The impact of geopolitical risk on CO emissions inequality: Evidence from 38 developed and developing economies.

This paper analyses the impact of geopolitical risk on carbon dioxide (CO) emissions inequality in the panel dataset of 38 developed and developing economies from 1990 to 2019. At this juncture, the empirical models control for the effects of globalisation, capital-labour ratio, and per capita income on CO emissions inequality. The panel cointegration tests show a significant long-run relationship among the related variables in the empirical models.

A Snapshot of Potentially Inappropriate Prescriptions upon Pediatric Discharge in Oman.

Background: Identifying and quantifying potentially inappropriate prescribing (PIP) practices remains a time-consuming and challenging task, particularly among the pediatric population. In recent years, several valuable tools have been developed and validated for assessing PIP. This study aimed to determine the prevalence of PIP and related risk factors in pediatric patients at a tertiary care hospital in Oman.

Bioactive and Elastic Nanocomposites with Antimicrobial Properties for Bone Tissue Regeneration.

Bone injuries represent a major challenge in the medical field. The commonly used treatments for bone regeneration rely on the use of bone grafts that are usually associated with complications such as donor site morbidity, disease transmission, high cost, and lack of availability. Bone tissue engineering has become a golden solution for the repair of bone injuries by regenerating the damaged biological tissues using biocompatible scaffolds.

Ni-free, built-in nanotubular drug eluting stents: Experimental and theoretical insights.

Stents used for cardiovascular applications are composed of three main elements; a metal, polymer coating and the specific drug component. Nickel-based metals and polymer coatings currently used in the stent market have increased the recurrence of in-stent restenosis and stent failure due to inflammation. In this study, a Ti-8Mn alloy was used to fabricate a nanostructured surface that can be used for drug eluting stents to overcome the hypersensitivity of metals that are currently used in stent making as well as introducing a new built-in nano-drug reservoir instead of polymer coatings.
