Short- and long-term effects of 56Fe irradiation on cognition and hippocampal DNA methylation and gene expression. [PDF]

, 2016
BackgroundAstronauts are exposed to 56Fe ions that may pose a significant health hazard during and following prolonged missions in deep space. We showed previously that object recognition requiring the hippocampus, a structure critical for cognitive ...

The Role of Magnetic Resonance Spectroscopy (MRS), Diffusion‐Tensor‐Imaging (DTI) and Structural MRI in the Alzheimer's Disease and Mild Cognitive Impairment Diagnosis: A Review

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Alzheimer's disease (AD) is one of the most common neurological disorders affecting older adults, with approximately 7.2 million cases only in the United States. This number is projected to increase to 13.8 million in the United States by 2060, leading to increased expenditures for healthcare, long‐term care and hospice services. Consequently,

Exploring adult hippocampal neurogenesis using optogenetics [PDF]

, 2018
In the 1980s, it was widely accepted that new neurons are continuously generated in the dentate gyrus of the mammalian hippocampus. Since its acceptance, researchers have employed various techniques and behavioral paradigms to study the proliferation ...

Deep learning cone‐beam computed tomography image segmentation for the 3D visualization of mandibular infraosseous periodontal defects

Journal of Periodontology, EarlyView.
Abstract Background The accurate assessment of infraosseous periodontal defects is crucial for effective diagnosis and treatment planning. Cone‐beam computed tomography (CBCT) enables detailed imaging of these defects; however, to leverage their full potential, CBCT images must be reconstructed in 3 dimensions (3D).

Perampanel Blocks Transsynaptic α‐Synuclein Propagation and Neurodegeneration in a Mouse Model of Lewy Body Disease

Movement Disorders, EarlyView.
Abstract Background Transsynaptic α‐synuclein propagation plays a crucial role in the progression of Lewy body disease. We previously demonstrated that an α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid receptor antagonist, perampanel, blocks neuronal uptake of α‐synuclein preformed fibrils (PFFs) in an activity‐dependent manner.

Female rat hippocampal cell density after conditioned place preference [PDF]

, 2014
The hippocampus is important for learning tasks, such as conditioned place preference (CPP), which is widely used as a model for studying the reinforcing effects of drugs with dependence liability.

Patient‐Reported Feedback Suggests an Alternative Sweet Spot for Deep Brain Stimulation Programming in Essential Tremor

Movement Disorders, EarlyView.
(1) To sample subjective patient rating using the Visual Analogue Scale (VAS), random stimulation parameters were presented to the study subjects. (2) Next, corresponding volumes of tissue activated (VTA) were generated and paired with VAS values.

Increased expression of aromatase after focal cerebral ischemia: Relevance to neuroprotection and functional recovery

Neuroprotection, EarlyView.
Abstract Aim Aromatase is the key enzyme in the biosynthesis of 17β‐estradiol, the most potent estrogen, which has pleiotropic neuroprotective properties. Aromatase levels increase in the brain after stroke, and its gene variants increase susceptibility to stroke. This study aims to determine whether aromatase overexpression improves stroke outcome and

Stem cell–mediated neuroplasticity and psychological recovery in cancer survivors: Mechanisms, evidence, and translational challenges

Precision Medical Sciences, EarlyView.
Cancer therapies can trigger neuroinflammation and disrupted neuroplasticity, contributing to cognitive impairment and psychological distress in survivors. Stem cells (NSCs/MSCs) and their extracellular vesicles may restore neural niches via trophic support, immunomodulation, synaptic remodeling, and vascular repair, but require rigorous safety, dosing,
