This study reports the ability of one hyperthermophilic and two thermophilic microorganisms to grow anaerobically by the reduction of chlorate and perchlorate. Physiological, genomic and proteome analyses suggest that the Crenarchaeon Aeropyrum pernix reduces perchlorate with a periplasmic enzyme related to nitrate reductases, but that it lacks a functional chlorite-disproportionating enzyme (C...

OBJECTIVE Perchlorate is a known competitive inhibitor of the sodium/iodide symporter (NIS). Possible thyroid-related effects of environmental perchlorate have created great health concerns, especially in the US, resulting in a debated reference dose (RfD) of 0.0007 mg/kg per day in drinking water recommended by the National Academy of Sciences (NAS). However, the impact of other environmental ...

Perchlorate (ClO4 ) has been detected in numerous ground and surface waters, and has recently been added to the drinking water Candidate Contaminant List in the United States. Perchlorate can be removed from drinking water using ion exchange, but this results in the production of highly saline (7–12%) perchlorate-contaminated brines. Perchlorate-degrading microbial enrichments capable of growth...

Groundwater at the Crafton-Redlands site in Redlands, California is contaminated with perchlorate in addition to chlorinated volatile organic compounds (VOCs). VOCs are removed from extracted groundwater using granular activated carbon, which is ineffective for perchlorate removal. Side-by-side pilot-scale bioreactors for perchlorate removal from extracted groundwater were tested at the site. P...

The title compound, [Cu2(ClO4)(C14H13N2O)2(H2O)]ClO4, crystallizes as an unsymmetrical dinuclear cation bridged by the phen-oxy O atoms with one CuII atom coordinated by a water mol-ecule and the other by a perchlorate anion, thus making both CuII atoms five-coordinate, and with a further perchlorate anion present for charge balance. A long inter-action [2.9893 (5) Å] between one of the two CuI...

background: lithium has been the treatment of choice for bipolar disorder (bd) for many years. although erectile dysfunction is a known adverse effect of this drug, the mechanism of action by which lithium affects erectile function is still unknown. objective: the aim was to investigate the possible involvement of nitric oxide (no) in modulatory effect of lithium on penile erection (pe). we fur...

Perchlorate is a common aquatic contaminant that has long been known to affect thyroid function in vertebrates, including humans. More recently perchlorate has been shown to affect primordial sexual differentiation in the aquatic model fishes zebrafish and threespine stickleback, but the mechanism has been unclear. Stickleback exposed to perchlorate from fertilization have increased androgen le...

Title of Document: NEW ELECTROLYTE AND ELECTRODE MATERIALS FOR USE IN LITHIUMION BATTERIES Veidhes R. Basrur, Master of Science, 2010 Directed by: Prof. Srinivasa R. Raghavan & Prof. Chunsheng Wang Department of Chemical & Biomolecular Engineering Lithium-ion batteries have emerged as the preferred type of rechargeable batteries, but there is a need to improve the performance of the electrolyte...

Perchlorate is a known environmental contaminant, largely due to widespread military use as a propellant. Perchlorate acts pharmacologically as a competitive inhibitor of thyroidal iodide uptake in mammals, but the impacts of perchlorate contamination in aquatic ecosystems and, in particular, the effects on fish are unclear. Our studies aimed to investigate the effects of concentrations of ammo...
