A general saturation equation is derived which is shown to describe a wide variety of nutrient-response relationships in higher organisms. Iterative multiple linear regression analysis is used to obtain least squares estimates of the constants defining theoretical nutrient-response curves. Curves thus generated accurately predict experimentally observed responses. From this treatment, response ...

Environmental factors such as nutrition and housing can influence behavioral and anatomical characteristics of several neurological disorders, including Rett syndrome (RTT). RTT is associated with mutations in the X-linked gene encoding MeCP2, a transcriptional repressor that binds methylated DNA. While direct genetic intervention in humans is impossible at this time, motor and cognitive defici...

This study aims at testing a theoretical model explaining why people follow healthy eating habits and in particular to identify how the nutritional labels use influences this behavioural pattern. The results indicate that the individuals who utilise more often the nutritional labels follow healthier eating habits, such as avoiding snacking between meals, a lower intake of salt and avoiding the ...

PURPOSE This study examines the direct and indirect relationships between individual components of nutritional risk and increased severity of disability among a large and diverse sample of homebound older adults. DESIGN AND METHODS Using routinely collected nutrition and function data, structural equation modeling of recursive and nonrecursive models examined the interrelationships of nutriti...

Cholestatic liver disease (CLD) in children negatively affects nutritional status, growth and development, which all lead to an increased risk of morbidity and mortality. This is illustrated by the fact that the clinical outcome of children with CLD awaiting a liver transplantation is in part predicted by their nutritional status, which is integrated in the pediatric end-stage liver disease mod...

OBJECTIVES The aim is to explore the effects of antecedent, structural and process quality indicators of nutritional care practice on meal satisfaction and screened nutritional status among older adults in residential care homes. DESIGN Data for this Swedish cross-sectional study regarding older adults living in residential care homes were collected by i) a national questionnaire, ii) records...

OBJECTIVES To assess the dietary habits of Balearic Islands' consumers who are successful in meeting current nutritional recommendations, to find clues for the development of future food-based dietary guidelines (FBDG) that would be relevant to this population. DESIGN Cross-sectional nutritional survey carried out in the Balearic Islands between 1999 and 2000. SUBJECTS AND METHODS Dietary h...

Viviparous reptiles have been used as model species for many studies that seek to explain the evolution of viviparity. The vast majority of such studies have focused on the advantage viviparity provides with regards to maternal control of embryonic developmental temperature. However, viviparity may also allow increased control of nutrient transfer, such that mothers adaptively manipulate offspr...
