Finite element analysis of wedge and biconcave deformity in four different height restoration after augmentation of osteoporotic vertebral compression fractures.

Purpose: Biomechanical comparison of wedge and biconcave deformity of different height restoration after augmentation of osteoporotic vertebral compression fractures was analyzed by three-dimensional finite element analysis (FEA).

Methods: Three-dimensional finite element model (FEM) of T11-L2 segment was constructed from CT scan of elderly osteoporosis patient. The von Mises stresses of vertebrae, intervertebral disc, facet joints, displacement, and range of motion (ROM) of wedge and biconcave deformity were compared at four different heights (Genant 0-3 grade) after T12 vertebral augmentation.

MicroRNA-628-5p inhibits cell proliferation in glioma by targeting DDX59.

Recent study has reported that microRNA-628-5p (miR-628-5p) is involved in the development of epithelial ovarian cancer; however, the mechanisms of miR-628-5p in glioma remain unclear. In this study, we explored the potential biological roles of miR-628-5p in glioma. First, we found that miR-628-5p was decreased in the tissues and cells (U87 and T98) of glioma.

Pouch Roux-en-Y vs No Pouch Roux-en-Y following total gastrectomy: a meta-analysis based on 12 studies.

After a total resection of the stomach, the continuity of the gastrointestinal tract can be restored either by Roux-en-Y esophagojejunostomy with or without a pouch. There is still no consensus on the best reconstruction technique. The aim of this report was to derive a more precise estimation of Roux-en-Y esophagojejunostomy with a pouch compared with Roux-en-Y esophagojejunostomy without a pouch.
