Purwaceng (Pimpinella alpina) is an herbal plant that has aphrodisiac, diuretic, and tonic properties. The imbalance between the growth exploitation of this makes it included in Appendix I (endangered), so its conservation will be crucial. One method tissue culture. This considered one way to induct callus. research objective find effect various treatments regulator concentrations NAA. 2,4 D co...

Introduction Dynamic C NMR spectroscopy combined with C label administration has been used to study brain metabolism non-invasively. N-acetyl aspartate (NAA) metabolism has been considered to be slow [1-3] and to have a similar turnover time as glycogen [3]. Most studies employed direct C detection to measure C label in NAA, with an additional external reference to calculate the isotopic enrich...

N-acetylaspartate (NAA) is an amino acid derivative present in high concentration in the brain. The function of NAA is still unsettled in spite of 50 years of research. The mainly neuronal synthesis and glial breakdown of NAA requires a well regulated neuronal efflux and glial uptake. In the present work hippocampal slices were used to study how NAA efflux from neurons is regulated and to furth...

Berginia ligulata is medicinally significant and endangered plant of the western Himalayan Region. This used to treat many diseases such as urinary problems heart problems. By using leaf explant, an efficient rapid micropropagation protocol was developed. In in-vitro propagation, MS medium supplemented with benzyl amino purine (BAP), 1-naphthalene acetic acid (NAA) indol-3-acetic (IAA) induce m...

Introduction N-acetyl-aspartate (NAA) is a major brain metabolite and its presence is used increasingly in clinical and experimental MRS studies as a putative neuronal marker. A reduction in NAA levels as assessed by in vim proton MRS has been suggested to be indicative of neuronal viability. However temporal observations of brain pathologies such as multiple sclerosis (MS), mitochondrial encep...

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 ...

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 (...
