Secuencia perfusión arterial reversa. Reporte de caso

, 2018
Twin reversed arterial perfusion sequence is a complication of monochorionic twin pregnancies in which one twin that exhibits lethal anomalies, including acardia, is perfused by the other ‘pump’ twin via anastomoses between placental arteries.

Affinity‐Tuned Albumin Hitchhiking Extends the Bioorthogonal Capture Window in Pretargeting Radiotheranostics

Advanced Healthcare Materials, EarlyView.
Pharmacokinetic engineering of clickable radioligands was achieved via albumin hitchhiking approach within a pretargeted radiotheranostics delivery platform. This approach reduced rapid renal elimination, expanded bioorthogonal capture window, boosted tumor uptake by ∼3.5‐fold, and improved the tumor‐to‐liver ratio by ∼6‐fold.

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Thermally Modulated Metasurface Sensor for Dynamic and Time‐Resolved Isolation of Extracellular Vesicles

Advanced Materials, EarlyView.
A thermally adaptive plasmonic metasurface, functionalized with poly(N‐isopropylacrylamide) (PNIPAM) and anti‐CD63 antibodies, enables precise, on‐demand capture and release of extracellular vesicles (EVs). Delivering high recovery, improved purity, and intact vesicle structure, the platform offers a versatile, label‐free solution for real‐time EV ...

Dexime: A Selectively Enzyme‐Degradable Hydrogel for Protein Therapeutic Release

Advanced Materials, EarlyView.
A dextrin‐oxime hydrogel (dexime) is produced using ketone or aldehyde modified dextrin and tetra‐oxyamine modified poly(ethylene glycol). The rheological and mechanical properties of dexime are tunable. Dexime is injectable, cytocompatible, hydrolytically stable, and selectively degradable by α‐amylase.

Índice de perfusión periférica en la UCI neonatal: una respuesta a la monitorización no invasiva del recién nacido crítico

, 2017
La necesidad de abordar y monitorear a los pacientes de forma mínimamente invasiva pero de manera más exacta reduciendo así el número de complicaciones, es lo que permitió desarrollar a través de los años el concepto de índice de perfusión.
