Standardization of the use of opsonized zymosan as stimulus in the 1,2,3-dihydrorhodamine technique for the assessment of neutrophil respiratory burst.

Introduction: Chronic granulomatous disease is a defect in phagocytosis due to deficiency of gp91phox, p22phox, p47phox, p40phox, and p67phox (classic form of the disease). Recently, EROS and p40phox deficiency were described as responsible for the non-classical form of the disease. The 1,2,3-dihydrorhodamine oxidation technique, with phorbol-12-myristate-13-acetate as a stimulus, is performed to diagnose the classic chronic granulomatous disease.

Multi-omic signatures of host response associated with presence, type, and outcome of enterococcal bacteremia.

Unlabelled: Despite the prevalence and severity of enterococcal bacteremia (EcB), the mechanisms underlying systemic host responses to the disease remain unclear. Here, we present an extensive study that profiles molecular differences in plasma from EcB patients using an unbiased multi-omics approach. We performed shotgun proteomics and metabolomics on 105 plasma samples, including those from EcB patients and healthy volunteers.

The One-step No-prep technique for non-invasive full-mouth rehabilitation of worn dentition using PICN CAD-CAM restorations: Up to 9-year results from a prospective and retrospective clinical study.

Objectives: To report up to 9-year results of a prospective and retrospective study on non-invasive full-mouth rehabilitation of worn dentition with PICN CAD-CAM restorations using the One-Step No-Prep technique. The secondary objective is to evaluate the influence of restoration thickness on fracture of restorations.

Methods: A total of 580 Vita Enamic restorations (218 anterior and 362 posterior; 260 monoblock (MO) and 320 multiColor (MC)) in 24 patients were clinically evaluated once a year (up 9 months to 9 years) according to FDI criteria.

Recent developments in antimicrobial small molecule quaternary phosphonium compounds (QPCs) - synthesis and biological insights.

The development and characterization of quaternary phosphonium compounds (QPCs) have long benefitted from their incorporation into a cornerstone reaction in organic synthesis - the Wittig reaction. These structures have, more recently, been developed into a wide variety of novel applications, ranging from phase transfer catalysis to mitochondrial targeting. Importantly, their antimicrobial action has demonstrated great promise against a wide variety of bacteria.

Heart Rate Variability Does Not Predict Recurrence of Apnoea of Prematurity After Ceasing Caffeine Therapy: A Prospective Cohort Study.

Aim: We evaluated whether sample entropy of heart rate time series could serve as a biomarker for guiding caffeine cessation in preterm infants treated for apnoea of prematurity (AOP). We also assessed associations of sample entropy with weeks of gestation, clinical morbidity, AOP frequency and caffeine reinitiation.

Methods: We conducted a prospective single-centre study at the University Children's Hospital Basel, Switzerland, from July 2019 to June 2020.
