Each type of oral mucosa is believed to develop through
discrete molecular mechanisms, which remain unclear. MicroRNAs (miRNAs) are 19 to 25nt non-coding small single-stranded RNAs that negatively regulate gene expression by binding target mRNAs. miRNAs are crucial for fine-tuning of molecular mechanisms. To investigate the role of miRNAs in oral mucosa development, we examined mice with mesenchymal (Wnt1Cre; Dicer(fl/fl)) conditional deletion of Dicer. Wnt1Cre; Dicer(fl/fl) mice showed trans-differentiation of lining mucosa into an epithelium with masticatory mucosa/skin-specific characteristics. Up-regulation of Fgf signaling was found in mutant lining mucosal epithelium that was accompanied by an increase in Fgf7 expression in mutant mesenchyme. Mesenchyme miRNAs thus have an indirect effect on lining Buparlisib ic50 mucosal epithelial cell growth/differentiation.”
“Background and Purpose: Laparoendoscopic single-site (LESS) surgery has been shown to be feasible in living donor nephrectomies (DNs).
Obesity is an established risk factor for perioperative morbidity. We sought to determine whether LESS-DN is safe and effective in the obese (body mass index [BMI] >= 30 kg/m(2)) population.
Patients and Methods: Between August 2009 and September 2010, 125 consecutive LESS-DN were performed; 32 patients were obese. This group FK506 cost was matched to 32 nonobese LESS-DN (BMI <30 kg/m(2)) patients, 32 obese conventional laparoscopic DN (obese E7080 solubility dmso LAP-DN) patients, and 32 nonobese LAP-DN patients. Comparison parameters included organ recovery time, operative time, estimated blood loss (EBL), warm ischemia time (WIT), incision length, complications, and recipient allograft function.
Results: Demographic data were similar between
the groups, except BMI (P > 0.0001). Organ recovery time, EBL, WIT, complications, and recipient allograft function were similar between the obese LESS-DN group and the other three groups (P > 0.05). Total operative time was longer in the obese LESS-DN compared with the nonobese LAP-DN (P < 0.0001); however, incision length was shorter in the obese LESS-DN group compared with either LAP group (P < 0.0001). Complete LESS-DN was successful in 62 (97%) cases (two obese donor cases were converted to hand-assisted laparoscopy).
Conclusions: Our results indicate that LESS-DN can be performed safely in obese donors without increased donor morbidity and similar recipient allograft outcomes compared with ideal-sized donors as well as with conventional LAP-DN patients.”
