Background: Human cytomegalovirus (CMV) has been linked to the pathogenesis of elevated arterial blood pressure (BP). Our study aimed to determine the association between anti-CMV titers and arterial BP in the Kazakh and Han Chinese populations.

Material And Methods: Kazakh and Han (n = 800 each) (age, ≥18 years) subjects from Xinjiang, China were examined for anti-CMV immunoglobulin (Ig)G titers using a commercially available enzyme-linked immunosorbent assay (ELISA) kit. The highest anti-CMV titer tertiles determined within gender and ethnicity groups were compared against the two lower tertiles and seronegative samples.

Results: Multivariate linear regression analysis revealed that anti-CMV titers were independent determinants for elevated systolic (p = 0.006) BP in Kazakh women and inversely associated with systolic (p = 0.004) and mean arterial (p = 0.019) BP in Han women.

Conclusion: The association between CMV infection and/or resulting immune response and BP elevation differed by sex and ethnicity. In Kazakh women, they were associated with elevated BP and the opposite was true among Han women.

causes bovine mastitis, reduces milk quantity and quality, and is often resistant to antimicrobials. Selenomethionine (SeMet) is a form of selenium, which reduces reactive oxygen species (ROS)-mediated apoptosis and intramammary infections. However, the protective effects of SeMet on -infected bovine mammary epithelial cells (bMECs) are unclear.

Department of Forensic Medicine, Hainan Provincial Academician Workstation (Tropical Forensic Medicine), Hainan Province Tropical Forensic Engineering Research Center, Hainan Medical University, Haikou, China.

Article Synopsis
  • The study aimed to explore the forensic characteristics and genetic relationships of the Hainan Han population by evaluating 23 short tandem repeat (STR) loci from 2971 individuals.
  • Findings showed high genetic similarity between the Hainan Han and other nearby Han populations, while there were significant genetic differences when compared to various ethnic minorities, especially in Yunnan and Xinjiang regions.
  • The 23 STR loci were highly polymorphic, making them effective for forensic identification and paternity testing within the Hainan Han population, reflecting how genetic diversity relates to ethnic origin and geographical location.
