January 2017 in “Folia biologica” This study identified two single-nucleotide polymorphisms and three haplotypes in the KRTAP7-1 gene across yak, taurine, and zebu cattle, with the BOVIN-KRTAP7-1*A haplotype most prevalent.
September 2023 in “Scientific reports” This study observed that testosterone concentrations in hair segments show some stability over time, but are influenced by factors like sebum integration, hair washing frequency, and individual hair growth rates.
July 2022 in “Research Square (Research Square)” This study found that hair testosterone concentrations show some consistency over time, but factors like hair washing and individual growth rates influence these levels, suggesting the need for careful sampling and analysis adjustments.
