Effects of thyroid hormones on the heart.

Thyroid hormones have a significant impact on heart function, mediated by genomic and non-genomic effects. Consequently, thyroid hormone deficiencies, as well as excesses, are expected to result in profound changes in cardiac function regulation and cardiovascular hemodynamics. Thyroid hormones upregulate the expression of the sarcoplasmic reticulum calcium-activated ATPase and downregulate the expression of phospholamban.

[The legal concept of personhood in Colombia: are there biological reasons to change it?].

Nowadays, as a consequence of scientific advances in embryology, genetics and assisted reproduction techniques, the scientific community ask for new laws to establish new parameters to use with these recent discoveries. Discoveries that have changed the legal concept of "person". In many countries this concept is absolutely useless when facing new techniques such as cloning, stem cell research and embryo storage.
