Striatal Glutamate Release In L-Dopa-Induced Dyskinetic Animals, Nina Nevalainen, Martin Lundblad, Greg A. Gerhardt, Ingrid Strömberg

Neuroscience Faculty Publications

L-DOPA-induced dyskinesia is a common side effect developed after chronic treatment with 3,4-dihydroxyphenyl-l-alanine (l-DOPA) in Parkinson's disease. The biological mechanisms behind this side effect are not fully comprehended although involvement of dopaminergic, serotonergic, and glutamatergic systems has been suggested. The present study utilizes in vivo amperometry to investigate the impact from unilateral 6-hydroxydopamine lesions and l-DOPA (4 mg/kg, including benserazide 15 mg/kg) -induced dyskinetic behavior on striatal basal extracellular glutamate concentration and potassium-evoked glutamate release in urethane-anesthetized rats. Recordings were performed before and after local L-DOPA application in the striatum. In addition, effects from the 5-HT_1A receptor agonist (2R)-(+)-8-hydroxy-2-(di-n-propylamino)tetralin …

Clobazam Therapeutic Drug Monitoring: A Comprehensive Review Of The Literature With Proposals To Improve Future Studies, Jose De Leon, Edoardo Spina, Francisco J. Diaz

Psychiatry Faculty Publications

Background: Clobazam was recently approved for Lennox–Gastaut syndrome in the United States. There is no published review article focused on clobazam therapeutic drug monitoring (TDM) in English.

Methods: More than 200 clobazam articles identified by a PubMed search were carefully reviewed for information on clobazam pharmacokinetics. Clobazam is mainly metabolized by a cytochrome P450 (CYP) isoenzyme, CYP3A4, to its active metabolite, N-desmethylclobazam. Then, N-desmethylclobazam is mainly metabolized by CYP2C19 unless the individual has no CYP2C19 activity [poor metabolizer (PM)].

Results: Using a mechanistic approach to reinterpret the published findings of steady-state TDM and single-dosing pharmacokinetic studies, 4 different serum clobazam …

The Feasibility Of A Fiber Optic Laser Approach To Relieving Lymphedematous Syndrome: A Case Report, Beniamino Palmieri, Alessandro Di Cerbo, Valentina Rottigni, Gregorio Fistetto, Tommaso Iannitti

Physiology Faculty Publications

Here we report a case of successful fiber optic laser treatment of lymphedema in a swollen arm post mastectomy. At the moment, this procedure has only anecdotal evidence to justify its use, but in our experience is a feasible, minimally invasive day-stay procedure which has been demonstrated to be safe and effective. Further nonhomogeneous case pooling and follow-up would enable guidelines and definite surgical protocols for its use to be implemented.

Changes In Bacterial Growth Rate Govern Expression Of The Borrelia Burgdorferi Ospc And Erp Infection-Associated Surface Proteins, Brandon L. Jutras, Alicia M. Chenail, Brian Stevenson

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The Lyme disease spirochete controls production of its OspC and Erp outer surface proteins, repressing protein synthesis during colonization of vector ticks but increasing expression when those ticks feed on vertebrate hosts. Early studies found that the synthesis of OspC and Erps can be stimulated in culture by shifting the temperature from 23°C to 34°C, leading to a hypothesis that Borrelia burgdorferi senses environmental temperature to determine its location in the tick-mammal infectious cycle. However, borreliae cultured at 34°C divide several times faster than do those cultured at 23°C. We developed methods that disassociate bacterial growth rate and temperature, allowing …

Pharmacology and Nutritional Sciences Faculty Publications

Despite advances in cancer detection and prevention, a diagnosis of metastatic disease remains a death sentence due to the fact that many cancers are either resistant to chemotherapy (conventional or targeted) or develop resistance during treatment, and residual chemoresistant cells are highly metastatic. Metastatic cancer cells resist the effects of chemotherapeutic agents by upregulating drug transporters, which efflux the drugs, and by activating proliferation and survival signaling pathways. Previously, we found that c-Abl and Arg non-receptor tyrosine kinases are activated in breast cancer, melanoma, and glioblastoma cells, and promote cancer progression. In this report, we demonstrate that the c-Abl/Arg inhibitor, …

Rv Dysfunction By Mri Is Associated With Elevated Transpulmonary Gradient And Poor Prognosis In Patients With Sickle Cell Associated Pulmonary Hypertension, Kim-Lien L. Nguyen, Shoaib Alam, Xin Tian, Steve W. Leung, Catherine Seamon, Caterina P. Minniti, James G. Taylor, Vandana Sachdev, Andrew E. Arai, Gregory J. Kato

Internal Medicine Presentations

Patients with sickle cell disease (SCD) and pulmonary hypertension (PH) have increased mortality. SCD-PH is often complicated by high cardiac output (CO) related to anemia. The transpulmonary gradient (TPG) reflects a pressure differential across the pulmonary vascular bed without the confounding effect of CO (PVR=TPG/CO). Based on the cardiac transplant literature, a TPG ≥ 12 mmHg indicates significant pulmonary arterial hypertension (PAH). With PH, there is often morphologic adaptation by the right ventricle (RV). In idiopathic PAH, RV dilation and decreased function have been correlated with poor prognosis. We hypothesize that patients with SCD and a TPG ≥ 12 mmHg …

Horses were domesticated from the Eurasian steppes 5,000-6,000 years ago. Since then, the use of horses for transportation, warfare, and agriculture, as well as selection for desired traits and fitness, has resulted in diverse populations distributed across the world, many of which have become or are in the process of becoming formally organized into closed, breeding populations (breeds). This report describes the use of a genome-wide set of autosomal SNPs and 814 horses from 36 breeds to provide the first detailed description of equine breed diversity. F(ST) calculations, parsimony, and distance analysis demonstrated relationships among the breeds that largely reflect …

Commentary: Models Of Dissemination And Implementation In Public Health, Glen Mays

Frontiers in Public Health Services and Systems Research

As public health researchers and public health practitioners, we need to become much more skilled in applying dissemination and implementation models within our research designs and within our delivery systems if we want the accumulating scientific knowledge to result in improvements in population health. Many of our standard public health tools can be affective in facilitating D&I – regulation, education, measurement and reporting, peer pressure, social media, and economic incentives – but context really matters. The basic message behind this article is clear: choose your D&I model carefully and strategically to maximize the likelihood of success.

Models In Dissemination And Implementation Research: Useful Tools In Public Health Services And Systems Research, Rachel G. Tabak, Elaine C. Khoong, David Chambers, Ross C. Brownson

Frontiers in Public Health Services and Systems Research

Dissemination and implementation (D&I) science seeks to understand how to systematically facilitate utilization of evidence. Theories and frameworks (hereafter called models) augment D&I research by enhancing efforts to spread evidence-based interventions (EBIs). D&I models are relevant for public health services and systems research, which also explores the uses of evidence. This report: 1) develops an inventory of models; 2) synthesizes this information; and 3) provides guidance on how to select a model. The research team used snowball sampling to collect models. This article uses three author-defined variables: construct flexibility, focus on dissemination and/or implementation activities, and socio-ecological framework level to …

A Patient-Centered Approach For Evaluating Public Health Roles Within Systems Of Care For Children With Special Healthcare Needs, Danielle M. Varda, Ayelet Talmi

Frontiers in Public Health Services and Systems Research

Despite the apparent success that local and state health departments have had integrating a public health approach to provide programs and services for families with children who have complex health needs, there continues to be mixed results in terms of satisfaction and degree of support from this system. Current evaluations collect performance data from system stakeholders, rarely including the patient perspective. Examining the system holistically using Social Network Analysis, to include both the stakeholder and patient perspectives of how well the system is functioning affords greater understanding of how a public health approach to systems of care leads to more …

Frontiers in Public Health Services and Systems Research

In Hospital Tax-Exempt Policy: A Comparison of Schedule H and State Community Benefit Reporting Systems, Rosenbaum et aldescribe the numerous variations between current state law in 24 states and federal requirements regarding nonprofit hospitals’ community benefit activities. The potential for nonprofit hospitals to help shape community health is great, and how states choose to address requirements regarding community benefit, and potentially reinforce the new federal requirements to incentivize hospital participation in addressing root causes of poor health, should be of significant interest to the public, policy makers and public and population health experts, given the large percentage of …

Hospital Tax-Exempt Policy: A Comparison Of Schedule H And State Community Benefit Reporting Systems, Sara Rosenbaum, Maureen Byrnes, Amber M. Rieke

Frontiers in Public Health Services and Systems Research

The Patient Protection and Affordable Care Act (ACA) revises federal tax exemption standards for nonprofit hospitals by clarifying and augmenting their community benefit obligations. The ACA amendments followed the 2009 launch of Schedule H – the form on which hospital community benefit, financial, and institutional activities are reported and which must be appended to each facility’s annual Form 990 nonprofit institution information return. Schedule H effectively creates a nationwide, standardized, facility-specific, transparent, and fully publicly accessible reporting system covering the nation’s more than 2,900 nonprofit hospitals. Schedule H delineates financial assistance and bad debt, and requires identification of community health …

Carrots, Sticks And False Carrots: How High Should Weight Control Wellness Incentives Be? Findings From A Population-Level Experiment, Harald Schmidt

Frontiers in Public Health Services and Systems Research

Employers are increasingly using wellness incentives, including penalties for unhealthy behavior. Survey data suggests that people are willing to accept the principle of penalizing those perceived to take health risks, but the equally relevant question of the magnitude of acceptable penalties is unclear.

While the principle of penalizing overweight and obese people has some support, findings from a population-level experiment (n=1,000) suggest that the acceptable size of penalties is comparatively small, around $50: more than 10-fold below levels favored by advocates. Reward-based incentives are favored over penalty-based ones by a factor of 4. Of two different ways of framing penalty …

Learning By Doing For Public Health Improvement, Glen P. Mays

Frontiers in Public Health Services and Systems Research

All too often, the knowledge gained through learning-by-doing in public health fails to be fully harvested and disseminated because of missed opportunities to carefully study the experiences and innovations occurring in practice. The field of public health services and systems research (PHSSR) has emerged to capitalize on these opportunities before they are missed.

Activation Of Thromboxane A2 Receptor (Tp) Increases The Expression Of Monocyte Chemoattractant Protein -1 (Mcp-1)/Chemokine (C-C Motif) Ligand 2 (Ccl2) And Recruits Macrophages To Promote Invasion Of Lung Cancer Cells, Xiuling Li, Hsin-Hsiung Tai

Pharmaceutical Sciences Faculty Publications

Thromboxane synthase (TXAS) and thromboxane A₂ receptor (TP), two critical components for thromboxane A₂ (TXA₂) signaling, have been suggested to be involved in cancer invasion and metastasis. However, the mechanisms by which TXA₂ promotes these processes are still unclear. Here we show that TXA₂ mimetic, I-BOP, induced monocyte chemoattractant protein -1(MCP-1)/chemokine (C-C motif) ligand 2 (CCL2) expression at both mRNA and protein levels in human lung adenocarcinoma A549 cells stably over-expressing TP receptor α isoform (A549-TPα). The induction of MCP-1 was also found in other lung cancer cells H157 and H460 that express relatively …
