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

open access: yesExperimental 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.

The spectral radius of bicyclic graphs with prescribed degree sequences

open access: yes, 2010
Restricted to the bicyclic graphs with prescribed degree sequences, we determine the (unique) graph with the largest spectral radius with respect to the adjacency ...

On the spectral radius of bicyclic graphs

open access: yesBulletin: Classe des sciences mathematiques et natturalles, 2005
The authors determine the graph with maximal spectral radius among connected bicyclic graphs of order \(n\), possessing \(k\) pendent vertices. This is the graph having two triangles with a common vertex at which \(k\) paths of almost equal length are attached.

Endocrine and androgenic response to altitude training in professional cyclists

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).

Signed bicyclic graphs minimizing the least Laplacian eigenvalue

open access: yes, 2018
A signed graph is a pair (G,sigma), where G is a graph and sigma is the sign function on the edges of G. For a signed graph we consider the Laplacian matrix defined as L=D-A, where D is the matrix of vertices degrees of G and is the (signed) adjacency ...

On the Extremal Weighted Mostar Index of Bicyclic Graphs

open access: yesAxioms
Let G be a simple connected graph with edge set E(G) and vertex set V(G). The weighted Mostar index of a graph G is defined as w+Mo(G)=∑e=uv∈E(G)(dG(u)+dG(v))|nu(e)−nv(e)|, where nu(e) denotes the number of vertices closer to u than to v for an edge uv ...

Post‐exercise ketone supplementation improves endurance performance and mitochondrial adaptations during an 8‐week endurance training intervention

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐eight trained males completed 8 weeks of supervised indoor cycling training, receiving post‐exercise and pre‐sleep ketone monoester (KE, n = 14) or isocaloric placebo (CON, n = 14). Both groups improved 30 min time‐trial performance with training, but KE achieved a 4% higher power output than CON at the end of the training

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

open access: yesMedicinal Research Reviews, Volume 46, Issue 4, Page 1173-1229, July 2026.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...

Inclusive cycle training: Using the COM‐B model to examine the attitudes, perceptions and behaviours of cycle instructors

open access: yesJournal of Research in Special Educational Needs, Volume 26, Issue 3, July 2026.
Abstract This is the first study to comprehensively consider cycle instructor knowledge, motivation and behaviour when teaching children with disabilities. Using a prospective design, we used a questionnaire to measure COM‐B components before (N = 845), immediately after (N = 480) and 6 months after (N = 63) an online course for instructors.
