background: considering that establishment of reference value of nuchal translucency (nt)-related to the crown rump length (crl) during the first trimester will be helpful for determining an appropriate cutoff level for  screening of increased nt thickness-related abnormalities, we determined the nt thickness and investigated its relation with diff erent chromosomal and nonchromosomal abnormali...

Objective: Determine the translucency and radiopacity of five commercially availablecomposites: Aelite LS(AE), Filtek LS(FS), GC Kalore(KA), Empress DirectEnamel(EE), Empress Direct Dentin(ED)Experimental Methods: Experiment conducted according to ISO guideline 4049.Five composites(n=50), shade A2, were packed into an aluminum mold(10-mm diameter,1-mm thick) and light cu...

The set of dental traits traditionally used for identification purposes due to their high correlation with age include the attrition crown, periodontic changes, apposition secondary dentin and root cement, resorption translucency root. work puts forward a proposal add new trait, i.e. width canal. trait is particularly useful examination fossil material.

Noonan syndrome is a genetically heterogeneous condition primarily due to missense mutations in PTPN11. Prenatal diagnosis is typically made in a fetus with increased nuchal translucency and normal karyotype. We demonstrate the ability of whole exome sequencing to make prenatal diagnoses that would not have been made from phenotype alone.

We also demonstrate the effectiveness of SART in generating dynamic real-time scenes (20 fps on an Nvidia Pascal GPU). Unlike traditional 2D displays, light field displays provide binocular depth cues such as high-resolution motion parallax, occlusion, translucency, and specularity. In particular attenuation-based light field displays provide an inexpensive means by which to produce these unenc...

OBJECTIVE This in vitro study evaluated the effect of two different shades of resin cement (RC- A1 and A3) layer on color change, translucency parameter (TP), and chroma of low (LT) and high (HT) translucent reinforced lithium disilicate ceramic laminates. MATERIAL AND METHODS One dual-cured RC (Variolink II, A1- and A3-shade, Ivoclar Vivadent) was applied to 1-mm thick ceramic discs to creat...

It is now clear that the vast majority of major fetal abnormalities can be diagnosed prenatally by ultrasound, that most of these abnormalities can be detected in the first trimester of pregnancy and that women want firsttrimester rather than later diagnosis. It is also clear that effective diagnosis of fetal abnormalities often necessitates the identification of easily recognizable markers whi...
