Investigation Of Bovine Herpesvirus-1 Determinants Of Neuronal Infectivity In Novel Bovine Neuronal Cell Systems For Development Of A Safer Viral Vaccine Vector, Jared Rudd

LSU Doctoral Dissertations

Bovine herpesvirus-1 (BoHV-1) is the causative agent of infectious bovine rhinotracheitis and a component of the bovine respiratory disease complex. BoHV-1 is a significant burden on the cattle industry in the United States causing severe respiratory disease, abortions, loss of calves (“shipping fever”). BoHV-1 belongs to the alphaherpesvirus subfamily of Herpesviridae. Alphaherpesviruses enter axons of sensory nerves and establish life-long latency in trigeminal and dorsal root ganglionic neurons after primary infection of the oronasal or genital epithelium respectively. Modified live attenuated vaccines for BoHV-1 are commercially available but are limited in their protection while retaining the ability to establish latency …

IGC Proceedings (1977-2023)

An intense search for new cultivars amongst recently collected and introduced ecotypes from Africa is in effect since 1988, at the National Beef Cattle Research Center, of the Brazilian Agricultural Research Corporation (Embrapa Beef Cattle). After agronomic evaluations of a large collection, 21 ecotypes were pre-selected for multilocational trials and from these, eight were elected for evaluation under grazing. The objective of this trial was thus to evaluate the persistence and carrying capacity of these eight new Brachiaria brizantha ecotypes after two years of grazing. The experimental design was a randomized complete block with nine treatments and two replicates. The …

A protocol is described for rapid multiplication of elephantgrass (Pennisetum purpureum Schum.) through shoot tip culture. The plant growth medium consisted of basal medium of Murashige and Skoog (MS) and vitamins Wood Plant Medium (WPM). The medium was supplemented with 0.00; 4.44; 8.88; 13.32 and 17.76 μM of benzylaminopurine (BAP). The elephantgrass was micropropagated by axillary shoot proliferations. Maximum propagule proliferation occurred on Murashige and Skoog (MS) medium enriched with 4.4 μM benzylaminopurine (BAP), resulting an average of 4.0 shoots per explant from cultivar Mineiro and 2.19 from cultivar Pioneiro. The best height and root plantlets were obtained with …

'Stay-Green' And Non-'Stay-Green' Perennial Ryegrass In Field Swards With Different Intervals Between Cuts, D. Wilman, K. R. Kennedy, M. O. Humphreys

IGC Proceedings (1977-2023)

The purpose of this study was to investigate the effect of the 'stay-green' character, originally introduced into perennial ryegrass (Lolium perenne L.) for amenity purposes, on herbage yield, N concentration and colour in field swards of 'stay-green' forage ryegrass managed in different ways for agricultural use. The conclusions were that the introduction of the 'stay-green' character (1) confers greater greenness only at some times of year and only when there has been a sufficiently long period of regrowth, (2) is expressed only in older, as distinct from young, tillers, (3) reduces herbage yield, particularly when a long interval is …

Agronomic Evaluation Of Alfalfa Cultivars In Rio Grande Do Sul, Brasil, J. C. De Saibro, R. Battisti, T. M. S. Freitas

IGC Proceedings (1977-2023)

From April 1995 to June 1998, thirty five alfalfa (Medicago sativa L.) cultivars (cvs.) were evaluated in a field trial at the “Depressão Central” ecoclimatic region, in southern Brazil. Two years after sowing, 30 cultivars were excluded from the test due to their poor overall agronomic performance, mainly low forage DM yields. The remaining cultivars: Crioula (local genotype used as a check), Victoria, Rio and P 30 are hay-type cultivars while Alfagraze is a grazing-tolerant type. Twenty-two harvests were made and no significant differences were found for total DM yields among cvs. Crioula, Victoria, Rio and P 30; however, …

Switchgrass For Biomass Production, Monroe Rasnake, D. Parrish, Garry D. Lacefield, D. Wolf

IGC Proceedings (1977-2023)

Six cultivars of switchgrass (Panicum virgatum) were established in 1993 at Princeton, Kentucky, USA. Two harvest systems were used: two cuttings per year in mid-June and November and one cutting per year in November. Biomass yield and stand survival were evaluated. Lowland cultivars produced more biomass than upland cultivars in both cutting managements. Upland cultivars did better in a two cut system while the other cultivars showed little difference. Excellent stands of all cultivars were maintained under both cutting managements.

The Correct Identity Of Centruroides Hoffmanni Armas, 1996 (Scorpiones: Buthidae), With The Description Of A New Species From Chiapas, Mexico, Luis De Armas, Rolando Teruel

Euscorpius

The Mexican scorpion Centruroides hoffmanni Armas, 1996 was described on the basis of a supposed adult female (actually a juvenile) from La Gloria, Arriaga Municipality, southwest of the Chiapas State. In its redescription, this species was also recorded from the southeastern of Oaxaca State. Nevertheless, in the recent revision of the “thorellii” species-group of the genus Centruroides Marx, 1890, a new species from Chiapas was misidentified as C. hoffmanni and, also, an erroneous new diagnosis was given for C. hoffmanni. In the present contribution, this new species is named Centruroides concordia sp. n., and the correct identity of C. …

Lyme Arthritis: A Primer For Primary Care, Ganesh Arun, Farhan Ali, Sowmya Srinivas, Justin Nistico, Pranav Nair

Advances in Clinical Medical Research and Healthcare Delivery

Lyme disease is caused by a bacteria belonging to the Borreliaceae family. Wooded forests and terrains are affected, including those in the Northeastern United States. Teenage ticks are most commonly discovered on humans as those ticks need to satisfy their nutritional requirements for growth. They bite warm, moist areas of the body and take 24 to 48 hours to transmit the Borrelia Burgdorferi infection. Lyme disease manifests as a multisystem disorder in humans, and is known for its dermatological, neurological and rheumatological findings. For the primary care provider, Lyme disease should be on the differential in multisystem diseases. Our case …

24andmore: Using Genomics To Improve Walleye (Sander Vitreus) Stocking In Iowa, Rachel Mcdonnell

Three Minute Thesis (3MT®) at UNI

Walleye, Sander vitreus, is one of the top gamefish in Iowa. Due to poor natural reproduction in many Iowa waterbodies, populations are managed with stocking. There are two strains of walleye used to stock Iowa’s inland waters: a river strain derived from the Mississippi River near Genoa, WI and a lake strain derived from Spirit Lake, IA. Each strain may have unique characteristics relative to their environment that could affect the fitness and success of fish stocked. The goal of this study is to understand the genetic diversity within and between each strain to offer stocking guidance to the Iowa …

Genetic Effect Of Long-Term Angling Pressure On Bluegill Populations In Small Impoundments In Kansas, Morganne Borsh

Three Minute Thesis (3MT®) at UNI

Bluegill (Lepomis macrochirus) is a versatile sport fish popularly fished across Kansas. Over the last decade, Bluegill catch rates have decreased, likely from high angler harvest rates of larger individuals. Large males that exhibit parental care have high growth rates and aggressively defend nests, making them vulnerable to angling. Males that display cuckoldry behavior reach maturity sooner, exhibit slower growth rates, and are generally smaller. The goal of this study is to determine if fisheries-induced evolution resulting from long-term harvest has led to a decline in the growth rate of Bluegill. A total of 100 individuals were sampled from ten …

Temporal Baseline Of Essential And Non-Essential Elements Recorded In Baleen Of Western Arctic Bowhead Whale (Balaena Mysticetus), Samantha Shore, Dimitri Giarikos, Lawrence K. Duffy, Mickie Rae Edwards, Amy Hirons

Marine & Environmental Sciences Faculty Articles

This study established the first baseline of changing elemental concentrations in bowhead whale baleen over time (1958–1999). From previously published stable isotope data, year, season (summer or winter), and location (Beaufort or Bering/Chukchi seas) were attributed to each sample. Thirteen elements (Al, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, V, Zn) in baleen from nine subsistence-harvested bowhead whales (n = 138) were detected. Al, Cu, and Fe were the highest concentrations while Cd and V were among the lowest. Our data supports absorption as the main route of exposure to environmental elements rather than biomagnification due to …

Department of Biological & Biomedical Sciences

The rotenone-induced animal model of Parkinson's disease (PD) has been used to investigate the pathogenesis of PD. Oxidative stress is one of the main contributors of neurodegeneration in PD. Flavonoids have the potential to modulate neuronal function and combat various neurodegenerative diseases. The pre- and post-supplementation of quercetin (50 mg/kg, p.o) was done in rats injected with rotenone (1.5 mg/kg, s.c). After the treatment, behavioral activities were monitored for motor activity, depression-like behavior, and cognitive changes. Rats were decapitated after behavioral analysis and the brain samples were dissected out for neurochemical and biochemical estimation. Results showed that supplementation of quercetin …

Metabolic Engineering Of Peanut Hairy Roots Via Rna Interference To Study The Role Of Prenylated Stilbenoids Against Water Stress, Gaurav Gajurel

Student Theses and Dissertations

Abiotic stress, such as drought, causes over five-hundred million dollars in losses in peanut production per year in the world. Peanuts are known to produce antioxidant prenylated stilbenoids, however, their role in abiotic stress tolerance have not been elucidated. The overall goal of this project was to determine if selected prenylated stilbenoids play a role against water stress in peanut. To address this issue, transgenic hairy roots with the capacity to produce diverse prenylated stilbenoids using an RNA-interference (RNAi) approach were established. RNAi molecular constructs targeting a stilbenoid-specific prenyltransferase were designed, synthesized, and expressed via Agrobacterium rhizogenes-mediated transformation in peanut …
