At liver magnetic resonance (MR) imaging in 38 patients, a breath-hold T2-weighted fast spin-echo (SE) pulse sequence optimized with fast recovery was compared with a conventional respiratory-triggered fast SE sequence and a breath-hold single-shot fast SE sequence. Mean signal-to-noise ratios for liver and contrast-to-noise ratios for hepatic lesions were higher with the breath-hold fast-recovery fast SE sequence than with the respiratory-triggered fast SE sequence (P <.05). Breath-hold fast-recovery images displayed better lesion clarity than did single-shot fast SE images (P <.05) and fewer image artifacts than did respiratory-triggered fast SE images (P <.05). The ability to determine lesion size and the overall image quality was best with the breath-hold fast-recovery sequence (P <.05). These results may justify use of the breath-hold fast-recovery fast SE pulse sequence for first-line T2-weighted MR imaging of the liver.

Liver cirrhosis is a chronic disease caused by long-term inflammation and fibrosis of the liver. Early identification and intervention in liver cirrhosis have become an important goal for researchers to explore the influence of some metabolic factors on the risk of liver cirrhosis in terms of genetic susceptibility. Data from genome-wide association studies (GWASs) of fourteen metabolic factors and liver cirrhosis were obtained from publicly available databases.

The emergence of nanopores in two-dimensional (2D) nanomaterials offers an attractive solid-state platform for high-throughput and low-cost DNA sequencing. However, several challenges remain to be addressed before their wide application, including the too-fast DNA translocation speed (compared to state-of-the-art single nucleoside detection techniques) and too large noise/signal ratios due to DNA fluctuations inside the nanopores. Here, we use molecular dynamics (MD) simulations to demonstrate the feasibility of utilizing RNA-DNA interactions in modulating DNA translocations in 2D MoS nanopores.
