Introduction: Mental foramen is an important landmark in mandible and knowledge regarding the actual location of mental foramen is important in dentistry. Materials &Methods: A total of 1172 digital panoramic radiographs were evaluated for assessment of the location of the mental foramen. The location was classified into six groups in relation to the apices of the premolars and first molar. R...

This study investigates the turbulent flows in simplified Dragon style river channels with a constant critical curvature and different single-short-branch characteristics, using an effective numerical method based on real geometry statistics. First, when branch outlet is closed, main channel, strong bed shear stresses are concentrated at inner bend apex downstream; as widens, more flow enters b...

We present results of a detailed study of X-ray flaring in the Z-track source Sco X-1 in a highly superEddington state made using high quality Rossi-XTE data from the PCA and HEXTE instruments. The emission model successfully used to explain the dipping LMXB, and other classes of LMXB in recent years, was applied to study the physical evolution along the Z-track which remains a major problem. T...

APEX nuclease is a mammalian DNA repair enzyme having apurinic/apyrimidinic (AP) endonuclease, 3'-5'-exonuclease, DNA 3' repair diesterase and DNA 3'-phosphatase activities. It is also a redox factor (Ref-1), stimulating DNA binding activity of AP-1 binding proteins such as Fos and Jun. In the present paper, a cDNA for the enzyme was isolated from a rat brain cDNA library using mouse Apex cDNA ...

We report a case of a 9 year old female child with congenital pseudarthrosis of the radius. She had a history of fractures of both bones of the left forearm after trivial trauma at the age of 7 years (2003) and 8 years (2004). On each occasion she was treated conservatively in a POP cast 4 weeks. She reported to us in January 2005 complaining of a gradually increasing deformity of the left fore...

DNA repair is required to maintain genome stability in stem cells and early embryos. At critical junctures, oxidative damage to DNA requires the base excision repair (BER) pathway. Since early zebrafish embryos lack the major polymerase in BER, DNA polymerase ß, repair proceeds via replicative polymerases, even though there is ample polb mRNA. Here, we report that Polb protein fails to appear a...
