Multimodal Imaging Reveals Cerebral Microcirculation Dynamics and Mechanisms in Mouse Central Nervous System After Intranasal Infection With Recombinant Pseudorabies Virus

open access: yesAdvanced Science, EarlyView.
Multi‐modality imaging strategy applied to PRV‐induced central nervous system infection enables dynamic visualization of cerebrovascular dysfunction, including hyperemia, hypoperfusion, and vascular remodeling. These changes are linked to microglial activation and impaired angiogenesis, providing mechanistic insight into PRV neuropathogenesis and ...

Vasodilation increases pulse pressure variation, mimicking hypovolemic status in rabbits

open access: yesClinics, 2010
OBJECTIVE: To test the hypothesis that pulse pressure respiratory variation (PPV) amplification, observed in hypovolemia, can also be observed during sodium nitroprusside (SNP)-induced vasodilation.

Interconversions between RNS Revealed by Transient Voltammetry with Porphyrin‐Modified Carbon Nanopipettes in Single Living Cells

open access: yesAdvanced Science, EarlyView.
By using porphyrin modified conductive nanopipettes, transient voltammetry can be directly applied to reveal the dynamic and complex electrochemical reactions between the reactive nitrogen species inside the single living cells. Abstract Reactive nitrogen species (RNS) play crucial roles in cellular signaling, but their quantification is very ...

Gel-forming antagonist provides a lasting effect on CGRP-induced vasodilation

open access: yesFrontiers in Pharmacology, 2022
Migraine affects ∼15% of the adult population, and the standard treatment includes the use of triptans, ergotamines, and analgesics. Recently, CGRP and its receptor, the CLR/RAMP1 receptor complex, have been targeted for migraine treatment due to their ...

Structural and Electronic Complexities of a Sulfur‐Bridged Di‐Iron Complex Composed of Mono‐ and Di‐Nitrosyl Units

open access: yesAdvanced Science, EarlyView.
Two NO‐containing iron units, biologically relevant as NO storage/release centers, connected by sulfur, display characteristics arising from multiple quantum levels in their extensively delocalized arrangement. Analysis in three charge levels finds the electron distribution almost substantially spread over all atoms of its composition: 2S, 2Fe, and 3NO.

The effect of crude ethanol extract and fractions of Hyptidendron canum (Pohl ex Benth.) Harley on the hepatopancreas of Oreochromis niloticus L

open access: yesBiological Research, 2009
Hyptidendron canum (Pohl ex Benth.) Harley is a native tree of the Brazilian Savannah. The fish Oreochromis niloticus L. was used as an experimental model to determine the bioactivity of the crude ethanol extract as well as ethyl acetate, hexanic and ...
