3-N-Butylphthalide alleviate Aβ-induced cellular senescence through the CDK2-pRB1-Caspase3 axis.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the accumulation of amyloid-beta (Aβ) and leading to cellular senescence and cognitive deficits. Cellular senescence contributes significantly to the pathogenesis of AD through the senescence-associated secretory phenotype (SASP), exacerbating Aβ deposition. This study investigates the protective effects of 3-N-Butylphthalide (NBP), a compound derived from Apium graveolens Linn (Chinese celery), on Aβ-induced cellular senescence in U87 cells.

Comprehension of acoustically degraded emotional prosody in Alzheimer's disease and primary progressive aphasia.

Previous research suggests that emotional prosody perception is impaired in neurodegenerative diseases like Alzheimer's disease (AD) and primary progressive aphasia (PPA). However, no previous research has investigated emotional prosody perception in these diseases under non-ideal listening conditions. We recruited 18 patients with AD, and 31 with PPA (nine logopenic (lvPPA); 11 nonfluent/agrammatic (nfvPPA) and 11 semantic (svPPA)), together with 24 healthy age-matched individuals.

Cognitive and neurodegenerative trajectories of subjective cognitive decline according to baseline biomarkers: Results of the CoSCo study.

Introduction: Alzheimer's disease (AD) is now diagnosed biologically. Since subjective cognitive decline (SCD) may indicate preclinical AD, assessing AD-biomarkers is crucial. We investigated cognitive and neurodegenerative trajectories in SCD over 24 months based on biomarker positivity, and evaluated the predictive value of plasma biomarkers.

Disrupted brain networks underlying high-fidelity memory retrieval in subjective cognitive decline: A task-based fMRI study.

Introduction: Subjective cognitive decline (SCD) is linked to memory complaints and disruptions in certain brain regions identified by molecular imaging and resting-state functional magnetic resonance imaging studies. However, it remains unclear how these regions interact to contribute to both subjective and potential objective memory issues in SCD.

Methods: To address this gap, task-based imaging studies are essential.

Plasma phosphorylated tau and neuropsychiatric symptoms in dementia with Lewy bodies.

Introduction: Neuropsychiatric symptoms (NPSs) are common in dementia with Lewy bodies (DLB) but their neurobiological mechanisms are poorly understood.

Methods: NPSs and cognition were assessed annually in participants (DLB n = 222; Alzheimer's disease [AD] n = 125) from the European DLB (E-DLB) Consortium, and plasma phosphorylated tau-181 (p-tau181) and p-tau231 concentrations were measured at baseline.

Results: Hallucinations, delusions, and depression were more common in DLB than in AD and, in a subgroup with longitudinal follow-up, persistent hallucinations and NPSs were associated with lower p-tau181 and p-tau231 in DLB.

Treatment for peripheral nerve injury: a protocol for a systematic review and Bayesian network meta-analysis.

Introduction: Available therapies for peripheral nerve injury (PNI) include surgical and non-surgical treatments. Surgical treatment includes neurorrhaphy, grafting (allografts and autografts) and tissue-engineered grafting (artificial nerve guide conduits), while non-surgical treatment methods include electrical stimulation, magnetic stimulation, laser phototherapy and administration of nerve growth factors. However, the treatments currently available to best manage the different PNI manifestations remain undetermined.

Early neurological deterioration in acute ischemic minor stroke patients with large vessel occlusion following intravenous thrombolysis.

Objective: Early identification of risk factors associated with early neurological deterioration (END) in patients with acute minor stroke and large vessel occlusion (LVO) receiving intravenous thrombolysis (IVT) could assist in formulating treatment decisions.

Methods: Consecutive patients with acute minor stroke and LVO were extracted from a single-center prospective database spanning January 2020 to December 2023. END was defined as an increase of ≥ 4 points in the National Institutes of Health Stroke Scale (NIHSS) score from baseline, or ≥ 2 points in any single NIHSS item, within 24 hours of the IVT.

Molecular biomarkers associated with TBI outcome in individuals of Black racial identity or African ancestry: a narrative review.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide and a major global health concern. In the United States (US), individuals of Black or African American racial identity experience disproportionately higher rates of TBI and suffer from worse post-injury outcomes. Contemporary research agendas have largely overlooked or excluded Black populations, resulting in the continued marginalization of Black patient populations in TBI studies, thereby limiting the generalizability of ongoing research to patients in the US and around the world.
