FlowVN Trained on a Single Dataset Enables Rapid Reconstruction of Highly Accelerated 4D Flow MRI Across Multiple Sites

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 374-386, July 2026.
ABSTRACT Purpose The aim of this study is to evaluate a deep variational network, FlowVN, for the reconstruction of heavily undersampled 4D Flow MRI across multiple sites. Methods FlowVN was trained on fully sampled 4D Flow MRI datasets of healthy volunteers from one site. The model was tested on retrospective undersampled data (R = 6–22) of six normal

Networks of respiratory‐muscular coupling in exercise and fatigue in young adults

Physiological Reports, Volume 14, Issue 13, July 2026.
Amplitude‐amplitude cross‐frequency coupling (ACFC) is a novel method to quantify respiratory‐muscular dynamic interactions using breathing‐rate time series and EMG frequency‐band activity from distinct muscles. ACFC‐derived network maps show that respiratory‐muscular coupling increases with fatigue accumulation.

Evaluation of regulatory-adaptive status of pregnant women with type ii diabetes at 38-40 weeks of gestation

Кубанский научный медицинский вестник, 2015
Observations were performed on 20 healthy pregnant women and 84 women with diabetes on 38-40 weeks of gestation. All pregnant conducted obstetric examination, determined the glycemic profile, urinalysis, glucose, ketone bodies, acetone.

Sleep-stage dependence and co-existence of cardio-respiratory coordination and phase synchronization

Chaos: An Interdisciplinary Journal of Nonlinear Science
Interactions between the cardiac and respiratory systems play a pivotal role in physiological functioning. Nonetheless, the intricacies of cardio-respiratory couplings, such as cardio-respiratory phase synchronization (CRPS) and cardio-respiratory coordination (CRC), remain elusive, and an automated algorithm for CRC detection is lacking.

Circadian Immunity and Vascular Inflammation in Cardiovascular Disease Chronotherapy Windows: Time for a Re‐Assessment

Med Research, Volume 2, Issue 2, Page 236-279, June 2026.
ABSTRACT Circadian rhythms orchestrate cardiovascular physiology by regulating immune and inflammatory pathways. Disruption of these rhythms profoundly alters vascular homeostasis, thereby promoting the onset and progression of cardiovascular diseases (CVD).

Preclinical Quantitative In Vivo MRI Assessment of Exogenous Surfactant Pulmonary Distribution After Clinically Relevant Intratracheal Delivery

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
Quantitative in vivo contrast‐enhanced UTE MRI enables sensitive and precise mapping of pulmonary surfactant distribution, revealing peripheral localization and homogeneous distal penetration under physiological conditions. Comparison with ex vivo models highlights the role of physiological processes in surfactant retention.

THE INFLUENCE OF A CERTAIN PATHOLOGY ON THE REGULATORY-ADOPTIVE STATUS BY PATIENTS WITH ANGINA PECTORIS OF THE THIRD FUNCTIONAL CLASS

Кубанский научный медицинский вестник, 2015
By 89 patients with angina pectoris of the third functional class (FC), a regulatory-adoptive status by parameters of cardio-respiratory synchronism was determined. The sick were divided in four groups by the presence of a certain pathology. In the first

Integrative Advances in Equine Genomics From Reference Assemblies to Evolutionary History and Key Traits

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Horses are major domestic animals and cultural symbols that have accompanied humans for millennia. They underpin transport, agriculture, warfare and sport, and also provide a model for studying domestication, complex traits and adaptive evolution.

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...
