Flow cytometry and microsatellite analyses were used to evaluate the trueness-to-type of somatic embryogenesis-regenerated plants from six important Spanish grapevine (Vitis vinifera L.) cultivars. Tetraploid plants were regenerated through somatic embryogenesis from all of the cultivars tested with the exception of ‘Merenzao’. In addition, an octoploid(More)
In vitro chromosome doubling techniques have been used to produce polyploids in several species, including table grapes, but limited research in this field has been performed using winegrapes. An efficient procedure was established to induce tetraploid grapevine plants by colchicine treatment of embryogenic cell aggregates (ECAs) grown in winegrape cultivar(More)
In anterior cruciate ligament reconstruction with looped soft-tissue grafts, an interference screw is frequently used for tibial fixation. This study compared three alternatives thought to improve the initial mechanical properties of direct bioabsorbable interference screw fixation: suturing the graft to close the loop, adding a supplementary staple, or(More)
A finite element model of the carpal scaphoid and its joints was developed to study how wire positioning affects the initial stability of the fixation of scaphoid waist fractures using Kirschner wires. A transverse fracture of the scaphoid waist was simulated along with its fixation using five different two-wire configurations. The resulting models were(More)
BACKGROUND A Mediterranean dietary pattern has been associated with a reduced risk of coronary heart disease, as well as a reduction of oxidative stress, but studies indicating possible interactions between food intake and inflammatory mediators production at specific sites are lacking. AIM OF THE STUDY To assess the relationship between Mediterranean(More)
A model of the lumbar spine capable of taking into account realistic loads derived from human activity would be of great benefit in studying its normal biomechanical functioning as well as its in vivo behavior in injured and surgically altered states. This paper proposes a method to analyze the mechanical response of the lumbar spine subjected to loads(More)
The present work reports on a study of plant regeneration carried out with callus from the leaf blades and petioles of field-grown male adult kiwifruit plants (Actinidia deliciosa (Chev.) Liang and Ferguson). The cultivars used were ‘Tomuri’ and clone A, a selected male plant grown in north western Spain. The best shoot induction conditions were obtained in(More)
Somatic embryogenesis was induced from stamen filaments and an embryogenic suspension culture was established in the grapevine cultivar Mencía using thidiazuron and 2,4-dichlorophenoxyacetic acid. Four combinations of each growth regulator were assessed for somatic embryo induction in a basal medium containing Nitsch and Nitsch salts and Murashige and Skoog(More)
BACKGROUND Short central extensions which do not enter the tibial medullary canal are incorporated to cemented tibial components to increase initial stability in primary total knee arthroplasty. Their role in tibiae of differing preoperative mechanical quality has been little studied. METHODS Twelve embalmed cadaveric tibiae were paired and divided into(More)
Embryogenic suspension cultures are suitable for EMS mutagenesis in grapevine, and HRM prescreening of EMS-treated somatic embryo clusters allows rapid detection of point mutations before plant regeneration. Somatic embryogenesis is an excellent system for induced mutagenesis and clonal propagation in woody plants. Our work was focused on establishing a(More)
