Using Multiple Diagnostic Methods for Occupational Asthma Assessment

open access: yesThe Clinical Respiratory Journal, Volume 20, Issue 5, May 2026.
PC20 variability demonstrated higher diagnostic accuracy than PEFR monitoring in occupational asthma (OA), with a sensitivity of 90% and specificity of 92%. PEFR alone resulted in a 22.2% misclassification rate. Incorporating PC20 variability into diagnostic evaluation may reduce misdiagnosis and improve clinical outcomes in high‐exposure settings ...

PSR B1257+12: a quark star with planets?

open access: yes, 2007
A recent observation has shown that PSR B1257+12 could have quite small X-ray emitting area, only about 2000 m$^2$, which is more than three orders smaller than the canonical polar cap size.

Hypohydration Increases Heart Rate Despite Preserved Hemodynamic Compensation During Blood Flow Restricted Exercise

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.
ABSTRACT During blood flow restriction (BFR) exercise, blood becomes sequestered in the active limbs due to impeded venous return, contributing to central hypovolemia. Dehydration also reduces blood volume and can exacerbate the ability of the cardiovascular (CV) system to defend against CV stressors, such as exercise and orthostatic stress.

Quark deconfinement and neutrino trapping in compact stars

open access: yes, 2004
We study the role played by neutrino trapping on the hadron star (HS) to quark star (QS) conversion mechanism proposed recently by Berezhiani and collaborators.

In‐Field Validity and Inter‐Unit Variability of Metabolic Carts During Simulated Exercise

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.
ABSTRACT The present study had three main objectives: (a) to evaluate the in‐field validity of different commercially available cardiopulmonary exercise testing (CPET) systems when used by end‐users following typical calibration procedures, (b) to measure the variability in accuracy among identical CPET units, and (c) to explore the relationship ...

Deconfinement transition in protoneutron stars: analysis within the Nambu-Jona-Lasinio model

open access: yes, 2010
We study the effect of color superconductivity and neutrino trapping on the deconfinement transition of hadronic matter into quark matter in a protoneutron star. To describe the strongly interacting matter a two-phase picture is adopted. For the hadronic

Bed rest decreases resting skeletal muscle O2 uptake and resting energy expenditure in young and elderly subjects

open access: yesExperimental Physiology, Volume 111, Issue 5, Page 2599-2612, 1 May 2026.
Abstract A decrease in resting muscle O2 uptake (V̇O2m${\dot V_{{{\mathrm{O}}_2}{\mathrm{m}}}}$) described during bed rest (BR) could determine a decreased whole‐body resting energy expenditure (REE), potentially useful during prolonged spaceflights. Two groups of recreationally active men (young [Y], n = 8, age 23 ± 5 years; elderly [E], n = 10, age ...

SGR 0418+5729 as an evolved Quark-Nova compact remnant

open access: yes, 2011
Soft gamma repeaters and anomalous X-ray pulsars are believed to be magnetars, i.e. neutron stars powered by extreme magnetic fields, B~10^(14)-10^(15) Gauss.

Influence of age and biological sex on sweating in children exercising in warm and hot environments with comparison to adults

open access: yesThe Journal of Physiology, Volume 604, Issue 10, Page 3786-3801, 15 May 2026.
Abstract figure legend Local sweating response and sweating onset of boys, girls, adult females and adult males during treadmill walking at a fixed metabolic heat production per body surface area (300 W·m−2) in warm and hot environments. Bayesian hierarchical modelling showed no meaningful sex or age differences in local sweating responses or onset ...

Hybrid stars that masquerade as neutron stars

open access: yes, 2004
We show that a hybrid (nuclear + quark matter) star can have a mass-radius relationship very similar to that predicted for a star made of purely nucleonic matter. We show this for a generic parameterization of the quark matter equation of state, and also
