Drug repositioning of mesalamine via supramolecular nanoassembly for the treatment of drug-induced acute liver failure.

Acute liver failure (ALF) is characterized by rapid hepatic dysfunction, primarily caused by drug-induced hepatotoxicity. Due to the lack of satisfactory treatment options, ALF remains a fatal clinical disease, representing a grand challenge in global health. For the drug repositioning to ALF of mesalamine, which is clinically approved for the treatment of inflammatory bowel disease (IBD), we propose a supramolecular prodrug nanoassembly (SPNs).

Unexpectedly detected air bubbles in left ventricle during off-pump coronary artery bypass grafting: a case report.

Background: Unlike on-pump beating coronary artery bypass grafting, off-pump coronary artery bypass grafting (OPCAB) rarely causes intracardiac air embolisms. However, there have been several reports of air embolisms that occurred during OPCAB using a CO blower, which is commonly used to facilitate visualization of the anastomotic site. Herein, we describe a rare case of air bubbles detected only in the left ventricle during OPCAB.

Consensus Recommendations for Studies of Outflow Facility and Intraocular Pressure Regulation Using Ex Vivo Perfusion Approaches.

Intraocular pressure (IOP) elevation is the primary risk factor and currently the main treatable factor for progression of glaucomatous optic neuropathy. In addition to direct clinical and living animal in vivo studies, ex vivo perfusion of anterior segments and whole eyes is a key technique for studying conventional outflow function as it is responsible for IOP regulation. We present well-tested experimental details, protocols, considerations, advantages, and limitations of several ex vivo model systems for studying IOP regulation.

A streamlined algorithm for two-dimensional bandgaps and defect-state energy variations in InGaN-based micro-LEDs.

Bandgaps and defect-state energies are key electrical characteristics of semiconductor materials and devices, thereby necessitating nanoscale analysis with a heightened detection threshold. An example of such a device is an InGaN-based light-emitting diode (LED), which is used to create fine pixels in augmented-reality micro-LED glasses. This process requires an in-depth understanding of the spatial variations of the bandgap and its defect states in the implanted area, especially for small-sized pixelation requiring electroluminescence.

Time-Lapse Live-Cell Imaging Using Fluorescent Protein Sensors in Outflow Pathway Cells Under Fluid Flow Conditions.

The role of shear stress in regulating aqueous humor (AH) outflow and intraocular pressure (IOP) in the trabecular meshwork (TM) and Schlemm's canal (SC) of the eye is an emerging field. Shear stress has been shown to activate mechanosensitive ion channels in TM cells and induce nitric oxide production in SC cells, which can affect outflow resistance and lower IOP. Live-cell imaging using fluorescent protein sensors has provided real-time data to investigate the physiological relationship between fluid flow and shear stress in the outflow pathway cells.

Milk-derived extracellular vesicles enable gut-to-tumor oral delivery of tumor-activated doxorubicin prodrugs.

Oral chemotherapy has been emerging as a hopeful therapeutic regimen for the treatment of various cancers because of its high safety and convenience, lower costs, and high patient compliance. Despite the current advancements in nanoparticle-mediated drug delivery, numerous anticancer drugs susceptible to the hostile gastrointestinal (GI) environment exhibit poor permeability across the intestinal epithelium, rendering them ineffective in providing therapeutic benefits. In this paper, we focus on harnessing milk-derived extracellular vesicles (mEVs) for gut-to-tumor oral drug delivery by leveraging their high bioavailability.

Delirium in neonates and infants: a scoping review protocol.

Introduction: Delirium in neonates and infants is difficult to screen or assess because of their different developmental features and distinct delirium characteristics compared with those of older children. Some delirium management strategies, including assessment, pharmacological and non-pharmacological interventions, and prevention strategies, have been previously suggested for paediatric delirium. However, whether these strategies are effective for delirium in neonates and infants is unclear.

Coffee-Ring Mediated Thinning and Thickness-Dependent Dewetting Modes in Printed Polymer Droplets Coupled with Assembly of Quantum Dots for Anti-Counterfeiting.

Molecular transport processes in printed polymer droplets hold enormous importance for understanding wetting phenomena and designing systems in applications such as encoding, electronics, photonics, and sensing. This paper studies thickness-dependent dewetting modes that are activated by thermal annealing and driven by interfacial interactions within microscopically confined polymeric features. The printing of poly(2-vinylpyridine) is performed in a regime where coffee-ring effects lead to strong thinning of the central region of the deposit.

Clipless internal mammary artery harvesting for minimally invasive coronary artery bypass grafting using the shear-tip harmonic scalpel.

Background: The internal mammary artery (IMA) is the most commonly used graft in coronary artery bypass grafting (CABG) because of its superior long-term patency rate. However, its small diameter poses challenges in handling, and any vascular damage that may occur during harvesting can significantly affect surgical outcomes. The primary focus during IMA harvesting is to ensure safe and effective hemostasis without direct vascular injury, while ensuring secure and reliable ligation of the vascular branches.
