Current Opinion in Gastroenterology, 2001
Many advances in the study of nutrient absorption have been made with the use of molecular and genetic techniques; however, standard in vivo studies have provided interesting and important new information. Omega-3 long-chain fatty acids have unexpected effects on lipoprotein formation and secretion in neonatal intestinal cells; this needs to be ...

Current Opinion in Gastroenterology, 2000
Some key advances occurred last year in understanding mechanisms involved in nutrient absorption. A novel "prechylomicron transport vesicle" was identified; its movement to the Golgi is the rate-limiting step for triacylglycerol absorption. A scavenger receptor (type BI) in the brush border membrane appears to facilitate cholesterol uptake.

Nutrient efficiency along nutrient availability gradients
Oecologia, 1999The validity of nutrient use efficiency as a central concept in ecosystem ecology has recently been subject to challenge based upon arguments over autocorrelation of data, interpretation of graphical approaches, and appropriate statistical analyses. Much of the confusion on the measurement and interpretation of nutrient use efficiency results from the ...

Mitochondria in response to nutrients and nutrient-sensitive pathways
Mitochondrion, 2010Mitochondria are abundant cellular organelles, and are required for the generation of energy through oxidative catabolism. Equally important, mitochondria also provide substrates for de novo synthesis of fatty acids and multiple amino acids. Mitochondrial functions must therefore be tightly linked to cellular nutrient availability.

Our understanding of nutrient absorption continues to grow, from the development of unique animal models and from studies in which cutting-edge molecular and cellular biologic approaches have been used to analyze the structure and function of relevant molecules.

PLACENTAL TRANSPORT OF NUTRIENTS
Obstetrical & Gynecological Survey, 1976The fetus is dependent upon the placenta for transport to it of all nutrients for energy and growth. The primary nutrients crossing the placenta are glucose, lactic acid, free amino acids, free fatty acids, and ketone bodies. Under normal circumstances, it appears that glucose is the primary energy source.

Nutrition Reviews, 2012
Nutrient intake recommendations, unlike hormone replacement standards, are based empirically, rather than physiologically, i.e., they lack an a priori normal referent. Randomized controlled trials do not provide the needed referent and are unlikely to distinguish between fully normal and various suboptimal nutritional states.

Proposing nutrients and nutrient levels for rice fortification
Annals of the New York Academy of Sciences, 2014Micronutrient deficiencies are often linked to low dietary diversity. Rice fortification could substantially increase micronutrient intake in countries where rice is a staple food. The World Health Organization (WHO) interim consensus statement on maize and wheat flour fortification is based on the premise of the public health importance of specific ...

Nutrient Levels and Nutrient Sources in Pancreatic Tumors
Cancer ResearchAbstract It has been known that poor tumor perfusion and dysregulated cancer cell metabolism give rise to tumor microenvironments with unphysiologic nutrient levels, but the precise alterations in metabolite abundance are not well defined.
