We argue that the mandatory moral bioenhancement of psychopaths is justified as a prescription of social morality. Moral bioenhancement is legitimate when it is justified on the basis of the reasons of the recipients. Psychopaths expect and prefer that the agents with whom they interact do not have certain psychopathic traits. Particularly, they have reasons to require the moral bioenhancement of psychopaths with whom they must cooperate. By adopting a public reason and a Kantian argument, we conclude that we can justify to a psychopath being the recipient of mandatory moral bioenhancement because he has a reason to require the application of this prescription to other psychopaths...

We have argued for an urgent need for moral bioenhancement; that human moral psychology is limited in its ability to address current existential threats due to the evolutionary function of morality to maximize cooperation in small groups. We address here Powell and Buchanan's novel objection that there is an 'inclusivist anomaly': humans have the capacity to care beyond in-groups. They propose that 'exclusivist' (group-based) morality is sensitive to environmental cues that historically indicated out-group threat...

Bioenhancers can increase the bioavailability of metabolism susceptible drugs. The present study was designed to understand the impact of bioenhancer on permeability and bioavailability of a biopharmaceutical drug disposition classification system (BDDCS) class II drug raloxifene (RLX). RLX undergoes extensive first pass metabolism by UGT enzymes in gastrointestinal tract (GIT) and has an oral bioavailability of about 2%. Self-emulsifying drug delivery system (SEDDS) of RLX was developed using a designed approach and this formulation was loaded with reported bioenhancers: quercetin and piperine...

The continuing debate between Persson and Savulescu and myself over moral enhancement concerns two dimensions of a very large question. The large question is: what exactly makes something a moral enhancement? This large question needs a book length study and this I provide in my How to be Good, Oxford 2016. (JH 2016). In their latest paper Moral Bioenhancement, Freedom and Reason take my book as their point of departure and the first dimension of the big question they address is one that emphasizes a distinction, not highlighted in their original 2008 paper, between a moral enhancement that will ensure an improvement in morality and one that will simply make people more motivated to be moral...

In this paper we reply to the most important objections to our advocacy of moral enhancement by biomedical means - moral bioenhancement - that John Harris advances in his new book How to be Good. These objections are to effect that such moral enhancement undercuts both moral reasoning and freedom. The latter objection is directed more specifically at what we have called the God Machine, a super-duper computer which predicts our decisions and prevents decisions to perpertrate morally atrocious acts. In reply, we argue first that effective moral bioenhancement presupposes moral reasoning rather than undermines it...

Curcumin is widely available, inexpensive spice that has been used in ancient folk medicine for millennia, especially in India. Curcumin has the pharmacological properties that slow or reverse cellular proliferation and enhance apoptosis and differentiation associated with a diverse array of molecular effects. Despite its effective anticarcinogenesis properties, curcumin's poor solubility, instability, and extensive metabolism result in poor oral bioavailability. Strategies to enhance curcumin delivery include encapsulating or incorporating curcumin in a nanoparticle or microparticle drug delivery system, synthesizing more stable curcumin analogs that resist metabolism while retaining curcumin's pharmacological properties, and adding another natural product that has bioenhancing properties to curcumin or combination of two of these strategies...

The human faculty of moral judgement is not well suited to address problems, like climate change, that are global in scope and remote in time. Advocates of 'moral bioenhancement' have proposed that we should investigate the use of medical technologies to make human beings more trusting and altruistic and hence more willing to cooperate in efforts to mitigate the impacts of climate change. We survey recent accounts of the proximate and ultimate causes of human cooperation in order to assess the prospects for bioenhancement...

The conjugation of therapeutic proteins to polyethylene glycol (PEG) is known as PEGylation. It improves their retention in the body and reduces the frequency of injections. Development of noninvasive delivery systems for biopharmaceuticals can improve the patients' quality of life. The present study aimed to evaluate the cell-penetrating peptides (CPPs), which act as bioenhancers, for the nasal delivery of protein drug interferon beta (IFN-β) and its PEGylated form (PEG-IFN-β). The ability of CPPs to enhance the nasal mucosal absorption of unmodified IFN-β was assessed in rats...

Arbuscular Mycorrhizal Fungi (AMF) live in symbiosis with most crop plants and represent essential elements of soil fertility and plant nutrition and productivity, facilitating soil mineral nutrient uptake and protecting plants from biotic and abiotic stresses. These beneficial services may be mediated by the dense and active spore-associated bacterial communities, which sustain diverse functions, such as the promotion of mycorrhizal activity, biological control of soilborne diseases, nitrogen fixation, and the supply of nutrients and growth factors...

Moral bioenhancement is the potential practice of manipulating individuals' moral behaviors by biological means in order to help resolve pressing moral issues such as climate change and terrorism. This practice has obvious ethical implications, and these implications have been and continue to be discussed in the bioethics literature. What have not been discussed are the epistemological implications of moral bioenhancement. This article details some of these implications of engaging in moral bioenhancement. The argument begins by making the distinction between moral bioenhancement that manipulates the contents of mental states (e...
