Endodontic surgical procedures involve the use of a root-end filling material to provide an apical seal and to facilitate the repair and regeneration of periradicular tissues. Whereas earlier studies typically evaluated the cytotoxicity of these materials, contemporary research has focused on their capacity to support a favourable cellular response. In vitro tissue culture techniques have demon...

Plant tissue culture comprises a set of in vitro techniques, methods and strategies that are part of the group of technologies called plant biotechnology. Tissue culture has been exploited to create genetic variability from which crop plants can be improved, to improve the state of health of the planted material and to increase the number of desirable germplasms available to the plant breeder. ...

In recent years, the possibility of developing numerous plantlets of many plant species in vitro has been realized. Termed plant tissue culture, this method of plant propagation has not been without problems when employed in commercial practice. One problem of major consequence has been bacterial contamination, usually becoming evident during later stages of tissue culture increase and multipli...

two separate factorial experiments were conducted to study the effects of explant sources, plant growth regulators, sucrose concentrations, and light conditions on in vitro cormlet formation of freesia (freesia ×hybrida bailey 'argenta'). interestingly, it was observed that the pupae had lower contamination levels compared to mother corms. using 40% sodium hypochlorite solution for 40 min, cont...

the use of healthy planting material is an important prerequisite for controlling destructive viral diseases in potato production. virus elimination methods such as meristem culture and thermotherapy are usually used to produce the nucleus stock of healthy planting material. here, we report a new technique of electrotherapy for elimination of two potyviruses, potato virus a (pva), and potato vi...

in vitro propagation of plant has played a very important role in rapidmultiplication of cultivars with desirable traits and production of healthy and disease-free plants. in the present investigation, the objectives were to optimize the micropropagation of rose hybrid ‘black baccarat’ cultivar. in proliferation step, the nodal segments (1.5 cm) was cultured on both liquid and solid media (ms, ...

background: numerous in vitro reports suggest that low level laser therapy (lllt) affects cellular processes by biostimulation, however most of them emphasize on using visible light lasers which have low penetration. the aim of this study was to determine the effect of infrared laser light (which is more useful in clinic because of its higher penetration) on secretion of fibroblast growth facto...

conclusions nucleic acid amplification tests (naats) are very appropriate in detection of infected individuals. detection techniques such as naats are independent of bacterial viability, and have a potential to limit false negative samples, therefore, in our country, the application of different laboratory diagnosis methods including naats with culture as gold standard for determination antimic...
