Article Abstract

Curcumin can reduce the production of brain inflammatory mediators and symptoms of brain diseases. However, a large amount of free curcumin needs to be administered to achieve an effective level in the brain because of its poor water-solubility. Fucoidan and chitosan were reported to respectively target P-selectin and acidic microenvironment expressed by pathologically inflammatory cells/tissues. Herein, the self-assembly of chitosan and fucoidan which could encapsulate curcumin was developed to form the multi-stimuli-responsive nanocarriers, and their pathological pH- and P-selectin-responsive aspects were characterized. Through intranasal delivery to the brain, these curcumin-containing chitosan/fucoidan nanocarriers with dual pH-/P-selectin-targeting properties to the brain lesions improved drug delivery, distribution, and accumulation in the inflammatory brain lesions as evidenced by an augmented inhibitory effect against brain inflammation. This promising multifunctional nanocarrier with a novel drug-delivery route should allow potential clinical biomedical uses by neurosurgeon in the future.

Evidence indicates that transposable elements (TEs) can contribute to the evolution of new traits, with some TEs acting as deleterious elements while others are repurposed for beneficial roles in evolution. In mammals, some KRAB-ZNF proteins can serve as a key defense mechanism to repress TEs, offering genomic protection. Notably, the family of KRAB-ZNF genes evolves rapidly and exhibits diverse expression patterns in primate brains, where some TEs, including autonomous LINE-1 and non-autonomous Alu and SVA elements, remain mobile.

IntroductionVenous sinus stenting (VSS) is an effective, less invasive alternative to ventriculoperitoneal shunting (VPS) for idiopathic intracranial hypertension (IIH). While efficacy is comparable, with some evidence favoring VSS for headache control, perioperative costs remain under-characterized due to reliance on reimbursement rates rather than actual expenditures.ObjectiveTo compare the perioperative cost of elective VSS and VPS for IIH, including outpatient workup and follow-up costs, using detailed institutional cost data.

Importance: Behavioral variant frontotemporal dementia (bvFTD), the most common subtype of FTD, is a leading form of early-onset dementia worldwide. Accurate and timely diagnosis of bvFTD is frequently delayed due to symptoms overlapping with common psychiatric disorders, and interest has increased in identifying biomarkers that may aid in differentiating bvFTD from psychiatric disorders.

Objective: To summarize and critically review studies examining whether neurofilament light chain (NfL) in cerebrospinal fluid (CSF) or blood is a viable aid in the differential diagnosis of bvFTD vs psychiatric disorders.

Importance: Cannabis is the most commonly used illicit drug, with 10% to 30% of regular users developing cannabis use disorder (CUD), a condition linked to altered hippocampal integrity. Evidence suggests high-intensity interval training (HIIT) enhances hippocampal structure and function, with this form of physical exercise potentially mitigating CUD-related cognitive and mental health impairments.

Objective: To determine the impact of a 12-week HIIT intervention on hippocampal integrity (ie, structure, connectivity, biochemistry) compared with 12 weeks of strength and resistance (SR) training in CUD.
