Background: In this study, we developed a SYBR Green-based real-time PCR assay for the detection of sheep pox virus using a plasmid construct carrying one of the highly conserved genes encoding the virion envelope protein (P32) as a template.
Results: The method was demonstrated to be highly sensitive, allowing a precise SPV DNA quantitation over a range of nine orders of magnitude (from 101 to 109 copies of standard DNA). Then, specimens from SPV suspected sheep were analyzed by conventional gel-based PCR, real-time PCR and sequence analysis.
Conclusion: Comparison between these different techniques revealed that real-time PCR is more sensitive than conventional gel-based PCR, allowing detection low viral titers of SPV in infected sheep.

The effect of non-functionalized polystyrene nanoparticles (PS-NPs) with diameters of 29, 44, and 72 nm on plasmid DNA integrity and the expression of genes involved in the architecture of chromatin was investigated in human peripheral blood mononuclear cells (PBMCs). The cells were incubated with PS-NPs at concentrations ranging from 0.001 to 100 µg/mL for 24 hours.

Porcine reproductive and respiratory syndrome virus (PRRSV) is an RNA virus that induces reproductive disorders in sows and respiratory diseases in growing pigs. Recently, the NADC34-like strain of PRRSV has become more prevalent, with outbreaks occurring across pig farms in China. However, a reliable diagnostic method for the clinical detection of this strain has been absent.

COVID-19 variants continue to infect thousands of people even though the end of the pandemic was announced on May 11, 2023. Nextstrain CoVariants (CoVariants) genomic databases provide detailed information about more than 31 variants of COVID-19 viruses that have been identified through genomic sequencing, showing the mutations they carry. Mutated viruses may yield a negative result for a gene target using a PCR test that has a positive COVID-19 test result.

Background: Insulinoma, the most common type of pancreatic endocrine tumor, frequently induces hypoglycemia due to persistent hyperinsulinemia. Although Mi-Lnc70 expression progressively increases during pancreatic maturation in mice, the biological role of Mi-Lnc70 in pancreatic β cells remains elusive.
Aim: This study was designed to investigate the role of LncRNA-Mi-Lnc70 in the mouse pancreatic β-cell line MIN6.

Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs. Xenotransplantation of chicken PGCs can achieve germline transmission. However, there are still challenges in obtaining many PGCs from endangered birds in vitro.
