pediatric mandibular fractures have been successfully managed in various ways. the use of a lingual splint is an option. this article presents a 4-year old boy who was treated by an alternative conservative method with a combination of an arch bar plus a lingual splint, circum-mandibular wiring and imf for the reduction, stabilization and fixation of a severely displaced bilateral man dibular b...

A method for kinematics modeling of a six-wheel Rocker-Bogie mobile robot is described in detail. The forward kinematics is derived by using wheel Jacobian matrices in conjunction with wheel-ground contact angle estimation. Te inverse kinematics is to obtain the wheel velocities and steering angles from the desired forward velocity and turning rate of the robot. Traction Control also developed ...

The major facilitator superfamily represents the largest group of secondary membrane transporters in the cell. Here we report the 3.3 angstrom resolution structure of a member of this superfamily, GlpT, which transports glycerol-3-phosphate into the cytoplasm and inorganic phosphate into the periplasm. The amino- and carboxyl-terminal halves of the protein exhibit a pseudo two-fold symmetry. Cl...

Some functions of walking are adversely affected in prosthesis users because of reduced or absent ankle motion. However, combining a prosthetic ankle unit with a particular prosthetic foot could have unanticipated consequences. This study investigated the effect of prosthetic ankle units on the gait of persons with bilateral transtibial amputations. Subjects were tested while walking with and w...

Aiming at the complexity of dynamic model EMA pitching mechanism and feasibility simplification, this paper discusses influence rocker pushrod on characteristics effectively simplifies basis ensuring accuracy. Firstly, a simplified is established based Lagrange equation, equivalent inertia, force arm. Then, in pitch range, inertia arm are converted into load respectively, error compensation est...

drought stress is one of the serious problems that restricted agronomic plant production worldwide. inmolecular level, the harmful effect of drought stress is mostly caused by producing of large amount ofreactive oxygen species (ros). catalase and metallothionein genes have a crucial role to mope the hydrogenperoxide (h2o2) resulting reducing oxidative damage. in this research the gene expressi...

A plethora of cell biological processes involve modulations of cellular membranes. By using extended lipid-binding interfaces, some proteins have the power to shape membranes by attaching to them. Among such membrane shapers, the superfamily of Bin-Amphiphysin-Rvs (BAR) domain proteins has recently taken center stage. Extensive structural work on BAR domains has revealed a common curved fold th...

Members of the Bin/amphiphysin/Rvs (BAR) domain protein superfamily are involved in membrane remodeling in various cellular pathways ranging from endocytic vesicle and T-tubule formation to cell migration and neuromorphogenesis. Membrane curvature induction and stabilization are encoded within the BAR or Fer-CIP4 homology-BAR (F-BAR) domains, alpha-helical coiled coils that dimerize into membra...
