Physical Fitness and Embedded Figures Test Performance of Elementary School Children

The relationship between physical fitness and field independence was assessed by measuring embedded-figures test performance in the following four groups of children in Grades 4 through 6: (1) 93 boys high in physical fitness, (2) 92 girls high in physical fitness, (3) 67 boys low in physical fitness, and (4) 77 girls low in physical fitness. The group of girls low in physical fitness was significantly more field dependent than the other three groups. No significant differences were found among the other three groups. It appears that skill in physical activities may be related to the embedded-figures test performance of girls, but not boys. In fact, girls skilled in physical activities may be as field independent as boys.

Phenobarbital monitoring in whole blood with a quantitative noninstrumented test

The AccuLevel phenobarbital test is based on enzyme channeling and immunochromatography. AccuLevel is a noninstrumented test for the quantitative determination of phenobarbital concentration in whole blood. Within-run precision data, with 20 replicates at each of five concentrations, has coefficients of variation (CVs) of 4.7-9.2%. Between-run precision (n = 40) results in a CV of 5.9%. The AccuLevel phenobarbital test is very specific and is unaffected by endogenous substances and blood collection tube anticoagulants. Compared to the Emit method, this test has excellent linear correlation for the quantitation of 104 phenobarbital positive patient samples. Reagents stored at 4-8 degrees C are stable for 15 months with no effect on the assay quantitation. This accurate, precise, and specific test is easily performed in 20 min.

Mate Selection and Behavioral Thermoregulation in Fowler's Toads

Male Fowler's toads produce mating calls that are affected by the body size and temperature of the caller. Females are able to discriminate between variations in these calls and select the largest available males. By thermoregulation, males are able to alter their calls to make them more attractive to females.
