Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

No-tillage Corn Weed Management
, 2002 Materials and Methods The crop rotation was corn following soybean. Crop residue was 95–100% at planting. Fertilization included 100 lb/A actual N applied as 28% urea ammonium nitrate dribble banded. A randomized complete block design with three replications was used. Herbicides were applied in 20 gal. water/acre.
