A Vascularized Microphysiological System Reproducing Endochondral Ossification in Vitro to Study Ewing Sarcoma Proliferation and Migration

open access: yesAdvanced Functional Materials, EarlyView.
A biofabricated 3D in vitro model recapitulating endochondral ossification (ECO) is described, mimicking the steps from condensation to chondrogenesis and hypertrophy, culminating with vascularization of the hypertrophic construct. As a model proof of concept application, Ewing Sarcoma cells are seeded in the model, showing modifications in their ...

A rhodanine agent active against non-replicating intracellular Mycobacterium avium subspecies paratuberculosis. [PDF]

open access: yes, 2009
BACKGROUND: Antibiotic therapy targeting chronic mycobacterial disease is often ineffective due to problems with the emergence of drug resistance and non-replicating persistent intracellular antibiotic resistant phenotypes.

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Reconstructing phylogeny from RNA secondary structure via simulated evolution

open access: yes, 2002
DNA sequences of genes encoding functional RNA molecules (e.g., ribosomal RNAs) are commonly used in phylogenetics (i.e. to infer evolutionary history).

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Effect of restricted mobility on RNA content and nucleotide composition and on protein content in motoneurons of spinal cord anterior horns [PDF]

open access: yes
An investigation into the effect of hypokinesia on the ribonucleic acid (RNA) content, the nucleotide composition, and dynamics of protein content in the motoneuron of the rat spinal cord anterior horns is described.

Nanocarrier‐Based Targeting of Pattern Recognition Receptors as an Innovative Strategy for Enhancing Sepsis Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
This review highlights recent progress in nanocarriers targeting pattern recognition receptors (PRRs), including Toll‐like and NOD‐like receptors, for enhancing the treatment of bacterial sepsis and related complications. These nanomedicines deliver antibiotics and anti‐inflammatory agents while modulating immune responses.
