An electrochemiluminescence (ECL) immunosensor was developed for the highly sensitive and specific detection of heart-type fatty acid binding protein (H-FABP) and the rapid diagnosis of acute myocardial infarction (AMI). H-FABP is a biomarker that is highly specific to cardiac tissue and is associated with a range of cardiac diseases. Following myocardial injury, the rate of increase in H-FABP levels is greater than that observed for myoglobin and troponin.

In this study, we used meso-tetra (4-carboxyphenyl) porphyrin (TCPP) as an organic ligand to modify a lanthanide-based metal-organic framework as an electrochemiluminescence (ECL) platform to sensitively detect anti-Müllerian hormone (AMH). La-MOF amplified the ECL signal by suppressing the aggregation-caused quenching created by TCPP self-aggregation. Utilizing the reversible cycling of the mixed-valence transition metal ion (Cu/Cu and Mo/Mo) and the electrical conductivity of CuMoS and silver nanoparticle (AgNP), CuMoS-AgNP as a dual co-reaction promoter constantly generated sulfate radical anions (SO) and thus amplified the ECL signal.

Introduction: Lung cancer is the most common cancer worldwide, among which non-small cell lung cancer (NSCLC) accounts for about 80% of all lung cancers. Chemotherapy, a mainstay modality for NSCLC, has demonstrated restricted effectiveness due to the emergence of chemo-resistance and systemic side effects. Studies have indicated that combining chemotherapy with phototherapy, such as photodynamic therapy (PDT) and photothermal therapy (PTT), can enhance efficacy of therapy.

Article Synopsis
  • Neuroblastoma (NB) is a tricky cancer that can spread a lot and is different in many ways from person to person.
  • This study looked at 95 kids with NB to measure different factors related to the tumors using special scans (PET/CT) and tried to see if these measurements could help predict how well the kids would do in the future.
  • The results showed that two specific measurements from the whole-body tumors helped predict survival chances, while other measurements from the primary tumor were less helpful, indicating how important it is to understand the tumors fully.*

Article Synopsis
  • Viruses need to attach to specific cell surface receptors to invade host cells, but many of these receptors are still unidentified, making research challenging.
  • This study analyzed known human viruses and their receptors using bioinformatics to understand the characteristics that make some membrane proteins more likely to act as virus receptors.
  • Findings showed that virus receptors generally have higher expression levels and lower sequence conservation than other membrane proteins, with notable variations in expression due to age and significant dysregulation in tumors, leading to the development of GateView, a platform for further virus receptor research.

Dechlorination of chloropyridines can eliminate their detrimental environmental effects. However, traditional dechlorination technology cannot efficiently break the C-Cl bond of chloropyridines, which is restricted by the uncontrollable nonselective species. Hence, we propose the carbonate species-activated hydrogen peroxide (carbonate species/HO) process wherein the selective oxidant (peroxymonocarbonate ion, HCO) and selective reductant (hydroperoxide anion, HO) controllably coexist by manipulation of reaction pH.
