Mature teratoma is a benign germ cell tumor rarely located in the temporal bone. We are reporting a case of a mature teratoma of the temporal bone in a healthy borne 3.5-month-old baby girl with a 2-day suggestive history of otitis media and polypoidal mass expulsing from the external auditory canal of the left ear. A definitive diagnosis is made after complete excision and histological examina...
Donor organ transplantation is currently an essential therapeutic approach to the replacement of a dysfunctional organ as a result of disease, injury or aging in vivo. Recent progress in the area of regenerative therapy has the potential to lead to bioengineered mature organ replacement in the future. In this proof of concept study, we here report a further development in this regard in which a...
جایگزینی دندان های از دست رفته به وسیله ایمپلنت دندانی به فراوانی انجام میشود. برای اینکه ایمپلنت به طور بهینه جایگزین شود باید در استخوان ایده ال جایگذاری شود که البته این نقایص قابل ترمیم هستند، یکی از این روشها guided bone regeneration است.
The histologic evaluation of endochondral ossification is critical to the study of fracture healing, developmental biology, and comparative histology. A modification of Sayers’ alcian blue hematoxylin staining technique is described in which a different counterstain is applied. Paraffin sections are stained in alcian blue hematoxylin for 30 min, and then placed in orange G-eosin counterstain fo...
INTRODUCTION: The effects of gravity on bone metabolism are unclear. Most studies in humans and laboratory animal models have revealed that exposure to microgravity during spaceflight leads to bone loss, but the details of its mechanism are still unclear. On the other hand, some studies have reported the effects of hypergravity on mature skeleton, but the details of the effect of hypergravity o...
Bone is a unique organ able to regenerate itself after injuries. This regeneration requires the local interplay between different biological systems such as inflammation and matrix formation. Structural reconstitution is initiated by an inflammatory response orchestrated by the host immune system. However, the individual role of T cells and B cells in regeneration and their relationship to bone...
HYPOTHESIS The "in-bone" method of culturing utricles described here is a reliable and atraumatic technique for culturing mature mouse hair cells and studying hair cell death and protection. BACKGROUND The current in vitro technique for studying hair cells of the mature mouse utricle involves removal from the temporal bone and free floating culture in media. This technique can be problematic ...
