Elderly Liver Grafts are More Susceptible to Ischemia‐Reperfusion After Prolonged Cold Ischemia than Grafts from Young Donors—An Ex Vivo Liver Machine Perfusion Analysis in Sprague Dawley Rats

open access: yesAdvanced Therapeutics, EarlyView.
This study investigates how donor age and cold ischemia time influence liver perfusion parameters and injury markers. Older livers are more susceptible to longer ischemia times displaying more tissue damage, and higher expression of oxidative stress and apoptosis‐related proteins than livers with shorter ischemia times.

Nitric Oxide Synthase: Non-Canonical Expression Patterns

open access: yesFrontiers in Immunology, 2014
Science can move ahead by questioning established or canonical views and, so it may be with the enzymes, nitric oxide synthases (NOS). Nitric oxide (NO) is generated by NOS isoforms that are often described by their tissue-specific expression patterns ...

VDLIN: A Deep Learning‐Based Platform for Methylcobalamin‐Inspired Immunomodulatory Compound Screening

open access: yesAdvanced Science, EarlyView.
Using the convolutional neural network model VDLIN, Co7 is identified as a promising therapeutic candidate. Co7 demonstrates distinct advantages over MCB by effectively balancing anti‐inflammatory and immune‐stimulatory functions, making it a potential novel approach for immune modulation.

Subventricular Zone‐on‐a‐Chip: A Model to Study Neurogenesis Disruption in Neonatal Intraventricular Hemorrhage

open access: yesAdvanced Science, EarlyView.
A human subventricular zone‐on‐a‐chip is developed to model intraventricular hemorrhage (IVH) in preterm infants. This platform enables the study of inflammation‐driven neurogenic disruption. Exposure to hemorrhagic cerebrospinal fluid and red blood cell lysate activated inflammatory pathways, with IL1B emerging as a key mediator.

Lipopolysaccharide induces nitric oxide synthase expression and platelet-activating factor increases nitric oxide production in human fetal membranes in culture

open access: yesReproductive Biology and Endocrinology, 2004
Background Platelet-activating factor and nitric oxide may be involved in the initiation of human labour as inflammatory mediators. The aim of this study was to test whether platelet-activating factor and lipopolysaccharide were able to induce nitric ...

Blocked dihydropteridines as nitric oxide synthase activators [PDF]

open access: yes, 2010
It has been shown that 6-acetyl-7,7-dimethyl-5,6,7,8-tetrahydropteridin-4(3H)-one can act as a competent cofactor for the production of nitric oxide by neuronal nitric oxide synthase (nNOS).

eNOS transfection of adipose-derived stem cells yields bioactive nitric oxide production and improved results in vascular tissue engineering. [PDF]

open access: yes, 2015
This study evaluates the durability of a novel tissue engineered blood vessel (TEBV) created by seeding a natural vascular tissue scaffold (decellularized human saphenous vein allograft) with autologous adipose-derived stem cells (ASC) differentiated ...

Circular RNA PTPN4 Contributes to Blood‐Brain Barrier Disruption during Early Epileptogenesis

open access: yesAdvanced Science, EarlyView.
Epileptic condition induces CircPTPN4 upregulation, which promotes ECE‐1 expression through competitive sequestration of miR‐145a‐5p. The elevated ECE‐1 catalyzes the ET‐1 production, leading to p38/MAPK pathway activation and subsequent downregulation of tight junction protein expression. This cascade results in increased BBB permeability and enhanced

Investigations into potential extrasynaptic communication between the dopaminergic and nitrergic systems

open access: yesFrontiers in Physiology, 2012
Nitric oxide is unconstrained by cell membranes and can therefore act along a broad distance as a volume transmitter. Spillover of nitric oxide between neurons may have a major impact on central nervous system diseases and particularly on ...

Pathophysiological Role of Caveolae in Hypertension [PDF]

open access: yes, 2019
Caveolae, flask-shaped cholesterol-, and glycosphingolipid-rich membrane microdomains, contain caveolin 1, 2, 3 and several structural proteins, in particular Cavin 1-4, EHD2, pacsin2, and dynamin 2.
