    Abstract The aim of this study was to detect and characterize Giardia lamblia in animals in the UAE. Eighty-seven fecal samples were tested for G. lamblia using the conserved fragment of small subunit (SSU)-rRNA by nested PCR. Giardia-positive isolates were genotyped for assemblages A and B using assemblage specific primers of the triosephosphate isomerase (tpi) gene. Thirty samples (34.5%) were positive for G. lamblia. Conversely, neither genotype A nor B were detected using tpi genotyping on the studied samples. Further investigations are required using higher number of samples including both human and animals in the country taking into consideration the analysis of other genotypes to provide more detailed understanding about the zoonotic transmission of this parasite.

  2. Book ; Online: Surface Electronic Structures and Field Emission Currents at Sodium Overlayers on Low-Index Tungsten Surfaces

    Abstract The total energy distributions (TEDs) of the emission currents in field emission and surface photofield emission and the overlayer-induced modifications in the surface electronic structures from the technologically important W surfaces with the commensurate W(100)/Na c(2x2), W(110)/Na (2x2) and W(111)/Na (1x1) overlayers are calculated. The TEDs obtained by our recent numerical method that extends the full-potential linear augmented plane wave method for the electronic structures to the study of field and photofield emission are used to interpret the shifts of the peaks in the experimental TEDs in field emission and photofield emission from the W(100) and W(110) surfaces at sub-monolayer and monolayer Na coverage. Hybridization of the 3s Na states with the pairs of dz2-like surface states of the strong Swanson hump in clean W(100) and surface resonances in clean W(111) below the Fermi energy shifts these W states by about -1.2 eV and -1.0 eV, thus stabilizing these states, to yield new strong peaks in the TEDs in field emission and photofield emission from W(100)/Na c(2x2) and W(111)/Na (1x1) respectively. The effect of Na intralayer interactions are discussed and are shown to shift the strong s- and p-like peaks in the surface density of states of W(110) below and above the Fermi energy respectively to lower energy with increased Na coverage, in agreement with experiments.

    Abstract This study was conducted in Tamiya district, Fayoum Governorate, Egypt in three successive seasons of 2005, 2006 and 2007. Fifty seedling palm males were chosen and evaluated in order to select the suitable and most promising males of them to be used in pollinating female date palms. The results showed that there are five palm males (No. 2, 10, 29, 40 and 46) that were characterized as highly potent and that recorded the highest grades for the studied characters. These characters involved: weight and viability of pollen grains, spathes number, flowers number, start and duration of spathe burst. Accordingly, those selected palm males could be used as pollinators for date palm females and considered as recommended under the conditions of this study.

    Abstract Exposure to particulate matter (PM), a major component of air pollution, contributes to increased morbidity and mortality worldwide. PM induces innate immune responses and contributes to allergic sensitization, although the mechanisms governing this process remain unclear. Lung mucosal uric acid has also been linked to allergic sensitization. The links among PM exposure, uric acid, and allergic sensitization remain unexplored. We therefore investigated the mechanisms behind PM-induced allergic sensitization in the context of lung mucosal uric acid. PM10 and house dust mite exposure selectively induced lung mucosal uric acid production and secretion in vivo, which did not occur with other challenges (lipopolysaccharide, virus, bacteria, or inflammatory/fibrotic stimuli). PM10-induced uric acid mediates allergic sensitization and augments antigen-specific T-cell proliferation, which is inhibited by uricase. We then demonstrate that human airway epithelial cells secrete uric acid basally and after stimulation through a previously unidentified mucosal secretion system. Our work discovers a previously unknown mechanism of air pollution-induced, uric acid-mediated, allergic sensitization that may be important in the pathogenesis of asthma.

    Abstract A novel approach has been developed to calculate the temperature dependence of the optical response of a semiconductor. The dielectric function is averaged over several thermally perturbed configurations that are extracted from molecular dynamic simulations. The calculated temperature dependence of the imaginary part of the dielectric function of GaAs is presented in the range from 0 to 700 K. This approach that explicitly takes into account lattice vibrations describes well the observed thermally-induced energy shifts and broadening of the dielectric function.
