Here we report the draft genome sequence of strain Q-1, an iodide (I(-))-oxidizing heterotrophic bacterium in the class Alphaproteobacteria isolated from natural gas brine water. The genome sequence contained a multicopper oxidase gene probably responsible for iodide oxidation. A photosynthetic gene cluster was found but genes for carbon-fixation were absent.

Previous studies have demonstrated that short-term oral iodide administration, in doses ranging from 1500 micrograms to 250 mg/day, has an inhibitory effect on thyroid hormone secretion in normal men. As iodide intake in the USA may be as high as 800 micrograms/d, we investigated the effects of very low dose iodide supplementation on thyroid function. Thirty normal men aged 22-40 years were ran...

A rapid, simple, precise and accurate method is proposed for the determination of ternary mixtures of periodate-iodate-bromate based on their reaction with iodide ion at different pH values. The absorbance was measured at 352 nm. Three sets of reaction conditions were developed. In the first set of conditions, only periodate reacted with iodide, but in the second set the periodate and iodate re...

nitrogen is one of the most important and essential lelments for plant growth and development and it has an important role on quantitative and qualitative yield production in agriculture. this study was carried out to evaluate the effects of foliar application of nitrogen on qualitative traits of tomato fruits using a completely randomized design with five treatments and four replications under...

introduction: effective debridement of the root canal system with chemical irrigants prior to obturation is the key to long-term success of endodontic therapy. the purpose of this study is to compare the antibacterial activity of 2.5% sodium hypochlorite (naocl) and 2% iodine potassium iodide (iki) solutions as intracanal disinfectant in infected root canals during one-visit endodontic treatmen...

an experiment was conducted to investigate the effect of thyroid gland activity modulation (hyper or hypothyroidism) on energy utilization in broiler chickens. two hundred and forty one-day-old cobb broiler chicks were distributed into three dietary metabolizable energy (me) treatment groups (80 chicks each). the control group (e0) was fed basal diet (3150 kcal/kg diet), the second group (e1) w...

Rice rats were distributed by littermate into four experimental groups as follows: stannous fluoride (0.4%), iodine-sodium iodide (1.0%), a combination of iodine-sodium iodide and stannous fluoride, and a distilled water control. Each rat was treated by swabbing the molar teeth daily. All rats were fed diet 2000 and double-distilled water ad libitum, and were sacrificed after 9 weeks. Root surf...

The production of lung adenomas in strain A mice following multiple injections of 17 alkyl halides and of 3 base analogs was investigated. A slight but significant increase in the average number of lung tumors per mouse was noted following the administration of methyl iodide, n and i-propyl iodide, secand tert-butyl chloride, i-, sec-, and tert-butyl bromide, and nand sec-butyl iodide. The admi...
