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 ...

intracranial hemorrhage and entrapment neuropathy are the most serious and disabling complications in hemophilia.the occurance of these neurological complications was studied in 214 hemophiliac patients during a 3 month period. nine patients (4.2%) suffered intracranial hemorrhage (one epidural and others intracerebral). all of intracranial hemorrhage patients had the sevee form of disease (<1%...

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...

conclusions we determined the normative values of it thickness for the iranian fetuses in a pilot study, which may be considered for ntd screening during the first-trimester in the national and international guidelines. it is important to determine normal measurements of different ultrasonographic and biochemistry markers nationally, since there are significant differences among various ethnici...
