Effective filtering of modal curvatures for damage identification in beams [PDF]

, 2017
In this work, we investigate the effectiveness of a damage identification technique recently proposed in [1] and assess how it is affected by the number and position of the sensors used.

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Osmotic disruption of chromatin induces Topoisomerase 2 activity at sites of transcriptional stress

Nature Communications
Transcription generates superhelical stress in DNA that poses problems for genome stability, but determining when and where such stress arises within chromosomes is challenging. Here, using G1-arrested S.

PARP3 is a sensor of nicked nucleosomes and monoribosylates histone H2BGlu2

Nature Communications, 2016
Chromosomal single-strand DNA breaks occur frequently and require repair to avoid disease outcomes. Here, the authors show that in bird cells, PARP3 accelerates this repair, and use structural biology and cell biology techniques to reveal details of the ...

A sophisticated mechanism governs Pol ζ activity in response to replication stress

Nature Communications
DNA polymerase ζ (Pol ζ) plays an essential role in replicating damaged DNA templates but contributes to mutagenesis due to its low fidelity. Therefore, ensuring tight control of Pol ζ’s activity is critical for continuous and accurate DNA replication ...

Animal experiments and network pharmacology to explore the anti-inflammatory mechanism of dapagliflozin in the treatment of polycystic ovary syndrome

Gynecological Endocrinology
Background Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder associated with chronic low-grade inflammation of the ovary. Sodium glucose co-transporter 2 (SGLT2) inhibitors are a class of antidiabetic drugs that can reduce the

Protein Phosphatase 1 Recruitment by Rif1 Regulates DNA Replication Origin Firing by Counteracting DDK Activity

Cell Reports, 2014
The firing of eukaryotic origins of DNA replication requires CDK and DDK kinase activities. DDK, in particular, is involved in setting the temporal program of origin activation, a conserved feature of eukaryotes.

Molecular basis for DNA repair synthesis on short gaps by mycobacterial Primase-Polymerase C

Nature Communications, 2020
Mycobacteria Prim-PolC performs short gap synthesis following removal of lesions during excision repair. Here the authors resolve crystal structures of pre- and post-catalytic Prim-PolC complexes bound to gapped DNA substrates to define its mechanism.

Mechanisms of sensorineural cell damage, death and survival in the cochlea. [PDF]

, 2015
The majority of acquired hearing loss, including presbycusis, is caused by irreversible damage to the sensorineural tissues of the cochlea. This article reviews the intracellular mechanisms that contribute to sensorineural damage in the cochlea, as well ...
