PIWOWARCZYK BARBARA, PINDEL ANNA, MUSZYŃSKA EWA. 2016. Callus Induction and Rhizogenesis in Lathyrus sativus L. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 123–128. Grass pea (Lathyrus sativus L.) is a leguminous plant distinguished by great resistance to abiotic and biotic stresses that can become a valuable source of protein feed in the nearest future. Howev...

OBJECTIVES This study compared callus formation in distal femur fractures stabilized with locking plates and intramedullary nails to test the hypothesis that locking plates induce less fracture callus than IM nails. DESIGN Retrospective case matched study. SETTING Two orthopaedic trauma centers. PATIENTS 174 distal femur fracture were reviewed to extract cases treated with retrograde IM n...

Wild pistachio (Pistacia atlantica subsp. kurdica) is one of tree species that cover much of the forest in northwest of Iran and used in industries, medicine and as food. The present study describes callus induction of the P. atlantica subsp. kurdica using seedling stem explants and the influence of different plant growth regulators including kinetin, benzyladenine (BA), thidiazuron (TDZ), 6Ben...

Mice in which Cbl is unable to bind PI3K (YF mice) display increased bone volume due to enhanced bone formation and repressed bone resorption during normal bone homeostasis. We investigated the effects of disrupted Cbl-PI3K interaction on fracture healing to determine whether this interaction has an effect on bone repair. Mid-diaphyseal femoral fractures induced in wild type (WT) and YF mice we...

Non-invasive assessment of fracture healing, both in clinical and animal studies, has gained favour as surrogate measure to estimate regain of mechanical function. Micro-computed tomography (µCT) parameters such as fracture callus volume and mineralisation have been used to estimate callus mechanical competence. However, no in-depth information has been reported on microstructural parameters in...

Extensive limb lengthening may be indicated in achondroplastic patients who wish to achieve a height within the normal range for their population. However, increasing the magnitude of lengthening is associated with further complications particularly adjacent joint stiffness and fractures. We studied the relationship between the magnitude of femoral lengthening and callus pattern, adjacent joint...

In order to investigate the genetic variation in tissue culture response and to ®nd the cultivars with high regeneration ability for genetic transformation, twenty®ve turf-type tall fescue (Festuca arundinacea Schreb.) cultivars, including many elite ones released recently, were evaluated for their callus induction and plant regeneration responses. Callus induction was initiated from mature see...

Introduction A unilateral external fixator comprises of a collection of pins, clamps and sidebars to form a construct on one side of the limb that can be used to stabilise bone fractures and promote healing. An external fixator can allow the operator to alter the flexibility of the fixation. In the presence of flexible fixation, fracture healing happens through the creation of callus, which mec...

Fourier transform infrared spectroscopic imaging (FTIRI) was used to study bone healing with spatial analysis of various callus tissues in wild type mice. Femoral fractures were produced in 28 male C57BL mice by osteotomy. Animals were sacrificed at 1, 2, 4, and 8 weeks to obtain callus tissue at well-defined healing stages. Following microcomputerized tomography, bone samples were cut in conse...

Stevia rebaudiana Bertoni that conventionally propagated by seed or by cuttings or clump division which has a limitation of quality and quantity seed material. In present study, callus culture technique was tried to achieve rapid plant multiplication for quality seed material. Callus induction and multiplication medium was standardized from nodal as well as leaf sagments. It is possible to main...
