Worldwide, coffee is one of the most popular beverages consumed. Several studies have suggested a protective role of coffee, including reduced risk of Alzheimer’s disease (AD). However, there is limited longitudinal data from cohorts of older adults reporting associations of coffee intake with cognitive decline, in distinct domains, and investigating the neuropathological mechanisms underpinning any… Continue reading Higher Coffee Consumption Is Associated With Slower Cognitive Decline and Less Cerebral Aβ-Amyloid Accumulation Over 126 Months: Data From the Australian Imaging, Biomarkers, and Lifestyle Study

Consumption of coffee and tea and risk of developing stroke, dementia, and poststroke dementia: A cohort study in the UK Biobank
Previous studies have revealed the involvement of coffee and tea in the development of stroke and dementia. However, little is known about the association between the combination of coffee and tea and the risk of stroke, dementia, and poststroke dementia. Therefore, we aimed to investigate the associations of coffee and tea separately and in combination… Continue reading Consumption of coffee and tea and risk of developing stroke, dementia, and poststroke dementia: A cohort study in the UK Biobank
Discovery of a novel pseudo β-hairpin structure of N-truncated amyloid-β for use as a vaccine against Alzheimer’s disease
One of the hallmarks of Alzheimer’s disease (AD) are deposits of amyloid-beta (Aβ) protein in amyloid plaques in the brain. The Aβ peptide exists in several forms, including full-length Aβ1-42 and Aβ1-40 – and the N-truncated species, pyroglutamate Aβ3-42 and Aβ4-42, which appear to play a major role in neurodegeneration. We previously identified a murine… Continue reading Discovery of a novel pseudo β-hairpin structure of N-truncated amyloid-β for use as a vaccine against Alzheimer’s disease
Serum Nonesterified #Fatty Acids and Incident #Stroke: The CHS
Significant associations between total nonesterified fatty acid (NEFA) concentrations and incident stroke have been reported in some prospective cohort studies. We evaluated the associations between incident stroke and serum concentrations of nonesterified saturated, monounsaturated, polyunsaturated, and trans fatty acids. Methods and ResultsCHS (Cardiovascular Health Study) participants (N=2028) who were free of stroke at baseline (1996–1997)… Continue reading Serum Nonesterified #Fatty Acids and Incident #Stroke: The CHS
Estimating dose-response relationships for vitamin #D with #coronary heart disease, #stroke, and all-cause mortality: observational and Mendelian randomisation analyses
SummaryBackgroundRandomised trials of vitamin D supplementation for cardiovascular disease and all-cause mortality have generally reported null findings. However, generalisability of results to individuals with low vitamin D status is unclear. We aimed to characterise dose-response relationships between 25-hydroxyvitamin D (25[OH]D) concentrations and risk of coronary heart disease, stroke, and all-cause mortality in observational and Mendelian… Continue reading Estimating dose-response relationships for vitamin #D with #coronary heart disease, #stroke, and all-cause mortality: observational and Mendelian randomisation analyses
Role of Adipocyte Na,K-ATPase Oxidant Amplification Loop in #Cognitive Decline and #Neurodegeneration
•Adipocytes induce phenotypical changes in neurodegeneration through adipocyte NKAL.•Adipocyte specific NaKtide inhibited NKAL and improved systemic homeostasis.•NaKtide improved adipocyte phenotype and improved markers of neurodegeneration.•NaKtide improved genomic profile of hippocampus and adipose tissue in WD fed mice. SummaryRecent studies suggest that a western diet may contribute to clinical neurodegeneration and dementia. Adipocyte-specific expression of the… Continue reading Role of Adipocyte Na,K-ATPase Oxidant Amplification Loop in #Cognitive Decline and #Neurodegeneration
Digging for data: How #sleep is losing out to roster design, sleep disorders, and lifestyle factors
Highlights•Shift start times <06:00, may result in sleep loss resulting in poor alertness. •Risk of sleep disorders increased with body mass and age. •Prevalence of shiftwork disorder and obstructive sleep apnea in mining is high. •Biomathematical modeling may be used to eliminate or reduce organizational risk. AbstractShift workers employed at a remote mining operation may… Continue reading Digging for data: How #sleep is losing out to roster design, sleep disorders, and lifestyle factors
Study: People Are Getting #Dumber
IQ scores have been steadily falling for decades, but genes aren't to blame – their environment is at fault. New research published this week in Proceedings of the National Academy of the Sciences of the United States of America examined the IQ scores of men born between 1962 and 1991. Researchers found that scores increased… Continue reading Study: People Are Getting #Dumber
Identification of a choroid plexus vascular barrier closing during #intestinal inflammation
Locking down access to the brainInflammatory bowel disease is best known for intestinal symptoms but can also cause a variety of extraintestinal manifestations in other organs. It can also be associated with cognitive and psychiatric effects, including anxiety and depression. Using mouse models of intestinal inflammation, Carloni et al. uncovered a potential pathogenic link between… Continue reading Identification of a choroid plexus vascular barrier closing during #intestinal inflammation
