THE METHODOLOGY OF CIRCUIT CONSTRUCTION OF THE ANALOG VALUE CONVERTER IN THE TIMEFRAME

Измерение, мониторинг, управление, контроль, 2023
Background. Most modern digital voltmeters use an analog-to-digital converter (ADC) of the time-pulse type with two-stage integration, which takes place in two stages – integration and counting.

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

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.
