Background: For design of suitable spinal implants, computational investigation of stresses developed within spine as a result of implantation is very important. Hence, the present study has been carried out for computation of stresses developed within Cervical Spine area during various neck motions using Finite Element method, for natural spine as well as for spines with implantation of both t...

background: the aim of the present study was to evaluate the relationship between the bone density of various regions of jaws and skeletal bones. materials and methods: a total of 110 patients with a mean age of 55.01 ± 10.77 years were selected for the purpose of the present descriptive study. dual x-ray energy absorptiometry (dxa) was carried out to determine bone mineral density (bmd) of the...

Regeneration of fractured or diseased bones is the challenge faced by current technologies in tissue engineering. The major solid components of human bone consist of collagen and hydroxyapatite. Collagen (Col) and hydroxyapatite (HA) have potential in mimicking natural extracellular matrix and replacing diseased skeletal bones. More attention has been focused on HA because of its crystallograph...

BACKGROUND AND OBJECTIVES Deproteinization is an indispensable process for the elimination of antigenicity in xenograft bones. However, the hydrogen peroxide (H2O2) deproteinized xenograft, which is commonly used to repair bone defect, exhibits limited osteoinduction activity. The present study was designed to develop a new method for deproteinization and compare the osteogenic capacities of ne...

An adult human skull was discovered in a college osteological collection presenting with two Inca bones. Inca bones or interparietal (supernumerary) bones are rarely seen among dry human skulls. Their frequency of presentation is much less than that of sutural or Wormian bones. Inca bones or interparietal (supernumerary) bones are accepted as normal variants most often found in the occipitopari...

Frederic Webster, chief preparator at the Carnegie Museum (CM) from 1897 to 1907, is credited by some for “rescuing” Lion Attacking a Dromedary (LAD) destruction American of Natural History. Webster's work on LAD was not his only involvement with preparation and display controversial bones, however. Webster mounted hide bones Confederate General Thomas “Stonewall” Jackson's war horse, Little So...

New data on the species composition of late Middle Ages paleofauna (13-15 centuries) are published, obtained from excavation materials hillforts Aspara and Sharuashylyk in valleys Shu Talas rivers. The hillfort is located foothill plain north Kyrgyz Alatau, left bank river. tributary lower reaches Talas, semi-desert zone, at southwestern outskirts sandy desert Moyynkum. A comparative study medi...

Bones have a complex hierarchical structure that supports their diverse chemical, biological, and mechanical functions. High rates of bone susceptibility to fractures injury attracted extensive research interest find alternate biomaterials for scaffolds. Natural healing is only successful if the defect very small when exceeds 1 cm3 then grafting required. Large defects or injuries are serious p...

Background: Osteoporosis is a condition in which the bones become brittle, increasing the risk of fractures. Complementary medicines have traditionally used animal bones for managing bone disorders, such as osteoporosis. This study aimed to discover new natural products for these types of conditions by determining mineral and protein content of bone extracts derived from the Australian wallaby....
