BACKGROUND AND PURPOSE SIACI of bevacizumab has emerged as a promising novel therapy in the treatment of recurrent GB. This study assessed the potential of (1)H-MRS as an adjunctive technique in detecting metabolic changes reflective of antiproliferative effects of targeted infusion of bevacizumab in the treatment of GB. MATERIALS AND METHODS Eighteen patients enrolled in a phase I/II study o...

We sought to determine whether neuronal dysfunction throughout the temporal lobes of children with temporal lobe epilepsy (TLE) is already as severe at the time of diagnosis as it is in patients with long-standing intractable TLE (INT-TLE). Proton magnetic resonance spectroscopic imaging was used to measure N-acetylaspartate/creatine (NAA/Cr) ratios in the temporal lobes of five consecutive chi...

PURPOSE To investigate possible neuronal dysfunction of the thalamus in patients suffering from typical absence epilepsy, using magnetic resonance spectroscopy (MRS). Special attention was paid to levels of N-acetylaspartate (NAA) and creatine (Cr), and to the NAA/Cr ratio. METHODS MRS was performed over the right and left thalamus in nine patients suffering from typical absence epilepsy, and...

BACKGROUND AND PURPOSE The perceived safety of the recreational drug methylenedioxymethamphetamine (MDMA), or Ecstasy, conflicts with animal evidence indicating that MDMA damages cortical serotonin (5-HT) neurons at doses similar to those used by humans. Few data are available about the effects of MDMA on the human brain. This study was designed to evaluate MDMA-related alterations in metabolit...

Background: Imbalances in cellular energy homeostasis can lead to diseases such as type 2 diabetes, cardiovascular disease and cancer. The heart, which has to contract incessantly, is very sensitive to nutritional changes and requires optimal energy to fuel adjustment [1]. N-acetylaspartate (NAA) is one of the most abundant metabolites in brain [2] with yet unknown function. NAA is synthesized ...

N-acetylaspartate (NAA) quantification by 1H-magnetic resonance spectroscopy has been commonly used to assess in vivo neuronal loss in neurodegenerative disorders. Here. the authors used ex vivo and in vivo 1H-magnetic resonance spectroscopy in rat and primate models of progressive striatal degeneration induced by the mitochondrial toxin 3-nitropropionate (3NP) to determine whether early NAA de...

Background: Chrysanthemum; also commonly known as mums or chrysanths, is one of the most important ornamental crops worldwide. Introducing desirable traits into this valuable plant by the conventional breeding has so far been faced with some restrictions due to the limited gene pool and cross-incompatibility. Therefore, breeders have decided to exploit Agrobacterium-mediated tr...

Achillea species are of high medicinal value based on their use in traditional medicine and content secondary metabolites with potential application dermatology cosmetic industry. occulta is a single-mountain local prioritized vulnerable Greek endemic encountering propagation problems through seeds root division. In vitro can be used for the rapid mass production clonal plants complying phytoch...

The present study was conducted to investigate the effect of growth regulator NAA on in vitro shoot proliferation, rooting, and plantlet establishment. Among the different concentrations of NAA, the best increase in shoot weight (0.25 g) and shoot number (8.83) were observed from 0.1 mg/I NAA. The highest shoot length (2.60 cm), number of leaves (4.83), number of roots (5.15), and root length (...
