Haematopoietic Stem Cells In Spleen Have Distinct Differentiative Potential For Antigen Presenting Cells., Jonathan Tan, Helen O'Neill

Jonathan Tan

Dendritic cells (DC) are known to develop from macrophage dendritic progenitors (MDP) in bone marrow (BM), which give rise to conventional (c)DC and monocytes, both dominant antigen presenting cell (APC) subsets in spleen. This laboratory has however defined a distinct dendritic-like cell subset in spleen (L-DC), which can also be derived in long-term cultures of spleen. In line with the restricted in vitro development of only L-DC in these stromal cultures, we questioned whether self-renewing HSC or progenitors exist in spleen with restricted differentiative capacity for only L-DC. Neonatal spleen and BM were compared for their ability to reconstitute mice …

Age And Sex Differences And 20-Year Trends (1986 To 2005) In Prehospital Delay In Patients Hospitalized With Acute Myocardial Infarction, Hoa Nguyen, Joel Gore, Jane Saczynski, Jorge Yarzebski, George Reed, Frederick Spencer, Robert Goldberg

Jorge L. Yarzebski

Background: The prompt administration of coronary reperfusion therapy for patients with an evolving acute myocardial infarction (AMI) is crucial in reducing mortality and the risk of serious clinical complications in these patients. However, long-term trends in extent of prehospital delay and factors affecting patient's care-seeking behavior remain relatively unexplored, especially in men and women of different ages. The objectives of this study were to examine the overall magnitude and 20-year trends (1986 to 2005) in duration of prehospital delay in middle-aged and elderly men and women hospitalized with AMI.

Methods and Results: The study sample consisted of 5967 residents of …

Developing Constructs For Psychopathology Research: Research Domain Criteria, Charles A. Sanislow, Daniel S. Pine, Kevin J. Quinn, Michael J. Kozak, Marjorie A. Garvey, Robert K. Heinssen, Philip Sung-En Wang, Bruce N. Cuthbert

Charles A. Sanislow, Ph.D.

There exists a divide between findings from integrative neuroscience and clinical research focused on mechanisms of psychopathology. Specifically, a clear correspondence does not emerge between clusters of complex clinical symptoms and dysregulated neurobiological systems, with many apparent redundancies. For instance, many mental disorders involve multiple disruptions in putative mechanistic factors (e.g., excessive fear, deficient impulse control), and different disrupted mechanisms appear to play major roles in many disorders. The Research Domain Criteria (RDoC) framework is a heuristic to facilitate the incorporation of behavioral neuroscience in the study of psychopathology. Such integration might be achieved by shifting the central research focus …

Edward Yu

OBJECTIVES: The present study investigated factors affecting outcome at relapse after previous surgery and adjuvant chemoradiation (crt) in high-risk esophageal cancer patients. PATIENTS AND METHODS: From 1989 to 1999, we followed high-risk resected esophageal cancer patients who had completed postoperative crt therapy. Patients who relapsed with a disease-free interval of less than 3 months were treated with palliative crt when appropriate. Patients with a disease-free interval of 3 months or more were treated with best supportive care. Post-recurrence survival was estimated using the Kaplan-Meier technique, and statistical comparisons were made using log-rank chi-square tests and Cox regression. RESULTS: Of the …

Doxorubicin Loaded Polymeric Nanoparticulate Delivery System To Overcome Drug Resistance In Osteosarcoma, Michiro Susa, Arun K. Iyer, Keinosuke Ryu, Francis John Hornicek, Henry J. Mankin, Mansoor M. Amiji, Zhenfeng Duan

Mansoor M. Amiji

Background: Drug resistance is a primary hindrance for the efficiency of chemotherapy against osteosarcoma. Although chemotherapy has improved the prognosis of osteosarcoma patients dramatically after introduction of neo-adjuvant therapy in the early 1980's, the outcome has since reached plateau at approximately 70% for 5 year survival. The remaining 30% of the patients eventually develop resistance to multiple types of chemotherapy. In order to overcome both the dose-limiting side effects of conventional chemotherapeutic agents and the therapeutic failure incurred from multidrug resistant (MDR) tumor cells, we explored the possibility of loading doxorubicin onto biocompatible, lipid-modified dextran-based polymeric nanoparticles and evaluated the …

Inhibition Of Abcb1 (Mdr1) Expression By An Sirna Nanoparticulate Delivery System To Overcome Drug Resistance In Osteosarcoma, Michiro Susa, Arun K. Iyer, Keinosuke Ryu, Edwin Choi, Francis John Hornicek, Henry J. Mankin, Lara Milane, Mansoor M. Amiji, Zhenfeng Duan

Mansoor M. Amiji

Background: The use of neo-adjuvant chemotherapy in treating osteosarcoma has improved patients’ average 5 year survival rate from 20% to 70% in the past 30 years. However, for patients who progress after chemotherapy, its effectiveness diminishes due to the emergence of multi-drug resistance (MDR) after prolonged therapy. Methodology/Principal Findings: In order to overcome both the dose-limiting side effects of conventional chemotherapeutic agents and the therapeutic failure resulting from MDR, we designed and evaluated a novel drug delivery system for MDR1 siRNA delivery. Novel biocompatible, lipid-modified dextran-based polymeric nanoparticles were used as the platform for MDR1 siRNA delivery; and the efficacy …

Update On The Management Of Chronic Obstructive Pulmonary Disease, Andrea K. Maas, David M. Mannino

David M. Mannino

Chronic obstructive pulmonary disease is a highly prevalent, underdiagnosed, and undertreated chronic lung disease. Early and appropriate treatment may help modify the course of the disease with respect to exacerbation timing and frequency, quality of life, and mortality. Steady progress continues to be made in understanding the disease pathogenesis and treatment modalities, and there is some evidence that outcomes are improving.

Clinical Diagnostic Criteria For Isolating Patients Admitted To Hospital With Suspected Pandemic Influenza, John Gerrard, Gerben Keijzers, Ping Zhang, Caleb Vossen, Deborough Macbeth

Gerben Keijzers

Extract: Australian hospitals have now experienced the first wave of pandemic H1N1 influenza during a southern hemisphere winter. Patients admitted to Australian hospitals with suspected pandemic influenza during this period were identified by use of approved national clinical diagnostic criteria. However, the imprecise nature of clinical diagnosis limited the ability of hospitals to isolate infectious patients effectively before the laboratory confirmation of infection (which typically takes a minimum of 48 h).

Psychometric Characteristics And Clinical Correlates Of Neo-Pi-R Fearless Dominance And Impulsive Antisociality In The Collaborative Longitudinal Personality Disorders Study, Edward A. Witt, Christopher J. Hopwood, Leslie C. Morey, John C. Markowitz, Thomas H. Mcglashan, Carlos M. Grilo, Charles A. Sanislow, M. Tracie Shea, Andrew E. Skodol, John G. Gunderson, M. Brent Donnellan

Charles A. Sanislow, Ph.D.

This study evaluates the validity of derived measures of the psychopathic personality traits of Fearless Dominance and Impulsive Antisociality from the NEO Personality Inventory-Revised (NEO-PI-R; Costa & McCrae, 1992) using data from the Collaborative Longitudinal Personality Disorders Study (baseline N = 733). These 3 issues were examined: (a) the stability of the measures over a 10-year interval, (b) their criterion-related validity, and (c) their incremental validity relative to an alternative NEO-PI-R profile-rating approach for assessing psychopathy. NEO-PI-R Fearless Dominance and Impulsive Antisociality scales were relatively stable across 10 years and demonstrated differential associations with measures of personality pathology and psychopathology …
