mitochondrial respiratory capacity and Dryer Thermistor insulin sensitivity but also does not increase muscle NAD+ levels.This study tests the feasibility of chronically elevating skeletal muscle NAD+ in mice and investigates the putative effe

Center of Isotope: actions for the benefit of public health

To commemorate the 500th anniversary of the city of Havana, the Isotope Center reviews its activity since its creation.The production of radionuclidemarked compounds and other radiochemical work at the Seat Slide Institute of Nuclear Physics, inaugurated in 1969, stimulated the applications of open radioactive sources, which can be considered as th
