Direct Anterior Approach: Risk Factor for Early Femoral Failure of Cementless Total Hip Arthroplasty: A Multicenter Study.

Background: The direct anterior approach for total hip arthroplasty (THA) is marketed with claims of superiority over other approaches. Femoral exposure can be technically challenging and potentially lead to early failure. We examined whether surgical approach is associated with early THA failure.

Pyramidal cells in prefrontal cortex of primates: marked differences in neuronal structure among species.

The most ubiquitous neuron in the cerebral cortex, the pyramidal cell, is characterized by markedly different dendritic structure among different cortical areas. The complex pyramidal cell phenotype in granular prefrontal cortex (gPFC) of higher primates endows specific biophysical properties and patterns of connectivity, which differ from those in other cortical regions. However, within the gPFC, data have been sampled from only a select few cortical areas.

Assessment of quality of life and participation within an outpatient rehabilitation setting.

Purpose: To evaluate the use of quality of life and participation measures in routine rehabilitation practice, determine the relationship between two scales and investigate their ability to evaluate change in a general outpatient population over a time of rehabilitation.

Methods: This cohort study consisted of 55 patients admitted consecutively to an outpatient rehabilitation centre. All participants completed the WHOQOL-BREF and the London Handicap Scale (LHS) at admission and discharge.

Specialization of pyramidal cell structure in the visual areas V1, V2 and V3 of the South American rodent, Dasyprocta primnolopha.

Marked phenotypic variation has been reported in pyramidal cells in the primate cerebral cortex. These extent and systematic nature of these specializations suggest that they are important for specialized aspects of cortical processing. However, it remains unknown as to whether regional variations in the pyramidal cell phenotype are unique to primates or if they are widespread amongst mammalian species.
