The use of technical aids has a positive impact on the autonomy and quality of life of elderly or disabled people, and is also beneficial for the caregivers and professionals who support them. Nevertheless, there are still major obstacles to their use, notably a general lack of information on technical aids. This observation led us to produce a set of information tools to help people better understand these aids and how to use them.

Corynebacterium glutamicum ATCC 13032 is a promising microbial chassis for industrial production of valuable compounds, including aromatic amino acids derived from the shikimate pathway. In this work, we developed two whole-cell, transcription factor based fluorescent biosensors to track cis, cis-muconic acid (ccMA) and chorismate in C. glutamicum. Chorismate is a key intermediate in the shikimate pathway from which value-added chemicals can be produced, and a shunt from the shikimate pathway can divert carbon to ccMA, a high value chemical. We transferred a ccMA-inducible transcription factor, CatM, from Acinetobacter baylyi ADP1 into C. glutamicum and screened a promoter library to isolate variants with high sensitivity and dynamic range to ccMA by providing benzoate, which is converted to ccMA intracellularly. The biosensor also detected exogenously supplied ccMA, suggesting the presence of a putative ccMA transporter in C. glutamicum, though the external ccMA concentration threshold to elicit a response was 100-fold higher than the concentration of benzoate required to do so through intracellular ccMA production. We then developed a chorismate biosensor, in which a chorismate inducible promoter regulated by natively expressed QsuR was optimized to exhibit a dose-dependent response to exogenously supplemented quinate (a chorismate precursor). A chorismate-pyruvate lyase encoding gene, ubiC, was introduced into C. glutamicum to lower the intracellular chorismate pool, which resulted in loss of dose-dependence to quinate. Further, a knockout strain that blocked the conversion of quinate to chorismate, also resulted in absence of dose-dependence to quinate, validating that the chorismate biosensor is specific to intracellular chorismate pool. The ccMA and chorismate biosensors were dually inserted into C. glutamicum to simultaneously detect intracellularly produced chorismate and ccMA. Biosensors, such as those developed in this study, can be applied in C. glutamicum for multiplex sensing to expedite pathway design and optimization through metabolic engineering in this promising chassis organism.

RESEARCH QUESTION
What is the attitude of Belgian women of reproductive age towards enucleated egg donation? Does the willingness of women to donate differ when they would donate enucleated or whole eggs?
DESIGN
In 2022, an online survey was conducted among a representative sample of 1000 women in Belgium aged 18-50 years. The item on willingness to anonymously donate enucleated eggs was dichotomized into those willing to donate and those not willing to donate or uncertain.
RESULTS
No statistically significant difference was found between the willingness to donate enucleated eggs and whole eggs (whether anonymously or identifiably). Anonymity, however, affected the willingness to donate, with considerably fewer women willing to donate identifiably. The respondents were divided about their parental status if they were to donate enucleated eggs, with less than one-half (44%) not considering themselves to be a genetic mother. Women willing to donate enucleated eggs anonymously were less likely to view themselves as a genetic mother of the child compared with others. Fewer than one in five considered the technique unacceptable because the resulting child would carry genetic material of three persons.
CONCLUSIONS
Women in the general population did not show a greater willingness to donate enucleated eggs than whole eggs. The fact that the respondents were strongly divided on whether or not they would consider themselves to be a genetic mother of the resulting child may explain this result. Other factors, such as the potential high risk for the child, may also have contributed to less willingness.

A number of species have recently recovered from near-extinction. Although these species have avoided the immediate extinction threat, their long-term viability remains precarious due to the potential genetic consequences of population declines, which are poorly understood on a timescale beyond a few generations. Woolly mammoths (Mammuthus primigenius) became isolated on Wrangel Island around 10,000 years ago and persisted for over 200 generations before becoming extinct around 4,000 years ago. To study the evolutionary processes leading up to the mammoths' extinction, we analyzed 21 Siberian woolly mammoth genomes. Our results show that the population recovered quickly from a severe bottleneck and remained demographically stable during the ensuing six millennia. We find that mildly deleterious mutations gradually accumulated, whereas highly deleterious mutations were purged, suggesting ongoing inbreeding depression that lasted for hundreds of generations. The time-lag between demographic and genetic recovery has wide-ranging implications for conservation management of recently bottlenecked populations.

Why were women given the right to vote? "Because it is morally wrong to deny women the right to vote." This explanation does not seem to fit the typical pattern for explaining an event: rather than citing a cause, it appeals to an ethical claim. Do people judge ethical claims to be genuinely explanatory? And if so, why? In Studies 1 (N = 220) and 2 (N = 293), we find that many participants accept ethical explanations for social change and that this is predicted by their meta-ethical beliefs in moral progress and moral principles, suggesting that these participants treat morality as a directional feature of the world, somewhat akin to a causal force. In Studies 3 (N = 513) and 4 (N = 328), we find that participants recognize this relationship between ethical explanations and meta-ethical commitments, using the former to make inferences about individuals' beliefs in moral progress and moral principles. Together these studies demonstrate that our beliefs about the nature of morality shape our judgments of explanations and that explanations shape our inferences about others' moral commitments.

This essay challenges the idea of progress as technological development in relation to medicine by focusing on people rather than things. It analyzes how the prevalence of such an idea of progress leads contemporary societies to a technofetishism that degrades community life and medical practice, contributing to the medicalization of social life. It is argued that the realization of technological potentialities depends on their forms of use, that the main motive of technological development is unlimited profit, and the priority developments are those that enhance social control which maintains the status quo. Intelligence as an intelligence quotient is criticized by proposing it as an attribute of the human being as a whole, manifested in the ways of thinking and acting of human beings in their circumstances, where affectivity and critical thinking are essential for their development; it is emphasized that its antecedent is the harmonic concert of planetary life, which contrasts with the prevailing human disharmony. It is proposed that artificial intelligence is the latest creation of technofetishism, which deposits vital attributes in technology, and that its use will accentuate the degradation of human and planetary life. Another idea of medical progress is proposed, based on forms of organization that is conducive to the development of inquisitive, critical, and collaborative skills that promote permanent improvement, whose distant horizon is dignified progress: the spiritual, intellectual, moral, and convivial sublimation of collectivities in harmony with the planetary ecosystem.

This essay questions, with regard to medicine, the idea of progress as technological development by focusing on people rather than things. It analyzes how the predominance of such an idea of progress converts today's societies to techno-fetishism that degrades community life and medical practice, contributing to the medicalization of social life. It is argued that the realization of technological potentialities depends on their forms of use; that the main motive of technological development is unlimited profit and that priority developments are those that enhance the social control that maintains the status quo. The intelligence as an intelligence quotient is criticized by proposing it as an attribute of the human being as a whole, manifested in the ways of thinking and proceeding of people in their circumstances, where affectivity and critical thinking are essential for their development; it is emphasized that its antecedent is the harmonic concert of planetary life that contrasts with the prevailing human disharmony. It is proposed that artificial intelligence is the most recent creation of techno-fetishism that deposits vital attributes in technology and that its forms of use will accentuate the degradation of human and planetary life. Another idea of medical progress is proposed, based on forms of organization conducive to the development of inquisitive, critical and collaborative skills that promote permanent improvement, whose distant horizon is dignifying progress: spiritual, intellectual, moral and convivial sublimation of collectivities in harmony with the planetary ecosystem.

Introduction Community-based primary care physiotherapy has developed through private practice, fee-for-service model in Aotearoa New Zealand where independent businesses operate in competition. Aim We aimed to explore how the private practice model of physiotherapy impacts patient care, physiotherapists, and professional behaviour. Methods Six physiotherapists managing musculoskeletal conditions in a primary care private practice in Aotearoa New Zealand were recruited using maximum variation purposive sampling. In-depth individual face-to-face semi-structured interviews were audio-recorded, transcribed verbatim, and analysed using Interpretive Description. Inductive data analysis synthesised and contextualised data, creating a thematic framework that developed across interviews. Results All physiotherapy participants discussed concerns about culture and professionalism in private practice physiotherapy despite not being asked about these. Three themes were identified. 'Competitive business model and lack of collaboration' - participants thought that competition between practices resulted in a lack of trust, collegiality, and collaboration, and pressure on clinicians to maintain income. '(Un)professional behaviour' - participants thought that physiotherapists were defensive and averse to scrutiny, resulting in reluctance to admit when they needed help, or to undertake peer review or seek second opinions. 'Lack of support and mentoring' - the professional culture in private practice was perceived to reduce support and mentoring, with negative impacts that affected physiotherapists at all stages of career. Conclusion This exploratory qualitative study suggests that competition dominates communication and collaboration in private practice physiotherapy and may have wider implications for professionalism and the quality of patient care. Competitive business models and an aversion to scrutiny may reduce collegial interaction and professional behaviour.
