variation of the branches of the external carotid artery (eca) is well known, but it is extremely rare for the occipital artery (oa) to arise from the internal carotid artery (ica). a 87-year-old man was found to have this anatomical variation on the right side by threedimensional computed tomography angiography for vascular mapping of the carotid arteries before superselective intra-arterial c...

in order to study of nitrogen application time and seed inoculation with plant growth promotingrhizobacteria on yield, fertilizer use efficiency and grain filling rate of sunflower, a factorial experimentwas conducted based on randomized complete block design with three replications in research farm ofislamic azad university, ardabil branch in 2011. the first factor was time of nitrogen applica...

Introduction: Femur is the longest and strongest bone of human body. Its length associated with a striding gait, its strength weight muscular forces. It comprises an upper end, shaft lower end. Proximal part femur includes head, neck, greater lesser trochanters. Objectives: The present study aimed to record femoral head diameter parameters were carried out which would be help orthopedicians whi...

A key assumption of ethology is that characteristic behavior of organisms is that which brings some benefit, or in the jargon, “increased fitness,” to them or their kin. Innate (geneticallydetermined) behavior has this characteristic, e.g., the broken-wing feint of different species of ground-nesting birds which draws prey away from the nest of chicks. (This is not to deny that characteristic b...

allometric growth pattern and body shape changes of the green terror (andinoacara rivulatus)(cichlidae) were studied using landmark-based geometric morphometric (gm) and traditional methods, from hatching up to 1266 hours post hatching (hph) under culture conditions. the left side of specimens were photographed using digital camera and morphometric characters, including total length, head lengt...

PURPOSE To evaluate the performance of the Nidek MK-2000 and the LSK Carriazo Barraquer microkeratomes in the creation of corneal flaps for laser in situ keratomileusis (LASLK). METHODS A prospective randomized study of 55 eyes of 30 patients who underwent LASLK was performed. Twelve corneal flaps were created hy the Nidek MK-2000 microkeratome (160-/«n head), 30 corneal flaps by the Carriazo...

background: despite several reports regarding the use of the occlutech figulla® flex septal occluder (offso) in adults, there are few reports on its use in children. we sought to study the result of the transcatheter closure of atrial septal defect (asd) using the offso in children ≤ 12 years. methods: w e enrolled 45 consecutive patients, ranging from 2.5 to 12 years of age, in two large pedia...

abstract the saturated hydraulic conductivity (ks) is an important physical property of soil. the direct measurement of this property in soils is a difficult and time consuming process. pedotransfer functions (ptfs) provide an alternative by estimating soil parameters from more readily available soil data. the objective of this study is to determine effective factors on soil hydraulic conductiv...

PURPOSE We evaluate the clinical and radiographic midterm results of primary total hip arthroplasty (THA) using a 36 mm diameter femoral head on highly cross-linked polyethylene (minimum 7-year follow-up). MATERIALS AND METHODS We retrospectively reviewed 73 patients (74 hips) that underwent primary THA with a 36 mm diameter femoral head on highly cross-linked polyethylene between July 2004 a...

OBJECTIVE To establish reference intervals with gestation for the right and left lung areas and lung area to head circumference ratio (LHR). METHODS This was a cross-sectional study of 650 normal singleton pregnancies at 12-32 weeks of gestation. We measured the left and right lung areas on the cross-sectional plane of the thorax, used for examination of the four-chamber view of the heart, by...
