Permissive role for mGlu1 metabotropic glutamate receptors in excitotoxic retinal degeneration [PDF]
, 2017 Neuroprotection is an unmet need in eye disorders characterized by retinal ganglion cell (RGC) death, such as prematurity-induced retinal degeneration, glaucoma, and age-related macular degeneration.

A 3D In Vitro Model of the Human Hepatobiliary Junction
Advanced Science, EarlyView.A 3D human organoid platform reconstructs the hepatobiliary junction between primary adult hepatocytes and intrahepatic cholangiocytes. These adult hepatobiliary organoids (aHBOs) support directional bile transport from canaliculi to ductule‐like structures, enable quantitative imaging of junction dynamics, and reveal cell‐type‐specific vulnerabilities

The GluN3A Subunit Exerts a Neuroprotective Effect in Brain Ischemia and the Hypoxia Process
ASN Neuro, 2013 NMDARs ( N -methyl-d-aspartate receptors) mediate the predominantly excitatory neurotransmission in the CNS (central nervous system). Excessive release of glutamate and overactivation of NMDARs during brain ischemia and the hypoxia process are causally ...

PLoS ONE, 2012 Perinatal hypoxia-ischemia is a major cause of acute mortality in newborns and cognitive and motor impairments in children. Cerebral hypoxia-ischemia leads to excitotoxicity and necrotic and apoptotic cell death, in which mitochondria play a major role ...

Strain-Related Differences in Mouse Neonatal Hypoxia-Ischemia [PDF]
Developmental Neuroscience, 2018 Neonatal hypoxic-ischemic brain injury is commonly studied by means of the Vannucci procedure in mice or rats (unilateral common carotid artery occlusion followed by hypoxia). Previously, we modified the postnatal day 7 (P7) rat procedure for use in mice, and later demonstrated that genetic strain strongly influences the degree of brain injury in the ...

A Nanoparticle‐Integrated Complete Manufacturing Pipeline of Chemically Engineered Exosomes
Advanced Science, EarlyView.We report a novel manufacture technology of chemically engineered exosomes. The four steps of manufacturing, i.e., biogenesis, loading, isolation, and storage, are integrated by the use of a nanoparticle. The manufacture technology incorporates three innovative components, i.e., a new nano‐bio effect, a new composite nanoparticle, and a new isolation ...

Roles of nitric oxide in brain hypoxia-ischemia
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1999 A large body of evidence has appeared over the last 6 years suggesting that nitric oxide biosynthesis is a key factor in the pathophysiological response of the brain to hypoxia-ischemia. Whilst studies on the influence of nitric oxide in this phenomenon initially offered conflicting conclusions, the use of better biochemical tools, such as selective ...

Treatment with docosahexaenoic acid after hypoxia-ischemia improves forepaw placing in a rat model of perinatal hypoxia-ischemia [PDF]
American Journal of Obstetrics and Gynecology, 2010 Docosahexaenoic acid (DHA) is a dietary fatty acid with neuroprotective properties. We hypothesized that DHA treatment after hypoxia-ischemia would improve function and reduce brain volume loss in a perinatal rat model.Seven-day-old Wistar rat pups from 7 litters (n = 84) underwent right carotid ligation, followed by 8% O(2) for 90 minutes.
