Tumor-induced reduction in food intake in 2 rat-tumor organisms was distributed approximately equally between reduction in average size (premature satiety) and reduction in frequency (impaired perception of hunger) of effective meals. In both organisms, the frequency of futile meals (activity at food dish without any food ingestion) increased in the tumor-bearing state, and total meal frequency...

BACKGROUND Food insecurity not only affects physical growth and health of children but also their intellectual development, school attendance and academic performance. However, most evidences are based on studies in high income countries. Although food insecurity is common in Ethiopia, to what extent it affects school attendance and educational attainment of adolescents is not explored. We hypo...

Robust and balanced gut microbiota are required to support health and growth. Overgrowth of gut microbial or pathogens can change ecosystem balance, and compromise gut integrity to initiate gastrointestinal (GI) complications. There is no safe and effective modality against coccidiosis. Antibiotic additives routinely fed to food animals to protect against infection, are entered into the food ch...

Detection of genetically modified organisms (GMOs) in food is an important issue for all the subjects involved in food control and customer's right. Due to the increasing number of GMOs imported to Iran during the past few years, it has become necessary to screen the products in order to determine the identity of the consumed daily foodstuffs. In this study, following the extraction of genomic ...

OBJECTIVE The objective of the study was recognition of the opinions of adolescents completing secondary schools concerning genetically modified organisms and genetically modified food, especially the respondents' emotional attitude towards scientific achievements in the area of live genetically modified organisms. MATERIAL AND METHOD The study covered a group of 500 school adolescents comple...

Political responses to novel foods and crops can be specific to the new traits of those crops (agronomic versus enhanced nutrients), to the intended uses of those crops (food for people versus feed for animals), and also to the methods used to introduced those traits (conventional breeding versus genetic engineering). This article describes variations in observed political responses to three di...
