One hundred and one consumers assessed three strawberry‐flavored yogurts, using the 9‐point hedonic scale and a purchase intent scale, both blind and with their appropriate cartons. They were then monitored for a year, to determine whether their ratings had any predictive value for their purchase behavior. It was found that the highest rated yogurts tended to be the ones that were purchased during the year. Any correspondence between rank order of rating and of purchase frequency was negligible. Predictions were better when the yogurts were rated with their cartons. The ratings were a better predictor of purchase frequency than price. Various consistency measures were also made.

These findings support the addition of omega-3 fatty acid supplementation to programs aiming to improve the metabolic status of OW children with MS, although additional research on the longer-term safety and efficacy of this treatment in this population is required.

S i n c e s eve ra l ye a r s a g o, d i ve r s e corticosteroid derivatives have been development; for example, the synthesis 3α-acetoxy-16α

In this study two new indol-steroid derivatives were synthesized. The first stage involves the synthesis of 17-(2-amino-thiazol-5-yl)-

Experimental studies indicate that some steroid derivatives have inotropic activity; nevertheless, there is scarce information about the effects of the dehydroisoandrosterone and its derivatives at cardiovascular level. In addition, to date the cellular site and mechanism of action of dehydroisoandrosterone at cardiovascular level is very confusing. In order, to clarify those phenomena in this study, a dehydroisoandrosterone derivative was synthesized with the objective of to evaluate its activity on perfusion pressure and coronary resistance and compare this phenomenon with the effect exerted by dehydroisoandrosterone. The Langendorff technique was used to measure changes on perfusion pressure and coronary resistance in an isolated rat heart model in absence or presence of dehydroisoandrosterone and its derivative. Additionally, to characterize the molecular mechanism involved in the inotropic activity induced by dehydroisoandrosterone derivative was evaluated by measuring left ventricular pressure in absence or presence of following compounds; flutamide, prazosin, metoprolol and nifedipine. The results showed that dehydroisoandrosterone derivative significantly increased the perfusion pressure and coronary resistance in comparison with the control conditions and dehydroisoandrosterone. Additionally, other data indicate that dehydroisoandrosterone derivative increase left ventricular pressure in a dose-dependent manner [1 × 10(-9)-1 × 10(-4) mmol]; nevertheless, this phenomenon was significantly inhibited by nifedipine at a dose of 1 × 10(-6) mmol. In conclusion, these data suggest that dehydroisoandrosterone derivative induces positive inotropic activity through of activation the L-type calcium channel.
