Birth Control Behind Bars: An Anthropological Perspective On The Care Of Captive Bonobos, Tylyn A. Recore-Dagsaan

PANDION: The Osprey Journal of Research and Ideas

Bonobos are one of our closest living primate relatives. They are primarily known for their unique social structure and sexual behavior. In their native setting, the Democratic Republic of the Congo, bonobos are often seen engaging in sexual behaviors not only for reproduction, but for social reasons too. Unfortunately, research in the wild is difficult because of political unrest and rapidly declining population numbers. Since bonobos are endangered, it is crucial that we maintain and properly care for a captive population to ensure the survival of the species. A captive setting provides a safe, controlled environment for researchers to observe …

Engineered Extracellular Vesicles Loaded With Mir-124 Attenuate Cocaine-Mediated Activation Of Microglia, Ernest T. Chivero, Ke Liao, Fang Niu, Ashutosh Tripathi, Changhai Tian, Shilpa Buch, Guoku Hu

Journal Articles: Pharmacology & Experimental Neuroscience

MicroRNA-124 (miR-124), a brain-enriched microRNA, is known to regulate microglial quiescence. Psychostimulants such as cocaine have been shown to activate microglia by downregulating miR-124, leading, in turn, to neuroinflammation. We thus rationalized that restoring the levels of miR-124 could function as a potential therapeutic approach for cocaine-mediated neuroinflammation. Delivering miRNA based drugs in the brain that are effective and less invasive, however, remains a major challenge in the field. Herein we engineered extracellular vesicles (EVs) and loaded them with miR-124 for delivery in the brain. Approach involved co-transfection of mouse dendritic cells with Dicer siRNA and RVG-Lamp2b plasmid to deplete …

Formal Language Constraints In Deep Reinforcement Learning For Self-Driving Vehicles, Tyler Bienhoff

School of Computing: Dissertations, Theses, and Student Research

In recent years, self-driving vehicles have become a holy grail technology that, once fully developed, could radically change the daily behaviors of people and enhance safety. The complexities of controlling a car in a constantly changing environment are too immense to directly program how the vehicle should behave in each specific scenario. Thus, a common technique when developing autonomous vehicles is to use reinforcement learning, where vehicles can be trained in simulated and real-world environments to make proper decisions in a wide variety of scenarios. Reinforcement learning models, however, have uncertainties in how the vehicle acts, especially in a previously …

Aryl hydrocarbon receptor (AHR) agonists such as dioxin have been associated with obesity and the development of diabetes. Whole-body Ahr knockout mice on high-fat diet (HFD) have been shown to resist obesity and hepatic steatosis. Tissue-specific knockout of Ahr in mature adipocytes via adiponectin-Cre exacerbates obesity while knockout in liver increases steatosis without having significant effects on obesity. Our previous studies demonstrated that treatment of subcutaneous preadipocytes with exogenous or endogenous AHR agonists disrupts maturation into functional adipocytes in vitro. Here, we used platelet-derived growth factor receptor alpha (Pdgfrα)-Cre mice, a Cre model previously established to knock out genes in …

Optimal Learning Rates For Neural Networks, Tyler Moncur

Theses and Dissertations

Neural networks have long been known as universal function approximators and have more recently been shown to be powerful and versatile in practice. But it can be extremely challenging to find the right set of parameters and hyperparameters. Model training is both expensive and difficult due to the large number of parameters and sensitivity to hyperparameters such as learning rate and architecture. Hyperparameter searches are notorious for requiring tremendous amounts of processing power and human resources. This thesis provides an analytic approach to estimating the optimal value of one of the key hyperparameters in neural networks, the learning rate. Where …

Biological Control Potential Of Streptomyces Isolates On Pathogens (Helminthosporium Solani And Pythium Ultimum) Of Potatoes, Shae Jamison Taylor

Theses and Dissertations

Two fungal pathogen species, Helminthosporium solani and Pythium ultimum, cause significant economic loss to potato (Solanum tuberosum) growers throughout the world. These pathogens have substantial differences in cellular makeup, pathogenicity, and modes of infection. We studied the efficacy of 82 isolates within the bacterial genus Streptomyces in inhibiting these pathogens under laboratory and greenhouse conditions. Derivatives of Streptomyces have significant implications in medicinal use because of their antibiotic and antifungal properties. Under in-vitro conditions, 25% of Streptomyces isolates inhibited growth of P. ultimum, up to 81%. Ninety-five percent of the Streptomyces isolates inhibited growth of H. solani, with a maximum …

Children’s Nutrition Research Center Staff Publications

Defective rhythmic metabolism is associated with high-fat high-caloric diet (HFD) feeding, ageing and obesity; however, the neural basis underlying HFD effects on diurnal metabolism remains elusive. Here we show that deletion of BMAL1, a core clock gene, in paraventricular hypothalamic (PVH) neurons reduces diurnal rhythmicity in metabolism, causes obesity and diminishes PVH neuron activation in response to fast-refeeding. Animal models mimicking deficiency in PVH neuron responsiveness, achieved through clamping PVH neuron activity at high or low levels, both show obesity and reduced diurnal rhythmicity in metabolism. Interestingly, the PVH exhibits BMAL1-controlled rhythmic expression of GABA-A receptor γ2 subunit, and dampening …
