Physiological studies suggest spatial representation gradients along the CA1 proximodistal axis. To determine the underlying anatomical basis, we quantitatively mapped canonical and noncanonical inputs to excitatory neurons in dorsal hippocampal CA1 along the proximal-distal axis in mice of both sexes using monosynaptic rabies tracing. Our quantitative analyses show comparable strength of subic...

The most commonly used proximal femoral fracture measures for predicting femur neck and intratrochanteric fractures are femoral axis length (FAL), hip axis length (HAL) and the derived Q angle measure (neck-shaft angle). The listed measures only consider the relationship between the diaphysis and the femoral neck but not also between the femoral head and neck. These measures assume the femoral ...

    Background: The aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3D reconstructive CT scan imaging. Methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. Preoperatively, all the patients underwent a CT scan according to a standard ...

Bragg diffraction imaging enables the quality of synthetic single-crystal diamond substrates and their overgrown, mostly doped, diamond layers to be characterized. This is very important for improving diamond-based devices produced for X-ray optics and power electronics applications. The usual first step for this characterization is white-beam X-ray diffraction topography, which is a simple and...

The hypothalamic-pituitary axis is recognized to an increasing extent as a physiological unit which influences and is influenced by endocrine and autonomic function. Anatomically, however, a clear distinction is to be drawn, with regard to both cellular and vascular anatomy, betweenthe neural (hypothalamus and neurohypophysis) and the glandular epithelial (pars distalis) components of the axis....

Major morphological transformations, such as the evolution of elongate body shape in vertebrates, punctuate evolutionary history. A fundamental step in understanding the processes that give rise to such transformations is identification of the underlying anatomical changes. But as we demonstrate in this study, important insights can also be gained by comparing these changes to those that occur ...
