PURPOSE The purpose of this study is to mix dental ceramic powder in varying ratios and evaluate the effect of the mixing ratio on color and translucency. MATERIALS AND METHODS The ceramic powder of shade A3 of the same product was mixed with the shade A2 of three products: IPS e.max Ceram (Ivoclar Vivadent, Schaan, Liechtenstein), Vintage Halo (SHOFU Inc., Kyoto, Japan), and Ceramco 3 (Ceram...

INTRODUCTION Numerous papers have proven that an increased nuchal translucency is connected with a raised risk of chromosomal aberrations, but few analyses are related to the further state of fetuses with a normal karyotype. THE AIM OF THE STUDY The aim of the study was to estimate the risk of cardiac defects and other developmental disorders in fetuses with increased nuchal translucency and ...

In a study of 50 cases of trisomy 18 compared with 947 controls we have found the median multiple of the median (MoM) of maternal serum free human chorionic gonadotrophin to be significantly decreased (0.281 MoM) in samples collected between the 10th and 14th week of gestation. Similarly, maternal serum pregnancy associated plasma protein A (PAPP-A) levels are also decreased (0.177 MoM), whilst...

OBJECTIVE To compare the effects, safety, and cost effectiveness of antenatal screening strategies for Down's syndrome. DESIGN Analysis of incremental cost effectiveness. SETTING United Kingdom. MAIN OUTCOME MEASURES Number of liveborn babies with Down's syndrome, miscarriages due to chorionic villus sampling or amniocentesis, health care costs of screening programme, and additional costs...

The greenhouse whitefly Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) is a pest of a wide range of vegetable and ornamental crops in greenhouses around the world. Yellow sticky traps are highly attractive to flying adults and so are frequently used to monitor the pest. Our aim was to test whether changes in trap translucency or the addition of printed black patterns could increa...

The aim of this study is to evaluate the color stability, translucency and hardness eight different composite resins, after thermal cycling immersion in beverages. Six light-cured dimethacrylate-based (Clearfil Majesty Esthetic, Clearfil Posterior, Grandio, Grandio Flow, Arabesk Top, Valux Plus), an ormocer (Admira) a silorane-based (Filtek Silorane) were tested study. Fifteen samples (8x2 mm) ...

Background Nuchal translucency (NT) is the sonographic appearance of a collection of fluid under the skin behind the fetal neck in the first-trimester of pregnancy. In fetuses with chromosomal abnormalities, cardiac defects and many genetic syndromes NT thickness is increased. The aim of the study was to evaluate the incidence of major cardiac defects in relation to the fetal NT in chromosomall...

OBJECTIVE Quantitative analysis of the quality of nuchal translucency (NT) measurements. METHODS First-trimester combined screening for Down syndrome was performed to all pregnant women attended in our Department from October 2003 to November 2009. NT was measured according to the Fetal Medicine Foundation (FMF) criteria by 20 trained obstetricians. The performance of NT measurements was retr...

In the cosmetics industry, fine particles suspended or dispersed in a medium are widely used. Optical properties of can be an indicator for evaluating performance cosmetic product, such as ultraviolet protection capacity sunscreens and also its appearance. However, relationship between optical appearance product has not been clarified. this study, dispersions with titanium dioxide zinc oxide we...
