Urine‐Stable Aptamer‐Conjugated Gold Nanorods for the Early Detection of High‐Grade Bladder Cancer Residual Disease

open access: yesAdvanced Healthcare Materials, EarlyView.
Aptamer (A) conjugated gold nanorods (B) for the recognition of bladder cancer cells expressing the integrin α5β1 (C) and the visualization of the targeted GNRs@Chit‐Apt‐Itg by photoacoustic imaging at the surface of the orthotopic bladder cancer in the preclinical model (D).

Testing Biased Randomization Assumptions and Quantifying Imperfect Matching and Residual Confounding in Matched Observational Studies [PDF]

open access: yesarXiv, 2021
One central goal of design of observational studies is to embed non-experimental data into an approximate randomized controlled trial using statistical matching. Despite empirical researchers' best intention and effort to create high-quality matched samples, residual imbalance due to observed covariates not being well matched often persists.

Living Microalgae‐Based Magnetic Microrobots for Calcium Overload and Photodynamic Synergetic Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
A magnetic microrobot fabricated by Spirulina platensis is proposed to accumulate in tumor regions and generate in situ high calcium concentration and sufficient oxygen. These characteristics of the microrobot present a strategy for triggering calcium overload therapy and chlorophyll‐mediated photodynamic therapy, and such combination resulted in a ...

Toward Robotically Automated Femoral Vascular Access [PDF]

open access: yesarXiv, 2021
Advanced resuscitative technologies, such as Extra Corporeal Membrane Oxygenation (ECMO) cannulation or Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), are technically difficult even for skilled medical personnel. This paper describes the core technologies that comprise a teleoperated system capable of granting femoral vascular ...

Percutaneous closure of PFO in patients with reduced oxygen saturation at rest and during exercise : short- and long-term results [PDF]

open access: yes, 2020
Background. A patent foramen ovale (PFO) is a rare cause of hypoxemia and clinical symptoms of dyspnea. Due to a right-to-left shunt, desaturated blood enters the systemic circulation in a subset of patients resulting in dyspnea and a subsequent ...

An In Situ Curing, Shear‐Responsive Biomaterial Designed for Durable Embolization of Microvasculature

open access: yesAdvanced Healthcare Materials, EarlyView.
NeoCast is a next‐generation, solvent‐free, non‐adhesive liquid embolic designed for indications where deep occlusion is desired (e.g., tumors and chronic subdural hematoma). This novel agent offers ideal embolic properties: injectability, controllability, excellent visibility, and biocompatibility.

Variable Selection for Causal Inference via Outcome-Adaptive Random Forest [PDF]

open access: yesarXiv, 2021
Estimating a causal effect from observational data can be biased if we do not control for self-selection. This selection is based on confounding variables that affect the treatment assignment and the outcome. Propensity score methods aim to correct for confounding. However, not all covariates are confounders.

Hollow‐Structured Nanorobot with Excellent Magnetic Propulsion for Catalytic Pollutant Degradation, Anti‐Bacterial and Biofilm Removal

open access: yesAdvanced Healthcare Materials, EarlyView.
A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...
