Lipid Nanoparticle‐Mediated CRISPR‐Cas13a Delivery for the Control of Bacterial Infection

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
New formulations of lipid nanoparticles (LNPs) that can deliver nucleic acids to Gram‐negative bacteria are proposed to combat bacterial infection. The delivery of nucleic acids by LNPs is aided by LNP‐helpers which weaken the bacterial outer membrane. LNPs encapsulating the Cas13a/gRNA expression vector achieve an antibacterial effect in both in vivo ...

Sunlight and vitamin D for bone health and prevention of autoimmune diseases, cancers, and cardiovascular disease.

open access: yesAmerican Journal of Clinical Nutrition, 2004
Most humans depend on sun exposure to satisfy their requirements for vitamin D. Solar ultraviolet B photons are absorbed by 7-dehydrocholesterol in the skin, leading to its transformation to previtamin D3, which is rapidly converted to vitamin D3. Season,

Morphometric‐Assisted Prediction of Developmental Toxicity Using Stem Cell‐Based Embryo Models in Microwells

open access: yesAdvanced Healthcare Materials, EarlyView.
This proof‐of‐concept study involves high‐throughput teratogenicity screening of compounds using XEn/EpiCs, a 3D stem cell‐based embryo model, within microwells. The term ‘morphotoxicity’ is introduced to complement traditional cytotoxicity assays through automated feature extraction and machine‐learning‐assisted classification of morphologies.

Organoid‐Like Neurovascular Spheroids Promote the Recovery of Hypoxic‐Ischemic Skin Flaps Through the Activation of Autophagy

open access: yesAdvanced Healthcare Materials, EarlyView.
Highly sprouting organoid‐like neurovascular spheroids (NVUs) are developed, featuring cell‐loaded poly‐3‐hydroxybutyrate 4‐hydroxybutyrate(P34HB) porous microsphere cores embedded within Gelatin Methacryloyl. NVUs formed complex vascular plexuses and secreted extracellular matrix in vitro, simulating autologous nerves and blood interaction.
