Identification and Validation of Biomarkers in Chronic Rhinosinusitis With Nasal Polyps and Study of Their Associated Mechanisms

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Cell senescence (CS) and lipid metabolism (LM) disorders have been reported in chronic rhinosinusitis with nasal polyps (CRSwNP). However, the mechanism is still unclear. Methods Data were obtained from public databases; differential expression analysis and machine learning were performed to identify biomarkers and to understand the

Vessel‐associated microglia are differentially activated and distributed in relation to systemic infection and Alzheimer's disease

Brain Pathology, EarlyView.
This post‐mortem study revealed an increased density of vessel‐associated microglia (VAM) in the temporal lobe in systemic infection and Alzheimer's disease. VAM density was related to brain cytokine levels and markers of cerebrovascular dysfunction and BBB leakage indicating that activated VAM contributes to neurovascular injury in Alzheimer's disease.

Endothelial Netrin‐4 regulates oligodendrocyte precursor cell proliferation and differentiation via ET‐1 signaling in preterm white matter injury

Brain Pathology, EarlyView.
Our findings show early increased Netrin‐4 in mice with PWMI boosts angiogenesis and OPCs proliferation. Later, high levels hinder OPCs differentiation into mature cells, impairing myelination. It may act by stimulating ET‐1 secretion. Abstract Perinatal hypoxia–ischemia is a leading cause of preterm white matter injury (PWMI), yet mechanisms ...

Amyloid‐β aggregates induce vasculopathy via ferroptosis in brain endothelial cells

Brain Pathology, EarlyView.
Blood–brain barrier (BBB) disruption is evident in brains with amyloidopathy. In this study, we demonstrate that amyloid β (Aβ) drives abnormal lipid metabolism and lipid droplet formation in brain endothelial cells, leading to lipid peroxidation and ferroptosis.

Optic nerve sheath meningioma exhibits neural niche‐associated transcriptomic features and rare copy number variation‐linked evolution

Brain Pathology, EarlyView.
Optic nerve sheath meningiomas are typically NF2‐intact with few copy number alterations and are generally clinically indolent. Rare aggressive recurrences are associated with progressive accumulation of copy number variations, including CDKN2A/B homozygous deletion, 1q gain, and 14q loss.

The relationship between the cannabinoids and cardiac remodelling: A comprehensive review of pivotal mechanisms and emerging evidence

British Journal of Pharmacology, EarlyView.
Cardiac remodelling and fibrosis after myocardial infarction or during chronic diseases, such as arterial and pulmonary hypertension or diabetes mellitus, continue to be the more important prognostic factors in determining survival, and so the search for effective anti‐fibrotic interventions is an important target for research and therapy in cardiology.
