Secreted Factors From Human Umbilical Cord Blood Cells Protect Oligodendrocytes From Ischemic Insult, Derrick Rowe

USF Tampa Graduate Theses and Dissertations

Oligodendrocytes (OL)s are the dominant cell type in the white matter and are integral for synaptic transmission essential for proper neuronal communication between brain areas. Previous studies have shown that intravenous administration of the mononuclear fraction of human umbilical cord blood (HUCB) cells in rat models of stroke reduced white matter injury, gray matter injury and behavioral deficits. Yet the mechanisms used by HUCB cells remain unknown in ischemic injury. These studies will investigate both in vitro and in vivo approaches to elucidate this mechanism in OLs. When mature primary OLs were coincubated with HUCB cells, HUCB cells secreted soluble …

Exhausted Or Unlicensed: Can Field-Of-Use Restrictions In Biotech License Agreements Still Prevent Off-Label Use Promotion After Quanta Computer?, Kristal M. Wicks

The University of New Hampshire Law Review

[Excerpt] “In the biotechnology (biotech) industry, companies must be increasingly aware of their intellectual property and how their licensing strategies can impact their rights. When licensing patented technology, it is common practice for biotech companies to include restricted field-of-use provisions in their license agreements. Such provisions permit a licensee to only use licensed technology in a defined field and restrict use or development in another field. This licensing strategy plays an important role within the biotech industry because it allows companies to more effectively control their intellectual property and to more efficiently research and develop pharmaceutical products.

Anticancer And Antifungal Activity Of Copper(Ii) Complexes Of Quinolin-2(1h)-One-Derived Schiff Bases, Bernadette S. Creaven, Brian Duff, Denise A. Egan, Kevin Kavanagh, Georgina Rosair, Venkat Reddy Thangella, Maureen Walsh

Articles

The condensation of substituted aromatic aldehydes with 7-amino-4-methyl-quinolin-2(1H)-one (1) has lead to the isolation of quinolin-2(1H)-one derived Schiff bases (2–14). The copper(II) complexes (2a–14a) of the ligands were also prepared, and together with their corresponding free ligands were fully characterised by elemental analyses, spectral methods (IR, ¹H and ¹³C NMR, AAS, UV–Vis), magnetic and conductance measurements. The bidentate ligands coordinated to the copper(II) ion through the deprotonated phenolic oxygen and the azomethine nitrogen of the ligands in almost all cases. X-ray crystal structures of two of the complexes, 5a and 8a, confirmed the bidentate …

Using Photoactive Vitamin Nanoparticles As Photodynamic Antimicrobial Chemotherapeutic (Pact) Agents To Treat Chronic Wounds, Rahul A. Khanke

All Capstone Projects

The objective of the proposed study is to develop new materials and methods to manage microbial growth in chronic wounds using phototherapy. Chronic wounds are considered as a worldwide health problem. The most common chronic wounds can be classified into three categories: venous ulcers, diabetic ulcers, and pressure ulcers. Venous ulcers, which usually occur in the legs, account for about 70% to 90% of chronic wounds and can become infected easily. Venous ulcers are sores that develop after veins in the legs have been damaged. These ulcers can penetrate deeply into the skin. Occasionally, if a venous ulcer persists for …

Morphological Analysis Based On A Fractional Dynamic Model For Hyphal Growth, Jonathan Blackledge, Dan Barry

Conference papers

The development of methods capable of accurately characterising the morphology of filamentous microbes represents a significant challenge to biotechnologists. This is because the productivity of many industrial fermentation processes is heavily dependent on the morphological form adopted by an organism. It is therefore of significant value if a quantitative model and associated metric(s) for morphological forms determined by complex phenotypes can be determined non-invasively, e.g. through image analysis. Specific interest is in the quantification of the branching behaviour of an organism. This is due to the link between branching frequency, biomass and metabolite production. In this paper we present a …

Specific, Reversible Cytostatic Protection Of Normal Cells Against Negative Effects Of Chemotherapy, Benjamin B. Mull

Dissertations and Theses (Open Access)

Chemotherapy is a common and effective method to treat many forms of cancer. However, treatment of cancer with chemotherapy has severe side effects which often limit the doses of therapy administered. Because some cancer chemotherapeutics target proliferating cells and tissues, all dividing cells, whether normal or tumor, are affected. Cell culture studies have demonstrated that UCN-01 is able to reversibly and selectively arrest normal dividing cells; tumor cells lines do not undergo this temporary arrest. Following UCN-01 treatment, normal cells displayed a 50-fold increase in IC50 for camptothecin; tumor cells showed no such increased tolerance.

We have examined the response …

Hypoxia And Fetal Programming Of Cardiovascular Dysfunction, Qin Xue

Loma Linda University Electronic Theses, Dissertations & Projects

Human epidemiological studies have shown a clear association of adverse intrauterine environment and an increased risk of ischemic heart disease in later adult life. Of all the stresses to which the fetus is subjected, perhaps the most important and clinically relevant is that of hypoxia. The goal of this project is to test the hypothesis that chronic hypoxia during gestation adversely affects fetal cardiovascular development and impairs cardiac function in offspring. In the first part of project, we tested the hypothesis that chronic hypoxia adversely regulates contractility of fetal pulmonary arteries and veins in sheep residing at high altitude (3,801 …

Weight Gain Among Adults With Intellectual Disabilities Receiving Atypical Antipsychotics, Sherri Lyn Transier

Doctoral Dissertations

The present study assessed whether the atypical antipsychotic agents olanzapine, risperidone, and quetiapine are associated with significant weight gain among adults with intellectual disabilities after 6 months of drug treatment. The body weights of 79 participants were retrieved 6 months prior to the initiation of drug treatment, at the start of the atypical antipsychotic agent, and after 6 months of drug therapy. Each individual served as his or her own control by utilizing pretreatment baseline trends in weight change to calculate a dependent measure of adjusted posttreatment weight gain. Doing so allowed for a stringent determination of the liability for …

A Role For Lipid Rafts In Egfr Tki Resistance In Breast Cancer, Mary Elizabeth Irwin

Wayne State University Dissertations

Breast cancer can be divided into genetic sub-types including luminal, HER2+, and basal-type. With the introduction of targeted therapies against estrogen receptor and HER2 receptor mortality rates of American women with breast cancer have declined. Unfortunately, basal-type breast cancers, which have the worst clinical outcome, do not express estrogen receptor or HER2, and as such, have no targeted therapeutic option. The epidermal growth factor receptor is an attractive target for therapeutics in basal-type breast cancer, as it is over-expressed in 60% of these cases. Also, over-expression of EGFR correlates with poor patient prognosis. Unfortunately, inhibitors of EGFR have shown little …

Gabab Regulation Of Methamphetamine-Induced Associative Learning, Robin Michelle Voigt

Dissertations

Addiction is a chronic, relapsing disorder for which strikingly few effective therapies exist, and there are no FDA-approved pharmacotherapies for methamphetamine (Meth) addition. There is an immense need to identify the neurobiological underpinnings of psychostimulant addiction and develop efficacious drug therapies to compliment the current mainstay treatment of behavioral/cognitive therapy.

Re-exposure to cues associated with psychostimulants (e.g., drug paraphernalia) increase neuronal activity and can elicit drug-craving and -seeking; an effect which is profound and long-lasting. A mechanism to disrupt those brain processes which are necessary to maintain the association may reduce the incidence of cue-elicited relapse.
