ABSTRACT
The complete mitogenome sequence of the lesser bandicoot rat (Bandicota bengalensis Gray and Hardwicke, 1833) was determined using long PCR. The genome was 16,327 bp in length and contained 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, 1 origin of L strand replication and 1 control region. The overall base composition of the heavy strand is A (34.2%), C (24.9%), T (28.5%) and G (12.4%). The base compositions present clearly the A-T skew, which is most obviously in the control region and protein-coding genes. Mitochondrial genome analyses based on MP, ML, NJ and Bayesian analyses yielded identical phylogenetic trees. This study verifies the evolutionary status of Bandicota bengalensis in Muridae at the molecular level. The mitochondrial genome would be a significant supplement for the Bandicota bengalensis genetic background. The two Bandicota species formed a monophyletic group with the high bootstrap value (100%) in all examinations.
ABSTRACT
<p><b>OBJECTIVE</b>Clinical cases of immediate loaded implants were retrospectively analyzed, in the aim of evaluating the clinical value of immediate loading.</p><p><b>METHODS</b>From July 2005 to October 2009, 99 immediate loaded implants were implanted in 29 patients. The overall data including radiography, clinical examination were collected during the follow-up periods ranged from 4 to 46 months. The implants were evaluated with the survival rate, bone resorption, soft tissue esthetics (including gingiva papilla index and pink esthetic score).</p><p><b>RESULTS</b>Survival rate for immediate loaded implant was 97.0%. The average bone resorption were 0.22 mm at 4-6 months after surgery, bone increase of 0.15 mm were found at 6-12 month, and bone increase up to 0.16 mm at 12-46 months. The gingival papilla index was 2.68, while pink esthetic score was 12.58.</p><p><b>CONCLUSION</b>Immediate loaded implant is an effective repairing method for patients missing teeth and the esthetics effect is ideal.</p>
