This paper examines the differentiation of somites from stage-16 or -17 chick embryos cultured with or without notochord in explant cultures. Histological sections of the cultures were stained with a trichrome stain to identify the different kinds of connective tissues formed. Both anterior and posterior (epithelial) somites made muscle, cartilage and loose connective tissue in explant culture....

Hairy root culture is an effective method to produce secondary metabolites. In fact, hairy roots are genetically and biologically stable and also they are able to produce metabolites without hormones. Chicory (Cichorium intybus L.) is one of the most important medicinal plants with valuable medicinal compounds. In this research, hairy roots were induced by different Agrobacterium rhizogenes str...

Objective: To characterize the effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and arachidonic acid (ARA) in various combinations on indices of inflammation in recombinant porcine IL-1 beta stimulated porcine articular cartilage explants. Methods: Cartilage was obtained from the humeral-ulnar joints of Yorkshire x Landrace market sized gilts. Explants were harvested from t...

Curcumin (diferuloylmethane) is a phytochemical with potent Objective: anti-inflammatory and anti-oxidant properties, and has therapeutic potential for the treatment of a range of inflammatory diseases, including osteoarthritis (OA). The aim of this study was to determine whether non-toxic concentrations of curcumin can reduce interleukin-1beta (IL-1β)-stimulated inflammation and catabolism in ...

It is well established that during in vivo development the neurons of the avian ciliary ganglion are dependent for their survival on structures in the eye. Separate neuron populations innervate intraocular smooth and striated muscle targets. All ciliary neurons survive when cocultured with striated muscle. We demonstrate that when ciliary ganglion neurons are plated on explants of the choroid c...

In the present investigation, a micropropagation protocol has been developed for Vanilla borneensis Rolfe – critically endangered orchid through multiple shoot regeneration. Through in vitro regeneration from both nodal and tip explants, maximum (100%) induction was observed. The minimum time required bud observed (5–7 days) on medium supplemented with BAP (4.44 mM) + KIN (2.32 as compared to e...

Micropropagation of three genotypes of Indian mustard [Brassica juncea (L.) Czern.] using 7-days old seedling-derived transverse thin cell layer (tTCL) explants was accomplished. The genotype, explant source and addition of silver nitrate to the medium significantly influenced shoot bud induction. MS medium with 26.6 μM of 6-Benzylaminopurin (BAP) and 3.22 μM of 1-naphtaleneacetic acid (NAA) wa...

Batrachochytrium dendrobatidis, the causal agent of chytridiomycosis, is implicated in the global decline of amphibians. This chytrid fungus invades keratinised epithelial cells, and infection is mainly associated with epidermal hyperplasia and hyperkeratosis. Since little is known about the pathogenesis of chytridiomycosis, this study was designed to optimise the conditions under which primary...
