Effect of prolonged space flight on cardiac function and dimensions [PDF]

open access: yes
Echocardiographic studies were performed preflight 5 days before launch and on recovery day and 1, 2, 4, 11, 31 and 68 days postflight. From these echocardiograms measurements were made.

Tapered Pillar Design for High‐Precision Force Readout in Miniaturized Engineered Heart Tissues From Human Pluripotent Stem Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered heart tissues (EHTs) are a valuable approach in capturing human cardiac physiology and drug responses in vitro. Here, a novel tapered pillar design is developed in an EHT platform to confine tissues in a predefined position‐ at the middle of the pillar height.

Engineering Extracellular Microenvironments: The Impact of Fibrous Materials on Cell Behavior

open access: yesAdvanced Healthcare Materials, EarlyView.
Fibrous structures are key elements of the native extracellular matrix and crucial for directing cell behavior. This review discusses how fiber properties such as composition, diameter, and alignment affect cell responses in 2D and 3D systems. Strategies for integrating fibrous cues into engineered tissues are highlighted, and future directions for ...

Effect of propranolol on regional myocardial function in anesthetized open-chest dogs with myocardial ischemia [PDF]

open access: yes, 1978
Effects of propranolol on ischemic segmental function were studied in anesthetized open-chest dogs. Two segment-length gauges were used for measuring the regional myocardial function: one was sutured on to the left ventricular surface perfused by the ...

Seeing inside the Body Using Wearable Sensing and Imaging Technologies

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores wearable technologies for noninvasive internal health monitoring. It categorizes approaches into indirect sensing (e.g., bioelectrical and biochemical signals) and direct imaging (e.g., wearable ultrasound and EIT), highlighting multimodal integration and system‐level innovation toward personalized, continuous healthcare.

Cardioprotective effects of exercise training: the importance of nitric oxide [PDF]

open access: yes, 2008
Left ventricular remodeling after myocardial infarction is a compensatory mechanism, which serves to restore left ventricular pump function to normal levels.

Estimation of elastic and viscous properties of the left ventricle based on annulus plane harmonic behavior [PDF]

open access: yes, 2006
Assessment of left ventricular (LV) function with an emphasis on contractility has been a challenge in cardiac mechanics during the recent decades. The LV function is usually described by the LV pressurevolume (P-V) diagram. The standard P-V diagrams

Designing the Next Generation of Biomaterials through Nanoengineering

open access: yesAdvanced Materials, EarlyView.
Nanoengineering enables precise control over biomaterial interactions with living systems by tuning surface energy, defects, porosity, and crystallinity. This review highlights how these nanoscale design parameters drive advances in regenerative medicine, drug delivery, bioprinting, biosensing, and bioimaging, while outlining key translational ...

Left ventricular diastolic dysfunction: identifying presence by left atrial function

open access: yesEcho Research and Practice, 2018
Objective: The left atrium (LA) is exposed to left ventricular pressure during diastole. Applying the 2016 American Society of Echocardiography left ventricular diastolic function (LVDF) guidelines, this study aims to investigate whether left atrial ...

Left ventricular systolic function in aortic stenosis [PDF]

open access: yes, 2017
In aortic valve stenosis, concentric hypertrophy develops which is characterized by a reduced end-diastolic radius-to-wall thickness ratio (r/h) with an essentially normal cavity shape.
