Mapping Anatomical Boundaries from Histology to Antemortem MRI to Inform Automatic Segmentation of Medial Temporal Lobe Subregions [PDF]

Alzheimers Dement
Abstract Background The medial temporal lobe (MTL) is the epicenter of both primary and concomitant molecular pathologies in Alzheimer’s disease (AD). The intricate anatomy of the MTL has been the subject of extensive study over the past two centuries.

Associations between Quantitative Neuronal Loss Measures and Postmortem MRI Atrophy Measures in the Human Medial Temporal Lobe in AD and LATE [PDF]

Alzheimers Dement
Abstract Background Medial temporal lobe (MTL) atrophy measured on MRI is a sensitive biomarker of AD‐linked neurodegeneration but is not specific to AD. LATE is a common AD co‐pathology that is challenging to distinguish from AD based on available validated biomarkers. LATE and AD are both associated with hippocampus and entorhinal cortex atrophy, but

Neuropeptides in the developing human hippocampus under hypoxic-ischemic conditions. [PDF]

J Anat, 2021
Hypoxia‐ischemia during the perinatal period could damage the hippocampal interneuron populations which might lead to the appearance of different problems during subsequent development. Interneurons containing Somatostatin and Neuropeptide Y located in the hippocampal ammonic fields are affected differently, although there is a global reduction after ...

Developing an Anatomically Valid Segmentation Protocol for Anterior Regions of the Medial Temporal Lobe for Neurodegenerative Diseases. [PDF]

Hippocampus
ABSTRACT The anterior portion of the medial temporal lobe (MTL) is one of the first regions targeted by pathology in sporadic Alzheimer's disease (AD) and limbic‐predominant age‐related TDP‐43 encephalopathy (LATE) indicating a potential for metrics from this region to serve as imaging biomarkers.

Developing an anatomically valid segmentation protocol for anterior regions of the medial temporal lobe [PDF]

Alzheimers Dement
Abstract Background The anterior portion of the MTL is one of the first regions targeted by pathology in sporadic Alzheimer’s disease (AD) indicating the potential for imaging metrics from this region to serve as valuable imaging biomarkers. However, most existing automated approaches for MTL segmentation do not incorporate anterior MTL subregions, and

Prophylactic Zinc Administration Combined with Swimming Exercise Prevents Cognitive-Emotional Disturbances and Tissue Injury following a Transient Hypoxic-Ischemic Insult in the Rat. [PDF]

Behav Neurol, 2022
Exercise performance and zinc administration individually yield a protective effect on various neurodegenerative models, including ischemic brain injury. Therefore, this work was aimed at evaluating the combined effect of subacute prophylactic zinc administration and swimming exercise in a transient cerebral ischemia model.
