The Design Of An Instrument To Assess Clinical Laboratories Efficacy Post Implementation Of The Patient Protection Affordable Care Act, Harry McDonald Jr. 2017 University of Southern Mississippi

The Design Of An Instrument To Assess Clinical Laboratories Efficacy Post Implementation Of The Patient Protection Affordable Care Act, Harry Mcdonald Jr.

Dissertations

The healthcare system in the United States has undergone substantial changes in support of the Patient Protection and Affordable Care Act (PPACA). On March 23, 2010, the implementation of the new healthcare law brought universal healthcare access to all Americans, while attempting to increase quality and decrease medical costs. The new law promotes more of a quality-focused, outcome-based model rather than a pay-for-fee service model; thus, moving the paradigm from infrequent to preemptive healthcare. The PPACA postulates as the only way to achieve cost savings while increasing quality and access. Never before has there been such an extensive change to ...


Stem Cell Derived Osteoprogenitors And Their Role In Bone Repair Using Morphogenic Activators, Angelina Miller, Sylvanna Islas, George Washington Brownridge III, Warren Hoeffler 2017 Dominican University of California

Stem Cell Derived Osteoprogenitors And Their Role In Bone Repair Using Morphogenic Activators, Angelina Miller, Sylvanna Islas, George Washington Brownridge Iii, Warren Hoeffler

Scholarly & Creative Works Conference 2017

Bone constantly cycles through a dynamic process of breakdown and remodeling. Osteoblasts are the specialized mesenchymal stem cells that have a major role in bone formation and the remodeling process whereas their counterpart osteoclasts, handle bone resorption. Embryonic stem cells can be partially differentiated into Progenitor cells, and we worked with #18, a candidate for being an osteoprogenitor that has the potential to respond to morphogenic activators. In the case of bone remodeling, TGF-β 2, BMP-2 and an abundance of CA++ have been shown to be potential activators of differentiation into osteoblasts. Eight different trials were conducted with the cells ...

The Research and Scholarship Symposium

Background

A rise in new schools of pharmacy has led to implementation of new curriculums. Pharmacy schools must adhere to standards set by the Accreditation Council of Pharmacy Education in order to provide knowledge of foundational sciences and prepare pharmacy students for the future. Prerequisites are typically foundational science courses taken early in the program so that students have the knowledge necessary to be excellent pharmacists. Within the Cedarville University School of Pharmacy, Biochemistry is a prerequisite course for Integrated Medicinal Chemistry and Pharmacology (PCoMedChem).

Objectives

The goal of this study is to determine if Biochemistry should remain a prerequisite ...


The Effect Of Photoactivated Tmp On Burkholderia Cepacia Biofilms, Reyna G. Osorio, Chandra N. Swiech, Tracy L. Collins 2017 Cedarville University

The Effect Of Photoactivated Tmp On Burkholderia Cepacia Biofilms, Reyna G. Osorio, Chandra N. Swiech, Tracy L. Collins

The Research and Scholarship Symposium

Burkholderia cepacia is an opportunistic pathogen that causes infections in immunocompromised individuals such as cystic fibrosis patients. B. cepacia infections are typically characterized by the formation of complex communities of cells known as biofilms. Because B. cepacia biofilms are difficult to eradicate using antibiotics, it is important to pursue alternative treatment methods. Photodynamic therapy (PDT) is a type of therapy that uses light, a photosensitizer, and oxygen to elicit cell death through the production of reactive oxygen species. PDT has been shown in previous studies to be successful in killing both Pseudomonas aeruginosa and Staphylococcus aureus. In this study, we ...


Lysine Residues Of Interferon Regulatory Factor 7 Affect The Replication And Transcription Activatormediated Lytic Replication Of Kaposi’S Sarcomaassociated Herpesvirus/Human Herpesvirus 8, Tianzheng Zhang, Ying Wang, Li Zhang, Bin Liu, Jinhui Xie, Charles Wood, Jinzhong Wang 2017 Nankai University

Lysine Residues Of Interferon Regulatory Factor 7 Affect The Replication And Transcription Activatormediated Lytic Replication Of Kaposi’S Sarcomaassociated Herpesvirus/Human Herpesvirus 8, Tianzheng Zhang, Ying Wang, Li Zhang, Bin Liu, Jinhui Xie, Charles Wood, Jinzhong Wang

Virology Papers

Kaposi’s sarcoma-associated herpesvirus (KSHV) infection goes through latent and lytic phases, which are controlled by the viral replication and transcription activator (RTA). Upon KSHV infection, the host responds by suppressing RTA-activated lytic gene expression through interferon regulatory factor 7 (IRF-7), a key regulator of host innate immune response. Lysine residues are potential sites for post-translational modification of IRF-7, and were suggested to be critical for its activity. In this study, we analysed the 15 lysine residues for their effects on IRF-7 function by site-directed mutagenesis. We found that some mutations affect the ability of IRF-7 to activate interferon (IFN ...

Dugoni School of Dentistry Faculty Articles

Research on human immunology has been hindered by the lack of optimal small animal models, given that the protective immune responses of human and non-human species show significant differences. However, due to ethical constraints[1] and the high cost of clinical trials, it is urgent to improve the current animal models that can mimic faithfully human physiology, particularly the human immune system (HIS). HIS mice had been generated recently by engrafting human hematopoietic stem cells (hHSCs) or human peripheral mononuclear cells (hPBMCs) into highly immuno-deficient mice such as NSG, NOG or NRG mice. However, a major experimental drawback for studies ...


The Use Of Rhyme, Rhythm, And Melody As A Form Of Repetition Priming To Aid In Encoding, Storage, And Retrieval Of Semantic Memories In Alzheimer’S Patients, Faiz Plastikwala 2017 Virginia Commonwealth University

The Use Of Rhyme, Rhythm, And Melody As A Form Of Repetition Priming To Aid In Encoding, Storage, And Retrieval Of Semantic Memories In Alzheimer’S Patients, Faiz Plastikwala

Virginias Collegiate Honors Council Conference

Treating Alzheimer’s disease, especially through non-pharmaceutical means, has become increasingly important over the past few decades. I examined the use of melody, rhyme, and rhythm as encoding mechanisms to aid in the retrieval of long term semantic information by juxtaposing previous experiments in the field. Melody, rhyme, and rhythm provide an organizational structure to facilitate the encoding of information. Specifically, chunking, the grouping of smaller units into larger ‘chunks’, helps facilitate long term encoding in patients, and is the byproduct of the organizational structure of a text. A major drawback of using these devices is the loss in the ...


Therapeutic Application Of Carbon Monoxide In Acute Limb Compartment Syndrome, Aurelia Bihari 2017 The University of Western Ontario

Therapeutic Application Of Carbon Monoxide In Acute Limb Compartment Syndrome, Aurelia Bihari

Electronic Thesis and Dissertation Repository

Acute limb compartment syndrome (CS), a devastating complication of musculoskeletal trauma, develops in response to elevation of the pressure within a closed osseofascial compartment, producing muscle- and limb-threatening ischemia. Full decompression of all involved compartments by fasciotomy is the current gold-standard therapy, but it must be performed within a surgical window of 6-8 hours, before tissue damage becomes permanent.

Carbon monoxide (CO), a byproduct of heme metabolism, has been shown protective in ischemia. While inhalation of CO leads to elevation of carboxyhemoglobin (COHb), recent development of transitional metal carbonyls, CO-releasing molecules (CO-RMs), particularly the water-soluble CORM-3, delivers CO in a ...

A Few Notes On Nabokov's Childhood Entomology, Victor Fet 2017 Marshall University

A Few Notes On Nabokov's Childhood Entomology, Victor Fet

Victor Fet

Nabokov's lepidoptery long posed a question: Was he an amateur or a professional entomologist? Today, it has been amply demonstrated that he was a professional. Kurt Johnson says, "For Nabokov, as with many, fascination with the big picture books of butterflies as a young child grew to concerted collecting as a youngster. As with many scientists, these impressions of youth become a driving life force."3 Nabokov started collecting butterflies in 1906, at age seven, and never ceased; he published his first book of poems ten years later, at age seventeen; his first research paper on butterflies, at age ...


Antitumor Activity Of Selected Derivatives Of Pyrazole- Benzenesulfonamides From Dilithiated C(Α), N-Phenylhydrazones And Lithiated Methyl 2-(Aminosulfonyl)Benzoate, N. Dwight Camper [deceased], James M. Gum, Darby E. Lyles, William T. Pennington, Charles F. Beam, Clyde R. Metz 2017 Clemson University

Antitumor Activity Of Selected Derivatives Of Pyrazole- Benzenesulfonamides From Dilithiated C(Α), N-Phenylhydrazones And Lithiated Methyl 2-(Aminosulfonyl)Benzoate, N. Dwight Camper [Deceased], James M. Gum, Darby E. Lyles, William T. Pennington, Charles F. Beam, Clyde R. Metz

Journal of the South Carolina Academy of Science

Several pyrazole-benzenesulfonamides were subjected to biological evaluation involving tumor formation on potato discs caused by Agrobacterium tumefaciens. This assay led to some excellent and promising initial results with three of the pyrazole compounds showing increased tumor inhibition when compared to a recognized standard, camptothecin. The select pyrazole-benzenesulfonamides were prepared by condensation-cyclization of several dilithiated C(α),N-phenylhydrazones with lithiated methyl 2-aminosulfonyl-benzoate.


The Effects Of Previous Concussions On The Physiological Complexity Of Motor Output During A Continuous Isometric Visual-Motor Tracking Task, Adam C. Raikes 2017 Utah State University

The Effects Of Previous Concussions On The Physiological Complexity Of Motor Output During A Continuous Isometric Visual-Motor Tracking Task, Adam C. Raikes

All Graduate Theses and Dissertations

The majority of clinical impairments following a concussion resolve within 7-10 days. However, there is limited clarity as to long-term impact of this injury on neurocognitive function, motor control, and particularly integration of these domains. While repetitive head trauma is associated with numerous neurological disorders, the link is not well described. Visual-motor tracking tasks have been used to identify differences in visual processing, error detection, and fine motor control in aging and numerous pathologies. Examining the complexity of motor output from visual-motor tracking provides insight into multiple cognitive and motor function domains, and into fine motor control used for daily ...


Personality Disorders And Epigenetics, Julie Zaccagnino 2017 Germanna Community College

Personality Disorders And Epigenetics, Julie Zaccagnino

Student Writing

Personality Disorders are characterized by chronic and pervasive maladaptive patterns which cause emotional distress to the individual, his/her relationships, and society. The purpose of analysis is to understand the causes of personality disorders. Genetic influence on personality is not a simple cause-and-effect. Several genes have been identified to be associated with personality traits but not cause personality traits. Personality disorders have been also associated with childhood trauma. Evidence in research has shown that childhood maltreatment is marked by DNA methylation of genes which promote glucocorticoid receptors in the synapses of the hippocampus and as well as serotonergic pathways. The ...

Molecular Medicine Articles

The K+ channel KCNQ1 has been proposed as a tumor suppressor in colorectal cancer (CRC). We investigated the molecular mechanisms regulating KCNQ1:β-catenin bidirectional interactions and their effects on CRC differentiation, proliferation, and invasion. Molecular and pharmacologic approaches were used to determine the influence of KCNQ1 expression on the Wnt/β-catenin signaling and epithelial-to-mesenchymal transition (EMT) in human CRC cell lines of varying stages of differentiation. The expression of KCNQ1 was lost with increasing mesenchymal phenotype in poorly differentiated CRC cell lines as a consequence of repression of the KCNQ1 promoter by β-catenin:T-cell factor (TCF)-4. In welldifferentiated epithelial ...

Natural Killer (Nk) Cells And Their Involvement In Different Types Of Cancer. Current Status Of Clinical Research, Isadora Zaharescu, Adina D. Moldovan, Cristiana Tanase

Journal of Mind and Medical Sciences

Natural killer cells are the main agents of innate immunity. Since 1970, various studies have repeatedly confirmed their involvement in decreasing local tumor growth and also decreasing the risk of metastasis, due to their cytotoxic effects and also through the release of immunostimulatory cytokines such as IFN-gamma. In the 1990s, several studies demonstrated the existence of certain inhibiting and stimulating receptors of these cells, leading to the concept of “induced self”, thus explaining why tumors with MHC-1 are destroyed and autologous cells without it are saved out. Recognition and destruction of tumor cells by the NK cells are the result ...
