Scant Evidence for Long-Range Atmospheric Transport of Particle-Bound Benzotriazole Ultraviolet Stabilizers.

Environ Sci Technol

January 2025

Department of Physical and Environmental Sciences, University of Toronto Scarborough, 1265 Military Trail, Toronto, Ontario, Canada M1C 1A4.

Despite benzotriazole UV stabilizers (BT-UVs) being widely used since the 1960s, few empirical data on their atmospheric presence exist. UV-328 was added to the Stockholm Convention on Persistent Organic Pollutants, based in part on model calculations indicating atmospheric long-range transport potential. We investigated the atmospheric occurrence of BT-UVs at multiple sites that differ greatly in their proximity to potential sources.

Understanding how epithelial cells in the female reproductive tract (FRT) differentiate is crucial for reproductive health, yet the underlying mechanisms remain poorly defined. At birth, FRT epithelium is highly malleable, allowing differentiation into various epithelial types, but the regulatory pathways guiding these early cell fate decisions are unclear. Here, we use neonatal mouse endometrial organoids and assembloid coculture models to investigate how innate cellular plasticity and external mesenchymal signals influence epithelial differentiation.

Relationships between parasites, host physiology, and behaviours are complex. Parasites can influence host hormonal microenvironment and behaviour through "sickness behaviours" that generally conserve energy. Using a parasite removal experiment, we examined the effects of gastrointestinal parasites on fecal glucocorticoid metabolites (fGC) and behaviours of vervet monkeys (Chlorocebus pygerythrus) at Lake Nabugabo, Uganda.

Type 4 pili (T4P) are multifunctional filaments involved in adhesion, surface motility, biofilm formation, and horizontal gene transfer. These extracellular polymers are surface-exposed and, therefore, act as antigens. The human pathogen Neisseria gonorrhoeae uses pilin antigenic variation to escape immune surveillance, yet it is unclear how antigenic variation impacts most other functions of T4P.

Department of Medical Imaging, The Ottawa Hospital, 501 Smyth Rd, Ottawa, ON, Canada K1H 8L6 (D.V.F., J.L.); Department of Radiology, Radiation Oncology and Medical Physics, Faculty of Medicine, University of Ottawa, Ottawa, Ontario, Canada (D.V.F., J.L.); Ottawa Hospital Research Institute, Ottawa, Ontario, Canada (D.V.F., J.L.); and Department of Radiology, St. Paul's Hospital, University of British Columbia, Vancouver, British Columbia, Canada (T.M.).

Formerly termed or , core muscle injury (CMI) encompasses abnormality of structures within the so-called core, which is essentially the hip, abdomen, and pubis. Compared with data on image-guided procedures of other joints, information regarding procedures performed to address CMI and other disorders of the pubic symphysis is lacking. These procedures can be daunting given the joint's small size, surrounding critical neurovascular structures, and three-dimensional anatomy.

Psychology and whiteness itself.

Am Psychol

January 2025

Department of Counseling and Clinical Psychology, Teachers College, Columbia University.

In the aftermath of its Apology to People of Color (American Psychological Association, 2021b), the American Psychological Association recently committed itself to a long-term process by which it aims to address racial equity within the field of psychology as well as society more broadly (Andoh, 2022). In service of these ends, what can psychology learn from an analysis of the discursive framework within which it conducts its racism-related work? This critical conceptual article begins with the premise that all professional discourse-the concepts, language, and logic structures by which a field creates and communicates knowledge-inevitably bears the markings of the society in which it was established. Examination of psychological discourse, therefore, can reveal information not only about social hierarchies but also about the field's potential reproduction of them (even when the field intends to do otherwise).
