A novel biomimetic liposome drug delivery system mediated by macrophage targeting for precision treatment of encephalitis

BMEMat, EarlyView.
An advanced macrophage‐mediated biomimetic liposome (AC‐LP@RAW) that can penetrate the BBB and precisely target inflammatory sites in the deep brain was established in this study based on the unique immune homing property of macrophages, and showed a significantly improved delivery of curcumin to the brain.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

β‐Ketonitrile‐Modified Prodan Derivatives as Large‐Stokes‐Shift Solvatochromic Fluorophores With Enhanced Brightness and Ratiometric Thermometric Response

Chemistry – A European Journal, EarlyView.
We report a systematic study of β‐ketonitrile–modified Prodan‐type solvatochromic fluorophores. The β‐ketonitrile substitution induces marked bathochromic shifts in absorption and emission and significantly enhances fluorescence quantum yields in nonpolar solvents.

Repairing Qinling Giant Panda Skin Wounds Using Adipose Mesenchymal Stem Cell-Derived Extracellular Vesicles

Animals
The Qinling giant panda has a high susceptibility to skin damage, which affects its survival. Although their healing efficacy in panda injuries remains unexplored, extracellular vesicles from adipose-derived mesenchymal stem cells (ADMSC-EVs) have shown ...

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

Cytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Food Contamination and Safety in Nigeria: A Systematic Synthesis of Heavy Metals, Microbial Pathogens, and Health Risk Metrics

Food Safety and Health, EarlyView.
This is an infographic driver of food contaminants and health effects. ABSTRACT Food safety remains a critical challenge in Nigeria due to rapid urbanization and weak regulatory enforcement. This systematic review synthesizes empirical evidence from 2015 to 2025 to characterize food contaminant profiles and associated human health risks in Nigeria ...

On-Chip Inverted Emulsion Method for Fast Giant Vesicle Production, Handling, and Analysis

Micromachines, 2020
Liposomes and giant unilamellar vesicles (GUVs) in particular are excellent compartments for constructing artificial cells. Traditionally, their use requires bench-top vesicle growth, followed by experimentation under a microscope.

Intercellular communication between artificial cells by allosteric amplification of a molecular signal

Nature Communications, 2020
The principles of intercellular communication in multicellular organisms can be explored using artificial cells. Here, the authors report on giant vesicles which can recognize diffused chemical signals and amplify the signal by synthetic enzymatic ...

Giant vesicles

, 2009
In the present study a novel approach to characterize lipid domains, which may provide binding sites for peripheral or integral membrane proteins, is demonstrated. In particular, analysis of fluorescence lifetimes of NBD-labeled lipid analogues was used to study lipid domains in Giant unilamellar vesicles (GUV) and – based on the GUV results – in the ...
