“…One of the protective responses triggered with stress is the induction of stress proteins known as heat shock proteins (HSPs). When cells are exposed to sublethal stress, inducible forms of HSPs are upregulated, resulting in the acquisition of greater stress resistance 51. In fact, the HSP level has been reported to be increased markedly 2–7 days after a single bout of non‐damaging, aerobic exercise in exercised skeletal muscles 52, 53.…”

“…2 In addition to these well-characterized intracellular functions of HSPs, researchers have suggested that extracellular HSPs enhance the immune system. 3 The most inducible and abundant, and therefore most studied, is HSP72, which was reclassified recently as HSPA1A.…”

Context: Conditions such as osteoarthritis, obesity, and spinal cord injury limit the ability of patients to exercise, preventing them from experiencing many well-documented physiologic stressors. Recent evidence indicates that some of these stressors might derive from exercise-induced body temperature increases.Objective: To determine whether whole-body heat stress without exercise triggers cardiovascular, hormonal, and extracellular protein responses of exercise.Design: Randomized controlled trial. Setting: University research laboratory. Patients or Other Participants: Twenty-five young, healthy adults (13 men, 12 women; age = 22.1 ± 2.4 years, height = 175.2 ± 11.6 cm, mass = 69.4 ± 14.8 kg, body mass index = 22.6 ± 4.0) volunteered.Intervention(s): Participants sat in a heat stress chamber with heat (73°C) and without heat (26°C) stress for 30 minutes on separate days. We obtained blood samples from a subset of 13 participants (7 men, 6 women) before and after exposure to heat stress.Main Outcome Measure(s): Extracellular heat shock protein (HSP72) and catecholamine plasma concentration, heart rate, blood pressure, and heat perception. Results: After 30 minutes of heat stress, body temperature measured via rectal sensor increased by 0.8°C. Heart rate increased linearly to 131.4 ± 22.4 beats per minute (F 6,24 = 186, P < .001) and systolic and diastolic blood pressure decreased by 16 mm Hg (F 6,24 = 10.1, P < .001) and 5 mm Hg (F 6,24 = 5.4, P < .001), respectively. Norepinephrine (F 1,12 = 12.1, P = .004) and prolactin (F 1,12 = 30.2, P < .001) increased in the plasma (58% and 285%, respectively) (P < .05). The HSP72 (F 1,12 = 44.7, P < .001) level increased with heat stress by 48.7% ± 53.9%. No cardiovascular or blood variables showed changes during the control trials (quiet sitting in the heat chamber with no heat stress), resulting in differences between heat and control trials.Conclusions: We found that whole-body heat stress triggers some of the physiologic responses observed with exercise. Future studies are necessary to investigate whether carefully prescribed heat stress constitutes a method to augment or supplement exercise.

“…Heat shock proteins are among the main "violators" of the host's oral tolerance. Under stress conditions, these proteins, which induce the coagulation of cell proteins, promote an increase in the cell resistance to unfavorable factors of environment; this feature gave origin to the term stress proteins [22].…”

What are symbiotic systems? In this short paper, the workshop chairs describe the focus of this workshop and elaborate on the definition of symbiotic human-machine relation. Symbiotic relationships are probably most known from biology. In a symbiotic relationship between animals and/or plants, some organism closely interacts with another type of organism to ensure its own survival, so that both end up sharing the same habitat [3]. This biological phenomenon, exemplifying a very tight kind of relationship, is used metaphorically 1 to characterize a growing part of the current human-machine relations, where machines collect users' data that are not even available to the human conscious cognition (e.g. brain signals, social data collected on the web), and then elaborate solutions and make decisions based on such data. Here machines are so interconnected to humans that the term interaction sounds like an understatement [13]. After the pioneering discussion on men-computer [sic] symbiosis stimulated in the early 60 by J.C.R. Licklider [9], the reference to symbiotic human-machine interaction appeared again around 2013 in a European Union ICT workprogram stressing that concept 2 and has grown ever since, as is partly documented in the Symbiotic Interaction workshops and proceedings [2, 5]. Surely, in the field of human-computer interaction as well as in philosophy and sociology of technology, the close connection between humans and machines has been emphasized several times: by the concepts of artifacts and embodied cognition, where the propriety of a technology depends on the users' needs and the users' ability depends in turn on the tools s/he is endowed with (e.g., [7]); by the notion of sociotechnical systems, where a technology inevitably includes some symbolic, politic elements as part of the package (e.g., [8]); by the idea of humans as hybrids or cyborgs, which finds real-life incarnations in medical prosthesis and augmentation devices (e.g., [1]). However, the term symbiotic emphasizes a noteworthy change 1 Of course, a metaphor is able to illuminate some aspects of a domain by similarity with some other domain [12], but not all aspects. Where the biological metaphor stops is in referring to two leaving organisms in partnership, since a symbiotic technology is not credited to share the same needs (and rights) as the human being to which it is joined. 2 http://cordis.europa.eu/fp7/ict/docs/ict-wp2013-10-7-2013-with-cover-issn.pdf.
