A Synergistic Anti-Diabetic Effect By Ginsenosides Rb1 And Rg3 Through Adipogenic And Insulin Signaling Pathways In 3t3-L1 Cells, Hee-Do Hong, Sun-Il Choi, Ok-Hwan Lee, Young-Cheul Kim

Nutrition Department Faculty Publication Series

Although ginsenosides Rb1 and Rg3 have been identified as the significant ginsenosides found in red ginseng that confer anti-diabetic actions, it is unclear whether insulin-sensitizing effects are mediated by the individual compounds or by their combination. To determine the effect of ginsenosides Rb1 and Rg3 on adipocyte differentiation, 3T3-L1 preadipocytes were induced to differentiate the standard hormonal inducers in the absence or presence of ginsenosides Rb1 or Rg3. Additionally, we determined the effects of Rb1, Rg3, or their combination on the expression of genes related to adipocyte differentiation, adipogenic transcription factors, and the insulin signaling pathway in 3T3-L1 cells using …

Evaluation Report, Alan Peterfreund

STEM Digital

This evaluation report synthesizes the results of evaluation activities conducted by SageFox Consulting Group of the STEM DIGITAL project led by the UMass STEM Ed Institute for its no-cost extension year, covering the period September 2013 to August 2014. The goals of the program are to facilitate the participants’ abilities to stimulate student interest in STEM careers while engaging them in ways to think critically about their environment. Participating teachers incorporated digital cameras and Analyzing Digital Images (ADI) software into lab activities focusing on environmental science. STEM DIGITAL materials focused on three strands related to (1) ozone and air quality, …

Measuring The Acceleration Of Falling Objects, John Pickle

STEM Digital

Earth's gravity pulls all objects toward its center, and near the Earth's surface. Objects in free fall accelerate at 9.8 m/s² vertically downward, provided air resistance is negligible. This value of acceleration is often referred to as "g". There are many ways to measure this rate of acceleration, and most require a timing device. Typically, stopwatches are the least expensive technology, so these are commonly available in high school science classrooms. With the recent addition of movie cameras on cell phones and digital cameras, another timing tool is available at moderate cost (free if the school policy …

•The water industry spends a lot of money and effort on removal of natural organic matter (NOM) from drinking waters •Problems with NOM (the more NOM the bigger problem) –NOM interferes with the ability of water treatment systems to remove substances that cause disease •Pathogenic organisms •Toxic chemicals –NOM reacts with chlorine‐based disinfectants forming carcinogenic organic byproducts
