A Puzzling Case Of Glutamic Acid Decarboxylase 65 (Gad65) Neurologic Syndrome, Areeb Masood, Nina Appareddy, Raul Tovar Castro, Zan Shareef, Laura Garcia

Research Colloquium

Autoimmune encephalitis (AE) is a rare group of neurological disorders in which antibodies are directed against intracellular or surface antigens. The incidence of AE ranged from between 0.4-1.2 per 100,000 person-years between 1995 and 2015. A subset of these autoimmune encephalitides that target glutamic acid decarboxylase (GAD) are termed anti-GAD related neurological disorders. GAD is the rate-limiting enzyme involved in the synthesis of GABA from glutamate, and is expressed in neurons of the cerebral cortex, cerebellum, and hippocampus. In addition, it is found in the B-islets of the pancreas, epithelial cells of the fallopian tube, and spermatocytes of the testes. …

Beauty And The (Chemical) Beast, Abigail Novak

BUHealth

Cosmetics and personal care products (PCPs) are prominent in the daily lives of consumers. Unfortunately, there is a long history of toxic chemicals in these products that have caused serious adverse effects. As a result, the Food, Drug and Cosmetic Act (FD&C) was created to help identify ingredients with safety concerns; this remains the primary source of regulation for cosmetics and PCPs today. No additional requirement exists for federal review of ingredients or adverse event reporting. As a result, questionable ingredients with potential safety issues can still be found in products. With these regulatory deficits, some companies have taken steps …

The Ups And Downs Of Weight Cycling: How Fad Diets Can Negatively Affect Health, Catherine Jasper

BUHealth

It’s advice nearly every patient has heard at least once in their life: you need to lose weight. Often, this is prescribed as a combination of a healthy diet and exercise. However, ‘fad diets’, so-called due to their fluctuating popularity from societal trends, are seen as quick and easy diet modifications that produce weight loss quickly. For some, these diets are not sustainable and can lead to dangerous cycles of losing weight, easing restrictions, and re-gaining weight that was lost. Weight-cycling is a dangerous effect of fad diets, and the long-term physical and psychological effects of weight cycling can ultimately …

Resisting The Resistance: How The Environment Is Impacting Antibiotic Resistance, Hannah Hinrichs

BUHealth

Upon their discovery, antibiotics were known as “wonder drugs” due to their ability to cure serious bacterial infections. While antibiotics are still revolutionary in healthcare today, the emergence of antibiotic resistance is a growing threat to public health. Antibiotic resistance is simply a normal adaptive response where bacteria evolve over time. However, overuse of antibiotics, sub-optimal treatment regimens, and environmental exposures create optimal conditions for antibiotic resistance to develop and spread. Common ways antibiotics enter the environment are via wastewater and agricultural use. Even with properly functioning wastewater treatment systems, full removal of resistant bacteria may not be possible as …

You Are What You Eat, Allyson Ditmars

BUHealth

The gut microbiome is the wide array of good and bad bacteria found in the digestive tract of all humans. Although the composition of gut microbiota is developed before someone is even born, there are nutritional decisions made in adulthood that can impact the health of the gut. Certain nutritional foods can increase the diversity of the gut and create a beneficial environment. On the other hand, many foods found in the common American diet can negatively impact the microbiome. The gut can suffer from a poor diet when the permeability of the intestinal barrier and the diversity richness is …

A Natural Near-Infrared Fluorescent Probe For Cancer Cell Imaging, Benilde E. Adriano, Nycol M. Cotto, Neeraj Chauhan, Meena Jaggi, Subhash C. Chauhan, Murali M. Yallapu

Research Colloquium

Introduction: Near-Infrared (NIR) fluorescence-based imaging is a noteworthy and safer strategy for cancer cells/tissues imaging compared to radiological imaging. NIR fluorescence offers deep tissue penetration and have minimal obstruction by autofluorescence and photon scattering [1]. There are several NIR dyes including indocyanine green (ICG) [2] and IR-1061 [3] that allow high-resolution tissue imaging. However, these dyes possess some low-quality characteristics which limit their use, namely photo instability, toxicity, poor water solubility, and short half-lives [4]. Therefore, more efficient and effective alternatives are urgently required to provide the desired clinical outcomes. Chlorophyll (Chl) is a natural dietary NIR fluorescence emitting …

Development Of Targeted Drug Delivery System To Improve Immunotherapy In Pancreatic Cancer, Poornima Devi Shaji, Ana Martinez Bulnes, Nirnoy Dan, Subhash C. Chauhan, Sheema Khan, Murali M. Yallapu

Research Colloquium

Introduction: About 95% of tumor arises from epithelial cell lining ducts known to be pancreatic ductal adenocarcinomas, with less than 5-7% survival rate. Unfortunately, little progress has been seen in the outcomes of patients with PDAC as tumor develops high desmoplasia and chemo-resistance to chemotherapeutic drugs, such as gemcitabine (Gem). Immunotherapy has shown promising results in other cancers but limited response in pancreatic cancer due to desmoplasia and fibrotic tumor microenvironment. A recently identified mucin, MUC13 is aberrantly expressed in pancreatic tumors but not in normal pancreas. Due to its high membrane expression, MUC13 may serve as an excellent target …

Novel Therapy Targeting Mutant-Krasg12d And Galectin-1 In Pancreatic Cancer, Ana I. Martinez Bulnes, Nirnoy Dan, Poornima Devi Shaji, Swathi Holla, Murali M. Yallapu, Sheema Khan

Research Colloquium

Introduction: Although, surgical resection and chemotherapy are the gold standard for treating Pancreatic Ductal Adenocarcinoma (PDAC), low patient survival rate remains the problem. The activating point mutation of the KRAS on codon-12 is present in 70–95% of PDAC cases and so far, no success has been achieved to inhibit KRAS. KRASG12D regulates cell proliferation, differentiation, apoptosis. Recent preliminary and published studies show high Galectin-1 (Gal-1) levels in both pancreatic cancer and stromal cells, which modulate tumor microenvironment and metastasis. Additionally, genetic deletion of gal1 inhibits metastasis and improves survival in KRAS mouse model of PDAC (1). Therefore, our objective is …
