The purpose of this study was to investigate the clinical role of proton magnetic resonance spectroscopy (1H-MRS) in the diagnosis of acute cerebral infarction. Using databases available at the Fifth Affiliated Hospital of Zhengzhou University (Zhengzhou, China), the medical records of 47 patients with acute cerebral infarction treated between April 2010 and March 2012 were retrospectively revi...
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...
Aerobic exercise is a promising form of prevention for cognitive decline; however, little is known about the molecular mechanisms by which exercise and fitness impacts the human brain. Several studies have postulated that increased regional brain volume and function are associated with aerobic fitness because of increased vascularization rather than increased neural tissue per se. We tested thi...
Date palm (Phoenix dactylifera L.) is propagated traditionally through offshoots or suckers, which usually appear at or below the ground level surrounding the stem base. However, there are many problems associated with this system. Offshoots are produced in limited number and vegetative propagation through them is slow, laborious, time consuming and expensive. The present study was conducted to...

The present study was conducted to induce callus from different in vitro grown seedling explants of shoot, root and leaf segments in order to develop shoot buds and rooting from callus. The sterilized seeds were cultured on Murashige and Skoog medium, and then the explants were cultured from seedling and transferred to an MS medium supplemented with different concentrations of BAP, kinetin, NAA...
Updated guidelines for the use of nucleic acid amplification tests in the diagnosis of tuberculosis.
Guidelines for the use of nucleic acid amplification (NAA) tests for the diagnosis of tuberculosis (TB) were published in 1996 and updated in 2000. Since then, NAA testing has become a routine procedure in many settings because NAA tests can reliably detect Mycobacterium tuberculosis bacteria in specimens 1 or more weeks earlier than culture. Earlier laboratory confirmation of TB can lead to ea...
Petunia (Petunia hybrida) is an ornamental plant species of high economic potential. One of the appropriate methods for propagation and breeding of petunia is tissue culture. This experiment was conducted to investigate the effects of different concentrations of benzyl adenine (BA) either alone or in combination with different concentrations of naphthalene acetic acid (NAA) on the regeneration ...
