Refining Residual Ischemic Stroke Risk in Anticoagulated Atrial Fibrillation Using Index Outpatient LA Diameter: The CHA2DS2‐VALa Score

Journal of Cardiovascular Electrophysiology, EarlyView.
In anticoagulated atrial fibrillation, residual ischemic stroke risk persists despite guideline‐directed therapy. In this single‐center cohort, an enlarged index outpatient left atrial diameter independently predicted stroke and improved risk stratification when added to CHA2DS2‐VA (CHA2DS2‐VALa), supporting a simple, clinically implementable ...

Ionospheric disturbances associated with the eruption of Mt. Asama observed by TEC data and HF Doppler sounding

Earth, Planets and Space
Mt. Asama, Nagano Prefecture, Japan, erupted at 11:02 UT on September 1st, 2004. Ionospheric disturbances associated with this eruption were detected using TEC data and HF Doppler observations. It has already been reported that the TEC data obtained from

Small muscle mass aerobic exercise in health and disease: Unique insights into muscle vascular and metabolic control and performance

Experimental Physiology, EarlyView.
Abstract Studies of small muscle mass exercise (SMME) have revealed that the peripheral O2 transport–utilization cascade is a dynamically regulated system in which perfusive and diffusive components can be selectively amplified, redistributed and mechanically limited depending on contraction pattern, recruitment strategy and intramuscular pressure ...

The dynamic Auger-Doppler effect in HF and DF: control of fragment velocities in femtosecond dissociation through photon energy detuning

, 2002
The Auger-Doppler effect in the experimental spectra of HF and DF is presented. and the dynamics of ultra-fast dissociation in the core-excited state are discussed.

Clearance of p16‐positive cardiac cells improves age‐related cardiac remodeling in mice

Experimental Physiology, EarlyView.
Abstract Senescent cells are characterized by expression of markers like p16 and secretion of profibrotic and proinflammatory factors. The role of cellular senescence in age‐related cardiac remodeling and dysfunction is incompletely understood. This study aimed to: (i) evaluate the effect of p16‐ positive cell clearance on cardiac function and ...

Simultaneous acquisition of maternal and dual‐fetal electrocardiography with maternal haemodynamic monitoring in anaesthetized pregnant rats

Experimental Physiology, EarlyView.
Abstract Experimental approaches that acquire maternal haemodynamics together with direct cardiac signals from more than one fetus remain limited. We developed a standardized in vivo method for simultaneous acquisition of maternal ECG, maternal arterial blood pressure and ECGs from two fetuses in anaesthetized late‐gestation Sprague–Dawley rats.

Usefulness of clinical predictors for preoperative screening of deep vein thrombosis in hip fractures

BMC Musculoskeletal Disorders, 2017
Background Recent studies showed that preoperative deep vein thrombosis (DVT) was common after hip fracture (HF), and preoperative DVT screening has been recommended for preventing the fatal DVT-related complications, especially in elderly HF patients ...

Asymptomatic Cardiotoxicity After High‐Dose Anthracycline Treatment in Sarcoma Patients Assessed by Biomarkers and Echocardiography

International Journal of Cancer, Volume 159, Issue 11, Page 2755-2765, 1 December 2026.
ABSTRACT Treatment of sarcoma includes high‐dose anthracyclines, which can cause cardiotoxicity. This study assesses the correlation of cardiac biomarkers and echocardiographic parameters on asymptomatic cardiotoxicity in sarcoma patients treated with anthracyclines.
