Supercell calculations in the reduced Hartree-Fock model for crystals with local defects

open access: yes, 2016
In this article, we study the speed of convergence of the supercell reduced Hartree-Fock~(rHF) model towards the whole space rHF model in the case where the crystal contains a local defect.

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

open access: yesMolecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

The Defect Sequence for Contractive Tuples

open access: yes, 2012
We introduce the defect sequence for a contractive tuple of Hilbert space operators and investigate its properties. The defect sequence is a sequence of numbers, called defect dimensions associated with a contractive tuple.

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Preparation of reduced graphene oxide supported palladium nanocomposites for amperometric sensing of NADH

open access: yesInternational Journal of Electrochemical Science, 2020
Reduced graphene oxide-supported palladium nanocomposites (Pd-rGO) were synthesized by an in situ chemical reduction method. The composite nanomaterials have excellent conductivity and catalytic ability due to the synergistic effect of the two components.

Class IIa HDACs forced degradation allows resensitization of oxaliplatin‐resistant FBXW7‐mutated colorectal cancer

open access: yesMolecular Oncology, EarlyView.
HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

Eigenfunction scarring and improvements in $L^{\infty}$ bounds

open access: yes, 2018
We study the relationship between $L^\infty$ growth of eigenfunctions and their $L^2$ concentration as measured by defect measures. In particular, we show that scarring in the sense of concentration of defect measure on certain submanifolds is ...

Strength through diversity: how cancers thrive when clones cooperate

open access: yesMolecular Oncology, EarlyView.
Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.

Assessing the clinical application value of SNP-array in fetal central nervous system malformations

open access: yesHuman Genomics
Background Single nucleotide polymorphism array (SNP-array) has been introduced for prenatal diagnosis. This study aims to evaluate the clinical utility of SNP-array in the prenatal central nervous system (CNS) malformations.

Verifying the Usefulness of Pulmonary Blood Flow Studies in the Correction of Pulmonary Atresia and Ventricular Septal Defect with Major Aortopulmonary Collateral Arteries

open access: yesCardiology Research and Practice, 2021
Objective. We retrospectively analyzed the surgical results of pulmonary blood flow studies to guide ventricular septal defect (VSD) closure in the correction of pulmonary atresia and ventricular septal defect with major aortopulmonary collateral ...
