The time and rate of plant nutrient absorption by bright tobacco
In the production of most farm crops, emphasis is placed on yield per acre. Other things being equal, the higher the yield er acre the lower the per unit cost of production. But in the case of flue-cured tobacco, emphasis is placed primarily on quality. Yield per acre is, of course important, but …

Saturation and isomerization of dietary fatty acids influence nutrient absorption and metabolism in the chicken
… in vitro absorptive rate of differing dietary nutrients were studied. Diets similar to those in Experiment 2 were offered to broiler chicks from hatch to 28 days of age. Intestinal membrane concentrations of palmitic and oleic acids were not affected by dietary treatment. Chickens receiving the …

Fruit chemical traits shape bat nutritional ecology: from basic science to applications
… the variability and associations between nutrients and secondary metabolites within ripe Piper sancti-felicis fruits, showing that intraindividual variation of chemical traits can surpass interindividual variation and associations between chemical traits are scale-dependent, varying in …

Does pubescence increase uptake of nutrient deposition on leaves?
… of the Proteaceae in the CFR facilitate both nutrient absorption and water retention on the leaf surface. Leaf hair distribution is expected to show a pattern relative to the higher levels of atmospheric nutrients with proximity to the coast. 3. We followed a three pronged approach, this …

Sodium and glucose transport across the in vitro perfused midgut of the blue crab, Callinectes sapidus Rathbun
… and (2) to elucidate the mechanism of glucose absorption across the midgut of C. sapidus and to assess its role in nutrient absorption. The transport processes across the gut tissues were studied with an in vitro perfusion technique. I demonstrated a net mucosal to serosal sodium transport …

A Molecular Basis for Macrophage Control of Enteric Nervous System Function
… length of the gastrointestinal tract to promote nutrient absorption. Interactions between intestinal macrophages and the enteric nervous system regulate gastrointestinal motility, yet we have an incomplete understanding of the molecular mediators of this crosstalk. Here we identify complement …

Colonization and succession of phytoplankton species in upwelling plumes off the Cape Peninsula
… were discussed in terms of cell size, growth, nutrient absorption and buoyancy.

Evaluation and Selection of a Bacillus based Direct-Fed Microbial Candidate for In situ Enzyme Production to Improve Gut Health Integrity, Bone Quality and Growth Performance in Poultry
… which increase digesta viscosity and reduce nutrient absorption in monogastric animals. As a result, the addition of exogenous enzymes in poultry feed has steadily increased to maximize nutrient utilization and maintain performance parameters with diets containing less digestible ingredients. …

The cystic fibrosis transmembrane conductance regulator and acid-base transporters of the murine duodenum
… minimize intracellular acidification and sustain nutrient absorption.

Spoken language understanding in a nutrition dialogue system
… enable efficient self-assessment of energy and nutrient consumption. We are interested in studying whether speech can lower user workload compared to existing self-assessment methods, whether spoken language descriptions of meals can accurately quantify caloric and nutrient absorption, and …

Removal of Cyanogenic Glycosides in Whole Flaxseed via Lactobacillaceae Fermentation
… respiratory systems and can also influence nutrient absorption from food. Thus, CGs should be removed from flaxseed. In this study, whole flaxseed (35 g, 340 g and 1 kg) was fermented with a consortium culture of Lactobacillaceae at 30 °C over 72 h. Concentrations of CGs (total HCN, …

Investigations into the effects of berry flavonoids on nutrient transport processes in Caco-2 enterocytes
… transporters, influencing the rate of intestinal nutrient absorption. The transcriptional effects and consequences of such interactions remained to be fully elucidated. To address this we carried out gene expression microarray analysis on intestinal Caco-2 cells treated with a flavonoid-rich berry …

Investigating the movement of intestinal intraepithelial lymphocytes using an organoid co-culture system
… intestinal epithelial cells, is the main site of nutrient absorption. It is continuously exposed to food antigens, and also several bacteria and microorganisms. Intestinal intraepithelial lymphocytes (IELs) are T cells that are interspersed between epithelial cells, above the basement membrane. …

Behavioral and genetic characteristics of intestinal cell lineages in health and disease
… of the crypt. While this system is crucial for nutrient absorption, any derangements in the proliferative cells can quickly lead to cancer. In this thesis, we sought to better understand the behavioral and genetic characteristics of the different cell types along the intestinal crypt, in a mouse …

The Physiology and Pharmacology of FGF21 in the Exocrine Pancreas
… of digestive enzymes in order to facilitate nutrient absorption upon feeding. This function is mainly carried by acinar cells that require strict regulation of protein processing and stress-related pathways such as the integrated stress response pathway (ISR). Genetic, chemical or traumatic …

Root-zone temperature effects on the nutrient uptake of horticultural crops
… known about the effects of supraoptimal RZT on nutrient absorption. In my first study, I determined the amount of phosphorus (P), zinc (Zn), and manganese (Mn) in tomato (Lycopersicon esculentum Mill. 'Jet Star'), muskmelon (Cucumis melo L. 'Gold Star'), and thornless honey locust (Gleditsia …

Evaluation of Nitrogen Sources, Starter Fertilizers, and Amendments for No-Till Corn Production
… by the use of starter fertilizer, and if a nutrient absorption enhancer (polyaspartic acid) could further improve starter fertilizer effectiveness. On average, ammonium-polyphosphate starter fertilizers increased the height (15%) and dry weight (30%) of young plants, and significantly …

Mycotrophy in loblolly pine
… association, known for its classic role in nutrient uptake, is shown to play an equally important role in the protection of seedlings against colonization by root-infecting fungi. This protection enhances the survival of seedlings. The survival of pine seedlings was tested in non-sterile and …

Ontogenesis of Peptide Transport and Morphological Changes in the Ovine Gastrointestinal Tract
Nutrient absorption is important in all stages of life. As the diet of an animal changes from birth on, morphological and biochemical adaptation can be anticipated in order to accommodate changing demands. The main focus of the present study was to examine the relationship between age and diet on …
