Paraquat disrupts the blood–brain barrier by increasing IL-6 expression and oxidative stress through the activation of PI3K/AKT signaling pathway

Open Medicine
Paraquat (PQ) is a frequently used herbicide with neurotoxic effects after acute or chronic exposure. Although in vitro evidence supports the PQ toxicity to dopamine cells, its in vivo effects (especially the chronic exposure) remain ambiguous.

Microglia Regulate Blood–Brain Barrier Integrity via MiR‐126a‐5p/MMP9 Axis during Inflammatory Demyelination

Advanced Science, 2022
Blood–brain barrier (BBB) impairment is an early prevalent feature of multiple sclerosis (MS), and remains vital for MS progression. Microglial activation precedes BBB disruption and cellular infiltrates in the brain of MS patients.

Three‐Dimensional Biomimetic Aerogel Conduits with Electro‐Ionic‐Immune Coupling Reverse the Pathological Cascade of Spinal Cord Injury

Advanced Functional Materials, EarlyView.
A biomimetic aerogel conduit was engineered from a nanofiber of gelatin/poly(l‐lactic acid) doped with polypyrrole nanoparticles, integrated with tannic acid and Mg2+. This “electro‐ionic‐immune” strategy mimicked spinal cord properties, reduced calcium overload, inflammation, oxidative damage, promoted neural stem cell differentiation, suppressed ...

On the degeneration of étale $\Bbb Z/p\Bbb Z$ and $\Bbb Z/p^2\Bbb Z$-torsors in equal characteristic $p>0$

Hiroshima Mathematical Journal, 2007
Let $R$ be a complete discrete valuation ring of equal characteristic $p>0$. In this paper we investigate finite and flat morphisms $f:Y\to X$ between formal $R$-schemes which have the structure of an etale $\Bbb Z/p^n\Bbb Z$-torsor above the generic fiber of $X$, for $n=1,2$, with some extra geometric conditions on $X$ and $Y$.

Functional Blood‐Brain Barrier Crossing by Biomimetic M13 Phage Vectors for Targeted Neuronal Delivery

Advanced Healthcare Materials, EarlyView.
This study investigates the M13 bacteriophage as a biomimetic nanovector capable of crossing in vitro models of the blood–brain barrier. By exploiting peculiar transcellular pathways, M13 avoids lysosomal degradation and preserves its structural integrity and functionality.

“Build back better” approach to disaster recovery: Research trends since 2006

Progress in Disaster Science, 2019
The “build back better” (BBB) approach to disaster recovery was first introduced in 2006 by the United Nations Secretary-General's Special Envoy for Tsunami Recovery, former US President William Clinton.

Recent Advances in Ferrite‐Based Materials for Biomedical Applications: A Comprehensive Review

Advanced Materials, EarlyView.
Ferrite nanoplatforms are presented as tunable biomedical materials in which synthesis control, cation engineering, defect/morphology regulation, and surface functionalization govern structure–property–bioactivity relationships. These design strategies enable multifunctional applications including MRI contrast, magnetic hyperthermia, targeted drug ...

OBJECTIVE METHODS FOR DETERMINE THE SEVERITY AND PROGNOSIS OF PERINATAL HYPOXIC-ISCHEMIC CNS

Акушерство, гинекология и репродукция, 2016
Perinatal hypoxic-ischemic damage of the CNS is a major cause of mortality and neonatal incapacitating. The severity and prognosis is not always possible to accurately determine by clinical and tools methods of examination.
