Research examining STEM fields has identified barriers for traditionally marginalized groups pursuing these fields including a lack of representation and adequate role models.
Grounded with Minority Stress Theory (MST), the current study examines if a lack of inclusivity in typical course materials could create minority stress for two distinct marginalized student groups: racial and ethnic minority students (REM), and gender and sexual minority students (GSM).
Students were presented several questionnaires to understand their perceived representation of similar others in typical course materials, along with measures examining typical stress responses including feelings of belonging and rumination.
Results indicate that traditionally marginalized groups perceive less representation in course materials, feel less belonging and comfort in academic spaces, and suffer from more rumination.
As demonstrated in this study, underrepresented minority (URM) students experience a disadvantage in education in terms of feelings of belonging and representation, which can lead to increased rumination.
In STEM fields, course materials need to include more representation for URM students to reduce the stress that can result from this lack of exemplars.
Background and aims: Diabetes is a leading cause of renal failure. High levels of oxidative stress and inflammation in patients with renal diabetes lead to various disorders and mortality. This study was performed to determine the effect of Nigella sativa (NS) supplementation on superoxide dismutase (SOD), malondialdehyde (MDA), total antioxidant capacity (TAC), high-sensitivity C-reactive protein (hs-CRP), glycosylated hemoglobin (HbA1c), fasting blood sugar (FBS), and insulin (INS) in patients with diabetes mellitus undergoing hemodialysis (HD).
Methods: In this randomized, double-blind, placebo-controlled clinical trial, a total of 46 diabetic HD patients were randomly divided into NS (n = 23) and placebo (n = 23) groups. NS group received 2 g/day of NS oil, and the placebo group received paraffin oil for 12 weeks. Serum levels of SOD, MDA, TAC, hs-CRP, HbA1C, FBS, and INS were measured before and after the study.
Results: Compared to baseline values, SOD, TAC, and INS levels increased, whereas MDA, hs-CRP, HbA1c, and FBS significantly decreased. After adjusting for covariates using the ANCOVA test, changes in the concentrations of SOD (p = .040), MDA (p = .025), TAC (p=<.001), hs-CRP (p = .017), HbA1c (p = .014), and FBS (p = .027) were statistically significant compared to the placebo group. Intergroup changes in INS were not significant. Additionally, there were no notable side effects during the research.
Conclusions: This study found that NS supplementation significantly enhanced the levels of SOD, MDA, TAC, hs-CRP, HbA1c, and FBS in diabetic HD patients.
