Successfully Climbing The "Stairs": Surmounting Failed Translation Of Experimental Ischemic Stroke Treatments, Michael Kahle, Gregory J. Bix

Sanders-Brown Center on Aging Faculty Publications

The Stroke Therapy Academic Industry Roundtable (STAIR) provided initial (in 1999) and updated (in 2009) recommendations with the goal of improving preclinical stroke therapy assessment and to increase the translational potential of experimental stroke treatments. It is important for preclinical stroke researchers to frequently consider and revisit these concepts, especially since promising experimental stroke treatments continue to fail in human clinical trials. Therefore, this paper will focus on considerations for several key aspects of preclinical stroke studies including the selection and execution of the animal stroke model, drug/experimental treatment administration, and outcome measures to improve experimental validity and translation potential. …

Parallel Ngo Networks For Hiv Control: Risks And Opportunities For Ngo Contracting., Shehla Zaidi, Xaher Gul, Noureen Aleem Nishtar

Community Health Sciences

Policy measures for preventive and promotive services are increasingly reliant on contracting of NGOs. Contracting is a neo-liberal response relying on open market competition for service delivery tenders. In contracting of health services a common assumption is a monolithic NGO market. A case study of HIV control in Pakistan shows that in reality the NGO market comprises of parallel NGO networks having widely different service packages, approaches and agendas. These parallel networks had evolved over time due to vertical policy agendas. Contracting of NGOs for provision of HIV services was faced with uneven capacities and turf rivalries across both NGO …

Genomic Loss Of Tumor Suppressor Mirna-204 Promotes Cancer Cell Migration And Invasion By Activating Akt/Mtor/Rac1 Signaling And Actin Reorganization, Saadi J. Imam, Jason R. Plyler, Hima Bansal, Suresh Prajapati, Sanjay Bansal, Jennifer Rebeles, Jeffrey S. Dome, +12 Additional Authors

Pediatrics Faculty Publications

Increasing evidence suggests that chromosomal regions containing microRNAs are functionally important in cancers. Here, we show that genomic loci encoding miR-204 are frequently lost in multiple cancers, including ovarian cancers, pediatric renal tumors, and breast cancers. MiR-204 shows drastically reduced expression in several cancers and acts as a potent tumor suppressor, inhibiting tumor metastasis in vivo when systemically delivered. We demonstrated that miR-204 exerts its function by targeting genes involved in tumorigenesis including brain-derived neurotrophic factor (BDNF), a neurotrophin family member which is known to promote tumor angiogenesis and invasiveness. Analysis of primary tumors shows that increased expression …

Stress And Strain Adaptation In Load-Dependent Remodeling Of The Embryonic Left Ventricle, Christine Buffinton

Faculty Journal Articles

Altered pressure in the developing left ventricle (LV) results in altered morphology and tissue material properties. Mechanical stress and strain may play a role in the regulating process. This study showed that confocal microscopy, three-dimensional reconstruction, and finite element analysis can provide a detailed model of stress and strain in the trabeculated embryonic heart. The method was used to test the hypothesis that end-diastolic strains are normalized after altered loading of the LV during the stages of trabecular compaction and chamber formation. Stage-29 chick LVs subjected to pressure overload and underload at stage 21 were reconstructed with full trabecular morphology …

Current Opinion On Nanotoxicology, Ali Pourmand, Mohammad Abdollahi

Emergency Medicine Faculty Publications

Nanotechnology is one of the premiere technologies available today, having expanded both as field of scientific study and in the public consciousness. Despite this growth, the drawbacks, limitations and potential safety hazards associated with the incorporation of nanotechnology into existing industries are still being learned. The noticeable point is that there is no enough data available yet to analyze global use of nanotechnology from a meta-perspective. Three challenges can be defined in light of nanotoxicology. One, materials that might prove to be significantly toxic must be identified. Two, a system for the categorization of NP materials must be codified and …

Barnstable Brown Diabetes Center Faculty Publications

Exercise can increase skeletal muscle sensitivity to insulin, improve insulin resistance and regulate glucose homeostasis in rat models of type 2 diabetes. However, the potential mechanism remains poorly understood. In this study, we established a male Sprague-Dawley rat model of type 2 diabetes, with insulin resistance and β cell dysfunction, which was induced by a high-fat diet and low-dose streptozotocin to replicate the pathogenesis and metabolic characteristics of type 2 diabetes in humans. We also investigated the possible mechanism by which chronic and acute exercise improves metabolism, and the phosphorylation and expression of components of AMP-activated protein kinase (AMPK) and …

Prenatal Genetic Diagnosis Using Transcervically Derived And Immunomagnetically Isolated Trophoblast Cells, Swati Bajpayee

Honors College Theses

Trophoblast cells migrate from the placenta into the endocervical canal early in the first trimester and can be collected non-invasively by transcervical sampling (TCS), potentially providing fetal DNA for prenatal genetic diagnosis. Experiments were conducted to separate fetal cells from maternal cells within the TCS specimens and use the fetal cells to perform genetic analysis. Trophoblast cells were efficiently isolated from TCS specimens during weeks 5-18 of gestation using HLA-G antibody coupled to magnetic nanoparticles. Immunofluorescence microscopy revealed that 99% of isolated cells expressed the chorionic gonadotropin β subunit (β-CG), while the non-bound cell fraction expressed none. Immunomagnetically isolated cells …

Zaidi, Sajid Bashir Soofi, Ali Turab, Didar Alam, Shahida Qureshi, Aisha Khizar Yousafzai, Syed Asad Ali, Imran Ahmed, Sajad Memon, Muneera Rasheed

Woman and Child Health

Background: Stunting results from decreased food intake, poor diet quality, and a high burden of early childhood infections, and contributes to significant morbidity and mortality worldwide. Although food insecurity is an important determinant of child nutrition, including stunting, development of universal measures has been challenging due to cumbersome nutritional questionnaires and concerns about lack of comparability across populations. We investigate the relationship between household food access, one component of food security, and indicators of nutritional status in early childhood across eight country sites.
Methods: We administered a socioeconomic survey to 800 households in research sites in eight countries, including a …

Alterations In Glutathione Levels And Apoptotic Regulators Are Associated With Acquisition Of Arsenic Trioxide Resistance In Multiple Myeloma, Shannon M. Matulis, Alejo A. Morales, Lucy Yehiayan, Kelvin P. Lee, Yong Cai, Lawrence H. Boise

Department of Chemistry and Biochemistry

Arsenic trioxide (ATO) has been tested in relapsed/refractory multiple myeloma with limited success. In order to better understand drug mechanism and resistance pathways in myeloma we generated an ATO-resistant cell line, 8226/S-ATOR05, with an IC50 that is 2–3-fold higher than control cell lines and significantly higher than clinically achievable concentrations. Interestingly we found two parallel pathways governing resistance to ATO in 8226/S-ATOR05, and the relevance of these pathways appears to be linked to the concentration of ATO used. We found changes in the expression of Bcl-2 family proteins Bfl-1 and Noxa as well as an increase in cellular glutathione (GSH) …

Rapid Synaptic Vesicle Endocytosis In Cone Photoreceptors Of Salamander Retina., Matthew J. Van Hook, Wallace B. Thoreson

Journal Articles: Ophthalmology

Following synaptic vesicle exocytosis, neurons retrieve the fused membrane by a process of endocytosis to provide a supply of vesicles for subsequent release and maintain the presynaptic active zone. Rod and cone photoreceptors use a specialized structure called the synaptic ribbon that enables them to sustain high rates of neurotransmitter release. They must also employ mechanisms of synaptic vesicle endocytosis capable of keeping up with release. While much is known about endocytosis at another retinal ribbon synapse, that of the goldfish Mb1 bipolar cell, less is known about endocytosis in photoreceptors. We used capacitance recording techniques to measure vesicle membrane …

Post-Transfusion Purpura In An African-American Man Due To Human Platelet Antigen-5b Alloantibody: A Case Report, Filipa Lynce, Fang Yin, Kirsten Alcorn, Vera Malkovska

Pediatrics Faculty Publications

Introduction

Post-transfusion purpura is a rare immunohematological disorder characterized by severe thrombocytopenia following transfusion of blood components and induced by an alloantibody against a donor platelet antigen. It occurs primarily in women sensitized by pregnancy and is most commonly caused by anti-human platelet antigen-1a antibodies. Here, we describe what we believe to be the first documented case of an African-American man who developed post-transfusion purpura due to an anti-human platelet antigen-5b alloantibody after receiving multiple blood products.

Case presentation

A 68-year-old African-American man initially admitted with atrial flutter was started on anticoagulation treatment, which was complicated by severe hematemesis. On …
