Chemokines are small proteins (7-16kDa) that act at G protein-coupled receptors to regulate a variety of physiological and pathophysiological processes1,2). The human immunodeficiency virus Type 1 (HIV-1) principally uses CCR5 and CXCR4 chemokine receptors as coreceptors with CD4 to gain entry into target cells3,4). Therefore, a molecule that binds to the CCR5 receptor could potentially prevent...

A new species of Ulocladium was isolated from diseased leaves from two Cucumis sp. growing in Sinkiang and Gansu provinces of China. Conidia were isolated from necrotic leaves and used to establish single-spore pure cultures. Conidia were harvested from cultures 7 d after incubation for morphological comparisons. The morphology of this species resembles that of U. botrytis and U. consortiale. H...

Results The data analyzed so far revealed the presence of different pollen and fungal species at both sites. The ratio between the pollen and fungal spores was 1:5. The airborne pollen grains showed quantitative and qualitative differences between the two sites. At FD site, the major pollen grains included Phoenix dactylifera (31%), grass pollen (14%), Atriplex nummularia (12%), Amaranthus viri...
