ADSORPTION OF PITCH AND STICKIES ON MAGNESIUM ALUMINUM HYDROXIDES TREATED AT DIFFERENT TEMPERATURES. Guodong Li a,b and Wenxia Liu a,*. Magnesium aluminum hydroxides (MAH) of nitrate and carbonate forms were prepared by co-precipitation, dried at different temperatures, and employed as an adsorbent for pitch and stickies in papermaking. Results indicated that MAH that had been heat-treated had higher adsorption capacity to model pitch and stickies at neutral pH. Low-temperature-dried magnesium aluminum hydroxides of nitrate form (MAH-NO3) had higher adsorption capacity to model pitch and model stickies than those of the carbonate form (MAH-CO3). Increasing the drying temperature of MAH reduced the difference of adsorption capacity between MAH-NO3 and MAH-CO3. Higher-temperature-dried magnesium aluminum hydroxides also showed higher adsorption capacity to model pitch and stickies when the drying temperature was lower than 550 oC. MAH displayed higher adsorption capacity while a lower initial ...

Aluminum is a naturally abundant element, the third most common element of the earths crust. It is naturally released to the environment from the weathering of rocks and volcanic activity. Aluminum present in surface waters due to man-made applications cannot be distinguished from natural aluminum released during weathering of aluminum-bearing minerals. The emission of the registered substance reaction mass of aluminium hydroxide and aluminium nitrate and aluminum sulphate is very low and mainly applies to (waste) water. If released into the environment, the substance will hydrolyse to aluminium hydroxide and precipitates in aquatic system or deposits as aluminium oxide in sediment or soil. Aluminum salts are used as coagulants and flocculants to cause fine materials that are suspended, soluble or both to agglomerate, for subsequent removal via sedimentation and filtration. As part of this agglomeration or coagulation process, most of the aluminum associated with the added aluminum salt ...

Most purified protein and peptide antigens are poorly immunogenic so adjuvants must be included in vaccines to activate and direct adaptive immune responses. The most commonly used adjuvants in clinical use are aluminium salts, particularly aluminium hydroxide adjuvant, which is chemically crystalline aluminium oxyhydroxide 1, 2 and comprises nanoparticles that form porous aggregates of 1-20 μm in diameter 2. Although not technically correct, aluminium-containing adjuvants are generally referred to as alum. Alum is not an optimal adjuvant for all protein antigens and is a relatively poor inducer of cell-mediated immunity. As a result, other particulate adjuvants, including chitosan, liposomes and biodegradable microparticles and nanoparticles are being investigated 3. However, despite the widespread use of particulates in both clinical and research settings for over 80 years, their mode of action is still not fully understood.. In 2007 it was found that aluminium-containing adjuvants enhanced ...
There are no studies available on terrestrial plants for the registered substance reaction mass of aluminium hydroxide and aluminium nitrate and aluminium sulphate. Nevertheless, aluminium is the most abundant metallic element in the Earths crust. Based on its ubiquitous occurrence the present natural background concentration far outweighs anthropogenic contributions of aluminium to the terrestrial environment. As detailed in the endpoint summary on terrestrial toxicity in general further toxicity testing on terrestrial organisms is considered unjustified and waiving based on exposure consideration is applied. However, for reasons of completeness existing data on the terrestrial toxicity of aluminium are provided in addition and summerised here. Kinraide & Parker (1987) in a test with Triticum aestivum determined an EC50 of 1.2 µM referring to the inhibition of root elongation of shoots after 2 days exposure. In a study investigating the same effect but using Alium cepa as test organism and a ...
Unfortunately, Merck, the manufacturers of this adjuvant have not made it available for any independent analyses, never mind safety testing. The visual evidence of the toxicity of aluminium adjuvants at the injection site is limited by their intramuscular administration (the adjuvant is hidden away in the muscle tissue) while their actual injection site toxicity is experienced by many as significant muscular pain, and associated events, in the receiving limb which can last for hours and even days. However, the role of the injection site toxicity is to attract a variety of immune-responsive cells and these cells proceed to load up their cell cytoplasm with particles of aluminium adjuvant as well as antigen, the latter may or may not be associated with the adjuvant material. Thereafter, dogma dictates that the delivery of antigen to lymph nodes initiates antigen-specific adaptive immunity. ...
Vaccines are frequently administered together with an adjuvant, a compound that boosts the immune response to the vaccines active ingredient. One of the most popular adjuvants is aluminium hydroxide, or alum, which has been used for 80 years or so, because it works. How it works was not known - until now. Aluminium salts are shown to activate the Nalp3 inflammasome, an intracellular innate immune response system active in macrophages. Understanding how this widely used adjuvant acts could help in the design of more powerful, more specific adjuvants working in the same way. The mechanism by which the widely used vaccine adjuvant alum acts on the immune system has been unclear to-date. This paper shows that alum-mediated stimulation of the adaptive immune response requires activation of the Nalp3 inflammasome in antigen presenting cells. Aluminium adjuvants, typically referred to as alum, are the most commonly used adjuvants in human and animal vaccines worldwide, yet the mechanism underlying the
The immune system represents a promising novel target for prevention of atherosclerosis. Several pilot vaccines that reduce atherosclerosis in experimental animals have been developed. The aluminum hydroxide adjuvant Alum has been shown to have antiatherogenic properties in itself, suggesting that it may be a suitable adjuvant in possible future atherosclerosis vaccines. To characterize the immune pathways mediating this protection, we treated wild-type C57BL/6 and Apoe(-)(/)(-) mice with Alum or PBS. Analyses of splenocytes isolated from 12-week-old mice demonstrated that Alum increased the presence of CD4(+)CD25(+)FoxP3(+) regulatory T cells and downregulated the expression of T cell activation markers CD28 and ICOS in Apoe(-)(/)(-) mice but not in C57BL/6 wild-type mice. A similar immunosuppressive phenotype was found also in 25-week-old Apoe(-)(/)(-) mice and was associated with reduced atherosclerosis. Alum precipitates recovered from the injection site of Apoe(-)(/)(-) mice contained ...

A method of treating lake water to remove suspended solids and to precipitate and inactivate phosphorus comprises adding aluminum hydroxide sulfate to the water in a concentration such that the pH of the water is maintained at a level of greater than 6.0 and precipitation of suspended solids and precipitation and inactivation of phosphorus occurs. This invention is advantageous in that it provides a method of removing suspended solids as well as precipitating and inactivating phosphorus in water while simultaneously preventing the solublizing of toxic amounts of aluminum into the water with subsequent detrimental effects to aquatic life.

Many currently licensed and obtainable human being vaccines contain light weight aluminum salts as vaccine adjuvants commercially. salts and high concentrations of trehalose only or an assortment of sugar and proteins as excipients can convert vaccines including light weight aluminum salts into dried out powder but does not protect the particle size and/or immunogenicity from the vaccines. In todays research using ovalbumin like a model antigen adsorbed onto light weight aluminum hydroxide or light weight aluminum phosphate a commercially obtainable tetanus toxoid vaccine adjuvanted with potassium alum a human being hepatitis B vaccine adjuvanted with light weight aluminum hydroxide and a human being papillomavirus vaccine adjuvanted with Fudosteine light weight aluminum hydroxyphosphate sulfate it had been demonstrated that vaccines including a comparatively high focus of light weight aluminum salts (we.e. up to ~1% w/v of light weight aluminum hydroxide) Fudosteine could be changed into a ...

In combination with elevations of serum or urine aluminium ranges, numerous research have demonstrated elevated levels of aluminium during the Mind right after oral 27Al publicity, demonstrating oral aluminium absorption. Some illustrations stick to. Rats and canines were being fed 300 or 3000 mg aluminium hydroxide day by day inside their food for 5 months. These animals exhibited a big elevation of Mind aluminium concentrations, in comparison with All those not getting the aluminium hydroxide (Arieff et al., 1979). A big elevation of brain aluminium was claimed just after a single administration of oral aluminium hydroxide to mice (Cutrufo et al., 1984), While these authors didnt report their genuine benefits. Rat bone, although not Mind, aluminium was substantially elevated following intake for 8 weeks of a diet plan containing 570 mg sucralfate/kg. Sucralfate is usually a sucrose aluminium sulphate elaborate ...

Are aluminum adjuvants plus Gardasil a uniquely damaging neuroinflammatory cocktail? By CLAIRE DWOSKIN Childrens Medical Safety Research Institute Health
Vaccine damage via adjuvants.. Although in contemporary vaccine history, aluminium adjuvants have been portrayed as inherently safe (Offit and Jew, 2003), studies in animal models and humans have demonstrated their ability to inflict immuno-inflammatory conditions by themselves (Authier et al., 2001; Petrik et al., 2007; Couette et al., 2009; Israeli et al., 2009; Shaw and Petrik, 2009; Gherardi and Authier, 2012).. There is no legal or medical requirement to demonstrate that aluminium adjuvants are without risk for human use and there is no approval mechanism. Only vaccines are approved for human use. There are two commonly used aluminium adjuvants, Alhydrogel® and AdjuPhos®, as well as a sulphated version of the latter, which is included in Gardasil, a vaccine against the human papilloma virus (HPV). Mercks own safety trial data suggest a frequency of adverse events for the vaccine of approximately 2.5% and similarly 2.5% for their placebo group who received their proprietary adjuvant. ...
Vaccines against pneumococcal disease for use in developing countries should be safe, effective against a broad range of serotypes and affordable. The existing conjugate vaccines offer protection against the serotypes included in the vaccine which were selected based on their prevalence in North America and Europe, and are predicted to provide incomplete protection against pneumococcal infections in Asia and Africa. In addition, these conjugate vaccines are expensive to produce. The work in this report demonstrates that a vaccine composed of killed whole cell, nonencapsulated pneumococci and formulated with AH, induces a strong antibody and IL-17 response. Both the antigen and adjuvant are relatively inexpensive suggesting that the vaccine will be affordable for use in developing countries.. Previous work with a simple protein antigen, alpha casein, indicated that the strength of adsorption of antigens onto aluminum-containing adjuvants is inversely related to the antibody response to these ...
Alum is applied to lake water as aluminum sulfate, or Al2(SO4)3 · 14 H2O. As aluminum sulfate is added to water, it forms aluminum ions, which are hydrated (combined with water):. Al+3 + 6 H2O ⇄ Al (H2O)63+. In a series of chemical hydrolysis steps, hydrogen ions are liberated, which may lower the water pH, and ultimately forms aluminum hydroxide (Al(OH)3), which is a solid precipitate:. Al3+ + H2O ⇄ intermediate reactions ⇄ Al(OH)3(s) + H+. The solid precipitate forms a flocculent material, referred to as a floc, that has a high capacity to adsorb phosphates. The aluminum hydroxide blanket, when applied appropriately, separates the sediment from the water column, which reduces internally supplied phosphorus.. Free aluminum may persist at pH less than 6 or other hydroxides may form at pH greater than 9; although toxicity may occur at pH , 8 in some conditions. Both forms may be toxic to aquatic life. As a practical matter, the use of buffered alum has mitigated this concern by controlling ...
An additional testing report shows that Merck tested Gardasil against an aluminum-containing placebo. While most placebos are saline based, the FDA allowed Merck to use a placebo with an undisclosed amount of aluminum in it. Gardasil itself contains 225 mcg of aluminum. Aluminum can cause many serious problems including temporary and permanent nerve damage. Using a reactive aluminum-containing placebo instead of a non-reactive saline base can make vaccines seem safer than they may actually be. While Merck has repeatedly stated that Gardasil is on a comparable safety rate with the placebo, if the placebo itself is responsible for adverse effects then it is more difficult to ascertain the vaccines safety. Mercks testing report shows charts of clinical tests, and compares Gardasil with the aluminum-containing placebo. It is true that the adverse reaction rates are comparable in most of the tests, but since the vaccine is being tested against a reactive, potentially harmful substance, the numbers ...

Aluminum hydroxide is used to reduce hyperphosphatemia (elevated blood levels of phosphate) in patients with kidney failure. Aluminum salts work by reducing the amount of phosphorus absorbed from the intestine by physically binding to dietary phosphorus.. Normally, the kidneys filter out any excess phosphorus from the body, but when the kidneys are failing, phosphorus will accumulate in the blood. Elevated phosphorus levels in the blood are associated with lethargy and poor appetite. In some cases, phosphorus levels can be controlled through the use of a special diet formulated for kidney disease. When dietary restriction alone is not sufficient to control the elevated blood phosphate levels, aluminum hydroxide is used to reduce the amount of phosphorus absorbed from the intestines. Controlling hyperphosphatemia has been shown to increase the lifespan of animals with chronic kidney failure.. ...
pathogen are appallingly low. Biofilm is an important virulence factor and immunogenic structure of S. aureus that makes it resistant to phagocytosis and antibiotics. Reports on the efficacy of vaccine prepared from a biofilm producing S. aureus are infrequent. The present study was designed to evaluate the role of a bacterin-toxoid prepared from a strong biofilm producing S. aureus in effective immunization of rabbits. The strong biofilm producing S. aureus selected from 64 isolates of staphylococci was used to prepare bacterin-toxoid and aluminum hydroxide gel was added as an adjuvant. The vaccine was evaluated in rabbits by challenge protection assay and humoral immune response. The mortality rates in control and vaccinated groups were 80% and 10% at day 7 post challenge and 100% and 20% at day 15 post challenge, respectively. Serum antibody titer [GMT] was significantly higher [294.0] in vaccinated group as compared to control group of rabbits [2.63] at day 45. The results showed that the ...

Data presented at ICAAC showed the GEN-004 study met safety, tolerability and immunogenicity goals, including increases in the blood of T helper 17 (TH17) cells, a rare cell type that provides immunity at epithelial and mucosal surfaces. By generating a TH17 T cell-mediated immune response, immunization with GEN-004 may prevent or reduce pneumococcus colonization in the nasopharynx, a precursor to infection caused by all serotypes of pneumoccocus.. The Phase 1 study was a randomized, double-blind, dose-escalation, placebo-controlled clinical trial that enrolled 90 healthy adult volunteers. The primary objective was to evaluate safety and tolerability of GEN-004, which is comprised of three protein antigens, SP0148, SP2108 and SP1912, when administered with and without aluminum hydroxide as an adjuvant. Subjects were randomized to receive 10, 30 or 100µg of each protein/dose with or without 350µg aluminum hydroxide, or placebo, and received three doses, each four weeks apart. GEN-004 was ...
Within this observer-blind study (NCT00423046) ladies (N = 1 106 stratified by age (18-26 27 36 y) were randomized (1:1) to get the HPV-16/18 vaccine (R595 strain. improved antibody and storage B-cell replies when HPV-16/18 L1 VLP vaccine was developed with AS04 weighed against aluminum hydroxide by itself.6 The HPV-6/11/16/18 vaccine includes a proprietary AAHS adjuvant. When developed with HPV-16 vaccine AAHS provides demonstrated greater natural convenience of adsorption of HPV-16 L1 VLPs and better anti-HPV-16 L1 VLP antibody replies compared with lightweight aluminum hydroxide.8 However no research has directly compared the comparative efforts of AS04 and AAHS (using identically portrayed antigens) to vaccine-induced anti-HPV-16/18 defense responses. Talents of our research include the usage of a PBNA which methods a variety of neutralizing antibodies and similar methodology for evaluation of both vaccine groupings.

Abstract. The main target of this work is to prepare refractory magnesia- and aluminabased ceramics within the MgO-Al2O3-ZrO2-SiO2 system. These include periclase (MgO) and its composites with MgAl2O4-spinel and forsterite (MgSiO4)-zirconia (ZrO2) as well as corundum (α-Al2O3) and its composite with mullite (Al6Si2O13)- zirconia (ZrO2). These were processed from recycled pure and fine magnesium and aluminium hydroxide precipitates as well as raw zircon, ilmenite and rutile raw materials. Up to 5.0% lmenite and rutile as well as Mg(OH)2 , Al(OH)3 or MgO were used as doping materials to accelerate sintering rate of the periclase and corundum products. Also 5-20% of calcined alumina and raw zircon were mixed with the magnesium as well as aluminium hydroxides to prepare varieties of periclase-spinel, periclase-forsterite-zirconia as well as corundum-mullitezirconia composites, respectively. The corresponding batches were prepared, semi-dry pressed and fired at two-stages up to 1600 °C. The ...
