research Comparative GC-MS Based In vitro Assays of 5α-Reductase Activity Using Rat Liver S9 Fraction
The S9 fraction with GC-IDMS is effective for measuring 5α-reductase activity.
research Simultaneous determination of 30 hormones illegally added to anti-ageing functional foods using UPLC-MS/MS coupled with SPE clean-up
New method effectively detects illegal hormones in anti-aging foods.
research Screen steroid 5 alpha-reductase inhibitors in vitro by high performance liquid chromatography
The method is quick and effective for testing steroid 5 alpha-reductase inhibitors.
research Evaluation of a new X-ray fluorescent analysis technique for the creation of a Nordic hair database: elemental distributions within the root and the virgin segment of hair fibers.
The new X-ray technique allows for precise and non-destructive measurement of elements in hair, creating the first database of its kind for a specific ethnic group.
research A chemist's view of the analysis of human hair for trace elements
Analyzing trace elements in human hair is complex and needs a standardized method.
research Isolation and characterization of recombinant murine Wnt3a
Scientists successfully purified a protein called Wnt3a, which is involved in processes like hair growth, but the overall yield was low, suggesting more work is needed to improve this.
research The use of electron spin resonance techniques to determine gamma ray exposure of $\alpha$-keratin in human hair
Whole hair strands can reliably measure gamma ray exposure using ESR techniques, but samples should be analyzed quickly or stored in liquid nitrogen.
