The literature contains very little knowledge regarding the indoor well-being of people with autism spectrum conditions (ASC). Though, when dealing with higher autism levels and specific co-morbidities, the lack of autonomy of potential subjects makes standard comfort studies difficult or even impossible. As part of the EU-funded project “SENSEwellbeing”, the present paper shows the preliminary results of a field study on the indoor thermal and visual well-being of non-autonomous people with ASC, performed in a Danish care-center. Due to the fragility of the subjects involved and ethical issues related, we had to overcome several challenges. A determining example is the limited possibility to directly involve the subjects and make interventions in their private spaces in comfort-related experiments. For this reason, the caregivers working in the facility were involved in a semi-structured interview to indirectly characterize the thermal and visual preferences of subjects. Additionally, short- and long-term measurements of indoor quantities were taken in common rooms and empty living spaces. The interviews’ outcomes were linked to the environmental measurement, allowing a preliminary characterization of the adequacy of indoor design in terms of well-being of non-autonomous people with ASC. The study highlights the differences in perception of thermal and visual environment among people with ASC, and the necessity to find solutions to more directly involve non-autonomous subjects in studies on the indoor environment. The present research may also inspire other studies with people with special needs, whose comfort perception would otherwise be challenging to collect.

The cellular and molecular mechanisms regulating the reuptake of the testicular fluid supporting sperm exiting the testes in the bird are not known. The presence of aquaporins, proteins involved in transmembrane water transport, was investigated. Observations were limited to the ductuli efferentes, collecting ducts, and ductus epididymis. Interestingly all of these ducts were positive for aquaporins-2, -3, and -9 but not aquaporin- 7. When positive, aquaporin was observed localized over the whole cell or the apical plasma membrane of the nonciliated cells and the apical plasma membrane and cilia of the ciliated cells. This study is the first to clearly demonstrate the presence of aquaporins-2, -3, and - 9 in the epididymal region of any bird. We assume the aquaporins play a role in concentrating the sperm and in the promotion of sperm maturation in the epididymal region.

Oviductal sperm storage tubules (SST), located at the uterovaginal junction, are the primary site of sperm storage in turkeys. Sperm reside within these storage sites and may be released via a dynamic interaction between sperm mobility and a fluid current generated by the SST epithelial cells. In this study, aquaporins 2, 3, and 9 (proteins that form water channels in the plasmalemma of a variety of cells) were immunocytochemically localized within the apical aspect of the epithelial cells that form the SST. These observations support the contention that the SST epithelial cells are capable of water exchange that may interact with sperm residing within the SST.
