Objectives：This study investigated the antimicrobial effect and anti-inflammatory activities of PGLa-loaded TiO2 nanotube arrays (TiO2 NTs) in osteoblast-like MG-63 cells. Methods：The surface morphology and roughness of three titanium (Ti) substrates (Ti, TiO2 NTs, PGLa-loaded TiO2 NTs) were evaluated by scanning electron microscopy (SEM) and atomic force microscope (AFM). The wettability of three titanium substrates was evaluated by contact angle. Biocompatibility of PGLa-loaded TiO2 NTs were evaluated in MG-63 cells (cell adhesion, proliferation, cytoskeletal evaluation and alkaline phos...

The Limits of Language-Thought Influences Can Be Set by the Constraints of Embodiment

This paper aims to examine the asymmetric impact of oil price shocks on environmental degradation for a panel of six Gulf Cooperation Council (GCC) countries from 1996 to 2016. We use dynamic seemingly unrelated regressions (DSUR) approach that considers cross-sectional dependency to reveal the interrelations between oil price shocks and carbon dioxide (CO2) emissions. The finding shows that the positive shocks of oil prices have a statistically significant negative effect on CO2 emissions, while negative shocks of oil prices did not affect CO2 emissions. More specifically, the positive oil pr...

Scientists and policymakers have become interested in the viability of solar geoengineering as a way to manipulate the Earth’s temperature in the face of unabated global warming. This paper reports the results from a survey experiment designed to test predictions about the effects of exposure to framed messages about basic scientific research on solar geoengineering. Our findings reinforce other survey research showing that solar geoengineering is a generally unfamiliar concept, but also show that this topic has not yet become politicized. In addition, despite treatments of equal valence, we...

2Scottish Association for Marine Science (SAMS), Oban, United Kingdom This study compares the noise levels at the cold-water coral Tisler reef, before and after the closure of the border between Norway and Sweden, which occurred as a direct result of the COVID-19 pandemic. The Tisler reef is a marine protected area located under a ferry “highway” that connects Norway and Sweden. Cold-water coral reefs are recognised as being important hotspots of both biodiversity and biomass, they function as breeding and nursing grounds for commercially important fish and are essential in providing ecos...
