Choroidal neovascularization (CNV) is a hallmark of exudative age-related macular degeneration (exAMD) and a major cause of visual loss in AMD. Despite the widespread use of anti-VEGF therapy, serious adverse effects arise from repeated intravitreal injection of anti-VEGF antibodies, which warrant
N-Acetyl-L-histidine (NAH) and N-acetyl-L-aspartic acid (NAA) are major constituents of vertebrate brain and eye with distinct phylogenetic distributions. They are characterized by high tissue concentrations, high tissue/extracellular fluid gradients, and a continuous regulated efflux into the
Canavan disease (CD) is a human early-onset leukodystrophy, genetic in nature and resulting from an autosomally inherited recessive trait. CD is characterized by loss of the axon's myelin sheath, while leaving the axons intact, and spongiform degeneration, especially in white matter. It is an
The electroencephalographic and histopathological changes following intra-amygdaloid injection of excitatory amino acids were examined in rats. Limbic seizure status was induced after injection of kainic acid (KA), domoic acid (DA), quisqualic acid (QA), alpha-allo-kainic acid (ALLO-KA) and
Canavan disease (CD) is an autosomal recessive leukodystrophy caused by deficiency of aspartoacylase (ASPA). Deficiency of ASPA leads to elevation of N-acetyl-L-aspartic acid (NAA) in the brain and urine. To explore the feasibility of gene transfer to replace ASPA in CD, we generated a knockout
Canavan disease is a leukodystrophy caused by aspartoacylase (ASPA) deficiency. The lack of functional ASPA, an enzyme enriched in oligodendroglia that cleaves N-acetyl-l-aspartate (NAA) to acetate and l-aspartic acid, elevates brain NAA and causes "spongiform" vacuolation of superficial brain white
L-[3H]Glutamic acid binds reversibly to rat brain membranes with high affinity. Specific binding is linear with tissue concentration and has a pH optimum at neutrality. Saturation isotherms reveal anomolous kinetics of specific binding with an high affinity site with a KD of 11 nM and a lower
Neurotransmitters, small molecules widely distributed in the central nervous system are essential in transmitting electrical signals across neurons via chemical communication. Dysregulation of these chemical signaling molecules is linked to numerous neurological diseases including tauopathies. In
Osteoarthritis (OA), characterized by joint pain and cartilage degradation, is the most common form of joint disease worldwide but with no satisfactory therapy available. The ethanol extract of Agkistrodon acutus (EAA) has been widely used as a traditional Chinese medicine (TCM) for OBJECTIVE
To determine possible mechanisms that shape the negative electroretinograms (ERGs) in rats with photoreceptor degeneration induced by destruction of the retinal pigment epithelium.
METHODS
Sprague-Dawley rats (n = 48) were injected intravenously with 60 mg/kg of sodium iodate (NaIO(3)).
Canavan disease (CD) is a rare leukodystrophy characterized by diffuse spongiform white matter degeneration, dysmyelination and intramyelinic oedema with consequent impairment of psychomotor development and early death. The molecular cause of CD has been identified as being mutations of the gene
The amino acids L-glutamic and L-aspartic acids form the most widespread excitatory transmitter network in mammalian brain. The excitation produced by L-glutamic acid is important in the early development of the nervous system, synaptic plasticity and memory formation, seizures and neuronal
