Human Amnion As A Novel Cell Delivery Vehicle For Chondrogenic Mesenchymal Stem Cells, Tunku Kamarul Zaman

Tunku Kamarul Zaman

This study investigates the feasibility of processed human amnion (HAM) as a substrate for chondrogenic differentiation of mesenchymal stem cells (MSCs). HAM preparations processed by air drying (AD) and freeze drying (FD) underwent histological examination and MSC seeding in chondrogenic medium for 15 days. Monolayer cultures were used as control for chondrogenic differentiation and HAMs without cell seeding were used as negative control. Qualitative observations were made using scanning electron microscopy analysis and quantitative analyses were based on the sulfated glycosaminoglycans (GAG) assays performed on day 1 and day 15. Histological examination of HAM substrates before seeding revealed a smooth …

Post-Operative Extended Volume External Beam Radiation Therapy Is Safe For High Risk Esophageal Cancer Patients, Edward Yu, Patricia Tai, Jawaid Younus, Richard Malthaner, Larry Stitt, Pauline Truong, George Rodrigues, Robert Ash, Rashid Dar, Anna Tomiak, Mark Vincent, Walter Kocha, Brian Dingle, Richard Inculet

Edward Yu

Post-operative radiation therapy (RT) (1) and post-operative chemoradiation (2) have been used for esophageal cancer patients deemed high risk for recurrence after esophagectomy. Defining opitmal RT target volume after esophagectomy is difficult due to significant changes in patient anatomy and function. Some radiationon cologists advocated the inclusion of the anastomotic site within the irradiation volume due to concerns for potential increased relapse risk, while others did not subscribe to this practice due to concerns for increased treatment related toxicity. We have previously reported patient outcome benefit using extended volume RT In management with high risk esophageal cancer patients underwent esopagectomy(3). …

Prevalence Of Copd Among Symptomatic Patients In A Primary Care Setting, Barbara Yawn, David M. Mannino, Thomas Littlejohn, Gary Ruoff, Amanda Emmett, Ibrahim Raphiou, Glenn Crater

David M. Mannino

Objective: Spirometry is recognized as the gold standard assessment for the diagnosis of COPD. However, spirometry continues to be underused, perpetuating the underdiagnosis of COPD. The aim of this study was to evaluate the prevalence of COPD in a primary care setting in patients with a smoking history and self-reported chronic bronchitis symptoms.

Research design and methods: This was a multi-center, cross-sectional study. The primary assessment was the percentage of patients with airway obstruction (post-bronchodilator FEV1/FVC ratio ≤ 0.70) compared to those without obstruction (post-bronchodilator FEV1/FVC ratio > 0.70).

Results: Airflow obstruction consistent with COPD was confirmed in 26% of patients …

The Stability Of Personality Traits In Individuals With Borderline Personality Disorder, Christopher J. Hopwood, Daniel A. Newman, M. Brent Donnellan, John C. Markowitz, Carlos M. Grilo, Charles A. Sanislow, Emily B. Ansell, M. Tracie Shea, Andrew E. Skodol, Thomas H. Mcglashan, John G. Gunderson, Mary C. Zanarini, Leslie C. Morey

Charles A. Sanislow, Ph.D.

Although stability and pervasive inflexibility are general criteria for Diagnostic and Statistical Manual of Mental Disorders, 4th edition (American Psychiatric Association, 1994) personality disorders (PDs), borderline PD (BPD) is characterized by instability in several domains, including interpersonal behavior, affect, and identity. The authors hypothesized that such inconsistencies notable in BPD may relate to instability at the level of the basic personality traits that are associated with this disorder. Five types of personality trait stability across 4 assessments over 6 years were compared for BPD patients (N = 130 at first interval) and patients with other PDs (N = 302). Structural …

Association Of Ambient Ozone Exposure With Airway Inflammation And Allergy In Adults With Asthma, Sumita B. Khatri, Fernando C. Holguin, P. Barry Ryan, David M. Mannino, Serpil C. Erzurum, W. Gerald Teague

David M. Mannino

Rationale

Previous studies have demonstrated associations of high ozone levels with increased epidemiologic as well as lung function measures of asthma activity.

Objectives

In an observational study during the summer months, we hypothesized that higher ambient ozone levels are associated with more frequent symptoms, higher airway and systemic inflammation, as well as worse lung function in asthmatics as compared with non-asthmatic individuals.

Methods

Thirty-eight asthmatics and thirteen healthy control subjects residing in metropolitan Atlanta were enrolled during peak ozone season. Medical histories, quality-of-life questionnaires, spirometry, serum immunoglobulin (IgE), peripheral eosinophil counts, and exhaled nitric oxide (NO) were obtained during study …

The Convergent And Discriminant Validity Of Five-Factor Traits: Current And Prospective Social, Work, And Recreational Dysfunction, Christopher J. Hopwood, Leslie C. Morey, Emily B. Ansell, Carlos M. Grilo, Charles A. Sanislow, Thomas H. Mcglashan, John C. Markowitz, John G. Gunderson, Shirley Yen, M. Tracie Shea, Andrew E. Skodol

Charles A. Sanislow, Ph.D.

The convergent and discriminant validity of Five Factor Model (FFM) personality traits with concurrent and prospective social, work, and recreational dysfunction was assessed in a large, longitudinal clinical sample. Consistent with five factor theoretical expectations, neuroticism is broadly related to dysfunction across domains; extraversion is primarily related to social and recreational dysfunction; openness to recreational dysfunction; agreeableness to social dysfunction; and conscientiousness to work dysfunction. Findings support five factor theory and the clinical assessment of normative personality traits.

Cox proportional hazards regression analyses was used to examine NA and DIS, and facets of impulsivity (e.g. urgency, lack of perseverance, lack of premeditation and sensation seeking), as prospective predictors of suicide attempts.

RESULTS: NA, DIS and all facets of impulsivity except for …

Postulated Role Of Vasoactive Neuropeptide-Related Immunopathology Of The Blood Brain Barrier And Virchow-Robin Spaces In The Aetiology Of Neurological-Related Conditions, Donald R. Staines, Ekua W. Brenu, Sonya Marshall-Gradisnik

Sonya Marshall-Gradisnik

Vasoactive neuropeptides (VNs) such as pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal peptide (VIP) have critical roles as neurotransmitters, vasodilators including perfusion and hypoxia regulators, as well as immune and nociception modulators. They have key roles in blood vessels in the central nervous system (CNS) including maintaining functional integrity of the blood brain barrier (BBB) and blood spinal barrier (BSB). VNs are potent activators of adenylate cyclase and thus also have a key role in cyclic AMP production affecting regulatory T cell and other immune functions. Virchow-Robin spaces (VRSs) are perivascular compartments surrounding small vessels within the CNS and …

Modeling Brain Tumors Using Avian Retroviral Gene Transfer, Tod D. Holland, Eric C. Holland

Tod D Holland

RCAS/tv-a is a system for post-natal cell type specific gene transfer. It is used for the modeling of gliomas and medulloblastomas. This system provides a combination of lineage tracing from the cell origin with oncogenesis induced by mis-expression of specific genes. The genes that are most potent at inducing tumors are those that encode components of signal transduction and undifferentiated cells are most capable of serving as the cell of origin. The system effectively generates tumors with the histologic characteristics of human disease. Mice bearing RVAS/tv-a induced brain tumors are currently being used for preclinical trials to understand the biology …

F-2-Isoprostanes As Novel Biomarkers For Type 2 Diabetes: A Review, Ikram Shah Ismail

Ikram Shah Ismail

Oxidative stress (OS) has been implicated as one of the major underlying mechanisms behind many acute and chronic diseases. However, the measurement of free radicals or their end products is complicated. Isoprostanes, derived from the non-enzymatic peroxidation of arachidonic acid are now considered to be reliable biomarkers of oxidant stress in the human body. Isoprostanes are involved in many of the human diseases such as type 2 diabetes. In type 2 diabetes elevated levels of F-2-Isoprostanes (F-2-IsoPs) have been observed. The measurement of bioactive F-2-IsoPs levels offers a unique noninvasive analytical tool to study the role of free radicals in …

Symptoms Of Diminished Autonomy Over Cigarettes With Non-Daily Use, Judith A. Savageau, Paul D. Mowery, Joseph R. Difranza

Judith A. Savageau

Data from a nationally representative sample of smokers (ages 12-22 years, n=2,091) was examined to investigate the prevalence of symptoms of diminished autonomy over cigarettes. Six symptoms were assessed: failed cessation, smoking despite a desire to quit, and a need or urge to smoke, irritability, restlessness, or disrupted concentration attributed to nicotine withdrawal. One or more of the six symptoms were present in 18.9% of subjects who smoked less often than once per week. Among subjects who had not smoked 20 cigarettes in their lifetime, 12.6% had symptoms of nicotine withdrawal, and 25% had made an unsuccessful quit attempt.
