PURPOSE The aim of this study was to compare the trueness and precision of four intraoral scanners used in oral implantology. METHODS Two stone models were prepared, representing a partially and a totally edentulous maxilla, with three and six implant analogues, respectively, and polyether-ether-ketone (PEEK) cylinders screwed on. The models were digitized with an industrial scanner (IScan D1...

Ascent to extreme High Altitude (HA) is in steps and it entails acclimatization at moderately HA locations. In terms of acclimatization, it is pertinent to understand the physiological changes, which occur on immediate ascent to moderate HA. The study aimed to evaluate the effect of ascent to 3500 m on neuro-endocrine responses in the first hour of induction. The plasma levels of catecholamines...

INTRODUCTION We previously presented an investigation on the Specific Absorption Rate (SAR) and temperature elevation using Japanese anatomical human models for body-worn usage at 900, 1950, and 3500 MHz [1]. The results showed that there was a difference in the 10g average SAR between the male and the female models, but the temperature elevation was almost the same at 900 and 1950 MHz and vice...

To achieve selective inhibition of cytosolic and membrane-bound carbonic anhydrase (CA II and CA IV, respectively), we synthesized a polymer of molecular weight 3500 from polyoxyethylene bis acetic acid and aminobenzolamide. The new compound, designated F (for Florida) 3500, is stable, water soluble and nontoxic. It is excreted largely unchanged by glomerular filtration. The Ki at 37 degrees C ...

Context. The chemistry in the inner few thousand AU of accreting envelopes around young stellar objects is predicted to vary greatly with far-UV and X-ray irradiation by the central star. Aims. We search for molecular tracers of high-energy irradiation by the protostar in the hot inner envelope. Methods. The Submillimeter Array (SMA) has observed the high-mass star forming region AFGL 2591 in l...

Among the many different types of table olives, production dehydrated black olives is rather low worldwide, although there an increasing interest in them from consumers. The physicochemical and microbiological characterization 20 samples these obtained countries processing methods was studied. average pH water activity (a w ) values were 4.7 units 0.85 respectively, a great variability found am...

Background: Knowledge of the weight of the foetus in utero is important for the obstetricians to decide the time and mode of delivery. It can be estimated clinically, biochemically or by radiological imaging .None of the diagnostic tools are direct .Interestingly clinically estimated foetal weight is being found more precise than radiological estimation Aim:. This study was designed to find the...

BACKGROUND Although linear growth during childhood may be affected by early-life exposures, few studies have examined whether the effects of these exposures linger on during school age, particularly in low- and middle-income countries. METHODS We conducted a population-based longitudinal study of 256 children living in the Brazilian Amazon, aged 0.1 y to 5.5 y in 2003. Data regarding socioeco...
