Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.
A by-product of the destructive distillation of coal used as a topical antieczematic. It is an antipruritic and keratoplastic agent used also in the treatment of psoriasis and other skin conditions.

A simple hydroponic culture method for the development of a highly viable root system in Arabidopsis thaliana. (1/1170)In the studies of nutritional absorption and metal toxicity in the root, it is important to grow plants without technical damage. We established a simple hydroponic culture system for Arabidopsis thaliana to obtain a healthy plant having a well-developed root system with many lateral roots. The phytotoxic effects of Cr, Cu, and Al ions were examined by FDA-PI staining using this culture system. The pattern of root inhibition varied with the ion, suggesting the usefulness of this culture system. (+info)
Binding of the transition state analog MgADP-fluoroaluminate to F1-ATPase. (2/1170)Escherichia coli F1-ATPase from mutant betaY331W was potently inhibited by fluoroaluminate plus MgADP but not by MgADP alone. beta-Trp-331 fluorescence was used to measure MgADP binding to catalytic sites. Fluoroaluminate induced a very large increase in MgADP binding affinity at catalytic site one, a smaller increase at site two, and no effect at site three. Mutation of either of the critical catalytic site residues beta-Lys-155 or beta-Glu-181 to Gln abolished the effects of fluoroaluminate on MgADP binding. The results indicate that the MgADP-fluoroaluminate complex is a transition state analog and independently demonstrate that residues beta-Lys-155 and (particularly) beta-Glu-181 are important for generation and stabilization of the catalytic transition state. Dicyclohexylcarbodiimide-inhibited enzyme, with 1% residual steady-state ATPase, showed normal transition state formation as judged by fluoroaluminate-induced MgADP binding affinity changes, consistent with a proposed mechanism by which dicyclohexylcarbodiimide prevents a conformational interaction between catalytic sites but does not affect the catalytic step per se. The fluorescence technique should prove valuable for future transition state studies of F1-ATPase. (+info)
Fluorimetric determination of aluminum traces in hemodialysis solutions using Mordant Red 19. (3/1170)A sensitive and accurate method for the spectrofluorimetric determination of trace levels of aluminum in hemodialysis solutions using Mordant Red 19 as the complexation reagent has been developed. The optimal experimental conditions for the concentration of fluorimetric reagent, pH, temperature, and the specific type of matrix are reported. The emission of the fluorescent metal chelate was measured at 555 nm, excitation at 478 nm. Linearity between emission intensity and aluminum concentration was found in the 2-20 ppb range in standard aluminum solutions. Limit of detection was 0.4 ppb. The aluminum amounts in some commercial hemodialysis solutions were determined by means of the extrapolation method. The proposed method proved to be suitable in terms of sensitivity and accuracy for the determination of aluminum in dialysis fluids. (+info)
Aluminum is a weak agonist for the calcium-sensing receptor. (4/1170)BACKGROUND: Aluminum (Al3+) has diverse biological effects mediated through activation of a putative extracellular cation-sensing receptor. A recently identified calcium-sensing receptor (CaSR), which has been identified in target tissues for Al3+, may transduce some of the biological effects of Al3+. METHODS: To test this possibility, we transfected human embryonic kidney 293 (HEK 293) cells with a cDNA encoding the rat CaSR and evaluated CaSR expression by Western blot analysis and function by measurement of intracellular calcium ([Ca2+]i) levels and inositol monophosphate (IP1) generation following stimulation with Al3+ and a panel of CaSR agonists. RESULTS: The CaSR protein was detected by immunoblot analysis in cells transfected with the CaSR cDNA but not in nontransfected HEK 293 cells. In addition, [Ca2+]i levels and IP1 generation were enhanced in a dose-dependent fashion by additions of the CaSR agonists calcium (Ca2+), magnesium (Mg2+), gadolinium (Gd3+), and neomycin only in cells transfected with CaSR. To determine if Al3+ activated CaSR, we stimulated cells transfected with rat CaSR with 10 microM to 1 mM concentrations of Al3+. Concentrations of Al3+ in the range of 10 microM to 100 microM had no effect on [Ca2+]i levels or IP1 generation. In contrast, 1 mM Al3+ induced small but significant increases in both parameters. Whereas Gd3+ antagonized calcium-mediated activation of CaSR, pretreatment with Al3+ failed to block subsequent activation of rat CaSR by Ca2+, suggesting a distinct mechanism of Al3+ action. CONCLUSION: Al3+ is not a potent agonist for CaSR. Because Al3+ affects a variety of target tissues at micromolar concentrations, it seems unlikely that CaSR mediates these cellular actions of Al3+.

High-resolution PET imaging for in vivo monitoring of tumor response after photodynamic therapy in mice. (5/1170)The aim of this study was to investigate the use of [18F]fluoro-2-deoxy-D-glucose (FDG) and a small-animal PET scanner to assess early tumor response after photodynamic therapy (PDT) in mice. PDT consists of intravenous administration of a photosensitizer that accumulates preferentially in tumor tissue, followed by local illumination of the tumor with red light. Two different photosensitizers were used: Photofrin (PII), which has been approved for clinical use, and disulfonated aluminum phthalocyanine (AIPcS), which is a second-generation drug. These drugs have been shown to induce tumor necrosis through different action mechanisms, i.e., mainly initial vascular stasis (PII) or direct tumor cell kill (AIPcS). FDG PET was used to follow both perfusion and metabolic activity in the tumor tissue. METHODS: The study was performed using a mouse model implanted with two contralateral murine mammary tumors (5 mm diameter x 2.5 mm thickness) on the back. Only one tumor was subjected to PDT, whereas the other tumor served as a control. A total of 13 mice were studied, 1 without illumination, 3 at 30 min and 3 at 2 h after PDT with both PII-PDT and AIPcS-PDT. Dynamic PET imaging of the mice, which were placed in pairs in a prostate position parallel to the transaxial planes of the Sherbrooke animal PET scanner, was performed after a bolus injection of 11 MBq (300 microCi) FDG. Blood samples were collected concurrently from 1 mouse during each study using an automated microvolumetric blood sampler. RESULTS: Analysis of the tumor time-activity curves showed that (a) scans during the first 3 min provided an estimate of tumor perfusion, as confirmed by the blood samples; (b) the tumor FDG uptake after 15 min was a direct measurement of tumor metabolism clearly demonstrating the relative efficacy of the two PDT drugs; and (c) the tumor tracer concentration in the interval 3-15 min after FDG injection is an appropriate indicator of the different mechanisms of tumor necrosis through indirect vascular stasis (PII) or direct cell kill (AIPcS). CONCLUSION: This pilot study confirmed the feasibility of using dynamic in vivo PET imaging for assessing early tumor response to PDT in mice. (+info)
Evidence that cytosolic phospholipase A2 is down-regulated by protein kinase C in intact human platelets stimulated with fluoroaluminate. (6/1170)We reported that protein kinase C (PKC) inhibitors increase the release of arachidonic acid induced by fluoroaluminate (AlF4-), an unspecific G-protein activator, in intact human platelets. Now we demonstrate that this effect is independent of the extracellular Ca2+ concentration and that AlF4(-)-induced release of AA is abolished by BAPTA, an intracellular Ca2+ chelator, even in the presence of GF 109203X, a specific and potent PKC inhibitor. This compound also blocks the liberation of the secretory phospholipase A2 in the extracellular medium, indicating that this enzyme is not involved in the potentiation of arachidonic acid by PKC inhibitors. On the other hand, the latter effect is completely abolished by treatment of platelets with AACOCF3, a specific inhibitor of cytosolic phospholipase A2 (cPLA2). These observations indicate that cPLA2 is responsible for the AlF4(-)-induced release of arachidonic acid by a mechanism that is down-regulated by PKC. (+info)
A preliminary study of dietary aluminium intake and risk of Alzheimer's disease. (7/1170)BACKGROUND: epidemiological studies of Alzheimer's disease and aluminium intake have focused on aluminium in drinking water. There have been no studies investigating the relation between the disease and the consumption of foods containing large amounts of aluminium additives. OBJECTIVES: to conduct a pilot study to determine whether dietary intake of aluminium additives differs in individuals with and without Alzheimer's disease. DESIGN: matched case-control study. Controls were matched to cases on age, gender and date of admission to the centre. SETTING: Syracuse, New York, USA. SUBJECTS: 46 participants comprising 23 matched sets. METHODS: residents of the Loretto Geriatric Center with and without newly-diagnosed Alzheimer's disease were selected. Next-of-kin were asked to complete information on the resident's medical history, lifestyle behaviour and dietary intake before admission to the centre. An expanded form of the Health Habits and History Questionnaire was used to determine dietary intake. Consumption of foods containing elevated levels of aluminium additives was compared between cases and controls. RESULTS: the crude odds ratio for daily intake of foods containing high levels of aluminium was 2.0 and, when adjusted for covariates, was 8.6 (P=0.19). Intake of pancakes, waffles, biscuits, muffins, cornbread and/or corn tortillas differed significantly (P=0.025) between cases and controls. Adjusted odds ratios were also elevated for grain product desserts, American cheese, chocolate pudding or beverages, salt and chewing gum. However, the odds ratio was not elevated for tea consumption. CONCLUSION: past consumption of foods containing large amounts of aluminium additives differed between people with Alzheimer's disease and controls, suggesting that dietary intake of aluminium may affect the risk of developing this disease. Larger studies are warranted to corroborate or refute these preliminary findings. (+info)
Effects of aluminum potassium sulfate on learning, memory, and cholinergic system in mice. (8/1170)AIM: To study the relationship between aluminum potassium sulfate (APS) and memory deficits of mice. METHODS: 30, 60, or 90 d after the mice were given daily APS i.g., the step-through latency (STL) was determined with a passive avoidance task. Aluminum (Al) contents in brain and blood were assayed with atomic absorption spectrophotometry. Acetylcholine (ACh) content in brain was determined with chemiluminescent method and choline acetyltransferase (ChAT) activity was measured radiochemically. RESULTS: APS 1 g.kg-1 increased blood-Al only after 30 d. After 60 d, STL, ACh content and ChAT activity decreased by 46.4%, 8.5%, and 22.6%, respectively. These parameters decreased by 50%, 11.1%, and 27.8%, respectively, with increased Al in blood and brain, after 90 d. APS 0.25 g.kg-1 had no effects on mice except blood-Al. In ethylcholine mustard aziridium chloride (AF64A) treated mice, APS 1 g.kg-1 only increased blood and brain-Al. CONCLUSION: The intake of APS 1 g.kg-1.d-1 for 60 d induced learning and memory deficits in mice. (+info)

All patients had always been treated with a dialysate containing negligible amounts of aluminum. The serum aluminum levels of hemodialysis and CAPD patients were not significantly different, not related to age or sex, and not affected by the presence of diabetes or vitamin D intake. The most important determinant of serum aluminum level in the hemodialysis patients was the current dose of aluminum-containing phosphate-binding medication. This relationship was most striking in the compliant patients. In hemodialysis patients, after an increase during the first one to two ...

The behavior has been evaluated by potentiodynamic polarization measurements. The results show the Fe-Al alloys, which the Al content of alloy exceeds 19 at %, have wide passivation regions with low passivation current. However, when the Al content of Fe-Al alloys exceeds this range, the increment of Al content has slight influence on passivation behavior compared with ternary Cr addition..

Vaccine ingredients quotes
This is especially surprising because of the limitations of the Cochrane Collaborations study. They looked at the effects of only one standard aluminum-containing vaccine, rather than the effects of all four being administered at once. They didnt study aluminum metabolism itself. They didnt test aluminum levels in children after vaccination, nor did they explore whether or not the amount of aluminum in vaccines builds up in the brain or bone tissues. They looked only for evidence of external symptoms of aluminum toxicity, not internal effects. Nor did they do their own research; instead, they reviewed all available studies conducted by other investigators. Despite all this, the Cochrane Collaboration study essentially closed the book on investigating aluminum toxicity from vaccines, without really having opened it in the first place.

Increased nitric oxide in exhaled air: an early marker of asthma in non-smoking aluminium potroom workers? | Occupational &...
The main finding of this study was that exhaled NO concentrations in non-smoking potroom workers were 63% higher than in non-smoking control subjects recruited from the same plant. The two groups were otherwise comparable for occurrence of asthma-like symptoms and use of β2-agonists. No subject in either group used corticosteroids. The potroom workers were somewhat younger than the controls (mean age 40 v 46 years), but concentrations of exhaled NO have not been shown to vary with age.12 Although the exhaled NO concentration in the non-smoking potroom workers was not as high as that found in symptomatic asthmatic subjects, it was comparable to the concentration observed in atopic subjects with bronchial hyperresponsiveness.18 In smokers, we found no difference in exhaled NO between potroom workers and controls. This may be because chronic cigarette smoking itself decreases exhaled NO, both in healthy19 and in asthmatic subjects.20 In mildly asthmatic subjects, the effect of smoking on exhaled ...

Increasing the plant Al-detoxification capacity and/or breeding Al-resistant cultivars are a cost-effective strategy to support crop growth on acidic soils. The plasma membrane H+-ATPase plays a central role in all plant physiological processes. Changes in the activity of the plasma membrane H+-ATPase through regulating the expression and phosphorylation of this enzyme are also involved in many plant responses to Al toxicity.

The occurrence of work-related asthma has been shown to be associated with the duration of potroom employment, although the prevalence of asthmatic symptoms is not significantly different from that of the general population. Typical manifestations of occupational asthma are described in potroom workers, and a close relationship between the levels of fluoride exposure and work-related asthmatic symptoms has been observed. The existence of occupational asthma in aluminium potroom workers has been confirmed by characteristic patterns of repeated peak flow measurements, supported by changes in methacholine responsiveness in workers with suspected work-related asthma. However, no immunological test is available to establish the diagnosis. Methacholine challenge appears to be inappropriate for screening aluminium potroom workers in order to detect work-related asthma. Current ...
Maize ZmALMT2 is a root anion transporter that mediates constitutive root malate efflux - GOV.UK
Root efflux of organic acid anions underlies a major mechanism of plant aluminium (Al) tolerance on acid soils. This efflux is mediated by transporters of the Al-activated malate transporter (ALMT) or the multi-drug and toxin extrusion (MATE) families. ZmALMT2 was previously suggested to be involved in Al tolerance based on joint association-linkage mapping for maize Al tolerance. In the current study, we functionally characterized ZmALMT2 by heterologously expressing it in Xenopus laevis oocytes and transgenic Arabidopsis. In oocytes, ZmALMT2 mediated an Al-independent electrogenic transport product of organic and inorganic anion efflux. Ectopic overexpression of ZmALMT2 in an Al-hypersensitive Arabidopsis KO/KD line lacking the Al tolerance genes, AtALMT1 and AtMATE, resulted in Al-independent constitutive root malate efflux which partially restored the Al tolerance phenotype. The lack of correlation between ZmALMT2 expression and Al tolerance (e.g., expression not localized to the root tip, ...
Molecular regulation of aluminum resistance and sulfur nutrition during root growth
Main conclusion: Aluminum toxicity and sulfate deprivation both regulate microRNA395 expression, repressing its low-affinity sulfate transporter (SULTR2;1) target. Sulfate deprivation also induces the high-affinity sulfate transporter gene (SULTR12), allowing enhanced sulfate uptake. Few studies about the relationships between sulfate, a plant nutrient, and aluminum, a toxic ion, are available; hence, the molecular and physiological processes underpinning this interaction are poorly understood. The Al-sulfate interaction occurs in acidic soils, whereby relatively high concentrations of trivalent toxic aluminum (Al3+) may hamper root growth, limiting uptake of nutrients, including sulfur (S). On the other side, Al3+ may be detoxified by complexation with sulfate in the acid soil solution as well as in the root-cell vacuoles. In this review, we focus on recent insights into the mechanisms governing plant responses to Al toxicity and its relationship with sulfur nutrition, emphasizing the role of ...

Aluminum Induces Oxidative Stress Genes in Arabidopsis thaliana | Plant Physiology
A simple conclusion that can be drawn from these similarities might be that Al stress corresponds to a form of oxidative stress. One of the suggested mechanisms of Al toxicity is that it causes lipid peroxidation (Gutteridge et al., 1985; Kochian, 1995). In vivo studies have shown that Al treatment increases the activation of several oxidative stress enzyme activities (Cakmak and Horst, 1991). Moreover, Al3+ exacerbates oxidative stress induced by Fe2+ (Ono et al., 1995) and the antioxidantN,N′diphenyl-p-phenylenediamine protected against Al toxicity (Yamamoto et al., 1996). However, the interaction between Fe2+ and Al3+ does not occur in all medium conditions (for discussion, see Yamamoto et al., 1996), and no lipid peroxidation was found in Al-treated soybean cultures (Stass and Horst, 1995). An alternative mechanism for Al toxicity was suggested recently that may also involve oxidative stress. Lukazewski and Blevins (1996) showed that Al treatment impairs ascorbate metabolism, perhaps by ...
Debunked: What In The World Are They Spraying? - Contrail Science
Subject: A few brief point on What in the world. Dear Sir,. I watched your documentary, What in the world are they spraying with interest, but I have a few of issues Id like to raise.. 1) The film seems to suggest that water from the pond was tested at 375,000 ug/L aluminum. However the lab report says it was sediment. Since sludge is basically soil, then 375,000 ug/L is a perfectly normal level. Ordinary soil has an aluminum content averaging 7.1%, or 71,000,000 ug/L. 2) The hair test on the little girl were used to suggest that aluminum must have been sprayed. Yet the levels on the report were only 33% higher than that listed for a healthy adult, and children are known to naturally excrete aluminum at a higher rate than adults. Hence the use of that test result seems rather misleading.. 3) Aluminum toxicity in soil has been a known problem for a hundred years. Breeding crops to be aluminum resistent has always been a goal, and hence a normal application of genetic modification. How then ...
Effect of the Concentration of Aluminum on the Adsorption, Texture, and Structure Characteristics of a Mesoporous Mineral...
Abstract: The effect of Al ion implantation on the properties of mesoporous aluminosilicate mineral phases of the SBA-15 type was studied. The implantation of Al was performed immediately under conditions of the synthesis of SBA-15 in a weakly acidic medium (pH ∼ 2.9). It was found that, under these conditions, the amount of Al that can be implanted into the SBA-15 framework is limited (a maximum of 7.2 mol %). According to XPS data, aluminum ions were implanted into the matrix of silica rather than occurring on the surface as an individual phase. The study of nitrogen adsorption at 77 K and the results obtained by X-ray diffractometry and high-resolution electron microscopy suggest that Al-SBA-15 materials exhibited a hexagonal structure of channel pores of the same diameter of 8.3 nm, and the unit cell parameter was 12.3 nm. The degree of crystallinity of the material increased with the concentration of Al ...
Silicon, aluminium and the biological availability of phosphorus in algae | Proceedings of the Royal Society of London B:...
Silicon is an essential element for growth in diatoms. It is, for example, used to build the silicieous frustule surrounding the diatom cell wall. Silicon starvation studies have also inferred that silicon is essential in the vital metabolic processes of DNA and chlorophyll synthesis. The mechanism of essentiality is, however, uncertain. In laboratory cultures at circumneutral pH and using a non-growth-limiting, but environmentally realistic, concentration of the essential nutrient phosphorus, we have demonstrated aluminium toxicity in the freshwater diatom Navicula pelliculosa and the amelioration of this toxicity with silicon, present in aqueous solution as silicic acid. The mechanism of aluminium toxicity was an aluminium-induced reduction in the biologically available phosphorus fraction and silicic acid protected against this effect by preferentially binding aluminium in competition with phosphorus. Silicon stimulated growth in the presence of aluminium was also demonstrated in the ...
Newsletters: Labeling of Aluminum Content in HPN - Oley Foundation
In 1997 Bishop et. al. published a study on Aluminum neurotoxicity in preterm infants receiving intravenous-feeding solutions in the New England Journal of Medicine (May 29, 1997;336, 22:1557-61), which showed that premature infants who received standard HPN had lower neurologic development scores than those who received a specially-made aluminum-depleted HPN solution. Based on the Bishop study, the FDA established that up to 4-5 ug/kg/day of aluminum taken parenterally was safe, with no increased amounts found in the patients plasma, urine or tissues. Higher levels may be safe for adults, but further research is necessary and is ongoing. The American Society for Clinical Nutrition (ASCN) and American Society for Parenteral and Enteral Nutrition (ASPEN) state that increased amounts of aluminum found in plasma, urine or tissue without overt signs of toxicity, or exposure to 15 to 30 ug/kg/day parenterally, is unsafe; while bone pain and patchy osteomalacia (shown to be due to aluminum) or ...

NG tube and heartburn - Crohns Disease Forum - Support group and forum for Crohns Disease, Ulcerative Colitis, and other IBD
GENERALLY AVOID: The concomitant administration of aluminum-containing products (e.g., antacids and phosphate binders) and citrates may significantly increase serum aluminum concentrations, resulting in toxicity. Citrates or citric acid are contained in numerous soft drinks, citrus fruits, juices, and effervescent and dispersible drug formulations. Citrates enhance the gastrointestinal absorption of aluminum by an unknown mechanism, which may involve the formation of a soluble aluminum-citrate complex. Various studies have reported that citrate increases aluminum absorption by 4.6- to 50-fold in healthy subjects. Patients with renal insufficiency are particularly at risk of developing hyperaluminemia and encephalopathy. Fatalities have been reported. Patients with renal failure or on hemodialysis may also be at risk from soft drinks and effervescent and dispersible drug formulations that contain citrates or citric acid. It is unknown what effect citrus fruits or juices would have on aluminum ...

Aluminium - Choose Life
By Christopher Exley & Matthew J Mold. Abstract. A burgeoning body of research confirms and affirms the presence of aluminium in human brain tissue. Recently, the first data on aluminium content of brain tissue from donors with diagnoses of familial Alzheimers disease, autism spectrum disorder, multiple sclerosis and epilepsy have been published. Quantitative data are supported by aluminium-specific fluorescence microscopy identifying the locations of aluminium in human brain tissue. The challenge in the future will be to confirm or refute the role played by brain aluminium intoxication in human neurodegenerative disease. Human exposure to aluminium is burgeoning . Living in the aluminium age ensures that the myriad ways in which we are exposed to aluminium today will be even more numerous tomorrow. Aluminium in human brain tissue is the inevitable consequence of this burgeoning exposure . However, what are the consequences of aluminium in human brain tissue? We know that aluminium does ...
IJERPH | Free Full-Text | Aluminium in Brain Tissue in Epilepsy: A Case Report from Camelford
Reviewer 2 Report. Manuscript ID: ijerph-508342. Type of manuscript: Case Report. Title: Aluminium in brain tissue in epilepsy: A case report from Camelford. This Case Report describes several tests performed on different portions of brain tissue of a 60-year-old man who died of asphyxiation brought on by an epileptic fit. This man was part of the population of the Cornish town of Camelford, which in 1988 was subjected to a very high aluminium exposure through drinking water. With the results obtained, the authors intend to prove the role of aluminium in the death of this man.. With this work the authors demonstrated a correlation between several specific microscopy tests performed in different brain areas and the aluminium concentration obtained by Atomic Absorption in the same zones, especially the hippocampus and occipital lobe. The main conclusion I draw from this work, and which is also mentioned by the authors, is the fact that it is important not to forget this incident and to continue ...
Disorganized distribution of homogalacturonan epitopes in cell walls as one possible mechanism for aluminium-induced root...
Background and Aims. Aluminium (Al) toxicity is one of the most severe limitations to crop production in acid soils. Inhibition of root elongation is the primary symptom of Al toxicity. However, the underlying basis of the process is unclear. Considering the multiple physiological and biochemical functions of pectin in plants, possible involvement of homogalacturonan (HG), one of the pectic polysaccharide domains, was examined in connection with root growth inhibition induced by Al.. Methods. An immunolabelling technique with antibodies specific to HG epitopes (JIM5, unesterified residues flanked by methylesterifed residues; JIM7, methyl-esterified residues flanked by unesterified residues) was used to visualize the distribution of different types of HG in cell walls of root apices of two maize cultivars differing in Al resistance.. Key Results. In the absence of Al, the JIM5 epitope was present around the cell wall with higher fluorescence intensity at cell corners lining the intercellular ...
OSA | The partial space qualification of a vertically aligned carbon nanotube coating on aluminium substrates for EO...
The fabrication of NanoTube Black, a Vertically Aligned carbon NanoTube Array (VANTA) on aluminium substrates is reported for the first time. The coating on aluminium was realised using a process that employs top down thermal radiation to assist growth, enabling deposition at temperatures below the substrates melting point. The NanoTube Black coatings were shown to exhibit directional hemispherical reflectance values of typically less than 1% across wavelengths in the 2.5 µm to 15 µm range. VANTA-coated aluminium substrates were subjected to space qualification testing (mass loss, outgassing, shock, vibration and temperature cycling) before their optical properties were re-assessed. Within measurement uncertainty, no changes to hemispherical reflectance were detected, confirming that NanoTube Black coatings on aluminium are good candidates for Earth Observation (EO) applications.. © 2014 Optical Society of America.

Effect of aluminium on urinary acidification in the rat: influence of parathyroid hormone | Clinical Science
1. The influence of thyroparathyroidectomy and/or acidosis on renal function and specifically on acid excretion was studied in rats treated with a cumulative dose of 2 mg of aluminium.. 2. Aluminium-treated and non-treated thyroparathyroidectomized rats showed a significant decrease in glomerular filtration rate and in the urinary/plasma inulin ratio without alteration in net acid excretion.. 3. Non-treated thyroparathyroidectomized acidotic rats showed a significant fall in the amount of ammonium excreted and in overall acid excretion, suggesting that parathyroid hormone participates in an important way in the defence against metabolic acidosis.. 4. The effects of acidosis, thyroparathyroidectomy and aluminium treatment on renal function parameters were not additive, suggesting a common final mechanism. In normal or acidotic aluminium-treated rats, thyroparathyroidectomy had no effect on renal acid excretion, suggesting that aluminium even in low doses inhibited the action of PTH on the renal ...

Реферат: Modification of the oxide surface of aluminium oxide with oxalate complexes of aluminium was carried out, followed by thermal treatment for the purpose of varying the ratio between the functional groups on the surface (ОН groups, Lewis acid centres). It was established that the modification of γ-Al2O3 causes a 1.5-fold increase in the amount of adsorbed platinum (IV) complexes and the fraction of these complexes strongly bound with the surface of the support. The effect of γ-Al2O3 surface modification on the catalytic properties of the system Pt/Al2O3 was demosntrated. It was shown that an increase in the fraction of platinum forms strongly bound with the support causes an increase in the content of methylcyclopentane in the products of n-hexane isomerization and an increase in the selectivity of the formation of propylene in propane transformations ...

Allelic variation analysis and development of gene-specific molecular markers confering acid soil tolerance in barley (Hordeum...
Acid soil is a prevalent problem over the world. The high concentration of Al in the acid soil is one of the major production limiting factors to many plants. Decades of studies have resulted in a significant progress in revealing the mechanism of Al tolerance in plants. Several key genes have been identified and the Al tolerance was validated to be related with gene sequence variations in some plants. Barley (Hordeum vulgare L.) is one of most sensitive cereals to aluminum toxicity. This thesis was aimed at revealing the mechanisms of Al tolerance in barley using the marker development, QTL, association mapping and sequencing techniques. The major findings of the thesis are listed below ...
The inhibition of root growth by aluminum (Al) is well established, yet a unifying mechanism for Al toxicity remains unclear. The association between cell growth and endogenously generated ionic currents measured in many different systems, including plant roots, suggests that these currents may be directing growth. A vibrating voltage microelectrode system was used to measure the net ionic currents at the apex of wheat (Triticum aestivum L.) roots from Al-tolerant and Al-sensitive cultivars. We examined the relationship between these currents and Al-induced inhibition of root growth. In the Al-sensitive cultivar, Scout 66, 10 micromolar Al (pH 4.5) began to inhibit the net current and root elongation within 1 to 3 hours. These changes occurred concurrently in 75% of experiments. A significant correlation was found between current magnitude and the rate of root growth when data were pooled. No changes in either current magnitude or growth rate were observed in similar experiments using the ...
Fluoride Action Network | Study of potential transfer of aluminum to the brain via the olfactory pathway.
Many employees in the aluminum industry are exposed to a range of aluminum compounds by inhalation, and the presence of ultrafine particles in the workplace has become a concern to occupational health professionals. Some metal salts and metal oxides have been shown to enter the brain through the olfactory route, bypassing the blood-brain barrier, but few studies have examined whether aluminum compounds also use this pathway. In this context, we sought to determine whether aluminum was found in rat olfactory bulbs and whether its transfer depended on physicochemical characteristics such as solubility and granulometry. Aluminum salts (chloride and fluoride) and various nanometric aluminum oxides (13nm, 20nm and 40-50nm) were administered to rats by intranasal instillation through one nostril (10?g Al/30?L for 10days). Olfactory bulbs (ipsilateral and contralateral relative to instilled nostril) were harvested and the aluminum content was determined by graphite furnace atomic absorption ...
JOSH LEDERMAN, VIVIAN SALAMA, AP. WASHINGTON (AP) - The Obama administration filed a trade complaint with the World Trade Organization on Thursday against China for allegedly dumping aluminum on the global market at artificially low prices.. U.S. Trade Representative Michael Froman said China is using artificially cheap loans and illegal subsidies to undercut the global price of aluminum. That makes it harder for the U.S. aluminum industry to sell its products overseas at competitive prices.. China gives its aluminum industry an unfair advantage through underpriced loans and other illegal government subsidies, President Barack Obama said in a statement. These kinds of policies have disadvantaged American manufacturers and contributed to the global glut in aluminum, steel and other sectors.. This is the 16th trade enforcement challenge the U.S. has filed against China through the WTO. Its unclear what effect it will have considering the Obama administration ends in just over a ...
Aluminum induces rapidly mitochondria-dependent programmed cell death in Al-sensitive peanut root tips | Botanical Studies |...
Although many studies suggested that aluminum (Al) induced programmed cell death (PCD) in plants, the mechanism of Al-induced PCD and its effects in Al tolerance is limited. This study was to investigate the mechanism and type of Al induced PCD and the relationship between PCD and Al tolerance. In this study, two genotypes of peanut 99-1507 (Al tolerant) and ZH2 (Al sensitive) were used to investigate Al-induced PCD. Peanut root growth inhibition induced by AlCl3 was concentration and time-dependent in two peanut varieties. AlCl3 at 100 μM could induce rapidly peanut root tip PCD involved in DNA cleavage, typical apoptotic chromatin condensation staining with DAPI, apoptosis related gene Hrs203j expression and cytochrome C (Cyt c) release from mitochondria to cytosol. Caspase3-like protease was activated by Al; it was higher in ZH2 than in 99-1507. Al increased the opening of mitochondrial permeability transition pore (MPTP), decreased inner membrane potential (ΔΨm) of mitochondria. Compared with the
Ammonium perchlorate composite propellant - Wikipedia
Though increasing the ratio of metal fuel to oxidizer up to the stoichiometric point increases the combustion temperature, the presence of an increasing molar fraction of metal oxides, particularly aluminum oxide (Al2O3) precipitating from the gaseous solution creates globules of solids or liquids that slow down the flow velocity as the mean molecular mass of the flow increases. In addition, the chemical composition of the gases change, varying the effective heat capacity of the gas. Because of these phenomena, there exists an optimal non-stoichiometric composition for maximizing Isp of roughly 16% by mass, assuming the combustion reaction goes to completion inside the combustion chamber. The combustion time of the aluminum particles in the hot combustion gas varies depending on aluminum particle size and shape. In small APCP motors with high aluminum content, the residence time of the combustion gases does not allow for full combustion of the aluminum and thus a substantial fraction of the ...
