Time-Dependent Effective Hamiltonians for Light-Matter Interactions.

In this paper, we present a systematic approach to building useful time-dependent effective Hamiltonians in molecular quantum electrodynamics. The method is based on considering part of the system as an open quantum system and choosing a convenient unitary transformation based on the evolution operator. We illustrate our formalism by obtaining four Hamiltonians, each suitable to a different class of applications.

Differential Gene Expression of Malaria Parasite in Response to Red Blood Cell-Specific Glycolytic Intermediate 2,3-Diphosphoglycerate (2,3-DPG).

Innovative strategies to control malaria are urgently needed. Exploring the interplay between sp. parasites and host red blood cells (RBCs) offers opportunities for novel antimalarial interventions.

Genetic diversity and antimicrobial resistance profiles of associated with skin and soft-tissue infections in companion animals in Lisbon, Portugal.

is the main bacterial pathogen of skin and soft-tissue infections (SSTIs) in companion animals. Antimicrobial resistance in this species is a growing public health concern. This study aims to characterize a collection of causing SSTIs in companion animals, establishing the main clonal lineages and antimicrobial resistance traits.

Exploring Efflux as a Mechanism of Reduced Susceptibility towards Biocides and Fluoroquinolones in .

is the main bacterial cause of skin and soft tissue infections (SSTIs) in companion animals, particularly dogs. The emergence of methicillin-resistant (MRSP) strains, frequently with multidrug resistance phenotypes is a public health concern. This study aimed to evaluate efflux, a resistance mechanism still poorly characterized in , as a contributor to biocide and fluoroquinolone resistance.

Occurrence and Variability of the Efflux Pump Gene across the Genus.

NorA is one of the main native MDR efflux pumps of , contributing to reduced susceptibility towards fluoroquinolones and biocides, but little is known about its variability within or its distribution and conservation among other staphylococci. We screened for sequences homologous to and found it in 61 out of the 63 species described. To the best of our knowledge, this is the first study to report the occurrence of across the genus.
