3D‐Printed Gastrointestinal Stents: In Vivo Evaluation in a Swine Small Bowel Perforation Model

Advanced Healthcare Materials, EarlyView.
Gastrointestinal fistulae and perforations can lead to severe complications including sepsis and patient death. In this work, the efficacy of 3D‐printed gastrointestinal stents composed of poly‐lactic‐acid (PLA) was evaluated in an in vivo swine model.

DNA Origami‐Templated Aptamer Chiral Structures Realize Cellular Enantioselectivity

Advanced Materials, EarlyView.
Aptamers displayed on tubular DNA origami nanostructures in defined chiral orientations (left‐ or right‐handed) exhibit enantioselective interactions with cell surface target proteins. While the right‐handed configuration supports only transient binding, the left handedness energetically favors protein dimerization and promotes subsequent ...

Single cell spatial profiling of FFPE splenic tissue from a humanized mouse model of HIV infection

Biomarker Research
Background Latency remains a major obstacle to finding a cure for HIV despite the availability of antiretroviral therapy. Due to virus dormancy, limited biomarkers are available to identify latent HIV-infected cells.

Excitability in semiconductor microring lasers: Experimental and theoretical pulse characterization

, 2010
We characterize the operation of semiconductor microring lasers in an excitable regime. Our experiments reveal a statistical distribution of the characteristics of noise-triggered optical pulses that is not observed in other excitable systems.

TREM2 Drives Neutrophil Extracellular Traps‐Induced Dendritic Cell Maturation and Contributes to Lupus Progression

Advanced Science, EarlyView.
TREM2 recognizes NETs‐derived MPO to promote DC maturation and antigen presentation, thereby exacerbating the autoimmune response in SLE. Mechanistically, TREM2 activation triggers the DAP12/SYK/ERK cascade and enhances NETs internalization by DCs, which in turn activates the cGAS/STING signaling pathway.

A method to estimate probability of disease and vaccine efficacy from clinical trial immunogenicity data

npj Vaccines, 2021
Vaccine efficacy is often assessed by counting disease cases in a clinical trial. A new quantitative framework proposed here (“PoDBAY,” Probability of Disease Bayesian Analysis), estimates vaccine efficacy (and confidence interval) using immune response ...

Magnetic Resonance Lithography with Nanometer Resolution

, 2015
We propose an approach for super-resolution optical lithography which is based on the inverse of magnetic resonance imaging (MRI). The technique uses atomic coherence in an ensemble of spin systems whose final state population can be optically detected ...
