The effect of vitamin E intake on indicators of muscle integrity was studied in exercised horses. Nineteen horses were blocked by sex and then assigned to one of three diets: no supplemental vitamin E (BASAL), BASAL plus 80 IU of supplemental vitamin E/kg DM (80), or BASAL plus 300 IU of supplemental vitamin E/kg DM (300). The BASAL diet contained less than 44 IU of vitamin E/kg DM, but it was ...

A reactivity difference based on the position of substituents on cyclohexa-1,3- diene was observed for the title reaction. The effect of water as solvent was more distinct for 1-methyl-4-isopropylcyclohexa-1,3-diene than for 2-methyl-5-isopropylcyclohexa- 1,3-diene or non-substituted cyclohexa-1,3-diene. The effect of NaCl (salting-out) and guanidium chloride (salting-in) was also large for 1-m...

Frying oils showed an increase in Peroxide Value (PV) at the initial stages of the frying process followed by a decrease, and there was no correlation between PV and Total Polar Compounds (TPC) in the same set of frying oils. All the frying oils had PVs lower than 4.42 meq O2 kg -1 oil during the frying process and, consequently, none of them was above the limit of 10 meq O2 kg -1 oil for edibl...

Enyne metathesis is a bond reorganization of an alkene and an alkyne to produce a 1,3-diene (eqs 1 and 2 in Scheme 1). It has been used in both intramolecular and intermolecular applications. Enyne metathesis bears a mechanistic kinship to alkene metathesis; however, it is less-studied than alkene metathesis. The enyne bond reorganization is atom economical and is driven by the enthalpic stabil...

A number of strains purporting to belong to the species Sporothrix schenckii were examined for their fatty acid content. The majority of the strains were isolated from cases of sporotrichosis. Two strains were reputedly saprophytic. In all cases except the two saprophytic ones the major fatty acid was a C18 diene. Considerable amounts of palmitic acid and C18 monoene were found in all strains.

A mild and efficient stereoselective synthesis of hexacyclic indole alkaloids with a tetrahydro-β-carboline motif has been developed by utilizing the Pictet-Spengler reaction and tandem N-acylation followed by intramolecular Diels-Alder cyclization. Initially, a diene unit was installed in the tetrahedron β-carboline skeleton through Pictet-Spengler cyclization of the corresponding aldehyde wit...

Hepatic drug-metabolizing enzymes can be inhibited or stimulated by a large number of chemicals, including drugs, pesticides, food additives and polycyclic hydrocarbons (Sher, 1971). Anabolic and progestational steroids have been found to be inducers of drug metabolism in the liver (Juchau & Fouts, 1966; Solymoss et al., 1970); however little is known about any such effects of glucocorticoids. ...
