Computational study of the dimerization of glyphosate: mechanism and effect of solvent.

A computational study on the structure and stability of different series of glyphosate (Glyph) dimers comprising nonionized (N) and zwitterionic structures (Z) for neutral monomers, followed by an analysis of energetics of Glyph dimerization process have been performed by means of quantum chemical calculations in different media. Optimized geometries for energy minima, as well as relative potential and free energies of the possible various conformers of each series of Glyph dimer were computed as a function of the medium at B3LYP-D3/6-311++G(2d,2p) level. The solvation model based on density (SMD) is employed for all solution phase computations.

Interest of longitudinal patellar tunnels in reconstructing chronic patellar tendon rupture with semitendinosus autograft: A case report.

Treatment of chronic patellar tendon ruptures represents a real challenge for orthopaedic surgeons. The superior patellar migration and the pathological aspect of the tendon are the two conditions that aggravate the situation. Several reconstruction methods have been described in the literature.

Clinical and radiographic outcomes after paediatric supracondylar humeral fractures treated with combined intramedullary and lateral wire fixation: our experience in fifty-one cases.

Purpose: Displaced supracondylar humerus fractures in children are known for their high rate of complications and require urgent surgical treatment. Basically, there are two methods of fracture fixation: the lateral pin technique and the crossed pin technique. However, the best technique remains debated.

Intrapelvic migration of the lag screw in intramedullary nailing after intertrochanteric fracture fixation: A case report.

The expected number of hip fractures worldwide will rise from 1.7 million in 1990, to 6.3 million in 2050.
