Structural and Computational Analysis of Pseudomonas aeruginosa DNA Gyrase Reveals Molecular Characteristics That May Contribute to Ciprofloxacin Resistance

open access: yesBiomolecules
Pseudomonas aeruginosa is considered a priority pathogen by the World Health Organization due to its resistance to antibiotics. Isolates resistant to ciprofloxacin (CPFX), a bactericide commonly used against P.

Time-lapse crystallography snapshots of a double-strand break repair polymerase in action

open access: yesNature Communications, 2017
DNA polymerase (pol) μ functions in DNA double-strand break repair. Here the authors use time-lapse X-ray crystallography to capture the states of pol µ during the conversion from pre-catalytic to product complex and observe a third transiently bound ...

Hamiltonian Structure and Integrability [PDF]

open access: yes, 1992
Publisher Summary This chapter discusses the Hamiltonian structure and integrability. The aim is to use harmonic oscillator in a general framework so that they can be carried over to other more complicated system. The chapter introduces some basic notions that describe the connection between symmetries and conserved quantities.

On integrability of Golden Riemannian structures

open access: yesTurkish Journal of Mathematics, 2013
The main purpose of the present paper is to study the geometry of Riemannian manifolds endowed with Golden structures. We discuss the problem of integrability for Golden Riemannian structures by using a f-operator which is applied to pure tensor fields.

Ironic Medications: A Narrative‐Based Psycho‐Educational Intervention to Explore Patient–Provider Communication in Adolescents With Haematological Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with haematological malignancies face significant emotional and relational challenges, often accompanied by difficulties in communicating their needs within the healthcare context. To address these issues, a narrative‐based psycho‐educational intervention based on the creation and prescription of Ironic Medications was ...

Incidence and Severity of Carboplatin‐Associated Hearing Loss in Children With Cancer Assessed by the SIOP Boston 2012 Ototoxicity Criteria

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Platinum‐based chemotherapy is known to cause severe and debilitating hearing loss, but unlike cisplatin, the true incidence of carboplatin‐induced hearing loss remains unclear. We evaluated functional hearing outcomes in children receiving carboplatin to determine the incidence and severity of ototoxicity. Procedure We identified a
