Article Synopsis
- The study investigates how the structure and growth potential of the proximal tibia compares to the distal femur in children during their growth spurt using diffusion tensor imaging (DTI).
- It involved 108 healthy children, analyzing DTI parameters like tract number, length, and volume, and finding that the proximal tibial tracts were more numerous in the central area while distal femoral tracts were more peripheral.
- The results indicated that tibial tract volume was significant during peak height gain, showing that the tibia's growth patterns occur earlier than those of the femur.
Sickle cell anemia (SCA) results from a mutation in the -globin gene, leading to the production of mutant hemoglobin, known as hemoglobin S (HbS). Despite being a genetic disorder, the phenotype of SCA can be influenced by the level of fetal hemoglobin (HbF), which is associated with beta S-globin haplotypes. In this study, we conducted newborn screening (NBS) using samples collected from umbilical cord blood in two hospitals on Santiago Island, Cape Verde.

Phosphogypsum (PG) is a solid by-product of the phosphate industry, rich in contaminants and produced in large quantities. Raw materials and stabilized specimens, consisting of bentonite-lime-PG mixtures, were characterized by mineralogical, microstructural, chemical, alpha-particle, and gamma-ray spectrometry analysis before hydration and after hardening. Compressive strength and leaching tests were performed on hardened specimens.
