What impacts have administrative support systems had on teaching and teaching retention in the post pandemic world?
No full textJulie Light, Bachelor of science in biology & Dr. Reinhardt, EDUC 5358What is Administrative Support? According to Boyd, et al, administrative support is defined as the effort that administrative staff, such as principles and other school leaders, take to help teachers with workloads and improving their lessons and teaching methods (Boyd, et al, 2011). Administrative support can look differently in schools. Examples include Professional development opportunities, Providing supplies for classrooms, Helping with classroom behavior management, Helping with excess wor

Bioactive ingredients in K. pinnata extract and the effects of combined K. pinnata and metformin preparations on antioxidant activities in diabetic and non-diabetic skeletal muscle cells
Get PDFWith healthcare costs rising, many affected by ailments are turning to alternative medicine for treatment. More people are choosing to complement their pharmacological regimen with dietary supplements from natural products. In this study, the compound composition of Kalanchoe Pinnata (K. pinnata) and the effects of combined preparations of K. pinnata and metformin on antioxidant activity in human skeletal muscle myoblasts (HSMMs) and human diabetic skeletal muscle myoblasts (DHSMMs) were investigated. Ultraperformance liquid chromatography fusion orbitrap mass spectrometry (UPLC-OT-FTMS) identified biologically active flavanols in K. pinnata. The main compounds identified in locally grown K. pinnata were quercetin, kaempferol, apigenin, epigallocatechin gallate (EGCG), and avicularin. Antioxidant results indicated that a combinatorial preparation of K. pinnata with metformin may modulate antioxidant responses by increasing the enzymatic activity of superoxide dismutase and increasing levels of reduced glutathione. A combination of 50 µM and 150 µg/mL of metformin and K. pinnata, respectively, resulted in a significant increase in reduced glutathione levels in non-diabetic and diabetic human skeletal muscle myoblasts and H2O2-stress-induced human skeletal muscle myoblasts. Additionally, a K. pinnata treatment (400 µg/mL) alone significantly increased catalase (CAT) activity for non-diabetic and diabetic human skeletal muscle myoblasts and a H2O2-stress-induced human skeletal muscle myoblast cell line, while significantly lowering malondialdehyde (MDA) levels. However, the treatment options were more effective at promoting cell viability after 24 h versus 72 h and did not promote cell viability after 72 h in H2O2 -stress induced HSMM cells. These treatment options show promise for treating oxidative-stress-mediated pathophysiological complications associated with type II diabetes.This study was supported by the Grants-In-Aid of Chemistry Graduate Research Program funded by the Welch Foundation (2018–2019) to P.R.
