Hyperphosphatemia is an independent risk factor for mortality and cardiovascular events in patients with chronic kidney disease (CKD). For patients who cannot control their serum phosphate levels adequately with diet, agents that limit gastrointestinal phosphate uptake are indicated. The use of phosphate-binding agents has changed over the years as more is learned about the mechanisms that unde...

abstract        background and objective: aluminum salts are among the most common useful additive compounds in preparation of human and animal vaccines. aluminum phosphate and aluminum hydroxide are two additives that show good immunoadjuvant effects with many antigens. aluminum-containing vaccines lead to a better and longer immune response compared to adjuvant-lacking vaccines. the chromogen...

A 3D porous aluminum(III) trisphosphonate, constructed from 1D inorganic aluminum phosphate chains and tripodal organic linkers, contains large hexagonal channels (1.24 nm in diameter) and a highly accessible void (50.3%) which allow it to have a fast and relatively high uptake of H2, N2 and CO2.

Sodium pyrophosphate (pyro-P, Na4P2O7), sodium tripolyphosphate (tripoly-P, Na5P3O10), and sodium hexametaphosphate (meta-P, (NaPO3)6) were selected as the model compounds of condensed phosphate to investigate the adsorption behavior of condensed phosphate on aluminum hydroxide. The adsorption was found to be endothermic and divisible into two stages: (1) fast adsorption within 1 h; and (2) slo...

High concentrations of arsenic have been detected in soils and underlying groundwater of some South Florida golf courses, indicating the possible impact of the application of arsenic-containing herbicides. The mobility of arsenic in the soils from selected golf courses was studied using a simple two-step sequential extraction procedure. Sodium nitrate (0.1 M), potassium dihydrogen phosphate (0....

GTPase-activating proteins (GAPs) function by stabilizing the GTPase transition state. This has been most clearly demonstrated by the formation of a high-affinity complex between various GAPs and GDP-bound GTPases in the presence of aluminum tetrafluoride, which can mimic the gamma-phosphate of GTP. Herein, we report that p190 RhoGAP forms a high-affinity complex with Rho GTPases in the presenc...

A self-powered electrocoagulation system with a single-chamber aluminum–air fuel cell was employed for phosphate removal in this study. Electricity production and aluminum hydroxides solution were also investigated. When the NaCl concentration increased from 2 mmol/L to 10 mmol/L, 86.9% 97.8% 60 min. An electrolyte composed of shown obtain maximum power density generation 265.7 mW/m2. initial p...

'Cleopatra' tangerine (Citrus reshni Hort. ex Tanaka) seedlings were irrigated daily for 8 weeks with 1/4 strength Hoagland's nutrient solution containing 0 (control) or 2 mM aluminum (Al). Leaves from Al-treated plants had decreased CO2 assimilation and stomatal conductance, but increased intercellular CO2 concentrations compared with control leaves. On a leaf area basis, 2 mM Al increased act...
