Compounds found in the urine represent the end products of metabolism and are the expression of the efficiencies or inefficiencies of this process. Nutritional status has a direct effect on this metabolic efficiency. Careful assessment of certain urinary compounds can yield valuable information on the nutrient needs of the individual. Urinary sulfate, asymmetric dimethylarginine (ADMA), and 8-h...

Drought is a serious environmental stress limiting growth and productivity in peanut and other crops. Nutrient uptake of peanut is reduced under drought condition, which reduces yield. The objectives of this study were to investigate nutrient uptake of peanut genotypes in response to drought and to estimate the relationship between nutrient uptake and peanut yield under different water regi...

Previous studies have demonstrated that populations differ from each other in size and proportion, and that these differences can affect metric assessment of sex. This paper establishes standards for determining sex from fragmentary and complete tibiae in the modern Croatian population. Measurements were taken on 180 tibiae (109 male and 71 female) from positively identified victims of the 1991...

OBJECTIVE We examined the association of nutrient intake with microstructural white matter integrity, and the role of white matter integrity in the association between nutrient consumption and cognition. METHODS This cross-sectional analysis included 239 elderly (age ≥ 65 years) participants of a multiethnic cohort. White matter integrity was measured with fractional anisotropy (FA) from diff...

Leaf nutrients of sugarcane variety N16 are discussed and reasons for certain trends put forward. The fertilised versus non-fertilised treatment comparison showed that although where fertiliser was applied that leaf N, P and K were higher, Mn was also higher but Ca, Mg, Si, Zn and Fe were all lower. The trashed versus burnt treatments had a less drastic effect on leaf nutrient levels and it was...

Lake Tanganyika’s many endemic species are under threat by impacts from human development and land use changes. Anthropogenic sediment inputs into the lake have increased, with a suite of negative effects on the benthic fauna. Sedimentation reduces habitat heterogeneity, alters cycling of nutrients, interferes with visibility, and interferes with photosynthesis. For fauna of the rocky benthos, ...

Human activities in the watersheds of the tributaries of Pamlico Sound (PS) in North Carolina have resulted in increased riverine loading of nutrients. Pamlico Sound is a regionally important aquatic resource, and provides crucial foraging and nursery habitats for Southeast Atlantic fisheries. Changes in phytoplankton community composition that may result from increased frequency and quantity o...

The U.S. government has conducted nationwide food consumption surveys since 1936. Information obtained from these surveys is used to design food assistance programs, guide food and nutrition policy, and monitor the dietary status of the population. The distribution of usual intakes of a nutrient in the population is of interest to policy makers. Here, usual intake is deened as the long-run aver...

Successional changes of terrestrial vegetation can profoundly influence stream ecosystem structure and function. We hypothesized that microbial enzyme production and community structure in stream beds depend on terrestrial litter inputs that reflect different stages of riparian succession. Outdoor experimental channels were supplied with leaf-litter of varying quantities and qualities to mimic ...
