Effect of obesity on ecocardiographic parameters and vertebral heart size (VHS) in cats

open access: yesSemina: Ciências Agrárias, 2020
The objective of this study was to correlate cardiovascular parameters with obesity in adult cats. Forty mixed-breed cats (20 obese and 20 controls) underwent echocardiographic measurements and thoracic radiography to establish a relationship between the

Application of NASTRAN for stress analysis of left ventricle of the heart [PDF]

open access: yes, 1975
Knowing the stress and strain distributions in the left ventricular wall of the heart is a prerequisite for the determination of the muscle elasticity and contractility in the process of assessing the functional status of the heart.

Exploration of Novel Biomarkers Through a Precision Medicine Approach Using Multi‐Omics and Brain Organoids in Patients With Atypical Depression and Psychotic Symptoms

open access: yesAdvanced Science, EarlyView.
This study examines major depressive disorder with atypical features and psychotic symptoms through a multi‐omics precision medicine approach. By integrating clinical assessments, WBC scRNA‐seq, plasma proteomics, and brain organoid models, it uncovers immune dysregulation, synaptic protein alterations, and stress‐sensitive neuronal changes.

Redox‐Responsive Tellurium‐Bridged Covalent Organic Frameworks/PEG Composites for Targeted Therapy of Diabetic Cardiomyopathy

open access: yesAdvanced Science, EarlyView.
This study unlocks the immense potential of COF@polymer nanocomposites as a multifunctional therapeutic platform for targeted drug delivery in diabetic cardiomyopathy. Abstract Diabetic cardiomyopathy, a major complication of diabetes, is strongly associated with elevated levels of glycated hemoglobin (HbA1c) and reactive oxygen species (ROS). However,

Organic Bulk‐Heterojunction‐Integrated Flexible Perovskite Photodetection Arrays for High‐Speed Broadband Optical Communication

open access: yesAdvanced Science, EarlyView.
A flexible broadband photodetector is realized by integrating a perovskite with an organic bulk‐heterojunction. It achieves high external quantum efficiency (EQE) (>80% visible, >60% near‐infrared (NIR)), ultralow dark current, and fast response, enabling self‐powered, high‐detectivity operation.

Piezo1 Upregulation in Monocyte‐Derived Macrophages Impairs Post‐Myocardial Infarction Cardiac Repair via Defective Efferocytosis and Enhanced Ferroptosis

open access: yesAdvanced Science, EarlyView.
This study reports early Piezo1 activation in bone marrow monocyte‐derived macrophages (MoMs) during myocardial infarction (MI), which governs the fate and function of recruited macrophages. The recruited MoMs with increased Piezo1 expression exhibit increased ferroptosis and defective efferocytosis, delayed clearance of dead cells and resolution of ...

Promoting Autophagy Mitigates Stress‐Induced Remodeling in Patient iPSC‐CMs with the Phospholamban R9C Mutation

open access: yesAdvanced Science, EarlyView.
The Phospholamban (PLN) R9C mutation reduces SERCA2a binding, increasing calcium recycling and baseline contractility. However, the excess of free PLN promotes pentamer formation, limiting phosphorylation and blunting β‐adrenergic signaling. Under cardiac stress, enhanced functional demands overwhelm proteostasis in PLN R9C cells, leading to misfolded ...
