An efficient protocol is suggested for in vitro culture of five Phalaenopsis hybrids obtained by hand-cross-pollination of three commercial hybrids Calgary, Ankara, and Kendall. Four nutrient media- namely half-strength Murashige and Skoog, Knudson, Phytamax containing activated charcoal, and Mitra– once supplemented (with coconut water, peptone, or both), and once without any supplement were c...

background: promastigotes of leishmania spp. have been readily cultured, but the axenic culture of amastigotes has been successful in l. donovani , l .infantum l. mexicana and l. pifanoi . however, some species such as l. major, is much less amenable to axenic cultivation. in present study, we describe an in vitro culture system for the generation and propagation of axenic amastigotes form of l...

garlic, an antioxidant plant, can react with amino groups of proteins to form schiff bases. as diabetes leads to glycation of various proteins and this in turn has some effects on the structure of proteins and biochemical activity of them, the inhibition of this process seems very vital. for several years researchers in this field have done their best to recognize the antidiabetic compounds. th...

conclusions these results indicate that a. kellalensis extracts exert potent anti-rotaviral activity only after viral adsorption. the two extracts from a. kellalensis showed a good selectivity index. also these results suggest that extracts prepared from the flowers of a. kellalensis may be potential anti-rotaviral agents in vivo and be useful in veterinary medicine. background achillea kellale...

materials and methods the subjects included 27 male and 3 female patients with advanced chronic periodontitis. the mean age of the patients was 47.6 ± 2.0 years old. p. gingivalis was isolated from the samples and identified by various diagnostic tests, including gram staining, indol test, and fluorescent test. minimum inhibitory concentration (mic) of the essential oil against isolated p. ging...

Borrelia microtti and Borrelia persica are two Iranian strains of spirochetes whose vectors are Ornithodorous tholozani and Ornithodorous erraticus which are responsible for relapsing fever. BSK medium has been used for in vitro culture of other strains of borrelia, although the two mentioned strains could not be successfully cultured in it. We have modified BSK medium by using guinea pig ...
