Hydrophilic coating embolism (HCE) is a rare and underreported complication in neurointerventional practice that can lead to serious medical consequences. Two endovascular procedures were interrupted at our institution after a cloudy liquid content was observed inside the rotating hemostatic valves (RHV) during microcatheter withdrawal. In both cases, the same type of microcatheter (Prowler Select Plus) and RHV (Merit) were being used, and coating dislodgement was suspected.

Renal ischemia-reperfusion (IR) induces tissue hypoxia, resulting in disrupted energy metabolism and heightened oxidative stress. These factors contribute to tubular cell damage, which is a leading cause of acute kidney injury (AKI) and can progress to chronic kidney disease (CKD). The excessive generation of reactive oxygen species (ROS) plays a crucial role in the pathogenesis of AKI.

The detection of cysteine (Cys) and homocysteine (Hcy) in biological fluids has great significance for early diagnosis, including Alzheimer's and Parkinson's disease. The simultaneous determination of Cys and Hcy with a single probe is still a huge challenge. To enlarge the differences in space structure (line and ring) and energy (-721.

Herein, we investigated the changes in oral bacterial counts before and after surgery in infants who underwent cardiac surgery, as well as after oral care using an antiseptic mouthwash.
Materials And Methods: A total of 102 infants who underwent congenital heart disease surgery were enrolled in this study.
Evaluation of integrated polysaccharide, biopolymers and clay composite membranes for clarification process of citrus fruit (sweet lime) juice.

This study focuses on the development of an efficient membrane-based clarification process to enhance the performance of subsequent ultrafiltration and produce high-quality sweet lime juice. A range of casting solutions were prepared using a blend of pore-forming polymers, including polyvinylpyrrolidone (PVP), polyvinylidene fluoride (PVDF), and cellulose acetate (CA), dissolved in dimethylformamide (DMF) solvent through the phase inversion technique. To further enhance the membrane's performance, four biopolymers poly (lactic acid) (PLA), xanthan gum, chitosan, and gelatin were incorporated, with and without clay, to refine its structure, porosity, and surface properties.
