The prevalence of dental anomalies among Saudi Population in Makkah, Saudi Arabia.

Background: Morphological and structural abnormalities are common dental anomalies. Identifying DA and determining their prevalence can play an important role in reducing the risk of surgical intervention and improving occlusion, leading to successful dental treatments. Thus, this study aimed to determine the prevalence of DA using panoramic radiographs (OPG) in Makkah, Saudi Arabia according to gender.

Core and surface structure and magnetic properties of mechano-synthesized LaFeO nanoparticles and their Eu-doped and Eu/Cr-co-doped variants.

The core and surface structure, and magnetism of mechano-synthesized LaFeO nanoparticles (30-40 nm), Eu-doped (LaEuFeO), and Eu/Cr co-doped (LaEuFeCrO) are reported. Doping results in a transition from the O'-type to the O-type distorted structure. Traces of reactants, intermediate phases, and a small amount of Eu ions were detected on the surfaces of the nanoparticles.

Immune reconstitution and survival, following hematopoietic stem cell transplantation in Omani patients with inborn errors of immunity.

Background: Hematopoietic stem cell transplantation (HSCT) is a curative treatment for certain inborn errors of immunity.

Methods: A 17-year retrospective cohort study was conducted on 40 immunodeficient patients who underwent HSCT.

Results: The median age at transplant was 11.
