Article Synopsis
  • Enzymes are essential for life processes and their regulation through expression and activation is crucial, but current analysis methods often only focus on concentration or activation separately.
  • A novel biresponsive strategy using N-methyl mesoporphyrin IX (NMM) and G-quadruplex nucleic acid enzyme (G4h DNAzyme) allows for simultaneous analysis of both enzyme concentration and activation through specific fluorescence changes.
  • This method shows potential for effective bioanalysis by not only focusing on G4h DNAzyme but also being extendable to other enzymes, enhancing our overall understanding of enzymatic functions.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening immune disorder categorized as familial HLH or secondary HLH. Our case report describes a 63-year-old woman with epilepsy whose clinical signs were unremitting fever and altered consciousness. Primary abnormalities consisted of fever, splenomegaly, cytopenia, hypertriglyceridemia, hyperferritinemia and hemophagocytosis in the bone marrow.

The mutation status of epidermal growth factor receptor (EGFR) exon 19 is of great importance for predicting sensitivity to tyrosine kinase inhibitors (TKIs) in the treatment of non-small-cell lung cancer (NSCLC). However, the development of simple, sensitive, and no-nonspecific amplification platforms for EGFR 19del detection in NSCLC remains a challenge. Herein, we developed a novel, simple, and highly sensitive naked-eye assay utilizing CRISPR/Cas12a-triggered no-nonspecific nucleic acid amplification (NAA) with rolling circle amplification (RCA) as a model for EGFR 19del detection.

Tetanus is a potentially fatal public health illness resulted from the neurotoxins generated by . is not easily culturable and culturing the relevant bacteria from infected wounds has rarely been useful in diagnosis; PCR-based assays can only be conducted at highly sophisticated laboratories. Therefore, a real-time recombinase polymerase amplification assay (Exo-RPA) was constructed to identify the fragments of the neurotoxin gene of .

Background: Small supernumerary marker chromosomes (sSMCs), are additional abnormal chromosomes, which can't be detected accurately by banding cytogenetic analysis. Abnormal phenotypes were observed in about 30% of SMC carriers. Duplication of chromosome 15 and related disorders, characterized by hypotonia motor delays, autism spectrum disorder (ASD), intellectual disability, and epilepsy including infantile spasms, might be account for 50% of the total sSMCs.

Thalassemia is one of the most common hereditary blood disorders. Epidemiological data regarding the prevalence and distribution of mutations is important for planning a thalassemia control program. To reveal the prevalence of thalassemia and mutation spectrum in the Yulin region of southern China, we screened 130,318 individuals from Yulin region by hematological and genetic analysis.
