Osteopenia is a common bone disorder that is the most prevalent underlying cause of fractures. One of the causes of secondary osteopenia is spondyloarthritis. The rate of bone loss in patients with spondyloarthritis is relatively high in the early stages of the disease. Objectives: This study is evaluated the prevalence and risk factors of low bone mineral density by Dual Energy X-ray Absorptiometry (DEXA) in spondyloarthritis.

In this study, spinel ferrite nanoparticles CoFe2-xLaxO4 (x = 0, 0.025, and 0.05) were successfully synthesized via a simple co-precipitation method using a 5% NaOH solution as a precipitating agent. The physicochemical properties of the materials, annealed at 850 °C for one hour, were characterized using powder X-ray diffraction (PXRD), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), and vibrating-sample magnetometry (VSM) at room temperature.

This paper presents, we present the structure, magnetic properties, and magnetocaloric effect of the Fe81-xCrx+4B2Zr10Nd3 (x = 0, 1, 2, and 3) alloy ribbons. The alloy ribbons were prepared by using the meltspinning method. Structural analysis by X-ray diffraction shows that the obtained alloy ribbons are almost amorphous.
