Assessment of a New CT Detector and Filtration Technology: Part 1 - X-ray Beam Characterization and Radiation Dosimetry.

Purpose: This study evaluated beam quality and radiation dosimetry of a CT scanner equipped with a novel detector and filtration technology called PureVision Optics (PVO). PVO features miniaturized electronics, a detector cut with microblade technology, and increased filtration in order to increase x-ray detection and reduce image noise.

Methods: We assessed the performance of two similar 320-detector CT scanners: one equipped with PVO and one without.

Human airway epithelium controls infection via inducible nitric oxide synthase.

Introduction: Airway epithelial cells play a central role in the innate immune response to invading bacteria, yet adequate human infection models are lacking.

Methods: We utilized mucociliary-differentiated human airway organoids with direct access to the apical side of epithelial cells to model the initial phase of respiratory tract infection.

Results: Immunofluorescence of infected organoids revealed that invades the epithelial barrier and subsequently proliferates within the epithelial space.

Long-term storage of pink pepper essential oil microencapsulated by chickpea protein/pectin complexes: volatile release, antioxidant and antimicrobial activities.

Pink pepper essential oil was microencapsulated with chickpea protein (CP) and chickpea protein/pectin (CP-HMP) by spray drying. The reconstitution and storage properties of the powders were evaluated after drying. The impact of microencapsulation in the volatiles release, antioxidant and antimicrobial activity of oil was evaluated during 135 days of storage.

Machine learning prediction of unexpected readmission or death after discharge from intensive care: A retrospective cohort study.

Background: Intensive care units (ICUs) harbor the sickest patients with the utmost needs of medical care. Discharge from ICU needs to consider the reason for admission and stability after ICU care. Organ dysfunction or instability after ICU discharge constitute potentially life-threatening situations for patients.
