Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

Hydrodynamization of charm quarks in heavy-ion collisions [PDF]

EPJ Web of Conferences
Heavy quarks (i.e. charm and beauty) in heavy-ion collisions are initially produced out of kinetic equilibrium via hard partonic scattering processes.

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

Experimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

Galectin‐3 plasma levels are associated with left atrial contractile function in long‐distance runners

Experimental Physiology, EarlyView.
Abstract High‐intensity endurance exercise induces myocardial remodelling as an adaptive response to sustained volume overload, but excessive cumulative training might also favour deleterious cardiac remodelling, including atrial fibrosis. Whether acute marathon running engages circulating fibrosis‐related biomarkers and whether these biomarkers track ...

Enhancement of new physics signal sensitivity with mistagged charm quarks

Physics Letters B, 2016
We investigate the potential for enhancing search sensitivity for signals having charm quarks in the final state, using the sizable bottom-mistagging rate for charm quarks at the LHC.

Effects of dietary nitrate supplementation on peak oxygen uptake following 10 days of Ramadan fasting in healthy adults

Experimental Physiology, EarlyView.
Abstract Ramadan is a sacred religious practice observed by Muslims that involves abstaining from food and water from sunrise to sunset for 1 month. Prior work has reported that peak oxygen uptake (V̇O2peak${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{peak}}}}$) can decline during Ramadan in parallel with reduced physical activity.

Heavy-heavy and heavy-light quarks interactions generated by QCD vacuum

EPJ Web of Conferences, 2017
The QCD vacuum is populated by instantons that correspond to the tunneling processes in the vacuum. This mechanism creates the strong vacuum gluon fields.

The direct coupling of light quarks to heavy di-quarks

Physics Letters B, 2019
In the limit mQ>mQvrel>mQvrel2≫ΛQCD hadronic states with two heavy quarks Q should be describable by a version of HQET where the heavy quark is replaced by a di-quark degree of freedom.

The acute effects of exercise intensity and inorganic nitrate supplementation on the Buckberg ratio in postmenopausal females

Experimental Physiology, EarlyView.
Abstract Menopause increases coronary heart disease risk, in part through reduced oestrogen‐mediated nitric oxide (NO) bioavailability. The Buckberg ratio, an index of myocardial oxygen supply–demand balance, in which higher values reflect more favourable myocardial perfusion, is lower in postmenopausal females (PMFs) than in age‐matched males.
