Laparoscopic Delivery of a MnO2‐P‐ICG Patch for Photodynamic Therapy and NK Cell‐Driven Immunotherapy in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
This study proposes a flexible MnO2‐P‐ICG nanofiber patch for laparoscopic treatment of liver tumors. The patch alleviates tumor hypoxia and induces photodynamic therapy (PDT) triggered immunogenic cell death, thereby activating the cGAS‐STING pathway and, in synergy with pachymaran, promoting NK cell–mediated innate immunity. This synergistic strategy

Ultrasound Activated Piezoelectric Dural Patches to Drive Endogenous Neural Stem Cell–Mediated Repair Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
This study presents a wireless, non‐invasive strategy for neural repair by developing a biodegradable piezoelectric dural patch that, under transcranial ultrasound, generates localized electrical fields to drive endogenous neural stem cells toward neuronal differentiation and functional integration.

Soft and Adhesive Cardiac Patch for Electrophysiological and Contraction Measurement

open access: yesAdvanced 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 ...

Bronchiolitis obliterans. [PDF]

open access: yes, 1989
Bronchiolitis obliterans in the adult patient is a relatively uncommon and vexing clinical entity. This confusion results because this pathologic finding occurs in a variety of diverse clinical settings.

Self‐Amplifying Redox Cycle Triggers Ferroptosis/Cuproptosis Synergy for Enhanced Bacterial Eradication

open access: yesAdvanced Science, EarlyView.
This study designs a targeted nanocomposite (ct@HMCF‐Dex) that responds to acidic infection microenvironments, releasing components which amplify oxidative stress. It disrupts bacterial redox balance, chelates metals to sustain lipid peroxidation, and synergistically induces cuproptosis/ferroptosis‐like death.

Clinical–Ultrasound Model to Predict the Clinical Course in Bronchiolitis

open access: yesChildren
Background: The aim of the present study was to develop a clinical–ultrasound model for early detection of hospital admission, pediatric intensive care unit (PICU) admission, and oxygen requirement in children diagnosed with acute bronchiolitis (AB ...

Nanoplastics and Neurodegeneration: A Roadmap From Mechanism to Causation

open access: yesAdvanced Science, EarlyView.
Nanoplastics are pervasive environmental contaminants with potentially profound implications for human health. Emerging evidence suggests a possible link between nanoplastic exposure and neurodegeneration, a key driver of ageing and dementia, yet causality remains unresolved.

Automated Adjustment of the Fraction of Inspired Oxygen (FiO2) and the Time Spent in Normoxemia in Preterm Infants

open access: yesActa Médica Portuguesa
Introduction: The challenge of maintaining normoxemia in preterm infants undergoing respiratory support and oxygen therapy has led to the development of closed-loop automatic control systems for FiO2.

The Role of Intensive Insulin Therapy on Superoxide Dismutase (Sod), Tumor Necrosis Factor-? (Tnf-?), and Interleukin-6 (Il-6) on Hyperglycemia in Critically Ill Patients [PDF]

open access: yes, 2009
Hyperglycemia and insulin resistance are common in critically ill patientsin the ICU, although they have not previously had diabetes. It has been reportedthat pronounced hyperglycemia may lead to complications in such patients, andcause the reactive ...

Synchronization‐Dissipation in the Cardiorespiratory System

open access: yesAdvanced 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.
