Vascularized and Perfusable Human Heart‐on‐a‐Chip Model Recapitulates Aspects of Myocardial Ischemia and Enables Analysis of Nanomedicine Delivery

open access: yesAdvanced Materials, EarlyView.
This novel 3D human ischemic heart‐on‐a‐chip, with perfusable vasculature directly interfaced with myocardial tissue, replicates key aspects of ischemic heart injury. It also demonstrates the targeted delivery and therapeutic efficacy of cardiac homing peptide‐conjugated liposomes, validating the platform for drug and nanomedicine screening in ...

Composition and conservation of the mRNA-degrading machinery in bacteria

open access: yesJournal of Biomedical Science, 2011
RNA synthesis and decay counteract each other and therefore inversely regulate gene expression in pro- and eukaryotic cells by controlling the steady-state level of individual transcripts.

Plaque‐Targeted Delivery of Fluoride‐Free MXene Nanozyme for Alleviating Atherosclerosis via Sonocatalytic Therapy

open access: yesAdvanced Materials, EarlyView.
This work has developed a dual enzyme‐mimicking and ultrasound‐responsive Nb2C‐Pt@HA‐PEG nanozyme. ROS‐eliminating and anti­inflammatory capability of Nb2C‐Pt@HA‐PEG under US irradiation are demonstrated on macrophages and endothelial cells in vitro. Nb2C‐Pt@HA‐PEG‐mediated sonocatalytic therapy exerts an outstanding anti‐atherosclerosis efficacy by ...

Nonsense-Mediated RNA Decay Influences Human Embryonic Stem Cell Fate

open access: yesStem Cell Reports, 2016
Summary: Nonsense-mediated RNA decay (NMD) is a highly conserved pathway that selectively degrades specific subsets of RNA transcripts. Here, we provide evidence that NMD regulates early human developmental cell fate. We found that NMD factors tend to be

Light‐Harvesting Nanomaterials Based on Dyes for Energy Transfer and Amplified Biosensing

open access: yesAdvanced Materials, EarlyView.
Light harvesting (LH) in plants inspires researchers to develop artificial LH nanomaterials. Here, LH nanomaterials based on organic dyes are reviewed, considering fundamental challenges on aggregation‐caused quenching, excitation energy transfer, and exciton migration length.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Changes in mRNA abundance drive shuttling of RNA binding proteins, linking cytoplasmic RNA degradation to transcription

open access: yeseLife, 2018
Alterations in global mRNA decay broadly impact multiple stages of gene expression, although signals that connect these processes are incompletely defined.

Virus Replication as a Phenotypic Version of Polynucleotide Evolution

open access: yes, 2013
In this paper we revisit and adapt to viral evolution an approach based on the theory of branching process advanced by Demetrius, Schuster and Sigmund ("Polynucleotide evolution and branching processes", Bull. Math. Biol.

Designing the Next Generation of Biomaterials through Nanoengineering

open access: yesAdvanced Materials, EarlyView.
Nanoengineering enables precise control over biomaterial interactions with living systems by tuning surface energy, defects, porosity, and crystallinity. This review highlights how these nanoscale design parameters drive advances in regenerative medicine, drug delivery, bioprinting, biosensing, and bioimaging, while outlining key translational ...

Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

open access: yesAdvanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...
