This study was aimed to examine the changes in auditory event-related potentials (AERPs) and their relationship with brain metabolic changes in mild cognitive impairment (MCI). 34 MCI patients and 34 healthy elderly controls were subjected to auditory stimulus oddball task, and then post-stimulus potentials (P50, N100, P200, N200, and P300) were obtained, levels of N-acetylaspartate (NAA), crea...

To test for axonal damage or dysfunction in white matter tracts remote from acute demyelinating lesions, we used brain proton magnetic resonance spectroscopic imaging to measure changes in N-acetyl aspartate (NAA), an index of neuronal integrity, in the white matter of the normal-appearing hemisphere of three patients with large, solitary brain demyelinating lesions of the type seen early in mu...

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...

OBJECTIVE We performed (1)H-MR spectroscopy ((1)H-MRS) on multiple brain regions to determine the metabolite pattern and diagnostic utility of (1)H-MRS in multiple system atrophy (MSA). METHODS Examining single voxels at 3.0 T, we studied metabolic findings of the putamen, pontine base, and cerebral white matter in 24 MSA patients (predominant cerebellar ataxia (MSA-C), n = 13), parkinsonism ...

Rooting and shoot growth were evaluated on stem tip cuttings of砂pencumpe功ratum receiving various auxin soaking treatments. Five-cm-Iong stem tips (0.08 g fresh weight in average) were soaked in IAA, 1 BA, NAA and 2,4-D solutions at 5, 25 , 125μM for 10 min, and then placed in a rockwool block for three weeks. A deionized water soaking treatment was served as a control. The results indicated tha...

Tissue culture is an attractive alternative for plant propagation. Micropropagation is a technique to ensure a constant and uniform source of ornamental plants. Matthiola incana is an important ornamental species mainly cultivate by seed. Matthiola incana seeds were germinated on solid MS medium without plant growth regulators. Shoot proliferation and root formation are possible using kinetin (...

The experiment was conducted at Horticultural Farm, Sher-e-Bangla Agricultural University, during the period from October 2018 to February 2019 study application of nutrient sources interaction with NAA for higher growth and quality yield purple cabbage. consists two factors. Factor A: F0: control, F1: vermicompost (10 t/ha), F2: N180kg.ha-1; P66kg.ha-1 K75kg.ha-1 F3: ½ (5t. ha-1) + N90kg.ha-1;...

Objective: Alzheimer’s disease (AD) is a neural degenerative disease with progressive cognitive impairment. N-acetyl aspartic acid (NAA) is an important biomarker for assessing neuronal activity and brain cells metabolic abnormalities. This investigation is aimed to establish a liquid chromatography-mass spectrometry (LC-MS) method for measuring plasma NAA level, in order to make clear whether ...

Ecklonia maxima and the commercial biostimulants produced from it contain various plant growth regulators that are responsible for stimulation recorded in many crops. Auxins one of major contained E. extracts. The aim this research was to evaluate growth-promoting effect a seaweed extract on lettuce tomato transplant production under nursery conditions, compare with an equal concentration synth...

OBJECTIVE To assess birth outcomes in primiparous women with diagnosis of non-asthmatic atopy (NAA). Researchers hypothesised that women with NAA would have reduced the risk of adverse birth outcomes compared with women without NAA. NAA is defined as having allergic rhinitis and/or atopic dermatitis. SETTING Women were mostly treated in primary care settings in South Carolina, USA. PARTICIP...
