Intratester test-retest reliability of insertion gain measures.

Intratester test-retest reliability of insertion gain was determined on 28 subjects using the Frye 6500 real-ear analyzer. Results revealed mean differences of less than 1 dB for repeat measurements at six test frequencies between 250 and 4000 Hz. Also, over 80% of the repeat measures were within +/- 3 dB of the first measure. The results of this study are compared with previous studies of intratester reliability of insertion gain measures.

Use-effectiveness and analysis of satisfaction levels with the Billings Ovulation Method: two-year pilot study.

A 2-year study of 135 women using the Billings Ovulation Method as their method of family planning is reported. There were 1381 exposure cycles during the 1st year and 580 during the 2nd year. The total conception rates were 1.303 for the 1st year and 1.896 for the 2nd year. If one subtract the user failures from these rates, the biologic failure rates are 0.072 for the 1st year and 0.517 for the 2nd year. The continuation rate is 51.8%. An analysis of satisfaction levels is presented with a discussion of possible underlying emotional factors.

Efficacy of a recombinant fowl pox-based Newcastle disease virus vaccine candidate against velogenic and respiratory challenge.

A fowl pox-based recombinant virus TROVAC-NDV (vFP96.5) was developed expressing the fusion and hemagglutinin-neuraminidase glycoproteins from a velogenic strain of Newcastle disease virus (NDV). Studies in specific-pathogen-free birds indicated that inoculation of a single dose of the recombinant led to the induction of significant levels of hemagglutination-inhibiting antibody that were maintained to 8 wk postinoculation. Further, the recombinant induced protective immunity against a combined intramuscular velogenic NDV challenge and respiratory NDV challenge. In commercial broiler chickens that were inoculated in the presence of maternally derived NDV immunity, the level of the NDV-specific humoral response was dampened, but significant levels of protection against both a lethal intramuscular NDV challenge and a fowl poxvirus challenge were obtained.
