Biodegradability of nitroxylene isomers
… were conducted beginning with three xylene isomers: ortho-xylene, meta-xylene and para-xylene; and continued with the four mononitroxylene (MNX) isomers, culminating with testing ten dinitroxylene (DNX) isomers. Soil samples were obtained from a historically contaminated site with high …

Testosterone, Lycopene Isomers, and Prostate Cancer
The objective of the final study was to determine the influence of purified lycopene, tomato powder, and 20% diet restriction on N-methyl-N-nitrosourea (NMU)-testosterone-induced prostate cancer in rats. Survival was analyzed to include only rats that died with adenocarcinomas of the accessory sex …

Separation of close isomers by enclathration
… host readily forms inclusion compounds with the isomers of phenylenediamine, benzenediol, picoline and lutidine, as well as selected solvents including methanol, ethanol, i-propanol, n-butanol, ethyl acetate and dioxane. The crystal structures of the complexes formed were elucidated, and …

The separations of picoline isomers by enclathration
The chemical and physical properties of isomers make them difficult to separate using conventional methods. This renders the separation of isomers one of the more challenging obstacles in chemistry. In these cases, the supramolecular phenomenon of host-guest chemistry may be used in order to …

Conjugated linoleic acid isomers anti-neuroinflammatory effects on activated microglial cells
Conjugated linoleic acid (CLA) isomers display anti-inflammatory effects within the central nervous system (CNS). This research examined how CLA isomers c9,t11 and t10,c12 influence fatty acid (FA) and N-acylethanolamine (NAE) profiles, along with their relationship with the expression of …

Physiological and Biochemical Aspects of Methionine Isomers and Precursors in Broilers
Methionine (Met) is an essential amino acid for animals and also the first limiting amino acid in a broiler diet. The dietary supplemental Met sources include the natural isoform L-methionine (L-Met), the synthetic form DL-methionine (DL-Met) and the synthetic Met precursor DL-2-hydroxy-4 …

Uncovering unique N-linked glycan structural isomers in cancer via MS(n) disassembly
<p>Molecular glycosylation is involved in key developmental roles including control of cell differentiation, innate immunity and signal transduction. Equally as demonstrable are numerous aspects of tumor development, from cellular proliferation to angiogenesis and metastasis. This sensitivity to …

Spectroscopic Investigation of Isomers of the CO2-CO Dimer in the 4.27 Micron Region
… mode (geared bending mode) are observed for both isomers. The spectra were fit with a semi-rigid asymmetric rotor Hamiltonian. The fundamentals were fit to b-type bands (〖ΔK〗_a=1,ΔK_c=1) and the combination bands were fit to a-type (ΔK_a=0) bands. In addition, two weak (ν_1,ν_2^(l_2 ),ν_3 )=(01^1 …

Mid Infrared Investigation of Two Isomers of the CO-N2O van der Waals Complex
… the fundamental band, combination bands for both isomers are observed and intermolecular frequencies for the out of plane torsion and the in-plane CO-rock, or disrotatory bend are reported. Vibrational assignment of these bands is achieved by comparison with data recently published (A. Barclay et …
