Weak decays of the vector $D^{*0}$ and $B_{(s)}^{*0}$ mesons to $\mumu$ final state provide novel potential test Standard Model particle physics. Such processes have extremely small branching fractions as are able decay through electromagnetic (for meson) strong interactions. Nonetheless, production copious quantities these particles in LHC collisions, ability exploit experimental techniques th...

a 16-year-old class ii female patient was treated without tooth extraction. the upper first molars were distalized by the pendulum appliance. after six months, the molars tipped significantly to the distal. to correct this side effect, we decided to upright the molars using skeletal anchorage. on each side, a mini-screw was inserted between first and second premolars in the buccal cortical plat...

Integration of the human immunodeficiency virus type 1 (HIV-1) cDNA into the genome of a human cell is an essential step in the viral replication cycle. Understanding of the integration process has been facilitated by the development of in vitro assays using specific oligonucleotides and recombinant integrase. However, understanding of the biology of retroviral integration will require in vitro...

Conditional gene targeting strategies are progressively used to study gene function tissue-specifically and/or at a defined time period. Instrumental to all of these strategies is the generation of targeting vectors, and any methodology that would streamline the procedure would be highly beneficial. We describe a comprehensive transposition-based strategy to produce gene-targeting vectors for t...

background. orthodontic mini-implants provide skeletal anchorage for tooth movement. there are two designs of mini-implants, tapered and cylindrical, which exhibit different clinical characteristics, including possible micro-damage to cor-tical bone. complications such as peri-implantitis and pain after mini-implant placement are common. the aim of this study was to evaluate the effect of mini-...
