A master element to be employed as a general spatial rod finite element is presented. This spatially curved and pretwisted element can have variable cross-section and variable curvature change. It may also be resting on an elastic foundation. Also, a finite element formulation for a general earthquake analysis of spatial rods is presented. The theoretical foundation has lead to a general-purpos...

fryns-aftimos syndrome is a rare autosomal dominant disorder characterized by craniofacial signs, anterior neuronal migration disorder (pachygyria, lissencephaly), skeletal deformities and mental retardation. we describe a five-year-old boy with abnormal facial features (hypertelorism, ptosis, high arched palate), skeletal problems (short stature, short fingers, flat feet) and mild intellectual...

Background: The existence of fluoride ion in potable water has distinctive effects on human health. Fluoride is attracted by positively charged calcium in teeth and bones due to its strong electro-negativity which results in dental, skeletal, and non-skeletal forms of xuorosis and associated health complaints in children as well as adults. Methods: Water samples from groundwater used for dri...

I-cell disease is a rare inherited metabolic disorder resulting from a defective phosphotransferase, characterized by coarse facial features, skeletal abnormalities and mental retardation. As clinical features of this condition mimic that of Hurler disease mutation studies help in the diagnosis. We present a case of I-cell disease in a neonate with GNPTAB gene mutation.

The ossification centers onset of the quail vertebrae, ribs, and sternum in embryos and hatchling birds was studied. Specimens were cleared, stained with Alcian Blue and Alizarin Red S and examined using stereomicroscope. The chondral rudiments of the vertebrae were observed at the 6th day of incubation (E6). The osteogenesis of the vertebrae was accomplished with both perichondral a...

background: in diabetes mellitus because of the absence or insufficient sensitivity to insulin, glucose transporter protein in cell membrane, glucose transporter 4, is decreased. glut4 is the major glucose transporter in skeletal muscle and adipose tissue, which is under control of insulin. it remains, however, unclear whether cinnamaldehyde plays a regulatory role(s) or not. objectives: the ob...

holt-oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. they range from clinodactyly, absent or digitalised thumb, hypoplastic...

background: the aim of this study was to compare the skeletal and dental changes of a toothborne (hyrax) and a bone-borne (smile distractor) expansion devices using three-dimensional model of a human skull. materials and methods: a finite element model of human skull was generated using data from 3-d ct scans of an 11-year-old female child. then a hyrax expander (tooth-borne appliance) and smil...

original article   occupational diseases are any chronic ailment that occurs as a result of work or occupational activity. this study was conducted to examine the frequency and risk factors of some skin and musculoskeletal disorders among nurses at a referral-teaching hospital. all 197 nurses in the hospital from different working shifts were engaged in the study. all nurses filled out a questi...
