research Determination of candesartan in human plasma by HPLC-MS-MS
A reliable method was developed to measure candesartan in human plasma.
research Workplace Drug Testing Using Hair Samples
Hair testing is a reliable method for detecting workplace drug use when done with proper sample preparation and confirmation.
research Techniques for the discovery and evaluation of drugs against alopecia
We need better treatments for hair loss, and while test-tube methods are helpful, they can't fully replace animal tests for evaluating new hair growth treatments.
research Biochemical Insights and Clinical Applications of Ischemia-Modified Albumin in Ischemic Conditions
Ischemia-modified albumin can help diagnose ischemic conditions early, but better detection methods are needed.
research Revisiting hyper- and hypo-androgenism by tandem mass spectrometry
The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.
research The quantification of reproductive hormones in the hair of captive adult brown bears and their application as indicators of sex and reproductive state
Measuring reproductive hormones in brown bear hair could help identify their sex and reproductive state, but better collection methods or lab techniques are needed.
research Isolating subpopulations of human epidermal basal cells based on polyclonal serum against trypsin-resistant CSPG4 epitopes
The research found a way to identify and study skin cells with stem cell traits, revealing they behave differently in culture and questioning current stemness assessment methods.
