Open AccessProduction and persistence of specific antibodies in COVID-19 patients with hematologic malignancies: role of rituximab
The ability of patients with hematologic malignancies (HM) to develop an effective humoral immune response after COVID-19 is unknown. A prospective study was performed to monitor the immune response to SARS-Co...

Calf and shin muscle oxygenation patterns and femoral artery blood flow during dynamic plantar flexion exercise in humans
The effects of dynamic plantar flexion exercise [40, 60, and 80 contractions·min–1 (cpm)] on calf and shin muscle oxygenation patterns and common femoral artery blood flow ( $$ \dot Q_{{\rm fa}...

Human motor-cortex oxygenation changes induced by cyclic coupled movements of hand and foot
Near-infrared spectroscopy (NIRS) was used to assess human motor-cortex oxygenation changes in response to cyclic coupled movements of hand and foot. Using a highly sensitive NIRS instrument, we showed that it...

Influence of Repeated Ischaemia/Reperfusion Cycles (Ischaemic Preconditioning) on Human Calf Energy Metabolism by Simultaneous Near Infrared Spectroscopy, 31P-NMR and 23Na-NMR Measurements
Ischaemic preconditioning (IP) (Lawson & Downey, 1993) with one or more cycles, consisting each of a short period of ischaemia followed by equal periods of reperfusion, improves myocardial tolerance to a subse...

Measurement of Cytochrome Oxidase Redox State by Near Infrared Spectroscopy
Although near infrared spectroscopy (NIRS) is primarily used to probe changes in oxyhaemoglobin (HbO2) and deoxyhaemoglobin (dHb) concentrations, it has long been realised that there is a significant oxygen-conce...

Influence of the Treadmill Speed/Slope on Quadriceps Oxygenation During Dynamic Exercise
One of the main obstacles that has restricted “in vivo” studies of skeletal muscle metabolism during exercise has been the invasive nature of tissue biopsy and the high cost of phosphorus nuclear magnetic resonan...

Nitroxides as metabolic and EPR imaging probes in biological model systems
Nitroxides are unusually stable free radicals and sensitive “reporters” of the chemico-physical environment which surround them. The term “reporter group” was used to indicate this property, later the term spi...

97 ELECTRON PARAMAGNETIC RESONANCE (EPR) MONITORING OF ASCURBATE FREE RADICAL (A*) AS MARKER OF INCREASED IRON-MEDIATED OXIDATIVE DAMAGE (MOD) IN PLASMA OF NEONTES
In common neonatal disorders (hemolytic disease, asphyxia, hypoperfusion) as well as in red cell transfusion the oxidative risk can increase, as free iron is released from damaged tissues and promotes conversi...
