Subsequently, they underwent decalcification and were stained for histologic analysis.
Results. There was no significant difference between groups at 6 weeks after operation. In the mu-CT results, however, tissue mineral content in the experimental group at 12 weeks after operation was 132.09 +/- 4.41 and that in the control group was 126.42 +/- 6.62 (P = .011). Tissue mineral density in the experimental group was 2,088.88 +/- 648.34, and that in the control group was 2,029.72 +/- 668.22 (P see more = .013). The results of the histomorphometric analysis were in accordance with the mu-CT results. The total new bone was 49.86 +/- 7.49% in the control group at
12 weeks after the operation and 59.83 +/- 10.92% in the experimental group (P = .021).
Conclusion. A combined application of Choukroun PRF with acid-digested silk fibroin showed more rapid bone healing than unfilled control. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010; 109: e33-e38)”
“Methods: Results of clinical data and find more contrast venography of 302 consecutive patients scheduled for first ICD implantation were analyzed.
Results: Prevalence
of upper vein obstruction was 6.6% (20/302 patients) in a typical patient population undergoing first ICD implantation. Age, left ventricular ejection fraction, underlying heart disease, prior open-heart surgery, or cardiopulmonary resuscitation were not predictors of obstruction. Patients with previous cardiac pacemaker implantation had a higher rate of obstruction,
though this was not statistically significant (20% vs 15.7%, P = 0.54). Persistent left vena cava was found in 0.7%.
Conclusion: There is no clinical parameter sufficient enough to predict upper extremity venous obstruction. Contrast venography may be considered in patients with previous pacemaker placement but should not be a routine diagnostic tool in unselected patients prior to first ICD-implantation procedure.

“P>Shoot branching is one of the major determinants of plant architecture. Polar auxin transport click here in stems is necessary for the control of bud outgrowth by a dominant apex. Here, we show that following decapitation in pea (Pisum sativum L.), the axillary buds establish directional auxin export by subcellular polarization of PIN auxin transporters. Apical auxin application on the decapitated stem prevents this PIN polarization and canalization of laterally applied auxin. These results support a model in which the apical and lateral auxin sources compete for primary channels of auxin transport in the stem to control the outgrowth of axillary buds.”
“Objective. This study aimed at elucidating the influence of insertion protocol and implant shoulder design on periimplant soft tissue healing.
Study design. One month after removal of all maxillary premolars in 12 minipigs, 4 implants were installed in each quadrant. According to implant shoulder design, 3 groups were established: 1) rough, 0.4 mm; 2) smooth, 3 mm; and 3) smooth, 0.
