Fracture Callus in Osteopetrosis

Clinical Orthopaedics and Related Research, 1994
The 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.

New alternative in treatment of callus

The Journal of Dermatology, 2010
The pathological transformation of the skin into a thick and hard callus due to repetitive trauma or friction is commonly known as corn. Although a variety of medical and operative treatment choices have been proposed, an ideal treatment method is yet to be defined.

Organogenesis in Callus Culture

2003
Plant 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 ...

The initiation of callus and regeneration from callus culture ofTulipa gesneriana

Plant Cell, Tissue and Organ Culture, 1996
Cold treatment of seeds, obtained from crosses between cultivars ofT. gesneriana L., affects the developmental stage of embryos, which in turn influences the frequency of callus induction and the development of different callus types. Cold-treated, mature embryos and basal segments ofin vitro-derived bulblets, were suitable explants for the initiation ...

Electrical Callus and Callus Formation by Electret

Clinical Orthopaedics and Related Research, 1977
The 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.

Callus Stimulation in Distraction Osteogenesis

Plastic and Reconstructive Surgery, 2002
Distraction 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.

The bony callus

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.

Callus formation and cucurbitacin B accumulation in Ecballium elaterium callus cultures

Fitoterapia, 2003
Ecballium 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.

Callus Cultures of Arabidopsis

Current Protocols in Microbiology, 2006
AbstractProtoplasts are plant cells lacking cell walls. They can be generated from stationary callus cultures derived from Arabidopsis thaliana seedlings. After treatment of the callus with cellulase and pectinase, protoplasts are inoculated with viral RNAs using polyethylene glycol.
