Anatomy of the pontine arteries and perforators of the basilar artery in humans
J Anat. 2023 Jul 6. doi: 10.1111/joa.13927. Online ahead of print.ABSTRACTCerebral blood flow constitutes a critical area of interest for neurologists, neurosurgeons, and interventional radiologists as a social burden related to ischemic stroke, hemorrhagic stroke, and vascular dementia is expected to intensify. There is a great need to develop new and effective therapies, therefore deepening understanding of cerebrovascular anatomy, physiology, and pathology is crucial. The main aim of the study was to develop a comprehensive classification of the pontine arteries considering their typology, relations to the cranial nerve...

Edaravone Dexborneol Alleviates Neuroinflammation by Reducing Neuroglial Cell Proliferation and Suppresses Neuronal Apoptosis/Autophagy in Vascular Dementia Rats
In this study, we established the VD model of rats by bilateral carotid artery occlusion to explore the neuroprotective effect of EDB and its mechanism. Morris Water Maze test was applied to assess the cognitive function of rats. H&E and TUNEL staining were applied to observe the cellular structure of the hippocampus. Immunofluorescence labeling was used to observe the proliferation of astrocytes and microglia. ELISA was applied to examine the levels of TNF-α, IL-1β and IL-6, and RT-PCR was applied to examine their mRNA expression levels. Western blotting was applied to examine apoptosis-related proteins (Bax, Bcl-2,...

Sex differences in cognitive impairment after focal ischemia in middle-aged rats and the effect of iv miR-20a-3p treatment
Neurobiol Aging. 2023 May 5;129:168-177. doi: 10.1016/j.neurobiolaging.2023.05.001. Online ahead of print.ABSTRACTStroke is a major cause of death and disability worldwide and is also a leading cause of vascular dementia and Alzheimer's disease, with older women experiencing accelerated decline. Our previous studies show that intravenous (iv) injections of miR-20a-3p, a small noncoding RNA (miRNA) delivered after stroke improves acute stroke outcomes in middle-aged male and female rats. The present study tested whether mir-20a-3p treatment would also ameliorate stroke-induced cognitive decline in the chronic phase. Acyclic...

Estimate of the prevalence of subjects with chronic diseases in a province of Northern Italy: a retrospective study based on administrative databases
Conclusions Despite the difficulty of having a unique definition of chronic disease, the prevalence obtained was coherent with the estimates reported by other national surveillance systems such as Passi and Passi d’Argento. Underestimates were observed when international comparisons were done; however, when we used less stringent definitions of chronic diseases, similar results were obtained.

Higher serum uric acid is associated with poorer cognitive performance in healthy middle-aged people: a cross-sectional study
AbstractAge-related cognitive impairment can occur many years before the onset of the clinical symptoms of dementia. Uric acid (UA), a metabolite of purine-rich foods, has been shown to be positively associated with improved cognitive function, but such association remains controversial. Moreover, most of the previous studies investigating the association included elderly participants with memory-related diseases. Therefore, the present study aimed at investigating whether serum UA (sUA) is associated with cognitive performance in healthy middle-aged individuals. We conducted a cross-sectional study on a cohort of middle-a...
