Studies Of Amino Acid Mutations In Drug Resistance Of The Smo Protein, Eunice Wintona 2018 University of Nebraska at Omaha

Studies Of Amino Acid Mutations In Drug Resistance Of The Smo Protein, Eunice Wintona

Student Research and Creative Activity Fair

Smoothened receptor (SMO) is a protein that in humans, is encoded by the SMO gene. A systemic mutation in its binding pocket helps predict the sensitivity of mutant proteins to different drugs. Known as a GPCR-like receptor, it is a component of the hedgehog signaling pathway; a pathway involved in body patterning and the regulation of adult stem cells. An uncontrolled or inappropriate activation of the Hedgehog pathway drives tumor progression in cancers and a number of birth defects. To achieve these goals, the molecular modeling software MOE was used to build small molecules and drug molecules like Vismodegib and ...

Profile Of Dupilumab And Its Potential In The Treatment Of Inadequately Controlled Moderate-To-Severe Atopic Dermatitis., Olabola Awosika, Lori Kim, Momina Mazhar, Monica Rengifo-Pardo, Alison Ehrlich

Dermatology Faculty Publications

Atopic dermatitis (AD) is a common inflammatory skin disorder that manifests as eczematous lesions, often associated with allergic rhinitis and asthma. Historically, moderate-to-severe disease has been managed with systemic immunosuppression, such as oral corticosteroids, which result in relapse and limiting side effects. Due to recent advancements in the identification of interleukin (IL)-4 and IL-13 as key mediators in AD, new biological agents have been developed for treatment. Dupilumab is a recently approved monoclonal antibody that targets the alpha subunit of the IL-4 receptor and, thus, downregulates activity of IL-4 and IL-13. This review discusses the profile of dupilumab and ...


Halting Progression Of Stasis Dermatitis: Community Perspectives And Strategies For Prevention, Allison B. Robbins 2018 University of Vermont

Halting Progression Of Stasis Dermatitis: Community Perspectives And Strategies For Prevention, Allison B. Robbins

Family Medicine Clerkship Student Projects

Complications of stasis dermatitis including venous ulcers, osteomyelitis, and cellulitis all significantly increase morbidity and mortality of disease. Progression beyond stasis dermatitis and avoidance of the aforementioned complications are preventable with patient education and adherence to basic therapies including compression stockings and lifestyle modification. Therefore the goals of this project were to: assess the community’s understanding of stasis dermatitis and their awareness of its complications; use this information to help healthcare providers tailor their preventative health counseling accordingly; and provide education for patients on stasis dermatitis, its complications, and therapies/behavioral changes to prevent disease progression.

Integrative Cancer Immunogenomic Analysis Of Serial Melanoma Biopsies Reveals Correlates Of Response And Resistance To Sequential Ctla-4 And Pd-1 Blockade Treatment, Whijae Roh

UT GSBS Dissertations and Theses (Open Access)

Melanoma is the most malignant form of skin cancer. The five-year survival rate for metastatic melanoma is 19.9%. Although targeted therapy of BRAF and MEK inhibitors were developed for melanoma, resistance to therapy is inevitable. Immune checkpoint blockade, which reverses the suppression of the immune system, on the other hand, has shown a durable response in 20-30% of patients with metastatic melanoma. However, more predictive and robust biomarkers of response to this therapy are still needed, and resistance mechanisms remain incompletely understood. To address this, we examined a cohort of metastatic melanoma patients treated with sequential checkpoint blockade against ...

Acute Bacterial Cellulitis: Emergency Department Management, Aetiological Epidemiology And Clinical Risk Factors For Antibiotic Treatment Failure, Michael Quirke

MD theses

This thesis consists of 6 work-packages (WPs) that describe the Emergency Department (ED) management of cellulitis; it’s aetiological epidemiology, and risk factors for antibiotic treatment failure.

In order to provide a context for this thesis, I performed a scientometric analysis of research output related to skin and soft tissue infections (SSTIs) between 1945 and 2014. Overall, research output was low but increased as a result of the community associated methicillin-resistant Staphylococcus aureus (CA-MRSA) epidemic in North American settings.

My observational research work began with two studies describing the ED incidence of cellulitis, antibiotic prescribing practices and physician adherence to ...

Cytosolic DNA-sensing pathways that signal via Stimulator of interferon genes (STING) mediate immunity to pathogens and also promote autoimmune pathology in DNaseII- and DNaseIII-deficient mice. In contrast, we report here that STING potently suppresses inflammation in a model of systemic lupus erythematosus (SLE). Lymphoid hypertrophy, autoantibody production, serum cytokine levels, and other indicators of immune activation were markedly increased in STING-deficient autoimmune-prone mice compared with STING-sufficient littermates. As a result, STING-deficient autoimmune-prone mice had significantly shorter lifespans than controls. Importantly, Toll-like receptor (TLR)-dependent systemic inflammation during 2,6,10,14-tetramethylpentadecane (TMPD)-mediated peritonitis was similarly aggravated in STING-deficient mice ...

Fungal Infections From Human And Animal Contact, Dennis J. Baumgardner 2017 Aurora UW Medical Group, Aurora Health Care; University of Wisconsin School of Medicine and Public Health; Center for Urban Population Health

Fungal Infections From Human And Animal Contact, Dennis J. Baumgardner

Dennis J. Baumgardner. MD

Fungal infections in humans resulting from human or animal contact are relatively uncommon, but they include a significant proportion of dermatophyte infections. Some of the most commonly encountered diseases of the integument are dermatomycoses. Human or animal contact may be the source of all types of tinea infections, occasional candidal infections, and some other types of superficial or deep fungal infections. This narrative review focuses on the epidemiology, clinical features, diagnosis and treatment of anthropophilic dermatophyte infections primarily found in North America. Other human-acquired and zoonotic fungal infections also are discussed in brief.


Identification And Phenotypic Plasticity Of Metastatic Cells In A Mouse Model Of Melanoma, Xiaoshuang Li 2017 Florida International University

Identification And Phenotypic Plasticity Of Metastatic Cells In A Mouse Model Of Melanoma, Xiaoshuang Li

FIU Electronic Theses and Dissertations

Melanoma is the deadliest form of skin cancer due to its high propensity to metastasize and resistance to current therapies. We have created a spontaneous mouse model of metastatic melanoma (Dct-Grm1/K5-Edn3) where metastasis to the lungs is 80% penetrant. The primary tumors of these mice present cellular heterogeneity with cells at varying levels of differentiation. The main goal of this study was to determine the metastatic potential of the primary tumor resident Tyrosinase positive cells and evaluate the dynamic phenotypic changes as those cells move from the primary tumors to the sites of metastasis. To accomplish this aim I ...
