Objective: To design and rapidly evaluate a TaqMan assay for detecting influenza A viruses.
Methods: The probe and the primers of the assay were designed with the software packages of DNA Star and Primer Premier 5.0. Their specificity and conservation were verified through Blast in GenBank and electronic hybridization. The assay's sensitivity was compared with the standard RT-PCR.
Results: The designed primers and probe were confirmed to be very specific and conserved. The assay was 3-27 folds more sensitive than the standard RT-PCR. The RT and PCR steps could be simplified into one step.
Conclusion: The TaqMan Real-time PCR assay is specific, sensitive and easy to perform.

Environmental Exposures Associated with Enteropathogen Infection in Six-Month-Old Children Enrolled in the ECoMiD Cohort along a Rural-Urban Gradient in Northern Ecuador†.

Enteropathogens are major contributors to mortality and morbidity, particularly in settings with limited access to water, sanitation, and hygiene infrastructure. To assess transmission pathways associated with enteropathogen infection, we measured household environmental conditions and assayed 22 enteropathogens using TaqMan Array Cards in stool samples from 276 six-month-old children living in communities along a rural-urban gradient in Northern Ecuador. We utilized multivariable models, risk factor importance, and distance-based statistical methods to test factors associated with infection.

Background And Aims: Mounting evidence have implicated that rs1801131 and rs1801133, located in the Methylenetetrahydrofolate reductase (MTHFR) gene, may emerge as novel biomarkers for coronary artery disease (CAD). The Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score is also an appropriate predictor for revascularization strategy in patients with complex CAD. The aim of this study is to investigate the correlation between rs1801131 and rs1801133 with the severity of coronary lesions in patients with ST‑Elevation Myocardial Infarction (STEMI) and Non‑ST‑Elevation Myocardial Infarction (NSTEMI) based on the SYNTAX score.

Adenoviruses are a concern for pigeon breeders due to their impact on animal health. Furthermore, they have been studied for nearly five decades and are one of the most studied viruses in pigeons. However, the number of complete genomic sequences of pigeon-infecting adenoviruses available is very low, and the pathogenic effect of these viruses on pigeons is still yet to be thoroughly explored.

Article Synopsis
- Hepatitis B virus (HBV) is a major global health concern linked to liver disease and cancer, with research focusing on genetic factors that affect its evolution.
- Recent studies highlighted the ECM1 gene, specifically two polymorphisms (rs3834087 and rs3754217), which may influence HBV pathogenesis, particularly in an African cohort analyzed in this research.
- The study found that the heterozygous genotype of rs3754217 appears to protect against chronic hepatitis, suggesting that certain genetic variations may impact the severity of the disease in infected individuals.

Gallstones are among the most frequent hepatobiliary conditions. Although in most cases, they remain asymptomatic, they can cause complications and, in such cases, invasive treatments like endoscopic retrograde cholangiography (ERC) or cholecystectomy are required. Here, we present the results of genetic testing of a single family with a high incidence of symptomatic gallstones and cholestatic liver phenotypes.
