Generation And Characterization Of Peptide Fusion Proteins, Brianna L. Probasco

Graduate School of Biomedical Sciences Theses and Dissertations

Pathogenic Th17 cells drive progression of many autoimmune diseases. Th17 cells develop from naïve T cells in the immune system after antigen-driven stimulation in a specific cytokine environment. Normally, T cells act to fight off infection, but when not properly controlled, they can cause disease. The cytokine interleukin-23 (IL-23) plays an essential role in the expansion of pathogenic Th17 cells. IL-23 is a heterodimeric protein, composed of a p19 alpha chain and a p40 beta chain. The p40 is also part of IL-12 and binds to the IL-12 receptor beta 1 (IL-12Rβ1) subunit. Thus, it follows that the IL-23 receptor …

Understanding the interaction of anticancer drugs with model cell lines is important to elucidate the mode of action of these drugs as well as to develop cost effective and rapid screening methods. Raman spectroscopy has been demonstrated to be a valuable technique for high throughput, noninvasive analysis. The interaction of vincristine with a human lung adenocarcinoma cell line (A549)was investigated using Raman micro spectroscopy. The results were correlated with parallel measurements from the MTT cytotoxicity assay, which yielded an IC₅₀ value of 0.10 ± 0.03 μM. The Raman spectral data acquired from vincristine treated A549 cells was analysed to …

Efficacy Of Probiotics Lactobacillus Rhamnosus Gg And Saccharomyces Boulardii In The Treatment Of Antibiotic-Associated Diarrhea And Clostridium Diffiicile-Associated Disease, Estie Klugmann

The Science Journal of the Lander College of Arts and Sciences

Antibiotic therapy may cause serious side effects. Two disturbing effects of antibiotic administration are antibiotic-associated diarrhea and Clostridium difficile-associated disorder. Antibiotic-associated diarrhea occurs as a direct result of the normal flora destruction due to the antibiotics - which do not discriminate against pathogens or healthy forms of bacteria. C. diff disorder also occurs as an indirect result of antibiotic administration, because the destruction of the normal flora prevents people from having healthy bacteria to prevent disease. There have been studies conducted to determine if replacing the destroyed normal flora with probiotics, or beneficial microorganisms will prevent or treat these conditions. …

What Is The Role Of Incretin Mimetics In The Treatment Of Type 2 Diabetes?, Isaac Silberstein

The Science Journal of the Lander College of Arts and Sciences

Type 2 diabetes mellitus (DM) is an intricate disorder defined by insulin resistance, impaired insulin secretion, hyperglycemia, and both microvascular and macrovascular complications. Standard antidiabetic agents like metformin, insulin, sulfonylureas and thiazolidinediones are often insufficient at glucoregulation and do not address the decline in beta cell function that characterizes type 2 diabetes. Moreover, the adverse effects of some of these pharmaceuticals, such as hypoglycemia and weight gain, are disappointing and further limit their clinical utility. Research demonstrates that the actions of two potent incretins. Glucagon-like peptide 1 (GLP-1) and gastric inhibitory polypeptide (GIP), address these concerns as they stimulate beta …

Pilot Study Of A Kinect-Based Video Game To Improve Physical Therapy Treatment, Jacob Samuel Brown

Department of Computer Graphics Technology Degree Theses

Burnie is an exergame being developed at Purdue University and is used in this study. Burnie was developed using the Unity3D engine and OpenNI to interface with the Xbox Kinect. This study looked at how gesture intensity affected perceived enjoyment and perceived fatigue of the game. The results of the study could not reject the null hypothesis. Gesture intensity does not have a significant relationship to perceived enjoyment and perceived fatigue. This result means that future studies can alter the gesture intensity of the game Burnie without adversely affecting the player’s enjoyment and fatigue levels.

Impaired Skeletal Muscle Blood Flow Control With Advancing Age In Humans: Attenuated Atp Release And Local Vasodilation During Erythrocyte Deoxygenation, Brett S. Kirby, Anne R. Crecelius, Wyatt F. Voyles, Frank A. Dinenno

Health and Sport Science Faculty Publications

Rationale: Skeletal muscle blood flow is coupled with the oxygenation state of hemoglobin in young adults, whereby the erythrocyte functions as an oxygen sensor and releases ATP during deoxygenation to evoke vasodilation. Whether this function is impaired in humans of advanced age is unknown.

Objective: To test the hypothesis that older adults demonstrate impaired muscle blood flow and lower intravascular ATP during conditions of erythrocyte deoxygenation.

Methods and Results: We showed impaired forearm blood flow responses during 2 conditions of erythrocyte deoxygenation (systemic hypoxia and graded handgrip exercise) with age, which was caused by reduced local vasodilation. In young adults, …

Pharmacokinetics And Brain Uptake In The Rhesus Monkey Of A Fusion Protein Of Arylsulfatase A And A Monoclonal Antibody Against The Human Insulin Receptor, Ruben J. Boado, Jeff Zhiqiang Lu, Eric Ka-Wai Hui, Rachita K. Sumbria, William M. Pardridge

Pharmacy Faculty Articles and Research

Metachromatic leukodystrophy (MLD) is a lysosomal storage disorder of the brain caused by mutations in the gene encoding the lysosomal sulfatase, arylsulfatase A (ASA). It is not possible to treat the brain in MLD with recombinant ASA, because the enzyme does not cross the blood-brain barrier (BBB). In the present investigation, a BBB-penetrating IgG-ASA fusion protein is engineered and expressed, where the ASA monomer is fused to the carboxyl terminus of each heavy chain of an engineered monoclonal antibody (MAb) against the human insulin receptor (HIR). The HIRMAb crosses the BBB via receptor-mediated transport on the endogenous BBB insulin receptor, …

Muscle Contraction Duration And Fibre Recruitment Influence Blood Flow And Vo2 Independent Of Contractile Work During Steady-State Exercise In Humans, Jennifer C. Richards, Anne R. Crecelius, Brett S. Kirby, Dennis G. Larson, Frank A. Dinenno

Health and Sport Science Faculty Publications

We tested the hypothesis that, among conditions of matched contractile work, shorter contraction durations and greater muscle fibre recruitment result in augmented skeletal muscle blood flow and oxygen consumption (O2) during steady-state exercise in humans. To do so, we measured forearm blood flow (FBF; Doppler ultrasound) during 4 minutes of rhythmic handgrip exercise in 24 healthy young adults and calculated forearm O2 via blood samples obtained from a catheter placed in retrograde fashion into a deep vein draining the forearm muscle. In Protocol 1 (n = 11), subjects performed rhythmic isometric handgrip exercise at mild and moderate intensities under conditions …

Novel Use Of Dual Anti-Inflammatory Therapy To Overcome Drug Resistance And Improve Functional Recovery Following Spinal Cord Injury, Jennifer Dulin

Dissertations and Theses (Open Access)

Over 1.2 million Americans are currently living with a traumatic spinal cord injury (SCI). Despite the need for effective therapies, there are currently no proven effective treatments that can improve recovery of function in SCI patients. Many therapeutic compounds have shown promise in preclinical models of SCI, but all of these have fallen short in clinical trials.

P-glycoprotein (Pgp) is an active transporter expressed on capillary endothelial cell membranes at the blood-spinal cord barrier (BSCB). Pgp limits passive diffusion of blood-borne drugs into the CNS, by actively extruding drugs from the endothelial cell membrane. Pgp can become pathologically up-regulated, thus …

Connecting Cultures: Msmcbj’S Alternative Methods To Mental Health Therapy Within The Aldeia Indigenous Reserve And The Bom Jardim Favela, Emily Rasowsky

Independent Study Project (ISP) Collection

For my Independent Research Project I observed how community integration and connecting individuals back to the indigenous cultural idea of community work together to improve upon the mental health of individuals in the Favela of Bom Jardim, Fortaleza and the Pitaguary Indigenous Reserve or Aldeia. I examined how the Movimento de Saude Mental Comunitara do Bom Jardim (MSMCBJ) organization provides individuals within Bom Jardim a space to build a supportive community, based in indigenous ideals, while simultaneously providing professional and social opportunities for the Pitaguary tribe to create a sense of cultural valorization and how both of these aspects lead …
