Structural modification of the alkylquinoline cell-cell communication signal, HHQ, leads to benzofuranoquinolines with anti-virulence behaviour in ESKAPE pathogens.

Microbial populations have evolved intricate networks of negotiation and communication through which they can coexist in natural and host ecosystems. The nature of these systems can be complex and they are, for the most part, poorly understood at the polymicrobial level. The Pseudomonas Quinolone Signal (PQS) and its precursor 4-hydroxy-2-heptylquinoline (HHQ) are signal molecules produced by the important nosocomial pathogen .

Organizational flow chart of home care for children with special health care needs.

Objective: To develop a workflow protocol for Home Care (HC) services in the HC2 modality for children with special health care needs (CSHCN) in the state of Parana.

Method: Quantitative, descriptive, exploratory, multiple case studies. Data was collected with professionals from the eight home care services in Parana.

Thrombin generation and thromboelastometry in monitoring the in-vitro reversal of warfarin: a comparison between 3-factor and 4-factor prothrombin complex concentrates.

: The efficacy of three-factor prothrombin complex concentrates (PCCs) in the reversal of vitamin K antagonists is still a matter of debate. We compared the 'in-vitro' effect of three PCCs (one three-factor and two four-factor) on international normalized ratio (INR), thrombin generation and thromboelastometry of patients at different degrees of anticoagulation with vitamin K antagonist. We tested three concentrations of PCC (0.

Efficient and low-cost alternative of lipase concentration aiming at the application in the treatment of waste cooking oils.

In this study, we evaluated the concentration of lipases from Aspergillus niger using efficient and low-cost methods aiming at application in the treatment of waste cooking oils. The change in ionic strength of the medium by the addition of salt and precipitation with ethanol increased the specific activity from 2.90 to 28.
