BACKGROUND Clinical assessment is insensitive to the degree of cerebral involvement in amyotrophic lateral sclerosis (ALS). Regional brain concentrations N-acetylaspartylglutamate (NAA) plus myo-inositol (Ins), as measured by magnetic resonance spectroscopy, are respectively decreased and increased, suggesting that these compounds may provide a biomarker of the degree of cerebral involvement in...
گیاه صبر زرد (aloe vera l.)، گیاهی پایا از خانواده liliaceae با خواص حیرت انگیز می باشد که امروزه در صنایع مختلف دارویی، آرایشی و بهداشتی و همین طور غذایی کاربردهای فراوان دارد. تکثیر بذری این گیاه به دلیل وجود نر عقیمی بالا از کارایی اندکی برخوردار است. از اینرو، توجه محققان به تکثیر غیر جنسی این گیاه برای پاسخ به نیاز صنایع وابسته به آلوئه معطوف گردیده است. در این راستا روش کشت بافت گیاهی برا...
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...
The neuronal dipeptide N-acetylaspartylglutamate (NAAG) is thought to be synthesized enzymatically from N-acetylaspartate (NAA) and glutamate. We used radiolabeled precursors to examine NAA and NAAG biosynthesis in SH-SY5Y human neuroblastoma cells stimulated with activators of protein kinase A (dbcAMP; N6,2'-O-dibutyryl cAMP) and protein kinase C (PMA; phorbol-12-myristate-13-acetate). Differe...
In this study, articles in English and Chinese were selected from available electronic databases prior to September 2014. The metabolic concentrations and patterns of N-acetylaspartic acid (NAA), Choline (Cho), Creatine (Cr), NAA/Cr, NAA/Cho, and Cho/Cr ratios in radiotherapy-induced radiation encephalopathy by proton magnetic resonance spectroscopy were extracted. A meta-analysis was performed...
بیماری ورتیسیلیومی از مهمترین بیماری های پنبه کشور است که منجر به محدودیت کشت و کاهش عملکرد می شود. در تحقیق حاضر، از توکسین قارچ ورتسیلیوم (verticillium dahliae) به عنوان عامل گزینش سلول های بافت کالوس ارقام پنبه جهت تحمل به این بیماری استفاده شد. ریزنمونه ها از گیاهچه های سترون 7 روزه تهیه شدند و در محیط کشت ms به همراه دو میلی گرم بر لیتر از هورمون های naa و bap کشت شدند. پس از توزین اولیه،...
A micropropagation protocol was developed which may assist in the safeguarding and augmentation of dwindling natural populations of Clinopodium odorum (Griseb.) Harley, a critically and endangered medicinal plant. Factors affecting culture initiation bud sprouting and growth, rooting, and acclimatization were studied, using nodal segments of in vitro germinated seedling as primary explants on s...
BACKGROUND AND PURPOSE Proton MR spectroscopy has demonstrated reduced levels of N-acetylaspartate (NAA) in normal-appearing occipital and frontal regions of patients with acute nonpenetrating traumatic brain injury (TBI). We studied the relationship of frontoparietal NAA, choline (Cho), and creatine (Cr) to test the hypothesis that reduction in NAA is predictive of cognitive outcome. METHODS...
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...
Atopic (AA) and nonatopic (NAA) asthma are characterized by chronic inflammation and local tissue eosinophilia. Many C-C chemokines are potent eosinophil chemoattractants and act predominantly via the CCR3. We examined the expression of eotaxin, eotaxin-2, RANTES, monocyte chemoattractant protein-3 (MCP-3), MCP-4, and CCR3 in the bronchial mucosa from atopic (AA) and nonatopic (intrinsic; NAA) ...
