A population of cows with excess androstenedione (A4; High A4) in follicular fluid, with follicular arrest, granulosa cell dysfunction, and a 17% reduction in calving rate was previously identified. We hypothesized that excess A4 in the ovarian microenvironment caused the follicular arrest in High A4 cows and that vascular endothelial growth factor A would rescue the High A4 phenotype. In trial 1, prior to culture, High A4 ovarian cortex (n=9) had greater numbers of early stage follicles (primordial) and fewer later-stage follicles compared to controls (n=11). Culture for 7 days did not relieve this follicular arrest; …

High Rates Of Polygyny In Tropical Mexico Within The Native Range Of Vespula Squamosa., Alex K. Snyder, Kevin J. Loope

Honors College Theses

Polygyny, or the formation of colonies with multiple cooperating queens, has been observed in a variety of social Hymenoptera and likely exists as a convergent evolutionary strategy. Polygyne cooperation has been observed in several Vespula sp. and is correlated with a perennial social strategy. This perennial-polygyne behavior has been observed most commonly within the tropical and subtropical regions of the invasive Vespula pensylvanica and V. germanica, and rarely within their native temperate ranges. This phenomenon has been relatively undocumented within the tropical portions the V. squamosa native range, despite it being observed in their temperate ranges several times. We observed …

Prevalence Of Trypanosome Species In Cattle Near Ruma National Park, Lambwe Valley, Kenya: An Update From The Historical Focus For African Trypanosomosis, Shewit Kalayou, Michael Nyang Anga Okal, Peter Otieno Odhiambo, Kawira Mathenge, Daniel Ochieng Gamba, Edward Kariuki, Francis Mcodimba, Daniel Masiga

All Peer-Reviewed Publications

The effective control of diseases in areas shared with wildlife depends on the validity of the epidemiologic parameters that guide interventions. Epidemiologic data on animal trypanosomosis in Lambwe valley are decades old, and the recent suspected outbreaks of the disease in the valley necessitate the urgent bridging of this data gap. This cross-sectional study estimated the prevalence of bovine trypanosomosis, identified risk factors, and investigated the occurrence of species with zoonotic potential in Lambwe valley. The area is ~324 km2, of which 120 km2 is the Ruma National Park. Blood was sampled from the jugular and marginal ear veins of …

A Class Ii Mhc-Targeted Vaccine Elicits Immunity Against Sars-Cov-2 And Its Variants, Novalia Pishesha, Paul W Rothlauf, Mariel J Liebeskind, Maria A Vakaki, Louis-Marie Bloyet, Marjorie Cornejo Pontelli, Ma Xenia G Ilagan, William J Buchser, Sean P J Whelan, Et Al

Open Access Publications

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in over 100 million infections and millions of deaths. Effective vaccines remain the best hope of curtailing SARS-CoV-2 transmission, morbidity, and mortality. The vaccines in current use require cold storage and sophisticated manufacturing capacity, which complicates their distribution, especially in less developed countries. We report the development of a candidate SARS-CoV-2 vaccine that is purely protein based and directly targets antigen-presenting cells. It consists of the SARS-CoV-2 Spike receptor-binding domain (Spike

The gastric epithelium is often exposed to injurious elements and failure of appropriate healing predisposes to ulcers, hemorrhage, and ultimately cancer. We examined the gastric function of CD36, a protein linked to disease and homeostasis. We used the tamoxifen model of gastric injury in mice null for Cd36 (Cd36

Mirna-30e Downregulation Increases Cancer Cell Proliferation, Invasion And Tumor Growth Through Targeting Rps6kb1, Lin Wang, Xiang-Bo Ji, Li-Hong Wang, Zhong-Kun Xia, Yun-Xia Xie, Wen-Jing Liu, Jian-Ge Qiu, Bing-Hua Jiang, Ling-Zhi Liu

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Human esophagus carcinoma (EC) is one of the most common malignant tumors, especially in Africa and Asia including China. In EC initiation and progression, genetic and epigenetic aberrations have been reported to play a major role, but the underlying molecular mechanisms are largely unknown. In this study, the miR-30e levels were analyzed in human EC tissues and TCGA databases, and the results demonstrated that miR-30e expression in EC tissues was significantly decreased compared to adjacent normal tissues. To further investigate the role of miR-30e in cancer cells, we found that forced expression of miR-30e dramatically inhibited cell proliferation, invasion, tube …

Excitotoxic Lesions Of The Perirhinal Cortex Leave Intact Rats’ Gustatory Sensory Preconditioning, Jasper Robinson, Peter M. Jones, Emma J. Whitt

School of Psychology

We report findings from two sensory preconditioning experiments in which rats consumed two flavoured solutions, each with two gustatory components (AX and BY), composed of sweet, bitter, salt, and acid elements. After this pre-exposure, rats were conditioned to X by pairing with lithium chloride. Standard sensory preconditioning was observed: Consumption of flavour A was less than that of B. We found that sensory preconditioning was maintained when X was added to A and B. Both experiments included one group of rats with lesions of the perirhinal cortex, which did not influence sensory preconditioning. We discuss our findings in the light …

2020-Current year OA Pubs

Alcohol and other substance use disorders share comorbidity with other RDS disorders, i.e., a reduction in dopamine signaling within the reward pathway. RDS is a term that connects addictive, obsessive, compulsive, and impulsive behavioral disorders. An estimated 2 million individuals in the United States have opioid use disorder related to prescription opioids. It is estimated that the overall cost of the illegal and legally prescribed opioid crisis exceeds one trillion dollars. Opioid Replacement Therapy is the most common treatment for addictions and other RDS disorders. Even after repeated relapses, patients are repeatedly prescribed the same opioid replacement treatments. A recent …

Consumers' Perception Of Food Containing Insect Protein Affected By Serving Condition And Questionnaire Protocol, Yupeng Gao

LSU Master's Theses

Edible insects are a new sustainable protein source compared to meat. Western consumers show aversion to the prospect of insects as food due to unfamiliarity, food neophobia, and negative emotions. This dissertation research explored consumers’ emotional perception of insect-based food products presented under different testing conditions and examined the influence of other people’s emotional expressions towards consumers’ purchase decisions. To identify and rate emotion intensities, tests were conducted using three presenting formats including text, image, and an actual product; all of which were applied for both cookies containing insects and without insects. In addition to these presenting formats, news of …

The Puzzling Presence Of Lestes Australis (Odonata: Lestidae) In Wisconsin - Does This Species Migrate?, Robert B. Dubois, Kenneth J. Tennessen

The Great Lakes Entomologist

Lestes disjunctus australis Walker, 1952 was named as a subspecies of Lestes disjunctus Selys, 1862. In recent decades it has been considered deserving of full species status by most specialists. The core of its eastern North American range is south of Wisconsin, but during April through June of some years, mature individuals, and occasionally reproductive behavior, are observed at shallow ponds and wetlands mostly in the southern half of the state. Since first recorded in Wisconsin in 2002, it has been detected in 13 of Wisconsin’s 72 counties. However, there has been no unequivocal documentation of successful reproduction in the …

Bark- And Wood-Infesting Insects (Coleoptera And Hymenoptera) And Associated Parasitoids Reared From Yellow Birch (Betula Alleghaniensis) In Ingham County, Michigan, Robert A. Haack

The Great Lakes Entomologist

Four species of bark- and wood-infesting borers (two Coleoptera and two Hymenoptera) and six parasitoid species (Hymenoptera) were reared from yellow birch (Betula alleghaniensis Britton) one year after the trees were cut and left standing in a woodlot in Ingham County, Michigan in 1986–87. The borers were species of Cerambycidae (Coleoptera) and Xiphydriidae (Hymenoptera), and hymenopteran parasitoid species of Aulacidae, Braconidae, Chalcididae, and Pteromalidae. Xiphydriophagus meyerinckii (Ratzeburg) (Pteromalidae) is a new Michigan state record. For the borers, yellow birch is a new host record for the cerambycid Sternidius alpha (Say) and the xiphydriid Xiphydria tibialis Say. Seasonal emergence data …

Agricultural Natural Enemies Benefit Predominantly From Broader Scales Of Environmental Heterogeneity: A Quantitative Review, Aaron Iverson, Robyn Burnham, John Vandermeer

The Great Lakes Entomologist

Naturally occurring predator and parasitoid communities are well known to respond to multiple scales of environmental heterogeneity within and around agroecoystems, yet our understanding of which scales are most influential on different functional guilds of enemies is limited. Using vote-counting methodology, we synthesized the results from 40 empirical studies that observed how natural enemy richness, diversity, or parasitism rate is affected by environmental heterogeneity at a local scale (e.g. a focal field), an intermediate scale (e.g. habitat in immediate proximity of a focal field), and landscape scale (e.g. habitat within >200 m radius around focal field). Heterogeneity at all scales …

Spiraling Flight Behavior May Integrate The Biological Compass Systems Of Migratory North American Monarch Butterflies, (Danaus Plexippus, L.), Matthew M. Douglas

The Great Lakes Entomologist

Here I report a unique spiraling flight and orientation behavior (comprising multiple clockwise and counterclockwise circles coupled by extended figure-8 patterns) observed in free-flying “late” migratory monarchs released under sunny ambient field conditions from a location with an unobstructed view of the sky. Following this spiraling flight, migrants continue to fly at very high altitudes until a final orientation and migratory flight direction is established with vanishing bearings statistically concentrated to the SW/W. These results provide preliminary evidence for the possible calibration and use of an inclination magnetic compass that can be used under all local free-flying field conditions. During …

Susceptibility, Preference, And Suitability Of Carpinus And Ostrya Taxa For Gypsy Moth Larvae (Lepidoptera: Lymantriidae), Fredric Miller, Susan Wiegrefe

The Great Lakes Entomologist

Twenty Carpinus taxa and three Ostrya taxa, growing in the tree breeding production area at The Morton Arboretum, Lisle, IL, were evaluated in laboratory bioassays for feeding susceptibility, preference, and suitability for gypsy moth (Lymantria dispar, L.) larvae. No-choice and multiple-choice laboratory feeding studies revealed that C. coreana, C. fargesii, C. laxiflora, and the hybrid C. caroliniana x C. orientalis were the least suitable for larval development and pupation, and were less preferred by gypsy moth larvae. Suitability rankings for gypsy moth larval development time were highly correlated with larval longevity, but the proportion of …

Influence Of Age On Decision Making By Ovipositing Pieris Rapae (Lepidoptera: Pieridae)., Brett Breitkreutz, Tracy Le Wagner, Rodrigo J. Mercader

The Great Lakes Entomologist

Due to its effect on the time available for host selection and learning, butterfly age is expected to alter the degree of host specificity and potentially niche breadth. Here, we use the small cabbage white, Pieris rapae L., to test the effect of age on ovipositional specificity and decision-making time. Specifically, we examined the ovipositional behavior of P. rapae 4, 8, and 12 days post-emergence. Females were recorded in thirty-minute trials using leaves of two hosts, mustard leaves, Brassica juncea, and collard greens, Brassica oleracea Acephala group, and the non-host common bean, Phaseolus vulgaris. Subsequently, we measured …

Sunsat Design Competition 2014-2015 Second Place Winner – Team Sunflower: Thermal Power Satellite, Keith Henson, Steve Nixon, Kris Holland, Anna Nesterova

Online Journal of Space Communication

Space-based Solar Power has failed to be competitive on cost in spite of decades of study. A new approach appears to resolve the cost issue, undercutting coal and opening huge markets for low cost solar power from space. There are two parts to the problem. First is the cost of lifting parts to Geosynchronous Earth Orbit (GEO; second is the mass of parts that make up a power satellite.

Our team is proposing a combination that makes use of Skylon to Low Earth Orbit (LEO), and a 15,000 ton payload ground powered electric propulsion from LEO to GEO. This strategy …

Musical Architects: Immersive Learning Through Design Thinking In A Kindergarten Music Composition Curriculum, Elissa Johnson-Green

Visions of Research in Music Education

This qualitative study focuses on building a fully immersive musical-architecture composition curriculum for three general music classes of kindergarteners (N=45). Students composed original music using a set of engineering and design precepts. As part of the compositional process, they used Lego bricks to construct three-dimensional representations of their compositions. The children also wrote musical scores using their own notation as a mnemonic device, a “blueprint,” which they read while they played their pieces. They could then choose to perform their completed pieces in class and record them as part of their creative process. Each child composed using a keyboard, which …

High Precision Tissue Sampling For Mass Spectrometry, Chao Dong

LSU Doctoral Dissertations

A high precision infrared laser ablation sampling system was developed for localized tissue proteomics. A Schwarzschild reflective objective with 10 cm working distance and 0.3 numerical aperture was used to focus a mid-IR laser at 3 µm wavelength to a beam diameter of approximately 6 µm. A laser ablation spot size of 10 µm was achieved on thin ink films and tissue sections. The sampling system was used to ablate and capture rat brain tissue sections in transmission geometry. Captured tissue protein was extracted, digested, and analyzed with offline liquid chromatography tandem mass spectrometry (LC-MS/MS) for peptide and protein identification. …
