Leucine Supplementation In Cuprizone-Induced Oligodendrocyte Toxicity, Michael Ley Jan 2019

Leucine Supplementation In Cuprizone-Induced Oligodendrocyte Toxicity, Michael Ley

Williams Honors College, Honors Research Projects

Cuprizone is a copper chelator that induces demyelination in the central nervous system when fed to mice. This compound is thought to target Complex IV and disrupt mitochondrial metabolism leading to loss of myelin-producing oligodendrocytes. In this proposal, we further examine the chemical and toxicological properties of cuprizone. Immunofluorescence imaging and microarray data on MO3.13 cells treated with cuprizone revealed the possibility of alterations in lysosomal function, as well as mitochondrial disruption via mTOR and Electron Transport Chain (ETC) related pathways. Cell viability assays conducted suggest that addition of Branched-Chain Amino Acids, most commonly used from literature, leucine, can increase …


Relationship Of Sociodemographic Factors With Serum Levels Of Vitamin D In A Healthy Population Of Pakistan, Khalida Iqbal, Najmul Islam, Naseema Mehboobali, Ali Asghar, Saleem Perwaiz Iqbal, Mohammad Perwaiz Iqbal Jan 2019

Relationship Of Sociodemographic Factors With Serum Levels Of Vitamin D In A Healthy Population Of Pakistan, Khalida Iqbal, Najmul Islam, Naseema Mehboobali, Ali Asghar, Saleem Perwaiz Iqbal, Mohammad Perwaiz Iqbal

Department of Biological & Biomedical Sciences

High prevalence of vitamin D deficiency has been reported from Pakistan. Association of sociodemographic factors with vitamin D status has received little attention in this region. Therefore, we embarked on investigating the relationship of sociodemographic factors with vitamin D levels in a healthy Pakistani population. Venous blood from 226 healthy participants (age range 19-69 years) was collected and analyzed for serum concentrations of 25(OH) vitamin D [25(OH)D] and other related biomarkers. Demographic characteristics of the study participants were collected. Vitamin D deficiency (25(OH)D levels less than 20 ng/ml) was found to be 75% in this cohort. Gender, sunlight exposure and …


The Effects Of Eicosapentaenoic Acid (Epa) And Docosahexaenoic Acid (Dha) On Brown Adipogenesis In Stem Cell Culture, Darynne A. Dahlem, Yan Huang Jan 2019

The Effects Of Eicosapentaenoic Acid (Epa) And Docosahexaenoic Acid (Dha) On Brown Adipogenesis In Stem Cell Culture, Darynne A. Dahlem, Yan Huang

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are major maternal dietary supplements due to their positive benefits on neurological tissue growth during the first 12 weeks of gestation. Previous studies show that EPA and DHA inhibit muscle formation but promote adipogenesis. However, no research has addressed the question whether high intake of EPA and DHA affects brown fat development during gestation. The objective of this study was to measure the effect of EPA and DHA supplement on brown adipogenesis and potential pathways related to mitochondrial biosynthesis using fibroblasts as in vitro model. Using Oil-Red-O staining …

Solutions For Fermi Questions, September 2019: Question 1: Losing Weight, Question 2: Shampoo Bottles, Larry Weinstein Jan 2019

Solutions For Fermi Questions, September 2019: Question 1: Losing Weight, Question 2: Shampoo Bottles, Larry Weinstein

Physics Faculty Publications

How much weight would you lose climbing stairs every day (assuming that neither diet nor metabolism changes in response to the extra effort)? The California Assembly voted to ban single-use hotel shampoo bottles. Thus our 6000 tons of shampoo bottles amounts to 30 parts per million of our total trash. [Extracted from the article]
