Epigenetics across the human lifespan
Epigenetics has the potential to explain various biological phenomena that have heretofore defied complete explication. This review describes the various types of endogenous human developmental milestones such as birth, puberty, and menopause, as well as the diverse exogenous environmental factors that influence human health, in a chronological epigenetic context. We describe the entire course ...

متن کاملVoxel-based relaxometry for cases of an unresolved epilepsy diagnosis.
PURPOSE Voxel-based relaxometry (VBR) is a technique in which a voxel-level statistical comparison of quantitative MR T2 maps is performed to identify regions with significantly elevated T2 relaxation time. Our objective was to assess the performance of single-subject VBR at 3T as a diagnostic tool for patients whose diagnosis of epilepsy or seizure focus location is uncertain. METHODS Fifty-...
متن کاملAssessing the Effect of Age on Voxel-Based Relaxometry of Epileptic Patients
INTRODUCTION T2 weighted MR imaging can be helpful in locating epileptogenic lesions since a correlation has been found between the presence of epileptogenic tissue and elevated T2 relaxation time. T2 relaxometry (quantitative assessment of T2 relaxation time) is a sensitive tool for identifying T2 abnormalities. T2 Voxel Based Relaxometry (VBR) is a technique which performs a voxel-level stati...
متن کاملEvolution of hippocampal shapes across the human lifespan.
Aberrant hippocampal morphology plays an important role in the pathophysiology of aging. Volumetric analysis of the hippocampus has been performed in aging studies; however, the shape morphometry--which is potentially more informative in terms of related cognition--has yet to be examined. In this paper, we employed an advanced brain mapping technique, large deformation diffeomorphic metric mapp...
