Understanding the variables that affect the anaerobic potentially mineralizable N (PMNan) test should lead to a standard procedure of sample collection and incubation length, improving PMNan as a tool in corn (Zea mays L.) N management. We evaluated the effect of soil sample timing (preplant and V5 corn development stage [V5]), N fertilization (0 and 180 kg ha−1) and incubation length (7, 14, and 28 d) on PMNan (0–30 cm) across a range of soil properties and weather conditions. Soil sample timing, N fertilization, and incubation length affected PMNan differently based on soil and weather conditions. Preplant vs. V5 PMNan …

Evaluation Of Anterior Pituitary Leptin Receptor Expression In Pregnant And Non-Pregnant Gilts, Juliana Pederson, Jeffrey Clapper

Schultz-Werth Award Papers

Successful reproduction in porcine depends on the coordinated synthesis and release of several hormones from the hypothalamus and anterior pituitary gland. Leptin, a hormone produced from adipocytes, interacts with other specific reproductive hormones and affects the reproductive success in swine. However, the full extent of leptin’s impact is unclear. This experiment sought to examine the difference in expression between the anterior pituitary gland leptin receptors in pregnant and non-pregnant pigs to confer the impact leptin has on reproductive success. Twentyfour crossbred gilts of similar age and weight had their estrus cycles synchronized and then were bred via artificial insemination. The …

How Exercise Impacts The Brain And Cognition, Cody Larson

Biology and Microbiology Graduate Students Plan B Research Projects

Physical exercise has been shown to impact the brains composition and functionality. The changes that arise in the structure of brain, as result of engaging in physical exercise, give rise to cognitive changes. Structural changes are observed most notably in the prefrontal cortex and hippocampus. These changes are preceded by elevations in cerebral blood flow, and growth factors, resulting increased neuroplasticity and neurogenesis. Frequency, duration, intensity, and type of physical exercise can have differing effects on the brain. Moderate intensity aerobic exercise presents the most profound improvements in memory, and inhibitory control over time.

Epigenetic Modifications Due To Maternal Diet, Amanda Thaler

Biology and Microbiology Graduate Students Plan B Research Projects

Obesity is a growing exponentially to be a health issue globally. Worldwide the rate of obesity has nearly doubled since 1980, with approximately 200 million adult men and 300 million adult women now being considered obese. We are also seeing growing percentages of woman of reproductive age being considered obese (BMI>30). Maternal obesity is known to increase the likelihood of developing complications during the pregnancy such as gestational diabetes and pre-eclampsia. These conditions create the environment for the growing fetus that are more difficult than that of a healthy pregnancy. The Developmental programming hypotheses links the environment of development …

The studies were established near Brookings, SD and Beresford, SD. In-season treatments were targeting nutrient availability or protecting soybean canopy during the grain filling period. Such treatments included the use of fungicide, insecticide, or supplying …

Mechanistic Studies To Understand The Role Of Human Gut Microbiota In Colonization Resistance And Gut Health, Sudeep Ghimire

Electronic Theses and Dissertations

Human gut microbiota is comprised of thousands of species which fall into two major categories or “enterotypes” based on dominating bacteria: “Bacteroides” and “Prevotella”. Bacteroides enterotype dominates the microbiota of the western population because of a high protein and fat diet, whereas Prevotella enterotype is dominate in the gut of the eastern population because of a high carbohydrate diet. While most of the microbiota studies focused on the Bacteroides enterotype using both metagenomics and culturomics, Prevotella enterotype is understudied, especially in the field of culturomics. The structure of the Prevotella dominated gut microbiome is revealed by …
