Pregnancy in Women with Complex Congenital Heart Disease. A Constant Challenge.

Background: The improvement in surgical techniques has contributed to an increasing number of childbearing women with complex congenital heart disease (CCC). However, adequate counseling about pregnancy in this situation is uncertain, due to a wide variety of residual cardiac lesions.

Objectives: To evaluate fetal and maternal outcomes in pregnant women with CCC and to analyze the predictive variables of prognosis.

Contents of conjugated linoleic acid isomers in ruminant-derived foods and estimation of their contribution to daily intake in Portugal.

The present study provides a detailed overview of the contents of conjugated linoleic acid (CLA) isomers in the most consumed Portuguese CLA-rich foods (milk, butter, yoghurt, cheese, beef and lamb meat), by using silver ion-HPLC. In addition, the contribution of these ruminant-derived foods to the daily intake of CLA isomers was estimated based on Portuguese consumption habits. The total CLA concentration in milk and dairy products ranged from 4.

Synthesis, surface active and antimicrobial properties of new alkyl 2,6-dideoxy-L-arabino-hexopyranosides.

Synthesis of alkyl 2,6-dideoxy-L-arabino-hexopyranosides was accomplished by the reaction of 1,5-anhydro-2,6-dideoxy-L-arabino-hex-1-enitol with fatty alcohols in dichloromethane, catalyzed by triphenylphosphine hydrobromide. Reaction with octanol and dodecanol gave the corresponding alpha-glycosides in 50% and 42% yield, the beta-glycosides in 20% and 21% yield and the alpha-anomer of the Ferrier product in 10% and 9% yield, respectively. Deacetylation of the alpha-/beta-glycosides with sodium methoxide in methanol afforded the amphiphilic L-arabino-hexopyranosides in 94-99% yield.
