On the metric dimension of imprimitive distance-regular graphs

, 2016
A resolving set for a graph $\Gamma$ is a collection of vertices $S$, chosen so that for each vertex $v$, the list of distances from $v$ to the members of $S$ uniquely specifies $v$.

Cardiac dysfunction during adverse maternal outcomes in hypertensive disorders of pregnancy

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 2, Page 280-287, February 2026.
In pregnancies complicated by hypertensive disorders, peripartum adverse maternal outcomes are associated with diastolic cardiac dysfunction. Elevated E/e' ratio and left atrial volume index highlight the need for targeted cardiovascular monitoring and long‐term follow‐up.

Predicting Reduced Left Ventricular Ejection Fraction in Patients With ST‐Elevation Myocardial Infarction: Role of the Quick Forrester Classification

Acute Medicine &Surgery, Volume 13, Issue 1, January/December 2026.
This study develops the quick Forrester Classification (QFC), a novel risk stratification tool based on the respiratory rate and serum lactate levels upon hospital arrival in patients with ST‐elevation myocardial infarction. QFC Class‐4 identifies individuals at high risk for the reduced left ventricular ejection fraction and the need for mechanical ...

Apical Sparing of Longitudinal Strain and Myocardial Fibrosis in Hypertensive Patients and Spontaneously Hypertensive Rats: Based on Speckle Tracking and Histological Analysis

Clinical Cardiology, Volume 49, Issue 1, January 2026.
Hypertensive cardiac hypertrophy shows a “basal‐damage, apical‐sparing” pattern in strain and fibrosis. This apical sparing correlates with diastolic dysfunction and hypertrophy progression, highlighting its value as an observable clinical hallmark of adverse remodeling. ABSTRACT Background This study aimed to investigate regional myocardial strain and

A model of blood flow in the mesenteric arterial system [PDF]

, 2007
Background There are some early clinical indicators of cardiac ischemia, most notably a change in a person's electrocardiogram. Less well understood, but potentially just as dangerous, is ischemia that develops in the gastrointestinal system.

High Demand Loading Conditions and Their Effect on Polyethylene Stresses in Lumbar Total Joint Replacement: Implications for Spine Wear Protocols

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT The study aimed to compare contact stresses for a novel lumbar total joint replacement (LTJR) during a standardized duty cycle with elevated loading conditions. A finite element model (FEM) of an LTJR was developed, verified, and validated using the ASME V&V40 standard. Simulations were performed using LS‐Dyna. Increasing the axial loading for

Adaptation of right ventricular function following tricuspid transcatheter edge‐to‐edge repair

ESC Heart Failure, Volume 12, Issue 6, Page 4451-4462, December 2025.
Right ventricular remodelling following tricuspid transcatheter edge‐to‐edge repair. After T‐TEER, most patients either maintain or decrease their RVEF, while only a minority experience an increase. Patients with increased RVEF were associated with TR worsening and worse prognosis.

Low‐dose digoxin improves cardiac function in patients with heart failure, preserved ejection fraction and atrial fibrillation – the RATE‐AF randomized trial

European Journal of Heart Failure, Volume 27, Issue 12, Page 2869-2878, December 2025.
Summary of the change in left ventricular systolic and diastolic parameters from baseline to 12 months in patients with permanent atrial fibrillation (AF) and a left ventricular ejection fraction (LVEF) ≥50%. P‐values indicate the significance of the adjusted mean difference of the parameters at 12 months between the beta‐blocker and digoxin arm. E/e′,
