Office of the President Publications and Research

Background: Although adverse left ventricular shape changes (remodeling) after myocardial infarction (MI) are predictive of morbidity and mortality, current clinical assessment is limited to simple mass and volume measures, or dimension ratios such as length to width ratio. We hypothesized that information maximizing component analysis (IMCA), a supervised feature extraction method, can provide more efficient and sensitive indices of overall remodeling.

Methods: IMCA was compared to linear discriminant analysis (LDA), both supervised methods, to extract the most discriminatory global shape changes associated with remodeling after MI. Finite element shape models from 300 patients with myocardial infarction from the …

Treating Acute Migraines: Triptans Vs. Antiemetics, Samuel Reisman

The Science Journal of the Lander College of Arts and Sciences

Influential American medical organizations and publications have published guidelines for the treatment of acute migraine headaches that omit antiemetics, usually suggesting triptans as the first line of treatment. A review of the few comparative studies directly contrasting clinical outcomes of triptans and antiemetics in the treatment of acute migraines suggest that both treatment options are relatively equal in efficaciousness. The added burden of triptan usage, including an added risk of adverse effects and a high cost per dose, would seem to warrant an antiemetic-first approach to migraine treatment, as recommended by several international health communities. Possible reasons for the prominent …

Transposon Based Gene Therapy As A Treatment For Cancer, Jacob Stauber

The Science Journal of the Lander College of Arts and Sciences

Gene therapy is the use of genes to treat or prevent diseases. Diseases such as cancer, which are difficult to treat using conventional methods, can be treated using gene therapy. The transport of the therapeutic transgene can be accomplished using viral or non-viral methods. However, widespread use of viral vectors is limited due to its high cost of manufacture and safety concern. Non-viral vectors are limited in their effectiveness. The use of transposons such as the Sleeping Beauty transposon system can effectively deliver the transgene with less concern than viral vectors. This review discusses the various vectors and treatment strategies …

Why Are People With Laron Syndrome Immune To Cancer?, Raquel Margolis

The Science Journal of the Lander College of Arts and Sciences

Laron syndrome is a congenital autosomal recessive disorder that is caused by a mutation in the growth hormone receptor. People with this syndrome have an insensitivity to growth hormone. Insulin-like growth factor 1 is produced by the liver in response to GH stimulus. It is responsible for systemic GH activities. If there is something wrong with the growth hormone receptor there will be decreased levels of IGF-1. Low IGF-1 levels cause physical deformities notable short stature. Additionally, people with low levels of IGF-1 have a natural resistance to cancer. This article discusses the ways that the decreased levels of IGF-1 …

Is The Neuraminidase Inhibitor Tamiflu Effective In The Treatment Of Influenza?, Eliyakim Hershkop

The Science Journal of the Lander College of Arts and Sciences

Influenza is a disease that has caused the deaths of tens of millions people in the last century alone. The influenza neuraminidase protein is essential in the mechanism infection. It enables the virus to leave the infected cell and proliferate. Antiviral neuraminidase inhibitor drugs can be used for treatment. The drug Tamiflu is the standard of care for both treatment and prophylaxis of influenza. The Cochrane reports of 2009 and 2014 conclude that evidence is lacking to support this. Numerous bodies disagree. Cochrane also question the accuracy and credibility of many studies and agencies in support of Tamiflu. This paper …

Biological Therapy In The Treatment Of Ulcerative Colitis, Tzipora Glanzman

The Science Journal of the Lander College of Arts and Sciences

Ulcerative colitis (UC), a subdivision of inflammatory bowel disease, is a chronic disease of the large intestines. Ulcerative colitis is normally a lifelong chronic illness with times of intense flairs and remission. During a flare, the lining of the colon becomes inflamed, and develops small ulcers causing patients to experience rectal bleeding, vomiting, anemia and diarrhea. The treatment options available to treat colitis are very small, causing many patients to need a total colectomy with in the first five years of their diagnosis. However, recent advancement in bio-technology has led to the development of a large array of new therapeutic …

A Coding Variant In Tmc8 (Ever2) Is Associated With High Risk Hpv Infection And Head And Neck Cancer Risk, Caihua Liang, Karl T. Kelsey, Michael D. Mcclean, Brock C. Christensen, Carmen J. Marsit

Dartmouth Scholarship

HPV infection is a causal agent in many epithelial cancers, yet our understanding of genetic susceptibility to HPV infection and resultant cancer risk is limited. Epidermodysplasia Verruciformis is a rare condition of extreme susceptibility to cutaneous HPV infection primarily attributable to mutations in TMC6 and TMC8. Genetic variation in the TMC6/TMC8 region has been linked to beta-type HPV infection and squamous cell carcinoma of the skin, cervical cancer, HPV persistence and progression to cervical cancer. Here, we have tested the hypothesis that the common TMC8 SNP rs7208422 is associated with high-risk HPV infection and risk of head and neck …

Empagliflozin In The Treatment Of Type 2 Diabetes: Evidence To Date, Jay H. Shubrook, Babak Baradar Bokaie, Sarah E. Adkins

Faculty Publications & Research of the TUC College of Osteopathic Medicine

In the last decade, researchers have gained a greater understanding of the pathophysiologic mechanisms of type 2 diabetes as a chronic and progressive disease. One of the more recent treatment targets is the kidney. The kidneys become maladaptive in diabetes by increasing the reabsorption of glucose above the normal physiologic renal threshold. This discovery has led to the development of the sodium/glucose cotransporter 2 inhibitors (SGLT2). These agents readjust the renal threshold for glucose reabsorption to a lower level and decrease glucose reabsorption, while increasing urinary glucose when the glucose is above the renal threshold and subsequently lowering plasma glucose. …
