Title: The effect of pulsing the oxidant flow on PEM fuel cell performance.
Creator: Fuchs, Michel., Florida Atlantic University, Abtahi, Homayoon
Abstract/Description: Verification of a numerical model, used to describe the processes within a PEM Fuel Cell, revealed interesting results in the fuel cell's performance. To verify the transient response of the model, the oxidant supplied to the fuel cell was pulsed at various frequencies, which led to improvements in performance. In addition two novel methods to help determine the operating conditions within a PEM Fuel Cell were developed. The first method utilized several thermocouples, evenly spaced over the...
Show moreVerification of a numerical model, used to describe the processes within a PEM Fuel Cell, revealed interesting results in the fuel cell's performance. To verify the transient response of the model, the oxidant supplied to the fuel cell was pulsed at various frequencies, which led to improvements in performance. In addition two novel methods to help determine the operating conditions within a PEM Fuel Cell were developed. The first method utilized several thermocouples, evenly spaced over the site of reaction to monitor regional temperatures, while the second method utilized a special sensor to detect regional moisture conditions. All aspects of the verification process met with limited success, since the proper level of humidification to the fuel cell was not achieved.

Title: THE FUSION OF PLANT PROTOPLASTS WITH ANIMAL CELLS.
Creator: WILLIS, GEORGE EDWARD, III, Florida Atlantic University
Abstract/Description: Parameters affecting the fusion of plant protoplasts with avian erythrocytes were studied. Protoplasts were produced from Nicotiana tobaccum L. var. H-38 by pectinolytic and cellulolytic digestion of the cell wall. Avian erythrocytes were treated with pronase in order to remove part of the glycocalyx. Polyethylene glycol was utilized to agglutinate and subsequently induce fusion between the two cell types. The effects of washing solutions and the molecular weight of the polyethylene glycol on...
Show moreParameters affecting the fusion of plant protoplasts with avian erythrocytes were studied. Protoplasts were produced from Nicotiana tobaccum L. var. H-38 by pectinolytic and cellulolytic digestion of the cell wall. Avian erythrocytes were treated with pronase in order to remove part of the glycocalyx. Polyethylene glycol was utilized to agglutinate and subsequently induce fusion between the two cell types. The effects of washing solutions and the molecular weight of the polyethylene glycol on the fusion of both cell types were delineated. The fusion reaction was monitored by white light, scanning and transmission electron microscopy. Topographical and ultrastructural studies have shown that during agglutination, localized areas of close adhesion occurred between contiguous plasmalemmae. Fusion was observed at the margins of the adhering surfaces. Avian erythrocytes containing chloroplasts or starch grains, as well as plant protoplasts containing avian erythrocyte cytoplasm were evident. Cytoplasmic mixing between the two cell types occurred within 3 hours.

Show moreThe purpose of this research is to explore and investigate the biophysical properties of living cells using microfluidics based electrical impedance sensing (EIS) technique. It provides a non-invasive approach to detect label-free biological markers in the regulation of cellular activities even at a molecular level. We specifically focus on the development, testing, and theoretical modeling of electrical impedance spectroscopy for neuroblastoma cells and endothelial cells. First, we demonstrate that the EIS technique can be used to monitor the progressive mitochondrial fission/fusion modification in genetically modified human neuroblastoma cell lines. Our results characterize quantitatively the abnormal mitochondrial dynamics through the variations in cytoplasm conductivity. Secondly, we employ a real time EIS method to determine the biophysical properties of the junctions which join one endothelial cell with one another in a monolayer of endothelial cells. In particular, we examine the role of the protein, c-MYC oncogene, in the barrier function. Our results show that the downregulation of c-MYC oncogene enhances the endothelial barrier dysfunction associated with inflammation. Finally, we measure and find that the electrical admittance (the reciprocal of the impedance) of the monolayer of endothelial cellular networks exhibits an anomalous power law of the form, Y ∝ ωα, over a wide range of frequency, with the value of the exponent, α, depending on the severity of the inflammation. We attribute the power law to the changes of the intercellular electric permeability between neighboring endothelial cells. Thus, the inflammation gives rise to relatively smaller values of α compared to that of the no-inflammation group. Furthermore, we propose a simple percolation model of a large R-C network to confirm the emergent of power law scaling behavior of the complex admittance, suggesting that the endothelial network behaves as a complex microstructural network and its electrical properties may be simulated by a large R-C network.

Title: The novel function of sJAM-C in promoting cytoskeleton rearrangement and migration in mammary epithelial cells.
Creator: Qureshi, Anila, Charles E. Schmidt College of Medicine, Department of Biomedical Science
Abstract/Description: Soluble form of Junctional adhesion molecule C (sJAM-C) has been identified to cause angiogenesis as well as chemotaxis in endothelial cells. However, the role of sJAM-C in the context of cancer has not been elucidated. Our atomic force microscopy (AFM) stiffness measurements of normal mammary epithelial cells (MCF 10A) have shown a two-fold decrease in cell's stiffness in response to sJAM-C.

However, the role of sJAM-C in the context of cancer has not been elucidated. Our atomic force microscopy (AFM) stiffness measurements of normal mammary epithelial cells (MCF 10A) have shown a two-fold decrease in cell's stiffness in response to sJAM-C. Changes in cell stiffness are indicative of modulations in a cell's mechanical properties. Our results indicated that sJAM-C increased the MCF 10A cell migration about two-fold and also promoted a three-fold increase in chemotaxis. Additionally, sJAM-C treatment resulted in considerable filamentous-actin loss and peripheral actin ring breakage. We also found activation of Rho signaling pathway to be the main mechanism behind sJAM-C mediated alterations in MCF 10A cell cytoskeleton and motility. Our data present for the first time that sJAM-C is a pro metastatic mediator for normal mammary epithelial cells.

Title: Differential cell killing of normal and transformed human lung fibroblasts by reovirus.
Creator: Loeffler, Jennifer L., Florida Atlantic University, Roner, Michael R.
Abstract/Description: When infected with reovirus ST3, strain Dearing, normal and transformed human lung fibroblasts exhibit differential sensitivities. Transformed cells (WI38 VA13 2RA) are destroyed within four days. In contrast, normal cells (WI38) maintain a productive infection for as long as two months.

Show moreWhen infected with reovirus ST3, strain Dearing, normal and transformed human lung fibroblasts exhibit differential sensitivities. Transformed cells (WI38 VA13 2RA) are destroyed within four days. In contrast, normal cells (WI38) maintain a productive infection for as long as two months. Attempts to examine the differences between these cells included the use of cDNA subtraction and a reovirus sigma 1 protein affinity chromatography column, both of which were hampered by technical difficulties. Two-dimensional gel electrophoresis revealed patterns of differential protein expression between infected and mock-infected normal and transformed cells. Visual comparison of Coomassie blue-stained gels revealed one protein which was present in uninfected normal cells but was missing in all other samples, as well as five proteins that were present in infected and mock-infected normal cells but were missing in both transformed cell samples. Autoradiography of 35S-labeled cell samples revealed an additional eleven proteins not seen with Coomassie staining. Further characterization of these proteins should uncover the mechanism of differential cell killing by reovirus.

Title: Molecular and cellular events associated with damage to rat retinal ganglion cells: Effects of brain-derived neurotrophic factor on fast axonal transport and neuronal apoptosis.
Creator: Wodarczyk, Linda, Florida Atlantic University, Charles E. Schmidt College of Science, Center for Complex Systems and Brain Sciences
Abstract/Description: The survival of rat retinal ganglion cells (RGCs) after axotomy has been shown to be enhanced by Brain Derived Neurotrophic Factor (BDNF). It was, therefore, of interest to determine whether previously observed changes in the differential regulation of fast axonally transported proteins (FTPs) occur in rat RGCs during the early response to axotomy or whether such changes are obviated by the action of BDNF at the cell body level. It was of further interest to determine whether these...
Show moreThe survival of rat retinal ganglion cells (RGCs) after axotomy has been shown to be enhanced by Brain Derived Neurotrophic Factor (BDNF). It was, therefore, of interest to determine whether previously observed changes in the differential regulation of fast axonally transported proteins (FTPs) occur in rat RGCs during the early response to axotomy or whether such changes are obviated by the action of BDNF at the cell body level. It was of further interest to determine whether these regeneration-associated changes are sustained during the period of BDNF-enhanced cell survival. It was found that, within 2 days of injury and BDNF injection, rat RGCs initiate a growth-like cellular response that includes the differential synthesis and transport of the same profile of FTPs found to be induced in axotomized animals following injection of a saline control solution. Thus, supplementation of rat RGCs with BDNF does not obviate the changes required to reinstate active cellular regrowth. It is, therefore, unlikely that the loss of a trophic factor, such as BDNF, is the signal for axotomy-induced changes. Although a single injection of BDNF at the time of injury prolongs cell survival to at least 5 days, it is not sufficient to sustain the elevation in FTPs. This result indicates that the regulatory mechanisms that promote cell growth are distinct and separate from those that promote cell survival. This study extended beyond the above findings to affirm that apoptosis of axotomized rat RGCs is mediated by the activation of the cysteine protease, caspase-3. Such activation was demonstrated within 12 hours of axotomy and appeared to become increasingly prevalent in a central to peripheral gradient, as might be anticipated by the loss of glial derived neurotrophic support. Such activation was completely prevented by intraocular injection of BDNF, indicating that BDNF acts upstream of caspase-3 to prevent the proteolytic cascade that leads to apoptosis.

Primary monolayers were passaged with 0.025% trypsin in a modified saline solution. Silky shark cells grew optimally at 29C. The population doubling time for C. falciformis cells at passage 29 was 67 hours. For G. cirratum cells at passage 6 the population doubling was 84 hours. Silky shark cells grew over a broad range of osmolalities from 315 mOsm to a 1664 mOsm with optimal growth at 650 mOsm. A medium containing 10% dimethylsulfoxide allowed for cryopreservation with greater than 65% viability upon recovery. Current theories of elasmobranch osmoregulation are discussed in light of experimental data collected from studies conducted on the silky shark cell line.

However, studies by Santos et al. have demonstrated that human telomerase has a mitochondrial entry sequence and in the presence of hydrogen peroxide it has been found inside the mitochondrion and may cause mitochondrial DNA mutations. Saccharomyces cerevisiae contains telomerase, but it does not have the mitochondrial entry sequence. To determine if the presence of telomerase in the mitochondria can induce mutations an experiment was developed in which a mitochondrion entry sequence would be fused to the S. cerevisiae telomerase enzyme. This fusion could then be screened in S. cerevisiae with an ade2 mutation for a simple color assay of mitochondrial activity. To date, no successful transformant has been identified. The frequency of incorrect ligations has been recognized and may indicate that the desired fusion is lethal to E. coli cells.

Title: Knockdown of KIF9 leads to defects in mitotic entry and progression in mammalian cells.
Creator: Alsina, Laura., Harriet L. Wilkes Honors College
Abstract/Description: Kinesin motors bind to microtubules and function in mitosis and intracellular transport depending on the position of the motor domain within the primary sequence (Hirokawa and Noda 2008). KIF9 has recently been shown to be involved in MTOC positioning and mitotic entry in Dictyostelium (Tikhonenko et al. 2009). To determine if a similar role for KIF9 exists in mammalian cells, we are using siRNA-mediated knockdown of KIF9 in COS-7 cells. Analysis of unsynchronized and cell-cycle synchronized...

To determine if a similar role for KIF9 exists in mammalian cells, we are using siRNA-mediated knockdown of KIF9 in COS-7 cells. Analysis of unsynchronized and cell-cycle synchronized cells treated with siRNA to KIF9 reveal that the transition from G2 to M phase is delayed and that mitotic progression is also affected. Additionally, our data indicates that spindle pole function during anaphase may be abnormal in cells treated with siRNA, suggesting a role for KIF9 during that stage.

Creator: Raborn, Erik., Harriet L. Wilkes Honors College
Abstract/Description: The centrosome is a dynamic and highly active organelle within the cell. It plays a pivotal role in mitosis driving several of the physical changes that are taking place. The centrosome self-replicates before mitosis in order to set up two spindle poles on opposite sides of the cell. This leads to the creation of a mother and daughter centrosomes within a cell that have distinct components. This project will examine the recruitment of proteins to the centrosome as a cell progresses through...

Show moreElectrical impedance of cells is a sensitive indicator of changes in cellular structure and biophysical characteristics. Integration of electrical impedance sensing in microfluidics can be a useful tool for characterization of blood cells for their disease state, such as sickle cell disease and malaria. The first part of this dissertation presents application of a microfluidics-based electrical impedance sensor for the study of sickle cell disease. Dynamic cell sickling-unsickling process of blood cells in response to cyclic hypoxia was measured. Strong correlation was found between the electrical impedance data and patients’ hematological parameters such as levels of sickle hemoglobin and fetal hemoglobin. In addition, application of electrical impedance spectroscopy in narrow microfluidic channel was used for label-free flow cytometry and non-invasive assay of single sickle cells under controlled oxygen level. We demonstrate the capability of this new technique in differentiating normal red blood cells from sickle cells, as well as sickled cells from unsickled cells, using normoxic and hypoxic conditions. The second part of this dissertation reports an application of electrical impedance sensing for the study of placental malaria. Testing conditions were optimized so that electrical impedance can be used for real time monitoring of different cellular and molecular level variations in this in vitro model of placental malaria. Impedance characteristics of cell proliferation, syncytial fusion and long-term response of BeWo cells to adhesion of infected erythrocytes were obtained and related to the immunostaining results and inflammatory cytokines measurements. Comparing to the conventional optical microscope-based methods, electrical impedance sensing technique can provide a label-free, real-time monitoring tool to study erythrocytes and cytoadhesion, and can further be extended to other disease models and cell types.
