Biological Plausibility of the Pace of Creation Written in the Genesis

The purpose of this paper is to discuss the biological plausibility of the pace of creation written in the genesis. A fascinating hypothesis is made on the central role of serotonin as a guide, as the director of the phenomena that enable the best use of light by the plant world, the growth, the regulation of mood in the complex molecular interactions that characterize the varying levels of consciousness. This hypothesis provides biological interpretations of the

Tryptophan and Membrane Mobility as Conditioners and Brokers of Gut–Brain Axis in Depression

The aim of this brief narrative commentary is to discuss some aspects involved in depression. It is increasingly evident that the phenomenon of mood disorders, despite its unequivocal genetic origin, slips into a multifactorial set of biochemical and molecular events that involve the whole organism. A vast literature has provided evidence that recognizes changes in serotonergic neurotransmission in the pathophysiology of depression. In addition, an increased arachidonic acid/omega-3 fatty acid ratio, which confers to mammalian cell membranes their fluidity, is associated with the depressive state. The combination of the excessive expression of kinurenine and the increased fluidity of the membrane has never been considered in the meaning of a simultaneous effect in the determinism of the depressive condition. Furthermore, various evidence supports the relationship between intestinal microbiota and depression and confirms alterations in the microbiota in depressive pathology

Depression, osteoporosis, serotonin and cell membrane viscosity between biology and philosophical anthropology

Due to the relationship between biology and culture, we believe that depression, understood as a cultural and existential phenomenon, has clear markers in molecular biology. We begin from an existential analysis of depression constituting the human condition and then shift to analysis of biological data confirming, according to our judgment, its original (ontological) structure. In this way philosophy is involved at the anthropological level, in as much as it detects the underlying meanings of depression in the original biological-cultural horizon of human life. Considering the integration of knowledge it is the task of molecular biology to identify the aforementioned markers, to which the existential aspects of depression are linked to. In particular, recent works show the existence of a link between serotonin and osteoporosis as a result of a modified expression of the low-density lipoprotein receptor-related protein 5 gene. Moreover, it is believed that the hereditary or acquired involvement of tryptophan hydroxylase 2 (Tph2) or 5-hydroxytryptamine transporter (5-HTT) is responsible for the reduced concentration of serotonin in the central nervous system, causing depression and affective disorders. This work studies the depression-osteoporosis relationship, with the aim of focusing on depressive disorders that concern the quantitative dynamic of platelet membrane viscosity and interactome cytoskeleton modifications (in particular Tubulin and Gsα protein) as a possible condition of the involvement of the serotonin axis (gut, brain and platelet), not only in depression but also in connection with osteoporosis
