Agenesis and hypodontia are associated with crown-size reduction in the remaining teeth (S. M. GARN ET AL, J Dent Res 41:717, 1962, Nature 200:488-489, 1963; J Dent Res 42:13441363, 1963; H. J. KEENE, Amer J Orth 50: 445-451, 1964; and K. HANIHARA ET AL, J Anthrop Soc Nippon 73:72-81, 1965). The question arises as to whether crown-size reduction associated with tooth number reduction is uniform...

BACKGROUND AND PURPOSE The distal dural ring (DDR) represents the anatomic border between the extradural and intradural internal carotid arteries (ICAs). The purpose of this study was to examine whether 3D-MR cisternography and MR angiography (MRA) fusion images can identify the boundary between the CSF and the cavernous sinus, which might represent the DDR. MATERIALS AND METHODS Thirty-six c...

Several plant and animal species of agricultural importance are commercialized as hybrids to take advantage of the heterosis phenomenon. Understanding the genetic architecture of hybrid performances is therefore of key importance. We developed two multiparental maize (Zea mays L.) populations, each corresponding to an important heterotic group (dent or flint) and comprised of six connected bipa...

Maxillary and mandibular dentitions exhibit correspondences to a truly remarkable degree. Correlations of upper and lower opponents (isomeres) in both the deciduous and permanent dentitions are exceeded only slightly by right-left (antimere) correspondences, both in crown size (Garn and Burdi, J Dent Res 50:1407, 1971) and in tooth emergence timing (Garn and Smith, J Dent Res, in press, 1980). ...

Lowe syndrome and Dent-2 disease are caused by mutation of the inositol 5-phosphatase OCRL1. Despite our increased understanding of the cellular functions of OCRL1, the underlying basis for the renal tubulopathy seen in both human disorders, of which a hallmark is low molecular weight proteinuria, is currently unknown. Here, we show that deficiency in OCRL1 causes a defect in endocytosis in the...

We report three experiments comparing con®dence judgments made by actors and by observers. In Experiment 1, actors generated qualitative answers (countries of the world) in a country-identi®cation task; in Experiment 2, actors generated quantitative answers (years) in a historical event-dating task. Both actors and observers indicated their con®dence in the actors' answers. Actors were signi®ca...

Dental trauma can result in tooth loss despite best efforts at retaining and maintaining compromised teeth (Dent Traumatol, 24, 2008, 379). Upper anterior teeth are more likely to suffer from trauma, and their loss can result in significant aesthetic and functional problems that can be difficult to manage (Endod Dent Traumatol, 9, 1993, 61; Int Dent J 59, 2009, 127). Indeed, teeth of poor progn...

Multiple Input Multiple Output (MIMO) has become one of the most exciting field in modern engineering.It has become one of the key technologies for wideband wireless communication systems.It is mainly used to increase capacity and data rate of any wireless systems.In this paper,we exploit the space and time diversity to decode the quasi and rotated quasi space time block codes (QOSTBC) based on...

Intercorrelations and communalities are now well known for tooth formation (Garn et al., J Dent Res 39:1049, 1960), crown size of the permanent teeth (Moorees and Reed, Arch Oral Biol 9:685, 1964; Garn et al., J Dent Res 44:350, 1965), the deciduous teeth (Garn et al., JDentRes 56:1214, 1977), and crown size of deciduous teeth during odontogenesis (Garn et al., J Dent Res 58:554, 1979). However...
