To the Editor—We thank Dr. Dylewski [1] for the feedback on our article [2]. It is understood that the usefulness of nucleic acid amplification (NAA) tests varies with the prevalence of the disease among the population being tested. In our article, we do not advocate NAA testing for all specimens submitted for culture. For patients whose specimens have negative acid–fast bacilli (AFB) smear res...

Orchids have a long period of production and need to be under the right conditions. Therefore, in vitro propagation is an alternative reduce time. This study aimed determine optimal conditions two species orchids, Cattleya maxima Lindl. Phalaenopsis amabilis (L.) Blume. For this goal, experiments were carried out: multiplication rooting, for both species. In experiment, treatments differentiate...

In vitro asymbiotic seed germination of Dendrobium chrysotoxum varied with fruit harvesting time and culture medium used for germinating seeds. Seeds at different developmental stages were harvested and cultured on five asymbiotic orchid seed germination media i.e. defined and undefined media, namely 1⁄2 MS, KC, M, MS and PDA. Seeds harvested 220 days after pollination showed maximum germinatio...

OBJECTIVE To apply in vivo proton magnetic resonance spectroscopy imaging estimates of N-acetylaspartate (NAA), a neuronal marker, to clarify the relative contribution of neuronal and glial changes to the widespread volume deficit of cortical gray matter seen in patients with schizophrenia with magnetic resonance images. METHODS Ten male veterans meeting criteria of the DSM-IV, for schizophre...

BACKGROUND Nucleic acid amplification (NAA) testing for Mycobacterium tuberculosis (MTB) offers improved diagnostic accuracy, compared with smear microscopy, in differentiating MTB from other mycobacteria. We aimed to evaluate the reliability and projected impact of NAA testing in patients with acid-fast bacilli (AFB) smear-positive respiratory samples. METHODS We identified a retrospective c...

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...

In the present study, seed production was carried out during 2016 and 2017 in newly released cytoplasmic genetic male sterility (CGMS) based chilli (Capsicum annuum) hybrid. The objective of this study to enhance quality for hybrid using given treatments field. experiment conducted at Department Seed Science Technology, University Agricultural Sciences, Raichur, Karnataka laboratory field condi...

An efficient in vitro regeneration protocol has been developed from shoot tips of Drosera burmannii Vahl., a carnivorous plant of north-east India. Various plant growth regulators were used to study their efficacy in the induction of multiple shoots and roots. Of the various treatments, the maximum number of shoots (28.8 ± 1.5) and roots (9.7 ± 0.6) was observed in one-fourth strength standard ...

In this research, a factorial 4×3×4 with 4 replications in Completely Randomized design was used to study the effects of different auxin treatments (4 levels), pH(2 levels) and cultivars (3 levels) on regeneration and rooting of in vitro shoot tips excised from shoots cultured on media supplemented with 1.5-2 mg/l BA. The results showed both auxins (NAA and IBA) produced callus in the bases of ...

Among subtropical fruits Ber (Zizyphus mauritiana L.) one of the most common fruit crop, grown under neglected soil types. It is a drought hardy and can grow hazardous conditions soil, water climate thus it has rightly been recommended for arid desert area India [1]. found growing wild as well in cultivated forms throughout warmer regions up to an altitude 1500 metres above Mean Sea Level. The ...
