An open, self-controlled study on the efficacy of topical indoxacarb for eliminating fleas and clinical signs of flea-allergy dermatitis in client-owned dogs in Queensland, Australia.

Background: Canine flea-allergy dermatitis (FAD), a hypersensitivity response to antigenic material in the saliva of feeding fleas, occurs worldwide and remains a common presentation in companion animal veterinary practice despite widespread availability of effective systemic and topical flea-control products.

Hypothesis/objectives: To evaluate the clinical response in dogs with FAD treated topically with indoxacarb, a novel oxadiazine insecticide.

Animals: Twenty-five client-owned dogs in Queensland, Australia diagnosed with pre-existing FAD on the basis of clinical signs, flea-antigen intradermal and serological tests.

2-Phenylimidazo[1,2-b]pyridazine derivatives highly active against Haemonchus contortus.

A series of 2-phenylimidazo[1,2-b]pyridazine derivatives were synthesized and evaluated for their in vitro anthelmintic activity against Haemonchus contortus. The most active compounds had in vitro LD(99) values of 30nM, which is comparable to that of the benchmark commercial nematocide, Ivermectin.

My contribution to broadening the base of chemical engineering.

This paper is a short account, from a personal viewpoint, of the various contributions I have made to expand the academic basis of chemical engineering from its origin in the unifying concept of unit operations, focussed on process design, to encompassing all the professional activities of industrial chemical engineers. This includes all aspects of planning and scheduling the operations as well as designing and controlling the process plant. The span of my career also happens to include the birth of the age of computing, with all the consequential implications.

Discovery of ectoparasiticidal hydrazonotrifluoromethanesulfonanilides.

A series of hydrazonotrifluorosulfonanilide derivatives were synthesized and evaluated for in vitro activity against the ectoparasites Ctenocephalides felis and Rhipicephalus sanguineus. Some compounds with excellent activity against tick were identified.

Selected health behaviors that influence college freshman weight change.

Objective And Participants: The authors investigated the effect of physical activity (PA), fruit and vegetable intake, and alcohol use on 6-month weight change in 193 college freshmen (78.8% white, 88.2% women, 94.

Parasiticidal 2-alkoxy- and 2-aryloxyiminoalkyl trifluoromethanesulfonanilides.

A series of novel 2-alkoxy- and 2-aryloxyiminoalkyl trifluoromethanesulfonanilide derivatives have shown significant in vitro parasiticidal activity against the ectoparasites Ctenocephalides felis and Rhipicephalus sanguineus. A number of these compounds also displayed significant in vitro endoparasite activity against the nematode Haemonchus contortus.

Discovery of (Z)-2-phenyl-3-(1H-pyrrol-2-yl)acrylonitrile derivatives active against Haemonchus contortus and Ctenocephalides felis (cat flea).

A series of 2-phenyl-3-(1H-pyrrol-2-yl)acrylonitrile derivatives were synthesized and evaluated for in vitro activity against the endoparasite Haemonchus contortus and the ectoparasite Ctenocephalides felis. Some compounds had significant in vitro activity against these parasites.

Factors of fruit and vegetable intake by race, gender, and age among young adolescents.

Objective: To explore demographic differences in individual, social, and environmental factors potentially related to fruit and vegetable intake.

Design: Self-report questionnaires administered to a convenience sample of middle school students during regular classes.

Participants: Black and white adolescents, 11 to 15 years of age (N = 736).

The changing age of HIV: sexual risk among older African American women living in rural communities.

Background: African American women aged 50 and older are disproportionately affected by the HIV/AIDS epidemic. Despite African Americans making up 11% of all older women in the United States, in 2001, they accounted for more than 50% of AIDS cases among older women and more than 65% of HIV cases among older women. Using the AIDS Risk Reduction Model as a conceptual framework, this study investigated HIV risk behavior among older rural African American women (mean age = 58 years).

A replicable process for redesigning ethnically relevant educational materials.

Background: To serve the populations targeted by Well-Integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN) effectively, healthcare providers need educational materials that are evidence based and ethnically relevant and can be easily incorporated into busy clinic settings. We describe a replicable process used to redesign and tailor physical activity and diet education materials for African American women in the southeastern United States.

Methods: The process consists of seven phases.

Examining gender, racial, and age differences in weight concern among third, fifth, eighth, and eleventh graders.

Weight management and concern, body weight beliefs, and perceptions of friend's and family's weight concerns were examined in this study by race, grade, and gender. A stratified random sample was used to select schools within nine districts in South Carolina and an anonymous self-report paper-pencil questionnaire was completed by the students. The final sample included 3151 African American (42.

Covariations of adolescent weight-control, health-risk and health-promoting behaviors.

Objectives: To assess the prevalence of dieting and investigate clusters of risk behaviors among adolescents.

Methods: Data were secured from a random sample of adolescents (4,636) and analyzed using bivariate methods and logistic regression.

Results: From the survey sample, 19.

Dietary practices of South Carolina adolescents and their parents.

Objective: To assess and identify correlates of adolescents' and parents' compliance with food guide pyramid recommendations (FGPR) and weight-control behaviors (WCB).

Methods: Data were collected from a random sample of adolescents (2,021) and parents (1,231) and were analyzed using multiple and logistic regression.

Results: Only 7% eight graders, 4% eleventh graders, and 3% parents met all FGPR.

Differences in diet quality among fourth and seventh grade public school students in South Carolina.

The purpose of this study was to compare various aspects of diet quality between fourth graders and seventh graders. Consumption in each food group and food variety pattern suggested that dietary quality of fourth graders and seventh graders were different. Fourth graders showed "better" dietary behaviors than seventh graders with some variations among food groups and differences regarding gender.
