Translucency of human dental enamel was determined by total transmittance of wavelengths from 400 to 700 nm. The transmission coefficient at 525 nm was 0.481 mm-1. Total transmission of light through human dental enamel increased with increasing wavelength. Human tooth enamel is more translucent at higher wavelengths. The translucency of wet human enamel and enamel after dehydration was also me...

The aim of this in vivo study is to describe the clinical threshold and relative factors associated with translucency maxillary central incisors. Bilateral incisors were measured 106 individuals using a digital colorimeter against black white backings. parameters (TP) difference TP (?TP) between left right same individual was calculated. mean value 8.22. There significant effect age on (p<0.05)...

OBJECTIVE To investigate the prevalence of detectable jugular lymphatic sacs in a setting for first trimester screening for Down syndrome, and to evaluate the influence of jugular lymphatic sacs on the screening performance for chromosomal abnormalities. METHODS A prospective single center study (Erasmus University Medical Center, Rotterdam, The Netherlands) over a period of one year (January...

OBJECTIVE To investigate the feasibility and repeatability of nuchal translucency thickness measurement using three-dimensional ultrasound. METHODS Forty consecutive women with uncomplicated singleton pregnancies attending for Down syndrome screening at 11-14 weeks' gestation were included in this prospective crossover trial. Nuchal translucency thickness was measured using both two-dimension...

The removal of pineapple crowns and slips during the final stage fruit development can alter source-sink relationships quality. Published results have reported both positive negative effects crown slip on size In this study, four treatments: control (no treatment), removed by hand, with a knife, were evaluated to clarify effect Crowns one two months before expected harvest date, soon after bega...

Objective: Translucency is the most nebulous attribute that describes ideal skin appearance. Physics would define an object as translucent if light can partially pass through it. However, skin translucency is not only about light passing through the skin. P&G research shows that the perception of skin translucency is a holistic term that involves the integration of skin color, glow and texture....

Note: It should be noted that appropriate training of ultrasonographers with ongoing quality assurance programs are considered critical to the accurate measurement of fetal nuchal translucency. In addition, in published studies of first trimester screening, the laboratory and imaging components of screening (i.e., fetal nuchal translucency and measurement of maternal serum factors) are performe...

An approach to the recognition of lesions on chest radiographs is outlined. Four basic groups of abnormalities by means of which lesions can be recognized are mentioned and are briefly described, namely an opacity, an area of increased translucency, a combination of an opacity and an area of increased translucency, and, especially, an alteration in normal radiological anatomy.

BACKGROUND Previous studies showed that soluble LHCGR/hCG-sLHCGR concentrations in serum or plasma combined with PAPP-A and free βhCG significantly increased the sensitivity of Down's syndrome screen at early pregnancy without altering the false positive rate. The goal of the present study was to further examine the role of sLHCGR forms as combinatorial markers and to investigate whether sLHCGR...
