In this work, we developed potential multifunctional agents to combat Alzheimer's disease. According to our strategy, fragments of tacrine and donepezil were merged in a unique hybrid structure. After successfully synthesizing the compounds, they were evaluated for their dual AChE/BuChE inhibitor potential and neuroprotector response using a glutamate-induced excitotoxicity model.

Even with recent advancements in surgery and multimodal adjuvant therapy, brain cancer treatment is still difficult. The blood-brain barrier and the potentially deadly medications' nonspecificity have made pharmacological treatment for brain cancer particularly ineffective. The nanoparticle has surfaced as a viable brain delivery vector that can solve the issues with existing approaches.

This study evaluates the implementation of a blood culture (BCx) algorithm in the neurology ICU (NICU) to reduce BCx event (BCE) rates. Results show a reduction in BCE rates, without increasing adverse outcomes. The findings support the feasibility of BCx algorithms for improving diagnostic stewardship in the specialized NICU population.

Purpose: Diffusion-weighted arterial spin labeling (DW-ASL) MRI has been proposed to determine the rate of water exchange (K) across the blood brain barrier (BBB). This study aims to further evaluate K MRI by comparing it with standard dynamic contrast-enhanced (DCE) MRI and histology in association with mannitol-induced disruption of the BBB.
Methods: DW-ASL was measured using a multiple b-value MRI protocol in normal rats at three post-labeling delays (N = 19), before and after intra-carotid injection of mannitol to disrupt BBB in one hemisphere (N = 13).

Alzheimer's disease (AD), an age-related neurodegenerative disease, brings huge damage to the society, to the whole family and even to the patient himself. However, until now, the etiological factor of AD is still unknown and there is no effective treatment for it. Massive deposition of amyloid-beta peptide(Aβ) and hyperphosphorylation of Tau proteins are acknowledged pathological features of AD.
