Influence of dietary nutrients on life history-related traits of black flies and mosquitoes
The sugar-feeding ecology of dipteran vectors has recently been targeted because it presents opportunities to inoculate common food sources for these dipterans with entomopathogenic bacteria as a means of controlling the population of host-seeking adult dipteran vectors. Whereas this approach to …

Duodenal and ileal digestibility of dietary nutrients and endogenous protein losses in pre- and post-weaning young dairy calves
… proteins is dependent on many physiological and dietary factors, flows of AA and CP at the ileum need to be determined in order to obtain accurate estimates of nutrient ileal digestibilities. Soy protein remains one of the most studied alternatives to milk proteins. Microbial-treated soy protein …

THE ROLE OF GUT METABOLITES ON REGULATION OF INTESTINAL IMMUNITY
… cells that induce various immune responses to dietary antigens, commensal bacteria, and pathogens. Maintaining homeostasis at this mucosal barrier requires stringent regulation of the immune responses, including mechanisms to convey information about environmental conditions. Dietary nutrients …

Impact of dietary modification on aflatoxicosis in poultry
… of aflatoxicosis and its interrelationships with dietary modifications in broiler chicks and ducks. Results of these studies emphasize the many factors that the severity of aflatoxicosis depends on, including animal species, age, presence of mycotoxin adsorbent, and concentration of major dietary …

Nutritional implications of coprophagy and cecal function in two microtine rodents (Microtus pennsylvanicus and Microtus pinetorum)
… It was concluded that coprophagy provided select dietary nutrients but was not critical for maximum energy or protein intake under these dietary conditions. Cecum removal decreased diet digestibility but did not significantly influence body weight dynamics since food consumption and passage rate …

Ruminal Nitrogen Recycling and Nitrogen Efficiency in Lactating Dairy Cattle
… models, utilized to predict MUN, corrected for dietary nutrients and some animal effects, and thus the observed effect of cow on MUN variation may reflect genetic selection decisions of animals with either poor or efficient urea transport. A second trial observed that MUN and PUN concentrations …

Thylakoid membranes from green plants affect appetite and promote body weight loss
… are affected by thylakoids. The digestion of dietary nutrients is prolonged after thylakoid supplementation, resulting in prolonged glucose and insulin responses. In the long run, fasting blood-glucose concentrations are also decreased. Thylakoids stimulate the release of the satiety promoting …

Diet, adaptation and the evolution of assortative mating in Ceratitis capitata
… of the consequences of alteration in specific dietary nutrients during the development of medfly larvae. Following this, similar selective pressures were used as the basis of experimental evolution of medfly populations reared on divergent developmental diets. Divergence between these …

Association between dietary intake, health status and nutritional status of children aged 6-23 months in Namwala and Mkushi districts of Zambia
… infant stimulation and nurturing, inadequate dietary nutrients and recurrent illnesses/infections which result in poor absorption of nutrients, poor cognitive development, growth failure and weight loss. These factors are common in developing countries such as Zambia where only 11% of children …

The Impact of Excess Nutrients, Fatty Acids or Glucose, on BeWo Placental Trophoblast Metabolic Function
… intrauterine environment high in circulating nutrients in pregnancies complicated by maternal obesity and diabetes mellitus has been well linked with the development of metabolic health disorders in the exposed offspring. Impairments in placental development, mitochondrial respiration, and …

An investigation of nutrition-dependent mRNA translation in Drosophila larvae
Dietary nutrients promote organismal growth via activation of cellular pathways that are necessary for cellular growth and division. However, upon conditions of nutrient scarcity, organisms ranging from yeast to mammals alter their metabolism to conserve nutrients and energy. One of the key …

Saturation and isomerization of dietary fatty acids influence nutrient absorption and metabolism in the chicken
… 7,657 kcal/kg, respectively. The influence of dietary fatty acids on the lipid composition of the intestinal brush border membrane (BBM) was studied in Experiment 2. Beginning at hatch, chickens were provided isocaloric diets, identified as being either a minimal-lipid (1% 18:2n6) basal diet …

Dissecting the Mechanisms and the Nutritional Requirements of the Expansion of Normal and Tumorigenic Intestinal Stem Cell Lineages in Drosophila melanogaster
… of nutrient absorption. We hypothesized that dietary nutrients can extrinsically regulate ISC properties. However, the precise requirement of individual macronutrients or micronutrients could not be investigated because a chemically defined food: CDF) consisting entirely of purified compounds …

Diet and risk of acute myocardial infarction in Bangladesh: The Bangladesh Risk of Acute Vascular Events (BRAVE) study
… however evidence on its determinants is sparse. Dietary risk explains about one-third of global mortality and is a most important modifiable risk factor for CHD. Although there is extensive evidence on diet and risk of CHD from western populations, this cannot be generalised to South Asian …

Influence of nutrition on the muscle transcriptome and ruminal microbiome in cattle
… can alter the animal's ability to utilize dietary nutrients. Several of these factors include the ruminal microbiome composition and epithelial tissue function, and nutrient provision in utero. The objective of this dissertation was to evaluate the effects of nutrition on these …

Nutritional evaluation of raw meat and whole prey diets for domestic and exotic cats
… (e.g., other species, whole prey diets) or other dietary ingredients (e.g., fiber sources and concentrations, micronutrients). The overall objective of this research was to evaluate raw meat and whole prey diets for use by domestic and captive exotic cats, including diet compositional analyses, …
