Molecular Characterization Of Hemoglobin Protein In Larvae Of 4th Instar Chironomidae For Evaluating Environmental Quality, Jun Taek Oh
Seton Hall University Dissertations and Theses (ETDs)
Studying environmental quality is a challenging task. It is a complicated exercise since the environment is constantly influenced by numerous variables such as climate change, anthropogenic activities, and unexpected natural disasters. Traditionally, exposure to chemical pollutants depended on chemical and physical analysis of environmental media. Unfortunately, this approach has not taken into consideration bioavailability of the chemical(s) of interest to exposed organisms and/or modification of the chemical (bioactivation/detoxification) by the organism. Benthic macroinvertebrates (BMIs) have been chosen as bioindicators for numerous environmental biomonitoring programs geared towards the assessment of aquatic ecosystems. Biomonitoring requires a more subtle measure – a biomarker …
Hiv-1 Transgenic Rats Display Alterations In Immunophenotype And Cellular Responses Associated With Aging, Susan J. Abbondanzo
Hiv-1 Transgenic Rats Display Alterations In Immunophenotype And Cellular Responses Associated With Aging, Susan J. Abbondanzo
Seton Hall University Dissertations and Theses (ETDs)
Advances in anti-retroviral therapy over the last two decades have allowed life expectancy in patients infected with the human immunodeficiency virus to approach that of the general population. The process of aging in mammalian species, including rats, results in changes with immune response, immunological phenotypes, and ultimately, increased susceptibility to many infectious diseases. In order to investigate the immunological pathologies associated with chronic HIV-1 disease, particularly in aged individuals, the HIV-1 transgenic (HIV-1Tg) rat model was utilized. Age matched animals were challenged using lipopolysaccharide (LPS) to determine immunological modification of HIV-1Tg animals throughout the aging process. LPS is known to …

Branching Into Rnai: Synthesis, Characterization And Biology Of Branch And Hyperbranch Sirnas, Anthony Muriithi Maina

The cancer epidemic continues to afflict millions of humans world-wide each year and despite a renewed hope with the development of new and improved forms of therapy, a cure for cancer remains an elusive goal. This is partly related to the rise of resilient forms of tumors that have evolved with resistance towards conventional chemotherapy and radiation treatments. Moreover, these non-specific therapeutic regimens are highly toxic, leading to severe immunosuppressive effects which poisons the body and compromises the road towards remission. In an effort to mitigate these limitations, cancer-targeting approaches are currently experiencing a renaissance in the translation of new …
Use Of Cholera Toxin B As A Vaccine Adjuvant Activates Antigen Presenting Cells And Stimulates Production Of Pro-Inflammatory Cytokines, Heather C. Romlein
Use Of Cholera Toxin B As A Vaccine Adjuvant Activates Antigen Presenting Cells And Stimulates Production Of Pro-Inflammatory Cytokines, Heather C. Romlein
Seton Hall University Dissertations and Theses (ETDs)
Francisella tularensis is an intracellular pathogen that has been classified as a category “A” bioterrorism agent by the Centers For Disease Control. To date, there is no approved vaccine to provide protection against this pathogen. Previous in vivo studies with mice have shown that a mucosally targeted vaccine preparation of inactivated F. tularensis (iFt) adjuvanted with Cholera toxin “B” (CTB), successfully granted full protection against a less virulent strain (FT LVS) of the bacterium and provided partial protection against a more virulent strain (SchuS4). However, the mechanisms of this protection are not fully understood. In this …
Transcriptome Analysis Of Sea Lamprey Embryogenesis, Zakary Ilya Yermolenko
Transcriptome Analysis Of Sea Lamprey Embryogenesis, Zakary Ilya Yermolenko
Seton Hall University Dissertations and Theses (ETDs)
The sea lamprey (Petromyzon marinus) has survived throughout evolution for hundreds of millions of years. It is considered an invasive species to the Great Lakes that has caused dramatic changes in the ecosystem for fish communities resulting in the collapse of a fishing industry that was previously valued at billions of dollars. Successful management of the sea lamprey is essential to a sustainable fishing industry and biodiversity. Therefore sea lamprey embryos were studied at various stages of development by growing them in a simulated habitat. RNAs from adult female ovaries and embryos at different time points during embryogenesis …
Chemical Induced Hypoxia Differentially Affects Gene Expression In Human Neuronal Cells, Natasha V. Pavlichko
Chemical Induced Hypoxia Differentially Affects Gene Expression In Human Neuronal Cells, Natasha V. Pavlichko
Seton Hall University Dissertations and Theses (ETDs)
Previously, our laboratory used desferoxamine (DFO), to generate hypoxic conditions (a low oxygen condition) which decreased human neuronal cell viability, but some cells still survived. These surviving neurons showed no morphological changes when compared to the non-treated group. However, the alteration of several intracellular events were detected, such as an increase of hypoxia inducible factor 1 (HIF-1) mRNA levels, a decrease of human mu opioid receptor (hMOR) message, and no change of human delta opioid receptor (hDOR) receptor message. Western blot analysis showed the Janus kinase (JAK)/ Signal Transducers and Activators of Transcription (STAT) pathway was activated and an increase …
