BACKGROUND Total nutrient intake (TNI) is intake from food and supplements. This provides an assessment of nutrient adequacy and the prevalence of excessive intake, as well as the response with respect to biomarkers. Cod liver oil (CLO) is the most frequently consumed supplement in the UK, containing nutrients that might have varying influences on health. We calculated TNI for vitamins A, D and...

Basic helix-loop-helix (bHLH) regulatory proteins are known to bind to a single DNA consensus sequence referred to as an E-box. The E-box is present in the regulatory elements of many developmentally controlled genes, including most muscle-specific genes such as troponin I (TnI). Although the E-box consensus is minimally defined as CANNTG, the adjacent nucleotides of functional E-boxes are vari...

Cardiac troponin I (TnI) knockout mice exhibit a phenotype of sudden death at 17-18 days after birth due to a progressive loss of TnI. The objective of this study was to gain insight into the physiological consequences of TnI depletion and the cause of death in these mice. Cardiac function was monitored serially between 12 and 17 days of age by using high-resolution ultrasonic imaging and Doppl...

AIMS Heart muscle contraction is regulated via the β-adrenergic response that leads to phosphorylation of Troponin I (TnI) at Ser22/23, which changes the Ca(2+) sensitivity of the cardiac myofilament. Mutations in thin filament proteins that cause dilated cardiomyopathy (DCM) and some mutations that cause hypertrophic cardiomyopathy (HCM) abolish the relationship between TnI phosphorylation and...

BACKGROUND Excessive immune-mediated inflammatory reactions play a deleterious role in postinfarction ventricular remodeling. Interleukin-37 (IL-37) emerges as an inhibitor of both innate and adaptive immunity. However, the exact role of IL-37 and IL-37 plus troponin I (TnI)-treated dendritic cells (DCs) in ventricular remodeling after myocardial infarction (MI) remains elusive. METHODS AND R...

BACKGROUND The assessment of cardiospecific troponins is the main stay for diagnosing myocardial injury, although their diagnostic sensitivity remains suboptimal at patient admission to the emergency department (ED), thus paving the way for translational research to identify early and complementary biomarkers which may help improve the diagnostic sensitivity of high-sensitivity troponin immunoa...

Introduction Soluble urokinase-type plasminogen activator receptor (suPAR) strongly predicts outcomes and incident chronic kidney disease (CKD) in patients with cardiovascular disease (CVD). Whether the association between suPAR and CKD is a reflection of its overall association with chronic inflammation and poor CVD outcomes is unclear. We examined whether CVD biomarkers, including high-sensit...

OBJECTIVES The aims of this study were to assess the prognostic value of cardiac troponin I levels, measured with a new high-sensitivity assay, in low-risk patients with stable coronary artery disease (CAD) and to contrast its determinants and prognostic merit with that of high-sensitivity cardiac troponin T (hs-TnT). BACKGROUND New, highly sensitive cardiac troponin assays permit evaluation ...

Approximately 60% of morphine is glucuronidated to morphine-3-glucuronide (M3G) which may aggravate preexisting pain conditions. Accumulating evidence indicates that M3G signaling through neuronal Toll-like receptor 4 (TLR4) may be central to this proalgesic signaling event. These events are known to include elevated neuronal excitability, increased voltage-gated sodium (NaV) current, tactile a...

We have studied the effect of substrates [glass and Si(10 0)], of Ni thickness (tNi) and of the deposition rate [v1 1⁄4 13nm/min and v2 1⁄4 22nm/min] on the structural and electrical properties of evaporated Ni thin films. The Ni thickness, measured by the Rutherford backscattering (RBS) technique, ranges from 28 to 200nm. From X-ray diffraction, it was found that all samples are polycrystallin...
