Stigma Behavior

Background: Black adults are often seen as homogeneous despite the diversity within the Black population across ethnicity. Understanding the heterogeneity within the Black population will help address mental health disparities. Methods: A cross-sectional descriptive study and analysis was conducted among Black adults in the United States (n = 269, ages 18-65) from diverse ethnic backgrounds (African-Americans, African immigrants, Afro-Caribbean immigrants). We calculated mean differences according to ethnicity, citizenship status, age group, and gender in the areas of medical mistrust, use of mental health services, depression symptom severity, mental health knowledge and stigma behavior. Results: African Americans with moderate to severe depression symptoms had greater stigma behavior (mean = 12.2, SD = 3.2), than African Americans who screened in the minimal to mild depression range (mean = 13.1, SD = 3.5). Black immigrants across the spectrum of depression scores had greater stigma than African Americans (p = 0.037). Participants who identified as male had a prevalence of mild depression (5-9) that was 1.7 times higher than those who identified as female. Whereas, those who identified as female had a prevalence that was 1.2 times higher for moderate to severe depression (10-19) and 4.7 times higher for severe depression (20-27) compared to males (p = 0.021). Non-United States citizens reported higher medical mistrust (mean value difference = 0.16) compared to United States citizens (p = 0.011). Conclusion: This study shows key variations across social determinant of mental health factors among Black adults.

Mimulus Aurantiacus

The aim of this study is to give information on ultrastructure of in vivo pollen tubes of Mimulus aurantiacus which were collected from the Botanical Garden of the University of California at Berkeley. Materials were prepared according to electron microscopy methods and examined under Zeiss electron microscope. Four zones were examined in the pollen tubes of Mimulus aurantiacus. APICAL ZONE: Mitochondria, smooth endoplasmic reticulum, rough endoplasmic reticulum, dictyosomes and secretory vesicles were observed. SUBAPICAL ZONE: This area contained abundant rough endoplasmic reticulum and occasionally some smooth endoplasmic reticulum. The polysomes, mitochondria, proplastids that contain starch, small vacuoles and a few lipid bodies were detected. NUCLEAR ZONE: Both generative and vegetative cell nuclei lie in this zone. The vegetative cell nucleus was large and long. Rough endoplasmic reticulum, mitochondria, ribosomes, dictyosomes, and amyloplasts that are rich of starch were observed. VACUOLATION AND PLUG FORMATION ZONE: Cytoplasm of the tubes was full of large vacuoles. Few organelles such as mitochondria, dictyosome and rough endoplasmic reticulum were detected along their periphery.
