Hepatocyte Growth Factor And Its Receptor Are Expressed In Cardiac Myocytes During Early Cardiogenesis, Daniel A. Rappolee, Anand Iyer, Yogesh Patel

Department of Obstetrics and Gynecology Research Publications

In the mouse, the heart primordium arises when mesodermis set aside during gastrulation, is induced by pharyngeal endoderm, migrates ventrally to the midline of the embryo, forms a tube, and begins beating. Little is known of the molecular mechanisms that mediate the determination, mitosis, differentiation, and migration that lead to the beating heart. Transcripts for hepatocyte growth factor/scatter factor (HGF) and its receptor are coexpressed transiently and dynamically in the premyocardium but not in other heart progenitor cells. Transcripts for HGF ligand and receptor are first detected before cardiac function and looping and persist through the first looping stage, when …

Site-Specific (Local) Delivery Of Antibiotics From Biodegradable Gms Based Implants For The Prevention Of Post-Operative Wound Infections, Saleh Allababidi

MUSC Theses and Dissertations

Systemic administration of prophylactic antibiotics has been reported to significantly decrease, but not eliminate postoperative infections mainly due to the failure in achieving adequate levels of antibiotics at the surgical wound. The local administration guarantees the delivery of adequate levels of antibiotics and is therefore advantageous as a prophylactic measure. Hence, the overall objective of this study was to develop a glyceryl monostearate (GMS) based biocompatible, bioerodible system to provide short term (1-3 days) local delivery of antibiotics. GMS based matrices were prepared by direct compression. Erosion enhancers were incorporated into the GMS matrix to facilitate the bioerosion and bioabsorption …

Studies On Ara-C-Induced Dna Damage And Apoptosis In Acute Myeloid Leukemia Cells Which Overexpress P26bcl-2, Gloria Joan Bullock

MUSC Theses and Dissertations

High expression of p26Bcl-2 in patient-derived AML cells has been associated with poor response to chemotherapy including Ara-C. It has been well established that Bcl-2 over expression blocks apoptosis or programmed cell death induced by a wide variety of stimuli including chemotherapeutic drugs. However, the exact mechanism of action of Bcl-2 in promoting this blockade is still largely unknown. To determine the types of Ara-C-induced DNA damage with which Bcl-2 specifically interferes, HL-60/neo and HL-60/Bcl-2 cells were created via retroviral-mediated transfection of the bcl-2 gene. These transfectants served as in vitro AML cell models that expressed different levels of p26Bcl-2. …

Our Hearts Were Once Young And Gay: Health Care Rationing And The Elderly, George P. Smith Ii

Scholarly Articles

Although there exists no rigid guideline delineating society's obligation to provide health care, at a minimum Americans are entitled to an adequate level of care without excessive burdens being placed upon them. Fulfilling this ostensibly simple mandate, however, presents an enormous challenge. The need to allocate limited financial and human resources increasingly clashes with the moral desire to provide health care resources to elder Americans beyond their years of economic productivity. As a result, health care professionals face the difficult task of weighing against society's other priorities the efficiency of distributing limited health care resources to the elderly. This demand …

The Role Of Social Support Networks In The Independent Functioning Of Elderly Persons, Maree Gabbedy

Theses : Honours

There is conclusive evidence which highlights the importance of physical and mental health in the ability of elderly persons to function within society, and elderly persons who require services to maintain their independence, are assumed to have lower levels of functioning than persons who do not apply for, or require assistance. Individuals, however, are rarely totally independent, as most people are involved in social networks, where the reciprocal exchange of money, emotional support, goods and services are exchanged with friends family and neighbours. This study, examined the role of social support networks in the independent functioning of the elderly, in …

Phase Ia/Ib Trial Of Anti-Gd2 Chimeric Monoclonal Antibody 14.18 (Ch L4.18) And Recombinant Human Granulocyte-Macrophage Colony-Stimulating Factor (Rhgm-Csf) In Metastatic Melanoma, James Murray, Eugenie Kleinerman, Shu-Fang Jia, Michael Rosenblum, Omar Eton, Antonio Buzaid, Sewa Legha, Merrick Ross, Lora Thompson, Mansoor Saleh

Haematology and Oncology, East Africa

We performed a phase Ia/Ib trial of chimeric anti-GD2 monoclonal antibody 14.18 (ch14.18) in combination with recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) to determine the maximum tolerated dose as well as immunologic and biologic responses to the regimen. Sixteen patients with metastatic malignant melanoma received escalating doses of ch14.18 (15-60 mg/m2) administered intravenously for 4 h on day 1. Twenty-four hours later, subcutaneous injections of rhGM-CSF were administered daily for a total of 14 days. Significant side effects were related to ch14.18 infusion and consisted of moderate to severe abdominal and/or extremity pain, blood pressure changes, headache, nausea, diarrhea, peripheral …

Numerical Chromosome Abnormalities In Sperm From Oligoasthenoteratozoospermic Patients And Fertile Males, Myung-Geol Pang

Theses and Dissertations in Biomedical Sciences

Artificial fertilization protocols have been developed which bypass natural barriers for reproduction. One aspect of infertility which has received little attention is the potential importance of aneuploidy in sperm. To more clearly understand the cytogenetic make-up of sperm from OAT patients, multi-probe, multi-color FISH was performed to determine aneuploidy.

The introduction of intracytoplasmic sperm injection (ICSI) has revolutionized protocols used in in vitro fertilization centers. The pregnancies resulting from ICSI suggest an increased frequency of sex chromosome aneuploidy in livebirths. Preliminary data by others' suggest that sperm tail swelling patterns following hypo-osmotic swelling (HOST) can be predictive of fertilizing ability. …

Stimulation Of Alpha 1(I) Procollagen Gene Expression In Nih-3t3 Cells By The Human T Cell Leukemia Virus Type 1 (Htlv-1) Tax Gene., E. Munoz, D. Suri, S. Amini, K. Khalili, Sergio A. Jimenez

Selected Works of Sergio Jiménez, MD, MACR

The mechanisms that regulate the expression of genes encoding extracellular matrix proteins in fibroblasts and other mesenchymal cells have remained elusive. Studies from several laboratories have indicated that Tax, a trans-regulatory protein from the human T cell leukemia virus type I not only augments viral gene expression but also triggers the expression of various cellular genes. Here, we examined the hypothesis that the expression of collagen genes may also be modulated by Tax. NIH-3T3 cells were simultaneously transfected with a Tax expressor plasmid and a chimeric construct containing regulatory sequences (-804 to +42 bp) of the alpha 1(I) procollagen gene …

Selective Increases In Antibody Isotypes And Immunoglobulin G Subclass Responses To Secreted Antigens In Tuberculosis Patients And Healthy Household Contacts Of The Patients, R Hussain, G Dawood, N Abrar, Z Toossi, A Minai, M Dojki, J J. Ellner

Department of Pathology and Laboratory Medicine

Mycobacterium tuberculosis-specific antibodies (immunoglobulin M [IgM], IgE, IgG, and IgG subclasses) were determined in 164 tuberculosis patients (pulmonary involvement, n = 135; lymph node involvement, n = 29), 59 healthy household contacts (HC), and 51 healthy endemic donors (EC) by a quantitative enzyme-linked immunosorbent assay for reactivity with culture filtrate. Among the isotypes, significant differences between tuberculosis patient groups with either pulmonary or lymph node involvement and healthy control groups (HC and EC) were detected only for IgG (P < 0.001) and IgG1 (P < 0.001) antibodies. Pulmonary patients also showed a significant difference with IgM (P < 0.01) and IgE (P < 0.05) antibodies. HC showed elevation of only IgM antibodies compared with EC, indicating that IgM antibodies may be an indicator of recent infection with M. tuberculosis. These results suggest that the switching of IgM antibody response to IgG1 is a critical event in disease progression. Polyclonal IgG1, IgG3, and IgE antibodies also showed significant elevation (P < 0.05) in patients compared with EC. A strong correlation (rho = 0.254; P < 0.003) was observed between M. tuberculosis-specific IgG1 and polyclonal IgG1 in patients, suggesting that activations of antigen-specific and polyclonal antibodies are related events. No correlation was found between IgG1 antibodies and purified protein derivative skin test results. Since IgG1 antibody responses to culture filtrate are present only after disease establishment, IgG1 responses could provide a useful diagnostic marker of disease.

Biochemical And Molecular Characterization Of The Prostate-Specific Membrane Antigen (Psma), John Karl Troyer

Theses and Dissertations in Biomedical Sciences

Prostate cancer is the most common malignancy and the second leading cause of cancer death in males in the United States. Additionally, the number of deaths attributed to prostate cancer is increasing at a rate of approximately 8% a year. Development of new diagnostic and therapy strategies are needed in order to improve the life expectancy of patients with this disease. One tool which may allow for improvements in prostate cancer diagnosis and therapy is the monoclonal antibody (MAb) 7E11-C5.3 which was first described in 1987. Since then, the antigen recognized by MAb 7E11-C5.3 has been named the prostate specific …

Expression Of Genes Encoding Antioxidant Enzymes In Preimplantation Mouse And Cow Embryos And Primary Bovine Oviduct Cultures Employed For Embryo Coculture., M B Harvey, M Y Arcellana-Panlilio, X Zhang, G A Schultz, A J Watson

Obstetrics & Gynaecology Publications

Preimplantation embryos from a variety of mammalian species contrast markedly in their response to culture in vitro. Murine preimplantation embryos display a wider tolerance than other mammalian species to culture environments, and this has contributed to the development of several effective defined culture media. Embryo coculture on somatic cells remains the most effective method of supporting reasonable rates of bovine preimplantation development in vitro. The patterns of gene expression for several antioxidant enzymes during preimplantation murine and bovine development were examined by use of the reverse transcription-polymerase chain reaction technique to determine whether the differential developmental capacity of mammalian preimplantation …

Identification Of An Idiotypic Peptide Recognized By Autoantibodies In Human Immunodeficiency Virus-1-Infected Individuals, Q. L. Wang, H.-T. Wang, Edwin Blalock, Sybille Müller, Heinz Köhler

Markey Cancer Center Faculty Publications

Antibodies against HIV-1 proteins in HIV-1-infected individuals share a cross-reactive idiotype defined by the monoclonal antiidiotypic antibody 1F7 (5). Using a computer algorithm based on the molecular recognition theory, regions of inverse hydropathy between the variable sequence of 1F7 and human monoclonal anti-HIV-1 antibodies were identified, which are assumed to be involved in idiotype-antiidiotype contacts. A peptide was designed from the proposed contact in the variable heavy chain framework 3-complementarity determining region 3 (FR3-CDR3) of human antibodies and was synthesized. This peptide is recognized by the antiidiotype 1F7 and inhibits the binding of 1F7 to human anti-HIV-1 antibodies which express …

Astrocytes Derived From P53-Deficient Mice Provide A Multistep In Vitro Model For Development Of Malignant Gliomas., Alan M. Yahanda Md, Facs, J M Bruner, L A Donehower, R S Morrison

PCI Publications and Projects

Loss or mutation of p53 is thought to be an early event in the malignant transformation of many human astrocytic tumors. To better understand the role of p53 in their growth and transformation, we developed a model employing cultured neonatal astrocytes derived from mice deficient in one (p53 +/-) or both (p53 -/-) p53 alleles, comparing them with wild-type (p53 +/+) cells. Studies of in vitro and in vivo growth and transformation were performed, and flow cytometry and karyotyping were used to correlate changes in growth with genomic instability. Early-passage (EP) p53 -/- astrocytes achieved higher saturation densities and had …

Constitutive Alzheimer's-Type Tau Epitopes In A Neuritogenic Rat Cns Cell Line, Mary P. Lambert, Shasta Sabo, Chi Zhang, S. Ather Enam, William L. Klein

Section of Neurosurgery

Paired helical filaments (PHFs) of Alzheimer's disease (AD) largely comprise hyperphosphorylated forms of the cytoskeletal protein tau. AD-type tau phosphoepitopes, detected by various monoclonal antibodies, are absent from normal adult neurons, but recent studies have shown that their expression may contribute to neuritogenesis and axon differentiation in the developing nervous system. Therefore, we have examined a brain nerve cell line that is spontaneously neuritogenic for possible expression of AD-type tau epitopes. The neuritogenic rat brain cell line B103 was found to constitutively produce two AD-related epitopes of tau, detected by cellular immunofluorescence studies with the PHF-1 and Alz-50 monoclonal antibodies. …

Immune Response To The Carcinoembryonic Antigen In Patients Treated With An Anti-Idiotype Antibody Vaccine, Kenneth A. Foon, Mala Chakraborty, William J. John, Amanda Sherratt, Heinz Köhler, Malaya Bhattacharya-Chatterjee

Markey Cancer Center Faculty Publications

We have generated an IgG1 murine monoclonal anti-idiotype antibody (Ab2) designated 3H1, which mimics a specific epitope on the carcinoembryonic antigen (CEA). Patients with CEA positive tumors are immunologically "tolerant" to CEA. We used 3H1 as a surrogate for CEA for vaccine therapy of 12 patients with advanced colorectal cancer. Each of the patients received a minimum of four intracutaneous injections of aluminum hydroxide precipitated 3H1 at either 1, 2, or 4 mg dosage per injection. 9 of 12 patients demonstrated anti-anti-idiotypic (Ab3) response to 3H1. All nine patients generated specific anti-CEA antibody demonstrated by reactivity with radiolabeled purified CEA; …

Identification And Characterization Of Mitochondrial Dna Variants In Alzheimer's Disease, Natasha Singh Hamblet

Theses and Dissertations in Biomedical Sciences

Alzheimer's Disease (AD) is a complex neurodegenerative disorder that affects a significant portion of the human population regardless of ethnicity or gender. A mitochondrial hypothesis of AD has been proposed based on a number of studies which establish altered oxidative phosphorylation (OXPHOS) and ATP synthesis in AD tissue. ATP demand is most prevalent in the brain; damage to OXPHOS could severely impair brain metabolism, thereby leading to a decline in cognitive function. Four out of five complexes in the OXPHOS pathway are partly encoded by mitochondrial DNA (mtDNA); thus, this may be a crucial site of lesions that alter brain …

In Vitro Expression Of Human Zona Pellucida Protein 3, Chih-Wei Chen

Theses and Dissertations in Biomedical Sciences

Human zona pellucida protein 3 (hZP3) is the putative receptor on the zona pellucida of the mature oocyte that recognizes and binds sperm, and therefore plays a critical role in fertilization.

A full length cDNA of hZP3 (1278 bp) was amplified from the human ovary mRNA by reverse transcription-polymerase chain reaction (RT-PCR). The hZP3 cDNA was subcloned into PSK and pREP4 expression vectors. The cDNA of hZP3 was further characterized by restriction mapping, PCR, auto-sequencing and Southern blot analysis by using an internal oligonucleotide probe, and found to be identical to the one reported by J. Dean. Using autosequencing, 289 …

Posttraumatic Stress Disorder In Parents Of Traumatic Brain Injury Patients, Carol Farr

Loma Linda University Electronic Theses, Dissertations & Projects

Traumatic Brain Injury (TBI) produces cognitive, behavioral, and affective deficits with resulting problems such as improper social behavior, increased aggression, emotional, personality and characterological changes. The impact upon the survivor, the sibling, as well as the parental subsystem has been well documented in the literature. Post-Traumatic Stress Disorder (PTSD) has been diagnosed in several different types of trauma survivors, although rarely have individual psychological symptoms been studied in parents.

This research examined the possible vulnerability factors that are associated with TBI and their potential influence upon PTSD symptomology. Questionnaires were mailed to 266 parents of TBI patients with a response …

A Model Of Cytomegalovirus Association With The Development Of Heart Graft Atherosclerosis, Evan Skowronski

Loma Linda University Electronic Theses, Dissertations & Projects

The development of graft atherosclerosis in heart transplant recipients has been associated with the development of post-transplant cytomegalovirus infection. The mechanism of this involvement, however, remains unclear. I undertook a study to determine the role of cytomegalovirus in the development of graft atherosclerosis. First, a rapid method of detecting cytomegalovirus based on capillary polymerase chain reaction and gel electrophoresis was employed to determine the presence of cytomegalovirus in a wide variety of clinical samples. Detection of cytomegalovirus is a lengthy procedure under normal conditions, and timely detection of cytomegalovirus in transplant recipients may allow intervention early enough to block the …

Persistent Oral Dyskinesias Induced By Long-Term Haloperidol Treatment Is Dissociated From Changes In Neostriatal B(Max) And Mrna Content For Dopamine D(2) Receptors, Nuoyu Huang

Electronic Theses and Dissertations

Due to the presumed associations of dopamine (DA) receptor supersensitivity phenomena in both long-term neuroleptic-treated tardive dyskinetic rats and neonatal 6-hydroxydopamine (n6-OHDA)-lesioned rats, we studied the influence of haloperidol on n6-OHDA-lesioned rats. At 3 days after birth rats received 6-OHDA-HBr (200 $\mu$g, bilateral intracerebroventricularly; desipramine pretreatment, 20 mg/kg, 1h) or vehicle. Two months later haloperidol (1.5/kg/day $\times$ 2 days/week for 4 weeks, then 1.5 mg/kg/day, every day for 10 months) was added to the drinking water. Spontaneous oral activity of intact and n6-OHDA-lesioned rats receiving haloperidol was reached and maintained at significantly higher levels after 15 weeks of haloperidol treatment. …
