Nutrient labeling is found to significantly affect consumer purchase behavior; some evidence that consumers may act as if they hold nutrient (or health risk) budgets is found. Providing nutrient information may allow consumers to more easily switch consumption away from 'unhealthy' products in those food categories where differences in other quality characteristics (e.g., taste) are relatively ...

Genetic manipulations in nutrient-sensing pathways are known to both extend lifespan and modify responses to environmental stressors (e.g., starvation, oxidative and thermal stresses), suggesting that similar mechanisms regulate lifespan and stress resistance. However, despite being a key factor reducing female lifespan and affecting female fitness, male-induced harm has rarely been considered ...

Phosphorus and biologically active nitrogen are valuable nutrient resources. Bioremediation with macroalgae is a potential means for recovering nutrients from waste streams. In this study, reject water from anaerobically digested sewage sludge was successfully tested as nutrient source for cultivation of the green macroalgae Ulva lactuca. Maximal growth rates of 54.57±2.16% FW d(-1) were achiev...

Fetal growth is determined by many factors. These include genes, maternal nutrient supply, placental transport function, nutrient concentration gradient between maternal and fetal blood, placental blood flow, etc. Among these factors, gene determinants play an important role. Their mutation and expression are related to the perinatal growth phenotype [1-5]. In this review, perinatal growth phen...

Pervasive overharvesting of consumers and anthropogenic nutrient loading are changing the strengths of top-down and bottom-up forces in ecosystems worldwide. Thus, identifying the relative and synergistic roles of these forces and how they differ across habitats, ecosystems, or primary-producer types is increasingly important for understanding how communities are structured. We used factorial m...

Human activities have led to increased deposition of nitrogen (N) and phosphorus (P) into soils. Nutrient enrichment soils is known increase plant biomass rates microbial litter decomposition. However, interacting effects hydrologic position associated changes soil moisture can constrain activity lead unexpected nutrient feedbacks on community structure–function relationships. Examining decompo...

Spores of a Bacillus subtilis strain with a gerD deletion mutation (Delta gerD) responded much slower than wild-type spores to nutrient germinants, although they did ultimately germinate, outgrow, and form colonies. Spores lacking GerD and nutrient germinant receptors also germinated slowly with nutrients, as did Delta gerD spores in which nutrient receptors were overexpressed. The germination ...

The onset of estrus is a critical sign of female sexual maturity. The pituitary plays a vital role in this process by the secretion of reproductive hormones. To investigate the effects of nutrient restriction on reproductive function and the underlying mechanisms involved, deep RNA sequencing of pituitary gland tissue was carried out to determine the differentially expressed genes (DEGs) betwee...
