A rare, the uncommon, case of multiple invasive cervical resorption (MICR) with subsequent arrest of the resorption involving eight teeth of the mandible (tooth 46 to tooth 32) is presented. This case is noteworthy because of the characteristics of its clinical evolution. There have only been a few cases in the literature were found presenting involvement of such a large number of teeth. Furthermore, no reports on cases of MICR with arrest of the resorption, as described in this report, were found.

Information on the age of vertebrate species such as sea turtles is crucial for planning management and conservation actions. The age of sea turtles has been estimated by skeletochronological analysis using skeletal growth marks in different bones. This study focused on the consistency of the number of visible lines of arrested growth (LAG) observed from the humerus and phalanx bone used for age estimation in Chelonia mydas and Caretta caretta.

Mechanical unloading causes bone loss, but it remains unclear whether disuse-induced changes to bone microstructure are permanent or can be recovered upon reloading. We examined bone loss and recovery in 17 astronauts using time-lapsed high-resolution peripheral quantitative computed tomography and biochemical markers to determine whether disuse-induced changes are permanent. During 6 months in microgravity, resorption was threefold higher than formation.

Calciphylaxis, also known as calcific uremic arteriolopathy (CUA), is a rare disorder with many unknown treatment and diagnostic aspects. It is characterized by calcification and thrombosis of small blood vessels. This disease leads to progressive skin calcification, necrotizing ulcers, and infections and is associated with a high mortality rate.

Prostate cancer, as one of the most prevalent malignant tumors in men, seriously affects the prognosis and survival of patients due to its extremely high rate of bone metastasis. This study investigated the effect of Polyphyllin VI (PPVI) on metastatic bone disease for the first time in prostate cancer, focusing on its impact on osteoclast and tumor cell. In vitro studies utilized TRAP staining, ghost pen cyclic peptide staining, and bone resorption assays to evaluate the differentiation and function of receptor activator of nuclear factor-κB ligand (RANKL) induced and RM-1 conditional medium (CM) induced osteoclasts.
