Right ventricular outflow tract velocity time integral-to-pulmonary artery systolic pressure ratio: a non-invasive metric of pulmonary arterial compliance differs across the spectrum of pulmonary hypertension. [PDF]

open access: yes, 2019
Pulmonary arterial compliance (PAC), invasively assessed by the ratio of stroke volume to pulmonary arterial (PA) pulse pressure, is a sensitive marker of right ventricular (RV)-PA coupling that differs across the spectrum of pulmonary hypertension (PH ...

Human Brain Vasculature‐on‐a‐Chip Model Constructed With Microvessels Isolated From Cryopreserved Postmortem Human Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
This manuscript describes the cultivation of viable microvessels from cryopreserved human brain tissue. When embedded in hydrogels and cultured in microfluidic devices, these microvessels exhibit complex architectures reminiscent of arterioles and capillaries, can be perfused, and display intact barrier function. Collectively, these results demonstrate

Lifting the fog in intermediate-risk (submassive) PE: full dose, low dose, or no thrombolysis? [version 1; peer review: 2 approved]

open access: yesF1000Research, 2019
Acute pulmonary embolism (PE) is a disease frequently encountered in clinical practice. While the management of haemodynamically stable, low risk patients with acute PE is well established, managing intermediate disease often presents a therapeutic ...

A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

open access: yesAdvanced Healthcare Materials, EarlyView.
Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.

Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

open access: yesAdvanced Healthcare Materials, EarlyView.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.

Is pulmonary vascular remodeling an intermediate link between hyperglycemia and adverse outcomes in patients with idiopathic pulmonary arterial hypertension? Insights from a multi-center cohort study

open access: yesCardiovascular Diabetology
Background Hyperglycemia upon admission is associated with poor prognosis of many cardiovascular diseases. However, the relationship of stress hyperglycemia ratio (SHR), admission blood glucose (ABG), and hemoglobin A1c (HbA1c) with pulmonary ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Stiff to Soft: A Protein‐Based Buffer Layer for Improving the Long‐Term Performance of Microneedle Sensors

open access: yesAdvanced Materials, EarlyView.
To enhance stability and long‐term biocompatibility of wearable microneedle sensors, a crosslinking‐recombination bovine serum albumin material is used as a buffer layer coated on microneedle sensors. This coating layer possesses a unique stiff‐to‐soft transition function balancing the mechanical stiffness desired for puncturing and soft required for ...
