conclusions in this case series study, the fixation of different types of tibial plateau fractures with 3.5 mm simple non-locking and non-precontoured plates was associated with acceptable clinical, functional, and radiographic outcomes. based on the advantages and costs of these plates, the authors recommend using 3.5 mm simple plates for different types of tibial plateau fractures. results th...

there have been a number of developments in screw design and implantation techniques over recent years, including proposal of an alternative trajectory entitled as cortical bone trajectory (cbt). cortical bone trajectory has been investigated in recent medical treatments as an alternative for screw fixation aimed at increasing purchase of pedicle screws in higher density bone. cbt screw inserti...

introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...

We describe the courses of treatment for epilepsies in two patients with semilobar type holoprosencephaly (HPE); a 5-year-old girl and 30-year-old man. Seizure semiology included eye fixation, upward or lateral gaze, horizontal vertical nystagmus, eyelid flutter, grinning facial distortion, which frequently evolved to generalized tonic convulsions. In both patients, ictal electroencephalography...

the aim of this study is to compare three modes of femoral fixation, namely aperfix, rigidfix and endobutton, in anterior cruciate ligament (acl) reconstruction. 120 patients were randomly assigned to three groups, each consisting of 40 patients, and each group was treated by one of the above mentioned methods of femoral fixation. all patients were examined prior to and 24 months after surgery,...

background: central venous catheters (cvcs) are used not only as a tool to access to central venous system, but also for hemodynamic monitoring, parenteral nutrition, chemotherapy and hemodialysis. the use of cvcs is associated with some complications notably infections that are troublesome both to patient and physician. we conducted this study to examine catheter fixation with skin fold techni...

In Lebanon, potato occupies a surface of 14,800 ha corresponding to 17% of the irrigated land. The Bekaa valley is the largest production area in the country, with more than 67% of total potato production located on prime land. This crop is generally fertilized by soil application and irrigated by sprinklers with rare implementation of drip systems. Spring and summer potatoes depend entirely on...

A direct method called fixation is introduced for solving the general motion vision problem, arbitrary motion relative to an arbitrary environment. This method results in a linear constraint equation which explicitly expresses the rotational velocity in terms of the translational velocity. The combination of this constraint equation with the Brightness-Change Constraint Equation solves the gene...

Effects of fixation with glutaraldehyde (GA), glutaraldehyde-osmium tetroxide (GA-OsO(4)), and osmium tetroxide (OsO(4)) on ion and ATP content, cell volume, vital dye staining, and stability to mechanical and thermal stress were studied in Ehrlich ascites tumor cells (EATC). Among variables investigated were fixation time, fixative concentration, temperature, osmolality of the fixative agent a...

Abstract The increasing demand for agricultural products can be met by maximizing production potential and reducing crop losses caused common plant-parasitic nematodes. Chemical-based nematode management is a successful technique mitigating damage yield pests; however, inappropriate irresponsible application of synthetic pesticides has negative impacts on fauna, bioflora, natural enemies such a...
