A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

open access: yesAdvanced Science, EarlyView.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Regulatory adaptive status in determining the effectiveness of nebivololum and sotalolum in patients with hypertensive disease and paroxysmal atrial fibrillation

open access: yes, 2016
Aim: compare the effectiveness of treatment with nebivololum or sotalolum in patients with hypertensive disease (HD) and paroxysmal atral fibrillation (AF) taking into account quantitative evaluation of the regulatory adaptive status (RAS). Materials and

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

open access: yesExperimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Improving Nocturnal Non‐Invasive Positive Pressure Support Adherence in Children and Young Adults With Duchenne Muscular Dystrophy

open access: yesPediatric Pulmonology, Volume 61, Issue 8, August 2026.
ABSTRACT Background Patients with Duchenne muscular dystrophy (DMD) have progressive muscular weakness, respiratory decline and often have poor adherence to nocturnal non‐invasive positive airway pressure ventilation (NIPPV). Methods In 2020, we sought to increase nocturnal NIPPV adherence (≥ 4 h use overnight on at least 65% of nights) from 33% to 75%

Morphological changes in the arterial pressure waveform following hemodynamic therapies in critical care: A clinical proof‐of‐concept study in older adults

open access: yesPhysiological Reports, Volume 14, Issue 15, August 2026.
In 132 cardiac surgery patients, fluid bolus, norepinephrine, and dobutamine each produced a distinct, recognizable pattern in arterial waveform morphology (systolic area/downstroke time, diastolic area/time, augmented pressure), suggesting arterial waveform analysis is a promising tool for bedside hemodynamic decision support.

Recent Perspectives on Phytochemical Profile, Pharmacological Activities, and Industrial Applications of Guava (Psidium guajava)

open access: yesFood Safety and Health, Volume 4, Issue 3, Page 542-560, July 2026.
Psidium guajava leaves contain potent bioactive compounds like quercetin, myricetin, and triterpenoids that show antioxidant, antidiabetic, anti‐inflammatory, and anticancer effects. They act by modulating NF‐κB, PPARγ, and α‐glucosidase and by inducing apoptosis and cell cycle arrest.

Integrative Approach – New Level Knowledge of Functions: Opportunities and Prospects

open access: yes, 2012
In this article, the example of the mechanisms of heart rhythmogenesis in the intact organism is used to demonstrate the new capabilities provided by an integrative approach. It is shown that the rhythm is formed in the brain, transmitted to the heart in
