Prevalence and influencing factors of the dyadic psychological stress among patients with lung cancer and their family caregivers: a cross-sectional study.

Background: A lung cancer diagnosis has a huge impact on the psychological well-being of both patients and family caregivers. However, the current psychological stress status among dyads remains unclear. We aimed to determine the prevalence of anxiety and depression and identify the factors that influence patients with lung cancer and their caregivers.

The relationship between the variants in the 5'-untranslated regions of equine chorionic gonadotropin genes and serum equine chorionic gonadotropin levels.

Objective: An experiment was conducted to study the association between the single nucleotide polymorphisms (SNPs) in 5'-untranslated regions (5'-UTR) of equine chorionic gonadotropin (eCG) genes and the serum eCG levels.

Methods: SNPs in 5'-UTR of eCG genes were screened across 10 horse breeds, including 7 Chinese indigenous breeds and 3 imported breeds using iPLEX chemistry, and the association between the serum eCG levels of 174 pregnant Da'an mares and their serum eCG levels (determined with ELISA) was analyzed.

Results: Four SNPs were identified in the 5'-UTR of the eCGα gene, and one of them was unique in the indigenous breeds.
