Zeolites are crystalline microporous materials with well-defined and uniform pore structure that find extensive industrial uses as adsorbents, catalysts and ion exchangers [1-2]. Zeolite films supported on different materials have been successfully prepared and have potential applications as highly selective membrane separators, membrane reactors, chemical sensor and microdevices [3-10]. Most o...

Luffa cylindrica belongs to the family cucurbitaceae is an economically important plant widely grown for its vegetable purpose,but the plant as a whole is able to cure many of the skin diseases,thus possess medicinal importance also. In the present study callus multiplication of the luffa from the leaf explant have been investigated with different concentrations of auxin (NAA) with cytokinine (...

Chrysanthemum nodal explants were cultured on 1⁄2 X MS medium containing different combinations of growth hormones. A reasonable callus formed on explants when MS contained 0.5 mg. cm each of BAP and NAA after about 3 weeks. Similar results were obtained on MS + 0.5 mg. cm BAP + 0.1 mg. cm NAA or 1.0 mg. cm BAP + 0.1 mg. cm NAA. A maroonish embryogenic callus was formed on MS containing BAP onl...

Canavan disease (CD) is an autosomal recessive disorder, characterized by spongy degeneration of the brain. Patients with CD have aspartoacylase (ASPA) deficiency, which results accumulation of N-acetylaspartic acid (NAA) in the brain and elevated excretion of urinary NAA. Clinically, patients with CD have macrocephaly, mental retardation and hypotonia. A knockout mouse for CD which was enginee...

The growing demand for rapid diagnosis of tuberculosis (TB) has led to the incorporation of nucleic acid amplification (NAA) tests in case definitions. The objective of this study was to evaluate the contribution of a real-time polymerase chain reaction (PCR) assay in providing a result predictive of a confirmed TB case. Respiratory and extra-pulmonary specimens (n = 308) were subjected to NAA...

Abstract Background The thalamus is crucial in the development of idiopathic generalized epilepsy (IGE), which could lead to cognitive dysfunctions, according data from neuropsychology and advanced neuroimaging investigations. This research aimed measure metabolic changes assess if be contributed impairment IGE patients. Thirty patients thirty healthy volunteers with matched ages, genders, educ...

A method is described that allows the in vivo differentiation of N-acetyl aspartate (NAA) from N-acetyl aspartyl glutamate (NAAG) by in vivo MR spectroscopy (MRS) at 3 Tesla (3T). The method, which is based on MEGA-point-resolved spectroscopy (PRESS) editing, selectively targets the aspartyl spin system of one species while deliberately removing the other species from the spectrum. This allows ...

BACKGROUND Previous neuropathological and neuroimaging studies have documented neuronal loss in the hippocampal region in schizophrenia. N-acetylaspartate (NAA) is a neuronal/axonal marker that may be utilized to assess neuronal loss or dysfunction by proton magnetic resonance spectroscopy (1H MRS). This study measured NAA, choline, and creatine in the hippocampal region of patients with schizo...

Strawberry is a valuable, nutritious, and economically important fruit all over the world including Bangladesh. Therefore, there is a demand to develop a suitable variety of strawberry. For this purpose, leaf explants from in vitro grown strawberry plantlets were cultured onto MS medium supplemented with different concentrations and combinations of 2,4-D, NAA and BA for callus induction. The mo...
