Neuroimaging Strategies Addressing Challenges in Using fMRI for the Children with Cerebral Palsy  [PDF]
Juniper J. Lee-Park, Harshawardhan Deshpande, Jonathan Lisinski, Stephen LaConte, Sharon Ramey, Stephanie DeLuca
Journal of Behavioral and Brain Science (JBBS) , 2018, DOI: 10.4236/jbbs.2018.85019
Abstract: Aim: This study sought to develop a process and methodology that could be a useful clinical and research tool for successfully completing functional magnetic resonance imaging (fMRI) scanning in children with Cerebral Palsy. Method: Six children with CP (mean age of 8.83 years; five with spastic hemiplegia, one with spastic quadriplegia) and three children with typical development (mean age of 9.33 years) completed an fMRI scanning protocol that used real-time motion feedback as a means of minimizing head and trunk motion. Anatomical, resting-state, and motor-task scans were sequentially obtained from each subject. Precentral “hand-knob” regions were identified on the anatomical scan and served as seed regions to reveal the functional connectivity of each subject’s brain as associated with hand movement. Results: Real-time motion feedback aided children in successful completion of resting state scans. Functional connectivity and brain activity mapping were obtained based on anatomical landmarks, and laterality indices were developed based on the obtained functional-connectivity map to specify a dominant side of brain activity that was matched to a clinical profile, despite anatomical variations that occur with Cerebral Palsy. Interpretation: Real-time motion feedback and the development of laterality indices can improve the clinical and research utility of fMRI scanning. What this paper adds: 1) Presents a real-time imaging protocol for fMRI to help children complete scanning; 2) Presents an fMRI methodology to obtain laterality indices in the presence of abnormal anatomy; 3) Provides findings of LI that match clinical diagnosis.
Photo-Electrochemical Studies on TiO2-Doped Ce (III/IV) Oxides Nanoparticles in Aqueous Electrolytes  [PDF]

Materials Sciences and Applications (MSA) , 2013, DOI: 10.4236/msa.2013.410078

Photoelectrochemical studies on TiO2 doped with Ce2O3 or CeO2 took place in aqueous solutions of [Fe(CN)6]4- as the source of hydrated electrons. Our studies show that doping TiO2 with CeO2 gave better photocatalytic reduction of [Fe(CN)6]3- than TiO2 doped with Ce2O3. However the TiO2 assemblies doped with either Ce(III) or Ce(IV) oxides give less photochemical reduction of [Fe(CN)6]3- that the oxides of pure metals (Ti or Ce). In both cases a lowering of the band gaps of TiO2 was noticed. Immobilized TiO2 doped with Ce oxides on a FTO (Fluorine Ten Oxide) surface gave greater photocurrent with I

Photoelectrochemical Studies on High Specific Capacitance-Photoactive Interfaces Based on Poly 3,4- Ethylenedioxythiophene/Metal Oxides Assemblies  [PDF]
Kasem K. Kasem, William Bennett, Heather Ramey, Nick Daanen
Journal of Materials Science and Chemical Engineering (MSCE) , 2015, DOI: 10.4236/msce.2015.35010
Abstract: Inorganic/organic interfaces (IOI) consist of TiO2/PEDOT (poly 3,4-ethylenedioxythiophene) and [PMo12O40]3- or MoO3/PEDOT were subject to photoelectrochemical studies in both aqueous nanosuspensions and in thin solid films. The effects PEDOT modifier caused on the photoelectrochemical behavior of the IOI were investigated using [Fe(CN)6]4- as the photoactive hydrated electron donor agent. Results show that native PEDOT or PEDOT doped with MoO3 thin films increased charge storage capability evident by the high capacitive current. In the case of nano suspensions composed of TiO2/PEDOT the adsorption process of [Fe(CN)6]3- (photolysis product) control of the photoactivity outcome of the IOI assemblies. TiO2/PEDOT shows a lower heterogeneous photochemical response than native TiO2 in short term photolysis times. At longer photolysis times the IOI shows photoactivity greater than that of native TiO2. The interface activities were explained by analyzing the IOI junction characteristics, such as electron affinity, work function and hole/electrons barrier heights. The aqueous nano-systems retained moderate stability as indicated by the reproducibility of their photocatalytic activities. Both [Fe(CN)6]4-and PEDT contributed to the stability of native TiO2 surfaces.
Organizational health assessment: a Romania firm case study
Shaomin Huang,Gerald W. Ramey
Review of Economic and Business Studies (REBS) , 2008,
Abstract: Other than measuring units of output or profit to evaluate organization performance, this research develops a new assessment concept, organizational health. The survey of Work Environment Scale as the foundation data for the System-wide Interpretation of Health and Quality was used in this case study on a Romania firm. Structural measurement on organization effectiveness, leadership, and term work efficiency was conducted and further explained by three dimensional graphs with a weighted least squares method. The system-wide assessment shows multiple causalities among the endogenous variables.
China’s Healthcare Reform And Resources Redistribution: Lessons For Emerging Nations
Jia CUI,Shaomin HUANG,Gerald RAMEY
Review of Economic and Business Studies (REBS) , 2009,
Abstract: Following China’s recent economic growth and healthcare reform, medical services quickly merged into the market economy. The burden of healthcare expense on the Chinese people has become a serious political issue. This research project reviews the changes in health expenditures made during the last two decades. This paper explores the cause of this rapid change in the healthcare sector and analyzes the corresponding statistics during the entire economic reform period. In addition, the paper articulates that the lack of healthcare coverage existed even before the healthcare reform formally started. As a direct result of this reform, medical resources were quickly concentrated in urban hospitals and the individual out-of pocket expense as the share of total health expenditures sharply increased. Recommendations are made for further healthcare reform.
“Not in their right mind”: the relation of psychopathology to the quantity and quality of creative thought
Christopher H. Ramey,Evangelia G. Chrysikou
Frontiers in Psychology , 2014, DOI: 10.3389/fpsyg.2014.00835
Abstract: The empirical link between psychopathology and creativity is often correlational and fraught with suspiciously causal interpretations. In this paper, we review research in favor of the position that certain forms of psychopathology that profoundly affect the neural substrates for rule-based thought (e.g., schizophrenia, bipolar disorder) can significantly influence the quantity of creative production. Because highly productive individuals, irrespective of psychopathology, often produce work of greater quality, it seems that such an increase in the quantity of one’s output positively affects the likelihood of generating those statistically rare acts and achievements identified and celebrated as creative. We consider evidence that offers support for such a claim. In addition, we explore findings from neuroscience that can address how a neural mechanism, the flexibility of which relies on tradeoffs between rule-based (e.g., prefrontal cortex) and stimulus-based (e.g., sensorimotor cortex) brain regions, is influenced by psychopathology in ways that can alter dramatically the quantity and quality of creative output.
Primary CNS T-Cell Lymphoma: A Case Report on a Solitary Cerebellar Lesion and Review of Current Relevant Literature  [PDF]
Aden McLaughlin, Sharon Gabizon
Open Journal of Modern Neurosurgery (OJMN) , 2013, DOI: 10.4236/ojmn.2013.32004

Primary central nervous system lymphoma of T-cell lineage (PCNSTL) is an extremely rare entity, with relatively few cases reported in the literature. Presented here is a case of a 44-year-old, HIV negative woman found to have a solitary cerebellar lesion following presentation to the Emergency Department with a fall. The lesion responded to emergent dexamethasone and was followed with serial MRI imaging, which continued to show lesion regression. The lesion was shown to have recurred on MRI 14 months post-presentation and found to be T-cell lymphoma following immunophenotyping and TCR gene rearrangement studies of tissue specimen obtained via excisional biopsy.

Rural nurses’ perceptions of a volunteer program in an acute setting: Volunteers delivering person-centred care for patients with dementia and delirium  [PDF]

Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.41005

Community volunteers were recruited and trained to deliver person-centred care to patients with dementia or delirium in an acute hospital setting, in a small rural Australian hospital. The volunteer program was grounded in action research methodology, and modelled on a previous research project. As a form of evaluation, interviews were conducted with nursing staff eight weeks after implementation of the volunteer program to explore their opinions. Data were analysed through a collaborative process and findings revealed strong benefits from the perspectives of the nursing staff. These benefits included overall improved patient care and improved time management for nursing tasks.

Farming Not Alone: Farmville Play and the Implications on Social Capital  [PDF]

Social Networking (SN) , 2014, DOI: 10.4236/sn.2014.35028
Abstract: This study explored the relationship between Farmville play and social capital. The implications of social game play for players’ psychological wellness were also assessed. Using survey data collected from Farmville players in Taiwan, it was found that the intensity of Farmville play was positively associated with players’ perceived bridging and bonding social capital. The extent to which intensive Farmville play may lead to the psychological benefits of enhanced life satisfaction and reduced loneliness was discussed. In addition, players who tended to add unacquaintances were more likely to perform better than those who added people they knew. However, connecting with existing contacts through the game provides higher sense of bonding social capital. Implications on the concept of weak and strong ties were also discussed.
