DOI: 10.1007/s00216-019-02295-y
Abstract: 4,4′-Methylenediphenyldiisocyanate (MDI), toluenediisocyanate (2,4-TDI and 2,6-TDI), and 1,6′-hexamethylenediisocyanate (HDI) are all commonly used in the production of polyurethane-containing materials in different application areas. Workers exposed occupationally to these compounds may develop sensitization with the potential… read more here.

Length of time domestic dogs (Canis familiaris) spend smelling urine of gonadectomised and intact conspecifics
Sign Up to like & getrecommendations! Published in 2017 at "Behavioural Processes"
DOI: 10.1016/j.beproc.2017.06.009
Abstract: Domestic dogs (Canis familiaris) use urine to communicate among themselves, however, it is unknown whether the gonadectomy (neutering or spaying) of a dog affects this communication in anyway. Urine samples from 10 intact and 10… read more here.
