Pediatrics Faculty Publications

Sickle cell anemia (SCA) is an inherited hemolytic anemia with compensatory reticulocytosis. Recent studies have shown that increased levels of reticulocytosis during infancy are associated with increased hospitalizations for SCA sequelae as well as cerebrovascular pathologies. In this study, absolute reticulocyte counts (ARC) measured prior to transfusion were analysed among a cohort of 29 pediatric SCA patients receiving chronic transfusion therapy (CTT) for primary and secondary stroke prevention. A cross-sectional flow cytometric analysis of the reticulocyte phenotype was also performed. Mean duration of CTT was 3.1 ± 2.6 years. Fifteen subjects with magnetic resonance angiography (MRA) -vasculopathy had significantly higher …

Pediatrics Faculty Publications

Premature children are prone to severe viral respiratory infections in early life, but the age at which susceptibility peaks and disappears for each pathogen is unclear.

Methods: A retrospective analysis was performed of the age distribution and clinical features of acute viral respiratory infections in full-term and premature children, aged zero to seven years.

Results: The study comprised of a total of 630 hospitalizations (n = 580 children). Sixty-seven percent of these hospitalizations occurred in children born full-term (>37 weeks), 12% in preterm (32–37 weeks) and 21% in severely premature children (<32 weeks). The most common viruses identified were rhinovirus (RV; 60%) and respiratory syncytial virus (RSV; 17%). Age-distribution analysis of each virus identified that severely premature children had a higher relative frequency of RV and RSV in their first three years, relative to preterm or full-term children. Additionally, the probability of RV- or RSV-induced wheezing was higher overall in severely premature children less than three years old.

Conclusions: Our results indicate that the vulnerability …

Phage Therapy As A Mrsa Treatment, Miriam Sussman

The Science Journal of the Lander College of Arts and Sciences

This paper seeks to review how previous research on bacteriophage therapy can be utilized to improve the treatment of MRSA infections. Due to the growing phenomenon of antibiotic resistance, scientists are looking to utilize the natural antibacterial qualities of bacterial viruses called phages to fight MRSA infections. In order to improve the therapeutic methods of combatting MRSA, one must first understand the mechanics of how phages infect bacterial cells and lyse them with their proteins. The narrow host range of bacteriophages causes the infection of only the pathogenic bacteria and maintains the state of the normal flora. Research suggests that …

Most Efficient Methods To Treat Breast Cancer, Esther Ehrman

The Science Journal of the Lander College of Arts and Sciences

Breast cancer is rampant in today’s world. Because there are many different cases and so many different ways to classify breast cancer, a multidisciplinary approach must be taken. Many patients undergo breast conserving surgery which creates a need for the eradication of any remaining tumor residue through radiation. Fifty Gy of radiation should be applied to the breast with an additional 16 Gy as a boost. If a mastectomy is performed to remove a large tumor and 4 or more positive lymph nodes were present, radiation should be applied as well. If the tumor expresses HER2 protein, Trastuzumab should be …

Hexokinase Ii Localization Is Independent Of Ampk Activation In Hela Cells, Alyssa Brown

Graduate School of Biomedical Sciences Theses and Dissertations

In order for a cancer cell to thrive, it must alter its metabolism to produce the energy needed for rapid growth. Cells accomplish this by the Warburg Effect, or switching metabolism to aerobic glycolysis, where a cell can rapidly break down sugar into ATP, lactic acid and additional byproducts. Hexokinase 2, the enzyme that catalyzes the first committed step of glycolysis, may also be upregulated in cancer cells to increase glucose breakdown. Similar proteins for metabolism are found in both S. cerevisiae and mammalian cells. S. cerevisiae regulates metabolism through glucose repression, by Snf1 (mammalian homolog: AMPK) activation, which aids …

Vertebral Metastasis As The Initial Manifestation Of Colon Cancer, Tushina Jain, Renee Williams, Benjamin Liechty, Lea Ann Chen

Medicine Faculty Publications

Oncology guidelines currently recommend against performing colonoscopies in the workup of adenocarcinoma of unknown primary unless colonic malignancy is otherwise suggested by clinical signs or symptoms. We present 2 cases of metastatic colonic adenocarcinoma that presented only with neurologic symptoms from vertebral metastasis. Although bony metastases are a rare presentation of colon cancer and colonoscopy is not warranted in the initial workup of adenocarcinoma of unknown primary, we describe these cases as a reminder that bony metastases do not rule out a colon cancer diagnosis.

Utility And Origin Of Blood-Based Autoantibodies For Early Detection And Diagnosis Of Neurodegenerative Diseases, Cassandra Demarshall

Graduate School of Biomedical Sciences Theses and Dissertations

Autoantibodies are self-reactive antibodies that have been widely implicated as causal agents of autoimmune diseases. They are found in the blood of all human sera, regardless of age, gender, or the presence or absence of disease. While the underlying reason for their ubiquity remains unknown, it has been hypothesized that they participate in the clearance of blood-borne cell and tissue debris generated in both healthy and diseased individuals on a daily basis. Although much evidence supports this debris clearance role, recent studies also suggest a causal role for autoantibodies in disease. My thesis work has focused on this "cause and/or …

Treatment Options For Skin And Soft Tissue Infections Caused By Methicillin-Resistant Staphylococcus Aureus, Renee Weinberg

The Science Journal of the Lander College of Arts and Sciences

Staphylococcus aureus is a pathogen responsible for common skin infections, such as impetigo, cellulitis, folliculitis, and abscess and it is the most common cause for skin and soft tissue infections (SSTI). Humans are carriers of this microorganism and are responsible for facilitating its spread around the world. Over time it has developed resistance to multiple antibiotics, such as penicillin and methicillin, which has made S. aureus a persistent problem in the healthcare world today. Its methicillin resistance has given it the more commonly known name methicillin-resistant S. aureus (MRSA). MRSA was initially discovered solely in the healthcare environment and thus …

Stem Cell Therapy And Macular Degeneration, Brenda Stern

The Science Journal of the Lander College of Arts and Sciences

Macular degeneration is the leading cause of vision loss in Americans sixty years and older. Currently, it is an incurable disease. Stem cell therapy is the idea of transplanting stem cells to replace damaged cells in the body. As the demand for transplantable organs far outweighs the supply, stem cells are an encouraging alternative to replace damaged cells. Can stem cell therapy be the first cure for macular degeneration? Many experiments have been done on transplanting stem cells into the eyes of rats with macular degeneration yielding promising results. The first transplantation of retinal pigmented epithelial stem cells into humans …

Uric Acid-Induced Adipocyte Dysfunction Is Attenuated By Ho-1 Upregulation: Potential Role Of Antioxidant Therapy To Target Obesity, Komal Sodhi, Jordan Hilgefort, George Banks, Chelsea Gilliam, Sarah Stevens, Hayden A. Ansinelli, Morghan Getty, Nader G. Abraham, Joseph I. Shapiro, Zeid J. Khitan

Internal Medicine

Increased uric acid levels have been implicated in the pathogenesis of metabolic syndrome. To examine the mechanisms by which this occurs, we hypothesized that an increase in heme oxygenase 1, a potent antioxidant gene, will decrease uric acid levels and adipocyte dysfunction via suppression of ROS and xanthine oxidase (XO) levels.We examined the effect of uric acid on adipogenesis in human mesenchymal stem cells (MSCs) in the presence and absence of cobalt protoporphyrin (CoPP), an HO-1 inducer, and tin mesoporphyrin (SnMP), an HO activity inhibitor. Uric acid increased adipogenesis by increasing NADPH oxidase expression and elevation in the adipogenesis markers …
