Exercise And Ischemia-Activated Pathways In Limb Muscle Angiogenesis And Vascular Regeneration, Vihang A Narkar

Faculty, Staff and Student Publications

Exercise has a profound effect on cardiovascular disease, particularly through vascular remodeling and regeneration. Peripheral artery disease (PAD) is one such cardiovascular condition that benefits from regular exercise or rehabilitative physical therapy in terms of slowing the progression of disease and delaying amputations. Various rodent pre-clinical studies using models of PAD and exercise have shed light on molecular pathways of vascular regeneration. Here, I review key exercise-activated signaling pathways (nuclear receptors, kinases, and hypoxia inducible factors) in the skeletal muscle that drive paracrine regenerative angiogenesis. The rationale for highlighting the skeletal muscle is that it is the largest organ recruited …

Beyond Breathless: Unravelling The Enigma Of Pulmonary Arteriovenous Malformations, Sri Mounya Jampala, Jagadish Kumar K Dr., Manjunath V G, Nandish H R

Digital Journal of Clinical Medicine

Pulmonary Arteriovenous Malformations (AVMs) are abnormal connections between the pulmonary arteries and veins, leading to a direct shunting of blood without passing through the normal capillary bed. These AVMs can be associated with a rare genetic disorder called Hereditary Hemorrhagic Telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome. HHT is an autosomal dominant disorder characterized by the development of fragile telangiectasias in various organs, including the skin and mucous membranes. These telangiectasias are prone to bleeding, leading to recurrent nosebleeds and mucocutaneous bleeding. In patients with HHT, the most common site of AVMs is in the lungs.

The Trichobezoar Enigma: Untangling The Intricacies Of Rapunzel Syndrome, Debabrata Sahu, Dr Rajkishor Sahu

Digital Journal of Clinical Medicine

Rapunzel Syndrome is a rare manifestation of trichobezoar, characterized by the presence of hair strands extending beyond the stomach and into the duodenum. Trichobezoars typically develop in individuals with a history of trichotillomania, a compulsive behavioral disorder involving hair-pulling, combined with trichophagia, the ingestion of hair. While trichobezoars predominantly form within the stomach, their occurrence in the jejunum is infrequent. This condition is more commonly observed in adolescent females.

The formation of bezoars within the gastrointestinal tract is typically attributed to anatomical changes. However, in cases where no such anatomical abnormalities are present, psychiatric disorders like trichotillomania can lead to …

Digital Journal of Clinical Medicine

Dengue fever is an arboviral infection typically characterized by thrombocytopenia and hemoconcentration. However, hematological manifestations may differ in patients with underlying hemoglobinopathies. We report a case of 18-year-old female diagnosed with dengue fever (IgM ELISA positive), presented with persistent fever, vomiting, and myalgia. Laboratory evaluation revealed moderate microcytic anemia (Hb 9.7 g/dL, MCV 54.7 fL) with a low Mentzer index (8.7). High-performance liquid chromatography confirmed β-thalassemia trait (HbA2 4.6%). Contrary to the typical presentation of dengue, the patient had elevated platelet counts at admission (584,000/µL), which remained within normal to high range during hospitalization. This case highlights that dengue infection …

Characterization And Investigation Of Cold Atmospheric Plasma And Its Effects On Cancer Cell Biology, Thomas M. Ritrosky

Theses and Dissertations

Modern cancer treatment uses radiation therapy in over 50% of patient cases. It is an e↵ective way of treating tumors because the mechanisms of cell killing are well known through the damage that ionizing radiation does to DNA. The amount of radiation can be tracked through measuring the dose of the clinical photon or electron beam used. However, there are limitations in the usage of radiation therapy, for example, a tumor can create hypoxic areas that become radioresistant leading to complete ine↵ectiveness of further radiation treatment. This project looks into the application of cold atmospheric plasma as an adjuvant therapy …

Development Of A Chemical Biology Approach To Uncover The Influence Of Sequence Variations On Ces1 Activity In Live Cells, Samuel James Knebel

Masters Theses

Drug metabolism is the biochemical process of modifying drugs to detoxify and remove them through enzymatic transformations. These biotransformation’s occur primarily in the liver and are critical to understanding how pharmaceutical compounds are chemically altered inside the human body. Human carboxylesterases (CESs) catalyze the hydrolysis of esters, amides, thioesters, and carbamates. CES-mediated hydrolysis plays an important role in the metabolism of many drugs including the first FDA approved antiviral treatment for COVID-19, remdesivir (Veklury), the seizure control medication rufinamide (Banzel), and the flu antiviral drug oseltamivir (Tamiflu). CES activity is known to be influenced by a variety of factors including …

Combining Mek And Src Inhibitors For Treatment Of Colorectal Cancer Demonstrate Increased Efficacy In Vitro But Not In Vivo, Fan Fan, Susmita Ghosh, Reid Powell, Jason Roszik, Yongsun Park, Mary Sobieski, Alexey Sorokin, Clifford Stephan, Scott Kopetz, Lee M Ellis, Rajat Bhattacharya

Faculty, Staff and Student Publications

Metastatic colorectal cancer (mCRC) is the second leading cause of cancer deaths in the United States. More than 50% of patients with mCRC harbor mutations of the oncogenic driver RAS (KRAS or NRAS). Because directly targeting most mutations of RAS is technically challenging, researchers have concentrated on targeting MEK, a downstream mediator of RAS. However, targeting MEK as single-agent therapy is ineffective in patients with mCRC. We hypothesize that combining a MEK inhibitor with other agents can enhance the efficacy of MEK targeting in mCRC. Unbiased high-throughput screening (HTS) was performed to identify drugs that enhance the efficacy of MEK …
