A Novel Screening System to Characterize and Engineer Quorum Quenching Lactonases.

N-acyl l-homoserine lactones are signaling molecules used by numerous bacteria in quorum sensing. Some bacteria encode lactonases, which can inactivate these signals. Lactonases were reported to inhibit quorum sensing-dependent phenotypes, including virulence and biofilm.

Lived experiences of people with chronic kidney disease on maintenance dialysis: a systematic review and thematic synthesis of qualitative studies.

Aim: Chronic Kidney Disease (CKD) has emerged as a global public health concern. People with the most advanced stage of CKD require renal replacement therapies, either dialysis (the focus of this study) or a kidney transplant. Research on CKD has primarily focused on its clinical, epidemiological, and public health aspects.

Six-Month Outcomes in the Long-Term Outcomes After the Multisystem Inflammatory Syndrome in Children Study.

Importance: Multisystem inflammatory syndrome in children (MIS-C) is a life-threatening complication of COVID-19 infection. Data on midterm outcomes are limited.

Objective: To characterize the frequency and time course of cardiac dysfunction (left ventricular ejection fraction [LVEF] <55%), coronary artery aneurysms (z score ≥2.
