Distraction osteogenesis is one of the common procedures for limb lengthening. However, attempts are being made constantly to establish objective guidelines for early and safe removal of a fixator using a sensitive and quantitative measurement technique. Dual-energy X-ray absorptiometry (DEXA) has been evaluated in the past for understanding callus stiffness, and the present study is a step fur...

arnebia pulchra (willd. ex roem. & schult.) edm. is an endangered, perennial member of boraginaceae family. spectrophotometric and lc-mass analysis confirmed the existence of shikalkin derivatives in its root skin and polyphenolic compounds in the inner part of its root. studies on the regeneration of a. pulchra from its callus resulted in successful callus induction in the root explants excise...

BACKGROUND The management of plantar corns and callus has a low cost-benefit with reduced prioritisation in healthcare. The distinction between types of keratin lesions that forms corns and callus has attracted limited interest. Observation is imperative to improving diagnostic predictions and a number of studies point to some confusion as to how best to achieve this. The use of photographic ob...

Leaf and hypocotyl explants of 15 days old aseptically grown seedlings of Solanum laciniatum were cultured on MS medium supplemented with NAA (2 mg/l) and kinetin (0.5 mg/l) for callus initiation. For maintenance and proliferation of callus MS medium supplemented with 2,4-D (1 mg/l) and kinetin (0.5 mg/l) was used. The growth of the calli derived from hypocotyls increased with time of incubatio...

BACKGROUND Obtaining dedifferentiated cells (callus) that can regenerate into whole plants is not always feasible for many plant species. Sugar beet is known to be recalcitrant for dedifferentiation and plant regeneration. These difficulties were major obstacles for obtaining transgenic sugar beets through an Agrobacterium-mediated transformation procedure. The sugar beet line 'NK-219mm-O' is a...

in this study, responses of four canola genotypes to salt stress in germination test and callus culture stages were investigated. the response of genotypes under salinity levels was significantly different. higher salinity resulted in less germination and growth of seedling. after callus culturing on liquid saline media, callus fresh weight and callus induction efficiency were significantly dif...

Adenine phosphoribosyltransferase activity was measured in extracts of soybean (Glycine max var. Acme) callus and of senescing barley leaves (Hordeum distichon c.v. Prior). The enzyme from soybean callus had Michaelis constants for adenine and 5-phosphoribosyl pyrophosphate of 1.5 and 7.5 mum respectively and was inhibited by AMP and stimulated by ATP. The presence of kinetin was found to consi...

Spectrophotometric and LC-Mass analysis confirmed the existence of shikalkin derivatives in its root skin and polyphenolic compounds in the inner part of its root.

Agrobacteria mediated Coleus blumei tumour tissues were cultured in vitro on MS medium. Sixteen diversified transformed callus cultures were maintained for several years in the absence of plant growth regulators and antibiotics without affecting the growth rate. Rosmarinic acid was detected spectrophotometrically in all tissue lines but in different quantities. The highest rosmarinic acid accum...
