Cardiopulmonary Predicators Of Dysfunctional Ventilator Weaning Response After Coronary Artery Bypass Graft, Annapoorna Mary
Cardiopulmonary Predicators Of Dysfunctional Ventilator Weaning Response After Coronary Artery Bypass Graft, Annapoorna Mary
Theses and Dissertations (ETD)
Although the majority of coronary artery bypass graft (CABG) surgery patients are extubated within 6 to 8 hours following surgery, 20% to 40% of patients remain intubated 12 hours after surgery due to dysfunctional ventilator weaning response (DVWR). DVWR associated with increased morbidity and mortality (30% to 43%) following CABG surgery. Finding significant antecedence to predict DVWR could help to identify and prevent the complications from DVWR after CABG surgery. Literature review revealed that there is an association between cardiopulmonary indicators (CPI) and DVWR after CABG surgery. Cardiopulmonary indicators are the selected hemodynamic parameters that have an association with DVWR. …

Transcriptional Control Of Vascular Smooth Muscle Cell Proliferation By Peroxisome Proliferator-Activated Receptor-Γ: Therapeutic Implications For Cardiovascular Diseases, Florence Gizard, Dennis Bruemmer
Internal Medicine Faculty Publications
Proliferation of vascular smooth muscle cells (SMCs) is a critical process for the development of atherosclerosis and complications of procedures used to treat atherosclerotic diseases, including postangioplasty restenosis, vein graft failure, and transplant vasculopathy. Peroxisome proliferator-activated receptor (PPAR) gamma is a member of the nuclear hormone receptor superfamily and the molecular target for the thiazolidinediones (TZD), used clinically to treat insulin resistance in patients with type 2 diabetes. In addition to their efficacy to improve insulin sensitivity, TZD exert a broad spectrum of pleiotropic beneficial effects on vascular gene expression programs. In SMCs, PPARgamma is prominently upregulated during neointima formation …
Uniform Particles Of Pure And Silica Coated Cholesterol, Vuk Uskoković, Egon Matijević
Uniform Particles Of Pure And Silica Coated Cholesterol, Vuk Uskoković, Egon Matijević
Pharmacy Faculty Articles and Research
Uniform crystalline colloidal cholesterol particles of narrow size distribution were obtained by precipitation. The method consisted of adding a miscible non-solvent (water) into cholesterol solutions of different alcohols and acetone, without any additives. The properties of the resulting particles depended in a sensitive way on the concentration of all reactants, temperature, pH, ionic strength, and aging time. The major observed effects were due to the solubility of cholesterol, which was strongly affected by the solvent mixture and temperature. Precipitation in 1-propanol/water system yielded stable dispersions of well-defined particles, which were used to evaluate the effects of different experimental parameters on …

Publications and Research
Background
Sex differences in lipids and body shape, but not diabetes, increase at puberty. Hong Kong Chinese are mainly first or second generation migrants from China, who have shared an economically developed environment for years, but grew up in very different environments in Hong Kong or contemporaneously undeveloped Guangdong, China. We assessed if environment during growth had sex-specific associations with lipids and body shape, but not diabetes.
Methodology and Principal Findings
We used multivariable regression in a population-based cross-sectional study, undertaken from 1994 to 1996, of 2537 Hong Kong Chinese residents aged 25 to 74 years with clinical measurements of …

Repeatability Of Serial Carotid Intima Media Thickness Scanning On Individual Subjects, Judi Nightingale
Repeatability Of Serial Carotid Intima Media Thickness Scanning On Individual Subjects, Judi Nightingale
Loma Linda University Electronic Theses, Dissertations & Projects
Background. Heart disease affects millions of Americans each year. In order to improve primary prevention, early risk identification is essential. B-mode ultrasound of the common carotid artery (CCA) intima-media thickness (IMT) assesses risk of a coronary event early in the process of plaque development. Because IMT changes are so small over time, in order to determine clinically significant versus clinically insignificant changes in IMT over a 12 month time period, a protocol is needed which can detect the least significant difference (LSD) of at least 0.030 mm.
Purpose. The purpose of this study was to develop and test a well-defined …
The Association Between Lifestyle Factors And Inflammatory Markers, Kerry Ann Stonebrook
The Association Between Lifestyle Factors And Inflammatory Markers, Kerry Ann Stonebrook
Loma Linda University Electronic Theses, Dissertations & Projects
Background: Cardiovascular disease (CVD) is the leading cause of death for both men and women in the United States. While smoking, high blood pressure, and elevated cholesterol levels are established risk factors for CVD, inflammation is being evaluated as a potential independent risk factor. A key cytokine regulator of the inflammatory response, interleukin-1 (IL-1), has emerged as playing a particularly important role at the genetic level in determining the degree to which the inflammation pathway is turned on. How an individual’s genetic make-up affects inflammation, CVD risk, and response to lifestyle intervention is an area of research that is in …
New Developments In Understanding Cardiovascular Disease And The Implications For Social Work, Jill Littrell
New Developments In Understanding Cardiovascular Disease And The Implications For Social Work, Jill Littrell

Cardiovascular disease is now viewed as an inflammatory disease. An index of chronic inflammation (viz., C-Reactive Protein) is as good a predictor of heart attacks as are fats in blood. The data suggest that stressful events are so closely associated with chronic inflammatory states, that the body’s stress response can be viewed as an inflammatory state. This paper summarizes and explains the link between stress and cardiovascular disease. Negative health outcomes, particularly for cardiovascular diseases, are higher among those of lower socio-economic status. Differential stress among socio-economic tiers is considered as an explanation for the disparities. The literature linking cardiovascular …

Stroke mortality rates have a discrepant distribution according to socioeconomic variables as social exclusion in Brazil. Recently, data from race has been available from the official health statistics considering five categories: White, Mixed, Black, Asian and Native. We addressed in the city of São Paulo, Brazil, an analysis of cerebrovascular mortality according to race (excluding Asian and Native due to small number of events) and gender during 1999-2001 for people aged 30 to 79 years-old. For all cerebrovascular diseases, age-adjusted mortality rates (x 100,000) for men were higher for Black (150.2), intermediate for Mixed (124.2) and lower for White (104.5) …

There are few effective agents that safely remove excess iron from iron-overloaded individuals. Our goal was to evaluate the iron-removing effectiveness of acetaminophen given ip or orally in the gerbil iron-overload model. Male gerbils were divided into 5 groups: saline controls, iron-overloaded controls, iron-overloaded treated with ip acetaminophen, iron-overloaded treated with oral acetaminophen, and iron-overloaded treated with ipdeferoxamine. Iron dextran was injected iptwice/wk for 8 wk. Acetaminophen and deferoxamine treatments were given on Mondays, Wednesdays, and Fridays during the same 8 wk and continued for 4 wk after completion of iron-overloading. Echocardiograms were performed after completion of the iron-overloading and …
The Effect Of Walnuts Compared To Fatty Fish On Plasma And Erythrocyte Fatty Acid Composition, Lymphocyte Subsets And Inflammatory Mediators, Yu-Lan Ching
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study was to compare the effects of walnuts vs. fatty fish on circulating inflammatory markers, on lymphocyte subsets, on plasma concentrations of eicosanoids precursor polyunsaturated fatty acid and on erythrocyte membrane fatty acid composition. Under controlled metabolic feeding conditions and randomized crossover (3x3 Latin-square) design, 27 subjects alternately consumed a control diet, a walnut diet (1.5 oz (42.5g) /day of walnuts, 6 times/week) or a fish diet (8 oz (226g) /week of salmon) for 4 weeks each. Consumption of the walnut diet (ALA 5.43 g/day) compared to the fish diet (EPA 170 mg/day and DHA 590 …

A Computational Model For Analysis Of Uncoupled No Synthase On Nitric Oxide And Superoxide Interaction In Microcirculation, William Richardson, Mahendra Kavdia
A Computational Model For Analysis Of Uncoupled No Synthase On Nitric Oxide And Superoxide Interaction In Microcirculation, William Richardson, Mahendra Kavdia
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Nitric oxide (NO) produced by endothelial cells is a key component for blood-vessel dilation. Dilation is achieved through smooth muscle relaxation as a response to NO transport. Inhibition of this process occurs through the inactivation of NO by reactive oxygen species, especially superoxide (O2 -). NO and superoxide react quickly, forming peroxynitrite (ONOO-). Both superoxide and peroxynitrite apply oxidative stress on vascular tissue. Experimental studies investigating NO interactions are difficult since these reactions occur rapidly and over small distances. This study presents a computational model to describe the interactions of NO, superoxide, and peroxynitrite across an arteriole/venule pair. Based on …

Sunshine And Suicide At The Tropic Of Capricorn, São Paulo, Brazil, 1996–2004, Paulo A. Lotufo
Paulo A Lotufo
Several studies have confi rmed seasonal variation in suicide rates according to hours of sunshine. The suicide pattern was assessed in São Paulo, southeastern Brazil, at the tropic of Capricorn from 1996 to 2004. Poisson regression was employed to estimate parameters of seasonality, as well as to verify associations for each day between daylight duration and suicide. During the nine-year study period, there were 3,984 suicides (76.9% in men; median age=38.7 years old). Seasonal averages of suicides were similar, as were monthly averages. Poisson regression did not reveal any association between suicide rates and hours of sunshine (p=0.45) for both …
