Clinical and Invasive Hemodynamic Correlates of the TAPSE/sPAP Ratio in Pulmonary Hypertension

Clinical Cardiology, Volume 49, Issue 11, November 2026.
Lower TAPSE/sPAP ratios are associated with adverse clinical characteristics, progressive right ventricular remodeling, and greater invasive hemodynamic impairment in pulmonary hypertension. TAPSE/sPAP provides a simple, noninvasive marker for assessing RV–pulmonary arterial uncoupling and bedside hemodynamic risk stratification.

Fermented Noni Juice Supplementation Attenuates Heart Failure Development in Mice: Involvement of the Pentose Phosphate Pathway

Food Frontiers, Volume 7, Issue 6, November 2026.
ABSTRACT Morinda citrifolia L., commonly known as Noni, is a traditional medicinal plant that has long been utilized in various cultures for its anti‐inflammatory and antioxidant properties. Heart failure (HF) is a significant and growing public health concern worldwide that is characterized by substantial morbidity, mortality, and healthcare costs ...

Spectrogram-Based Non-Contact RRI Estimation by Accurate Peak Detection Algorithm

IEEE Access, 2018
Demands for vital sign monitoring are increasing in the field of health care. In particular, the R-R Interval (RRI) estimation has been studied extensively, since the RRI variation is highly related with the stress of a subject.

Pulmonary Hamartoma Diagnosed by Transbronchial Mediastinal Cryobiopsy Additional to Needle Aspiration: A Case Report

Respirology Case Reports, Volume 14, Issue 11, November 2026.
This report presents a diagnostically challenging pulmonary hamartoma manifesting as a peribronchial lesion mimicking interlobar lymphadenopathy without typical radiological hallmarks. Limited tissue acquired via EBUS‐TBNA precluded a conclusive diagnosis, whereas supplementary transbronchial mediastinal cryobiopsy yielded larger, structurally ...

The Senokine Gas6 Promotes Aortic Valve Calcification Through CaMKII–DRP1–Mediated Terminal Scission of Mitochondrial‐Derived Vesicles

Aging Cell, Volume 25, Issue 11, November 2026.
In age‐associated calcific aortic valve disease (CAVD), human valve tissues and calcifying human valvular interstitial cells (hVICs) exhibit senescence‐associated features, while calcifying hVICs hypersecrete mitochondrial‐derived vesicles (MDVs). Donut‐shaped mitochondria serve as physical platforms for MDV budding, whereas Gas6 promotes Ca2+–CaMKII ...

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, Volume 293, Issue 21, Page 6444-6466, November 2026.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

Portal Vein Doppler in Venous Congestion: Incremental Value, Dynamic Decongestion Monitoring, and Clinical Decision-Making in Heart Failure [PDF]

Studies in Multidisciplinary Medical Research
Systemic venous congestion in heart failure (HF) is an active driver of organ dysfunction and adverse outcomes. Conventional assessment tools lack sensitivity for subclinical congestion and specificity for venous hypertension.

Linking dynamic cerebral autoregulation and inhibitory executive function: Role of modifiable behaviours

Experimental Physiology, Volume 111, Issue 11, Page 5041-5051, 1 November 2026.
Abstract Dynamic cerebral autoregulation (dCA) stabilises cerebral blood flow (CBF) against rapid fluctuations in perfusion pressure and may serve as a key physiological mediator of cognitive function. Inhibitory executive function, a core domain essential for goal‐directed behaviour, is influenced by modifiable lifestyle factors such as physical ...
