In the cranial vault, suture morphogenesis occurs when the growing cranial bones approximate and overlap or abut one another. Patency of developing sutures is regulated by the underlying dura mater. Once cranial sutures form, bone growth proceeds from the sutures in response to growth signals from the rapidly expanding neurocranium. Facial sutures do not develop in contact with the dura mater. ...

Lateral cord and median nerve are associated with variations. We observed concurrent variations in the formation of lateral cord and median nerve in thirty two formalin fixed cadavers. In 29.6% upper limbs Lateral cord was formed by anterior division of upper trunk only. In 21.8% of these cases the anterior division of middle trunk formed two additional roots for the median nerve and in 7.8% ca...

The models of the foot available in the literature are either two- or three-dimensional (3-D), representing a part of the foot without considering different segments of bones, cartilages, ligaments, and important muscles. Hence, there is a need to develop a 3-D model with sufficient details. In this paper, a 3-D, two-arch model of the foot is developed, taking foot geometry from the X-rays of n...

the distribution of yellowfin seabream populations in estuaries and inland rivers in coastal area of the persian gulf and strait of hormuz is presented. based on morphological and mersitic characteristics and also color pattern, these populations are assigned to the recently described sparid fish, acanthopagrus arabicus iwatsuki, 2013 which is distinguished by pelvic and anal fins vivid or stro...

Dallas, Texas Background: Projection of the nasal tip is a complex problem that often mandates attention during rhinoplasty. Occasionally, the goal is to decrease tip projection. Most published solutions to this problem involve division or manipulation of the lower lateral cartilages, although objective data on the efficacy of these techniques are limited. This study reviews a series of rhinopl...

Abstract We present the first known cranial remains of fossil batoid †Onchopristis numidus. Based on two exceptionally well-preserved specimens collected from ‘Kem Kem Beds’ (Albian–Cenomanian), south-east Morocco, an almost complete description rostral and portions genus is provided, together with new observations regarding development arrangement denticle series for this genus. The comparison...

Recent emerging data indicate that the increase in the expression and activity of the transforming growth factor beta 1 (Tgf-β1) signaling may have detrimental effect to mature articular cartilage of knee joints. However, there is no information about whether or not this is the case in condylar cartilages. The objective of this study is to investigate the protein expression and activity of Tgf-...

OBJECTIVE The purpose of this study was to determine whether or not patients with pectus excavatum (PE) exhibit costal cartilage overgrowth compared to normal subjects. MATERIALS AND METHODS The computed tomography acquisitions of 32 patients with PE and 35 normal controls were analyzed. On axial images the length of the 4th-7th costal cartilages was measured to calculate the Haller index. Th...
