Urinary liver-type fatty acid binding protein is an independent predictor of stroke and mortality in individuals with type 1 diabetes
DIABETOLOGIA - 01 Sep 2017
AIMS/HYPOTHESIS:
In type 1 diabetes, cardiovascular disease (CVD) and diabetic nephropathy progress in parallel, thereby potentiating the risk of premature death during their development. Since urinary liver-type fatty acid binding protein (L-FABP) predicts the progression of diabetic nephropathy, the aim of this study was to investigate whether urinary L-FABP also predicts cardiovascular ou...
Chromatin context and ncRNA highlight targets of MeCP2 in brain
RNA BIOL - 01 Nov 2013
The discovery that Rett syndrome (RTT) is caused by mutation of the methyl-CpG-binding-protein MeCP2 provided a major breakthrough in understanding the neurodevelopmental disorder and accelerated MeCP2 research. However, gene regulation by MeCP2 is complicated. The current consensus for MeCP2 remains as a classical repressor complex, with major emphasis on its role in methylation-dependent bind...

Plasma lipidomic profiling in patients with rheumatoid arthritis
METABOLOMICS - 24 Jan 2017
Introduction
Rheumatoid arthritis (RA) is linked to increased cardiovascular morbidity and mortality, not completely explained by traditional risk factors. Importantly, the increased risk occurs despite lower levels of total and low-density lipoprotein cholesterol. Whilst systemic inflammation may be a factor, it is possible that changes in individual lipid species contribute to the increase...
Dietary advanced glycation end products and risk factors for chronic disease: a systematic review of randomised controlled trials
NUTRIENTS - 01 Mar 2016
Dietary advanced glycation end-products (AGEs) form during heating and processing of food products and are widely prevalent in the modern Western diet. Recent systematic reviews indicate that consumption of dietary AGEs may promote inflammation, oxidative stress and insulin resistance. Experimental evidence indicates that dietary AGEs may also induce renal damage, however, this outcome has not ...
