A Gram-negative, facultatively anaerobic, rod-shaped, dissimilatory chlorate-reducing bacterium, strain AW-1(T), was isolated from biomass of an anaerobic chlorate-reducing bioreactor. Phylogenetic analysis of the 16S rDNA sequence showed 100% sequence similarity to Pseudomonas stutzeri DSM 50227 and 98.6% sequence similarity to the type strain of P. stutzeri (DSM 5190(T)). The species P. stutz...

Glycosaminoglycans (GAGs) are a heavily sulfated component of the extracellular matrix (ECM) implicated in a variety of cell signaling events involved in patterning of embryos. Embryos of the sea urchin Strongylocentrotus purpuratus were exposed to several inhibitors that disrupt GAG function during development. Treatment with chlorate, a general inhibitor of sulfation that leads to undersulfat...

Sulphated glycosaminoglycans, such as heparan sulphate, have been shown to be essential for the infectivity of many organisms. The aims of this study were to verify the role of sulphated glycosaminoglycans in chlamydial infection and to investigate whether they are present on chlamydia or chlamydial host cells. The effect of undersulphation of host cells and chlamydial elementary bodies was exa...

the reduction mechanism of molybdenum-methyl thymol blue (mtb)-chlorate system has been investigated in water on a mercury electrode. as this system is very sensitive for ultratrace determination of molybdenum, the actual mechanism involved was studied. electrochemical techniques, including dc tast polarography and cyclic voltammetry were employed. it is shown that, the cathodic wave of molybde...

PURPOSE Glycosaminoglycans (GAGs) have been implicated in the regulation of outflow resistance of aqueous humor flow through the trabecular meshwork (TM). Their role was further investigated by assessment of the effects of chlorate, an inhibitor of sulfation, and beta-xyloside, which provides a competitive nucleation point for addition of disaccharide units, in anterior segment perfusion cultur...

Heparin-binding EGF-like growth factor (HB-EGF), but not EGF, binds to cell surface heparan sulfate proteoglycan (HSPG). This was demonstrated in (a) the binding of 125I-HB-EGF to mutant CHO cells deficient in HS production was diminished by 70% compared to wild-type CHO cells, (b) the binding of 125I-HB-EGF to CHO cells and bovine aortic smooth muscle cells (BASMC) was diminished 80% by hepari...

Among the different factors hypothesized to be responsible for the virtual disappearance of Egeria densa, once a dominant aquatic macrophyte in a southern Chile wetland ecosystem, are the negative effects of certain chemical compounds (mainly chlorate) and harsh environmental conditions (desiccation caused by prolonged atmospheric exposure). The authors performed an integrated experiment in whi...

Dr Cairns said he had seen the placenta loaded with fat, and the child nevertheless healthy; whereas, in other cases, the afterbirth was apparently free from disease, and the child was still-born. He had never found much benefit from the chlorate of potass. He mentioned a case in which much good resulted from a mercurial course to both father and mother, and he was of opinion that blue pill was...

This work presents a new clock reaction based on ozone, iodine, and chlorate that differs from the known chlorate-iodine clock reaction because it does not require UV light. The induction period for this new clock reaction depends inversely on the initial concentrations of ozone, chlorate, and perchloric acid but is independent of the initial iodine concentration. The proposed mechanism conside...

Under the tropical climate of Sarawak, Edaw longan trees can be induced to flower while flowering intensity of free-flowering Diamond longan can be improved by application of chemical agents such as potassium chlorate, sodium chlorate and 'Vita-min'. The use of sodium chlorate is recommended as it is easily available and the cheapest one to use. It can be applied as a soil drench at a rate of 1...
