We present a case report of a 41-year-old woman of Malay ethnicity who presented with an 11-day history of fever and left-sided lymphadenopathy after consuming 'Miracle Mineral Solution' (sodium chlorite solution) for the first time. A diagnosis of Kikuchi-Fujimoto disease was established via lymph node biopsy after other differentials were excluded. The aetiology of Kikuchi-Fujimoto disease re...
the presence of microbial load and high fiber content in various non conventional feedstuffs limit their utilization in poultry feed. in the present study, the feedstuffs were treated with acidified sodium chlorite (asc) and its impact on the microbial load and metabolizable energy availability was assessed in the chickens. the effect of supplementation of feed grade enzyme was also evaluated...
indicates how intermediates between mica and chlorite might be formed. Giving Mand B+ the representative compositions [MgsAlSi301o(0H)2] and [Mg2Al(0H)e]+, the intermediate shown would have the composition KMg8AlsSi6020(0H)1o, and would have an effective interplanar distance on (001) of 24.3 A., just the sum of those for mica and chlorite. Chloritebrucite intermediates would probably be unstabl...
A new clock reaction based on chlorate, iodine and nitrous acid is presented. The induction period of this new clock reaction decreases when the initial concentrations of chlorate, nitrous acid and perchloric acid increase, but it is independent on the initial iodine concentration. The proposed mechanism is based on the LLKE autocatalytic mechanism for the chlorite-iodide reaction and the initi...
The Mars Exploration Rover Spirit investigated the igneous and alteration mineralogy and chemistry of Home Plate and its surrounding deposits. Here, we focus on using thermochemical modeling to understand the secondary alteration mineralogy at the Home Plate outcrop and surrounding Columbia Hills region in Gusev crater. At high temperatures (300 °C), magnetite occurs at very high W/R ratios, bu...
In this paper, the chlorite geothermometry method is used to estimate the low and medium temperature of metamorphism in Zavarijan area, northeast of Boroujerd. Structural formula recalculation for chlorite samples, based on 14 oxygen, show that Si cation numbers are less than 2.91(apfu), and the sum of octahedral cations is very close to 12(apfu), therefore both of them show an indication of tr...
Chlorite-coats on quartz surfaces are ubiquitous in various sedimentary environments. shield the surface of from cement overgrowths, thus preserving anomalously high porosity deeply buried sandstone reservoirs. The inhibition implies that chlorite-coats grains can significantly influence physicochemical behavior grains. Therefore, failure to notice initial thin microscale coatings forming durin...
The chemical, morphological and mineralogical properties of two Enon sandy loam (fine, mixed, thermic Ultic Hapludalfs) soilsaprolite profiles, one formed on gabbro and the other on metagabbro, are compared. Clay skins are scarce and stress cutans common in the argillic horizons of these soils. Iron-manganese concretions are concentrated in soil horizons immediately above the argillic horizons....
Chlorination by-products (CBPs) in drinking water have been associated with an increased risk of adverse pregnancy outcomes, including small for gestational age at term (term-SGA) and preterm delivery. Epidemiological evidence is weakened by a generally inaccurate exposure assessment, often at an ecological level. A case control study with incident cases was performed in nine Italian towns betw...
