Electrical Callus and Callus Formation by Electret
Clinical Orthopaedics and Related Research, 1977The callus formed by passing an electric current through bone is called electrodynamic callus. The amount of electrical current determines the quality of the callus (osseous, cartilagenous, or fibrous). Callus forms first at the negative pole and grows toward the positive pole.

Injury, 1997
The bony callus was investigated by staining with the PAS and von Gieson techniques. The callus appeared to be composed of two adjoining but distinct types of bone. The birefringence observed in the periosteum and callus cartilage revealed different sized collagen fibres, each oriented perpendicularly to the long axis of the diaphysis.

First Metatarsal Callus Distraction
Journal of the American Podiatric Medical Association, 2008We describe the results in seven patients who underwent surgery to lengthen a short first metatarsal via callus distraction. The increased length achieved ranged from 13 to 48 mm, with an average of 20.2 mm. The technique was successful in restoring length and improving symptoms, although several complications were encountered.

Fracture Callus in Osteopetrosis
Clinical Orthopaedics and Related Research, 1994The histologic features of bone callus after a traumatic fracture in a patient with osteopetrosis are presented. The fracture callus develops in stages that are apparently normal. The tissue is initially rich in bone-forming cells and vessels. One year later, however, unlike mature osteopetrotic bone, the tissue shows no Haversian organization.

Callus Stimulation in Distraction Osteogenesis
Plastic and Reconstructive Surgery, 2002Distraction osteogenesis has been described as in vivo tissue engineering. The ability to stimulate this process for the repair of bony defects or lengthening of congenitally shortened facial structures is likely to significantly impact the field of craniofacial surgery.

Organogenesis in Callus Culture
2003Plant cells can be totipotent, i.e., each cell may be capable of developing into an entire plant when provided with the correct environmental stimuli. Research during the last 30 yr has demonstrated that successful organogenesis in callus cultures can be achieved by the correct choice of medium components, selection of a suitable inoculum, and control ...

Callus formation and cucurbitacin B accumulation in Ecballium elaterium callus cultures
Fitoterapia, 2003Ecballium elaterium fruit juice is used for the treatment of sinusitis in Turkish folk medicine. The aim of this study was to increase the yield of cucurbitacin B, an anti-inflammatory compound previously isolated in various organs of E. elaterium, through tissue culture techniques.

Sugarbeet ( Beta vulgaris L.): shoot regeneration from callus and callus protoplasts
Planta, 2003The successful application of recombinant DNA technology for crop plants requires efficient regeneration systems. A detailed study on the regeneration potential of callus and callus-derived protoplasts of a recalcitrant species, sugarbeet, was performed.

Canadian Journal of Botany, 1969
Cyclamen persicum callus cultures have been established on a defined medium. The tissue requires an auxin and a cytokinin. Adenine, while not required, greatly stimulates growth. The callus grows more vigorously in the dark than in light. After more than 6 years of subculture, the callus retains the capacity to form roots and shoots.
