New life sciences innovation and distributive justice: rawlsian goods versus senian capabilities

The successful decoding of human genome and subsequent advances in new life sciences innovation create technological presuppositions of a new possibility of justice i.e. the just distribution of both social (income, wealth, etc.) and natural (rationality, intelligence, etc.) goods. Although Rawlsians attempt to expand their theory to include this new possibility, they fail to provide plausible metrics of social justice in the genomics and post-genomics era. By contrast, Senians seem to succeed to do so through their index of basic capabilities. This paper explores what might be regarded as a Senian perspective of distributive justice in new life sciences innovation. The argument is that, by comparing freedoms (different functionings) instead of primary goods, the capability theory allows not only for the identification of injustices linked to natural lottery but also for their elimination through the use of new genomic technologies, including gene-based diagnostics, gene therapy, somatic cell engineering (SCE) and germ-line engineering (GLE). These innovative technologies seem to have the potential to reduce variability in natural goods and therefore enable individuals to convert social goods into well-being or welfare

Lithium therapy effects on the reproductive system

The chemical properties of lithium (Li) make it an extremely active substance in the body. It is active in the form of Li+ ion, so all salts have the same pharmacological action. Li salts are used to treat manic-depressive disorders (bipolar affective disorders), depressive manic symptoms that include hurried speech, hyperactivity, little need for sleep, aggression, and cholera. Li is a mood stabilizer and reduces extreme behaviors by restoring the balance of neurotransmitters in the brain. The modifications of the cAMP signaling pathway, alterations in the phosphoinositol pathway, variations in the availability of GABA and glutamate are some described mechanisms of action of Li to achieve its antimanic and mood stabilizing effects. Thus, lithium exerts modifications on the circadian rhythm, neurotransmission processes in the central nervous system, and neuroendocrine functions.Li therapies have benefits that have not yet been overtaken by other drugs. However, there is also some resistance to using these drugs, partly due to the lack of knowledge of the real impact of its adverse effects although some of them are reversible with the discontinuation of treatment. However, less known and more controversial are the toxic effects of lithium therapy on the reproductive system and, therefore, on human sexual functions. Studies in human and laboratory animals on the effects of Li have demonstrated significant effects on the functioning of the hypothalamic-pituitary gonadal axis. Therefore, this ion may alter human reproduction.Fil: Filippa, Veronica Palmira. Consejo Nacional de Investigaciones Científicas y Técnicas.
