#1
Bjørn Hofmann
New emerging biotechnologies, such as gene editing, vastly extend our ability to alter the human being. This comes together with strong aspirations to improve humans not only physically, but also mentally, morally, and socially. These conjoined ambitions aggregate to what can be labelled "the gene editing of super-ego." This article investigates a general way used to argue for new biotechnologies, such as gene-editing: if it is safe and efficacious to implement technology X for the purpose of a common good Y, why should we not do so? This is a rhetorical question with a conditional, and may be dismissed as such...

When the bioavailability of a drug increases, a corresponding increase in the levels of that drug in the bloodstream occurs. With this, drug efficacy is augmented and the dosage required to yield a specific therapeutic effect diminishes comparably. Until recently, only a few methods have proven effective in enhancing drug bioavailability, among which are the disaggregation of micronized molecules, the use of timedrelease and topical preparations, mechanization, polymorph and crystal form selection, drug solubilisation, and the use of nanotechnology...

Ginsenoside Rh2 (Rh2) is one of the major bioactive ginsenosides in Panax ginseng. However, the oral bioavailability of Rh2 is low, with P-glycoprotein (P-gp) and CYP3A4 being reported to be the main factors. The purpose of the present study was to determine the enhancing effect of piperine on the oral bioavailability as well as bioactivity of Rh2. The inhibitory effect of piperine on P-gp and CYP3A4 was determined using a Caco-2 monolayer model and a recombinant CYP3A4 metabolic system, respectively. The pharmacokinetics of oral Rh2 (10 mg·kg-1 ) administered alone or in combination with piperine (10 and 20 mg·kg-1 ) was performed in rats...

Darunavir ethanolate (DRV) is an efficient protease inhibitor (PI) used in the treatment of human immunodeficiency virus (HIV) type-1 patients. An isocratic reversed-phase HPLC method was developed to monitor concentration of darunavir in in vitro intestinal fluid samples in everted sac absorption model in the presence of bioenhancers, viz., piperine, quercetin, naringenin. The method was validated and successfully applied to everted sac and pharmacokinetic studies in rats. The absorption profiles of DRV and apparent permeability coefficients were determined...

PURPOSE: Glycyrrhizin (GLY), an inhibitor of high-mobility group box 1 (HMGB1) protects prophylactically against Pseudomonas aeruginosa keratitis. However, the therapeutic potential of GLY to enhance an antibiotic has not been tested and is our purpose. METHODS: C57BL/6 mice (B6) were infected with a clinical isolate (KEI 1025) of P. aeruginosa and treated topically at 6 h postinfection (p.i.) with GLY or phosphate-buffered saline (PBS). Clinical scores, photography with a slit lamp, enzyme-linked immunosorbent assay, myeloperoxidase assay, bacterial plate counts, histopathology, reactive oxygen/nitrogen species (ROS/RNS) assays, and in vitro macrophage (Mφ) stimulation assays were used to assess effects of GLY treatment...

Vojin Rakić, Harris Wiseman
Rakić has serious misgivings about Wiseman's inability to frame ethical issues in the context of transcending existing realities (the 'is') with the aim of achieving what we believe is morally right (the 'ought'). This inability to think beyond the present is misguided in ethics. He also criticizes Wiseman for making the unimaginative and unsubstantiated assumption that moral bioenhancement (MBE) technologies have reached their zenith already. Rakić argues that MBE will become more effective in the time to come, that it ought to be optional for every free individual, and that it should be directed at enhancing our motivation to act in line with how we believe we ought to act...

Parkinson's disease (PD) is a multifactorial neurological disorder caused by selective dopaminergic neuronal loss. Quercetin (QC) in combination with piperine (bioenhancer) acts as potential antioxidant, anti-inflammatory and neuroprotective against 6-OHDA rat model of PD. Rats were injected 6-OHDA (8μg/2μl, saline) unilaterally, intranigrally once into right SNpc. Pre-treatment with QC (25 and 50mg/kg, p.o.) alone and combination of QC (25mg/kg, p.o.) with piperine (2.5mg/kg, p.o.) were given for 14days starting from 8th day of 6-OHDA infusion...

During the previous years, Harris Wiseman has devoted substantial attention to my stance on voluntary moral bioenhancement. He argued that he has been influenced by that position, but nonetheless criticized it. I haven't replied to his criticisms yet and wish to do so now. One of the reasons is to avoid my position being misrepresented. By replying to Wiseman's criticisms, I also wish to clarify those issues in my standpoint that might have given rise to some of the misinterpretations. With the same purpose in mind, I will demarcate my concept of voluntary moral bioenhancement from related standpoints, in particular from Persson and Savulescu's notion of compulsory moral bioenhancement that, as I argued, diminishes our freedom (of the will)...

In Unfit for the Future, Ingmar Persson and Julian Savulescu argue that our collective existetial predicment is unprecedentedly dangerous due to climate change and terrorism. Given these global risks to human prosperity and survival, Persson and Savulescu argue that we should explore the radical possibility of moral bioenhancement in addition to cognitive enhancement. In this article, I argue that moral bioenhancements could nontrivially exacerbate the threat posed by certain kinds of malicious agents, while reducing the threat of other kinds...

To gain insight into the reasons that the public may have for endorsing or eschewing pharmacological moral enhancement for themselves or for others, we used empirical tools to explore public attitudes towards these issues. Participants (N = 293) from the United States were recruited via Amazon's Mechanical Turk and were randomly assigned to read one of several contrastive vignettes in which a 13-year-old child is described as bullying another student in school and then is offered an empathy-enhancing program...

It seems, at first glance, that a Kantian ethics approach to moral enhancement would tend towards the position that there could be no place for emotional modulation in any understanding of the endeavour, owing to the typically understood view that Kantian ethics does not allow any role for emotion in morality as a whole. It seems then that any account of moral bioenhancement which places emotion at its centre would therefore be rejected. This article argues, however, that this assumption is incorrect. Given later writings by Kant on the role of sympathy, and taking into account other concerns in Kantian ethics (such as bodily integrity), it may in fact be the case that Kantian ethics would allow for an account of moral bioenhancement through emotional modulation, and that in some (rare) cases such an intervention might even be considered to be a duty...

Enzymes may offer great potentials in topical pharmaceutical applications provided that treatment conditions are controlled for efficacy and safety. In this study, the effect of alkaline protease produced by recombinant Bacillus subtilis cells on the ex-vivo permeability of rabbit ear skin was investigated under different conditions of enzyme activity (5-60 units) and exposure time (15-60min). Data for transepidermal water loss (TEWL) and permeation of a hydrophilic dye, rhodamine B (Rb), indicated biphasic activity-dependent and exposure time-dependent skin permeability...

Biological effects of rutin bioactive are limited due to its poor oral bioavailability and its degradation in aqueous environments. For the purpose of bioenhancement, different nanoemulsion systems of rutin were developed by aqueous titration method using water as dispersion media. The nanoemulsion systems were characterized for surface morphology, droplet size, polydispersity index, zeta potential, in vitro release profile and the formulations were optimized. The anticancer potential of optimized nanoemulsion was evaluated by cells viability (MTT) assay, nuclear condensation, and ROS activity using human prostate cancer (PC3) cell line...

A major challenge for agriculture is to provide sufficient plant nutrients such as phosphorus (P) to meet the global food demand. The sufficiency of P is a concern because of it's essential role in plant growth, the finite availability of P-rock for fertilizer production and the poor plant availability of soil P. This study investigated whether biofertilizers and bioenhancers, such as arbuscular mycorrhizal fungi (AMF) and their associated bacteria could enhance growth and P uptake in maize. Plants were grown with or without mycorrhizas in compartmented pots with radioactive P tracers and were inoculated with each of 10 selected bacteria isolated from AMF spores...

In this article, we consider contexts or domains in which (future) moral bioenhancement interventions possibly or most likely will be implemented. By looking closely at similar or related existing practices and their relevant ethical frameworks, we hope to identify ethical considerations that are relevant for evaluating potential moral bioenhancement interventions. We examine, first, debates on the proper scope of moral education; second, proposals for identifying early risk factors for antisocial behaviour; and third, the difficult balancing of individual freedom and third party concerns in (forensic) psychiatry...

The term "moral bioenhancement" conceals a diverse plurality encompassing much potential, some elements of which are desirable, some of which are disturbing, and some of which are simply bland. This article invites readers to take a better differentiated approach to discriminating between elements of the debate rather than talking of moral bioenhancement "per se," or coming to any global value judgments about the idea as an abstract whole (no such whole exists). Readers are then invited to consider the benefits and distortions that come from the usual dichotomies framing the various debates, concluding with an additional distinction for further clarifying this discourse qua explicit/implicit moral bioenhancement...
