The prolactin/vasoinhibin axis defines an endocrine system, in which prolactin (PRL) and vasoinhibins regulate blood vessel growth and function, the secretion of other hormones, inflammatory and immune processes, coagulation, and behavior. The core element of the PRL/vasoinhibin axis is the generation of vasoinhibins, which consists in the proteolytic cleavage of their precursor molecule PRL. V...

The anatomical distribution of sensory-evoked activity recorded from the hippocampal long-axis can shift depending on prior experience. In accordance with Marr's computational model of hippocampal function, CA3 NMDA receptors have been hypothesized to mediate this experience-dependent shift in hippocampal activity. Here we tested this hypothesis by investigating genetically-modified mice in whi...

This study investigates if atlanto-occipital fusion affects the size and geometrical configuration of the articular facets of the atlanto-axial joint. Morphometric analysis was performed on the male adult skull, the occipital bone of which is assimilated with the first cervical vertebrae (the atlas). The perimeter, Feret's diameter, surface area, and circularity of the inferior articular fa-cet...

The subiculum is a pivotal but under-investigated structure positioned between the hippocampus proper and entorhinal and other cortices, as well as a range of subcortical structures. The subiculum has a range of electrophysiological and functional properties which are quite distinct from its input areas; given the widespread set of cortical and subcortical areas with which it interacts, it is a...

While the hippocampus has been classically studied for its role in learning and memory, there is significant support for a role of the HPC in regulating emotional behavior. Emerging research suggests these functions may be segregated along the dorsoventral axis of the HPC. In addition to this regional heterogeneity, within the HPC, the dentate gyrus is one of two areas in the adult brain where ...

The noninvasive evaluation of the cardiac function presents a great interest for the diagnosis of cardiovascular diseases. Cardiac tagged MRI allows the measurement of anatomical and functional myocardial parameters. This protocol generates a dark grid which is deformed with the myocardium. Tracking the grid allows the displacement estimation in the myocardium. The work described in this paper ...

purpose : to determine the association between astigmatism and spherical refractive error in a clinical population methods : in this cross-sectional study, 2,000 patients who presented to our optometry clinic were enrolled. all were tested for objective refraction with a nidek ar-310a auto refractometer, and non-cycloplegic refraction. for those under 15 years of age, cycloplegic refraction was...

OBJECTIVE With the advancement of 3D modeling techniques and visualization devices, augmented reality (AR)–based navigation (AR navigation) is being developed actively. The authors a pilot model their newly inside-out tracking AR system. METHODS technique was based on visual inertial odometry (VIO) algorithm. Quick Response (QR) marker created used for image feature–detection Inside-out works t...

Abstract Objectives 3D preoperative planning of lower limb osteotomies has become increasingly important in light modern surgical technologies. However, models are usually reconstructed from Computed Tomography data acquired a non-weight-bearing posture and thus neglecting the positional variations introduced by weight-bearing. We developed registration pipeline that allows for subsequent asses...

Introdouction: An exact knowledge of the anatomical variations of the paranasal sinuses (PNS) is critical for surgeons performing endoscopic sinus surgery and for radiologists involved in making preoperative evaluations. An important aspect is the determination of correlation between the anatomical variations of PNS and the presence of chronic rhinosinusitis (CR). Cone-beam computed tomograph...
