Plants need to allocate some of their limited resources for defense against herbivores as well as for growth and reproduction. However, the priority of resource allocation within plants has not been investigated. We hypothesized that plants with extrafloral nectaries (EFNs) invest more chlorophyll around their EFNs-to support a high rate of carbon fixation there-than in other leaf parts of youn...

OBJECTIVES To evaluate whether the overgrowth of costal cartilage may cause pectus carinatum using three-dimensional (3D) computed tomography (CT). METHODS Twenty-two patients with asymmetric pectus carinatum were included. The fourth, fifth and sixth ribs and costal cartilages were semi-automatically traced, and their full lengths were measured on three-dimensional CT images using curved mul...

The prothoracic glands of early last (fifth) instar larvae of the silkworm are inactive with regard to ecdysteroidogenesis and unresponsive to prothoracicotropic hormone (PTTH) [J. Insect Physiol. 31 (1985) 455]. In an attempt to elucidate the hormonal mechanisms that cause the inactivity, we compared the effects of PTTH, dibutyryl cyclic AMP (dbcAMP), a cAMP phosphodiesterase inhibitor (IBMX),...

PURPOSE The purpose of this study was to compare the in vitro microleakage of fourth-generation filled and unfilled adhesive resin systems with fifth-generation filled and unfilled adhesive resin systems in both primary and permanent teeth. METHODS Eighty extracted or exfoliated human noncarious teeth (40 primary and 40 permanent) were assigned to each of 8 groups. Groups 1, 3, 5 and 7 were p...

In 2009, Griffith University School of Dentistry and Oral Health, in Queensland, Australia, introduced into its various curricula the concept of team-based treatment planning (TBTP), aiming to facilitate intraprofessional, interdisciplinary training and peer learning among its students. Fifty student teams were organized, each of which included students from three programs (Dental Science, Oral...
