OBJECTIVE Many studies have shown that an increased nuchal translucency (NT) may be a good marker of fetal heart malformation, but the extent to which NT is suitable for identifying the population at risk remains unclear. We aimed to determine the value of NT measurement and of the presence of cystic hygroma colli in the screening of euploid fetuses for congenital heart defects (CHD). METHODS...
although measurement of intracranial pressure by noninvasive methods has been suggested, but mainly invasive methods are used for this purpose-increase in episcleral venous pressure can be expected to result in a linear increase in intraocular pressure. congested oculat veins with capillary leakage and hemorrhage are seen when the icp is increased, thus theoretically measurement of intraocular ...
When a surface is viewed through a partially-transmissive material, the optical contributions of the two layers in a given viewing direction are collapsed onto a single intensity in the projected image. If a computer vision system is to recover the scene correctly, it must be able to decompose or scission the image intensity into the separate contributions of the two material layers (see Fig. 1...
discussions as one ich patient whose pt and aptt suggest a coagulation disorder secondary to vitamin k deficiency or coagulation factor deficiency, unresponsiveness to vitamin k therapy should be useful to take fx deficiency into consideration. background inborn factor x deficiency (fxd) is a very rare (1: 500,000) hereditary coagulation disorder, which is characterized by clinical manifestatio...
The aim of this study is to evaluate the influence of modeling liquids on the translucency and color shade of resin composites (RCs) after one year of storage. RC specimens were prepared using either a conventional insertion technique (control; without modeling liquid) or a restorative dental modeling insertion technique (RDMIT) with dental adhesives as modeling liquids (Scotchbond™ Multi-Purpo...
STATEMENT OF PROBLEM For restorations with excellent esthetics, an understanding of the optical properties of human dentin is needed. Little information is available on the translucency and color parameters of dentin and its relationship to tooth type and position. PURPOSE The purpose of this in vitro study was to investigate the translucency and CIELab color coordinates of human dentin in bo...
background: to study the outcome of cases with nuchal translucency (nt) ≥ 95th centile in the first trimester of pregnancy. methods: this cross sectional study was performed at iranian fetal medicine foundation (fmf) between january 2009 and december 2011. totally, 186 cases with nt≥ 95th centile who attended for the first trimester screening were studied. all cases with increased nt including ...
