Circulating tumor plasma cells quantification in newly diagnosed transplant ineligible real world multiple myeloma patients: Comparison of single‐platform flow cytometry versus next generation flow

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Circulating tumor plasma cells (CTCs) at diagnosis are independent prognostic markers in newly diagnosed multiple myeloma (NDMM). Flow cytometry (FC) enables sensitive and cost‐effective CTC quantification, but prognostic cut‐offs vary across studies.

An Investigation Into the Yields of 3,4‐Methylenedioxyphenyl‐2‐propanone (MDP2P) From Glycidate Pre‐Precursors

Drug Testing and Analysis, EarlyView.
Hydrolysis of the glycidate pre‐precursors MMDMG and EMDMG was evaluated for MDP2P production. Acid hydrolysis of MMDMG (HCl, 100°C, 18 h) yielded the highest MDP2P recovery (79%), whereas base hydrolysis produced only slightly lower yields (73%), demonstrating both pathways are effective routes to this key MDMA precursor.

Population Pharmacokinetics and Detection Times of Betamethasone After Intravenous, Intramuscular, and Intranasal Jet Administration of Betamethasone Sodium Phosphate in Horses

Drug Testing and Analysis, EarlyView.
Betamethasone concentrations in 20 horses from Japan and Germany following IV, IM, and INJ administration of betamethasone phosphate were analyzed using population pharmacokinetic modeling. For IV administration of 0.04 mg/kg q24 h, IPC and IUC were 0.012 and 0.31 ng/mL, respectively; the IUC approximated the IFHA urine ISL (0.20 ng/mL).
