Observational studies and randomized controlled trials have produced divergent results concerning the effect of hormone replacement therapy (HRT) on cardiovascular disease and, to a lesser extent, dementia. Residual confounding (confounding that remains even after adjustment for various socioeconomic and lifestyle factors) is one explanation that has been offered for these divergent results. Th...
Ruminant phosphorus excretion and metabolism were studied through a database. Faecal endogenous phosphorus is the main pathway of phosphorus excretion and averages 0.85 of total faecal phosphorus. The remaining 0.15 is unabsorbed dietary phosphorus. Faecal endogenous phosphorus is mainly unabsorbed phosphorus, with saliva being the major source, and is correlated to factors influencing saliva s...
Selective solid-phase reduction of iron and phosphorus in oolite ores the Lisakovsky Ayat deposits was experimentally studied. Using X-ray phase analysis, composition initial samples after roasting determined. Goethite, magnetite quartz were found both deposits. Phosphorus ore deposit is form aluminum phosphate hydrophosphate, – as a component calcium hydrophosphate. Experiments on carried out ...
Arabidopsis thaliana root hairs grow longer and denser in response to low-phosphorus availability. We tested the hypothesis that wild-type Arabidopsis would acquire more phosphorus under phosphorus-limiting conditions than mutants that do not have the root hair response. The growth and phosphorus acquisition of wild-type Arabidopsis (WS) were compared to two root hair mutants (rhd6 and rhd2) un...
Atherosclerotic calcifications are related to poor prognosis and all-cause mortality in large population studies.1 Moreover, vascular calcifications are inversely associated with the potential reduction of plaque volume in regression studies during statin treatment, which suggests that more calcified lesions are less likely to undergo positive remodeling.2 Recently, it has been suggested that c...
Arabidopsis thaliana root hairs grow longer and denser in response to low-phosphorus availability. In addition, plants with the root hair response acquire more phosphorus than mutants that have root hairs that do not respond to phosphorus limiting conditions. The purpose of this experiment was to determine the efficiency of root hairs in phosphorus acquisition at high- and low-phosphorus availa...
In acid soils, soluble inorganic phosphorus is fixed by aluminium and iron. To overcome this problem, acid soils are limed to fix aluminium and iron but this practice is not economical. The practice is also not environmentally friendly. This study was conducted to improve phosphorus availability using organic amendments (biochar and compost produced from chicken litter and pineapple leaves, res...
