We report the first documented mixed outbreak of B. pertussis and B. holmesii infections. Bordetella holmesii particularly affected adolescents. Although laboratory capacity limitations might inhibit routine use of multitarget PCR for clinical diagnosis, focused testing and enhanced surveillance might improve understanding the burden of B. holmesii infection.
Lesbian subcultures have been described to downplay the importance of physical attractiveness and to challenge culturally prescribed beauty ideals. Within this context, one might argue that lesbians should be more accepting of their bodies and less likely to engage in disordered eating, than would heterosexual women. The relationship between sexual orientation and body esteem has not been examined empirically yet. This study compared 30 lesbian undergraduates and 52 heterosexual undergraduates on measures of body esteem, self‐esteem, and disordered eating. Few group differences were found. Lesbian students reported lower self‐esteem, more ineffectiveness, more interpersonal distrust, and more difficulties in identifying their own emotions, than did heterosexual students. Body esteem was found to be related more closely with self‐esteem in lesbians, than in heterosexual students. These group differences may reflect the lesbian experience more than disturbances associated with disordered eating.
Exhumed eclogitic crust is rare and exposures that preserve both protoliths and altered domains are limited around the world. Nominally anhydrous Neoproterozoic anorthositic granulites exposed on the island of Holsnøy, in the Bergen Arcs in western Norway, preserve different stages of progressive prograde deformation, together with the corresponding fluid-assisted metamorphism, which record the conversion to eclogite during the Ordovician-Silurian Caledonian Orogeny. Four stages of deformation can be identified: (1) brittle deformation resulting in the formation of fractures and the generation of pseudotachylites in the granulite; (2) development of mesoscale shear zones associated with increased fluid-rock interaction; (3) the complete large-scale replacement of granulite by hydrous eclogite with blocks of granulite sitting in an eclogitic "matrix"; and (4) the break-up of completely eclogitized granulite by continued fluid influx, resulting in the formation of coarse-grained phengite-dominated mineral assemblages. P-T constraints derived from phase equilibria forward modelling of mineral assemblages of the early and later stages of the conversion to eclogite document burial and partial exhumation path with peak metamorphic conditions of~21-22 kbar and 670-690°C. The P-T models, in combination with existing T-t constraints, imply that the Lind as Nappe underwent extremely rapid retrogressive pressure change. Fluid infiltration began on the prograde burial path and continued throughout the recorded P-T evolution, implying a fluid source that underwent progressive dehydration during subduction of the granulites. However, in places limited fluid availability on the prograde path resulted in assemblages largely consuming the available fluid, essentially freezing in snapshots of the prograde evolution. These were carried metastably deeper into the mantle with strain and metamorphic recrystallization partitioned into areas where ongoing fluid infiltration was concentrated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
