To evaluate the influence of citrate on the potential developmental toxicity of high doses of aluminum (133 mg/kg/day), three groups of pregnant Sprague-Dawley rats were given by gavage aluminum hydroxide (384 mg/kg/day), aluminum citrate (1064 mg/kg/day), or aluminum hydroxide (384 mg/kg/day) concurrent with citric acid (62 mg/kg/day) on gestational days 6 through 15. Control animals received ...
Aluminum (Al) is the third most abundant metal in earth crust, whose chemical form is mainly dependent on soil pH. The most toxic form of Al with respect to plants is Al3+, which exists in soil pH <5. Acidic soil significantly limits crop production mainly due to Al3+ toxicity worldwide, impacting approximately 50% of the world's arable land (in North-Eastern India 80% soil are acidic). Al3+ to...
Knowing how acid soils and aluminum in soils may limit the growth of Eucalyptus trees in plantations is important because these plantations grow in many tropical and subtropical regions. Seedlings of four vegetatively propagated Eucalyptus clones, E. grandis × E. urophylla 'GLGU9'(G9), E. grandis × E. urophylla 'GLGU12' (G12), E. urophylla × E. camaldulensis 'GLUC3' (G3) and E. urophylla 'GLU4'...
Muricidal behavior, weight, open-field activity, passive-avoidance learning, and learning of an eight-arm radial maze were assessed in Long-Evans hooded rats subjected as weanlings to 60 days of oral administration of aluminum hydroxide gel (Group AA) or tap water (Group NA). Measurement of brain aluminum content indicated that the groups did not differ significantly in neural incorporation of ...
Efforts to understand how plants respond to aluminum have focused on describing the symptoms of toxicity and elucidating mechanisms of tolerance; however, little is known about the signal transduction steps that initiate the plant's response. Here, we image cortical microtubules and quantify plasma-membrane potential in living, root cells of intact Arabidopsis seedlings. We show that aluminum d...
Because of high toxicity of hydrazine and its derivatives, many efforts are conducted to finding alternative for hydrazine in hypergolic fuels which meanwhile can do spontaneous ignition, has a low environment risk. Due to high reducing ability of hydrazine, usage of powerful conducing agents’ idea was interested. These conducting agents required to improvement in order to use as a hyperg...
This report reviews the safety of Aluminum, Calcium, Lithium Magnesium, Lithium Magnesium Sodium, Magnesium Aluminum, Magnesium, Sodium Magnesium, and Zirconium Silicates, Magnesium Trisilicate, Attapulgite, Bentonite, Fuller’s Earth, Hectorite, Kaolin, Montmorillonite, Pyrophyllite, and Zeolite as used in cosmetic formulations. The common aspect of all these claylike ingredients is that they c...
