Cardiac Cohort Classification based on Morphologic and Hemodynamic Parameters extracted from 4D PC-MRI Data [PDF]

open access: yesarXiv, 2020
An accurate assessment of the cardiovascular system and prediction of cardiovascular diseases (CVDs) are crucial. Measured cardiac blood flow data provide insights about patient-specific hemodynamics, where many specialized techniques have been developed for the visual exploration of such data sets to better understand the influence of morphological ...

A Rapid and Computationally Inexpensive Method to Virtually Implant Current and Next-Generation Stents into Subject-Specific Computational Fluid Dynamics Models [PDF]

open access: yes, 2011
Computational modeling is often used to quantify hemodynamic alterations induced by stenting, but frequently uses simplified device or vascular representations.

Effect of various inspired oxygen concentrations on pulmonary and systemic hemodynamics and oxygenation during resuscitation in a transitioning preterm model. [PDF]

open access: yes, 2018
BackgroundThe Neonatal Resuscitation Program recommends initial resuscitation of preterm infants with low oxygen (O2) followed by titration to target preductal saturations (SpO2).

Bioengineering Platelets Presenting PD‐L1, Galectin‐9 and BTLA to Ameliorate Type 1 Diabetes

open access: yesAdvanced Science, EarlyView.
IFN‐γ‐primed platelets enriched with immunosuppressive ligands (PD‐L1, PD‐L2, BTLA, and Gal‐9) are shown to induce T cell exhaustion and apoptosis, preserving β‐cell function and preventing hyperglycemia progression in type 1 diabetes. IFN‐γ platelets also promote Treg expansion, macrophage polarization, and β‐cell proliferation, offering a promising ...

Automated expiratory ventilation assistance through a small endotracheal tube can improve venous return and cardiac output

open access: yesIntensive Care Medicine Experimental, 2019
Background Positive pressure ventilation can decrease venous return and cardiac output. It is not known if expiratory ventilation assistance (EVA) through a small endotracheal tube can improve venous return and cardiac output. Results In a porcine model,

Phosphodiesterase Type 5 Inhibitors, Sport and Doping [PDF]

open access: yes, 2017
Phosphodiesterase type 5 inhibitors (PDE5i) (e.g., sildenafil, tadalafil, vardenafil, and avanafil) are drugs commonly used to treat erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hyperplasia.

Analysis of the characteristics and management of perforated peptic ulcer from 2011 to 2022: A multicenter and retrospective descriptive study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The in‐hospital mortality rate for perforated peptic ulcer in this study was 5.0%, and conservative treatment was safely performed even in elderly patients. As the perforation diameter increased, the rate of gastrectomy tended to rise, and the rate of anastomotic leakage in those patients was high.

Hemodynamical Behavior Analysis of Anemic, Diabetic, and Healthy Blood Flow in the Carotid Artery [PDF]

open access: yes
The influence of blood rheology on hemodynamic parameters is investigated using Computational Fluid Dynamics on blood flow through the human carotid artery. We performed three-dimensional modeling and simulation to study blood flow through the carotid artery, which is divided into internal and exterior parts with a decreased radius.

Non-invasive evaluation of left ventricular afterload, part 2 : arterial pressure-flow and pressure-volume relations in humans [PDF]

open access: yes, 2010
The mechanical load imposed by the systemic circulation to the left ventricle is an important determinant of normal and abnormal cardiovascular function.

Impact of different anesthetic protocols during anesthesia for the establishment of a porcine model of acute kidney injury

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study details the adaptations required to establish a long‐term anesthetic protocol in pigs. Three protocols were evaluated, with some causing malignant hyperthermia, hypoglycemia, or hemoynamic instability. The final protocol proved effective for developing a porcine AKI model requiring adequate arterial pressure maintenance.
