Establishment of experimental autoimmune prostatitis model by T2 peptide in aluminium hydroxide adjuvant.

Abstract: A mouse model was developed to simulate the clinical features of chronic prostatitis/chronic pelvic pain syndrome using peptide (T2 ). Forty C57BL/6 mice were divided into four groups of 10 mice each, averagely and randomly. T2 plus aluminium hydroxide adjuvant group was given subcutaneous injection with the emulsion mixture of T2 and aluminium hydroxide adjuvant, the T2 group with T2 , the aluminium hydroxide adjuvant group with aluminium hydroxide adjuvant and the normal control group with 0.9/% NaCl solution. Haematoxylin andeosin staining was used to observe the inflammation of the prostate. Plasma levels of TNF-α and CRP were detected by ELISA kit. The expression of IL-1βin the prostate was investigated by immunohistochemistry. The statistical differences between the groups were compared by t test. Histopathological analyses demonstrated that prostate lesions were most severe in the group immunised with T2 plus aluminium hydroxide adjuvant. Plasma levels of TNF-α and CRP were statistically elevated compared with control groups. The expression levels of IL-1β in the prostate were more obvious than control groups. T2 in aluminium hydroxide adjuvant subcutaneous injection could successfully set up experimental autoimmune prostatitis in C57BL/6 mice. This murine model would be greatly beneficial to further comprehend the aetiology, pathogenesis and explicit treatment of CP/CPPS.

Synthesis of transparent dispersions of aluminium hydroxide nanoparticles.

Abstract: Transparent dispersions of inorganic nanoparticles are attractive materials in many fields. However, a facile method for preparing such dispersions of aluminium hydroxide nanoparticles is yet to be realized. Here, we report a direct reactive method to prepare transparent dispersions of pseudo-boehmite nanoparticles (1 wt%) without any surface modification, and with an average particle size of 80 nm in length and 10 nm in width, as well as excellent optical transparency over 94% in the visible range. Furthermore, transparent dispersions of boehmite nanoparticles (1.5 wt%) were also achieved after an additional hydrothermal treatment. However, the optical transparency of dispersions decreased with the rise of hydrothermal temperature and the shape of particles changed from rhombs to hexagons. In particular, monodisperse hexagonal boehmite nanoplates with an average lateral size of 58 nm and a thickness of 12.5 nm were obtained at a hydrothermal temperature of 220 °C. The selectivity of crystal growth direction was speculated as the possible formation mechanism of these as-prepared aluminium hydroxide nanoparticles. Besides, two values of 19.6 wt% and 14.64 wt% were separately measured for the weight loss of pseudo-boehmite and boehmite nanoparticles after a continuous heating, indicating their potential flame-resistant applications in the fabrication of plastic electronics and optical devices with high transparency.

Content of Aluminium Hydroxide in Lime-Silica Composite and its Influence on Tobermorite Formation

Abstract: Aerated concrete is lightweight building material with excellent thermos-technical properties compared to its strengths, easy workability and economic efficiency. It is material with long tradition of manufacturing since 1924 but its potential is yet possible to be extended. Since the beginning pure ingredients such as lime and silica sand has been used. Nowadays we are looking for ways to replace these expensive raw materials with cheaper alternatives. One of the most important mechanical properties of each material is its strength. In case of aerated concrete the bearer of strength is mineral tobermorite. It is created by reaction of silicon oxides and lime at hydrothermal conditions. It belongs to the group of calcium hydrosilicates with chemical formula Ca5Si6O16(OH)2·4H2O. Main goal of this paper is proposal for modification of the raw materials composition and autoclave regime of aerated concrete using aluminium hydroxide in order to improve final mechanical properties and mineralogical composition.

Abstract: This article reports the synthesis process of γ-alumina/SiO2 composite from aluminium powders and amorphous nanosilica through the means of tetra-methyl-ammonium hydroxide (TMAH) as the mixing medium which produced aluminium hydroxide Al(OH)3 in the form of white powders. The crystal structures, microstructures, and mapping of the atomic constituent of γ-Al2O3 and γ-Al2O3/SiO2 samples were respectively analyzed via X-ray diffraction (XRD), and scanning electron microscopy-energy dispersive X-ray SEM-EDX. At the calcination temperature to 300 °C, the samples still had boehmite phase, and the boehmite phase transformation to γ-alumina phase occurred at temperature of 700-900 °C. The γ-alumina phase began to form at the calcination temperature of 500-700 °C with the crystal structure of (440), (511), (400), (222), (311), and (111). The similar diffraction pattern was also shown by the γ-Al2O3/SiO2 composite for the calcination temperature of 700 °C and 900 °C. The microstructure analysis of the γ-Al2O3/SiO2 showed that SiO2 particles were smaller and round while the γ-Al2O3 particles were bigger and elongated. Additionally, the mapping results showed SiO2 and γ-Al2O3 particles were homogenously distributed.

Feline vaccine-associated sarcomagenesis: Is there an inflammation-independent role for aluminium?

Abstract: Aluminium has been found in feline vaccine-associated sarcomas. In this study, we investigated the potential for aluminium to contribute directly to tumourigenesis. Our results indicated that an aluminium hydroxide adjuvant preparation was cytotoxic and mutagenic in human-Chinese hamster ovary (CHO) hybrid cells in vitro. Moreover, CHO cells deficient in DNA double strand break (DSB), but not single-strand break (SSB), repair, were particularly sensitive to aluminium exposure compared with repair proficient cells, suggesting that aluminium is associated with DSBs. In contrast to CHO cells, primary feline skin fibroblasts were resistant to the cytotoxic effects of aluminium compounds and exposure to an aluminium chloride salt promoted cell growth and cell cycle progression at concentrations much less than those measured in particular feline rabies vaccines. These findings suggest that aluminium exposure may contribute, theoretically, to both initiation and promotion of tumours in the absence of an inflammatory response.
