Prevention of age-related losses in muscle mass and strength is key to protecting physical capability in older age and enabling independent living. To develop preventive strategies, a better understanding is needed of the lifestyle factors that influence sarcopenia and the mechanisms involved. Existing evidence indicates the potential importance of diets of adequate quality, to ensure sufficien...
Losses of corals worldwide emphasize the need to understand what drives reef decline. Stressors such as overfishing and nutrient pollution may reduce resilience of coral reefs by increasing coral-algal competition and reducing coral recruitment, growth and survivorship. Such effects may themselves develop via several mechanisms, including disruption of coral microbiomes. Here we report the resu...
Haustoria of biotrophic rust fungi are responsible for the uptake of nutrients from their hosts and for the production of secreted proteins, known as effectors, which modulate the host immune system. The identification of the transcriptome of haustoria and an understanding of the functions of expressed genes therefore hold essential keys for the elucidation of fungus-plant interactions and the ...
Lettuce (Lactuca sativa L.), as a leafy vegetable, has considerable economic benefits. Although nowadays the tendency is to grow lettuce hydroponically, growers use different nutrients solutions for lettuce production and there is not an optimal nutrients solution for lettuce production in Iran. Therefore, an experiment was carried out to introduce the optimal solution out of current solutions ...
To promote the sequestration of blue carbon, resource managers rely on bestmanagement practices that have historically included protecting and restoring vegetated coastal habitats (seagrasses, tidal marshes, and mangroves), but are now beginning to incorporate catchmentlevel approaches. Drawing upon knowledge from a broad range of environmental variables that influence blue carbon sequestration...
Malnutrition is a major factor in the etiology, management and prognosis of persistent diarrhea in young children. Apart from inadequate energy intake, deficiencies of several specific nutrients have been implicated. Zinc is a micronutrient that appears to be of special interest, at least in some communities. Zinc deficiency has been documented in otherwise normal children. The risk of deficien...
Nitrogen (N) and phosphorus (P) are fundamental for plant biomass production in grasslands, often co-limiting, have become major freshwater pollutants. By factorially applying gradients of N P to field-based grassland mesocosms, we tested saturating thresholds uptake as nutrients increase whether simultaneous potentially additive growing-season demand reduces flows dissolved subsurface leachate...
The loss of considerable amounts of water-soluble nutrients in the sweat would have an important bearing on nutrition in the tropics and in hot humid seasons of the year in the temperate zone, provided these losses represented something more than a mere diversion of excretion from kidney to sweat glands. The possibility of such losses has stimulated considerable research in recent years, partic...
