Silver frameworks based on a tetraphenylethylene-imidazole ligand for electrocatalytic reduction of CO to CO.

Metal-organic frameworks (MOFs) can be used as electrocatalysts for the CO reduction reaction (CORR) because of their well-dispersed metal centers. Silver is a common electrocatalyst for reduction of CO to CO. In this study, two Ag-MOFs with different structures of [AgO(TIPE)](NO) (Ag-MOF1) and [Ag(TIPE)CFSO] (Ag-MOF2) [TIPE = 1,1,2,2-tetrakis(4-(imidazol-1-yl)phenyl)ethene] were synthesized and used for CO electroreduction.

Red cell distribution width: A predictor of the severity of hypertriglyceridemia-induced acute pancreatitis.

Background: Compared with patients with other causes of acute pancreatitis, those with hypertriglyceridemia-induced acute pancreatitis (HTG-AP) are more likely to develop persistent organ failure (POF). Therefore, recognizing the individuals at risk of developing POF early in the HTG-AP process is a vital for improving outcomes. Bedside index for severity in acute pancreatitis (BISAP), a simple parameter that is obtained 24 h after admission, is an ideal index to predict HTG-AP severity; however, the suboptimal sensitivity limits its clinical application.

Fasting mimicking diet inhibits tumor-associated macrophage survival and pro-tumor function in hypoxia: implications for combination therapy with anti-angiogenic agent.

Background: Recent research shows that tumor-associated macrophages (TAMs) are the primary consumers of glucose in tumor tissue, surpassing that of tumor cells. Our previous studies revealed that inhibiting glucose uptake impairs the survival and tumor-promoting function of hypoxic TAMs, suggesting that glucose reduction by energy restriction (calorie restriction or short-term fasting) may has a significant impact on TAMs. The purpose of this study is to verify the effect of fasting-mimicking diet (FMD) on TAMs, and to determine whether FMD synergizes with anti-angiogenic drug apatinib via TAMs.
