HIV-1 RNA detection in the amniotic fluid of HIV-infected pregnant women

Memorias do Instituto Oswaldo Cruz, 2010
This study is aimed at evaluating the potential to detect human immunodeficiency virus (HIV) in amniotic fluid (AF) collected at delivery from 40 HIV-positive pregnant women. Thirty patients had a plasma viral load (VL) below 1,000 copies/mL at delivery.

Aptamer‐Directed Porous DNA Nanocomposite Hydrogel for Active Pulp Preservation: Immunomodulation, Stem Cell Recruitment and Reparative Dentinogenesis

Advanced Science, EarlyView.
This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.

Thermostable Bioluminescent Intercalating Dyes for Real‐Time, Integrated Nucleic Acid Amplification and Detection

Angewandte Chemie, EarlyView.
We present a bioluminescent diagnostic platform that integrates DNA amplification and detection in a single step. The engineering of thermostable luciferase‐intercalating dye conjugates and controlled release of caged luciferin substrates enable real‐time, detection of attomolar concentrations of viral DNA within 30 min.

Light‐Switched Mesenchymal Stem Cells for In Situ Exosome Amplification in Craniofacial Bone Defect Reconstruction

Advanced Science, EarlyView.
Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs

Eco‐Geography Reverses Dominant AMR Reservoirs in Klebsiella pneumoniae: Integron‐Rich Mobilomes and Cross‐Niche Connectivity

Advanced Science, EarlyView.
Dominant antimicrobial resistance reservoirs in Klebsiella pneumoniae vary across eco‐geographic settings rather than following a universal pattern. Integrated One Health and global genomic analyses show that lineage structure, integron load, and cross‐niche connectivity shape whether AMR burden accumulates primarily in human or nonhuman compartments ...

A Periosteum‐Inspired Janus Piezoelectric Scaffold Using Bioenergetic‐Driven H‐Type Vascularization for Diabetic Bone Regeneration

Advanced Science, EarlyView.
A periosteum‐inspired Janus piezoelectric scaffold converts micromechanical forces into electrical signals and synergizes with controlled resveratrol release. This dual action reprograms endothelial metabolism, drives H‑type vessel formation, and restores bone–vessel coupling in diabetic bone defects.
