Reproducibility of hepatic MR elastography across field strengths, pulse sequences, scan intervals, and readers

ConclusionThe magnitude of change across combinations of scan parameters is within acceptable clinical range, rendering liver stiffness through MRE a reproducible quantitative imaging biomarker. A lower reproducibility was observed for measurements under different field strengths/MRE sequences at a longer (2  weeks) interscan interval. Operators should be trained to acquire region of interest consistently in repeat examinations.

Abstract Dietary protein insufficiency has been linked to excessive triglyceride storage (TG) and non-alcoholic fatty liver disease (NAFLD) in developing countries. Hepatic TG accumulation following a low-protein diet may be due to altered peroxisomal, mitochondrial and gut microbiota function. Hepatic peroxisomes and mitochondria normally mediate metabolism of nutrients to provide energy and substrates for lipogenesis. Peroxisome biogenesis and activities can be modulated by odd (OCFA) and short-chain (SCFA) fatty acids that are derived from gut bacteria e.g. propionate and butyrate. Also produced during amino ac...

CONCLUSION: 18F-FDG PET/CT was able to evaluate the development of HCC in an experimental model of NAFLD non-invasively. From the standardization of PET/CT in this model, it is possible to us e this tool in future studies to monitor, in vivo and non-invasively, the progression of HCC.RESUMO BACKGROUND: O carcinoma hepatocelular (CHC) pode ser a última fase da doença hepática gordurosa não alcoólica (DHGNA). Modelos experimentais são cruciais para elucidação da patogênese do CHC secundário a DHGNA. A tomografia por emissão de pósitrons/tomogr...

AbstractBackgroundNon-alcoholic fatty liver disease (NAFLD) has a significant role in the development of coronary atherosclerosis, independent of traditional cardiovascular and metabolic risk factors. However, the role of myocardial glucose uptake in NAFLD patients who develop coronary atherosclerosis was unclear. The aim of the present study thus was to investigate the association between NAFLD with characteristic of coronary atherosclerotic plaque and myocardial glucose uptake measured by using18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET).Methods and ResultsA total of 418 consecutive subjects who had ...

In conclusion, TSF improved lipid accumulation and hepatic steatosis by inducing the AMPK/SIRT1 pathway-mediated autophagy. Introduction Nonalcoholic fatty liver disease (NAFLD) has become a worldwide health concern due to the increased incidence of obesity and diabetes. In addition, NAFLD is closely associated with the risk factors of coronary heart disease, such as metabolic syndrome, diabetes mellitus, and dyslipidemia, which are considered to be the leading causes of death (Wiest et al., 2017). Although our understanding of the pathogenesis of NAFLD has significantly improved, there is still no effective medica...

Conclusions: Our study shows that a higher burden of liver steatosis seems to be associated with less severe stroke and better functional outcome after ischemic stroke or TIA. Introduction Non-alcoholic fatty liver disease (NAFLD) is a spectrum of diseases from simple steatosis to steatohepatitis with varying degree of fibrosis, and liver cirrhosis (1, 2). NAFLD is becoming the most common chronic liver disease worldwide including Korea, affecting approximately 25% of the general population (3, 4). NAFLD is closely associated with obesity, insulin resistance, and type 2 diabetes mellitus, and is even recognized as ...

Conclusion: The obesity-related SNP rs545854 was correlated with the serum uric acid level and risk of hyperuricemia in a male Chinese population. Therefore, men carrying this SNP could benefit from limiting their meat consumption to prevent hyperuricemia. These findings suggest an underlying genetic link between obesity and hyperuricemia worthy of further exploration. Introduction Serum uric acid (SUA) is a final product of the metabolic breakdown of purine oxidation (1). Since humans lack the gene for uricase that converts uric acid into a soluble form, the human uric acid level tends to be higher than that of othe...
