Methods: We conducted a retrospective cohort study to compare the risk of transitioning to immune active phase between inactive and indeterminate CHB and the incidence of hepatocellular carcinoma (HCC) and cirrhosis between untreated patients with indeterminate CHB (at baseline and throughout follow-up) and those who received treatment, following standard AASLD 2018 guidance.

Versatile Organometallic Synthesis of 0D/2D Metal@Germanane Nanoarchitectonics for Electrochemical Energy Conversion Applications.

Hydrogen-terminated 2D-Germanane (2D-GeH), a germanium-based 2D material akin to graphene, is receiving enormous attention owing to its predicted optoelectronic characteristics. However, experimental research of 2D-GeH is still in an early stage, and therefore its real implementation for task-specific applications will depend on the correct development of suitable chemical functionalization methods. Herein, a general and straightforward organometallic (OM) approach is provided for the robust functionalization of 2D-GeH with different 0D noble metal nanoparticles (M-NPs), resulting in 0D/2D M@GeH nanoarchitectonics.

Nevertheless, the biological role and mechanism of ARNTL2 are not fully elucidated in NPC.

Catalyst development for O-assisted oxidative dehydrogenation of propane to propylene.

O-Assisted oxidative dehydrogenation of propane (O-ODHP) could convert abundant shale gas into propylene as an important chemical raw material, meaning O-ODHP has practical significance. Thermodynamically, high temperature is beneficial for O-ODHP; however, high reaction temperature always causes the overoxidation of propylene, leading to a decline in its selectivity. In this regard, it is crucial to achieve low temperatures while maintaining high efficiency and selectivity during O-ODHP.
