In order to evaluate the effect of plant growth regulators on sex determination and yield, an experiment was conducted by spraying different hormonal combinations on medicinal pumpkin. Experimental treatments were included different concentrations of NAA (25, 75, 100, 125 mg/l), paclobutrazol (50, 100, 200 and 300 mg/l) and combination of growth regulators (NAA 25 mg/l + PBZ 50 mg/l), (NAA 75 m...

Introduction NAA (N-acetyl-aspartate) is the second most abundant molecule in the CNS (after glutamate), its MRS signal is commonly used as a putative marker of viable neurones, and yet little is known about its function. Furthermore, recent data from cell culture has raised the possibility of an additional cellular contribution of NAA from nonneuronal origins, principally in isolated mature ol...

Impatiens is an ornamental member of family Balsaminaceae. This plant mostly propagated by vegetative technique, which generally time wasting process. It often multiplicities via seed but barricaded F1 sterility. In vitro culture walleriana has much significant function in fast proliferation with useful features and elicitation healthful disease-free plants. experiment was conducted to investig...

We report here a general synthetic strategy to encapsulate metal clusters within zeolites during their hydrothermal crystallization. Precursors to metal clusters are stabilized against their premature colloidal precipitation as hydroxides during zeolite crystallization using bifunctional (3-mercaptopropyl)trimethoxysilane ligands. Mercapto (-SH) groups in these ligands interact with cationic me...

PURPOSE To investigate neuronal dysfunction in the thalami of juvenile myoclonic epilepsy (JME) by using proton magnetic resonance spectroscopy (MRS). METHODS We performed single-voxel proton MRS over the right and the left thalami of 15 consecutive patients (10 women, 5 men) with JME (mean age 20.3 years) and 16 healthy volunteers (10 women, 6 men) (mean age 24.5 years). All patients had sei...

BACKGROUND AND PURPOSE It may be challenging to differentiate primary CNS lymphomas, especially primary CNS lymphomas with atypical MR features, from tumefactive demyelinating lesions by the use of conventional MR. This study aimed to investigate the usefulness of (1)H-MR spectroscopy for making this discrimination. MATERIALS AND METHODS Forty-four patients with primary CNS lymphomas and 21 w...

INTRODUCTION The accurate diagnosis and monitoring of idiopathic Parkinson disease (PD), a progressive neurodegenerative disorder, has not been fully developed. This study sought to identify a neurochemical profile in multiple regions of the PD brain and healthy controls by proton magnetic resonance spectroscopy (1H-MRS). We aimed to track changes of the brain neurochemical, quantify neuronal l...

N-Acetylaspartate (NAA) is employed as a non-invasive marker for neuronal health using proton magnetic resonance spectroscopy (MRS). This utility is afforded by the fact that NAA is one of the most concentrated brain metabolites and that it produces the largest peak in MRS scans of the healthy human brain. NAA levels in the brain are reduced proportionately to the degree of tissue damage after ...
