Phosphorus use and excretion varies with ploidy level inDaphnia

Sensitivity to phosphorus limitation increases with ploidy level in a New Zealand snail.

Evolutionary and ecological factors that explain natural variation in ploidy level remain poorly understood. One intriguing possibility is that nutrient costs associated with higher per-cell nucleic acid content could differentially influence the fitness of different ploidy levels. Here, we test this hypothesis by determining whether access to phosphorus (P), a main component of nucleic acids, ...

Assessment the relationship between phosphorus and magnesium, serum level with clinical outcome in head trauma patients

Background Traumatic brain injury is the second leading cause of death in Iran. Having knowledge of the factors affecting the clinical outcomes of these patients can improve the therapeutic outcomes. Objective The aim of this study was to determine the relationship of phosphorus (P) and magnesium (Mg) serum levels during admission with clinical outcomes of patients with head trauma. Methods T...

24-hour urine phosphorus excretion and mortality and cardiovascular events.

BACKGROUND AND OBJECTIVES Higher morning serum phosphorus has been associated with cardiovascular disease (CVD) in patients with or without CKD. In patients with CKD and a phosphorous level >4.6 mg/dl, the Kidney Disease Improving Global Outcomes guidelines recommend dietary phosphorus restriction. However, whether phosphorus restriction influences serum phosphorus concentrations and whether di...

Decreasing Nitrogen and Phosphorus Excretion by Dairy Cattle

In 1996, the Council for Agricultural Science and Technology (CAST) published a report entitled Integrated Animal Waste Management. One of the recommendations in that report was to “change animal diets to decrease nutrient outputs” (CAST 1996, 1). Since that time, concentration of animal production units has continued, public concern about the environmental effects of animal manure has increase...
