Determination of liver iron concentration by magnetic resonance imaging (MRI) is becoming the new technique of choice for the diagnosis of iron overload in hereditary haemochromatosis and other liver iron surcharge diseases. Determination of hepatic iron concentration obtained by liver biopsy has been the gold standard for years. The development of MRI techniques, via signal intensity ratio methods or relaxometry, has provided a non-invasive and more accurate approach to the diagnosis of liver iron overload. This article reviews the available MRI methods for the determination of liver iron concentration and also evaluates the technique for the diagnosis and quantification of iron overload in different clinical practice scenarios.

Sarcoidosis is a disease that results from a combination of environmental and genetic factors. Its genetic basis however, is yet to be clarified. The purpose of this study is to determine whether single nucleotide polymorphisms (SNPs) of the B-cell activating factor (BAFF) and its receptor (BAFF-R) are associated with sarcoidosis. ⋯ Taken together, the results of this study suggest a possible relationship between BAFF SNPs, rs1041569 and rs9514828, and BAFF-R SNP rs61756766 with sarcoidosis susceptibility and their potential as biomarkers for the disease.

Previous studies have reported that microRNAs are implicated in the pathogenesis of diabetic nephropathy (DN). In this study, the underlying molecular mechanisms and diagnostic significance of miR-372-3p were investigated in the process of DN. ⋯ miR-372-3p might be a valuable therapeutic target and diagnostic marker for patients with DN.

Isoliquiritigenin, one of the components in the root of Glycyrrhiza glabra L., is a member of the flavonoids, which are known to have anti-tumor activity in vitro and in vivo. HMG-CoA reductase inhibitors, called statins, are used to reduce the risk of heart disease by lowering blood cholesterol levels. ⋯ The cells treated with isoliquiritigenin were assessed by MTT assay for 48 h as regards the cytotoxicity and anti-human pancreatic acinar cell tumor properties in normal (HUVEC) and human pancreatic acinar cell tumor cell lines, i.e. 266-6, TGP49, and TGP47. The IC50 values of isoliquiritigenin were 262, 389, and 211 μg/ml against 266-6, TGP49, and TGP47 cell lines, respectively. The viability of the human pancreatic acinar cell tumor cell line decreased dose-dependently in the presence of isoliquiritigenin. After clinical study, isoliquiritigenin can be utilized as an efficient drug in the treatment of human pancreatic acinar cell tumor in humans.

Translocase of the inner mitochondrial membrane 50 (TIMM50) is universally considered to play a key role in several malignancies. However, its role in predicting colorectal cancer (CRC) patient prognosis remains unclear. ⋯ TIMM50 may be a key factor for monitoring CRC and a new prognosis indicator for CRC patients.
