Published: October 2018

In order to optimize the scientific exploitation of JET (Joint European Torus) during the upcoming deuterium-tritium experiments, a set of diagnostic systems is being enhanced. These upgrades focus mainly on the experimental and operational conditions expected during tritium campaigns. It should be stressed that measurements relevant for burning plasmas are specifically targeted. Previously non-available capabilities, such as a current measurement system fully covering all poloidal field circuits, are described in detail. Instrument descriptions, performance prediction, testing, and initial commissioning results of these systems are presented.

Physicochemical properties and biological interaction of calcium silicate-based sealers - in vivo model.

Clin Oral Investig

January 2025

Department of Restorative Dentistry - Endodontics, Faculdade de Odontologia de Piracicaba, Universidade Estadual de Campinas, Piracicaba, SP, Brazil.

Objectives: To investigate volumetric changes, in vivo biocompatibility, and systemic migration from eight commercial endodontic sealer materials in paste/paste, powder/liquid, and pre-mixed forms.

Materials And Methods: The sealers AH Plus Bioceramic, AH Plus Jet, BioRoot RCS, MTApex, Bio-C Sealer, Bio-C Sealer Ion+, EndoSequence BC Sealer and NeoSEALER Flo were studied. After characterisation by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), Raman spectroscopy and X-ray diffractometry (XRD), tubes were implanted in Wistar rats' alveolar bone and subcutaneous tissues.

Background: The efficacy and safety of ensifentrine, a novel PDE3/PDE4 inhibitor, were previously evaluated in the ENHANCE-1 (NCT04535986) and ENHANCE-2 (NCT04542057) trials. Here, we present a pooled post-hoc subgroup analysis of patients according to background chronic obstructive pulmonary disease (COPD) maintenance medication regimens.

Objective: This analysis aimed to explore the efficacy and safety of ensifentrine in patients receiving long-acting muscarinic antagonists (LAMA) or long-acting beta-agonists with inhaled corticosteroids (LABA + ICS).

Dermoscopic Features of Diaper Dermatoses in Children: A Descriptive Pilot Study.

Indian Dermatol Online J

November 2024

Department of Dermatology, Venereology, and Leprosy, Gandhi Medical College, Secundarabad, Telangana, India.

Background: Diaper dermatoses broadly refer to skin disorders that occur in the diaper area. Dermoscopy is a non-invasive diagnostic tool that magnifies subsurface structures of the skin that are invisible to the unaided eye.

Aim: To identify and describe the dermoscopic features of dermatoses in the diaper area.

Precise and long-term electroanalysis at the single-cell level is crucial for the accurate diagnosis and monitoring of brain diseases. The reliable protection in areas outside the signal acquisition points at sharp ultramicroelectrode (UME) tips has a significant impact on the sensitivity, fidelity, and stability of intracellular neural signal recording. However, it is difficult for existing UMEs to achieve controllable exposure of the tip functional structure, which affects their ability to resist environmental interference and shield noise, resulting in unsatisfactory signal-to-noise ratio and signal fidelity of intracellular recordings.

Systolic blood pressure response during exercise testing in symptomatic severe aortic stenosis.

Open Heart

January 2025

Department of Cardiothoracic and Vascular Surgery, and Department of Health, Medicine and Caring Sciences, Linköping University, Linköping, Sweden.

Aims: Exercise testing remains underused in patients with aortic stenosis (AS), partly due to concerns about an exercise-induced drop in systolic blood pressure (SBP). We aimed to study the SBP response to exercise in patients with severe symptomatic AS prior to surgery and 1 year postoperatively.

Methods: Patients scheduled for aortic valve replacement due to severe symptomatic AS were enrolled at a single centre in a prospective observational cohort study.
