background: appropriate endurance exercise can change bone mass density and strength of weight-bearing bones in both animals and humans, but its effects on the microstructure are not known. this study aimed to determine skeletal changes induced by the treadmill running endurance in ovariectomized adult mice. methods: twenty-seven adult female rats were divided into experimental and control grou...
Ewing's sarcoma is a relatively common malignant bone tumor that typically occurs in long bone diaphyses of adolescents and young adults of 10-30 years old. Often times, all Ewing's sarcoma of bone have radiographic abnormalities. Diagnosis is usually delayed and can be misdiagnosed as osteomyelitis. Bone to bone metastasis occurs, but soft tissue retro bulbar metastas...
Piezoelectric materials are the group of smart materials which have been recently developed for biomedical applications, such as bone tissue engineering. These materials could provide electrical signals with no external source power making them effective for bone remodeling. Between various types of materials, BaTiO3 and CaTiO3 are nontoxic piezoelectric ceramics, which recently have been intro...
In the present work, dose equivalents of radiosensitive organs in head and neck region have been calculated during nasopharynx proton therapy. For this purpose, a middle-size tumor was designed with the use of clinical information, and was then incorporated into the adult male ICRP phantom. According to the medical data, eight radiation paths around the neck were selected. After that, appropria...
The os cordis (heart bone) is a rare bone found only in few animals the world. We discovered an some chimpanzees. was males and females, young old animals. It not present chimps with healthy hearts, those severe heart disease. also that tissue called cartilage around bone. presence of gives us clues about how why these bones develop.
