Objective: To discusses the feasibility of establishing the allergic rhinitis (AR) model in Kunming mice. Methods: Kunming mice (n=20) and BALB/c mice (n=20) were sensitized and motivated by ovalbumin (OVA) and aluminium hydroxide. The symptoms rating scale (symptoms score>5 as successful model) was used to evaluate AR symptoms of two kinds of mice after the AR model were set up. The differences of OVA serum specific IgE (OVA-sIgE) and the levels of interleukin 4 (IL-4) in Kunming mice model group and Kunming mice blank group were evaluated, the symptom scores, OVA serum specific IgE (OVA-sIgE) and the levels of interleukin 4 (IL-4) of successful model of Kunming mice and BALB/c mice were compared, and the difference between two kinds of animal models...

Because final properties of nanoscale polymeric structures are largely determined by the solid-state microstructure of the confined polymer, it is imperative not only to understand how the microstructure of polymers develops under nanoscale confinement but also to establish means to manipulate it. Here we present a series of processing strategies, adapted from methods used in bulk polymer processing, that allow to control the solidification of polymer materials confined in the nanopores of anodic aluminium oxide (AAO) templates...

Taking advantage of nanostructured metal films as plasmonic colour filters has been evolved remarkably as an alternative to the conventional technologies of chemical colour filtering. However, most of the proposed plasmonic colour filters depict a poor colour purity focusing on the generating of either the additive or subtractive colours. In this paper, we present dual mode operation plasmonic colour filters employing an opaque aluminium film patterned with sub-wavelength holes. Subtractive colours like cyan, magenta, and yellow are the results of reflection mode of these filters yielding optical efficiencies as high as 70-80 percent and full width at half maximum of the stop-bands up to 40-50 nm...

INTRODUCTION: Literature on the potential release of trace elements following implantation of Zirconia-platelet toughened alumina (ZPTA) ceramic components is scant. The present study therefore analysed the in vitro and in vivo potential release of ions from ZPTA bearings. MATERIAL AND METHODS: An in vitro and in vivo study was conducted. The in vitro study compared leaching in bovine serum from two groups: ZPTA ceramic heads and Co-28Cr-6Mo alloy heads, both 28-mm diameter...

Slope failure has become a major concern in Malaysia due to the rapid development and urbanisation in the country. It poses severe threats to any highway construction industry, residential areas, natural resources and tourism activities. The extent of damages that resulted from this catastrophe can be lessened if a long-term early warning system to predict landslide prone areas is implemented. Thus, this study aims to characterise the relationship between Oxisols properties and soil colour variables to be manipulated as key indicators to forecast shallow slope failure...

Plasmonic resonances in metallic nanoparticles have been used since antiquity to colour glasses. The use of metal nanostructures for surface colourization has attracted considerable interest following recent developments in plasmonics. However, current top-down colourization methods are not ideally suited to large-scale industrial applications. Here we use a bottom-up approach where picosecond laser pulses can produce a full palette of non-iridescent colours on silver, gold, copper and aluminium. We demonstrate the process on silver coins weighing up to 5 kg and bearing large topographic variations (∼1...

Lung cancer, mostly non-small cell lung cancer (NSCLC), is the leading cause of cancer deaths; however, efficient treatments for NSCLC remain insufficient. The objective of this study was to investigate the effects of an epidermal growth factor receptor (EGFR) mutation on autophagic cell death in human lung adenocarcinoma cells by 20-nm zinc oxide nanoparticles (ZnONP20) and aluminum-doped ZnONPs (Al-ZnONP20). Two types of human lung adenocarcinoma cells were used throughout the study: wild-type EGFR A549 cells and EGFR-mutated CL1-5 cells...

An investigation of adsorption of sulphide ion (S(2-)) in water onto carbon/alumina nano-composites synthesized from aluminium carboxylate precursors, in presence of HCl, NaOH, NaCl and surfactant is reported in this paper. A controlled oxygen free pyrolytic technique has been adopted for the synthesis of nano-composites, using acetate, acetyl acetonate, lactate and distearate of aluminium and activated carbon. XRD, SEM and TEM studies of the composites show that they contain clusters made of nano carbon particles of size 50-130nm into which nano alumina particles of size around 10nm are dispersed...

Direct visualization at 1873 K of 0% to 8% molten FeAl droplets suspended in a SiO2 enriched oxide medium was carried out to image the evolution of droplet morphology during reaction between Al and SiO2. Phenomena such as perturbation growth, necking and budding of offspring droplets from a bulk body are observed. The observations are used to discuss and inform a new approach to the nature of interfacial tension and the impact this has on concepts used to define interfacial tension for a two phase system with material exchange across the interface...

The spatial resolution of traditional Magnetic Resonance Imaging (MRI) techniques is typically dictated by the strength of the applied magnetic field gradients, resulting in hard resolution limits of the order of 20-50 μm in favorable circumstances. We demonstrate here a technique which is suitable for the interrogation of regions at specified distances below the surface of conducting objects with a resolution well below these limiting values. This approach does not rely on magnetic field gradients, but rather on the spatial variation of the radiofrequency field within a conductor...

OBJECTIVE: Mucopolysaccharidosis (MPS) IVA (Morquio syndrome A) is an autosomal-recessive lysosomal storage disorder caused by the deficiency of N-acetylgalactosamine-6-sulfatase (GALNS) resulting in excessive lysosomal storage of keratan sulfate. Treatments for MPS IVA have recently become available with optimal outcomes associated with early diagnosis and treatment which can be achieved by newborn screening. DESIGN: Newborn screening programme for MPS IVA pilot study...

Hyperhidrosis affects 4.8% of the U.S. population and has been underestimated by physicians for long time despite considerable interference with quality of life. Many patients suffer from primary (idiopathic) hyperhidrosis which results from over-activity of sympathetic nerves and is restricted to specific body areas, mostly the axillae, palms, soles, or head. Secondary hyperhidrosis is caused by an underlying disease or the intake of medications and often involves large parts of the body. Numerous effective therapies with topical or systemic drugs and surgical options are available...

This study investigated total mercury contents in areas impacted by aluminium plants in Tajikistan and Slovakia and in one area flooded with red mud in Hungary. We present the first determination of total mercury contents in the near-top soil (0-10 and 10-20 cm) in Tajikistan and the first comparative investigation of Tajikistan-Slovakia-Hungary. The Tajik Aluminium Company (TALCO) is one of the leading producers of primary aluminium in Central Asia. In the past 30 years, the plant has been producing large volumes of industrial waste, resulting in negative impacts on soil, groundwater and air quality of the surrounding region...

BACKGROUND: Group 2 innate lymphoid cells (ILC2s) represent a new innate effector leukocyte population that mediates type-2 immune response. However, the contribution of ILC2s to allergic rhinitis (AR) is currently not well defined. OBJECTIVE: To evaluate the potential existence and function of allergen-induced ILC2s in the experimental AR. METHODS: We established a murine model of AR using ovalbumin (OVA) and aluminium hydroxide. The OVA-induced ILC2s were sorted and purified from the mouse nasal-associated lymphoid tissue (NALT)...

Microelectromechanical (MEMS) and nanoelectromechanical systems (NEMS) are ideal candidates for exploring quantum fluids, since they can be manufactured reproducibly, cover the frequency range from hundreds of kilohertz up to gigahertz and usually have very low power dissipation. Their small size offers the possibility of probing the superfluid on scales comparable to, and below, the coherence length. That said, there have been hitherto no successful measurements of NEMS resonators in the liquid phases of helium...

Basel A Khader, Sean A F Peel, Mark R Towler
Glass polyalkenoate cements (GPCs) have potential as bio-adhesives due to their ease of application, appropriate mechanical properties, radiopacity and chemical adhesion to bone. Aluminium (Al)-free GPCs have been discussed in the literature, but have proven difficult to balance injectability with mechanical integrity. For example, zinc-based, Al-free GPCs reported compressive strengths of 63 MPa, but set in under 2 min. Here, the authors design injectable GPCs (IGPCs) based on zinc-containing, Al-free silicate compositions containing GeO₂, substituted for ZnO at 3% increments through the series...

Characterisation of anodic aluminium oxide coatings and measurement of their thickness using microscopic techniques is valuable for analysing the effectiveness of the prior anodising process. Three different methods for preparing samples to view the coating cross-section (mechanical fracturing, cryogenic fracturing and metallography) were trialled and assessed for speed of implementation, simplicity and achievable measurement accuracy. Cryogenic fracturing was found to be destructive to samples. Mechanical fracturing yielded relatively accurate coating thickness measurements and coating structural information...

This study reports the thermal analysis of a novel thermal energy storage based on high temperature phase change material (PCM) used to improve efficiency in waste-to-energy plants. Current waste-to-energy plants efficiency is limited by the steam generation cycle which is carried out with boilers composed by water-walls (i.e. radiant evaporators), evaporators, economizers and superheaters. Although being well established, this technology is subjected to limitations related with high temperature corrosion and fluctuation in steam production due to the non-homogenous composition of solid waste; this leads to increased maintenance costs and limited plants availability and electrical efficiency...
