The influence of alkene geometry and allylic substitution on the stereochemical outcome of intermolecular oxymercurations of allylic ethers is described. (C) 1997 Published by Elsevier Science Ltd.

The palladium-catalyzed carbocyclization of allene-diene derivatives leading to the stereospecific formation of various 4-substituted [4.3.0] and [5.3.0] bicyclic systems is presented. Different functionalities were introduced at the C-4 position of the bicyclic systems by using a range of external ...

Regio- and stereoselective palladium-catalyzed reactions of allene-substituted 1,3-dienes 1 in acetic acid at room temperature lead to cyclization with formation of a carbon-carbon bond between the middle carbon of the allene and the terminal carbon of the 1,3-diene. Two different types of reactions...

White muscle disease (nutritional myodegeneration) of foals is a peracute to subacute myodegenerative disease affecting skeletal and cardiac muscle. It is caused by a dietary deficiency of selenium and vitamin E, usually in association with predisposing factors such as a high intake of dietary unsat...

Ataxia was diagnosed in kids from a New England goat herd. Concurrent infection with the caprine arthritis/encephalitis (CAE) virus contributed to the development of hind limb ataxia and weakness in one of the kids. Six kids from this herd had signs of hind limb ataxia and paralysis. Detailed evalua...

Previous studies demonstrated that plasma clearance of organic anions such as bilirubin, bile acid, sulfobromophthalein (BSP) and indocyanine green (ICG), was reduced from 36% (bile acid) to 55% (ICG) in fasted (3 days) horses. It is believed that a general decline in carrier-mediated hepatic uptake...

The effect of oral treatment with natural or recombinant human interferon alpha (HIA) on inflammatory airway disease in young standardbreds was assessed in a double-blind, randomized clinical trial. A total of 34 horses with nasal discharge, excess mucus in the trachea, and a persistent cough of at ...

Peritoneal fluid from 10 healthy young male Holstein calves was analyzed three times (2 to 3 days, 12 to 15 days and 27 to 30 days) during the first month of life. A new technique for collection of peritoneal fluid from calves positioned in left lateral recumbency was developed. The technique was fo...
