چکیده

The objective of this study was to determine the mechanical properties on different size of cranial sutures in rat and same-aged mice. Ten sagittal sutures were harvested from 4-month-old Lewis rats and C57BL/6 mice. The specimens, kept moist, were mounted fresh and distracted until rupture. Load-displacement curve was constructed. The stiffness, Young’s modulus, fracture stress and fracture energy were calculated. Moreover, fracture mechanism, SEM images, AFM images are also discussed. The discuss of different cranial size on mechanical properties of cranial suture in rat and same-aged mices was also provided. The results show difference between the two groups with higher values from rat. It shows the higher mechanicl properties occurred mainly on the large type of build in our mammal system.

Determination of Cranial Index in Sagittal Synostosis using Artificial Intelligent Techniques

Background: At least one main suture of skull is closed prematurely in craniosynostosis; which may lead to different skull and face deformities and various types of child developmental delay. Increased postero-anterior diameter of skull is the main characteristic of sagittal craniosynostosis. Cranial index is the most important parameter for diagnosis and monitoring of children with this deform...

EFFECT OF PASSIVE SMOKING DURING PREGNANCY ON WEIGHT, LENG TH AND CRANIAL CIRCUMFERENCE AT BIRTH IN KERMAN, IRAN

Passive smoking (PS), a well-known health risk, is the major source of indoor pollution. There is some inconsistent evidence that PS during pregnancy may increase the risk of low birth weight. The aim of the present study was to determine the effects of PS exposure during pregnancy on weight, length and cranial circumference at birth of babies born to women who have described themselves ...
