The effects of exercise and dietary iron on iron status in 13 months old female rats
… was to investigate the effects of exercise and dietary iron on various components of iron metabolism in 13 month old female rats. Fifty-six 13 month old female Sprague-Dawley rats were randomly assigned to one of five groups of treatment: baseline (BL); 40ppm iron, exercise (40 E); 9ppm iron, …

The effects of exercise and dietary iron on iron status in 19 month old adult female rats
… study investigated the effects of exercise and dietary iron on iron status in 19-month-old female rats. Fifty-seven female Sprague-Dawley rats were randomly assigned to one of five experimental groups: baseline (BL); iron sufficient-exercise (HE); iron sufficient-sedentary (HS); moderate iron …

Effects of Prepartum Energy and Protein Density on Productivity and Influence of Dietary Iron on Copper Status of Holstein and Jersey Cattle
… postpartum. Prepartum DMI increased linearly as dietary energy density increased. Non-esterified fatty acids did not differ for energy density and were greater for Holsteins. Milk and 4% FCM increased linearly as dietary energy density increased, although postpartum DMI was quadratic for energy …

Folate status and milk folate concentration in lactating women
… species have demonstrated a relationship between iron deficiency and impaired milk folate secretion. Objectives of this study were to monitor the folate status of lactating women and to examine the relationship among folate intake, dietary iron, folate status, iron status and milk folate. …

Iron and its Relationship to Neural Tube Defects among Offspring of Texas Border County Women
… explored whether an association existed between iron and NTDs in 148 cases and 158 controls. Dietary iron intake, blood hemoglobin and hematocrit values, and serum ferritin values were analyzed to see whether case and control values differed. No associations were found between case-women and …

Effects of Nutrients and Minerals on Growth and Detoxification in Phytophagous Insects
… insects to utilize a hostplant. One way dietary deficiencies of these compounds may reduce insect performance is by affecting activities of detoxification enzymes, thereby altering susceptibility to host plant allelochemicals. In this study I examined the influence of antioxidant …

The potential role of interleukin-2 in impaired cell-mediated immunity of iron deficiency
Iron deficiency impairs cell-mediated immunity, which is primarily dependent on T-lymphocyte functions including production of the cytokine, interleukin 2 (IL-2). The potential role of IL-2 production and responsiveness in impaired cell-mediated immunity of iron deficiency was investigated in a …

The Fumonisin B1-Fed Rat as a model for liver injury, oval Progenitor') cell proliferation, and carcinogenesis
… of liver tumours, possibly by providing an environment that selects for the growth ofTGF-~1-resistant transformed liver cells. In rats given FBI in the presence of dietary iron overload, FBI augmented iron-induced lipid peroxidation in the liver. However, dietary iron loading appeared to …

The fumonisin B₁-fed rat as a model for liver injury, oval ('progenitor') cell proliferation, and carcinogenesis
… of liver tumours, possibly by providing an environment that selects for the growth of TGFβ1-resistant transformed liver cells. In rats given FB₁ in the presence of dietary iron overload, FB₁ augmented iron-induced lipid peroxidation in the liver. However, dietary iron loading appeared to …

Longitudinal effects of early-life iron status in pigs
Iron deficiency is reported as the most common nutrient deficiency worldwide. Due to rapid growth and low iron stores at birth, infants are at particular risk for developing iron deficiency. Further, iron deficiency is known to affect the developing microbiota. Thus, the aim of this study was to …

The Effect of Iron Overload on the Long-term Toxicological Effects of Fumonisin B1 in Rat Liver
The long-term toxicological effects of hepatic iron overload on the cancer initiating and promoting properties of fumonisin B1 (FB1) were investigated in male Fisher 344 rats. An initial pilot (dose response) study over 15 weeks was performed to determine a level of dietary iron that achieves a …

Novel Applications of Syndemic Theory for Global Public Health: Considerations for Gender Based Violence and Mixed Methods Research
… partner violence, depression, and inadequate dietary iron intake, which interact synergistically to magnify the probability of child health disparities (in this case, diarrheal disease). In Aim 3, I drew on a synthesis of qualitative and quantitative GBV syndemics literature from LMICs and …

Resistance to HER2-targeted therapies in HER2-positive breast cancer
… an increase in proteins associated with cellular iron homeostasis. Further investigation revealed increased heme oxygenase-1 (HO-1), iron exporter ferroportin and altered iron storage. To ascertain if modulation of dietary iron intake could affect the development of resistance to sapatinib, mice …

Assessment of early-life choline and iron deficiencies on neurodevelopment in the young pig
… influences neurodevelopment. Choline and iron are two micronutrients that are known to play pivotal roles in brain development, yet insufficient dietary intake remains a problem worldwide. The pig has emerged as an important translational model for studying neurodevelopmental outcomes …

Molecular responses of iron regulatory proteins to iron overload in human liver
Iron is one of the most abundant metals in nature and a necessary element for life. It is not iron per se but rather its implication in the generation of reactive oxygen species that makes the metal harmful when present in excess as seen in iron overload disorders, such as in hereditary …

The effects of exercise on iron metabolism in adult female rats
The effects of exercise training and iron intake on iron metabolism in adult female rats were investigated. Adult female Sprague-Dawley rats were assigned to either an exercise (E) or sedentary (S) group and fed either a diet containing 9 ppm (9) of dietary iron (low iron level), or 40 ppm (40) of …

Iron deficiency in blood donors: causes, symptoms, and mitigation strategies
… The absence of pre-donation testing for iron status allows many donors with iron deficiency to donate blood. This dissertation seeks to enhance our understanding of the causes of iron deficiency among blood donors, the resultant symptoms, and the likely effectiveness of alternate …

Effects of Maternal Iron Deficiency During Reproduction on Phagocytosis, Antibody Formation and Cell Growth in the Suckling Rat (Immune Response)
The effects of maternal dietary iron deficiency during reproduction on the development of the immune response in offspring were investigated. Pregnant Sprague/Dawley rats were fed one of three diets throughout gestation and lactation: 6 ppm iron (severe anemia), 12 ppm iron (moderate anemia), 250 …

Nutrients Analysis of Preschool Lunch Menus in Virginia
… to assess if they meet the national Recommended Dietary Allowances (RDAs) standards for vitamin A, vitamin C, calcium and iron. Lunch menus for 3-5 year old children were collected from 114 CACFP staffs attending a state wide CACFP menu training session. Fifty-seven weekly menus were selected …

Dietary intake in relation to iron status in 5-12 year old primary school children and estimated cost of a nutrient rich diet
… with half of the cases estimated to be due to iron deficiency (ID). School-age children are at high risk of these nutritional disorders due to their increased nutrient requirements, accelerated physical and intellectual development, but poor dietary intake. It is generally accepted that …
