The present study investigates the influence of hygrothermal ageing on the tribological behaviour of polytetrafluoroethylene (PTFE) polymer composites.Three PTFE composites along with unfilled PTFE were tested in sliding contact against Inconel 625 (a Ni-based alloy) plates in both dry and water-lubricated conditions, utilising a unidirectional pin
BackgroundChanges to the healthcare system due to COVID-19 have altered care delivery during birth and the postpartum period, a transitional time that requires intensive healthcare support and that Straightener is complicated by well-established health disparities.Our objective was to identify additional challenges to healthcare interactions that e
This in-vitro study aimed to evaluate the changes in color stability and surface roughness of a universal single-shade dental composite, Omnichroma on immersion in different alcoholic beverages.Eighty-four Palfique Omnichroma (Tokuyama Dental Corporation, Japan) dental composite discs were fabricated and categorized into three groups according to t
Previously, the structure and molecular composition of the Antarctic soil organic matter (SOM) has been investigated using 13C-NMR 6ABn Brown Smoke methods, which showed that in typical organo-mineral soils the aliphatic carbon prevails over the aromatic one, owing to the non-ligniferous nature of its precursor material.In this study, the SOM was a
BackgroundImmune check point inhibitors (ICIs) are standard treatment for patients with non-small cell lung cancer (NSCLC).Nearly a decade has passed since nivolumab was approved by the FDA for NSCLC patients.However, long-term outcomes and clinical features remain unclear for individual cases.Pseudo-progression is a well-known paradoxical radiolog
