The study included detection of the sites of ossification centers and their sequence of appearance in the forelimb bones of indigenous sheep fetuses by using double staining method with younger specimens and radiography or maceration methods with old specimens, as well as, histological study with some ages. The results showed that the primary ossification centers of the forelimb in indigenous s...

BACKGROUND Legal age estimations of living individuals are gaining increasing importance for radiologists involved in delivering expert opinions. The present study aimed to assess the correlation between chronological age and apophyseal centers distance from pelvic bone. MATERIALS AND METHODS This was a cross-sectional study carried out on 2013. Subjects were chosen from 15 to 25 years old pe...

Endometrial calcification along with ossification is an uncommon clinical entity. Most of the cases are asymptomatic or present with secondary infertility. Endometrial ossification associated with repeated abortions has been reported very infrequently. Here we report a case of endometrial calcification with ossification  due to retained fetal bony tissue in a 38 year old symptomatic female havi...

Two subsequent different types of bone formation, we respectively named static osteogenesis (SO) and dynamic osteogenesis (DO), were observed in intramembranous ossification centers of newborn rabbits and chick embryos as well as during bone repair. In all cases the onset of intramembranous ossification is characterized by the appearance, around the vessels, of pluristratified cords of unexpect...

PURPOSE To trace the development of the normal fetal temporal bone by means of plain radiography, MR, and CT. METHODS Eighteen formalin-fixed fetal specimens, 13.5 to 24.4 weeks' gestational age, were examined with a mammographic plain film technique, CT, and MR imaging at 1.5 T. Temporal bone development and ossification were assessed. RESULTS The membranous labyrinth grows with amazing ra...

BACKGROUND Osteoconductive additives are used in resorbable interference screws for anterior cruciate ligament (ACL) reconstruction to improve graft incorporation and mitigate adverse effects. There are no published studies that compare biological performances of bioresorbable and biocomposite screws without artifacts due to different follow-up times and intrinsic patient characteristics. PUR...

Bone tissue is densely innervated, and there is increasing evidence for a neural control of bone metabolism. Semaphorin-3A is a very important regulator of neuronal targeting in the peripheral nervous system as well as in angiogenesis, and knockout of the Semaphorin-3A gene induces abnormal bone and cartilage development. We analyzed the spatial and temporal expression patterns of Semaphorin-3A...
