Police discrimination among Black, Latina/x/o, and White adolescents: Examining frequency and relations to academic functioning.

Introduction: Concerns regarding police brutality and violence against people of color in the U.S. remain high in the current sociohistorical moment in which the recent murder of George Floyd by a police officer is highly salient.

Counterstory methodology in a university-high school collaboration to center and humanize Latina/o voices.

Educational environments can often feel hostile and inequitable for Latina/o students and teachers, with limited resources and support to humanize their experiences. Counterstorytelling methodologies can be used by students and teachers to center lived experiences, contest deficit narratives, and uncover community cultural wealth (CCW). Drawing on a CCW lens, situated in critical race theory and Latina/o critical theory, we examine a university-high school service learning collaboration in an urban setting that focused on educational equity and counterstorytelling (5 high school classes, 80 students, and 1 teacher; 1 university class, 29 undergraduates, 1 graduate student, and 1 university professor) using ethnographic observations and reflections.

Trypsiligase-Catalyzed Labeling of Proteins on Living Cells.

Fluorescent fusion proteins are powerful tools for studying biological processes in living cells, but universal application is limited due to the voluminous size of those tags, which might have an impact on the folding, localization or even the biological function of the target protein. The designed biocatalyst trypsiligase enables site-directed linkage of small-sized fluorescence dyes on the N terminus of integral target proteins located in the outer membrane of living cells through a stable native peptide bond. The function of the approach was tested by using the examples of covalent derivatization of the transmembrane proteins CD147 as well as the EGF receptor, both presented on human HeLa cells.

Reflections from novice youth participatory action researchers: Emphasis on critical gender perspectives.

Rooted in multiracial feminist theory, this research investigated the roles of adults engaged in youth participatory action research (YPAR) projects focused on developing critical perspectives of gender, power, and critical hope with the youth of color. Across 10 weeks, two novice adult facilitators documented ethnographic observations (i.e.

Repeated potassium iodide exposure during pregnancy impairs progeny's brain development.

Protracted radioiodine release may require repeated intake of potassium iodide (KI) to protect thyroid gland. It is well established that iodine excess inhibits transiently the thyroid function. As developing fetus depends on maternal thyroid hormones (TH) supply, more knowledge is needed about the plausible effects that repeated KI intake can cause in this sensitive population, especially that even subtle variation of maternal thyroid function may have persistent consequences on progeny brain processing.
