Like all biomolecules, chemical messengers have characteristic rates of decay and biological half-lives, and are metabolised and excreted from the body through several routes. Hierarchical control and feedback control, both positive and negative, are a fundamental feature of endocrine systems (Figure 13. It can be caused by exoge- nous administration of glucocorticoids or by adrenal adenoma, carcinoma or nodular hyperplasia. Hormone biosynthetic cells are typically of a specialised cell type, residing within a particular endocrine or exocrine gland. Endocrine hormones are secreted (released) directly into the bloodstream, while exocrine hormones are secreted directly into a duct, and from the duct they either flow into the bloodstream or flow from cell to cell by diffusion in a process known as paracrine signalling. In humans, eicosanoids are local hormones that are released by most cells, act on those same cells or nearby cells (i. They exert complex control over many bodily systems, mainly in inflammation or immunity, and act as messengers in the central nervous system. Most eicosanoid receptors are members of the G-protein-coupled receptor superfamily. The term ‘cytokine’ encompasses a large and diverse family of polypeptide regulators that are produced widely throughout the body by cells of diverse embryological origin. Historically, the term ‘cytokine’ has been used to refer to the immunomodulating agents (interleukins, interferons, etc. Classic protein hormones circulate in nanomolar (10−9) concentrations that usually vary by less than one order of magnitude. The widespread distribution of cellular sources for cytokines may be a feature that differentiates them from hormones. Virtually all nucleated cells, but especially endo/epithelial cells and resident macrophages, are potent producers of certain cytokines. In contrast, classic hormones, such as insulin, are secreted from discrete glands (e. As of 2008, the current terminology refers to cytokines as ‘immunomodulating agents’. Their name is derived from their ability to induce directed chemotaxis in nearby responsive cells; they are chemotactic cytokines. Peptide messengers interact with cell-surface receptors (peptides do not cross the membrane), whereas steroid- and lipid-derived messengers diffuse across the cell membrane and interact with intra- cellular receptors. Ligand-gated ion-channel receptors are a class of receptor that may occur either at the cell surface or within the cell. Recognition of the initial signal initiates signal transduction, an ordered sequence of bio- chemical reactions. Such processes are usually rapid, lasting in the order of milliseconds in the case of ion flux, minutes for the activation of protein- and lipid-mediated kinase cascades, or hours and even days for gene expression. The number of proteins and other molecules par- ticipating in the signal transduction event increases as the process emanates from the initial stimulus, resulting in a signal cascade; thus a small stimulus elicits a large response, referred to as signal amplification. Signal transduction is initiated when the chemical messenger, the ligand, binds to its specific receptor at the cell surface. Transmission of the signal across the plasma membrane is induced by a change in the shape (the conformation) of the intracellular domain of the receptor.

The very nature of genetic testing is that it yields information about genetic relatives buy bactroban 5 gm visa acne 5 days past ovulation, so purchase bactroban online pills acne lesions, by mere force of circumstance buy bactroban 5 gm low price skin care 50th and france, genetic relatedness (or at least non-relatedness), and hence identity, will be revealed. In sum, the argument that genetic knowledge is im- portant for identity is not conclusive, although it may gain strength as genetic heritage becomes more important. If it proves to be the case that secrecy is damaging to the family and so to the best interests of the child, a crucial justiWcation for maintaining secrecy will be undermined. Two main reasons are suggested as to why secrecy is damaging to the family unit: Wrst, that the secret will unintentionally be revealed; and second, that keeping secrets within a family is harmful in itself. The Wrst and most obvious reason is the danger that the secret will come out, either directly, when it is told, or indirectly, in that the child growing up will form certain suspicions. Given that these people are likely to have told one further person, it is probable that far more people know than couples are aware of, all of whom could potentially reveal the secret. Indeed, the fact that couples, who have told others, but not their oVspring, often regret telling anyone can probably be attributed to fear of their secret being revealed (Nachtigall et al. If this happens the chances of a breakdown in the relationship between the parents and the child, even to the extreme point where the child rejects the non-genetic father, are much greater. The second reason for rejecting secrecy is more contentious and philo- sophically debatable – namely, that secrecy is damaging in itself; that the simple awareness of a secret, even if it is never exposed, is harmful. Proving such a claim is diYcult, not only because there is no evidence one way or the other, but also because such an absolutist position is so controversial. While it could be argued that some of these lies are less serious, such as those to an employer (which may be omissions rather than lies), lying to the child is controversial and the point at which it could be claimed that family relationships are in danger of being harmed. While it may have been possible in the 1940s simply to lie during the procedure and when registering the birth, it is far less likely in the present climate that one will be able to avoid lying to the child. Given this, and for the purposes of exploring the issue, lying rather than non-disclosure and its eVect on the family and the child will now be discussed. Asserting that lying is harmful even when never discovered is a non- consequentialist claim that lying has a negative value attached to it, namely, that a lie and a truthful statement which produce the same result are not equal. First, from his formulation of the Categorical Imperative, Kant argues that the only actions which are morally justiWable are those which one would wish to be universalized: one must ‘act on that maxim which can at the same time have for its object itself as a universal law of nature’ (Kant, 1991, p. In other words, one must judge whether one’s action is moral according to whether one would wish all persons in similar situations to act in the same way, and so for the action to be the template of a moral law. Kant is unrelenting in his condemnation of lying, shown clearly in his famous example that it is wrong to lie to a murderer about the location of his 176 H. In addition to the fact that one should not lie because one would be acting according to a maxim which one would not wish to universalize (namely, that it is right to lie), Kant holds that the liar is responsible for any consequences that occur as a result of the lie. For Kant these consequences are not only the direct ones (such as if the murderer Wnds the victim as a result of the lie) but also the wider consequences which lying has on society as a whole. According to Kant, not only do the consequences of a lie aVect the individual who is lied to; the lie also harms truthfulness in general, ‘For a lie always harms another; if not some other human being, then it nevertheless does harm to humanity in general’ (Kant, 1994: pp. This is because the smooth running of society depends on assuming that people deal honestly with each other; hence ‘truthfulness is a duty that must be regarded as the basis of all duties founded on contract, and the laws of such duties would be rendered uncertain and useless if even the slightest exception to them were admitted’ (Kant, 1994: p. The second premise according to which Kant rejects lying is his dictum, connected to the Categorical Imperative, that one must ‘act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means but always at the same time as an end’ (Kant, 1991: p. This is a call to be a respecter of persons, which means granting other persons the conditions for them to be full moral agents, thereby facilitating their free autonomous moral action. Therefore, lying cannot be justiWed even for the most altruistic of reasons, as lying threatens the autonomy of moral agents by reducing their capacity to make rational and so autonomous decisions (see Kant, 1994). Keeping the truth from a person creates a power imbalance which results in the ‘lied-to’ not achieving his or her full status as a moral agent, as a possessor of freedom and reason qua person. However, most people would consider Kant’s position extreme, and there are few (both inside and outside philosophy) who would argue that it is wrong to lie to a murderer about the location of his or her victim.
