The orientation imposed by the subject of this monograph leads us to emphasize those aspects of the chemistry of infection that may serve our understanding of the morphology of infection. Indeed, much of the effort expended in this field has been justified under a hypothesis that the genesis of the cytopathic effect is a biochemical lesion. How that lesion is inflicted by the virus, the ensuing...

The importance of developing artificial media that can be used in the place of serum for maintaining the life of tissues and organs outside the body hardly needs to be emphasized. Many of the studies for which the organ culture technique 1 was developed, as well as others that can be carried on by the simpler methods of tissue culture, depend for their success on the creation of suitable artifi...

in this study, physiological and morphological responses of five almond cultivars to drought stress were investigated under in vitro conditions. plantlets from five commercial almond cultivars (supernova’, ‘tuono’, ‘sahand’, ‘ferragnes ’ and ‘shahroud 21’] were established in ms medium containing 0.5 mg per liter bap and then subcultured  in ms proliferation medium containing 1 mg per liter bap...

who recommends artemisinin-based combination therapies (acts) as the most effective choice to treat malaria. for developing transgenic plants with high accumulation of artemisinin (by introducing genes encoding enzymes which regulate the biosynthetic pathway of artemisinin), an efficient protocol for tissue culture and plant regeneration is necessary. in the present study, leaf explants of arte...

objective: we studied both the presence of some carbohydrate compounds in a three-dimensional (3d) matrix harvested from human gingiva and the cell behavior in this matrix. materials and methods: in this experimental research, in order to prepare 3d scaffolds, human palatal gingival biopsies were harvested and physically decellularized by freeze-thawing and sodium dodecyl sulfate (sds). the sca...

plant tissue culture techniques are used as basic requirement of common plant transformation systems. in most cases of plant transformation, a reproducible regeneration protocol is the limiting step due to long time lasting, specialized facilities and well experienced persons. furthermore, tissue culture procedures induce somaclonal variation among regenerated transgenic plants. therefore, rece...
