Solar-driven overall conversion of CO and HO into fuels and chemicals shows an ultimate strategy for carbon neutrality yet remains a huge challenge. Herein, an integrated photocatalytic redox architecture of Zn NPs/GaN Nanowires (NWs)/Si is explored for light-driven overall conversion of CO and HO into CH and HO simultaneously without any external sacrificial agents and additives. The as-designed architecture affords a benchmark CH activity of 189 mmol g h with a high selectivity of 93.

Background: The Murray law-based quantitative flow ratio (μFR) is an emerging technique that requires only 1 projection of coronary angiography with similar accuracy to quantitative flow ratio (QFR). However, it has not been validated for the evaluation of noninfarct-related artery (non-IRA) in acute myocardial infarction (AMI) settings. Therefore, our study aimed to evaluate the diagnostic accuracy of μFR and the safety of deferring non-IRA lesions with μFR >0.

Article Synopsis
  • - The study aimed to investigate whether having an appendectomy reduces the long-term risk of colorectal cancer, particularly for tumors associated with the bacterial species Fusobacterium nucleatum, which is linked to colorectal tumor development.
  • - Using data from extensive cohort studies, researchers found that 2811 cases of colorectal cancer were recorded, with appendectomy appearing to lower the incidence of F. nucleatum-positive cancers (hazard ratio of 0.53) but not F. nucleatum-negative cancers (hazard ratio of 0.98).
  • - The findings suggest that while appendectomy may reduce the risk of developing certain types of colorectal cancer (specifically F. nucleatum-positive ones), it does not significantly impact the risk for other types,

  • Research suggests that enterotoxigenic Bacteroides fragilis (ETBF) may play a role in colorectal cancer development, particularly in tumors with specific genetic markers like high-level CpG island methylator phenotype (CIMP-high) and BRAF mutations.
  • The study utilized quantitative PCR to measure levels of Bacteroides fragilis and ETBF in colorectal cancer cases, finding that high levels of these bacteria are significantly linked to the presence of CIMP-high and MSI-high tumors.
  • Overall, the results provide evidence that Bacteroides fragilis and ETBF may influence colorectal cancer progression through particular genetic pathways, although they do not appear to affect patient survival rates.

Background A simplification of the Liver Imaging Reporting and Data System (LI-RADS) version 2018 (v2018), revised LI-RADS (rLI-RADS), has been proposed for imaging-based diagnosis of hepatocellular carcinoma (HCC). Single-site data suggest that rLI-RADS category 5 (rLR-5) improves sensitivity while maintaining positive predictive value (PPV) of the LI-RADS v2018 category 5 (LR-5), which indicates definite HCC. Purpose To compare the diagnostic performance of LI-RADS v2018 and rLI-RADS in a multicenter data set of patients at risk for HCC by performing an individual patient data meta-analysis.

Background: The adult mammalian heart is incapable of regeneration, whereas a transient regenerative capacity is maintained in the neonatal heart, primarily through the proliferation of preexisting cardiomyocytes. Neonatal heart regeneration after myocardial injury is accompanied by an expansion of cardiac fibroblasts and compositional changes in the extracellular matrix. Whether and how these changes influence cardiomyocyte proliferation and heart regeneration remains to be investigated.

Metal phthalocyanine (MPc) material with a well-defined MN moiety offers a platform for catalyzing the oxygen reduction reaction (ORR), while the practical performance is often limited by the insufficient O adsorption due to the planar MN configuration. Here, a design (called Gr-M -O-M Pc) is proposed, where the metal of MPc (M ) is axially coordinated to a single metal atom in graphene (Gr-M ) through a bridge-bonded oxygen atom (O), introducing effective out-of-plane polarization to promote O adsorption on MPc. Manipulating the out-of-plane polarization charge by varying types of M and M (M  = Fe/Co/Ni, M  = Ti/V/Cr/Mn/Fe/Co/Ni) in the axial coordination zone of -M -O-M - are examined by density functional theory simulations.
