research Analytical interference of biotin
Taking too much biotin can mess up blood test results, which might lead to wrong diagnoses and treatments.
research Synthesis of 11α-hydroxyprogesterone hartens
Researchers successfully made new compounds for hormone level tests, but one attempt led to an unexpected product, correcting a past error.
research Photoinduced formation of thiols in human hair
UV exposure damages hair, increasing thiols and altering protein structure.
research Human hair keratin responds to oxidative stress via reactive sulfur and supersulfides
Human hair strength and health are linked to sulfur compounds that can be reduced by stress but improved with sulfur supplements.
research Heterozygous 21‐hydroxylasedeficiency as a cause of hyperandrogenism
A woman's hyperandrogenism was caused by a genetic mutation leading to non-classic adrenogenital syndrome.
