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

open access: yesExperimental 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 ...

Search for single production of vector-like quarks decaying into Wb in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
A search for singly produced vector-like quarks Q, where Q can be either a T quark with charge +2/3 or a Y quark with charge −4/3, is performed in proton–proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity

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

open access: yesExperimental 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.

Impact of living and training at low altitude for several years on endurance performance at higher altitude: Myth or reality

open access: yesExperimental Physiology, EarlyView.
Abstract The physiological adaptations of long‐term high‐altitude residents without high‐altitude genetic ancestry remain poorly characterized. This study investigated whether permanent residence at low altitude (1200 m) influences performance at higher altitude (2500 m). We compared exercise responses at 2500 m in endurance‐trained athletes living for

On the top-quark width measurement using a combination of resonant and non resonant cross sections.

open access: yesEPJ Web of Conferences, 2017
Top quark width measurement is important and complex task. Most measurements are done in assumption of the SM top quark interactions. We would like to discuss model independent way of measuring the top quark width.

Heavy-light meson spectroscopy and Regge trajectories in the relativistic quark model [PDF]

open access: yes, 2009
The masses of the ground, orbitally and radially excited states of heavy-light mesons are calculated within the framework of the QCD-motivated relativistic quark model based on the quasipotential approach.

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

open access: yesExperimental 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.

Bridging the chiral symmetry and confinement with singularity

open access: yesPhysics Letters B, 2020
We consider a holographic quark model where the confinement is a consequence of the quark condensate. Surprisingly, the equation of motion of our holographic model can be mapped to the old spin-less bag model.

The newly observed open-charm states in quark model [PDF]

open access: yes, 2010
Comparing the measured properties of the newly observed open-charm states D(2550), D(2600), D(2750), D(2760), Ds1(2710), DsJ(2860), and DsJ(3040) with our predicted spectroscopy and strong decays in a constituent quark model, we find that (1) the D(2 1S0)
