Cadmium is a toxic metal found ubiquitously throughout the world. Our study evaluated whether cadmium exposure was associated with telomere length in 73 female university students. Determination of telomere length was performed by quantitative polymerase chain reaction using DNA in blood. Urinary cadmium concentration was measured by inductively coupled plasma mass spectrometry. The students' physiological attributes and lifestyle were surveyed by means of a self-administered questionnaire. The geometric mean of urinary cadmium concentration was 0.312 μg/g creatinine, which was lower than the levels previously reported for Japan. Urinary cadmium concentration was not significantly associated with telomere length, though the exposure level of the present subjects was similar to that of previous study subjects which found significantly negative associations. It is possible that other factors affected telomere length in this study population.

Atrial fibrillation (AF) is the most common form of cardiac arrhythmia, the prevalence of which increases with age. Slowing down senescence is one of the urgent challenges of modern science. Therefore, it is important to identify individuals with markers of premature cellular senescence for further development of pharmacological agents capable of slowing it.

Polyploidy, a conserved mechanism involved in normal development and tissue homeostasis, plays a paradoxical role in cancer by facilitating both tumor progression and therapeutic vulnerability. Although polyploidization may confer survival advantages to cancer cells, its controlled induction could represent an effective anticancer strategy. Aurora B kinase, a critical regulator of mitosis, plays a pivotal role in ensuring chromosomal integrity and preventing polyploidy.

The mechanism underlying the effects of Polycyclic aromatic hydrocarbons (PAHs) on missed abortion (MA) remains unclear. This study explored the relationship between PAHs exposure, telomere length (TL), metabolizing enzyme gene polymorphism, and MA in a case-control study with 253 pregnant women. A competitive enzyme-linked immunosorbent assay (ELISA) was used to quantify PAH-DNA adducts.

Background: Telomere length (TL) is a valuable marker of aging and stress that reflects both genetic and environmental influences. Quantitative PCR (qPCR) TL measurement is a powerful and cost-effective assay, especially in population studies with limited quantities of source material. Nevertheless, collecting and transporting high-quality blood samples can be logistically challenging, and research suggests that several preanalytical and analytical factors can influence the reliability and precision of the qPCR assay.
