Since the diamine putrescine can be metabolized into the pyrrolidine ring of tobacco alkaloids as well as into the higher polyamines, we have investigated the quantitative relationship between putrescine and these metabolites in tobacco callus cultured in vitro. We measured levels of free and conjugated putrescine and spermidine, and pyrrolidine alkaloids, as well as activities of the putresci...

INTRODUCTION The combination of traumatic brain injury (TBI) and long-bone fracture leads to increased formation of callus and mineral density in wild-type (WT) mice. However, this effect was not detected radiologically in leptin-deficient mice. Due to the complex interactions between hormonal and bone metabolism and the important role of leptin in this setting, our aim was to investigate morph...

St Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] is an important warm season turf and pasture grass. In vitro tissue culture of St Augustinegrass could serve as an important mean for its improvement through genetic transformation as well as induced somaclonal variation. To optimize tissue culture conditions for plant regeneration of St Augustinegrass, tissue culture responses of 11 ex...

Background/Aim. Recent studies indicate that adipokines have an important role in bone physiology and pathology. data adipokine leptin functions as a regulator of growth at multiple levels, systemically locally. So far, it has been shown influences volume mineral density population with metabolic and/or hormonal abnormality. Data concerning values non-obese children fractures are scarce. Method...

Grade 1 open spiral fracture of left tibia in a 1.5 year-old horse was treated using a combination of 4.5 mm locking compression plate (LCP) and a dynamic compression plate applied in a neutralization manner. The open wound was managed postoperatively by regular dressing and lavage. Radiograph at 24 days post-treatment revealed callus formation and at two months complete bridging callus was obs...

Introduction Various compounds are being sought to increase fracture healing and enhance the healing rate. The closed femoral fracture in rats is a model commonly used to assess the efficacy of a compound for healing. This model is considered as a presumably stabilized fracture healing process. In a normal fracture healing process, there are 4 stages, i.e., inflammatory reaction and hematoma im...

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...

The present study was aimed at the development of a somoclonal variant and isozyme marker for Phyllanthus amarus Schum & Thonn using inter-nodal segments and the enzyme peroxidase. Maximum callus proliferation was obtained on Murashige and Skoog’s medium supplemented (MS) with 1.0 mg/l of 2,4-Dichlorophenoxyacetic acid. Three weeks-old pale yellowish white semi-friable callus was used for organ...
