It is shown that the fundamental expression for the complex permittivity epsilons* of a dilute suspension of monodispersed, spherical particles, epsilons*=epsilone*(1+3phid*), where epsilone* is the complex permittivity of the suspending medium and d* the dipolar coefficient, is strictly valid for any value of the volume fraction phi of particles in the suspension, provided that d* is interpreted as the ensemble average value of the dipolar coefficient of the particles and is defined in terms of the macroscopic electric field in the suspension.

Location of Care Delivery for Pulmonary Arterial Hypertension in the United States.
Am J Respir Crit Care Med
January 2025
University of Utah, Division of Cardiovascular Medicine, Department of Medicine, Salt Lake City, Utah, United States.
Rationale: Guidelines recommend patients with pulmonary arterial hypertension (PAH) be referred to pulmonary hypertension (PH) centers, but little is known about where care is actually delivered in the United States (US).
Objectives: To use prescription patterns to estimate the proportion of PAH care delivered at US PH centers and explore factors associated with location of care.
Methods: This retrospective study analyzed claims from the Komodo database in adults who received ≥1 PAH prescription between March 2021 and February 2022.
Predicting nanofluid behavior in inflamed stenotic arteries: a neural network and finite element-Based analysis.

Department of Clinical Surgery, Cty Clin Emergency Hosp, Sibiu, Romania.
This study examines heat transfer and nanofluid-enhanced blood flow behaviour in stenotic arteries under inflammatory conditions, addressing critical challenges in cardiovascular health. The blood, treated as a Newtonian fluid, is augmented with gold nanoparticles to improve thermal conductivity and support drug delivery applications. A hybrid methodology combining finite element method (FEM) for numerical modelling and artificial neural networks (ANN) for stability prediction provides a robust analytical framework.

Background: Heart failure with preserved ejection fraction (HFpEF) represents a challenging cardiovascular condition characterized by normal systolic function but impaired diastolic performance. Despite its increasing prevalence, therapeutic options remain limited. This study investigated the metabolic effects of canagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, on cardiac function and energy metabolism in HFpEF.

Department of Radiology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, PR China.
Background: Different parotid tumors differ in terms of treatment strategies due to their distinct biological behaviors. Time-dependent diffusion magnetic resonance imaging (t-dMRI) can characterize and quantify the cytological indexes, and then aid the differential diagnosis of various tumors. However, the value of t-dMRI in the analysis of parotid gland tumors remains unclear.

Front Endocrinol (Lausanne)

Department of Industrial Engineering, Alma Mater Studiorum - University of Bologna, Bologna, Italy.
Introduction: Bone spinal metastases disrupt the bone homeostasis, inducing a local imbalance in the bone formation and/or resorption, with consequent loss of the structural optimisation of the vertebrae and increase of the risk of fracture. Little is known about the microstructure of the metastatic tissue, the microstructure of the tissue surrounding the lesion, and how it does compare with vertebrae with no lesions observed on the biomedical images. A comprehensive assessment of the microstructural properties of the entire vertebral body can be obtained with micro computed tomography.
