Sevoflurane Enhances Ethanol-Induced Cardiac Preconditioning Through Modulation Of Protein Kinase C, Mitochondrial Katp Channels, And Nitric Oxide Synthase, In Guinea Pig Hearts., Kazuhiro Kaneda, Masami Miyamae, Shingo Sugioka, Chika Okusa, Yoshitaka Inamura, Naochika Domae, Junichiro Kotani, Vincent M. Figueredo

Division of Cardiology Faculty Papers

BACKGROUND: Volatile anesthetics and regular ethanol consumption induce cardioprotection mimicking ischemic preconditioning. We investigated whether sevoflurane enhances ethanol preconditioning and whether inhibition of protein kinase C (PKC) and mitochondrial K(ATP) channels attenuated this enhanced cardioprotection. The effects of regular ethanol consumption on expression of inducible (iNOS) and endothelial (eNOS) nitric oxide synthase were determined. METHODS: Isolated perfused guinea pig hearts underwent 30-min global ischemia and 120-min reperfusion (Control: CTL). The ethanol group (EtOH) received 2.5% ethanol in their drinking water for 6 wk. Anesthetic preconditioning was elicited by 10-min exposure to sevoflurane (1 minimum alveolar anesthetic concentration; 2%) in ethanol …

Sensitization Of Ovarian Cancer Cells To Cisplatin By Genistein: The Role Of Nf-Kappab, Leigh A. Solomon, Shadan Ali, Sanjeev Banerjee, Adnan R. Munkarah, Robert T. Morris, Fazlul H. Sarkar

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Platinum-resistance (PR) continues to be a major problem in the management of epithelial ovarian cancer (EOC). Response to various chemotherapeutic agents is poor in patients deemed PR. Genistein, a soy isoflavone has been shown to enhance the effect of chemotherapy in prostate and pancreatic cancer cells in vitro and in vivo by reversing chemo-resistance phenotype. The goal of this study was to investigate the effects of combination therapy with genistein and cisplatin as well as other cytotoxic conventional chemotherapeutic agents in platinum-sensitive (PS) and resistant EOC cells.

Methods

The PS human ovarian cancer cell line A2780 and its …

A Stable Explant Culture Of Her2/Neu Invasive Carcinoma Supported By Alpha-Smooth Muscle Actin Expressing Stromal Cells To Evaluate Therapeutic Agents, Marie P. Piechocki

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

To gain a better understanding of the effects of therapeutic agents on the tumor microenvironment in invasive cancers, we developed a co-culture model from an invasive lobular carcinoma. Tumor cells expressing HER2/neu organize in nests surrounded by alpha-Smooth Muscle Actin (α-SMA) expressing tumor stroma to resemble the morphology of an invading tumor. This co-culture, Mammary Adenocarcinoma Model (MAM-1) maintains a 1:1 ratio of HER2/neu positive tumor cells to α-SMA-reactive stromal cells and renews this configuration for over 20 passages in vitro.

Methods

We characterized the cellular elements of the MAM-1 model by microarray analysis, and immunocytochemistry. We developed …

Functional Analysis Of Human Beta Defensin-1: Novel Insight Into Its Role In Prostate Cancer, Rebecca S. Bullard

MUSC Theses and Dissertations

Prostate cancer is the second leading cause of cancer-related deaths in men in the United States. The molecular pathogenesis of this disease includes genetic alterations, infection, and exposure to inflammatory or dietary oxidants. Recently, research has focused on the role of host defense peptides in tumor immunity. Defensins, a highly conserved multigene family of proteins that possess antimicrobial and antiviral properties, play an essential role in innate and adaptive immunity. These peptides are categorized into alpha- and beta-defensins based upon the spacing and connection between the six conserved cysteine residues of the mature peptide. Human Beta Defensin-1 (hBD-1), an important …

The Impact Of Traumatic Stress And Alcohol Exposure On Youth: Implications For Lawyers, Judges, And Courts, Frank E. Vandervort

Articles

Since its inception in the late nineteenth century, the juvenile court has been concerned with the legal problems of children and their families. From the court’s earliest days, it has sought to address child abuse and neglect and juvenile delinquency as social problems that result from familial and community breakdown. Over the decades, researchers from various disciplines have provided varying explanations of how and why family systems break down, why some parents fail to nurture their children, why some physically or sexually abuse their children, and why some children become delinquent.

Obesity, Hypertension, And Mental Health Evaluation In Adolescents: A Comprehensive Approach, Stefan G. Kiessling, Kimberly K. Mcclanahan, Hatim A. Omar

Pediatrics Faculty Publications

The global epidemic of childhood and adolescent obesity in developing and developed countries has become a major public health concern. Given the relation between obesity and hypertension as documented in several landmark studies, it is no surprise that as the prevalence of obesity has increased in the pediatric population, the rates of hypertension have also increased substantially. Hypertension is one of the most important risk factors for cardiovascular diseases and stroke; therefore, evaluation and initiation of appropriate treatment are extremely important in the pediatric population. Evaluation for secondary causes of hypertension, including renovascular, renoparenchymal, and endocrine disease is the approach …

Micrornas (Mirnas) In Neurodegenerative Diseases, Peter T. Nelson, Wang-Xia Wang, Bernard W. Rajeev

Sanders-Brown Center on Aging Faculty Publications

Aging-related neurodegenerative diseases (NDs) are the culmination of many different genetic and environmental influences. Prior studies have shown that RNAs are pathologically altered during the inexorable course of some NDs. Recent evidence suggests that microRNAs (miRNAs) may be a contributing factor in neurodegeneration. miRNAs are brain-enriched, small (~22 nucleotides) non-coding RNAs that participate in mRNA translational regulation. Although discovered in the framework of worm development, miRNAs are now appreciated to play a dynamic role in many mammalian brain-related biochemical pathways, including neuroplasticity and stress responses. Research about miRNAs in the context of neurodegeneration is accumulating rapidly, and the goal of …

Reducing Hiv/Aids In Young People In Sub-Sahara Africa: Gaps In Research And The Role Of Theory, Kristien Michielsen, Marleen Bosmans, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

This paper discusses the role of education in preventing HIV in children and young people in sub-Sahara Africa and presents the results of policy advisory research conducted on behalf of the Belgian Development Cooperation. The research consisted of a literature review and a field study in Rwanda. Relative to the high number of HIV prevention activities in sub-Sahara Africa, there is a limited number of scientific data on HIV risk reduction interventions for young people in this region. Longitudinal studies are especially scarce. Preliminary results show that many interventions have only a marginal impact on reducing sexual risk behaviour. Factors …

Successful Pregnancy Outcome Following Laparoscopic Myomectomy: Case Report, R. B. Parkar, Sikolia Wanyonyi, W. J. Kamau, D. Otieno

Obstetrics and Gynaecology, East Africa

Laparoscopic myomectomy is now widely used as an alternative to laparotomy in the management of symptomatic uterine fibroids. The advantages of this minimal access approach outweigh those of the open techniques. The pregnancy outcomes between the two methods have been studied and are comparable, but there still exists a lot of scepticism locally concerning this. It is against this background that we present a 31 year old nulliparous lady who had a two year history of primary infertility secondary to multiple uterine fibroids, the largest being fundal and measuring 6.6cm. She underwent a successful laparoscopic myomectomy in November, 2006 and …

Prevalence, Risk Factors And Outcome Of Acute Kidney Injury At The Aga Khan University Hospital Nairobi, Peter W. Munyu

Master of Medicine in Internal Medicine

Introduction: Acute kidney failure (acute kidney injury, AKI) is a group of syndromes that result in a decline in the glomerular filtration rate. In 2002, the Acute Dialysis Quality Initiative (ADQI) group proposed the RIFLE criteria to standardize the definitions of AKI severity and outcome. This criterion has been validated in several studies. AKI is frequently encountered in hospitalized patients; it has a negative impact on mortality and morbidity. A lot of work has been done to describe the epidemiology of AKI in developed countries. The same does not apply for developing countries. This study was designed to evaluate AKI …

Comparison Of Doppler Studies In Obstetrics With Fetal Outcome, Sheila Waa

Master of Medicine in Imaging and Diagnostic Radiology

Purpose: to compare umbilical artery and middle cerebral Doppler ultrasound values in normal and high risk pregnancies with fetal outcome. Method: 121 consecutive pregnancies (at or over 28 weeks gestation), stratified into low and high risk pregnancies based on clinician information were prospectively examined with doppler ultrasound of UA and MCA. Results: outcome was available for 100 of the 121 patients. 26% of pregnancies had poor outcome. Of these 73% (19) and 27% (7) were classified as high risk and low risk respectively. UA alone or in combination with MCA was shown to have 100% specificity for predicting fetal outcome. …

Sr-Bi Protects Against Endotoxemia In Mice Through Its Roles In Glucocorticoid Production And Hepatic Clearance, Lei Cai, Ailing Ji, Frederick C. De Beer, Lisa R. Tannock, Deneys R. Van Der Westhuyzen

Internal Medicine Faculty Publications

Septic shock results from an uncontrolled inflammatory response, mediated primarily by LPS. Cholesterol transport plays an important role in the host response to LPS, as LPS is neutralized by lipoproteins and adrenal cholesterol uptake is required for antiinflammatory glucocorticoid synthesis. In this study, we show that scavenger receptor B-I (SR-BI), an HDL receptor that mediates HDL cholesterol ester uptake into cells, is required for the normal antiinflammatory response to LPS-induced endotoxic shock. Despite elevated plasma HDL levels, SR-BI–null mice displayed an uncontrollable inflammatory cytokine response and a markedly higher lethality rate than control mice in response to LPS. In addition, …

Management Of The Neck In Differentiated Thyroid Cancer, David M. Cognetti, Edmund A. Pribitkin, William M. Keane

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Differentiated thyroid cancer is characterized by an excellent long-term prognosis, which unlike other head and neck carcinomas, is not influenced definitively by regional lymph node metastasis. The relative rarity of the disease, together with its tendency for delayed metastasis and its low mortality, makes a prospective randomized trial comparing treatment outcomes difficult. As a result, the effect of cervical lymph node metastases on survival is unclear, making meaningful recommendations for their management somewhat subjective. This article discusses guidelines for the management of the neck in differentiated.

Reproductive Health

The Population Council's Frontiers in Reproductive Health (FRONTIERS) program offered technical assistance to any Asia Near East (ANE) country mission interested in funding adaptation of USAID‟s “best practices” in family planning or reproductive health. The ANE Bureau provided funding for the costs of FRONTIERS technical assistance. The overall objective of this study was to replicate and scale up "best practices" based on findings from FRONTIERS. The specific objectives were to institutionalize the Systematic Screening Instrument in the entire state of Uttarakhand, India; to strenghten emergency contraceptive pills service provision in Uttarakhand, India; and to enhance the use of Lactational Amenorrhea …

Sexual And Reproductive Health Needs Of Adolescents Perinatally Infected With Hiv In Uganda, Harriet Birungi, John Frank Mugisha, Juliana K. Nyombi, Francis Obare, Humphres Evelia, Hannington Nyinkavu

Reproductive Health

In Uganda, HIV/AIDS treatment, care and support programs are still organized around either adult or pediatric care and fail to adequately address the needs of adolescents, specifically perinatally-infected adolescents. This study, implemented jointly by the Population Council's Frontiers in Reproductive Health (FRONTIERS) program and the AIDS Support Organization (TASO), aimed to better understand the reproductive health and sexuality of this population group, and to identify anxieties or fears they have around entering social stages of adulthood. This study confirms that wide programmatic gaps exist in addressing the sexual and reproductive health needs of young people perinatally infected with HIV who …

Situation Analysis Of The Integration Of Family Planning Services In Postpartum, Postabortion And Prevention Of Mother To Child Transmission Programs In Nicaragua, Freddy Solis, Ana Del Carmen Rojas, Gadea Adilia, M. Estela Rivero-Fuentes, Ricardo Vernon

Reproductive Health

Between September 2005 and April 2007, FRONTIERS and Alva, a Nicaraguan consulting firm, conducted a situation analysis of the provision and use of contraceptive services in postpartum, postabortion and prevention of mother-to-child transmission of HIV (PMTCT) programs. The project‘s objective was to assess the degree to which contraceptive services were linked to postpartum, postabortion and PMTCT services and if this allowed the programs to meet the contraceptive needs of their clients. The project proposes recommendations for improving the quality of these programs.
