Interactive Effects of Macronutrients on Obesity and Metabolic Syndrome Development
In the second study, male Sprague-Dawley rats (N=24) were fed one of 6 diets for 30 days. Diets were based on a 2x3 factorial with 2 levels of protein (P10 and P20, percent energy), and 3 levels of fructose (F0, F20, and F40, percent energy, replacing glucose). Body composition was measured at the …

Studies on the biological extraction of plant macronutrients from sewage effluents
Eutrophication of water supplies has necessitated the development of methods to prevent discharge of excessive quantities of nitrogen and phosphorus. Operation of a generally applicable process for removing these elements from sewage effluents has not yet been reported. The investigations described …

Effect of peat solidification on macronutrients in soils associated with palm oil plantation in peat area
Nutrients in the soil either from man-made fertilizers or natural are factors that affect the chemicals in the peat soil stabilization through leaching. The study aims to identify the concentration of elements and nutrients on peat solidification of cement (OPC), fly ash and bottom ash. Lab scale …

Changes in Dietary Intake, Macronutrients, Diet Quality, and Hunger Hormones after a 24-Week Diabetes Education Program Featuring Intermittent Energy Restriction or Time-Restricted Eating
Background: The effects of time-restricted eating with energy restriction (TRE+ER) and intermittent energy restriction (IER) on diet intake, quality, and hunger hormones (ghrelin, leptin) have not been compared in a parallel trial. This study examined how ghrelin and leptin relate to diet quality …

Comparison of Children's 24-Hour Recalls and Food Records Using Two Methods of Analysis
… POS-DAT) by converting food into energy and macronutrients. The reporting-error-sensitive method classifies items as matches, omissions, or intrusions and amounts as corresponding, over or unreported. Paired t-tests, correlation coefficients, report rates (reported amounts/reference amounts x …

Immune system status, select nutrient intakes, and micronutrient status in young women with a chronic suboptimal energy intake
… The SG consumed significantly lower intakes of macronutrients and several micronutrients than the CG (p<.05). Nutrient intakes in the SG, ≤70% of the RDA, were energy, carbohydrate, fat, vitamin D, calcium, iron, zinc, and copper; but only vitamin D and zinc in the CG. Zinc status and immune …

A role for HSC70 in regulating antigen trafficking and presentation during macronutrient deprivation
… lacking serum, which contains several types of macronutrients. Our studies show macronutrient stress amplified macroautophagy, favoring MHC class II presentation of cytoplasmic antigens targeted to autophagosomes. By contrast, macronutrient stress diminished MHC class II presentation of membrane …

Nutrients and their role in promoting cyanobacterial growth along the Murray River, Australia
… with phytoplankton is significant. The macronutrients nitrogen (N) and phosphorus (P) are known drivers of cyanobacterial growth, and micronutrients such as sulfur and the trace metals iron, cobalt and manganese can also influence bloom formation. This thesis examined what macronutrients …

Insect meals as novel protein sources in retorted pet food for adult cats
… apparent total tract digestibility (ATTD) of macronutrients, fecal scores and metabolites of adult cats fed insect- or chicken-based retorted diets. This study consisted of a complete randomized design, with 28 adult cats (mean age = 2.1 0.03 yr; mean BW= 4.9 0.8 kg) randomly assigned to 4 …

Investigating the Relationships Between Age and Depth of Stockpiled Topsoil with Its Nutrient Content: An Analysis of Responsible Factors and Potential Consequences
… Alberta. The samples were analyzed for pH, macronutrients, micronutrients, total organic carbon and organic matter. Descriptive statistics and correlation analysis were used to determine if there were significant chemistry changes between age and depth of stockpiled soils. The results …

Nutrient intakes of healthy adults on a gluten-free diet
… analysis software was used to evaluate intake of macronutrients and selected micronutrients. Gluten-free males consumed significantly lower amounts of carbohydrates, fiber, niacin, folate, and calcium but significantly higher amounts of fat and sodium than regular diet males. Gluten-free females …

Nutrient intake in college students in a midwestern regional university compared to the recommended dietary guidelines
… Intakes of total energy (kilocalories), macronutrients and key micronutrients were assessed from three-day food diaries maintained by participants and compared with the Dietary Reference Intake Standards. Results indicated that 4% of EMU students were underweight, 52% were within a normal …

Daily macronutrients (calories, protein, carbohydrate, fat and total sugar) intake were regressed on knowledge of MetS components presence and demographic characteristics using Ordinary Least Square model. The results show that having information that one …

Dissecting the Mechanisms and the Nutritional Requirements of the Expansion of Normal and Tumorigenic Intestinal Stem Cell Lineages in Drosophila melanogaster
… However, the precise requirement of individual macronutrients or micronutrients could not be investigated because a chemically defined food: CDF) consisting entirely of purified compounds was not available. We developed a new CDF media that permits CDFs with different nutrient compositions at …

Diatom Community Composition Shifts Driven by Coherent Cyclonic Mesoscale Eddies in the California Current System
… The older, offshore eddy was low in macronutrients, nitrate-limited, low in Fe, and lower in diversity, the last result largely driven by the relative abundance of a single <em>Rhizosolenia</em> species. <em>Rhizosolenia</em> accounted for over 50% of the diatom community in 5 out of …
