Background: Risk perception with respect to death is a prerequisite for patients with advanced cancer when the time comes to make medical decisions. However, the nature of death risk perception remains unclear.
Method: In-depth interviews were conducted with 28 patients with advanced cancer who were recruited from two hospitals and one home-based hospice in Fujian, China.
Forty-nine compounds, including six previously unknown together with forty-three known ones, were isolated from the fruits of Foeniculum vulgare Mill. Their structures were elucidated using high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), infrared spectroscopy (IR), ultraviolet-visible spectroscopy (UV), nuclear magnetic resonance (NMR), and electronic circular dichroism (ECD) methods. All isolates were evaluated their anti-inflammatory activity.

However, they are subject to capacity fading during cycling, such as structural degradation and irreversible oxygen release, especially under high voltage.
View Article and Find Full Text PDFOwing to the capacity boost from anion redox activities, cation-disordered rock-salt oxides are considered as potential candidates for the next-generation of high energy density Li-ion cathode materials. Unfortunately, the anion redox process that affords ultra-high specific capacity often triggers irreversible O release, which brings about structural degradation and rapid capacity decay. In this study, we present a partial chlorine (Cl) substitution strategy to synthesize a new cation-disordered rock-salt compound of LiTiMnOCl and investigate the impact of Cl substitution on the oxygen redox process and the structural stability of cation-disordered rock-salt cathodes.

Aim: To compare the fine needle-assisted puncture (FNP) positioning technique and the conventional puncture (CP) technique for the safety and efficacy of CT-guided MWA in treating hepatocellular carcinoma (HCC).
Cation-disordered rock-salt cathode materials are featured by their extraordinarily high specific capacities in lithium-ion batteries primarily contributed by anion redox reactions. Unfortunately, anion redox reactions can trigger oxygen release in this class of materials, leading to fast capacity fading and major safety concern. Despite the capability of absorbing structural distortions, high-ratio d transition-metal cations are considered to be unfavorable in design of a new cation-disordered rock-salt structure because of their electrochemically inactive nature.

We analyzed 35 advanced ICC patients retrospectively, including the apatinib plus DEB-TACE group (n=10), the apatinib plus cTACE group (n=12) and the apatinib group (n=13). Treatment response, survival data (including progression-free survival (PFS) and overall survival (OS)) and adverse events were assessed during the follow-up.

Direct printing of transparent conducting oxide (TCO) nanocrystal dispersions holds great promise in solution-processed optoelectronics due to its advantages of low material waste and direct patterning on substrates. An essential prerequisite for printable TCO colloidal solutions is the effective stabilization of TCO nanocrystals to prevent their strong aggregation. In situ stabilization uses long-chain ligands to provide interparticle steric repulsion between TCO nanocrystals during the growth of TCO nanocrystals.
