BACKGROUND: In order to investigate the induction of salinity tolerance in CP72-1312 commercial cultivar in tissue culture condition, an experiment was carried out in the tissue culture laboratory of Karoun Agro-Industry Company in 2017 year. OBJECTIVES: At this study we evaluated tolerance of CP73-1312 sugarcane commercial cultivar to salt stress in tiss...

The outcome of a bone fracture partly depends upon the mechanical environment experienced by the fracture callus (reparative tissue) during the healing. Therefore biomechanics of bone fracture healing has been examined in many clinical or biological, mathematical or finite element studies (Cheal et al. 1991, DiGioia et al. 1986, Claes et al. 1999, Doblaré et al. 2004 and Oh et al. 2010). Most o...

Healing of the bone is different with the other part of the body. Fracture healing is actually a bone regeneration with no scar tissues, where as in wound healing, injured tissue is replaced by  connective tissue which became a scar, Traditionally fracture healing is divided in to 4 stages: 1) Stage of inflammation; 2) Stage of soft callus; 3) Stage of hard callus and 4) Stage of remodeling. In...

Background. Among the drugs that have a pleiotropic effect on bone, attention is drawn to alfacalcidol – precursor of active form D-hormone. There are studies revealed distinctive features bone regeneration in osteoporosis and young animals. The purpose was study after treatment with senile Materials methods. A transcortical defect from lateral medial femur modeled rats aged 24 months area meta...

findings in relation to the inhibitory effects of natural substances against microorganisms showed that herbal products may be alternatives to synthetic and chemical drugs due to their significant therapeutic effects. the pennyroyal ( mentha pulegium ) as an important medicinal plant, belongs to the lamiaceae family is applied in the pharmaceutical and food industries. in recent years, plant ti...

We are interested in the cellular physiological events taking place during shoot regeneration in rice (Oryza sativa L. cv. Tainan 5) callus induced by osmotic stress. At first, the sucrose and starch metabolisms in rice callus were studied because carbohydrates are the main energy source in plant tissue culture. The results showed that fresh weight, water content, cellular water, and osmotic po...

Callus cultures established from Phaseolus vulgaris seedlings were used to investigate hormonal influence on lectin biosynthesis. The plant tissue cultures were initiated using defined levels of both a cytokinin (kinetin) and an auxin (2,4-dichlorophenoxyacetic acid) and were then transferred to media containing different amounts of these hormones. The lectin content of each callus culture was ...

The effects of eight different narrow band-emitting fluorescent lamps (371-750 nm) and four commercial broad band-emitting fluorescent sources upon growth and shoot initiation in tobacco callus (Nicotiana tabacum var. Wisconsin 38) have been characterized. Wavelength and intensity are equally important parameters in determining morphogenic changes. Near ultraviolet light (371 nm) was found to s...

Among the flowering plants, the members of cucurbitaceae are duly useful for human being that is agood source of vegetables and also a better resource for phytochemical compounds. The present study was aimed to induce the callus from in vitro grown seedling explants. The effect of BAP and NAA have been investigated, the combination of BAP and NAA results in the higher callus induction. The call...
