Rumen Microorganisms Decrease Bioavailability of Inorganic Selenium Supplements

Creator:: Galbraith, M. L., Vorachek, W. R., Estill, C. T., Whanger, P. D., Bobe, G., Davis, T. Z., and Hall, J. A.
Abstract:: Despite the availability of selenium (Se)-enriched trace mineral supplements, we have observed low Se status in cattle and sheep offered traditional inorganic Se supplements. Reasons for this may include inadequate intake or low bioavailability of inorganic Se sources. The objective of this study was to determine whether rumen microorganisms (RMO)...

Effect of Testosterone on Neuronal Morphology and Neuritic Growth of Fetal Lamb Hypothalamus-Preoptic Area and Cerebral Cortex in Primary Culture

Creator:: Reddy, Radhika C., Amodei, Rebecka, Estill, Charles T., Stormshak, Fred, Meaker, Mary, and Roselli, Charles E.
Abstract:: Testosterone plays an essential role in sexual differentiation of the male sheep brain. The ovine sexually dimorphic nucleus (oSDN), is 2 to 3 times larger in males than in females, and this sex difference is under the control of testosterone. The effect of testosterone on oSDN volume may result from...

Flaxseed supplementation decreases methanogenic gene abundance in the rumen of dairy cows

Creator:: Li, L., Schoenhals, K. E., Brady, P. A., Estill, C. T., Perumbakkam, S., and Craig, A. M.
Abstract:: The objective of this study was to investigate the effects of a flaxseed-supplemented diet on archaeal abundance and gene expression of methanogens in the rumen of dairy cows. In all, 11 non-lactating dairy cows were randomly divided into two groups: group A (five cows) and B (six cows). The two...

Prenatal Influence of an Androgen Agonist and Antagonist on the Differentiation of the Ovine Sexually Dimorphic Nucleus in Male and Female Lamb Fetuses

Creator:: Roselli, Charles E., Reddy, Radhika C., Estill, Charles T., Scheldrup, Melissa, Meaker, Mary, Stormshak, Fred, and Montilla, Hernán J.
Abstract:: The ovine sexually dimorphic nucleus (oSDN) is 2 times larger in rams than in ewes. Sexual differentiation of the oSDN is produced by testosterone exposure during the critical period occurring between gestational day (GD)60 and GD90 (term, 147 d). We tested the hypothesis that testosterone acts through the androgen receptor...

Teaching About Disability in Psychology: An Analysis of Disability Curricula in U.S. Undergraduate Psychology Programs

Creator:: Rosa, Nicole M., Bogart, Kathleen R., Bonnett, Amy K., Estill, Mariah C., and Colton, Cassandra E.
Abstract:: Historically, Psychology education about disability focused narrowly on psychiatric and cognitive disabilities. Furthermore, disability tends to be viewed from the medical model, rather than the social model endorsed by disability scholars, which describes disability as primarily socially constructed. Course offerings for the Psychology departments of 98 top-ranked undergraduate programs in...

Bovine hepatic differential gene expression in response to perennial ryegrass staggers

Creator:: Li, L., Tanaree, D. D., Di, Y., Estill, C. T., Duringer, J. M., Blythe, L. L., Galen, A., Livesay, S., and Craig, A. M.
Abstract:: “Perennial ryegrass staggers” is a neurological condition characterized by muscular tremors and ataxia in livestock that ingest the indole diterpene lolitrem B from endophyte-infected perennial ryegrass. While the neurotoxic mechanism of action of ryegrass staggers has been defined, little is known about metabolic and other molecular processes that lolitrem B...

Effect of Feeding Selenium-Fertilized Alfalfa Hay on Performance of Weaned Beef Calves

Creator:: Hall, Jean A., Bobe, Gerd, Hunter, Janice K., Vorachek, William R., Stewart, Whitney C., Vanegas, Jorge A., Estill, Charles T., Mosher, Wayne D., and Pirelli, Gene J.
Abstract:: Selenium (Se) is an essential micronutrient in cattle, and Se-deficiency can affect morbidity and mortality. Calves may have greater Se requirements during periods of stress, such as during the transitional period between weaning and movement to a feedlot. Previously, we showed that feeding Se-fertilized forage increases whole-blood (WB) Se concentrations...

Phenology and Productivity of C₃ and C₄ Grasslands in Hawaii

Creator:: Pau, Stephanie and Still, Christopher J.
Abstract:: Grasslands account for a large proportion of global terrestrial productivity and play a critical role in carbon and water cycling. Within grasslands, photosynthetic pathway is an important functional trait yielding different rates of productivity along environmental gradients. Recently, C₃-C₄ sorting along spatial environmental gradients has been reassessed by controlling for...

Biogeographically distinct controls on C₃ and C₄ grass distributions: merging community and physiological ecology

Creator:: Griffith, Daniel M., Anderson, T. Michael, Osborne, Colin P., Strömberg, Caroline A. E., Forrestel, Elisabeth J., and Still, Christopher J.
Abstract:: AIM: C₄ photosynthesis is an adaptation that maintains efficient carbon assimilation in warm and low-CO₂ conditions. Due to the importance of C₄ grasses for carbon and surface energy fluxes numerous models have been proposed to describe their spatial distribution and forecast responses to climate change. These models often rely on...

Continuous Flow Synthesis of Ceria Nanoparticles Using Static T-mixers

Creator:: Palanisamy, Barath and Paul, Brian
Abstract:: Ceria nanoparticles are of interest owing to their interesting properties like photo-absorption and ability to absorb oxygen. Several batch synthesis routes exist however these methods often lack particle size control, result in agglomeration and typically require high temperature processing. In this paper, a continuous flow microchannel synthesis method based on...
