Minimum Tillage Vegetable Crop Production in California [PDF]
, 2004 Author(s): Mitchell, Jeffrey; Jackson, Louise; Miyao, Gene | Abstract: Tillage operations in vegetable production represent time, energy, equipment, and labor costs that can comprise more than 25% of preharvest production expenses. Reduced-tillage, or minimum-tillage, production systems for vegetables have been developed to control costs and optimize ...

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‐
