Black Emotions Matter: Understanding the Impact of Racial Oppression on Black Youth's Emotional Development: Dismantling Systems of Racism and Oppression During Adolescence: Dismantling Systems of Racism and Oppression During Adolescence.

Black US Americans' emotions are subject to stereotypes about the anger and aggression of Black people. These stereotypes are readily applied to Black adolescents' emotions. The purpose of this conceptual paper is to operationalize racial oppression in the emotional lives of Black adolescents through an application of García Coll et al.'s (1996) ecological model for minority youth development. We specify emotionally inhibitive features of Black adolescents' schools, the adaptive culture of Black Americans in the United States that responds to emotional inhibition, Black families' emotion socialization processes, and Black adolescents' emotional flexibility behaviors. Throughout, we integrate findings from research on Black adolescents' emotional adjustment with research on cultural values, emotion and racial socialization, school-based racial experiences, and theory on emotion and cultural navigation.

Paternal biopsychosocial resilience in triadic interactions among African American/Black families exposed to trauma and socioeconomic adversity.

Fathers have a distinct and unique effect on child development, but little is known about fathering beyond White or majority White families. The current study includes African American/Black biological fathers (N = 88) and their two-year-old children. Fathers reported low incomes and high rates of depression and posttraumatic stress disorder (PTSD). Parenting behaviors were observed in high-stress and low-stress triadic contexts. In the high-stress condition, we assessed paternal responses to children's bids after the family was reunited following a separation paradigm. In the low-stress condition, we assessed parenting behaviors during a teaching task. Fathers' social baseline respiratory sinus arrhythmia (RSA) was obtained as an index of parasympathetic arousal. RSA moderated the association between PTSD and fathers' responsiveness (F = 6.90, p = .00, R2  = .30), with no association between PTSD and responsiveness demonstrated among fathers with the highest levels of RSA relative to the sample (effect = .04, p = .00; CI [0.02, 0.06]). RSA did not moderate the association between paternal depression and parenting behaviors (p > .05). Furthermore, responsiveness was only significantly associated with low-stress paternal teaching behaviors for fathers with lower RSA (F = 4.34, p = .01, R2  = .21; effect = -.19, p = .00; CI [0.06, 0.32]). Findings demonstrate significant relationships among RSA, PTSD, and parenting for African American/Black men in contexts of economic adversity.

The associations between African American emerging adults' racial discrimination and civic engagement via emotion regulation.

OBJECTIVE: The current study tested direct and indirect associations between racial discrimination and civic engagement via emotion regulation strategies. Differences between males and females were also explored. METHOD: African American college students (76% female; Mage = 18.42) participating in a university-wide research study provided self-reports of their racial discrimination experiences, use of emotion regulation strategies, and civic engagement attitudes and beliefs. RESULTS: Greater racial discrimination was associated with less use of reappraisal (i.e., thinking about emotions in a different way) and, in turn, use of reappraisal was associated with greater civic engagement attitudes. The same association was found for civic engagement behaviors. However, reappraisal was associated with greater civic engagement behaviors for females and less civic engagement behaviors for males. CONCLUSION: The current study highlights the need to consider the role of cognitive emotion regulation strategies on college students' sociopolitical development and civic engagement.

Effect of oral contraceptives on the transport of chlorpromazine across the CACO-2 intestinal epithelial cell line.

In previous chlorpromazine pharmacokinetic studies a dramatic elevation in blood plasma levels of this drug was observed when taken in combination with oral contraceptives. Different mechanisms have been postulated to explain this observation. The aim of the study was to investigate whether oral contraceptives such as ethinyloestradiol and progesterone enhance the absorption of chlorpromazine by means of inhibiting P-glycoprotein (P-gp) and if this effect is mainly due to ethinyloestradiol or progesterone or their combination. The Caco-2 cell line was used as an in vitro model to study the effects of these compounds on the transport of chlorpromazine. Both apical to basolateral (AP-BL) and basolateral to apical (BL-AP) transport studies were done on chlorpromazine in combination with different compounds. Ethinyloestradiol enhanced the AP-BL cumulative transport of chlorpromazine by 11.5% compared to the control group, which was also statistically significantly higher than the effect caused by progesterone (0.8%). A combination of these two steroidal hormones enhanced the cumulative transport of chlorpromazine by only 2.0% compared to the control group. This indicates the possible existence of separate drug-binding sites for these two hormones and chlorpromazine on P-gp. The drug-binding site (or receptor) for progesterone probably interacts allosterically with the binding site for ethinyloestradiol and thereby decreasing its transport enhancing effects on chlorpromazine.
