Background: The aim of this study was to investigate the relationship between intracranial injury and serum tau protein levels in pediatric patients with minor head trauma (MHT).
Methods: We included 60 pediatric patients with MHT (Glasgow Coma Scale [GCS], 14-15) and 28 control patients. The patients were divided into 3 groups as follows: those without (group 1) and with (group 2) intracranial lesions shown on cranial computed tomography (CCT) and the control group (group 3).
Results: The mean serum tau protein level was 96.06 +/- 70.36 pg/mL in group 1, whereas it was 112.04 +/- 52.66 pg/mL in group 2, with no statistically significant difference between the groups (p = .160). The mean serum tau protein levels between the study groups (group 1 and group 2) and control (38.52 +/- 29.01) were statistically significant (P < .001 and P < .001, respectively). The GCS score and pathologic condition in CCT were only influential variables on tau protein levels.
Conclusions: We found that serum tau protein increased after MHT but did not distinguish between those with and those without intracranial lesions demonstrable on CCT.

Down syndrome (DS) is strongly associated with Alzheimer's disease (AD) due to APP overexpression, exhibiting Amyloid-β (Aβ) and Tau pathology similar to early-onset (EOAD) and late-onset AD (LOAD). We evaluated the Aβ plaque proteome of DS, EOAD, and LOAD using unbiased localized proteomics on post-mortem paraffin-embedded tissues from four cohorts (n = 20/group): DS (59.8 ± 4.

Introduction: Young-onset neurocognitive symptoms result from a heterogeneous group of neurological and psychiatric disorders which present a diagnostic challenge. To identify such factors, we analysed the Biomarkers in Younger-Onset Neurocognitive Disorders cohort, a study of individuals <65 years old presenting with neurocognitive symptoms for a diagnosis and who have undergone cognitive and biomarker analyses.
Methods: Sixty-five participants (median age at assessment of 56 years, 45% female) were recruited during their index presentation to the Royal Melbourne Hospital Neuropsychiatry Centre, a tertiary specialist service in Melbourne, Australia, and categorized as either early-onset Alzheimer's disease ( = 18), non-Alzheimer's disease neurodegeneration ( = 23) or primary psychiatric disorders ( = 24).

In vitro and animal studies have suggested that inoculation with herpes simplex virus 1 (HSV-1) can lead to amyloid deposits, hyperphosphorylation of tau, and/or neuronal loss. Here, we studied the association between HSV-1 and Alzheimer's disease biomarkers in humans. Our sample included 182 participants at risk of cognitive decline from the Multidomain Alzheimer Preventive Trial who had HSV-1 plasma serology and an amyloid PET scan.

Histone acetylation is the process by which histone acetyltransferases (HATs) add an acetyl group to the N-terminal lysine residues of histones, resulting in a more open chromatin structure. Histone acetylation tends to increase gene expression more than methylation does. In the central nervous system (CNS), histone acetylation is essential for controlling the expression of genes linked to cognition and learning.

Alzheimer's disease (AD) is an irreversible neurodegenerative disorder that poses a significant risk to human health and well-being. The high cost and invasiveness of neuroimaging and cerebrospinal fluid (CSF) analysis underscores the necessity for accessible early screening via blood samples. In this study, we developed an ultrasound-based strategy for emergent macroscopic that enhances the acoustic response enrichment of specific proteins by introducing functionalized microspheres.
