Measuring Pacemaker Dose: A Clinical Perspective, M. Studenski, Y. Xiao, A. Harrison Dec 2010

Measuring Pacemaker Dose: A Clinical Perspective, M. Studenski, Y. Xiao, A. Harrison

Bodine Journal

Purpose: The number of patients presenting with pacemakers in our clinic has increased recently. Following AAPM recommendations, a treatment plan is developed that minimizes the dose to the pacemaker. The most efficient way to measure in vivo dose during treatment is to use MOSFETs or diodes which offer a simple but inaccurate (up to 25% error) method of recording. In this abstract, we analyze the dose measured by these different devices in an attempt to assess pacemaker dose.

Combination Of Vorinostat With Whole-Brain Radiotherapy In The Treatment Of Brain Metastases, Y. R. Lawrence, R. M. Pfeffer, M. Werner-Wasik, H. Choy, A. Dicker Dec 2010

Combination Of Vorinostat With Whole-Brain Radiotherapy In The Treatment Of Brain Metastases, Y. R. Lawrence, R. M. Pfeffer, M. Werner-Wasik, H. Choy, A. Dicker

Bodine Journal

Background: A third of patients with solid malignancies develop brain metastases. Expected overall survival is 4-7 months depending on age, performance status, and extracranial disease. Standard treatment is controversial; however, the majority of patients receive wholebrain radiation therapy at some point. Vorinostat (suberoylanilide hydroxamic acid, SAHA), an FDA-approved HDAC inhibitor, has been demonstrated to radiosensitize tumor cells in vitro, as assessed by both radiation-induced DNA damage and clonogenic cell survival (Munshi et al. Molecular Cancer Therapeutics 5, 1967-1974, 2006). We have shown that vorinostat downregulates key genes involved in double-strand DNA repair (Rad50, Rad51, XRCC2, XRCC3, XRCC6), as assessed by …


Accuracy Of Cancer Information On The Internet: A Comparison Of A Wiki With A Professionally Maintained Database, M. S. Rajagopalan, V. Khanna, M. Stott, Y. Leiter, T. N. Showalter, A. Dicker, Y. L. Lawrence Dec 2010

Accuracy Of Cancer Information On The Internet: A Comparison Of A Wiki With A Professionally Maintained Database, M. S. Rajagopalan, V. Khanna, M. Stott, Y. Leiter, T. N. Showalter, A. Dicker, Y. L. Lawrence

Bodine Journal

Background: A Wiki is a website which can be directly, openly edited; Wikipedia, a collaborative encyclopedia, is a well-known example. Due to Wiki’s lack of editorial control and formal structure, we hypothesized that the content would be less complete and less accurate than that presented on a formal, peer-reviewed web site. Our goal was to compare the coverage, accuracy, and readability of cancer information from a Wiki (Wikipedia) with a peer-reviewed web site, the patientoriented National Cancer Institute’s Physician Data Query (PDQ) comprehensive cancer database.

Potential For Thermal Enhancement By Quercetin Mediated Mechanisms Targeting P53 Antagonists In Human Melanoma Cells, T. Thangasamy, K. Limesand, D. B. Leeper, R. Burd Dec 2010

Potential For Thermal Enhancement By Quercetin Mediated Mechanisms Targeting P53 Antagonists In Human Melanoma Cells, T. Thangasamy, K. Limesand, D. B. Leeper, R. Burd

Bodine Journal

Introduction: Recently Temozolomide (TMZ) has become the more commonly used analog of DTIC-related oral agents. Although the response rates achieved by TMZ alone are less than satisfactory, there is great interest in identifying compounds that could be used in combination therapy. We have previously demonstrated that the bioflavonoid quercetin (Qct) promotes a p53-mediated response in melanoma and sensitizes melanoma to DTIC. Here we demonstrate that Qct also sensitizes cells to TMZ by a mechanism that involves the modulation of a truncated p53 family member, ΔNp73.

Control Of Glycolytic Flux By Ampk And P53-Mediated Signaling Pathways In Tumor Cells Adapted To Grow At Low Ph, E. E. Mendoza, J. Caro, D. B. Leeper, R. Burd Dec 2010

Control Of Glycolytic Flux By Ampk And P53-Mediated Signaling Pathways In Tumor Cells Adapted To Grow At Low Ph, E. E. Mendoza, J. Caro, D. B. Leeper, R. Burd

Bodine Journal

Introduction: Tumor cells grow in nutrient and oxygen deprived microenvironments and adapt to the suboptimal growth conditions by altering metabolic pathways. This adaptation process characteristically results in a tumor phenotype that displays anaerobic glycolysis, chronic acidification and aggressive tumor characteristics. Understanding the tumor cell reaction to the microenvironment is a critical factor in predicting the tumor response to hyperthermia. The glucose regulatory molecule, 6-Phosphofructo-2-Kinase/Fructose-2,6-Biphosphatase Isoform-3 (PFKFB3), is a bifunctional enzyme central to glycolytic flux and downstream of the metabolic stress sensor AMP-activated protein kinase (AMPK), which has been shown to activate an isoform of Phosphofructokinase (PFK-2).

Functional Antagonism Between Vorinostat And Temozolomide When Combined With Ionizing Radiation (Ir) In Glioblastoma, Y. R. Lawrence, Y. Liu, B. Andersen, X. Xia, A. P. Dicker, P. Wachsberger Dec 2010

Functional Antagonism Between Vorinostat And Temozolomide When Combined With Ionizing Radiation (Ir) In Glioblastoma, Y. R. Lawrence, Y. Liu, B. Andersen, X. Xia, A. P. Dicker, P. Wachsberger

Bodine Journal

Background: Glioblastoma is the most common primary adult brain tumor. Surgery followed by radiation therapy in combination with temozolomide (Tmz) produces a median survival of 14.6 months. Tmz is a DNA akylating agent that leads to the mispairing of guanine residues with thymine. An intact mismatch-repair mechanism (MMR) converts the mispaired thymine into a lethal double-strand DNA break. Vorinostat (SAHA), an HDAC inhibitor, has been shown to act as a radiosensitizer, possibly through inhibition of DNA repair. SAHA has successfully been combined with a number of cytotoxic agents. We hypothesized that SAHA would further potentiate the radiosensitizing properties of Tmz …

Quintessential Acts Of Inquiry In Educational Practice: Delineating Inquiry And Interpretation In The Pursuit Of Teacher Professionalization, Ted Purinton Dec 2010

Quintessential Acts Of Inquiry In Educational Practice: Delineating Inquiry And Interpretation In The Pursuit Of Teacher Professionalization, Ted Purinton

i.e.: inquiry in education

Sociological and political theories on the professions indicate that established professions utilize unique forms of inquiry and interpretation to guide practice. This essay argues that for teaching to become professionalized, unique forms of inquiry and interpretation need to be emphasized. Utilizing the concept of professional jurisdiction, the essay argues that other professions' forms of inquiry, while not detrimental to the purpose of teacher professionalization, do not establish the distinctive skills upon which teachers can lay claim.

ServDes Conference Series

The growing complexity of societal problems and the increasing need to co-design contexts together with the service or product; force companies to collaborate in innovation. This networked innovation requires people to design together; who not only come from different disciplines; but also come from different organisations and companies. The collaboration in networked innovation therefore adds another level of complexity in addition to the (better known) collaboration in mono- and multidisciplinary teams and introduces new issues.

Characteristics Of Value Co-Creation In A Learning Environment By Service Design And Service-Dominant Logic Frameworks, Jussi Haukkamaa, Pia Yliräisänen-Seppänen, Eija Timonen

ServDes Conference Series

Presently; educational institutions exist as complex networks of expertise that fulfil the needs of their stakeholders and respond to the challenges of a transforming society. Therefore; educational services are subject to a constant design process in co-operation with the customers and other stakeholders. Co-operation between parties is strongly related to the value co-creation; since the customer is the co-producer of the value according to the concept of service-dominant logic.

Service design research has paid little attention to the value of co-creation in networked education services. This paper focuses on value co-creation in service-dominant logic and service design frameworks using a …


Transformative Services And Transformation Design, Daniela Sangiorgi Dec 2010

Transformative Services And Transformation Design, Daniela Sangiorgi

ServDes Conference Series

This paper claims how the parallel evolution of the conception of services and of Design for Services toward more transformational aims; would require a collective reflection on and elaboration of guiding methodological and deontological principles. By illustrating connections with similar evolutions in Participatory Design (from ‘Design for use before use’ to ‘Design for Design after Design’); Public Health Research (patient engagement and ‘empowerment’) and Consumer Research (Transformative Consumer Research); the author identifies key characteristics of transformative practices that ask for more ‘reflexivity’ on the designers’ side. Developing Design profession as contributing to society transformative aims is extremely valuable; but it …
