Test Of Bpa's Estrogenic Effects On Brain Aromatase Expression, Neural Activity, And Locomotive Behavior In Zebrafish Larvae, Ryan J. Mcauley

Cal Poly Humboldt theses and projects

Bisphenol A (BPA) is a well-known endocrine disrupting chemical that mimics the effects of estrogens. Aromatase B (Cyp19a1b) is a brain-specific enzyme that converts testosterone to estrogen and is highly upregulated in response to estrogen receptor activation localized to radial glial cells. During embryonic zebrafish development, there is a small window of time denoted by an increase in neurogenesis and estrogen receptor activity. Previous studies have demonstrated that a low dose BPA exposure (0.1µM) during this window causes hyperlocomotion in larval zebrafish, yet no further explanation for this behavior change has been described. The purpose of this study was to …

Possible Causes Of Preeclampsia And Potential Treatments, Helene Weinreb

The Science Journal of the Lander College of Arts and Sciences

Preeclampsia is a common complication of pregnancy characterized by hypertension and proteinuria. Its symptoms are well-defined, but the pathophysiology is not fully understood. This paper analyzes several of the most credible causes of this syndrome and attempts to relate these to the known risk factors. Current preeclampsia treatments are examined, and special focus is given to novel experimental treatments which offer hope of ending preeclampsia and eclampsia.

By What Mechanism Does Stress Affect Ovulation?, Chana Minkowicz

The Science Journal of the Lander College of Arts and Sciences

This paper explores the many mechanisms of how stress influences ovulation. For ovulation to occur, there needs to be a series of hormones released in a specific order, and in a specific amount. This paper will discuss the various type of stress a person can experience, and which specific reproductive hormone each different type of stress disrupts. This paper will also bring proof as to how each hormone is disturbed, and by which mechanism it is disrupted. There has not been one main mechanism that has been found thus far, therefore, it is important to take into consideration the various …

What Are The Mechanisms And Effects Of Age-Related Shortening Of The Spine?, Joseph Weingarten

The Science Journal of the Lander College of Arts and Sciences

Osteoporosis and Degenerative Disc Disease can cause a loss of height in the spine. This paper focuses on the mechanisms that cause age-related loss of height and its effects. Possible relationships between receptor activator nuclear factor kappa-B ligand (RANKL) and estrogen with osteoporosis are discussed, as well as possible genetic causes. Exercise may prevent osteoporosis. Osteoporosis may cause a loss of height, vertebral fracture, a decrease in maximum lung capacity, and hip fracture. Degenerative disc disease may cause shortening of the spine. Disc height loss can result in a reduction in the range of motion and stiffness at the affected …

Can Somatic Cell Nuclear Transfer Produce Human Pluripotent Stem Cells For Regenerative Medicine?, Alexandra Iskhakov

The Science Journal of the Lander College of Arts and Sciences

In the last half a century, researchers and scientists discovered the application of somatic cell nuclear transfer (SCNT) to clone mammalian embryos to produce a line of pluripotent stem cells for medical and laboratory use. This is a breakthrough technology that is applied to stem cell research, regenerative medicine, and cloning. Somatic cells are non-germ cells that are differentiated but provide the nuclei that are transferred to enucleated oocytes. The replacement of the nuclei results in a developing embryo that contains the genetic information of the donated nucleus, which can either be transplanted into a surrogate mother to produce a …

Relaxin As A Cure For Fibrosis, Sarah Akilov

The Science Journal of the Lander College of Arts and Sciences

Until recently, relaxin has been known as a hormone that pertained to the female reproductive system. Its ability to remodel the extracellular matrix is responsible for its known reproductive effects. Current research has indicated that it may be useful as a drug to combat fibrosis. Relaxin has been proposed as an antifibrotic drug to target a variety of organs, including the skin, lung, kidney, liver, and heart. Studies done using the relaxin null knockout mouse have given scientists insight into the workings of this hormone. Human studies have also been done to test the efficacy of relaxin in its reversal …

Xenotransplantation:The Science, The Advantages, The Ethics, Chana Erlbaum

The Science Journal of the Lander College of Arts and Sciences

Xenotransplantation is a breakthrough medicinal technology that is an attempt to change the lives of millions of people. The problems in the current organ transplant system risk the lives of patients each and every day. Intense waiting periods and extremely costly procedures exemplify the stress and pressure that these patients face as an attempt to save their own lives. Xenotransplantation is the idea of growing human organs in a different species, using incredible stem-cell and CRISPR technology. This can introduce an answer to some of the issues in the current transplant system. Many technical and ethical issues are becoming relevant …

Carbazole Based Multifunctional Dopamine Agonists And Related Molecules As Potential Symptomatic And Disease Modifying Therapeutic Agents For Parkinson’S Disease, Asma S.Mohamed Elmabruk

Wayne State University Dissertations

Parkinson’s disease (PD) is a progressive neurodegenerative disease that develops from gradual depletion of dopamine (DA) and dopaminergic neurons in the substantia nigra pars compacta (SNc) with the accumulation of intraneuronal proteinaceous matter named as Lewy bodies. The four cardinal symptoms associated with PD are tremor, rigidity, bradykinesia, and postural instability. Although the exact mechanism and etiology of PD are not fully understood, several factors have been implicated in the pathogenesis and progression of PD including protein aggregation, oxidative stress, mitochondrial dysfunction, environmental, and genetic factors.

The current therapy of Parkinson’s disease is categorized into four classes: levodopa, DA agonists, …

Discovery Of Piperlongumine Derivatives As Anti-Leukemic And Anti-Prostate Cancer Agents, Yi Liao

Wayne State University Dissertations

Piperlongumine (PL) is an electrophilic anti-cancer natural product. Through non-covalent or covalent interactions with cellular targets, PL inactivates multiple oncogenic pathways and suppresses key components of cellular anti-oxidant/anti-electrophile defense systems. These actions result in pleiotropic anticancer effects and are expected to be effective to heterogeneous acute myeloid leukemia (AML) and prostate cancer (PCa). We applied two approaches to enhance the anticancer potency of PL: 1) To design PL-histone deacetylase inhibitor hybrid drugs (PL-HDACis; e.g., 1-58), and 2) To dimerize PL pharmacophore to generate a dimeric PL (DiPL) warhead that is suitable for further conjugation (e.g., 5-17). Both 1-58 and 5-17 …

Sensitivity Of Quagga Mussels (Dreissena Rostriformis Bugensis) To Cyanobacteria At Multiple Life History Stages, Anna Boegehold

Wayne State University Dissertations

Quagga mussels (Dreissena rostriformis bugensis) originate from brackish waters of the Ponto-Caspian area and are nuisance invasive species in North American and European freshwaters. Their invasion has caused major economic and ecological damages in the Laurentian Great Lakes. Through selective filter feeding, quagga mussels have promoted the growth of cyanobacteria. Harmful cyanobacteria blooms have the potential to produce toxins, which can be toxic to humans and wildlife. Although quagga mussels can increase the prevalence of cyanobacteria blooms, it is unknown how they are physiologically affected by cyanobacteria and understanding these dynamics can be useful in the management of this invasive …

Raman Spectroscopy Detects Biochemical Changes Due To Different Cell Culture Environments In Live Cells In Vitro, Mahmoud Gargotti, Esen Efeoglu, Hugh Byrne, Alan Casey

Articles

The in vitro cell culture environment can impact on cell biochemistry and cell cycle. The manifestation of such substrate-induced changes in cell cycle in the Raman microspectroscopic profiles of cell cultures is investigated at the level of nucleolus, nucleus and cytoplasm. HeLa immortalised human cervical cells and HaCaT dermal cells were cultured on three different substrates, conventional polystyrene cell culture dishes, CaF2 slides as a commonly used Raman substrate, and glass slides coated with collagen rat tail, as a mimic of the extra-cellular matrix (ECM) environment. A cell cycle study, based on percentage DNA content, as determined using propidium iodide …
