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. …

Genome-Wide Analysis Of Peg3 Downstream Genes, Subash Ghimire

LSU Doctoral Dissertations

Paternally expressed gene 3 (Peg3) is an imprinted gene encoding a DNA-binding protein that is a predicted transcriptional repressor. The two studies presented here demonstrate the repressive functions of PEG3 in regulating different cellular processes and pathways, which were observed by analyzing the ChIP-seq results systematically using both bioinformatics tools and manual inspection of significant peaks. In the first part of the work, genome-wide features of ChIP-seq peaks were characterized and the potential de novo binding motif was reevaluated. Results suggested the transcriptional repressor role of PEG3 by binding to the conserved sequence motif of the target genes. …

Ontogeny And Resource Use Of Invasive Lionfish, Pterois Volitans, In Shallow Water Habitats Surrounding Summerland Key, Emily Shallow

LSU Master's Theses

The invasive red lionfish, Pterois volitans, has been shown to considerably reduce reef biomass via predation and competition in non-native ranges. Primary maintenance of lionfish is through human removal (e.g., culling), which does not sufficiently control the population due to deep-water spawning, recolonization of recently culled reefs, and ontogenetic migrations to mesophotic waters. Here, I investigated the diets and primary energy pathways during ontogeny in lionfish from the Florida Keys using stomach contents and stable isotope (δ¹³C and δ¹⁵N) analysis to better understand their role in the trophic food web. Additionally, isotopic overlap between lionfish …

An Erp Study Of The Effects Of Iconic And Nonsense Gestures On Memory Formation, Brianna E. Cairney

LSU Master's Theses

Co-speech gesture is an important part of human communication and aids in comprehension, learning, and memory. The addition of iconic gestures to speech has been shown in prior work to enhance memory for the speech. However, it remains unclear as to whether this benefit requires gestures to be meaningful, or, conversely, if any attentionally-engaging gesture will enhance memory. In the current study, we tested two theories to explain the mnemonic benefits of co-speech gesture: Dual Coding Theory, which attributes these benefits to multimodal encoding and enhanced imageability, and Attentional Highlighting Theory, which posits that gestures draw more attention to concurrent …

Evaluation Of Leucaena Genotypes, F. B. Sousa, M. R. A. Araujo, J. A. Araujo Filho, J. Sousa Neto

IGC Proceedings (1977-2023)

The objectives of this study were to evaluate the leucaena (Leucaena leucocephala) performance and to select the best genotypes, based on yield,.stability parameters, and quality parameters. Annual leucaena yields were obtained by cuts over the rainy and dry seasons. A combined analysis of variance for yield, and quality parameters was performed. Also stability parameters and coeficients of determination were estimated. The combined ANOVA for edible dry matter yield and for acid detergent fiber, and digestibility revealed a significant difference for genotypes, environments, genotypes x environments, row spacings, cutting frequencies, and cutting heights, Six genotypes of leucaena were selected …

Genotype-Environment Interaction For Forage Yield Of Vetch (Vicia Sativa L.) In Mediterranean Environments, G. Pacucci, C. Troccoli

IGC Proceedings (1977-2023)

Genotype x environment (GE) interactions limit the effectiveness of selection when selection is based only on mean yields. The objective of this study was to evaluate the amount of GE interaction for vetch forage yield in some environments of Southern Italy, and to analyze some stability parameters that can be useful in the selection of genotypes adapted to Mediterranean environmental conditions. Eleven vetch genotypes were grown in a total of 16 environments in Southern Italy. The combined analysis of variance for forage yield showed that the environment, genotype and GE interaction terms were significant at 0.01 level, suggesting a broad …

Evaluation Of Guineagrass (Panicum Maximum Jacq) Hybrids In Brazil, Liana Jank, Cacilda B. Do Valle, J. De Carvalho, S. Calixto

IGC Proceedings (1977-2023)

Guineagrass (Panicum maximum Jacq.) is responsible for a high percentage of cattle finishing and milk production in Brazil, but presents problems of pasture degradability due to high soil fertility requirements and uneven production distribution. In order to search for new varieties to reduce these problems, over four hundred apomictic accessions of guineagrass and several sexual plants were introduced to Brazil in 1982. Agronomic evaluation took place at the National Beef Cattle Research Center of the Brazilian Agricultural Research Corporation (Embrapa Beef Cattle), in Campo Grande, MS, Brazil. Breeding of the apomictic species began in 1990 using sexual x apomictic …

Pain Characteristics Among Patients With Knee Osteoarthritis In Aden, Yemen, Abdulsalam Abdullah Hadi Mohsen

Hadhramout University Journal of Natural & Applied Sciences

Knee osteoarthritis in adults is very common and is one of the most common causes of joint pain. The aim of the study was to describe the demographic characteristics and to analyze the clinical finding. It was a retrospective study conducted in Aden during the years 2015 to 2017. Data was obtained from patients’ charts and presented as frequencies, percentages, means and standard deviation. Significance was considered at P value < 0.05. The patients were 367, (males 44.4% and females 55.6%). The older patients (≥ 55 years) were (77.1%). About (39.5%) patients were mostly suffered from right knee osteoarthritis, (25.1%) suffered from left knee and (35.4%) patients have both knee osteoarthritis. Knee pain was mild in (61%) patients and in (30%) patients was moderate. The female to male ratio was 1.3:1 and their mean age was 61.0 ± 9.5 years (age ranged between 35 and 83 years). There was a significant correlation between mean ages of both genders (p = 0.001). The mean uric acid was 6.9 ± 1.6 mg/dL and the relationship between means in both genders was significant (p = 0.000). Patients were higher in the age group ≥ 55 years. Most of the right knee osteoarthritis were in females (28.6%), while bilateral osteoarthritis were predominant in males (22.1%) (P = 0.000). The relationship between the severity of knee pain and side involvement of the knee joint was highly statically significant (P = 0.000). Further prospective studies are needed.

Adaptive Selection Signatures In River Buffalo With Emphasis On Immune And Major Histocompatibility Complex Genes, Yan Ren, Callum Macphillamy, Thu Hien To, Timothy P. L. Smith, John L. Williams, Wai Yee Low

Roman L. Hruska U.S. Meat Animal Research Center: Reports

River buffalo is an agriculturally important species with many traits, such as disease tolerance, which promote its use worldwide. Highly contiguous genome assemblies of the river buffalo, goat, pig, human and two cattle subspecies were aligned to study gene gains and losses and signs of positive selection. The gene families that have changed significantly in river buffalo since divergence from cattle play important roles in protein degradation, the olfactory receptor system, detoxification and the immune system. We used the branch site model in PAML to analyse single-copy orthologs to identify positively selected genes that may be involved in skin differentiation, …
