The objectives of this study were to estimate the maxillary arch measurements, to assess the validity of Pont's & Korkhaus' Indices; to determine the relationship between maxillary arch form with head form; and to estimate the cephalic index (CI) of the study population. A cross-sectional study was conducted on 85 mature Malay students, 28 male students (32.98%), 57 females (67.02%) attending T...

The embryonic arches develop in the fourth and fifth gestational weeks with the corresponding pharyngeal arch arteries connecting the aortic sac with the dorsal aorta. The fourth arch forms the aorta; the left sixth arch forms the left pulmonary artery and duct. The fifth aortic arch is a transient developmental structure in humans as there is no 5th pharyngeal arch; indeed, its existence has, ...

OBJECTIVE Implants are being used in orthodontics as a reliable mode of anchorage. Among other factors, the cortical bone thickness plays a major role in determining the stability of these implants. The objective of this study was to study the relationship of various arch forms and the cortical bone thickness and to determine if the cortical bone thickness varies between various arch forms. Thi...

Overexpression of Hoxa2 in the chick first branchial arch leads to a transformation of first arch cartilages, such as Meckel's and the quadrate, into second arch elements, such as the tongue skeleton. These duplicated elements are fused to the original in a similar manner to that seen in the Hoxa2 knockout, where the reverse transformation of second to first arch morphology is observed. This co...

AIMS To investigate the role of the geometry of the aortic arch in resting hypertension after successful repair of coarctation (CoA). METHODS AND RESULTS 105 patients (15.3+/-6 years) with successful repair of aortic CoA underwent blood pressure (BP) measurements at rest and magnetic resonance imaging (MRI) of the aortic arch and left ventricle. Three categories of aortic arch shape were defi...

PURPOSE To evaluate the effect of reduced z-axis scan coverage on diagnostic performance and radiation dose of neck CT in patients with suspected cervical abscess. METHODS Fifty-one patients with suspected cervical abscess were included and underwent contrast-enhanced neck CT on a 2nd or 3rd generation dual-source CT system. Image acquisition ranged from the aortic arch to the upper roof of t...

in this paper, we study spacelike dual biharmonic curves. we characterize spacelike dual biharmonic curves in terms of their curvature and torsion in the lorentzian dual heisenberg group . we give necessary and sufficient conditions for spacelike dual biharmonic curves in the lorentzian dual heisenberg group . therefore, we prove that all spacelike dual biharmonic curves are spacelike dual heli...
