background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...

Whether children who receive CIs gain normal speech production abilities is unknown. OBJECTIVE To assess speech and articulation in deaf, long-term CI users who had undergone early unilateral cochlear impl...

in order to assess the risk for mercury poisoning in dentists, urine specimens were collected and analysed from 250 dentists (190 male, 60 female). subject data and pertinent health symptoms were asked via a questionnaire. the results indicate that the mean and standard deviation of mercury values were 51.3± 38.0 µg/l, while 27.2 percent of dentists had levels within normal limits (0-19 µg/l). ...

We estimated the number of colors perceived by color normal and color-deficient observers when looking at the theoretic limits of object-color stimuli. These limits, the optimal color stimuli, were computed for a color normal observer and CIE standard illuminant D65, and the resultant colors were expressed in the CIELAB and DIN99d color spaces. The corresponding color volumes for abnormal color...
