Poor Sleep Linked To Dangerous Plaque Buildup In Arteries

By Sandee LaMotte, CNN (CNN) — Here’s another reason why getting a good night’s sleep should be on your must-do list: Sleeping fewer than six hours a night or waking frequently raises your risk of developing damaging plaque in arteries throughout your body, not just your heart. Previous research has shown poor sleep to be strongly associated with coronary heart disease, but “This is the first study to show that objectively measured sleep is independently associated with atherosclerosis throughout the body,” José Ordovás, director of nutrition and genomics at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, said in a statement. Ordovás was senior author of a study on these findings, published Monday in the journal of the American College of Cardiology. The increase of plaque, called atherosclerosis, in your extremities puts you at increased risk for strokes, digestive problems and poor circulation that leads to numbness and pain in your extremities, as well as heart disease. Objective measurements The study looked at nearly 4,000 Spanish men and women, with an average age of 46, who had no history of heart disease. Each person wore an actigraph, a small device that measured the length and quality of sleep, over seven nights. Quality of sleep was defined by how often they woke up and how often they moved during the sleep phases. The subjects were divided into four groups based on their...

Euxanthone is a xanthone compound extracted from Polygala caudata, and shows vasodilatory action. The aim of this study was to determine the potential pharmacological effects of euxanthone against oxidized low-density lipoprotein (ox-LDL)-induced endothelial cell injury.Material and methodsHuman umbilical vein endothelial cells (HUVECs) were expo...

As a step towards understanding the underlying molecular mechanisms of this contribution, we aimed to examine the association of four microRNAs' (miR-222, -137, -214, -181b) levels with BRAFV600E and clinicopathological features in PTC tissues and fine needle aspiration (FNA...

Authors: Dvornek NC, Yang D, Ventola P, Duncan JS Abstract Deep learning has become the new state-of-the-art for many problems in image analysis. However, large datasets are often required for such deep networks to learn effectively. This poses a difficult challenge for many medical image analysis problems in which only a small number of subjects are available, e.g., patients undergoing a new treatment. In this work, we propose a number of approaches for learning generalizable recurrent neural networks from smaller task-fMRI datasets: 1) a resampling method for ROI-based fMRI analysis to create augmented data; 2) i...

When Elma van Vliet decided to start asking her mother about her life, the results were remarkableIt wasn ’t until Margreeth van Vliet-Smit was diagnosed with inoperable cancer in 2001 that Elma van Vliet realised how much she didn’t know about her own mother. She didn’t know what dreams and adventures Margreeth had had when she was a young woman. She didn’t know what her mother had done on Satu rday afternoons as a small girl. She didn’t even know how to make the chicken soup Margreeth had always made when her daughter was ill. “And she was the only person in the world who knew how to m...

Authors: Levy M, Barletta S, Huang H, Grossman SA, Rodriguez FJ, Ellsworth SG, Dzaye O, Holdhoff M Abstract There has been controversy about the presence and potential role of aquaporin-4 (AQP4) in glioblastoma (GBM). We analyzed tissue from 22 patients with newly-diagnosed GBM as well as matching tissue from 17 of these cases who underwent repeat resection for suspected recurrence and performed immunohistochemical analysis for AQP-4 expression. While some degree of AQP4 expression was detected in all 22 cases (39 samples), there was no clear relationship between staining pattern and disease status (active versus i...

Authors: Draijer L, Benninga M, Koot B Abstract INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in children and adults in industrialized countries. Besides liver-related morbidity, NAFLD is also associated with an increased risk of cardiovascular disease, type 2 diabetes and mortality at adult age. However, despite the high prevalence and serious complications, diagnosing and staging of disease remains complicated due to a lack of accurate screening tools and non-invasive methods to detect fibrosis. Areas covered: Recent insights in epidemiology, pathogenesis, diagno...

Authors: Voigt RM, Forsyth CB, Keshavarzian A Abstract INTRODUCTION: Circadian rhythms regulate much of gastrointestinal physiology including cell proliferation, motility, digestion, absorption, and electrolyte balance. Disruption of circadian rhythms can have adverse consequences including the promotion of and/or exacerbation of a wide variety of gastrointestinal disorders and diseases. Areas covered: In this review, we evaluate some of the many functions that are regulated by circadian rhythms and how dysregulation of these functions may contribute to disease. This review also discusses some common gastrointestin...
