considering great medicinal value of hyssopus officinalis l. and possibility of its mass production through in vitro culture, two individual experiments was conducted. effect of various concentrations (0, 2.2, 4.4 and 11 µmol) of tdz and bap in combination with 1 µmol of iaa on direct regeneration from nodal explants were assessed. significant difference between treatments was observed (p≤ 0.01...

A number of studies report that epithelial to mesenchymal transition (EMT) supports the generation and maintenance of cancer stem cells (CSCs), which show tumor seeding ability and drug resistance; however, the molecular mechanisms underlying induction of EMT-associated tumor malignancy remain unclear. The present study reports that oral cancer cells switch from expressing the CD44 variant form...

induction heating is widely used in metal industry for melting or heating thin slabs in a continuous casting plant. the wide application is based on good efficiency, high production rate and non-polluting conditions. for designing a parallel resonant induction heating system, calculating the capacitance for the resonant circuit is important, because its value affects resonance frequency, output...

background resistance exercise is recommended as a useful therapeutic tool for the treatment of type 2 diabetes (t2d); however, the frequency of studies is inadequate to establish the precise mechanisms of any association between them. objectives in this study, we aimed to assess the effect of three months of resistance training on tcf7l2 expression in pancreatic tissues, serum insulin and gluc...

Direct Torque controlled induction motor (DTC-IM) drives use stator resistance of the motor for stator flux estimation. So, stator resistance estimation properly is very important for a stable and effective operation of the induction motor. Stator resistance variations because of changing in temperature make DTC operation difficult mainly at low speed. A method based on artificial neural networ...

ABSTRACT Selected strains of nonpathogenic rhizobacteria can induce a systemic resistance in plants that is effective against various pathogens. In an assay with bean plants, we investigated which determinants of the rhizobacterium Pseudomonas aeruginosa 7NSK2 are important for induction of resistance to Botrytis cinerea. By varying the iron nutritional state of the bacterium at inoculation, it...

TCV (Turnip crinkle virus) coat protein is required for the resistance response in Arabidopsis thaliana Di-17 plants. An aspartate→asparagine mutation at amino acid four of the coat protein is sufficient to result in resistance-breaking. To determine the essential chemical properties responsible for the induction of resistance, a series of site-directed mutants were produced. Serine as well as ...

Plant inoculation with endophytic bacteria that normally live inside the plant without harming the host is a highly promising approach for biological disease control. The mechanism of resistance induction by beneficial bacteria is poorly understood, because pathways are only partly known and systemic responses are typically not seen. The innate endophytic community structures change in response...
