Abstract Background The thalamus is crucial in the development of idiopathic generalized epilepsy (IGE), which could lead to cognitive dysfunctions, according data from neuropsychology and advanced neuroimaging investigations. This research aimed measure metabolic changes assess if be contributed impairment IGE patients. Thirty patients thirty healthy volunteers with matched ages, genders, educ...

A method is described that allows the in vivo differentiation of N-acetyl aspartate (NAA) from N-acetyl aspartyl glutamate (NAAG) by in vivo MR spectroscopy (MRS) at 3 Tesla (3T). The method, which is based on MEGA-point-resolved spectroscopy (PRESS) editing, selectively targets the aspartyl spin system of one species while deliberately removing the other species from the spectrum. This allows ...

BACKGROUND Previous neuropathological and neuroimaging studies have documented neuronal loss in the hippocampal region in schizophrenia. N-acetylaspartate (NAA) is a neuronal/axonal marker that may be utilized to assess neuronal loss or dysfunction by proton magnetic resonance spectroscopy (1H MRS). This study measured NAA, choline, and creatine in the hippocampal region of patients with schizo...

Strawberry is a valuable, nutritious, and economically important fruit all over the world including Bangladesh. Therefore, there is a demand to develop a suitable variety of strawberry. For this purpose, leaf explants from in vitro grown strawberry plantlets were cultured onto MS medium supplemented with different concentrations and combinations of 2,4-D, NAA and BA for callus induction. The mo...

Background and Purpose--Magnetic resonance spectroscopy (MRS) in ischemic stroke has shown a correlation between N-acetylaspartate (NAA) loss from the infarcted region and disability. We tested the hypothesis that NAA loss in the descending motor pathways, measured at the level of the posterior limb of the internal capsule, would determine motor deficit after a cortical, subcortical, or striato...

Individuals with posttraumatic stress disorder (PTSD) had experiences of enormous psychological stress that can result in neurocognitive and neurochemical changes. To date, the causal relationship between them remains unclear. The present study is to investigate the association between neurocognitive characteristics and neural metabolite concentrations in North Korean refugees with PTSD. A tota...

BACKGROUND AND PURPOSE Proton MR spectroscopy has revealed impaired neuronal integrity in the motor cortex of patients with amyotrophic lateral sclerosis (ALS). We hypothesized that the N-acetylaspartate (NAA)-creatine (Cr) ratios in the motor cortex and adjacent brain could reflect the therapeutic effectiveness of gabapentin (GBP) treatment in ALS. METHODS Eight patients with ALS underwent M...

Focal brain damage occurring early in development can have widespread repercussions throughout the developing brain. In living adult rhesus monkeys, we studied the long-term effects of early mesial temporo-limbic (MTL) lesions on prefrontal cortex (PFC) neurons using proton magnetic resonance spectroscopic imaging (1H-MRSI), an in vivo neurochemical assay technique for measuring signals from me...

The study compared the effects of 1.0 × MS medium containing various concentrations of α-naphthaleneacetic acid (NAA), indole-3-acetic acid (IAA), and indole-3-butyric acid (IBA), alone or in combination with gibberellic acid (GA3) in micropropagation of three potato (Solanum tuberosum L.) cultivars Pasinler, Granola, and Caspar using binodal stem cuttings. The results testified improved regene...
