Modulation Of Lps-Induced Activation Of Hepatic Map Kinases, Oliver Surriga
Modulation Of Lps-Induced Activation Of Hepatic Map Kinases, Oliver Surriga
Seton Hall University Dissertations and Theses (ETDs)
Lipopolysaccharide (LPS) is a potent inflammagen that has been found to be primarily responsible for many symptoms caused by gram-negative bacterial infections. The LPS-initiated signal transduction pathways involve several terminal kinases, mainly p42/44 mitogen-activated protein kinase (MAPK), p38 MAPK and c-Jun N-terminal kinase (JNK), ultimately leading to increased expression of genes encoding such inflammatory cytokines as interleukin (IL )-1 �. IL-6 and tumor necrosis factors (TNF)-u. In this study, the effects of age on LPS-induced activation of MAPKs in the liver of rats were examined. Results show that the basal level of phosphorylated p42/44 MAPK was increased in postnatal day …

Preliminary Characterization Of Mitochondrial Atp-Sensitive Potassium Channel (Mitokatp) Activity In Mouse Heart Mitochondria, Venkat Raghav Aachi
Dissertations and Theses
Myocardial ischemia, infarction, heart failure and arrhythmias are the manifestations of coronary artery disease. Reduction of ischemic damage is a major concern of cardiovascular biology research. As per recent studies, the mitochondrial ATP-sensitive potassium channel (mitoKATP) opening is believed to play key role in the physiology of cardioprotection, protection against ischemia-reperfusion injury or apoptosis. However, the structural information of mitoKATP is not precisely known. Elucidating the structural integrity and functioning of the mitoKATP is therefore a major goal of cardiovascular biology research. The known structure and function of the cell ATP-sensitive potassium channel (cellKATP) …
The Role Of Msa In The Global Regulation Of Virulence In Staphylococcus Aureus, Vijayaraj Nagarajan
The Role Of Msa In The Global Regulation Of Virulence In Staphylococcus Aureus, Vijayaraj Nagarajan
Dissertations
Staphylococcus aureus is an important pathogen causing life threatening diseases in humans. Previously we showed that msa modulates the activity of sarA (Staphylococcal accessory regulator), which is one of a major global regulator of virulence in S. aureus. The objective of this study is to characterize the role of msa (Modulator of SarA) in the global regulation of virulence in S. aureus. Structure and function predictions were done using several computational tools and approaches to understand the nature of msa. A novel S. aureus microarray meta-database (SAMMD) was designed and developed to compare and contrast other transcriptomes with msa transcriptome. …

Characterization Of Kaposi's Sarcoma-Associated Herpesvirus Orf11 As A Possible Dutpase, Christina N. Ramirez
Seton Hall University Dissertations and Theses (ETDs)
A dUTPase is a crucial enzyme that hydrolyzes dUTP to dUMP. This reaction prevents the mutagenic or lethal misincorporation of uracil into DNA. For that reason, the enzyme is required for efficient DNA replication. Previous studies have shown that has ORFl l dUTPase-like motifs and thus may be a dUTPase. Generally, gammaherpesviruses contain six characteristic dUTPase motifs. In particular ORFl 1 and contains motifs 1, 2, 4, 6. While the characteristic motifs of gamroaberpesviruses include motifs 1, 2, 3, 4, 5, and 6, the number of dUTPase-like motifs in ORFl 1 's protein sequence is substantial. Thus, ORFl 1 may …
Analysis Of The Cyc1 Promoter In Candida Albicans, Tomica Blocker
Analysis Of The Cyc1 Promoter In Candida Albicans, Tomica Blocker
McCabe Thesis Collection
Scientists are considering two factors that may be important in the pathogenesis of C. albicans', it's capability to morph from yeast to hyphal phase, and its differences in colony morphology, cell shape, cell surface and cell permeability. (5) Unfortunately, unlike the bacteria, yeasts do not yet have proven virulence factors. However, science is suggesting that some of the major factors which contribute to the virulence of Candida are its ability to form hyphae, its ability to resist phagocytosis, its ability to adhere to epithelial cell surfaces, its ability to grow well at 37 degrees Celsius, and its ability to secrete …

Group A streptococci (Streptococcus pyogenes) is one of the most frequent pathogens of humans. It is estimated that between 5-15% of normal individuals harbor the bacterium, usually in the upper respiratory tract, without signs of disease. S. pyogenes can initiate an active infection when defenses are compromised or when the organism is able to penetrate the host's defenses. When the bacteria invade vulnerable tissues, a variety of suppurative infections can occur. Acute S. pyogenes infection may be present as pharyngitis ("strep throat"), scarlet fever (rash), impetigo (infection of the superficial layers of the skin) or cellulitis (infection of the deep …
Photodynamic Therapy, Ashley Thomas
Photodynamic Therapy, Ashley Thomas
McCabe Thesis Collection
Photodynamic therapy is a new treatment that is being introduced into the veterinary community. Photodynamic therapy is the use of light activated chemotherapy to kill cancer cells (Dougherty, 1998). It has already been approved by the US Food and Drug Administration to be used as a form of cancer treatment in humans, but has not been carried over to the veterinary community. That is until now. Photodynamic therapy is now being tested in the veterinary community in hopes to find the same results that the human medical community has when dealing with certain types of cancer. They also hope to …
Regulation Of Proto-Oncogenes Expression In Developmental Epilepsy, Mahnoush Shafiei
Regulation Of Proto-Oncogenes Expression In Developmental Epilepsy, Mahnoush Shafiei
Seton Hall University Dissertations and Theses (ETDs)
Seizures cause selective neuronal cell loss in vulnerable regions such as the hippocampus, cortex, thalamus or substantia nigra (SN) in human or experimental animals. While the HF can propagate seizures, the SN pars reticulata (SNR) regulates the spread ol seizures in an age-dependent fashion, and the pars compacta (SNC) affects extrapyramidal motor control. In mature animals, both structures are wlnerable to seizure-induced damage. In prepubescent rats, seizure susceptibility is reduced and CA 1 region rs primarily affected. The proto-oncogenes, Bcl-2 and Bax, encode specific proteins that inhibit and promote programmed cell death, respectively. In order to determine whether proto-oncogenes are …

Standardization Of An Immunoassay For The Detection Of Antibodies To B2 Glycoprotein-I, Eric N. Erickson Jr.
Seton Hall University Dissertations and Theses (ETDs)
Antiphospholipid Syndrome (APS) is an evolving autoimmune disease with numerous clinical manifestations. APS occurs in two forms: Primary Antiphospholipid Syndrome (PAPS) and secondarily in association with other autoimmune disorders such as Systemic Lupus Erythematosis (SLE). In the brief period since its discovery as a cofactor for anticardiolipin antibodies, p1-glycoprotein I (�GPI; apolipoprotein H) has been recognized as the autoantigen in the absence of anionic phospholipid when appropriately presented to human autoantibodies. Recent studies suggest that this presentation requires the surface-dependent unmasking of a cryptic epitope. Immunoassays of autoantibodies directed against p1GPI, developed through the application of suitable polymeric matrices, may …

Dissertations
Schistosomiasis is a serious disease in humans. Two species of schistosome, Schistosoma mansoni and Schistosoma haematobium, organisms that cause the disease, parasitize humans in Libya. Schistosomes require aquatic snails in their life cycle. The purpose of this study was to investigate the environmental and the host relationships of the disease in the three regions of Libya where the disease is found. These relationships include:
1) Analyses of the physical-chemical characteristics of the aquatic habitat.
2) Collection of snails to determine: a) the kind of snail species and th e ir abundance; and b) the cercarial infestation rates.
3) Infection rates …

Carbon Dioxide Fixation In Schistosoma Mansoni, Clint Earl Carter
Loma Linda University Electronic Theses, Dissertations & Projects
Adults of the blood fluke Schistosoma mansoni were perfused from the hepatic portal system of CF1 female mice sixty to seventy days post infection. The worms were then incubated in Eagle’s minimal essential medium with glutamate and 0.03 mg/100 ml of nonlabelled aspartic acid. To this medium was added 10 μc of either NaH1403, glucose-UC14 or aspartate-4-C14. The worms were found to fix carbon from the NaH1403 and to incorporate the glucose and aspartate. The amount of activity recovered in five different chemical fractions after two hours incubation was determined …

University of the Pacific Theses and Dissertations
The literature dealing with the larva of Pacific Coast brachyuran crabs is slight. The prominent papers, those of Aikawa (1927, 1928, 1929, 1933, 1937), deal with a variety of genera and offer information useful in determin- ing family relationships. A single paper by Hart (1935) also deal with a number of brachyuran larvae found in the Pacific Ocean. None of these papers, however, identifies to species any member of the genus Cancer, although one member, C. magister (Dana) is of considerable economic importance on the pacific coast of North America. In the fall of 1958 an investigation was under taken …
