increases over controls were found when root segments were incubated in phosphorus solutions containing 10-3 A D)NP ancd at lowx temlperatture. The increased Pi in Al-roots did niot result in an increase in the total amounit of l)hosphorus incorporated into phosphorylated compounds. Aluminum treatnment miiarkedly decreased the incorporation of P32 into sigar phosl)hates but increased the pool s...

Phosphorus (P) is one of the most important elements used in fertilizing soils tropical regions due to low efficiency phosphate fertilization. This work aimed fractionate inorganic P (Pi) different mineralogical compositions and relate these fractions with their respective buffer capacity (PBC) indicators. The were characterized physically, chemically mineralogically. Additionally, we evaluated...

Aluminum is a ubiquitous element that is released naturally into the environment via volcanic activity and the breakdown of rocks on the earth's surface. Exposure of the general population to aluminum occurs primarily through the consumption of food, antacids, and buffered analgesics. Exposure to aluminum in the general population can also occur through vaccination, since vaccines often contain...

Auxin acts synergistically with cytokinin to control the shoot stem-cell niche, while both hormones act antagonistically to maintain the root meristem. In aluminum (Al) stress-induced root growth inhibition, auxin plays an important role. However, the role of cytokinin in this process is not well understood. In this study, we show that cytokinin enhances root growth inhibition under stress by m...

We synthesized Al-containing acidic and basic (alkaline) sodium aluminum phosphates (SALPs) which are FDAapproved leavening and emulsifying agents, respectively, and used them to determine the oral bioavailability of aluminum incorporated in selected foods. We selected applicable methods from published syntheses (patents) and scaled them down ( 3000and 850-fold) to prepare 300–400 mg of each SA...

In this study, both experimental and theoretical approaches, including absorption spectra, fluorescence emission spectra, 1H- and 31P-NMR, electrospray ionization mass spectrometry (ESI-MS), pH-potentiometry and theoretical approaches using the BEST & SPE computer programs were applied to study the competitive complexation between ciprofloxacin (CIP) and b-nicotinamide adenine dinucleotide phos...

A major effect of aluminum toxicity in plants is the disturbance of phosphorus assimilation. Wright (15) noted similar symptoms in beet plants grown in phosphorus-deficient media and in culture solution containing aluminum, while work at Aberystwyth (13) has shown that ryegrass lines resistant to aluminum toxicity require much higher levels of aluminum to dlevelop aluminunm toxicity/phosphorus ...

Background & Aims of the Study: Detergent and phosphate are one of the main and vital threats (eutrophication phenomenon and production of synthetic foam) for the source of drinking water, agriculture and industrial uses in the Ahvaz, Iran that threaten human health. The aim of this study is the evaluation of the efficiency of the electrocoagulation...

Release of reactive (phosphate-like) phosphorus (P) from freshwater sediments represents a significant internal P source for many lakes. Hypolimnetic P release occurs under reducing conditions that cause reductive dissolution of ferric hydroxide [Fe(OH)3]. This hypolimnetic P release may be naturally low or artificially reduced by sediment with naturally high or artificially elevated concentrat...
