Breast cancer is one of the most common malignancies in women. It continues to be a major burden and cause of death among women worldwide. Molecular oncology is now one of the most promising fields that may contribute considerably to diagnosis of breast cancer and its metastases addressing major problems with early detection, accurate staging, and monitoring of breast cancer patients. The overall objective of these feasibility studies was to contribute to improved diagnosis, prognosis, and prediction of breast cancer disease through the development of reagents and protocols for the use of molecular biological advances and the assessment of the …
The Effects Of Expansion On Objective And Subjective Benefit In Hearing-Impaired Listeners, Ashley B. Hill
The Effects Of Expansion On Objective And Subjective Benefit In Hearing-Impaired Listeners, Ashley B. Hill
LSU Master's Theses
The present research involves two studies. Twenty hearing-impaired participants were divided into two groups depending on their audiometric data and binaurally fit with the Starkey Endeavour 3211 hearing instruments. Experiment I was designed to determine if the use of expansion technology affected objective and subjective benefit in hearing-impaired listeners. Probe microphone measures were obtained at 40, 50, and 60 dB SPL and with the speaker deactivated to ensure that the expansion feature was functioning. Listener performance was measured in quite using the Connected Speech Test (CST) and in noise using the Hearing in Noise Test (HINT) at 40, 50, and …
Alternative Language Sample Analyses For The Assessment Of Low-Income African American Children, Christy Gayle Wynn
Alternative Language Sample Analyses For The Assessment Of Low-Income African American Children, Christy Gayle Wynn
LSU Master's Theses
The purpose of this study was to examine the clinical utility of three language sample analyses when working with low-income, African American (AA) children. Eighteen normally developing and three at-risk AA three-year-old preschoolers participated in the study. Language samples were elicited from each child during a 15-20 minute play interaction. Three language sample analyses, contrastive analysis, average sentence length, and complex syntax use, were completed on each language sample. Also coded was each child’s use of nonmainstream African American English (AAE) patterns. Only the contrastive analysis generated reliable differences between the at-risk children and the normally developing children. Other group …
The Effects Of Intra-Articular Silicone Polymer On Synovial Fluid, Synovial Tissue, And Articular Cartilage In The Equine Middle Carpal Joint, Marilyn Rumbaugh
The Effects Of Intra-Articular Silicone Polymer On Synovial Fluid, Synovial Tissue, And Articular Cartilage In The Equine Middle Carpal Joint, Marilyn Rumbaugh
LSU Master's Theses
There is anecdotal documentation that intra-articular administration of liquid silicone is used as a lubricant for equine joints. Effects of silicone polymer on equine articular cartilage and synovial fluid have not been evaluated. The objectives were to characterize the effects of intra-articular administration of liquid silicone polymer on clinical, synovial fluid, and microscopic features in normal middle carpal joints of horses, and to determine if silicone migrates to the axillary lymph nodes. Eight adult horses were used in this study. Two mLs of 1,000 centistoke, medical-grade silicone was injected into one randomly selected middle carpal joint. The opposite middle carpal …
The Effect Of High Frequency Amplification On Subjective And Objective Benefit With Digital Hearing Instruments, Erica Lynn Fleck
The Effect Of High Frequency Amplification On Subjective And Objective Benefit With Digital Hearing Instruments, Erica Lynn Fleck
LSU Master's Theses
The purpose of the present study was to determine whether amplifying beyond 3 kHz was beneficial to the user, whether the benefit was dependent on degree of loss, and whether subjective data reflected the benefit. Seventeen hearing impaired subjects were binaurally fitted with digital hearing instruments. Qualified subjects were divided into two groups, A and B. Group A had a pure tone average (3,4, and 6 kHz), of 55 dBHL or better. Group B had a pure tone average (3,4, and 6 kHz) greater than 55 dBHL but not exceeding 75 dBHL. Each subject was fit with two conditions (upward …
Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins
Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins
LSU Master's Theses
Among the gastrointestinal nematode parasites that cause the most problems to small ruminants, Haemonchus contortus is one of major concern. Currently, the control of H. contortus and others is almost entirely based on the use of anthelmintics. Consequently, anthelmintic resistance has developed worldwide and this has become a serious problem in small ruminant nematode parasite control programs. In view of this, there is a need for alternative control methods. The use of Copper-Oxide Wire Particles (COWP) to help reduce parasite burden is one such alternative. Three trials were conducted to determine the effect of COWP on the reduction of H. …
Developing Risk Assessment Maps For Schistosoma Haematobium In Kenya Based On Climate Grids And Remotely Sensed Data, Kelsey Lee Mcnally
Developing Risk Assessment Maps For Schistosoma Haematobium In Kenya Based On Climate Grids And Remotely Sensed Data, Kelsey Lee Mcnally
LSU Master's Theses
It is important to be able to predict the potential spread of water borne diseases when building dams or redirecting rivers. This study was designed to test whether the use of a growing degree day (GDD) climate model and remotely sensed data (RS) within a geographic information system (GIS), could be used to predict both the distribution and severity of Schistosoma haematobium. Growing degree days are defined as the number of degrees centigrade over the minimum temperature required for development. The base temperature and the number of GDD required to complete one generation varies for each species. A monthly climate …

A Comparative Study Of Two Treatment Approaches For Improving Middle School Students' Reading Comprehension, Vessa Annette Cartmill
LSU Master's Theses
The purpose of this study was to examine the efficacy of having material read to and discussed with learning disabled students (i.e., a compensatory approach termed Accommodated Reading in this study) compared to teaching the literate language of text structures to students (i.e., a language intervention approach termed Communicative Reading Strategies). Participants were two 5th grade students and three 6th grade students, classified as learning disabled according to criteria of the State of Louisiana. Students took part in the study 3 times per week, 40 minutes per day for 5 ½ weeks during their regular speech-language therapy time. After each …
Susceptibility Of Bacillus Anthracis To Gamma And Cherry Bacteriophage, Preston A. Fulmer
Susceptibility Of Bacillus Anthracis To Gamma And Cherry Bacteriophage, Preston A. Fulmer
LSU Master's Theses
Bacillus anthracis is a bacterium that causes severe disease mainly in ruminants, but can affect any mammal, including humans. A popular method for the detection of this organism is susceptibility of the bacterial isolate to g bacteriophage. However, to date no study on the resistance of a wide variety of B. anthracis isolates has been conducted. The following study examines the rate of resistance of a wide range of B. anthracis isolates to g phage as well as another phage specific for B. anthracis known as Cherry phage. We also compared susceptibility to phage with another detection method, susceptibility to …
The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich
The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich
LSU Master's Theses
Vaccination programs are designed to protect an animal from infection, however, depending upon the age and health of the animal vaccination may not stimulate a protective humoral response. It is possible that, as in the human and mouse models, geriatric equines may be less responsive than their younger counterparts to current vaccination protocols. The purpose of this study was to identify an age related diminution in the primary and secondary immune responses of geriatric horses in response to vaccination. Two groups of horses were sampled. The first group consisted of an open herd of 39 privately owned horses, varying in …
Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary
Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary
LSU Master's Theses
Helicobacter hepaticus is well established as an unwanted variable in laboratory rodent colonies. Historically, caesarean section and embryo transfer have been used to derive Helicobacter-free mouse colonies. Neonatal transfer of newborn mice onto Helicobacter-free foster dams was recently reported as an alternative method of deriving Helicobacter-free mice, but until now, the age by which pups must be fostered to remain Helicobacter-free was unknown. The purpose of this study was to determine the age by which mouse pups must be fostered to remain H. hepaticus-free. Beginning on the day of birth, 20 C57BL/6 mice were fostered from H. hepaticus-positive parents onto …
