A prospective immunogenicity trial of measles and rubella vaccines was conducted in Oman. Children received measles vaccine at age 9 months and measles-rubella vaccine at age 15 months. Serum specimens were tested for measles-specific IgG and rubella-specific IgG. Of 1025 eligible infants, 881 (86.0%) returned for all five visits and had adequate serum samples for testing. Seroconversion to mea...

BACKGROUND Mortality of mothers and newborns is an important public health problem in low-income countries. In the rural setting, implementation of community based education and mobilization are strategies that have sought to reduce these mortalities. Frequently such approaches rely on volunteers within each community. OBJECTIVE To assess the perceptions of the community volunteers in rural K...

We studied the cross-resistance to three highly toxic Bacillus sphaericus strains, IAB-59 (serotype H6), IAB-881 (serotype H3), and IAB-872 (serotype H48), of four colonies of the Culex pipiens complex resistant to B. sphaericus 2362 and 1593, both of which are serotype H5a5b strains. Two field-selected highly resistant colonies originating from India (KOCHI, 17,000-fold resistance) and France ...

OBJECTIVE To investigate the association of NFKB1 -94 ins/del ATTG, NFKBIA -826C>T and NFKBIA -881A>G polymorphisms with risk of lung cancer in a Chinese population. METHODS Genotyping of the polymorphisms were performed on 1,436 subjects (718 cases and 718 controls) by using PCR-RFLP technique, followed by DNA sequencing. RESULTS We found a significant risk reduction associated with hetero...

Abstract We study recurrence in the real quadratic family and give a sufficient condition on rate $(\delta _n)$ of critical orbit such that, for almost every non-regular parameter , set n that $\vert F^n(0;a) \vert < \delta _n$ is infinite. In particular, when $\delta _n = n^{-1}$ this extends an earlier result by Avila Moreira [Statistical properties unimodal maps: family. Ann. Math. (2) 16...

The multiresolution wavelet expansion of digitized mammograms can be analyzed using a parametric statistical model for each image of the expansion. The statistical analysis of the individual expansion components is relatively simple, whereas the analysis of the original image is complicated. An important application of this technique is the statistical modeling of normal tissue in digital mammo...
