Mechanically Robust Biodegradable Stents With Theragenerative Vascular Responses via Combined 3D Printing and Janus Nanoengineering

Advanced Science, EarlyView.
This work introduces a theragenerative 3D‐printed biodegradable stent with Janus nanoarchitecture for spatially controlled vascular healing. A luminal tantalum ion–implanted surface accelerates endothelialization and hemocompatibility, while an abluminal sirolimus/poly‐L‐lactic acid–tantalum layer provides sustained drug release and suppresses smooth ...

Inhalation Anesthesia Increases V/Q Regional Heterogeneity during Spontaneous Breathing in Healthy Subjects

, 2010
Background The underlying mechanism for the increased alveolar-arterial oxygen tension difference resulting from almost all forms of general anesthesia is unknown. We hypothesized that inhalation anesthesia influences

Bioadhesive Hydrogel With Polyphenol‐Armored Nanogene Rejuvenates Chondrocyte Senescence for Aged Osteoarthritis Therapy

Advanced Science, EarlyView.
An adhesive hydrogel depot with polyphenol‐armored nanogenes is developed for treating aged osteoarthritis. This system maintains miR‐140 bioactivity, prolongs its intra‐articular retention, and enhances transfection into chondrocytes, leading to the downregulation of senescence‐associated pathways.

CD11b+CD43hiLy6Clo splenocyte‐derived macrophages exacerbate liver fibrosis via spleen–liver axis

Hepatology, EarlyView., 2022
A population of splenic monocytes migrate into the liver and shift to macrophages, which account for the exacerbation of liver fibrosis. Abstract Background and Aims Monocyte‐derived macrophages (MoMFs), a dominant population of hepatic macrophages under inflammation, play a crucial role in liver fibrosis progression.

Combining interscalene brachial plexus block with intravenous-inhalation combined anesthesia for upper extremity fractures surgery: A randomized controlled trial

, 2014
Background: A parallel-group randomized controlled trial (RCT) was conducted to evaluate the effect of combining the interscalene brachial plexus block (IBPB) with Intravenous–inhalation combined anesthesia to isolated Intravenous–inhalation anesthesia ...

Anesthesia in the surgery of strabismus: role of anesthetic agents in the ocular deviation and surgical outcome [PDF]

, 2015
Purpose: To determine whether the changes in the ocular alignment following general anesthesia, maintained with two different inhalational anesthetic agents, sevoflurane and desflurane, can be used as a predictor for surgical outcomes in children with ...

Soft and Adhesive Cardiac Patch for Electrophysiological and Contraction Measurement

Advanced Science, EarlyView.
This study developed an epicardial electronic patch with a modulus similar to that of the heart (approximately 65kPa), which can collect stable electrocardiogram signals and myocardial contractility on the surface of a dynamically beating heart. This is attributed to the hydrogen bond interaction formed between the amino and catechol groups in the ...

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.
