Children's discrimination of phonologically similar items [PDF]

The Journal of the Acoustical Society of America, 1990
Discrimination of a heard target word from phonologically similar and dissimilar items was investigated in seventeen 3.5- to 4.5-year olds and nine adults using a two-choice reaction time (RT) procedure. The target word (“little”) differed from the similar items (e.g., “lettle”) on a single acoustic-phonetic segment and from the dissimilar items (e.g.,

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

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.
