In this study, we introduced a length-normalized parameterization method to establish anatomical correspondence of white matter fiber tracts across subjects and applied this method to investigate the presence of abnormal diffusion along the pyramidal tract (PYT) of relapsing neuromyelitis optica (RNMO) patients without visible brain lesions. In this approach, the part of the PYT between the low...

Twelve years ago we reported an electrical impedance baseline study related to age, sex and body locations. The results showed significant differences between different anatomical locations and ages. In this study, the same participants were recalled to explore how the skin had evolved at the individual level over time. A total of 50 subjects, divided into an older and a younger group, were rec...

Multiple sclerosis (MS) damages central white matter pathways which has considerable impact on disease-related disability. To identify disease-related alterations in anatomical connectivity, 34 patients (19 with relapsing remitting MS (RR-MS), 15 with secondary progressive MS (SP-MS) and 20 healthy subjects underwent diffusion magnetic resonance imaging (dMRI) of the brain. Based on the dMRI, a...

The way in which normal variations in human neuroanatomy relate to brain function remains largely uninvestigated. This study addresses the question by relating anatomical measurements of Heschl's gyrus (HG), the structure containing human primary auditory cortex, to how this region processes temporal and spectral acoustic information. In this study, subjects' right and left HG were identified a...

Using voxel-based morphometry, we measured the cerebral anatomical asymmetries in a sample of 56 young right-handed males and then compared voxelwise asymmetry indices of these subjects to those of 56 young left-handed males. In the right-handed, the clusters of grey matter asymmetry corresponding to the leftward occipital petalia and planum temporale asymmetries were retrieved. Strong rightwar...

Accurate measurement of the lower limb anatomy is clinically important not only for applications such as implants selection and fracture management, but also for planning the corrective osteotomy operations in case of having excessive deformities [1]. The 3D reconstructed anatomical models, based on CT or MRI, provide an effective tool for analysing the anatomy of long bones [2]. However, there...

The extraction of cardiac borders, particularly, the ones related to the left ventricle (LV), is an important goal to estimate some indices of great clinical value, such as, the thickness of the wall, ejection fraction, and regional wall motion, as the most used to assess the LV function. The accuracy of those indices depends on the correct LV boundary extraction. In this work, two LV segmentat...

OBJECTIVE To describe the role of routine radiographic examination of clinically healthy completely edentulous jaws prior to fabrication of the first set of complete dentures. DESIGN Cross-sectional retrospective descriptive study. SETTINGS The departments of Conservative and Prosthetic Dentistry, and Oral and Maxillofacial Surgery, Oral Medicine/Oral Pathology, Dental Maxillofacial Radiolo...

In all comparative analyses, humans always fall on the borderline between obligate monogamy and polygamy. Here, we use behavioural indices (sociosexuality) and anatomical indices (prenatal testosterone exposure indexed by 2D : 4D digit ratio) from three human populations to show that this may be because there are two distinct phenotypes in both sexes. While males are more promiscuous and displa...
