The Impact Of Index Based Livestock Insurance (Ibli) On Child Nutrition In Marsabit County, Kenya, Jackson Kadyampakeni May 2024

The Impact Of Index Based Livestock Insurance (Ibli) On Child Nutrition In Marsabit County, Kenya, Jackson Kadyampakeni

Master's Theses

The study uses six rounds of Index-Based Livestock Insurance (IBLI) panel surveys (2009 – 2015) for Northern Kenya’s Marsabit county to investigate the impact of IBLI on child nutrition and household food security. We employ Ordinary Least Squares (OLS) and Instrumental Variable (IV) regressions to account for potential endogeneity in IBLI uptake. The results indicate that while IBLI uptake significantly improves the intake of key nutrients such as Vitamin A, protein, iron, and fruits and vegetables, it does not translate into significant improvements in child nutrition status, as measured by Mid-Upper Arm Circumference (MUAC) z-scores. Significant negative effects of age …

Towards A New Role Of Mitochondrial Hydrogen Peroxide In Synaptic Function, Cliyahnelle Z. Alexander May 2024

Towards A New Role Of Mitochondrial Hydrogen Peroxide In Synaptic Function, Cliyahnelle Z. Alexander

Student Theses and Dissertations

Aerobic metabolism is known to generate damaging ROS, particularly hydrogen peroxide. Reactive oxygen species (ROS) are highly reactive molecules containing oxygen that have the potential to cause damage to cells and tissues in the body. ROS are highly reactive atoms or molecules that rapidly interact with other molecules within a cell. Intracellular accumulation can result in oxidative damage, dysfunction, and cell death. Due to the limitations of H2O2 (hydrogen peroxide) detectors, other impacts of ROS exposure may have been missed. HyPer7, a genetically encoded sensor, measures hydrogen peroxide emissions precisely and sensitively, even at sublethal levels, during …

Optogenetic Induction Of Mitochondrial Oxidative Stress As A Potential Model To Study Non-Hereditary Als, Samia Alam

Student Theses and Dissertations

Mitochondrial dysfunction is a common denominator of neurodegenerative diseases, including hereditary and non-hereditary Amyotrophic Lateral Sclerosis (ALS). Ten percent of ALS cases are hereditary while a majority are sporadic, with no known hereditary link. For effective therapeutic approaches to be developed, there is a need for development of a sporadic animal model to better understand disease mechanism. In previous work, our laboratory developed an animal model (known as mitokiller flies) to study sporadic cases of ALS. The work reported in this honors thesis focuses on the use of optogenetics and electrophysiology recording to study the formation of excessive hydrogen peroxide …

Biological Sciences Faculty Publications

The water-lily clade represents the second earliest-diverging branch of angiosperms. Most of its species belong to Nymphaeaceae, of which the “core Nymphaeaceae”—comprising the genera Euryale, Nymphaea and Victoria—is the most diverse clade. Despite previous molecular phylogenetic studies on the core Nymphaeaceae, various aspects of their evolutionary relationships have remained unresolved. The length-variable introns and intergenic spacers are known to contain most of the sequence variability within the water-lily plastomes. Despite the challenges with multiple sequence alignment, any new molecular phylogenetic investigation on the core Nymphaeaceae should focus on these noncoding plastome regions. For example, a new plastid phylogenomic study on …
