Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Case Reprot of Giant Cell Tumor on Femur Recurring 16 Years after Cement Packing Method.

Orthopedics & Traumatology, 2002
We report a giant cell tumor of the femur recurring 16 years after the cement packing method. A 59-year-old man was treated surgically with curettage, bone grafting and cement packing method for a giant cell tumor on one of his femurs in 1985. Part of plain radiograph indicated radiolucent area on the subchondral bone at an early stage, but the size of

An algorithm for seizure detection in rodents

Epilepsia Open, EarlyView.
Abstract Objective Epilepsy animal research often relies on long‐term intracranial electroencephalographic (iEEG) recordings. Here, we describe an artificial neural network (ANN) algorithm for automatic detection of seizures. Methods The algorithm was trained on iEEG recordings of three mouse models of chronic epilepsy: (1) the pilocarpine model of ...
