The effects of watercress consumption on the metabolism of nicotine in smokers were examined. Watercress is a rich source of phenethyl isothiocyanate (PEITC), an effective chemopreventive agent for cancers of the lung and esophagus induced in rodents by nitrosamines, including the tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone. PEITC is believed to inhibit nitrosamin...

Dicranella pseudosubulata Müll Hal. ex Gangulee is a moss species and member of the Dicranaceae family, which known to harbour many secondary metabolites therapeutic importance. A gas chromatography-mass spectrometry (GC-MS) analysis methanolic extract D. was obtained determine moss. The chromatogram revealed 48 compounds, four compounds showed highest concentrations, constituting 73.86% all bi...

This study explored the impacts of modified atmosphere packaging (MAP) treatment on proteolytic development and volatile compounds Domiati cheese during storage. samples were kept for 75 days at refrigerator temperature, under aerobic (C1) or vacuum (C2). In parallel, other MAP, different levels CO2 N2, as follows: 10% CO2/90% N2 (D1), 15% CO2/85% (D2), 25% CO2/75% (D3), 100% (D4), (D5). The no...

Ascaris suum eggs were inactivated in distilled water and digested sludge by butanoic, pentanoic, and hexanoic acids. The fatty acids (short-chain fatty acids [SCFA]) were effective only when protonated and at sufficient concentrations. The conjugate bases were not effective at the concentrations evaluated. Predictions from an inhibition model (50% inhibitory concentration [IC(50)]) based on qu...

A method providing a high yield (80–94%) for producing gamma-hydroxy-butanoic acids hydrazides by the interaction of various representatives cyclic esters with 85% hydrazine hydrate has been elaborated. It established that introduction gamma-hydroxypropyl residue into composition results in new biological properties.

Objectives of this study were to quantify production responses of lactating dairy cows to supplying absorbable Met as isopropyl-2-hydroxy-4-(methylthio)-butanoic acid (HMBi), or rumen-protected Met (RPM, Smartamine M; Adisseo, Alpharetta, GA) fed with or without 2-hydroxy-4-(methylthio)-butanoic acid (HMB), and to determine whether Met supplementation will allow the feeding of reduced dietary c...

Poultry operations are associated with emissions of aerial ammonia (NH3), volatile organic compounds (VOCs), and odor, and the magnitude of emissions is influenced by manure management practices. As a manure treatment additive, zeolites have been shown to have the potential to control NH3. Because of their properties it is also expected that zeolites could effectively adsorb VOCs and odor. The ...

To determine the effect of dietary methionine supplementation on intestinal amino acid/peptide/monocarboxylic acid transporter gene expression, a total of 242 male Cobb-500 broilers were fed from day of hatch to 35 d of age using a basal diet deficient in sulfur amino acids (control), or the control diet supplemented with dl-methionine (dl-Met), l-methionine (l-Met) or methionine analog dl-2-hy...
