Association between carotid atherosclerosis and brain activation patterns during the Stroop task in older adults: an fNIRS investigation.

Neuroimage 2022 May 17:119302. Epub 2022 May 17.

MRC Unit for Lifelong Health and Ageing at University College London, Department of Population Science and Experimental Medicine, Institute of Cardiovascular Science, 1-19 Torrington Place, London, WC1E 7HB, United Kingdom. Electronic address:

There is an increasing body of evidence suggesting that vascular disease could contribute to cognitive decline and overt dementia. Of particular interest is atherosclerosis, as it is not only associated with dementia, but could be a potential mechanism through which cardiovascular disease directly impacts brain health. In this work, we evaluated the differences in functional near infrared spectroscopy (fNIRS)-based measures of brain activation, task performance, and the change in central hemodynamics (mean arterial pressure (MAP) and heart rate (HR)) during a Stroop color-word task in individuals with atherosclerosis, defined as bilateral carotid plaques (n = 33) and healthy age-matched controls (n = 33).

Z-scan optical method complements the Thioflavin T assay for investigation of anti-Alzheimer's impact of polyphenols.

Photodiagnosis Photodyn Ther 2022 May 17:102914. Epub 2022 May 17.

Biophotonics Lab, Faculty of Physics, Kharazmi University, Karaj 31979-37551, Iran; Applied Science Research Center, Kharazmi University, Karaj 31979-37551, Iran.

Polyphenols are tremendously effective in eliminating the amyloid-beta aggregations, the main hallmark of Alzheimer's disease. In recent years various nano drugs and biomaterials based on polyphenolic compounds have been synthetized to treat or prevent Alzheimer's disease, and the main in-vitro approach to investigate the anti-Alzheimer's properties of materials, is Thioflavin T assay. In spite of being very helpful, it has some drawbacks and cannot guarantee the accuracy of data, specifically in case of polyphenolic compounds; thus, rendering accurate results requires utilizing other assays along with Thioflavin T.

What have we learned from genome-wide association studies (GWAS) in Parkinson disease?

Ageing Res Rev 2022 May 17:101648. Epub 2022 May 17.

Centre for Genetic Epidemiology, Institute for Clinical Epidemiology and Applied Biometry, University of Tübingen, DE-72076 Tübingen, Germany. Electronic address:

After fifteen years of genome-wide association studies (GWAS) in Parkinson's disease (PD), what have we learned? Addressing this question will help catalogue the progress made towards elucidating disease mechanisms, improving the clinical utility of the identified loci, and envisioning how we can harness the strides to develop translational GWAS strategies. Here we review the advances of PD GWAS made to date while critically addressing the challenges and opportunities for next-generation GWAS. Thus, deciphering the missing heritability in underrepresented populations is currently at the reach of hand for a truly comprehensive understanding of the genetics of PD across the different ethnicities.
