Oxide materials such as Al2O corundum has a great influence on the mechanical and oxidation properties of refractory or refractory materials. In this paper, the effect of Al2O3 powder density, apparent porosity, linear shrinkage, and oxidation resistance of SiC composite refractory materials is investigated. Meanwhile, the compressive and flexural strengths were investigated before and after he...

Lamotrigine (LTG), a newly developed antiepileptic drug (AED), is efficacious in treating refractory epilepsy. This study was designed to evaluate the efficacy and safety of LTG as add-on therapy in 40 children with refractory epilepsy. The trial was an open-labeled prospective study in children with drug-resistant epilepsy aged

Cardiac disease is the main cause of death in both forms of thalassemia; thalassemia major (TM) and thalassemia intermedia (TI). Pulmonary hypertension (PH) is one of the cardiopulmonary morbidities with high mortality that, if not treated, may trigger right-sided heart failure and premature death. PH is defined as a mean pulmonary artery pressure of ≥25 mmHg at rest or ≥30 mmHg during exercise...
