The environment can elicit biological responses such as oxidative stress (OS) and inflammation as a consequence of chemical, physical, or psychological changes. As population studies are essential for establishing these environment-organism interactions, biomarkers of OS or inflammation are critical in formulating mechanistic hypotheses. By using examples of stress induced by various mechanisms, we focus on the biomarkers that have been used to assess OS and inflammation in these conditions. We discuss the difference between biomarkers that are the result of a (...) chemical reaction (such as lipid peroxides or oxidized proteins that are a result of the reaction of molecules with reactive oxygen species) and those that represent the biological response to stress, such as the transcription factor NRF2 or inflammation and inflammatory cytokines. The high-throughput and holistic approaches to biomarker discovery used extensively in large-scale molecular epidemiological exposome are also discussed in the context of human exposure to environmental stressors. We propose to consider the role of biomarkers as signs and to distinguish between signs that are just indicators of biological processes and proxies that one can interact with and modify the disease process.

Eyal et al have recently argued that researchers should consider conducting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) human challenge studies to hasten vaccine development. We have conducted (J. L.) and overseen (L. D.) human challenge studies and agree that they can be useful in developing anti-infective agents. We also agree that adults can autonomously choose to undergo risks with no prospect of direct benefit to themselves. However, we disagree that SARS-CoV-2 challenge studies are ethically appropriate at this time, for (...) 3 reasons: (1) current scientific knowledge of SARS-CoV-2 infection is insufficient to manage risks; (2) autonomous decision making, while necessary, does not override concerns about risk; and (3) undertaking challenge studies now would imperil confidence in the research enterprise, potentially undermining the global response to the coronavirus disease 2019 (COVID-19) pandemic.

Ang mga pelikula ng viva max ay namayagpag mula ng magkaroon ng lockdown sa Pilipinas. Sa yugtong ito, nagpalabas ang viva films ng mga pelikula sa pamamagitan ng aplikasyong viva max. Sa panonood ng mga pelikula rito, kailangan mag-subscribe ng manonood. Ang pinakamababng subscription nito ay 149.00. Sa plan na ito, isang buwan ng makakapanood ang subscriber ng lahat ng pelikula ng viva max. Nilalayon ng pananaliksik na ito na talakayin ang kalagayan ng kababaihang gumaganap sa mga piling pelikula ng (...) viva max batay sa kanilang katangian at maging ang papel sa lipunan gamit ang lenteng feminismo. Gumamit ang mananaliksik ng thematic analysis. Sa paggamit ng metodong ito, masusing pinag-aralan at binigyang-kahulugan ang mga impormasyon at datos na susuriin. Naging sandigan din ng pananaliksik na ito ang teoryang feminismo kung saan sinuri ang katangian at papel na ginampanan ng bawat tauhang babae sa mga piling pelikula ng viva max upang mabigyang-linaw ang pagbabagong naganap sa kanilang katauhan. Maging ang dahilan nang patuloy na pagtangkilik ng mga manonood sa ganitong uri ng palabas sa kabila ng iba-ibang palabas na matatagpuan sa ilang aplikasyong katulad ng Netflix, Iflix at Disney. Hindi maikakaila na malaki pa rin ang hatak ng mga pelikula na mapapanood sa viva max. Makikita rin sa pananaliksik na ito ang iba-ibang katangian at kakayahan ng mga kababaihan na tiyak na hahangaan ng sinumang manonood. Mga katangiang hindi binibigyang pansin ng ilang manonood lalo na ng mga kalalakihan ngunit kung susuriin, ito ay nagpapakita ng mahahalagang aral na tiyak na kapupulutan ng aral. Mahalagang talakayin ang ganitong uri ng pananaliksik upang magbigay- linaw kung bakit patuloy itong tinatangkilik sa paglipas ng panahon sa kabila ng paglabas ng mga bagong panoorin. (shrink)

The case describes researchers who are seeking ethics guidance on communicating with participants in a phase-1 COVD-19 vaccine trial about FDA-authorized COVID-19 vaccines (Wilfond, Duenas, and Johnson 2023). The researchers want help choosing among three options they have identified for encouraging participants to obtain one of the authorized vaccines. We argue that research ethics consultants should consider going beyond this question to address another ethics concern the researchers might have overlooked.

Clinical researchers should help respect the autonomy and promote the well-being of prospective study participants by helping them make voluntary, informed decisions about enrollment. However, participants often exhibit poor understanding of important information about clinical research. Bioethicists have given special attention to “misconceptions” about clinical research that can compromise participants’ decision-making, most notably the “therapeutic misconception.” These misconceptions typically involve false beliefs about a study’s purpose, or risks or potential benefits for participants. In this article, we describe a misconception involving (...) false beliefs about a study’s potential benefits for non-participants, or its expected social value. This social value misconception can compromise altruistically motivated participants’ decision-making, potentially threatening their autonomy and well-being. We show how the social value misconception raises ethical concerns for inherently low-value research, hyped research, and even ordinary research, and advocate for empirical and normative work to help understand and counteract this misconception’s potential negative impacts on participants.

Philosophers of literature do not take much of an interest in autobiography.1 In one sense this is not surprising. As a certain prejudice has it, autobiography is, along with biography, the preferred reading of people who do not really like to read. The very words can conjure up images of what one finds on bookshelves in Florida retirement communities and in underfunded public libraries, books with titles like Under the Rainbow: The Real Liza Minnelli or Me: Stories of My (...) Life (Katharine Hepburn).2 Hardly rousing material, at least from the philosophical point of view. But on a moment’s reflection, it becomes clear that the initial prejudice is unfounded. Never mind the fact that there are obviously .. (shrink)
