A multi-tool analytical practice was used for the characterisation of a 16th century carpet manufactured in Cairo. A mild extraction method with hydrofluoric acid has been evaluated in order to isolate intact flavonoids and their glycosides, anthraquinones, tannins, and indigoids from fibre samples. High-performance liquid chromatography coupled to spectroscopic and mass spectrometric detectors was used for the identification of possible marker compounds with special attention paid to natural dyes present in the historical samples...

Alzheimer's disease (AD) is the most common form of dementia and mainly affects cognitive function of the aged populations. Aluminium, a neurotoxic metal, has been suggested as a contributing factor of AD. Caesalpinia crista is a medicinal plant known for its anti-microbial, anti-inflammatory and anti-oxidant properties. The present study was conducted in order to evaluate the neuroprotective effects of methanolic extracts of C. crista (MECC) on aluminium-induced neurodegeneration in rats. Co-administration with MECC significantly and dose dependently ameliorated the aluminium-dependent cognitive impairment, AChE hyperactivity and oxidative stress in the hippocampus and in the frontal cortex of rat brain...

Although xyloglucan (XyG) is reported to bind Aluminium (Al), the influence of XyG fucosylation on the cell wall Al binding capacity and plant Al stress responses is unclear. We show that Arabidopsis T-DNA insertion mutants with reduced AXY3 (XYLOSIDASE1) function and consequent reduced levels of fucosylated XyG are more sensitive to Al than wild-type Col-0 (WT). In contrast, T-DNA insertion mutants with reduced AXY8 (FUC95A) function and consequent increased levels of fucosylated XyG are more Al resistant...

Aluminium (Al) toxicity is the main abiotic stress limiting plant productivity in acidic soils that are widely distributed among arable lands. Plant species differ in the level of Al resistance showing intraspecific and interspecific variation in many crop species. However, the origin of Al-tolerance is not well known. Three annual species, difficult to distinguish phenotypically and that were until recently misinterpreted as a single complex species under Brachypodium distachyon, have been recently separated into three distinct species: the diploids B...

Background and Aims: The non-specific phospholipase C (NPC) is a new member of the plant phospholipase family that reacts to abiotic environmental stresses, such as phosphate deficiency, high salinity, heat and aluminium toxicity, and is involved in root development, silicon distribution and brassinolide signalling. Six NPC genes (NPC1-NPC6) are found in the Arabidopsis genome. The NPC2 isoform has not been experimentally characterized so far. Methods: The Arabidopsis NPC2 isoform was cloned and heterologously expressed in Escherichia coli...

BACKGROUND: Triterpene glycosides are a vast group of secondary metabolites widely distributed in plants including a high number of biologically active compounds. The pharmacological potential is evaluated by using many bioassays particularly in the field of cancerology, immunology, and microbiology. The adjuvant concept is well known for these molecules in vaccines, but there is little preclinical evidence to support this concept in the management of cancer, infections and inflammation...

Chemical precipitation in wastewater stabilization ponds - in Scandinavia called fellings dams - has been in operation for more than 50 years. Slaked lime and aluminium salts are the most common chemicals used for precipitation. Long and narrow forms of the ponds and a detention time of at least 5 days have shown, even at a low water temperature and below an ice cover, to produce an average effluent quality of 70 mg CODCr/l, 0.2 mg Tot-P/l, 20 mg Tot-N/l (CODCr: chemical oxygen demand; Tot-P: total phosphorus; Tot-N: total nitrogen) and low levels of pathogenic bacteria...

Ilex paraguariensis, yerba mate is a native plant from the southern region of Brazil. Studies showed that yerba mate has an antioxidant potential, which could help to reduce the risk of developing neurodegenerative diseases, as Alzheimer's Disease (AD). It's known that I. paraguariensis grows in acid soils with aluminium (Al), which is bioavailable in these soils. Al has a neurotoxic potential related with the progression of neurological disorders. This study aim was to evaluate the potential of I. paraguariensis in the etiology of AD using strains of Caenorhabditis elegans and the concentration of Al and antioxidants in the yerba mate extract...

In recent years, considerable attention has been given to plant colorants for use in dyeing applications because of their newly discovered properties such as insect repellency, deodorizing, antioxidant, sun protection, and antibacterial activity. In view of their better biocompatibility, biodegradability, less-toxicity, natural colorants are gaining worldwide interest for producing elegant hues and highly functional value-added textiles. In the present work, we investigated the coloring and functional finishing of wool with Tectona grandis L leaves extract with the emphasis on effect of metallic salt mordants on colorimetric potential, fastness, radical scavenging potential, and antibacterial activity in an attempt to develop bioactive fibres for use in health care applications...

Aluminium-activated malate transporters (ALMT) form a family of anions channels in plants but little is known about most of its members. This study examined the function of OsALMT4 from rice (Oryza sativa L.). We show that OsALMT4 is expressed in roots and shoots and the OsALMT4 protein localizes to the plasma membrane. Transgenic rice lines over-expressing (OX) OsALMT4 released malate from the roots constitutively and had two-fold higher malate concentrations in the xylem sap than nulls indicating greater concentrations of malate in the apoplast...

Malic acid, one of the major organic acid exudates from roots, plays a significant role in the chemotaxis of beneficial bacteria to the plant's rhizosphere. In this study, the effect of a plant growth promoting rhizobacterium, Bacillus subtilis RR4, on the synthesis and exudation of malic acid (MA) from roots is demonstrated in rice. To test the chemotactic ability of RR4 towards MA, capillary chemotaxis assay was performed which revealed a positive response (relative chemotactic ratio of 6.15 with 10 µM MA) and with increasing concentrations of MA, an elevated chemotactic response was observed...

Christopher E Doughty
Can the presence of herbivores increase global nutrient availability? Animals disperse vital nutrients through ecosystems, increasing the spatial availability of these nutrients. Large herbivores are especially important for the dispersal of vital nutrients due to their long food passage times and day ranges, and large herbivores from past periods (the Pleistocene) may have increased nutrient concentrations on the continental scale. However, such results have been demonstrated theoretically but not yet empirically...

This is the first study to systematically investigate the microbial community structure in cyanobacteria-laden drinking water sludge generated by different types of coagulants (including AlCl3, FeCl3, and polymeric aluminum ferric chloride (PAFC)) using Illumina 16S rRNA gene MiSeq sequencing. Results show that Cyanobacteria, Proteobacteria, Firmicutes, Bacteroidetes, Verrucomicrobia, and Planctomycetes were the most dominant phyla in sludge, and because of the toxicity of high Al and Fe level in AlCl3 and FeCl3 sludges, respectively, the PAFC sludge exhibited greater microbial richness than that in AlCl3 and FeCl3 sludges...

The present study is aimed at improving the aluminium tolerance in maize crop employing the potential of microbial inoculants in conferring resistance to these toxicities via production of certain chelating compounds like siderophores, exopolysachharides and organic acids. Acid soils have now-a-days become one of the key factors for limiting growth of many agriculturally important crops. Aluminium  is one of the major elements present in acid soils and is mainly responsible for toxicity in the soil. This aluminium is rapidly soluble in soil water and hence absorbed by plant roots under conditions where soil pH is below 5...

Cornelia Eisenach, Ulrike Baetz, Nicola V Huck, Jingbo Zhang, Alexis De Angeli, Gerold Beckers, Enrico Martinoia
Stomatal pores are formed between a pair of guard cells, and allow plant uptake of CO2 and water evaporation. Their aperture depends on changes in osmolyte concentration of guard cell vacuoles, specifically of K+ and Mal2-. Efflux of Mal2- from the vacuole is required for stomatal closure; however, it is not clear how the anion is released. Here we report the identification of ALMT4 (ALUMINIUM ACTIVATED MALATE TRANSPORTER 4) as an Arabidopsis thaliana ion channel that can mediate Mal2- release from the vacuole and is required for stomatal closure in response to abscisic acid (ABA)...

Aluminium (Al) is one of the major stressors for plants in acidic soils, negatively affecting plant growth and nutrient balances. Significant efforts have been undertaken to understand mechanisms of Al tolerance in plants. However, little is known of the relevance of iron (Fe) and silicon (Si) nutrition under Al stress conditions. The objectives of this study were to determine whether effects induced by Fe and Si are of importance for limitation of Al moving via xylem in plants (Cucumis sativus L.). Cucumber plants (cv...

This paper focuses on research concerning the ecotoxicological properties of granulated slag from the pilot production of gray iron with red mud addition and concrete composites with the application of this slag. Red mud is a hazardous waste generated in the production of aluminium oxide. Negative ecotoxicological tests are, therefore, one of the basic prerequisites for the ability to use granulated slag from gray iron pilot production. Granulated slag and concrete composite samples with various ratios of granulated slag have been subject to ecotoxicity tests: determining root growth inhibition in the highly-cultivated plant Sinapisalba, and determining acute toxicity in Daphniamagna...

Chlorogenic acid (CGA), a major polyphenolic component of many plants, displays antioxidant and neuroprotective properties in neurodegenerative diseases. To investigate whether CGA may influence aluminium (Al) induced cytotoxicity, aluminium chloride (50 μM Al) was administered in primary hippocampal neuronal cells presupplemented with CGA (10, 50 and 100 μM). Our study shows that the exposure to Al caused cell death, Al(3+) accumulation, reactive oxygen species generation and mitochondrial damage in cells...
