Reproducibility of urinary biomarkers in multiple 24-h urine samples

Background: Limited knowledge regarding the reproducibility of biomarkers in 24-h urine samples has hindered the collection and use of the samples in epidemiologic studies.

Dietary flavonoid intake at midlife and healthy aging in women

Background: Dietary flavonoids have been related to lower risks of various chronic diseases, but it is unclear whether flavonoid intake in midlife helps to maintain good health and wellbeing in aging.

Associations between red meat intake and biomarkers of inflammation and glucose metabolism in women

Background: Greater red meat intake is associated with an increased type 2 diabetes and cardiovascular disease risk. However, the relation of red meat intake to biomarkers of inflammation and glucose metabolism has not been investigated thoroughly.

Crosstalk triggered safety standby pacing associated with an improperly seated ventricular lead

Ventricular Safety Standby (VSS) was designed to prevent the potentially serious consequences of crosstalk in many dual-chamber pulse generators. In this report, we describe a patient in whom the VSS was activated in a special way. When the VSS presents during bipolar sensing configuration, the clinician should notice the proper electrical contact between leads and pulse generator.

Vitamin D intake and risk of cardiovascular disease in US men and women

Background: Although studies have linked vitamin D deficiency to an increased risk of cardiovascular disease (CVD), evidence regarding whether vitamin D intake from foods or supplements is prospectively associated with lower CVD risk in healthy humans is limited and inconclusive.

Life-Long Implications of Developmental Exposure to Environmental Stressors: New Perspectives

The Developmental Origins of Health and Disease (DOHaD) paradigm is one of the most rapidly expanding areas of biomedical research. Environmental stressors that can impact on DOHaD encompass a variety of environmental and occupational hazards as well as deficiency and oversupply of nutrients and energy. They can disrupt early developmental processes and lead to increased...

Plasma and erythrocyte biomarkers of dairy fat intake and risk of ischemic heart disease

Background: The relation between dairy product intake and the risk of ischemic heart disease (IHD) remains controversial.

Islet Cell DNA Is a Target of Inflammatory Attack by Nitric Oxide

NO has been identified recently as the prime islet-toxic product of inflammatory macrophages. The adverse effects of IL-1 on isolated islets also have been reported to involve NO. We now show that exposure of an islet cell suspension to the NO donor nitroprusside or to activated macrophages leads to DNA strand breaks. Macrophages did not induce DNA damage in the presence of the...

Measuring alcohol consumption for genomic meta-analyses of alcohol intake: opportunities and challenges

Whereas moderate drinking may have health benefits, excessive alcohol consumption causes many important acute and chronic diseases and is the third leading contributor to preventable death in the United States. Twin studies suggest that alcohol-consumption patterns are heritable (50%); however, multiple genetic variants of modest effect size are likely to contribute to this...
