OBJECTIVES This study investigates how lifecourse, immigrant status and acculturation, and neighbourhood of residence influence food purchasing and preparation among low-income women with children, living in the USA. This research sought to understand physical and economic access to food, from both 'individual' and 'community' perspectives. DESIGN This study used qualitative methodology (focu...

Listeria monocytogenes (Lm) is a food-borne pathogen responsible for human listeriosis, an invasive infection with high mortality rates. Lm has developed efficient strategies for survival under stress conditions such as starvation and wide variations in temperature, pH, and osmolarity. Therefore, Lm can survive in food under multiple stress conditions. Detailed studies to determine the mode of ...

Fresh fruits, nuts and vegetables are increasingly linked to food-borne illnesses, outbreaks and recalls. The trend represents a modern-day public health conundrum wherein consumers are encouraged to eat more fresh produce to help prevent chronic health problems such as obesity and heart disease, but at the same time consumption of contaminated produce can lead to potentially life-threatening a...

Our objective was to examine the association between ethnicity and birthplace and the percent of energy from selected food groups among Hispanics, the largest growing segment of the US population. We used data from NHANES 1999-2004, collected from Mexican (n = 3375) and other Hispanic (n = 622) adults (18 y and older), classified as foreign born (FB) or US born (USB). Using University of North ...

OBJECTIVE This study was designed to determine whether a community sample of obese mothers with young children used different feeding styles compared with a matched sample of normal-weight mothers. Four aspects of feeding style were assessed: emotional feeding, instrumental feeding (using food as a reward), prompting/encouragement to eat, and control over eating. RESEARCH METHODS AND PROCEDUR...

1101 Anything that’s alive runs the risk of infection. How you respond to infection, however, depends on where you sit on the evolutionary tree. Humans and other vertebrates can fend off billions of pathogens by routinely recombining bits of genes for surface molecules on the cells charged with pathogen recognition. Insects and other invertebrates rely to a large degree on the pathogen recognit...

We report the use of genetically engineered cells in a pathogen identification sensor. This sensor uses B lymphocytes that have been engineered to emit light within seconds of exposure to specific bacteria and viruses. We demonstrated rapid screening of relevant samples and identification of a variety of pathogens at very low levels. Because of its speed, sensitivity, and specificity, this path...

Craving is considered a key characteristic of diverse pathologies, but evidence suggests it may be a culture-bound construct. Almost 50% of American women crave chocolate specifically around the onset of menstruation. Research does not support popular accounts implicating physiological factors in menstrual chocolate craving etiology. We tested the novel hypothesis that greater menstrual craving...
