Water droplets falling onto finished fabrics can create spots which can spoil the appearance of the fabric. This study compares
the propensity of softened filament polylactic acid and polyester fabrics to exhibit the adverse affects of ‘water-spotting’,
and to identify suitable softeners and methods for their application to minimise and eliminate the problem. The degree of
water spotting was greater on softened polylactic acid fabrics than on softened polyester fabrics. Polylactic acid and polyester
fabrics with hydrophobic properties did not exhibit any water spotting. Softeners applied by an exhaustion process resulted
in a finished fabric which exhibited no water spotting for either dyed polylactic acid or dyed polyester fabrics. The softening
active agent was not responsible for the water spotting. The other components in the softener formulation (such as emulsifier,
wetting agent), which carries the unfixed dyes with water, were found to be responsible. The water spot halo disappeared after
a single machine laundering process. 相似文献

The structure of BPSL1549, a protein of unknown function from Burkholderia pseudomallei, reveals a similarity to Escherichia coli cytotoxic necrotizing factor 1. We found that BPSL1549 acted as a potent cytotoxin against eukaryotic cells and was lethal when administered to mice. Expression levels of bpsl1549 correlate with conditions expected to promote or suppress pathogenicity. BPSL1549 promotes deamidation of glutamine-339 of the translation initiation factor eIF4A, abolishing its helicase activity and inhibiting translation. We propose to name BPSL1549 Burkholderia lethal factor 1. 相似文献

Characterization of the first two viruses described from wild populations of hammer orchids (Drakaea spp.) in Australia 下载免费PDF全文

Sequences representing the genomes of two distinct virus isolates infecting wild plants of two members of the genus Drakaea (hammer orchids) in Western Australia are described. The virus isolated from Drakaea livida has a bipartite genome of 4490 nt (RNA1) and 2905 nt (RNA2) that shares closest sequence and structural similarity to members of the genus Pecluvirus, family Virgaviridae, described from legumes in the Indian subcontinent and West Africa. However, it differs from pecluviruses by lacking a P39 protein on RNA2 and having a cysteine‐rich protein gene located 3′ of the triple gene block protein genes. It is the first peclu‐like virus to be described from Australia. The name Drakaea virus A is proposed (DVA; proposed member of the family Virgaviridae, genus unassigned). The second virus isolate was identified from Drakaea elastica, a species classed as endangered under conservation legislation. The genome sequence of this virus shares closest identity with isolates of Donkey orchid symptomless virus (DOSV; proposed member of the order Tymovirales, family and genus unassigned), a species described previously from wild Caladenia and Diuris orchids in the same region. These viruses are the first to be isolated from wild Drakaea populations and are proposed to have an ancient association with their orchid hosts. 相似文献
