Nivolumab in patients with metastatic DNA mismatch repair deficient/microsatellite instability–high colorectal cancer (CheckMate 142): results of an open-label, multicentre, phase 2 study

The Lancet Oncology, 2017
Summary Background Metastatic DNA mismatch repair–deficient/microsatellite instability–high (dMMR/MSI-H) colorectal cancer (mCRC) has a poor prognosis following conventional chemotherapy and exhibits high levels of tumour neoantigens, tumour-infiltrating

A gain‐of‐function mutation in microRNA 142 is sufficient to cause the development of T‐cell leukemia in mice

Cancer Science, 2023
MicroRNAs (miRNAs) play a crucial role in regulating gene expression. MicroRNA expression levels fluctuate, and point mutations and methylation occur in cancer cells; however, to date, there have been no reports of carcinogenic point mutations in miRNAs.

A double-layered paper-based analytical device for speciation and simultaneous determination of iron in waters within single-shot analysis

Talanta Open
This work demonstrates the use of a paper-based analytical device (PAD) for the speciation and the simultaneous determination of iron (Fe) in waters within a single-shot analysis. The PAD is designed as having stacked, double layers viz., the topside and

A Sensitive Resonance Rayleigh Scattering Method for Na+ Based on Graphene Oxide Nanoribbon Catalysis

International Journal of Analytical Chemistry, 2018
The gold nanoparticle reaction of HAuCl4-H2O2 was very slow under 60°C, and the as-prepared graphene oxide nanoribbons (GONRs) exhibited strong catalysis of the reaction to form gold nanoparticles (AuNP) that appeared a resonance Rayleigh scattering (RRS)
