Scientists Develop LCMS Method for Poisonous Plant

September 4, 2013 2:07 pm | by Kew Gardens | News | Comments

When chemists examined the scientific literature on yew wood chemistry, they found that reports on taxines, particularly taxine B, in heartwood of yew were ambiguous. They developed an LCMS method to detect and handle enquiries.                           

CDC Warns of New Designer Drug

September 4, 2013 12:33 pm | by CDC | News | Comments

Acetyl fentanyl overdose deaths have recently been confirmed in Pennsylvania. If states observe clusters or increases in illicit opioid-related overdoses above expected levels, acetyl fentanyl could be involved. CDC encourages laboratories to use an ELISA test to screen specimens from suspected illicit, nonpharmaceutical opioid overdose deaths. If an ELISA test is positive for fentanyl, CDC recommends confirmatory testing by GCMS.
