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 ...

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

The Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...

A genetic algorithm simheuristic for solving the stochastic project portfolio selection problem with portfolio reliability constraints

International Transactions in Operational Research, Volume 33, Issue 6, Page 4039-4071, November 2026.
Abstract In response to the increasing complexity of modern products, dynamic markets, and intensified competition, project‐based organizations are actively seeking methodologies to efficiently manage their expanding project portfolios. This paper analyzes the project portfolio selection problem in uncertain environments. Despite recent advances in the

Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, Volume 111, Issue 9, Page 4223-4234, 1 September 2026.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Feasibility of superimposed supine cycling and lower body negative pressure as an effective means of prolonging exercise tolerance in individuals experiencing persisting post‐concussive symptoms: Preliminary results

Experimental Physiology, Volume 111, Issue 6, Page 3055-3068, 1 June 2026.
Abstract To examine the feasibility, utility and safety of superimposed lower body negative pressure (LBNP) and tilt during supine cycling in individuals suffering from persisting post‐concussive symptoms (PPCS). Eleven individuals aged 17–31 (6 females/5 males) participated in two randomized separate visits, 1 week apart.

A cascade model of dynamic cerebral autoregulation

The Journal of Physiology, Volume 604, Issue 10, Page 3763-3785, 15 May 2026.
Abstract figure legend This study examined a two‐component cascade model linking upstream dynamic cerebral autoregulation (dCA) with downstream microvascular function (MF) to explain how blood pressure oscillations influence cortical oxygenation. Transfer function analysis in the frequency domain was applied to quantify H1(f) (MAP→CBFV; dCA), H2(f ...
