The three members of the genus capripoxvirus (CaPV), lumpy skin disease virus (LSDV), sheeppox virus (SPPV), and goatpox virus (GTPV) have common hosts and areas of overlapping geographical distribution with Rift Valley fever virus (RVFV). Hence, to ensure more cost-effective disease surveillance we developed and evaluated a Luminex assay for the simultaneous detection of antibodies against CaPV and RVFV in domestic ruminants. In cattle, the assay had a sensitivity (Se) of 98.

Objective: Referring all women who tested positive for human papillomavirus (HPV) 16/18 to colposcopy may lead to potential over-referral issues. Triage tests based on cytology results face challenges in achieving accurate diagnoses. Our study aims to assess the clinical effectiveness of PAX1/JAM3 methylation (CISCER) test as a triage method for HPV 16/18-positive women.

Background: Esophageal cancer (ECa) is one of the most deadly cancers, with increasing incidence worldwide and poor prognosis. While endoscopy is recommended for the detection of ECa in high-risk individuals, it is not suitable for large-scale screening due to its invasiveness and inconvenience.
Methods: In this study, a novel gene methylation panel was developed for a blood-based test, and its diagnostic efficacy was evaluated using a cohort of 304 participants (203 cases, 101 controls).
Efficient electrochemiluminescence sensor utilizing Zr-PyTCPPMOF for swift hydrogen sulfide detection.

The ultrahigh-sensitive detection of HS is reported using a novel dual-ligand metal-organic framework (MOF) electrochemiluminescence (ECL) sensor. By combining tetrakis(4-carboxyphenyl) porphyrin (TCPP) and 1,3,6,8-tetrakis(4-carboxyphenyl) pyrene (TBAPy) as ligands and employing zirconium as the metal source, a spindle-shaped Zr-PyTCPPMOF was successfully designed and synthesized. Notably, the multiple nitrogen structures of porphyrin provided abundant binding sites for sulfur (S), further enhancing the ECL signal of Zr-PyTCPPMOF.

Rapid diagnostic tools for Porphyromonas gingivalis (Pg), the primary microorganism responsible for the development of periodontitis, particularly those designed for chair-side applications, could provide substantial health benefits to patients. To address this issue, we developed a CRISPR/Cas12a-based rapid Pg detection method. Dual-gRNA and hairpin reporter strategies were employed to enhance CRISPR/Cas12a reaction efficiency.
