Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation

open access: yesAdvanced Science, EarlyView.
Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...

Delivery of Human iPSC‐Derived RPE Cells in Healthy Minipig Retina Results in Interaction Between Photoreceptors and Transplanted Cells

open access: yesAdvanced Science, EarlyView.
Human induced pluripotent stem cell‐derived retinal pigment epithelial (hiPSC‐RPE) cells, cultured on a clinically relevant PDLLA scaffold, are transplanted into immunosuppressed minipigs. The study demonstrates the viability, integration, and preservation of RPE‐specific features without gliosis or neuroinflammation, supporting their potential as a ...

Ketamine Inhibits Lung Fluid Clearance through Reducing Alveolar Sodium Transport [PDF]

open access: yes, 2011
Ketamine is a broadly used anaesthetic for analgosedation. Accumulating clinical evidence shows that ketamine causes pulmonary edema with unknown mechanisms. We measured the effects of ketamine on alveolar fluid clearance in human lung lobes ex vivo. Our

The Cerebrospinal Fluid Secretion Rate Increases in Awake and Freely Moving Rats but Differs With Experimental Methodology

open access: yesAdvanced Science, EarlyView.
CSF dynamics are vital for neurological health. Yet accurate quantification of CSF rates is challenging. Using a novel technique in awake, freely moving rats, significantly higher secretion rates are found than in anesthetized rats. The findings highlight the importance of awake models and the adaptability of methods for studying CSF changes influenced

Characterization of the Community Structure of Large-Scale Functional Brain Networks During Ketamine-Medetomidine Anesthetic Induction [PDF]

open access: yesarXiv, 2016
One of the main goals of neuroscience is to understand how an organism's cognitive capacities or physiological states are potentially related to brain activities that involve the interaction of multiple brain structures and cortical areas. A key feature of functional brain networks is that they are modularly structured, and this modular architecture is

General anesthesia does not have persistent effects on attention in rodents [PDF]

open access: yes, 2019
Background: Studies in animals have shown that general anesthesia can cause persistent spatial memory impairment, but the influence of anesthetics on other cognitive functions is unclear.

Citrullination of NF‐κB p65 by PAD2 as a Novel Therapeutic Target for Modulating Macrophage Polarization in Acute Lung Injury

open access: yesAdvanced Science, EarlyView.
Peptidyl arginine deiminase 2 (PAD2) plays a key role in regulating macrophage function in Pseudomonas aeruginosa‐induced acute lung injury (ALI). Using single‐cell RNA sequencing and proteomics, a new PAD2‐catalyzed citrullination site on NF‐κB p65 (171 Arginine), modulating macrophage polarization is identified.

Characterization of Large-Scale Functional Brain Networks During Ketamine-Medetomidine Anesthetic Induction [PDF]

open access: yesarXiv, 2016
Several experiments provide evidence that specialized brain regions functionally interact and reveal that the brain processes and integrates information in a specific and structured manner. Networks can be applied to model brain functional activities, providing means to characterize and quantify this structured form of organization.

Development of Carbon‐11 Labeled Pyrimidine Derivatives as Novel Positron Emission Tomography (PET) Agents Enabling Brain Sigma‐1 Receptor Imaging

open access: yesAdvanced Science, EarlyView.
Novel carbon‐11 labeled pyrimidine derivatives are developed as PET imaging probes for visualizing sigma‐1 receptors in the brain. [11C]CNY‐01 demonstrates superior brain uptake and binding specificity in both rodents and non‐human primates. The study reveals decreased sigma‐1 receptor expression in Alzheimer's disease, offering a promising tool for ...

Enantioselective CE–MS analysis of ketamine metabolites in urine

open access: yesELECTROPHORESIS, Volume 44, Issue 1-2, Page 125-134, January 2023., 2023
Abstract The chiral drug ketamine has long‐lasting antidepressant effects with a fast onset and is also suitable to treat patients with therapy‐resistant depression. The metabolite hydroxynorketamine (HNK) plays an important role in the antidepressant mechanism of action.
