Xanthatin‐13‐(Pyrrolidine‐2‐Carboxylic Acid), a Sesquiterpene Lactone Isolated From Burdock Leaf, Attenuated Aβ25‐35 Toxicity and Memory Deficits in a Pharmacological Mouse Model of Alzheimer's Disease

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a severe form of dementia, which occurrence increases with age and lifestyle conditions. It is characterized by amyloid protein accumulation forming senile plaques, hyperphosphorylated tau protein forming neurofibrillary tangles, neuroinflammation, and oxidative stress, leading to synapse loss and cell death ...

Increased mRNA Expression for the α\u3csub\u3e1\u3c/sub\u3e Subunit of the GABA\u3csub\u3eA\u3c/sub\u3e Receptor Following Nitrous Oxide Exposure in Mice [PDF]

open access: yes, 2001
The mechanisms by which nitrous oxide (N2O) produces physical dependence and withdrawal seizures are not well understood, but both N2O and ethanol exert some of their effects via the GABAA receptor and several lines of evidence indicate that withdrawal ...

Neuropathologic findings and age‐related differences in Finnish pediatric medico‐legal autopsies

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Neuropathological examination plays a critical role in medico‐legal cause‐of‐death investigation, especially in determining the cause and manner of death in pediatric autopsies. Although a comprehensive neuropathological examination is recommended, limited data exists of the diagnostic yield of neuropathology consultations in such cases.

The CA3 “backprojection” to the dentate gyrus [PDF]

open access: yes, 2007
The hippocampus is typically described in the context of the trisynaptic circuit, a pathway that relays information from the perforant path to the dentate gyrus, dentate to area CA3, and CA3 to area CA1. Associated with this concept is the assumption that most hippocampal information processing occurs along the trisynaptic circuit.

Hippocampal subfield differences in people with and without recreational ketamine use: Insights from multi‐modal neuroimaging

open access: yesAddiction, EarlyView.
Abstract Background and aims Recreational ketamine use has increased globally and is associated with psychiatric and cognitive concerns. The hippocampus in preclinical models shows damage and working‐memory disruption with repeated dosing. However, whether specific hippocampal subregions may differ in people with chronic ketamine use remains unclear ...

Associations of cannabis use, tobacco use and co‐use with brain volume: A systematic review and meta‐analysis

open access: yesAddiction, EarlyView.
Abstract Background and aims Cannabis is the most widely used illicit drug worldwide and is often co‐used with tobacco, the leading cause of preventable death. Although cannabis and tobacco have distinct neurobiological actions, their associations with brain volumes are unclear.

Network structure determines patterns of network reorganization during adult neurogenesis [PDF]

open access: yes, 2009
New cells are generated throughout life and integrate into the hippocampus via the process of adult neurogenesis. Epileptogenic brain injury induces many structural changes in the hippocampus, including the death of interneurons and altered connectivity ...

Regulator of G protein signaling 6 mediates exercise-induced recovery of hippocampal neurogenesis, learning, and memory in a mouse model of Alzheimer’s disease

open access: yesNeural Regeneration Research
Hippocampal neuronal loss causes cognitive dysfunction in Alzheimer’s disease. Adult hippocampal neurogenesis is reduced in patients with Alzheimer’s disease.

Associations between TMEM106B C‐terminal fragment aggregation, age, and TDP‐43 or tau pathology

open access: yesBrain Pathology, EarlyView.
TMEM106B C‐terminal fragment (CTF) aggregation represents an age‐associated, common, diffuse phenomenon emerging after midlife with a weak association with TDP‐43 or tau pathology. These findings suggest that TMEM106B fibrillization may define a distinct axis of protein aggregation in the aging human brain. Abstract Transmembrane protein 106B (TMEM106B)

Human brain matters: Navigating the neuropathology of COVID‐19

open access: yesBrain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive
