Reactions of iodine and phenol were investigated to determine which iodophenols were produced and their odor properties. The research was performed in support of the USA space program that applies iodine to disinfect potable water for spacecraft use. Higher concentrations (50 mg/l) and higher iodine:phenol (e.g. 10:1) ratios resulted in the formation of greater iodophenol concentrations and higher substituted iodophenols. The reactions were fast and nearly complete within 1 hour. For pH 5.5 and 8 and all iodine:phenol ratios, formation of monosubstituted compounds indicated that 2-iodophenol was favored over 4-iodophenol. At the intermediate iodine:phenol ratios of 1:1 and 2:1, substantial amounts of the diiophenols formed and persisted for up to 32 days. The diiodophenols were not detected at iodine:phenol ratios of 0.2:1 and 10:1. The compound 2,4,6-triiodophenol was the major product formed at a 10:1 iodine:phenol ratio and the formation of this trisubstituted phenol appeared nearly complete. Odor evaluation indicated that the iodophenols have much lower odor threshold concentrations (OTC) than phenol. The 2- and 4- iodophenol had OTC values of ≅ 1 and 500 μg/l, respectively, with odors described as “medicinal, phenol, chemical”.

Ulcerative colitis (UC) is a biologically complex condition characterized by chronic, relapsing inflammation of the gastrointestinal tract. The relative incidence of this debilitating condition is increasing and sociologically damaging outcomes are a continued reality. Several etiological theories for UC are currently under investigation, spanning between genetic and environmental determinants. From an environmental perspective, previous literature reviews have demonstrated the independent effectiveness of specific diet and exercise patterns in modifying UC immuno-pathophysiology. This article explores the synergistic role of diet and aerobic exercise in the prevention, pathogenesis, and management of UC in the context of recent immunological research. Through a unifying mechanism—that is, microbial influence of colonic inflammation and immuno-pathophysiology—the simultaneous reduction of pro-inflammatory dietary sulfurous amino acid intake (ie methionine, cysteine, homocysteine, and taurine) and the upregulation of aerobic exercise frequency (which spurs the colonization of anti-inflammatory butyrate, acetate, and propionate producing microbial taxa) demonstrate the clinical efficacy of incorporating both diet and exercise modifications for UC prevention and management through pathogenic alterations.

Abstract The L-Shaped distribution of estimated QTL effects (R2) has long been reported. We recently showed that a metabolic mechanism could account for this phenomenon. But other nonexclusive genetic or nongenetic causes may contribute to generate such a distribution. Using analysis and simulations of an additive genetic model, we show that linkage disequilibrium between QTL, low heritability, and small population size may also be involved, regardless of the gene effect distribution. In addition, a comparison of the additive and metabolic genetic models revealed that estimates of the QTL effects for traits proportional to metabolic flux are far less robust than for additive traits. However, in both models the highest R2's repeatedly correspond to the same set of QTL.
