It is unclear whether N-acetylaspartate (NAA) depletions documented in schizophrenia patients might be due to the disease progression or medications. Here we investigated longitudinal NAA changes in drug-naïve first-episode patients (FEP) who are relatively free from chronicity. Forty-two drug-naïve FEP and 38 controls were enrolled in this study to explore the effect of 8-week risperidone mono...

A rapid and efficient in vitro propagation protocol of Acorus calamus L. an important endangered medicinal plant has been developed. Naturally grown rhizome segments were used as explants for initial culture. Surface sterilized rhizome segments were cultured on Murashige and Skoog (MS) medium supplemented with various concentrations (0.5 mg l 3.0 mg l ) of cytokinins (BAP, Kn) and auxins (IAA, ...

BACKGROUND AND PURPOSE Despite the prominent peak of N-acetylaspartate (NAA) in proton MR spectroscopy ((1)H-MR spectroscopy) of the adult brain and its almost exclusive presence in neuronal cells, the total amount of NAA, regarded as their marker, is difficult to obtain due to signal contamination from the skull lipids. This article compares the performance of 2 methods that overcome this diff...

The aim of this study was to correlate magnetic resonance spectroscopy (MRS) measurements, including that for the N-acetyl aspartate (NAA)/creatine (Cr) ratio in the vermis (denoted V-NAA), right cerebellar hemisphere (R-NAA), and left (L-NAA) cerebellar hemisphere, with the clinical scale for the assessment and rating of ataxia (SARA) score for patients with spinocerebellar ataxia (SCA) types ...

PURPOSE To study the value of different parameters derived from single-voxel proton MR spectroscopy of the mesial temporal lobes in the lateralization of the epileptogenic zone in patients with temporal lobe epilepsy. METHODS We studied 12 healthy volunteers and 21 patients with temporal lobe epilepsy refractory to medical treatment, which was clearly lateralized with electroencephalography (...

Persimmon (Diospyros) is an economically important tree widely cultivated for woody grain production in China, and Diospyros lotus mainly used as the grafting stock of persimmon. However, breeding stress-resistant rootstocks D. using molecular means has yet to be achieved; particular, efficient blade-regeneration system not been perfected date. This study examined effects different plant-growth...

Bletilla striata (Thunb. ex A. Murray) Rchb. f., a species of perennial herb orchidaceae that has remarkable effects and high economic value, been intensively studied by many scholars. Although this seeds, the germination rate is exceptionally low, which leads to decreased germplasm resources increased market demand every year. To solve problem, study examined aseptic system direct seeding tech...

OBJECTIVE In the present study, we measured hippocampal N-acetyl-l-aspartate (NAA), choline (CHO) and creatine (CRE) values in patients with panic disorder and healthy control subjects using in vivo(1)H MRS. METHODS We scanned 20 patients meeting Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria for panic disorder and 20 matched healthy controls with a 1.5 Tesla GE Si...
