Defending plasma T3 is a biological priority

What is a Default Priority?

The notion of default priority has played a central role in default reasoning research. We show that Pearl’s Z-ranking of default rules need not always correspond to priorities. System Z can still be used for priorities, but perhaps not in the obvious manner. Rather than the Z-ranking of rules, we show that the Zrankings of the negations of the material counterparts of rules correspond naturall...

Biological functions of the bacteriophage T3 SAMase gene.

Certain differences between phage T3 on the one hand and T3sam- and T7 on the other hand indicate that the T3-coded SAMase function is responsible (i) for the development of the pseudolysogenic state by preventing T3 DNA methylation, and (ii) for the partial protection of the phage DNA against restriction by the P system.

Clofibrate increases hepatic triiodothyronine (T3)- and thyroxine (T4)-glucuronosyltransferase activities and lowers plasma T3 and T4 concentrations in pigs.

In rats, clofibrate acts as a microsomal enzyme inducer and disrupts the metabolism of thyroid hormones by increasing hepatic glucuronidation of thyroxine. Whether similar effects occur in the pig has not yet been investigated. This study was performed to investigate the effect of clofibrate treatment on metabolism of thyroid hormones in pigs. To this end, an experiment with 18 pigs, which were...

Effect of ICV injection of ghrelin and leptin on T3 and T4 plasma levels in Rat

Introduction: Ghrelin, increases food intake, decreases T3 and T4 concentrations and stimulates insulin release, while leptin reduces food intake and suppresses appetite. Considering the importance of thyroid hormones, ghrelin and leptin in body metabolism, the purpose of this study was to investigate the effect of interactions between ghrelin and leptin (injected via ICV route) and plasma T...
