MRI Epicenters Differentiate Spatiotemporal Patterns of Neurodegeneration in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
A connectivity‐based MRI epicenter model identifies two Parkinson's disease subtypes: subtype 1 with infratentorial‐dominant epicenters, severe motor symptoms, and rapid progression; and subtype 2 with supratentorial‐dominant epicenters with mild progression.

Parabiosis, Assembloids, Organoids (PAO)

open access: yesAdvanced Science, EarlyView.
This review evaluates parabiosis, organoids, and assembloids as complementary disease models spanning systemic, organ, and multi‐organ levels. It highlights their construction strategies, applications, and current limitations, while emphasizing their integration with frontier technologies such as artificial intelligence, organ‐on‐a‐chip, CRISPR, and ...

Sex Differences in Associations of Lewy Body Disease with Alzheimer's Disease and Cognitive Decline

open access: yesAnnals of Neurology, EarlyView.
Objective To investigate how sex and age at menopause influence the interplay between Alzheimer's disease (AD) and Lewy body disease (LBD) neuropathologies, and their associations with cognitive decline. Methods We analyzed data from: (1) three Rush Alzheimer's Disease Center cohorts (i.e., the Religious Orders Study, Rush Memory and Aging Project, and

Effect of certain psychopharmacological preparations on adaptation under stress conditions [PDF]

open access: yes
Experiments staged on rats demonstrated that the formation of pathological states caused by stress and accompanied by the development of ulcerative lesion of the gastric mucosa are associated with the degree of the catecholamines level drop in the ...

Disease Progression in Multiple System Atrophy: The ASPIRE Multi‐Modal Biomarker Study

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to characterize changes in candidate biomarkers in early multiple system atrophy (MSA) and identify baseline predictors of faster progression. Methods This 1‐year, multicenter, prospective study assessed clinical, neuroimaging (3T‐magnetic resonance imaging [MRI], dopamine transporter single‐photon emission ...

Increased Expression and Redistribution of the Antiapoptotic Molecule Bcl-xL in Parkinson's Disease

open access: yesNeurobiology of Disease, 2002
In the present study, we tried to clarify the potentially protective role of Bcl-xL, an anti-apoptotic member of the Bcl-2 family of proteins, in Parkinson's disease (PD).

Reward-aversion analysis of rat mesencephalon

open access: yesNeuroscience Letters, 1977
Abstract The topographical distribution of reward and aversion effects to intracranial stimulation (ICS) through monopolar electrodes was investigated at 61 sites in the rat mesencephalon. In order to minimize interpretive difficulties all rats were tested with identical ICS frequency (50 Hz), pulse width (200 μsec) and current strength (150 μA).
