Treating Carcinomas Through Integrin Α6Β4 Modification And Inhibition, Pearl Singer Jan 2020

Treating Carcinomas Through Integrin Α6Β4 Modification And Inhibition, Pearl Singer

The Science Journal of the Lander College of Arts and Sciences

Integrin α6β4 is a membrane protein which is expressed in both normal and cancerous epithelia. In normal cells, it is involved in adhesion to the basal membrane. In carcinomas, however, it takes on cell signaling roles related to survival and migration. Due to its key role in cancer progression, it is now being considered as a therapeutic target. This paper examines how we can affect integrins, with a specific focus on integrin α6β4, to reinforce their ability to prevent migration of cancer cells and progress toward metastasis.


Which Hypothesis Best Explains The Development Of Cancer?, Ariel M. Mayer Jan 2020

Which Hypothesis Best Explains The Development Of Cancer?, Ariel M. Mayer

The Science Journal of the Lander College of Arts and Sciences

There are three theories of cancer development analyzed in this review. The first theory is the immunological theory, which states that cancer is a result of the immune system failing to detect a cancerous cell in which results in uncontrolled cell growth. The second theory is the somatic mutation theory, which states that genetic mutations are a direct cause cancer. The third theory is the stem cell theory which states that cancer results from an uncontrolled stem cell. The difference in each theory helps guide a clinician’s judgment in how to treat cancer. If a clinician believes in the immunological …

It is necessary to analyze the materials being used and determine whether they interact with the body in a detrimental manner. This will enable dental professionals to choose the most beneficial material to utilize for …


Uterine Transplantation: A Review Of Some Of The Factors That Account For The Success Or Failure Of This Experimental Procedure, Rachel Stern Jan 2020

Uterine Transplantation: A Review Of Some Of The Factors That Account For The Success Or Failure Of This Experimental Procedure, Rachel Stern

The Science Journal of the Lander College of Arts and Sciences

Those who suffer from infertility, either due to a congenital or acquired cause and cannot or are opposed to other means, such as surrogacy or adoption, to have a child, are potential candidates for uterine transplantation. Uterine transplantation is a form of allograft transplantation, meaning that it is a transplant of tissue from a donor who is genetically different from the recipient. Additionally, it is a vascularized transplant, including donor blood vessels that will be sutured to the vasculature of the recipient (Testa et al. 2017). This procedure has been attempted around the globe with varying levels of success ranging …


What Is The Future Of Organoids?, Michelle Freilich Jan 2020

What Is The Future Of Organoids?, Michelle Freilich

The Science Journal of the Lander College of Arts and Sciences

The term organoid refers to a miniature version of any organ of the body. An organoid is artificially produced in vitro from stem cells or tissue that possess the ability to recapitulate and form the three-dimensional structure of the organ they were once a part of. Scientists have learned to create a culture for the organoid that mimics its original micro cellular environment, allowing the 3-D structure to self-organize and develop into miniature organs. The purpose of this paper is to explore the many advancements of organoid technology, and how this progress has benefited the medical field. Organoid technology allows …

With obesity on the rise, and subsequently numerous diseases, many people are looking for newer ways to counter the effects of the influx of fatty, high sugar and unhealthy foods they are consuming. The most common and widely used method is a diet plan. The key to both a healthy and effective diet is knowing what the diet does to the body. There are short term diets which have adverse effects if kept for too long and long-term diets which are aimed for a healthy lifestyle. Every diet is based on the increased and decreased consumption of different macronutrients and …


Human Organ/Limb Regeneration: A Dream Or Reality?, Shmuel Sashitzky Jan 2020

Human Organ/Limb Regeneration: A Dream Or Reality?, Shmuel Sashitzky

The Science Journal of the Lander College of Arts and Sciences

Organ and limb regeneration might seem like something out of science fiction, but research has been ongoing since the late 1960s and has greatly increased at the turn of the century. It is an understatement to say that this has the potential to be life changing. The need for donor transplant organs and transplant waiting lists can become obsolete and the use of immunosuppressants post-transplant will become unnecessary (leading to higher survival rates). Should this happen, trauma patients will be able to achieve complete recoveries and the reign of some congenital disorders will come to an end. Nature has provided …

Human Genetics, Psychotropic Drugs, And Acts Of Violence, Selma Jolanda Eikelenboom-Schieveld Jan 2020

Human Genetics, Psychotropic Drugs, And Acts Of Violence, Selma Jolanda Eikelenboom-Schieveld

Electronic Theses and Dissertations

From the start of the use of psychoactive prescription medications in the 1950s, physicians reported paradoxical adverse reactions, ranging from newly developing depressions to an increase in existing mood disorders, and extremely violent and bizarre acts of suicide and homicide. In this research, it is hypothesized that the pharmacological properties of the prescribed drugs or the interaction between the drugs and the enzymes that are primarily responsible for their metabolism (cytochrome P450s) could cause these reactions. Given that acts of violence could be medication-induced, the role of the rate of drug metabolism is discussed. Genetic testing of certain CYP450s could …

Structural Features Of 1,3,4-Thiadiazole-Derived Ligands And Their Zn(Ii) And Cu(Ii) Complexes Which Demonstrate Synergistic Antibacterial Effects With Kanamycin, Dariusz Karcz, Arkadiusz Matwijczuk, Daniel Kaminski, Bernadette Creaven, Katarzyna Lecka-Szlachta, Karolina Starzak

Articles

Classical synthetic protocols were applied for the isolation of three novel 1,3,4-thiadiazole derivatives which were then complexed with the biologically important Cu(II) and Zn(II) ions. All free ligands and their corresponding complexes were characterized using a number of spectroscopic techniques including Ultraviolet-visible (UV–vis), Fluorescence, Infrared (FT-IR), tandem liquid chromatography-mass (LC-MS), X-ray diffraction (XRD), and Nuclear Magnetic Resonance (NMR) spectroscopy (1H, 13C, HSQC, HMBC). The results obtained are consistent with the formation of dihydrate complexes, in which the chelation of the metal ion occurs via one of the thiadiazole nitrogen atoms and the deprotonated hydroxyl group of the …

What Are The Most Appropriate Treatments, Preventions And Family Planning Options For Patients With Factor V Leiden?, Simha Wolf

The Science Journal of the Lander College of Arts and Sciences

The management of Venous Thromboembolism in terms of treatments and prevention has been well researched for patients who have been discovered as positive for Factor V Leiden genetic clotting disorder, in either the homozygous or the heterozygous genotype. In fact, the research and development of new agents called Direct oral anticoagulants aim to treat and prevent clotting events while minimizing the risks of bleeding. Although several risk factors have been identified in relation to VTE, Factor V Leiden mutation presents a seemingly higher risk due to its unpredictable incidences of clotting events, even in patients with optimal health characteristics. Yet, …

Is Hyperbaric Oxygen Therapy Effective For Treating Autism?, Malky Meyer Jan 2020

Is Hyperbaric Oxygen Therapy Effective For Treating Autism?, Malky Meyer

The Science Journal of the Lander College of Arts and Sciences

Autism spectrum disorder (ASD) is characterized as a developmental disability caused by abnormalities in brain function. Studies link ASD with various physiological abnormalities, such as cerebral hypoperfusion, oxidative stress, inflammation, and mitochondrial dysfunction. Studies show that diminished blood flow to the brain demonstrates a connection between several core autistic behaviors, and the hypoperfusion generally worsen with age, growing more prevalent in older children. Although hyperbaric oxygen therapy (“HBOT”) is not yet approved by the United States Food and Drug Administration ) (“FDA”), several studies performed internationally have proven its efficacy in treating people with autism. Even so, the FDA does …

The Feeding Pattern Of C57bl/6j Mice, Yakshkumar Dilipbhai Rathod

Browse all Theses and Dissertations

The feeding pattern and control of energy intake in social mice are poorly understood. Here, we determined and quantify the normal nocturnal feeding pattern of group-housed male and female mice of the C57BL/6J genetic background fed a chow diet. Mice at 10 and 20weeks of age showed the expected age-dependent increase in lean and fat mass being them more pronounced in males. Under ad libitum conditions, male and female mice ate comparable amounts of food per unit of body weight irrespective of gender. The analysis of the feeding microstructure revealed that energy intake in females is the result of significantly …


Adaptive Tolerance To Sodium Chloride In Daphnia Magna, Brady P. Parlato, Rick Kopp Jan 2020

Adaptive Tolerance To Sodium Chloride In Daphnia Magna, Brady P. Parlato, Rick Kopp

Kentucky Journal of Undergraduate Scholarship

Salinity levels of some freshwater systems have been altered by humans, posing a threat to aquatic life. We hypothesized that a Daphnia magna population pre-treated with a low concentration of NaCl would develop greater salinity tolerance than an untreated population. Two Daphnia magna cultures with 60 individuals each were established, one started with 1.00 ppt NaCl and increased by 0.20 ppt weekly, and the other with pure spring water. After 4 weeks, 40 neonates from each culture were individually placed in a solution of 2.30 ppt NaCl (separately determined to be the LC50) for 48 hours. Survival was …


The Formation And Manifestation Of Kidney Stones, Adina Peikes Jan 2020

The Formation And Manifestation Of Kidney Stones, Adina Peikes

The Science Journal of the Lander College of Arts and Sciences

Conclusion:

As more research is done on kidney stones it becomes abundantly clear that even more research is needed. There are an innumerable amount of factors to take into account when determining the best course of treatment for persons with renal calculi. The patient’s occupation, ethnicity, BMI, family history, and region of residence are all contributing aspects. Stone composition may be very varied from case to case. Treatment that was successful for one may be detrimental for the other. There is no one-size-fits-all solution. Each case is unique and requires its own analysis and diagnosis. One thing is universal though, …

Intra-Ocular Vascular Endothelial Growth Factor Inhibiting Agents: Indications, Efficacy, And Alternatives, Rena Shilian

The Science Journal of the Lander College of Arts and Sciences

One of the most revealing parts of the human body is the eye. In fact, systemic conditions and diseases are commonly manifested in the eye and display pathology that reflect disorders. An example of a chorioretinal vascular condition that can present itself in the eye is diabetes mellitus, which if left uncontrolled can damage the eyes and a person’s vision. Age related macular degeneration is specific to the eye, potentially leading to irreversible loss of central vision. Intravitreal injections containing vascular endothelial growth factor inhibiting agents appear to be the leading lines of defense against diabetic retinopathy and macular degeneration …

Should Advanced Maternal Age Be A Deterrent For Attempting A Pregnancy?, Sarina Spira

The Science Journal of the Lander College of Arts and Sciences

In the developed world, the trend toward women of advanced age bearing children is very prevalent and seems likely to continue. For a variety of reasons, women are delaying pregnancy until 35 years and older when they suddenly seem keenly aware that their biological clocks are ticking. A review of various studies obtained from the Proquest and EBSCO databases indicates that there are definitely certain risks associated with advanced maternal age (AMA). As females age, the reduced number and quality of their remaining eggs contribute to reduced fertility. Congenital anomalies involving the number of chromosomes in the embryo increases as …

Advancements In Vaccine Development: Measles Vs. Covid-19, Sarah Ziegler

The Science Journal of the Lander College of Arts and Sciences

As an ever-progressing field of study, vaccine development has made headway over the past decades. By doing a comparative study between development of the measles vaccine in the mid-20th century, and the ongoing development of the COVID-19 vaccine in 2020, many of the insights and advancements in the field can be easily highlighted. First, the knowledge and experience gained over those decades has helped the vaccine developing process become more efficient. With more vaccines in production, or at least under study, it is more likely to have a related precedent to build upon, as opposed to relying on a successful …


Effective Treatments For Nicotine Addiction, Chaya Shor Jan 2020

Effective Treatments For Nicotine Addiction, Chaya Shor

The Science Journal of the Lander College of Arts and Sciences

Nicotine dependence as a result of smoking is a chronically relapsing disorder with detrimental effects. However, fortunately for smokers, an armamentarium of smoking cessation aids is available in the forms of nicotine replacement therapy (NRT), non-nicotinic drugs (namely varenicline and bupropion), and the novel nicotine vaccines, each with their own mode of action to moderate nicotine addiction. This paper analyzes the mechanism of action associated with nicotine addiction and the various methods of combat, or at the very least, attenuation of the addiction.

Is Rapamycin An Effective Anti-Aging Drug?, Basya Aboud

The Science Journal of the Lander College of Arts and Sciences

Scientific and pharmaceutical advancements have revolutionized medicine. Many once- debilitating or fatal diseases can now be managed with medication. However, the search for a cure for the inevitable aging diseased state remained futile until recently. Rapamycin has been studied for its possible longevity effects, providing promising results for the development of anti-aging therapies. This paper evaluates the benefits and risks of rapamycin use. While rapamycin cannot be supported as a safe anti-aging drug, rapamycin studies have elucidated parts of the aging pathway, providing a breakthrough for anti-aging research.


What Role Does Age-Associated Neuroplasticity Play In The Efficacy Of Cochlear Implantation?, Jacob Fliegelman Jan 2020

What Role Does Age-Associated Neuroplasticity Play In The Efficacy Of Cochlear Implantation?, Jacob Fliegelman

The Science Journal of the Lander College of Arts and Sciences

Bilateral, profound-severe, congenital deafness causes widespread structural and functional changes of the auditory system. In humans, the consequences of these changes are extensive and often include detriments to language acquisition and auditory perception. Fortunately, early intervention methods, such as cochlear implantation, can significantly mitigate inevitable auditory deficiencies. This review begins by briefly addressing early stages of brain development and associated anatomical discrepancies observed in congenitally deaf subjects. Considering the deleterious effects of congenital deafness, neuroplasticity, the ability of the brain to rewire itself, is of paramount importance in reversing the auditory impairments. Hence, its incorporation into the methods required for …

Total Cellular Atp Production Changes With Primary Substrate In Mcf7 Breast Cancer Cells., Maggie Louie, Justin Ton, Maurice L. Brady, Diem T. Le, Jordon N. Mar, Chad A Lerner, Akos A Gerencser, Shona A. Mookerjee

Natural Sciences and Mathematics | Faculty Scholarship

Cancer growth is predicted to require substantial rates of substrate catabolism and ATP turnover to drive unrestricted biosynthesis and cell growth. While substrate limitation can dramatically alter cell behavior, the effects of substrate limitation on total cellular ATP production rate is poorly understood. Here, we show that MCF7 breast cancer cells, given different combinations of the common cell culture substrates glucose, glutamine, and pyruvate, display ATP production rates 1.6-fold higher than when cells are limited to each individual substrate. This increase occurred mainly through faster oxidative ATP production, with little to no increase in glycolytic ATP production. In comparison, non-transformed …


Variations On A Theme: Intricacies Of Unanchored Poly-Ubiquitin Signaling And Toxicity, Jessica Renee Blount-Pacheco Jan 2020

Variations On A Theme: Intricacies Of Unanchored Poly-Ubiquitin Signaling And Toxicity, Jessica Renee Blount-Pacheco

Wayne State University Dissertations

Ubiquitin is an 8.5 kDa post-translational modifier involved in essentially all eukaryotic cellular processes. Through a process called ubiquitination, ubiquitinating enzymes chemically attach ubiquitin to substrate proteins to control their fates, resulting in anything from their recruitment into signaling pathways to their proteasomal degradation, with a plethora of possibilities in between. Ubiquitin molecules can also be attached to one another, resulting in poly-ubiquitin chains with various effects depending on the number of ubiquitin molecules and the specific amino acid residues used to link them together. While most poly-ubiquitin in the cell exists as conjugated species, there are also untethered poly-ubiquitin …
