In Vitro/In Vivo Activation Of Angiostatin, Jason C. Anderson

Electronic Dissertations and Theses

Angiostatin is a proteolytic fragment of plasminogen that inhibits angiogenesis. It destroys newly formed capillaries and causes tumors to stop growing, shrink, or disappear altogether. We sought to determine if angiostatin could be produced from plasminogen by urokinase enzyme. We hypothesized that if angiostatin is produced, it could be an inhibitor of endothelial cell growth. To test this idea, plasminogen was purified by affinity chromatography using a sepharose-lysine column. Then, it was incubated with urokinase and 10% sodium azide. In order to produce angiostatin, samples were taken out at different time periods and analyzed on SDS-Page Gel electrophoresis gel designated …

An Investigation Into The Toxicity Of 1,3-Butadiene And Its Metabolite (Monoepoxybutadiene) On Prostate Cancer Cells, Siobhian M. Bacchus

Electronic Dissertations and Theses

1,3-Butadiene is a colorless, non-corrosive gas with a mild aromatic or gasoline like odor. Manufacturing, transporting and usage are the main sources of l,3-butadiene pollution in the environment. 1,3-butadiene is kno wn to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans and animals. The primary routes of potential human exposure to 1,3-butadiene are inhalation, ingestion, and dermal contact. 1,3-butadiene is metabolized in experimental animals and human liver microsomes to epoxide metabolites, initially 1,2-epoxy-3-butene and subsequently 1,2:3,4-di epoxybutane, by cytochrome P450 enzymes. There are significant species differences in the metabolism of 1,3-butadiene both in vivo …

Do Cellular Phones Cause Headaches?, Jasmine Gay

McCabe Thesis Collection

Many people have recently complained about experiencing headaches in association with the use of their cellular telephones. There is much controversy over this subject because it has not yet been proven that the microwaves emitted by cellular telephones cause headaches. The research questions include the following: What are the effects, if any, of the use of cellular telephones on human health? Do they cause headaches? Are they responsible for the increase in size of some brain tumors?

There have been many experiments performed by various scientists in the field of bioelectromagnetics and by the World Health Organization (WHO); however, these …

Effects Of Protein Level And Gender On Estimation Of Lean Gain Per Day Of Pigs From A Terminal Crossbreeding System, G.W. Libal, C.R. Hamilton, J.N. Tembei

South Dakota Swine Research Report, 2001

Lean growth potential is currently used to typify pigs when designing nutritional programs The most common method of estimating lean growth type is by measuring gain over the growth-finsih period and obtaining carcass information for the pigs evaluated. This information is placed in a model to calculate lean gain/day. Excess protein is fed to ensure that the genetic potential for lean gain per day is not limited by nutrition. The data reported herein are the results of determining the lean growth potential of the SDSU research herd in 1992 with pigs fed two different protein regimens.

Effect Of Diet Complexity On The Performance Of Newly Weaned Pigs Fed Pharmacological Levels Of Zinc Oxide, D.Y. Lee, G.W. Libal, C.R. Hamilton, D.N. Peters

South Dakota Swine Research Report, 2001

Zinc (Zn) is an essential trace mineral for swine. The requirement for Zn has been suggested to be in the range of 50 to 100 mg/kg for pigs at various stages of growth. The bioavilability of zinc oxide (ZnO) as a source of Zn is lower than other Zn sources such as zinc sulfate (ZnSO4), zinc carbonate (ZnCO3) and Znmethionine in weanling pigs. Recent studies have shown that adding pharmacological levels (2000-4000 mg/kg) of Zn as ZnO to corn-soybean meal based diets improved started pig performance and was effective in controlling E. coli scours for weanling pigs. Very high levels …

Effect Of Formulating Diets To Reduce Excess Amino Acids On Performance Of Growing And Finishing Pigs, G.W. Libal, D.N. Peters

South Dakota Swine Research Report, 2001

For every stage of growth, pigs have a requirement for essential amino acids provided in a specific ratio and for additional nitrogen provided as amino acids or other nitrogen sources to allow synthesis of nonessential amino acids. The typical manner of balancing swin diets has involved supplying several traditional feed ingredients in a ratio in the diet that meets the required level of the most limiting amino acid leaving excesses of most other amino acids. With this method, considerable nitrogen above that needed for nonessential amino acid synthesis is provided and excess nitrogen is excreted in the urine as urea. …

Influence Of Corn Density On Pig Growth And Nutrient Digestibility, E.L Hansen, G.W. Libal, C.R. Hamilton, D.N. Peters

South Dakota Swine Research Report, 2001

The pricing of corn is baded upon a number of factors including moisture content, test weight, level contaminants, and deterioration of quality. It is understood that high moisture content dilutes the concentration of energy and nutrients. Poor quality because of deterioration during storage and the presence of contaminants lowers the palatability of the ingredient and may have negative health ramifications With less logical reasoning it has been assumed that the feeding value of corn for pigs is related to corn’s bulk density. Low-test weight corn is sold at a discount even if moisture content and quality factors are desirable. Corn …

Evaluation Of A Macrophage Attenuated Isolate Of Prrsv As A Vaccine For Porcine Reproductive And Respiratory Syndrome Virus, C.D. Nelson, R.R. Rowland, D.H. Zeman, D.A. Benfield

South Dakota Swine Research Report, 2001

PRRS continues to be the most economically important disease of swine. While the acute reproductive disease is still prevalent, chronic, or endemic PRRS in nursery and grow/finish pigs is a major problem confronting most swine producers. Post-weaning problems in these herds include a 50-85% reduction in growth rates; a 10-30% increase in unmarketable pigs; and a 10-25% increase in psot-weaning morality. Popular protocols to manage PRRSV infections include bredding herd stabilization; elmination of seronegative sub-populations of susceptible gilts; nursery depopulation; and more recently mass vaccination/unidirectional pig flow in the grow/finsih unit. The goal of this project is to determine if …

Effects Of Dietary Energy Concentration During The Grower Period On The Accuracy Of Determining Lean Gain Potential During The Finisher Period For Pigs Selected During The Grower Period By Either A Lean Gain Formula Or By Plasma Urea Nitrogen Concentration As An Indicator Of Lean Gain, J.N. Tembei, G.W. Libal, C.R. Hamilton, D.N. Peters

South Dakota Swine Research Report, 2001

It is generally thought that pigs eat to satisfy their demand for energy and the amount of feed consumed is dependent on the energy density of the diet. Therefore, the amount of feed consumed when an energy-dense diet is fed will be lower than when a low energy diet is fed. Protein is the nutrient that is most frequently adjusted as energy density in the diet is changed. Energy intake influences the rates of deposition of lean and fat tissue. Nitrogen accretion is generally limited by voluntary intake of energy for pigs weighing less than 50 kg but not for …

Serum Concentrations Of Igf-1 And Steroids In Growing Boars, Barrows And Gilts., J.A. Clapper, L.A. Rempel

South Dakota Swine Research Report, 2001

It is known that boars, barrows, and gilts grow at different rates and with varying defficiencies. Gilts generally eat less, grow slower, but are more efficient and have leaner carcasses than. One way in which growth may be regulated in pigs is through changes in circulating IGF-I and (or) IGF binding proteins (IGFBPs) Insulin-like growth factors-I has been shown to stimulate amino acid and lgucose uptake and increase protein synthesis, while IGFBPs can function to inhibit or protentiate the actions of IGFs. Estradiol has been demonstrated to regulate expression of the IGF system. Administration of estradiol increased serum concentrations of …

Effects Of High Protein/Low Carbohydrate Swine Diets During The Final Finishing Phase On Pork Muscle Quality, J.M. Leheska, D.M. Wulf, J.A. Clapper, R.C. Thaler

South Dakota Swine Research Report, 2001

Pork color and water-holding capacity defects (pale, soft and exudative, or PSE pork) are functions of muscle pH and cost of the U.S. pork industry $60 million per year (Morgan et al., 1994). Pork with a low ultimate hP (pH<5.5) has a paler color and lower water-holding capacity. Lactic acid build-up is responsible for lowering pH from 7.0, at the time of death, to 5.2-6.0 at 24h postmortem. Postmortem glycolysis produces lactic acid and can only occur in the presence of the substrate glycogen. Therefore, more glycogen in the muscle at slaughter will result in more lactic acid build up and a lower ultimate pH, which will result in a paler color and a lower water-holding capacity (Ellis et al, 1997) Consumption of carbohydrates is the main source of glucose in the blood (Guyton and Hall, 1996). In human studies conducted by Snitker et al., (1997) eight adult males were given one of two isoenergetic diets: a high-carbohydrate diet (75% of energy as carbohydrate, 15% as protein, and 10% as fat), or a low-carbohydrate diet (10% of energy as carbohydrate, 15% as protein, and 75% as fat) for three days. After the three day dietary maniuplation, glycogen content in the vastus lateralis muscle was significatnly lower for the low-carbohydrate subjects; 296 vs 426 mmol glucose/kg dry muscle, respectively (P<0.001) (Snitker et al., 1997). Therefore, this study was conducted to determine if feeding ultra-high protein/low carbohydrate swine diets during the final finishing phase could reduce muscle glycogen and thereby imporve pork muscle quality.

The Distribution Of Prrs S:P Ratios In Prrs Negative Case Submissions, W.B. Epperson

South Dakota Swine Research Report, 2001

Porcine reproductive and respiratory syndrome (PRRS) is an important viral disease of swine. A popular way to diagnose PRRS infection is by detection of PRRS antibodies using a comercial system (HERDCHECK PRRS ELISA-IDEXX Laboratory, Westbrook, ME). For each sample tested, the system measuers PRRS antibodies and compares the concentration of antibody in the sample with the concentration of antibody in a known positive sample. The system outputs this result as an S:P ratio (sample: positive). Ratios ≥0.40 (the “cut-off” point) are interpreted to mena the sample is PRRS positive. We have observed that animals originating from PRRS negative herds have …

Effects Of Feeding Diets Formulated With Amino Acid Profiles Intended For High-, Medium-, And Low-Lean Gain Pigs On The Performance Of Medium-Lean Gain Pigs, G.W. Libal, C.R. Hamilton, D.N. Peters

South Dakota Swine Research Report, 2001

The University of Nebraka and South Dakota State University published a Swine Nutrition Guide with nutrient recommendations for pigs in a four-phase feeding system for 20 to 114 kg. The recommendations utilized the concepts of split sex feeding, ideal protein profile relative to lysine, and reduction of nitrogen excretion by lowering the total protein content of the diet with dietary supplementation with economically available amino acids The research reported in this paper was an attempt to evaluate the consequences of feeding diets formulated for three lean groth genotypes to pigs of the medium-lean growth type.

Effect Of Nursery Pen Group Zize On Performance And Weight Variation Of Pigs Weaned At 10 To 20 And 20 To 30 Days Of Age, G.W. Libal

South Dakota Swine Research Report, 2001

Current trends in the swine industry are for management of pigs in larger groups well beyond that which has been recommended. With larger groups there is the potential for higher stocking rates because of more effective pig space per pen, savings in cost of dividing fences, and, in some cases, feeding equipment. However, with larger groups, more initial weight variation within a pen would be expected due to less sorting and more social competition because of more pigs per pen. It is unclear if these potentially negative factors would result in poorer pig performance during the nursery period and/or more …

Serologic Response Of Gnotobiotic Pigs Challenged With Actinobacillus Pleuropneumoniae Serotype 5 Or Actinobacillus Suis Field Isolates, C.C.L. Chase, K. Wright, J. Torrison, L.J. Braun

South Dakota Swine Research Report, 2001

Three studies, a pilot study with conventional early-weaned pigs and two studies with gnotobiotic pigs were completed. The piolot study indicated that conventional pigs could be challeneged with at least 107 colony forming units (cfu) or Actinobacillus pleuropneumonia (APP) or Actinobacillus suis (A suis) without developing clinical signs. No serological response was detected in these pigs. In the first gnotobiotic study, nine pigs were used: 3 control, 3 APP or 3 A. suis. The two groups of challened pigs failed to respond clinically or serologically to the intial callenege of 106 cfu or either APP or A. suis but the …

The Effect Of Diet And Oral Antibiotic Therapy On Immune Function And Productivity In Young Pigs, C.C.L. Chase, D.J. Hurley, R.C. Thaler, T.E. Lucas

South Dakota Swine Research Report, 2001

Medicated early weaning programs have been shown to be an excellent method to control disease incidence in the young pig. Additional research by Dritz, et al1, showed that early weaning at 7-10 days without medication resulted in significant weight gains over conventional weaning at 14-17 days. We were interested in the effects of low levels of conventional water and feed grade antibiotic tratments on performance and immunological parameters of the young pig in a commercial operation. Previously, we had tested this treatment at a research facility and had shown increased production and a decreased polyclonal immunological response in the reated …

Thermal Environmental Effects And Group Size On Growing Swine Immune Status, S.H. Pohl, D.J. Hurley, R.C. Thaler, C.C. Chase

South Dakota Swine Research Report, 2001

The effects of environmental conditions on the immune system of growing pigs (30-50 kg) were studied using T and B cell proliferation counts. Pigs were exposed to a constant 32°C ambient temperature versus a naturally occurring diurnal temperature variation during hot weather and a constant 10°C vs 21°C ambient temperature during cold weather. In addition, T and B cell proliferation counts were compared for pigs in single, 9 and 18 pigs/pen group sizes. Concancavalin A (ConA), Phytohemagglutinin (PHA) and Staphylococcal enterotoxin B (SEB) mitogens were used to determine T cell activation over time. Pokeweed (PWM), Lipopolysaccharide (LPS) and Salmonella typhimurium …
