A reliable regeneration system for faba bean has been difficult to establish and therefore, the genetic improvement of Vicia faba L. was delayed. The paper describes a method of somatic embryo induction in callus of V. faba. Two Egyptian faba bean cultivars 'Giza 2' and '24 Hyto' were used. Callus was induced from epicotyls and shoot tips cultured on MS or Gamborg medium supplemented with 3% su...

Background and Purpose N-acetylaspartate (NAA), the second most abundant amino acid derivative in the mammalian brain, is almost exclusive to neurons and their processes and, therefore, is regarded, as a marker for their health and density. Due to its unique specificity, NAA is the most frequently examined neuro-metabolite and its concentration has been reported to decline in all other central ...

Teucrium chamaedrys is regarded as an herbaceous perennial plant from Lamiaceae family that is used as medicinal plants and food from ancient times. Due to the recent developments in tissue culture techniques and extraction of secondary metabolites, this study aimed to investigate the explants of the Teucrium for callus induction and secondary metabolites. The interaction of Auxin hormones incl...

OBJECTIVE We previously demonstrated an inverse relationship between both dentate gyrus neurogenesis - a form of neuroplasticity - and expression of the antiapoptotic gene marker, BCL-2 and adult macaque body weight. We therefore explored whether a similar inverse correlation existed in humans between body mass index (BMI) and hippocampal N-acetyl-aspartate (NAA), a marker of neuronal integrity...

Biotechnological approaches provide an efficient and expeditious system for developing agronomic features of rice at the cellular molecular level compared to traditional breeding methods. The in-vitro regeneration method optimization recalcitrant indica genotypes is a critical step biotechnological further development as optimum concentrations Plant Growth Regulators (PGRs) vary from genotype g...

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 ...

BACKGROUND AND PURPOSE Diffusion tensor imaging (DTI) and MR spectroscopy are noninvasive, quantitative tools for the preoperative assessment of gliomas with which the quantitative parameter fractional anisotropy (FA) and the concentration of neurometabolites N-acetylaspartate (NAA), choline (Cho), creatine (Cr) of the brain can be determined. Measurements of FA and NAA reflect the integrity of...

Present study was carried out at research Farm of College Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh during 2019–20 to find effect PGRs micronutrients on granulation disorder citrus cv. Rangpur lime. Results observed significant micronutrient minimizing increasing the yield fruits. Among all treatments NAA @300 ppm + GA3 @15 ZnSO4 @0.5% CuSO4 (T6) sh...

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 (...

BACKGROUND N -acetylaspartate (NAA) level is a biomarker of functional integrity and vitality in neurons. In vivo multisection proton ((1)H)-magnetic resonance spectroscopy studies indicate that NAA level decreases in specific cortical brain areas of patients with amyotrophic lateral sclerosis (ALS). OBJECTIVE To study NAA level in serum samples as a possible biomarker of ALS. DESIGN Serum ...
