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.

Polynomials with Real Zeros and Compatible Sequences

The Electronic Journal of Combinatorics, 2012
In this paper, we study polynomials with only real zeros based on the method of compatible zeros. We obtain a necessary and sufficient condition for the compatible property of two polynomials whose leading coefficients have opposite sign. As applications, we partially answer a question proposed by M. Chudnovsky and P. Seymour in the recent publication [

On Estimation of Zero-Sequence Impedances of Parallel Transmission Lines from Fault Data [PDF]

The problem of estimating zero-sequence parameters of a parallel transmission line from fault data is considered. This paper analytically demonstrates that the zero-sequence impedances of a parallel transmission line are not, in general, attainable using

Zero-Sequence Current Reduction Technique for Electrical Machine Emulators With DC Coupling by Regulating the SVM Zero States

, 2022
In this article, a new zero-sequence current suppression technique for electrical machine emulators with reduced component count is proposed. The proposed control scheme is implemented by properly regulating the zero states in space vector modulation ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

High-impedance faulty feeder detection for cross-country faults in distribution networks based on zero-sequence active power regulation

International Journal of Electrical Power & Energy Systems
The weak characteristics of high-impedance faults and the complex attributes of cross-country faults make faulty feeder detection of cross-country high-impedance faults difficult in medium-voltage networks. This paper deduces the zero-sequence equivalent

Three‐phase isolated power transformer based novel structure for power distribution system and new theoretical/practical judgement criteria in detecting high‐impedance earth faults

IET Renewable Power Generation, 2023
Single phase‐earth faults are the most frequent faults likely to occur but hard to identify in distribution system, especially in a neutral un‐effectively grounded system.

On the zeros of sequences of polynomials

Journal of Approximation Theory, 1990
The author presents a generalization of Blatt, Staff and Simkani theorem on the limit distribution of zeros of sequences of polynomials. The advantage of the generalized theorem lies in the fact that it does not mention the highest coefficient of the polynomials.

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...
