Aluminum compounds were first identified as adjuvant over 90 years ago [1]. Adjuvants (immunopotentiators or immuno modulators) in vaccine formulations aim to enhance, accelerate and prolong the specific immune response towards the desired response to vaccine antigens. Advantages of adjuvants include the enhancement of the immunogenicity of antigens, modification of the nature of the immune res...

In Spain, the secondary aluminum industry is a mature activity which produces 35% of the total aluminum production. This industry generates slag (black dross) with a valuable content of aluminum which is recovered by dry milling processes in the aluminum tertiary industry. The powdered fine solid is trapped in the sleeve filter suction system of the aluminum slag milling process. This solid is ...

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 ...

Pea (Pisum sativum) roots were treated with aluminum in a calcium solution, and lipid peroxidation was investigated histochemically and biochemically, as well as other events caused by aluminum exposure. Histochemical stainings were observed to distribute similarly on the entire surface of the root apex for three events (aluminum accumulation, lipid peroxidation, and callose production), but th...

Aluminum is a common contaminant in many components of parenteral nutrition, especially calcium and phosphate additives. Although long-term effects have been described in the literature, short-term effects are not well-known. Currently, the Food and Drug Administration recommends maintaining aluminum at <5 mcg/kg/day. This was a single center, retrospective case-control study of 102 neonatal in...

Inorganic aluminum ions, [Al(H2O)6]3+, [Al(OH)(H2O)5]2+, and [Al(OH)2(H2O)4]+, are toxic to a number of crops. The aim of this study was to estimate the danger of soil contamination of bioavailable aluminum and heavy metals forms because of alum sludge which was a by-product of water, and wastewater treatment technology using aluminum coagulant is introduced into the soil. Aluminum and selected...

Polynuclear Pd(II) complexes with biogenic polyamines present great potential clinical importance, due to their antiproliferative and cytotoxic activity coupled to less severe side-effects. The adsorption process and the redox behaviour of two polynuclear palladium chelates with spermine (Spm) and spermidine (Spd), Pd(II)-Spm and Pd(II)-Spd, as well as of their ligands Spm and Spd, were studied...

Three different zirconium thio and oxothio clusters, characterized by different coordination modes of dithioacetate and/or monothioacetate ligands, were obtained by the reaction of monothioacetic acid with zirconium n-butoxide, Zr(O(n)Bu)4, in different experimental conditions. In particular, we isolated the three polynuclear Zr3(μ3-SSSCCH3)2(SSCCH3)6·2(n)BuOH (Zr3), Zr4(μ3-O)2(μ-η(1)-SOCCH3)2(...

Copper complexes obtained from the reactions between 2-thiouracil and cupric hydroxide in different solvents have been investigated. Mononuclear or polynuclear complexes of Cu(I) have been obtained depending on the reaction conditions. Hydroxo complexes of copper(I) have been obtained at pH around 3.5. 2-Thiouracil acts as monoor bidentate ligand in complexes. [Cu(H2TU)2 OH], [Cu5(H2TU)6 (OH)5]...
