BACKGROUND Ovarian pregnancy is a rare and challenging clinical phenomenon. Recent studies have identified assisted reproductive treatments and infertility as risk factors. However, neither a definite mechanism nor clear risk factors were identified and therefore prevention strategies are yet unavailable. CLINICAL CASE In this article, we present a case of ovarian pregnancy occurring followin...

objective(s) the use of co-culture cells as well as extra cellular matrix are among those strategies that have been employed to direct mesenchymal stem cell (msc) bone differentiation in culture. in this regard, there is no study considering the effects of matrigel on mesenchymal stem cell (msc) in vitro bone differentiation. this was the subject of the present study. materials and methods huma...

objective: osteoporosis or silent disease is a major bone disorder in elderly women in current century. estrogen has an important role in osteogenesis and prevention of bone fractures. hormone replacement therapy (hrt) is usually accompanied by such effects as breast and ovary cancers. thus, there is an increasing demand for replacement with plant phytoestrogens. this study is focused on determ...

Wnt signaling pathways are essential for bone formation. Previous studies showed that Wnt signaling pathways were regulated by miR-375. Thus, we aim to explore whether miR-375 could affect osteogenesis. In the present study, we investigated the roles of miR-375 and its downstream targets. Firstly, we revealed that miR-375-3p negatively modulated osteogenesis by suppressing positive regulators o...

The basic assumption in the traditional inventory model is that all outputs are perfect items. However, this assumption is too simplistic in the most real-life situations due to a natural phenomenon in a production process. From this it is deduced that the system produces non-perfects items which can be classified into four groups of perfect, imperfect, reworkable defective and non-reworkable d...

Distraction osteogenesis is an important technique for the treatment of maxillofacial abnormities and defects. However, distraction osteogenesis may cause the injury of the inferior alveolar nerve. The relationship between distraction rate and nerve degeneration-regeneration shift remains poorly understood. In this study, 24 rabbits were randomly divided into four groups. To establish the rabbi...
