Abstract: Dimetrodon sp. femur, jaw, teeth, and rib bones were collected at N.E. Frederick, OK, sectioned for histological examination. This Oklahoma Museum of Natural History site has yielded well-preserved Paleozoic fossils decades. All heavily infiltrated with calcite other minerals, yet a reddish-brown mass obstructed many vascular channels. reacted to 374 nm UV illumination by emitting bri...

In the last decades, researchers have developed new materials to improve the quality of human life. Owing to the frequent occurrence of bone fractures, it is important to develop plate materials for the fixation of fractured bones. These plate materials have to be lightweight, compatible with human tissues and ought to allow stiffness. Natural fibers have the advantage that they are renewable r...

Bones are vital and strong, but not invincible—they can be broken. Normally, bones repair themselves. However, sometimes broken must supported using what is called an implant. An implant a man-made device used to replace or support missing part of the human body. In case bone, aims at helping bone regain its natural function. inserting foreign object into body has several possible complications...

We describe two carnivoran coprolites found in the pseudokarst natural carnivore trap of Batallones-3, from Late Miocene Spain. The larger one, comprising multiple indistinguishable fragments broken and corroded bones, indicates that producer dropping might have been highly capable crushing softer parts large bones. On other hand, smaller one shows several relatively more complete bone fragment...

Bones, even after their growth has been completed, react to both external and internal factors which include feeding. The process of bone mineralization, including limb bones, is a very important index of the effectiveness and quality of feeding procedures, aswell as a measure of the organism’s health status. Antibiotics, which used to be very popular growth stimulators in feeding, have recentl...

The mechanisms by which bone resorbing osteoclasts form and are activated by hormones are poorly understood. We show here that the generation of oxygen-derived free radicals in cultured bone is associated with the formation of new osteoclasts and enhanced bone resorption, identical to the effects seen when bones are treated with hormones such as parathyroid hormone (PTH) and interleukin 1 (IL-1...
