RESUMO

Mere inability, which refers to what persons are naturally unable to do, is traditionally thought to be distinct from unfreedom, which is a social type of constraint. The advent of biomedical enhancement, however, challenges the idea that there is a clear division between mere inability and unfreedom. This is because bioenhancement makes it possible for some people's mere inabilities to become matters of unfreedom. In this paper, I discuss several ways that this might occur: first, bioenhancement can exacerbate social pressures to enhance one's abilities; second, people may face discrimination for not enhancing; third, the new abilities made possible due to bioenhancement may be accompanied by new inabilities for the enhanced and unenhanced; and finally, shifting values around abilities and inabilities due to bioenhancement may reinforce a pre-existing ableism about human abilities. As such, we must give careful consideration to these potential unfreedom-generating outcomes when it comes to our moral evaluations of bioenhancement.

RESUMO

Persson and Savulescu argue that moral bioenhancement is not only morally permissible; in some cases, it is morally obligatory. In this article, I introduce a new reason to worry about moral enhancement. I adapt the disability concept of misfit to show how moral enhancement could cause extreme moral disempowerment to those enhanced, which would result in moral injury. I argue that any safety framework that guides the development of moral bioenhancement must be sensitive to the problem of moral misfitting. I present the best case for moral bioenhancement before turning to my own worry concerning the development of moral bioenhancement and its practical implications. Finally, I consider a series of objections and responses.

RESUMO

Psychological literature indicates that actions performed with the assistance of cognition-enhancing biomedical technologies are often deemed to be less praiseworthy than similar actions performed without such assistance. This study examines (i) whether this result extends to the bioenhancement of moral capacities, and (ii) if so, what explains the effect of moral bioenhancement on perceived praiseworthiness. The findings indicate that actions facilitated by morally bioenhanced individuals are considered less deserving of praise than similar actions facilitated by 'traditional' moral enhancement-for example, moral self-education. This diminished praise does not seem to be driven by an aversion to (moral) bioenhancement per se. Instead, it appears to be primarily attributable to a perceived lack of effort exerted by bioenhanced individuals in the course of their moral enhancement. Our findings advance the philosophical discourse on the foundations of praise in the context of moral bioenhancement by elucidating the empirical basis underlying some assumptions commonly employed to argue for or against the permissibility of moral bioenhancement.

RESUMO

The development of signal enhancement technology in optical fiber biosensors is beneficial for the accurate measurement of low-concentration samples. Here, a localized surface plasmon resonance (LSPR)-based fiber biosensor combining a slide-type fiber structure (thus named WaveFlex Biosensor) and low-dimensional materials is proposed for alpha-fetoprotein (AFP) detection. A symmetric transverse offset splicing technology was used to fabricate the multi-mode fiber (MMF-multi-core fiber (MCF)-MMF structure. Furthermore, the MMF on one side was prepared into an S-taper, forming a slide-type fiber structure to generate more energy leakage. The LSPR signal generated by gold nanoparticles (AuNPs) was enhanced by the CeO2 NPs and C3N quantum dots functionalized on the fiber probe. The excellent performance of NPs was conducive to improving the sensitivity of the WaveFlex biosensor and enabling the rapid detection of samples. An AFP antibody was used to identify AFP micro-biomolecules in a specific manner. Based on the combination of the above two methods, the developed fiber probe was applied to detect AFP, and the sensitivity and limit of detection were 32 pm/(ng/mL) and 6.65 ng/mL, respectively. The experimental results demonstrate that the signal-enhanced AFP WaveFlex biosensor has great potential for the rapid and accurate detection of AFP.

RESUMO

Biodiesel is considered as one of the most promising alternative fuels due to the depletion of fossil fuels and the need to cope with potential energy shortages in the future. This article provides a thorough analysis of biodiesel synthesis, covering a variety of topics including oil feedstock, synthesis methods, catalysts, and enhancement technologies. Different oil feedstock for the synthesis of biodiesel is compared in the review, including edible plant oil, non-edible plant oil, waste cooking oil, animal fat, microbial oil, and algae oil. In addition, different methods for the synthesis of biodiesel are discussed, including direct use, blending, thermal cracking, microemulsions, and transesterification processes, highlighting their respective advantages and disadvantages. Among them, the transesterification method is the most commonly used and a thorough examination is given of the benefits and drawbacks of utilizing enzymatic, heterogeneous, and homogeneous catalysts in this process. Moreover, this article provides an overview of emerging intensification technologies, such as ultrasonic and microwave-assisted, electrolysis, reactive distillation, and microreactors. The benefits and limitations of these emerging technologies are also reviewed. The contribution of this article is offering a thorough and detailed review of biodiesel production technologies, focusing mainly on recent advances in enhanced chemical reaction processes. This provides a resource for researchers to assess and compare the latest advancements in their investigations. It also opens up the potential for enhancing the value of oil feedstocks efficiently, contributing to the development of new energy sources.

RESUMO

The identification of thousands of proteins and their relative levels of expression has furthered understanding of biological processes and disease and stimulated new systems biology hypotheses. Quantitative proteomics workflows that rely on analytical assays such as mass spectrometry have facilitated high-throughput measurements of proteins partially due to multiplexing. Multiplexing allows proteome differences across multiple samples to be measured simultaneously, resulting in more accurate quantitation, increased statistical robustness, reduced analysis times, and lower experimental costs. The number of samples that can be multiplexed has evolved from as few as two to more than 50, with studies involving more than 10 samples being denoted as enhanced multiplexing or hyperplexing. In this review, we give an update on emerging multiplexing proteomics techniques and highlight advantages and limitations for enhanced multiplexing strategies.

RESUMO

Emerging reprogenetic technologies may enable the enhancement of our offspring's genes. Beyond raising ethical questions, these biotechnologies may change some aspects of future morality. In the reproductive field, biotechnological innovations may transform moral views about reproductive choices regarding what we consider to be just or even of equal standing.

RESUMO

O objetivo desta pesquisa é identificar e compreender fenomenologicamente, por meio de relato de Psicólogos de Esporte (PE) e de Coaches, em sua vivência prática, como ocorrem os processos reflexivos em sua atuação, conforme apreendidos a partir de relatos de experiências. O método de investigação escolhido foi a fenomenologia, pois oferece os recursos necessários para tal mergulho junto à experiência reflexiva. A amostra intencional foi delineada por PE e Coaches (profissionais de Educação Física que recorrem ao Coaching) em atividade em esportes de alto rendimento, que tenham atuado ou estejam atuando em modalidades esportivas coletivas e/ou individuais. Realizaram-se nove entrevistas (cinco com PE, quatro com Coaches). O acesso ao objeto desse estudo se deu por meio de entrevistas em profundidade e semiestruturadas, orientadas pela escuta suspensiva. As questões disparadoras foram formuladas com base no Procedimento Estruturado de Reflexão adaptado. Para análise das entrevistas, realizou-se uma síntese de cada relato, seguindo-se de cruzamento intencional. Como resultados, percebeu-se que PE e Coaches trazem algumas similaridades no que se refere aos modos de refletir sobre sua prática. No entanto, as experiências que eles fazem desses processos reflexivos é que podem tomar rumos distintos. Os(as) PE amparam-se na regulamentação da profissão e resguardam-se em seus apontamentos, trazendo suas experiências e reflexões sobre os processos vividos. Os(as) Coaches trazem em suas explanações um trabalho coerente, organizado e compatível com o método do Coaching. Problematizar os processos reflexivos desses profissionais permite diferenciar qualitativa e eticamente suas atuações, possibilitando o fomento multiprofissional no esporte.(AU)


The aim of this study consists in phenomenologically identifying and understanding, by the report of Sport Psychologists (SP) and coaches, in their practical experience, how would be the reflexive processes that take place in their performance, as learned from reports of their experiences. The research method chosen was phenomenology, since it offers the necessary resources for such a dive along with the reflective experience. The intentional sample was outlined by SP and coaches (Physical Education professionals who use coaching) active in high performance sports, who have or are working in collective and/or individual sports. Nine interviews were conducted (five with SP, four with coaches). Access to the object of this study took place by in-depth and semi-structured interviews, guided by suspensive listening. The triggering questions were formulated based on the adapted Structured Reflection Procedure. For the analysis of the interviews, a synthesis of each report was carried out, followed by the intentional crossing. As results, it was noticed that SP and coaches bring some similarities regarding the ways of reflecting on their practice. However, their experiences of these reflective processes are that they can take different directions. The SP are based on the regulation of the profession and guard themselves in their notes, bringing their experiences and reflections on the processes experienced. Coaches bring in their explanations a coherent, organized, and compatible work with the coaching method. Problematizing the reflective processes of these professionals allows to differentiate their actuation qualitatively and ethically, making the multiprofessional phenomenon in sport possible.(AU)

RESUMO

BACKGROUND AND AIM: The management of bleeding during endoscopic submucosal dissection (ESD) is critical and related to the procedure time. We collaborated on a new image enhancement algorithm with parameter optimization for clinical use being developed by FUJIFILM Co. and processed white light image data offline to evaluate the effectiveness of this technology. This study aims to evaluate the clinical usefulness of this technology. METHODS: Eighteen video scenes of bleeding points from five gastric ESDs were selected and processed by the new image enhancement algorithm. The time until a bleeding point was found, visibility of a bleeding point, and color abnormality of the submucosal layer were evaluated by ESD experts, ESD trainees, and endoscopy trainees. The color differences between the bleeding point and the surroundings in CIE-L*a*b* color space were calculated in the original and enhanced images. RESULTS: The time until a bleeding point was found in the enhanced videos was significantly shorter than that in the original videos (11.10 s vs 13.85 s) (P = 0.017). On a 5-point (-2 to +2) Likert scale of visibility, the enhanced image was slightly superior to the original (+0.45), and the appearance of the submucosa was comparable between images (+0.14). The color difference among the bleeding areas on the enhanced images was significantly larger than that on the original images (10.93 vs 8.36). CONCLUSION: This novel image enhancement algorithm emphasizes the color difference between a bleeding point and the surrounding area, which would help find bleeding points faster during ESD for the less experienced endoscopists.

RESUMO

The ongoing debate about moral bioenhancement (MBE) has been exceptionally stimulating, but it is defined by extreme polarization and lack of consensus about any relevant aspect of MBE. This article reviews the discussion on MBE, showing that a lack of consensus about enhancements' desirable features and the constant development of the debate calls for a more rigorous ethical analysis. I identify a list of factors that may be of crucial importance for illuminating the matters of moral permissibility in the MBE debate and which could help us move beyond the current lack of consensus. More precisely, I propose three important theoretical and normative standards that MBE should satisfy if we wish to mitigate the concerns about its utter impermissibility. Systematically assessing MBE interventions across the presented categories should provide valuable conclusions about its theoretical soundness and feasibility, its compatibility with fundamental moral norms, and its compatibility with or facilitation of socio-political goals of equality and justice.

RESUMO

Salmonella enterica is a leading cause of food-borne diseases in humans worldwide, resulting in severe morbidity and mortality. They are carried asymptomatically in the intestine or gallbladder of livestock, and are transmitted predominantly from animals to humans via the fecal-oral route. Thus, the best preventive strategy is to preemptively prevent transmission to humans by vaccinating livestock. Live attenuated vaccines have been mostly favored because they elicit both cellular and humoral immunity and provide long-term protective immunity. However, developing these vaccines is a laborious and time-consuming process. Therefore, most live attenuated vaccines have been mainly used for phenotypic screening using the auxotrophic replica plate method, and new types of vaccines have not been sufficiently explored. In this study, we used Radiation-Mutation Enhancement Technology (R-MET) to introduce a wide variety of mutations and attenuate the virulence of Salmonella spp. to develop live vaccine strains. The Salmonella Typhimurium, ST454 strain (ST WT) was irradiated with Cobalt60 gamma-irradiator at 1.5 kGy for 1 h to maximize the mutation rate, and attenuated daughter colonies were screened using in vitro macrophage replication capacity and in vivo mouse infection assays. Among 30 candidates, ATOMSal-L6, with 9,961-fold lower virulence than the parent strain (ST454) in the mouse LD50 model, was chosen. This vaccine candidate was mutated at 71 sites, and in particular, lost one bacteriophage. As a vaccine, ATOMSal-L6 induced a Salmonella-specific IgG response to provide effective protective immunity upon intramuscular vaccination of mice. Furthermore, when mice and sows were orally immunized with ATOMSal-L6, we found a strong protective immune response, including multifunctional cellular immunity. These results indicate that ATOMSal-L6 is the first live vaccine candidate to be developed using R-MET, to the best of our knowledge. R-MET can be used as a fast and effective live vaccine development technology that can be used to develop vaccine strains against emerging or serotype-shifting pathogens.

RESUMO

The application of endoscopic imaging in the biopsy of malignant laryngeal lesions is one of the current research hotspots in the medical field. Based on the narrowband imaging resolution enhancement technology, a model for postoperative examination of laryngeal malignant tumor was constructed in this paper. The article calculated the biopsy detection rate of malignant lesions and the correct biopsy detection rate of the two groups and made a statistical comparison. In the NBI mode group, the mucosal morphology and superficial mucosal microvascular morphology of the same lesion under two different modes of white light and NBI were compared, which solved the problem of data processing of cases. During the case comparison process, patients who needed biopsies to be sent for pathology were selected for inclusion in the study and were randomly divided into two groups. The coincidence rate of EUS combined with NBI diagnosis was significantly higher than that of ordinary white light gastroscopy (47.92%), and the difference was statistically significant (P=0.000 < 0.05). The experimental results compared the accuracy of the normal white light mode and the NBI mode to diagnose the nature of the lesions: according to the Kudo classification criteria, 23 cases of tumor lesions were to be diagnosed in the normal white light mode, with an accuracy rate of 69.70%, and the NBI mode was to be used to diagnose tumors. There were 81 cases of sexual lesions, with an accuracy rate of 93.94%. The NBI mode was more accurate in diagnosing the nature of the lesions under the Kudo classification standard (P < 0.05). In 64 cases, the accuracy rate was 63.63%. Under the NBI mode, 29 cases of tumor lesions were proposed to be diagnosed, and the accuracy rate was 87.88% to promote the application of NBI endoscopy in the biopsy of malignant laryngeal lesions.

RESUMO

Transhumanists and other proponents of enhancement have been criticized for their attitude to disability. Melinda Hall argues that transhumanists denigrate disabled people by devaluing interdependence and vulnerability, and implying that disabled people are dangerous. It might also be thought that further development of enhancement technologies would have bad consequences within current, ableist and otherwise oppressive social contexts. This paper responds to these objections, arguing that enhancement needn't be in conflict with disability justice. While enhancements can be used and promoted in ways that reinforce ableism and other oppression, ways of mitigating these problems might be found by drawing on ideas from the disability rights movement, and social justice movements more broadly. The development of more accessible environments, and a general openness to surprises about which traits promote well-being, can help to create conditions under which people have genuine choice over which enhancement technologies, if any, to use.

RESUMO

PURPOSE: Flexible endoscopic evaluation of swallowing (FEES®) is a standard diagnostic tool in dysphagia. The combination of FEES® and narrow band light (narrow band imaging; NBI) provides a more precise and detailed investigation method. So far, this technique could only be performed with the NBI illumination. The new version of the "professional image enhancement technique" (PIET) provides another image enhancing system. This study investigates the eligibility of PIET in the FEES® procedure. METHODS: Both techniques, NBI and PIET, were compared using a target system. Furthermore, the image enhancement during FEES® was performed and recorded with the two systems during daily routine. RESULTS: Performing an image enhancement during FEES® is possible with both systems PIET and NBI. On the target system, the contrast of the PIET showed a brighter and a more detailed picture. In dysphagia patients, no difference between PIET and NBI was detected. CONCLUSIONS: PIET proved to be non-inferior to NBI during image enhancement FEES®. So far, image enhancement FEES® was exclusively connected to NBI. With the PIET system, an alternative endoscopy technology is available for certain indications.

RESUMO

The paper represents an empirical study of public attitudes towards moral bioenhancement. Moral bioenhancement implies the improvement of moral dispositions, i.e. an increase in the moral value of the actions or character of a moral agent. The views of bioethicists and scientists on this topic are present in the ongoing debate, but not the view of the public in general. In order to bridge the gap between the philosophical debate and the view of the public, we have examined attitudes towards moral bioenhancement. The participants were people from Serbia older than 15, who voluntarily completed an online questionnaire. The questionnaire consisted of a brief introduction to moral bioenhancement, seven general questions, 25 statements about participants' attitudes towards moral bioenhancement, and five examples of moral dilemmas. The questionnaire also included questions which were used to reveal their preference of either deontology, or utilitarianism. Participants were asked to what degree they agree or disagree with the statements. The results showed that the means used to achieve moral enhancement, the level of education, and preference for deontology or utilitarianism do have an impact on public attitudes. Using exploratory factor analysis, we isolated four factors that appear to drive the respondents' attitudes toward moral bioenhancement, we named: general-closeness, fear of change, security, and voluntariness. Each factor in relationship to other variables offers new insights that can inform policies and give us a deeper understanding of the public attitudes. We argue that looking into different facets of attitudes towards moral bioenhancement improves the debate, and expands it.

RESUMO

Physical drug delivery enhancement in skin has been shown to enhance cosmeceutical actives efficacy. Among the physical drug delivery enhancement technologies, microneedle is the most commercially successful technology. However, there are pros and cons like other physical enhancement technologies including variabilities in penetration depth and lack of efficacy. In this study, three physical topical dug delivery enhancements, elongated microparticles, microneedles and dermaroller, were applied to ex vivo pig skin and compared. The model topical drug that was used is 5-Aminolevulinic acid, the most commonly used photosensitiser prodrug. The skin was pre-treated before mounting on to Franz cell diffusion apparatus. Transdermal epidermal water loss was measured, and receptor fluids were collected at 7 time points for HPLC analysis. The results show that all three technologies disrupted the skin surface. All microporation pre-treatments significantly enhanced mALA cumulative permeation over 8 h (p < 0.001), with the 24x dermaroller significantly greater than 12x dermaroller (p < 0.001) and both dermaroller treatments significantly greater than microneedles and elongated microparticles (p < 0.05). The microporation pre-treatments all significantly increased mALA deposition in the stratum corneum and deeper skin tissues compared to passive administration, with deposition increases ranging from 3.6x to 15.1x that of passive administration. The DR pretreatment showed highest enhancement ratios (amount 5-Aminolevulinic acid in skin at 8 h following pretreatment v passive) with the following order of enhancement: 24x dermaroller > 12x dermaroller > microneedles > elongated microparticles. In conclusion, physical enhancement tools such as microneedles, dermarollers and elongated microparticles demonstrated significant penetration and retention of mALA through/into piglet skin. Further study is needed to determine the cost, dose and patient compliance.

RESUMO

In this article I address the unsolved problem of how the eighteenth-century optical machine generated an illusion of spatial depth and why variations of the apparatus continued to be produced well into the twentieth century when it should have been superseded by technically superior devices such as the stereoscope. I trace, across a diverse constellation of artefacts, design themes and variations that I take as evidence of embedded artisanal knowledge. Optical machine design was inconsistent with eighteenth-century optics, as exemplified by the camera obscura and linear perspective. It reflected an emergent paradigm according to which the forms of the external world are projected by the mind upon incomplete sense data-a process of world-production that philosophers were attempting to explain using metaphors of optical devices like the concave mirror and theater stage. My emphasis on asynchronous progress is a corrective to Jonathan Crary's Foucauldian model of homogenous, successive "scopic regimes."

RESUMO

Objetivo: Evaluar el efecto de las intervenciones educativas en el conocimiento y la aplicabilidad de la electrocirugía del equipo de enfermería. Material y método: Cuasiexperimento, con evaluaciones antes y después en un solo grupo, llevado a cabo en el centro quirúrgico de un hospital universitario terciario brasileño. Se realizó en siete etapas, se aplicó un cuestionario semiestructurado para evaluar los conocimientos de los participantes. Los participantes fueron expuestos a dos intervenciones educativas (clase expositiva, dialogada y video clase) y después de cada intervención se evaluó la retención de conocimientos. También se evaluaron indicadores de la aplicación de la unidad de electrocirugía durante los procedimientos quirúrgicos. Resultados: Participaron del estudio 4 enfermeros y 28 técnicos en enfermería. Los enfermeros tenían conocimientos previos sobre el tema de la mayor parte de los tópicos. Los técnicos en enfermería, mejoraron en los ítems verificación del equipamiento y colocación de la placa. Conclusiones: Los profesionales presentaron un buen desempeño teórico pero el mismo no se refleja en la práctica porque los profesionales son reacios a realizar prácticas que no coincidan con la teoría. La realización de este tipo de investigaciones es conveniente porque les permite a los gestores la posibilidad de proponer proyectos para una mejora continua de la asistencia perioperatoria. (AU)
