Background: To evaluate proton-density fat-fraction (PDFF) and intravoxel incoherent motion (IVIM) techniques, and human 25-hydroxyvitamin D3 (25OH-VitD3) levels, as potential biomarkers in patients with colorectal cancer with liver metastasis (CRCLM). Changes were compared with those related to chemotherapy-associated steatohepatitis (CASH) and sinusoidal obstruction syndrome (SOS).
Methods: 63 patients with pathologically confirmed colorectal adenocarcinoma received 4-6 courses of NC before liver resection and underwent magnetic resonance imaging (MRI) with iterative decomposition of water and fat with echo asymmetry and least-squares estimation quantification and IVIM sequences.

The use of various optical methods for detection of dopamine (DA), such as colorimetry, fluorometry, surface-enhanced Raman spectroscopy (SERS), and electrochemiluminescence (ECL), has progressively matured over the past decade. However, the development of a simple, inexpensive, and quick detection method for dopamine still remains a challenge. Herein, we used stable black phosphorus quantum dots (BPQDs) for sensitive and selective detection of dopamine by UV-Vis spectroscopy.

However, the high cost and low abundance limit wide application of such metals. As such, one challenging issue is the development of low-cost and high-efficiency electrocatalysts for such purposes.
