A small study was carried out in order to examine the molecular presence of bla CTX-M gene phylogenetic groups in E. coli (n=263) isolated from food (n=54), water (n=7), animal sources (n=69), using consensus bla CTX-M primers and PCR, in addition to human faecal isolates (n=69) and VTEC O157:H7 (n=64). None of the clinically significant faecal VTEC O157:H7 isolates were shown to carry blaCTX-M...
In the early 1970s, the largest industrial accident in the United States resulted in widespread contamination of the food supply in Michigan with polybrominated biphenyls (PBBs). The chemical similarity of PBBs to compounds implicated as endocrine disruptors has raised the question of whether PBBs could affect the reproductive system. In the present analysis we examine the relation between seru...
World population has already exceeded 6.5 billion, out of which about 850 million (13 percent) are undernourished. With the current growth rate, the world community faces even a greater challenge of hunger and food security as the estimated the population will catch 9 billion by the year 2050 with doubled needs for food. At the same time, preservation of biodiversity, stopping deforestation and...
Most research on cognitive processes in craving has been carried out in the laboratory and focuses on food craving. This study extends laboratory findings to real world settings and cravings for drugs or activities as well as food. Previous laboratory research has found that playing Tetris reduces craving strength. The present study used an ecological momentary assessment protocol in which 31 u...
BACKGROUND The Internet contains a plethora of nutrition information. Health organizations are increasingly using the Internet to deliver population-wide health information and interventions. Effective interventions identify their target population and their needs; however, little is known about use of the Internet as a source of nutrition information. OBJECTIVE The aim was to assess the chan...
Participants of nutrition education classes sponsored by the State Cooperative Extension System are typically evaluated with a pencil-and-paper design.1,2 At the initial meeting, participants answer questions before any intervention. Such “testing” can generate apprehension among participants and foster an uninviting environment. The purpose of this research was to create an enjoyable first-tim...
The eVect of Wve diVerent food resources (Coccus hesperidum honeydew, honey-water, Lobularia maritima, Fagopyrum esculentum and water only) on the longevity, fecundity, and progeny Wtness of female Gonatocerus ashmeadi, an egg parasitoid of the glassy-winged sharpshooter (Homalodisca vitripennis) was investigated in the laboratory. Female G. ashmeadi survived 208–405% longer (up to 11.7 days lo...
in order to investigate of the effects of water stress on seed yield and gas exchange and to evaluate the relationship between source and sink in sunflower azargol variety, a split-plot factorial field experiment was conducted in 2008. in this experiment, water stress (no irrigation from 30 days after sowing till ripening) and irrigation (irrigation at -3 bar soil water potential) were consider...
background essential oils (eos) possess antibacterial properties and represent a natural source to treat infections and prevent food spoilage. their chemical composition might be affected by the environmental condition and the developmental growth stages of the plant. objectives the current study aimed to determine the variations in chemical compositions and antimicrobial activities of the eos ...
background: many microorganisms in midgut of mosquito challenge with their host and also other pathogens present in midgut. the aim of this study was presence of non-pathogens microorganisms like fungal flora which may be crucial on interaction between vectors and pathogens. } methods: different populations of anopheles stephensi were reared in insectary and objected to determine fungal flora...
