An estimated 14.1 million people are diagnosed with cancer worldwide every year and gastric and ovarian cancers are in the top five most diagnosed. Gastric cancer has a 5-year survival rate of 28%, while ovarian cancer has a 5-year survival rate of 40%. In several cases of gastric and ovarian cancers, the TACC (transforming acidic coiled coil) genes, particularly TACC1 and TACC3, are expressed abnormally. Studies on bladder cancer, lung cancer, and glioblastoma have shown a translocation occurring between the TACC genes and the FGFR genes (fibroblast growth factor receptor), specifically FGFR1 and FGFR3. This translocation produces a TACC-FGFR fusion gene, the resulting protein of which can be used as a target in new drug inhibiting treatments. Thus identification of TACC-FGFR rearrangements in tumors could be vital to effective cancer cell regression. However, studies to locate this rearrangement in gastric and ovarian cancers have not been carried out. For our research project, we plan to investigate whether or not the TACC-FGFR translocation is involved in the progression of gastric and ovarian cancers. To do this we will first validate a known TACC-FGFR translocation in the RT4 bladder cancer cell line using reverse-transcription (rt)-PCR analysis. Then we will use validated TACC-FGFR primers to perform an analysis on 20-30 gastric and ovarian tumor samples. Comparing the tumor results to the known RT4 line will allow us to determine if the TACC-FGFR translocation is present during gastric and ovarian tumor development. Identifying this rearrangement in gastric and ovarian cancers could lead to groundbreaking treatments that could potentially save millions of lives.
The goal of this research was to conduct small-scale induction expression studies on the sodium -channel toxin protein from the venom of the scorpion Centruroides vittatus. Several toxin genes were previously isolated by an earlier research group, and sequence analysis from the isolated genes showed variation between two genes: Na667 and Na668 toxins. This particular experiment is centered on further analysis of Na667. After the toxin genes were transferred into appropriate cells, protein expression was chemically induced via isopropyl -D-1-thiogalactopyranoside (IPTG). Different strains of plasmid vectors and expression cells were used in an effort to determine which vector and cell combinations allowed optimal growth and induction of the toxin protein. Based on SDS-PAGE analysis, Rosetta 1019/Na 667 cells showed the greatest induction. We determined that the protein of interest weighs approximately 45 kDa, as shown on SDS-PAGE results. As scorpion toxins are of great medical importance for their impacts on human cell physiology, these experiments will be continued with larger scale induction expression studies and varying induction parameters.
Based on industry standards and normal animal husbandry practices surgical castration is done when pigs average 10 days of age without any pain relieving dedication. With animal welfare becoming an ever increasing issue in animal production agriculture, suggestions have been made for the use of systemic pain relief to mitigate post-procedural pain. This research was designed to evaluate if the administration of a systemic pain relief medication given post- procedure would improve the pig's recovery process. In order to test this hypothesis intact male pigs from two farrowing groups were randomly assigned to one of two treatment groups. The treatment groups consisted of castrates receiving either 0.5mg/kg of body weight of Meloxicam post-procedure or equivalent dose of distilled water (control). At initiation of the test each pig's weight was taken and recorded and dosage calculated for each treatment. Weights were also taken and recorded on day 2, 4 and 7 post-treatment. Weight gain post-procedure is used as an indication of recovery time. Preliminary results suggest there was no significant improvement in weight gains between animals that received pain relief medication and the control group.
Laser beam profilers are an important tool for studying laser beams. A disadvantage of commercially available beam profilers is the cost which is typically around $3,500. This research was pursued to find a viable replacement using a low cost CCD from a security camera (available for ~$40). A program had to be developed and implemented. A benefit to this is that the profiler can be programed to take a variety of measurements. This low cost beam profiler is capable of measuring relative intensity, beam width, and beam quality of the laser.
Two linkage isomers composing of diironhexacarbonyl clusters coupled to and p-toluenethiolate ligands have been usefully prepared and structurally characterized. The crystal structure of [(-toluenethiolate)2Fe2(CO)6] has been determined by X-ray crystallography. The influence of the and p-toluenethiolate ligands on the electronic and electrochemical properties of the iron-carbonyl unit has been investigated using infrared spectroscopy, UV-visible spectroscopy and cyclic voltammetry and the results will be presented. These compounds are mimics of the active site of the hydrogenase enzyme. They are therefore of interest as electrocatalysts for the reduction of proton to produce molecular hydrogen, a clean alternative to fossil fuels.
The most common obstruction to Earth-space optical communication links is cloud cover. For this reason, the statistical characterization of clouds above potential optical communication ground station locations is greatly important. A weatherproof, infrared camera has been deployed to gather and process cloud coverage data. It provides accurate readings during the day and at night with constant sensitivity. It is also equipped with its own data processing software that calculates atmospheric emissions, and removes it from its images to correctly identify cloud signatures. Four years of cloud image data have been accumulated thus far and it is the duty of this project to analyze this data and build an archive of useful statistics. Monthly, weekly, and daily averages of cloud optical depth, the average length of observed clear or cloudy skies and seasonal trends in cloud coverage are just a few statistics that will be constructed. The ultimate goal is to find optical communication ground sites with statistically anti-correlated cloud cover so that optical communication from earth to space can be performed at any time.
This study examines the utility of services and supports provided to ATU students registered with the Disability Services office. This is an exploratory survey to examine the most effective supports for students with disabilities on a typical college campus. A "return on investment" model will be used to provide recommendations on how schools may prioritize supports.
While many studies have shown the negative influence of stressors upon growth in fish (see Jentoft, et al., 2005), some studies have achieved growth enhancement of body metabolism (fat production, reproduction/seasonality, and growth -- Meier et al. 1973). A short, daily disturbance (3 hours of bubbling), was applied 16 to 19 hours after light onset, in one concrete trout run, with the control run getting no bubbling disturbance. Fish growth was followed by selective sampling of trout in each run. Results and future research directions are discussed
Microsatellite DNA polymorphisms provide a wonderful opportunity for the exploitation and identification, or "fingerprinting", of many different varieties of cultivated blackberry. Reliable identification of university-bred blackberries is of great interest due to the easily-propagated nature of the valuable plants. In this study, we were able to use 20 microsatellite markers with basic PCR techniques and agarose gel electrophoresis to identify more than 30 unique cultivars of patented or pre-patented blackberry plants bred at the University of Arkansas. This project emphasizes the low-cost and efficiency of being able to use an in-house protocol to identify specific plants. We have demonstrated that a single blackberry cultivar can be positively identified for less than ten dollars within a twelve-hour period.
The use of genetically modified crops has become increasingly widespread as an ingredient in cosmetics and foodstuffs in the United States. This project is an attempt to determine the amount of genetically modified soybeans currently being grown locally as well as statewide. One of the project's objectives is to measure how knowledgeable faculty, students, and staff were concerning this widespread use. Students worked with Cooperative Extension Service Agents and personnel of the Natural Resources Conservation Service to collect soybean production data in Conway, Yell, and Pope Counties. A survey was created and delivered via e-mail to Arkansas Tech University faculty, students, and staff containing general questions designed to discover attitudes and opinions of GMO usage.
The purpose of this study is to quantify the effects of showering immediately prior to swimming on numbers of fecal contamination indicator organisms present in the swimming water. Researchers hypothesize that showering before entering swimming water will reduce the numbers of indicator organisms released by a swimmer. This study is performed by using minimal amounts of water in a controlled setting. Various treatments are applied to each water sample and subjects sit in the water wearing a typical bathing suit after either showering or not showering. Indicator organism densities were determined using the most probable number fermentation technique.
