To Compare The Total Cholesterol And Hdl-Cholesterol Before And After Ultra-Centrifugation In Lipemic Samples, Jawaid Jabbar, Imran Siddiqui, Syed Qaiser Raza, Ayaz Baig

Department of Pathology and Laboratory Medicine

Objective: It is an everyday routine in laboratories to encounter interference in the analysis of lipids. These likely interferences (hemolysis, icterus and lipemia) are countered by asking physicians and patients to send fresh and properly collected samples. At the Aga Khan University (AKU) Laboratory, we receive 2-3 lipemic/turbid samples per day. Previously it was our departmental policy to advise these patients to go for lipoprotein electrophoresis, which though accurate was time consuming and not cost effective. We therefore studied ultra centrifugation/airfuge as an alternate method to clear lipid interference and provide accurate, reliable and cost effective results.
Methods: Daily 2-3 …

Cart: An Hrs/Actinin-4/Berp/Myosin V Protein Complex Required For Efficient Receptor Recycling, Qing Yan, Wei Sun, Pekka Kujala, Yasmin Lotfi, Thomas A Vida, Andrew J Bean

Faculty, Staff and Student Publications

Altering the number of surface receptors can rapidly modulate cellular responses to extracellular signals. Some receptors, like the transferrin receptor (TfR), are constitutively internalized and recycled to the plasma membrane. Other receptors, like the epidermal growth factor receptor (EGFR), are internalized after ligand binding and then ultimately degraded in the lysosome. Routing internalized receptors to different destinations suggests that distinct molecular mechanisms may direct their movement. Here, we report that the endosome-associated protein hrs is a subunit of a protein complex containing actinin-4, BERP, and myosin V that is necessary for efficient TfR recycling but not for EGFR degradation. The …

Bench-To-Bedside Review: Rhabdomyolysis -- An Overview For Clinicians., Ana L Huerta-Alardín, Joseph Varon, Paul E Marik

Jefferson Hospital Staff Papers and Presentations

Rhabdomyolysis ranges from an asymptomatic illness with elevation in the creatine kinase level to a life-threatening condition associated with extreme elevations in creatine kinase, electrolyte imbalances, acute renal failure and disseminated intravascular coagulation. Muscular trauma is the most common cause of rhabdomyolysis. Less common causes include muscle enzyme deficiencies, electrolyte abnormalities, infectious causes, drugs, toxins and endocrinopathies. Weakness, myalgia and tea-colored urine are the main clinical manifestations. The most sensitive laboratory finding of muscle injury is an elevated plasma creatine kinase level. The management of patients with rhabdomyolysis includes early vigorous hydration.

Mechanisms Of Cell Death Initiated In Herpes Simplex Virus Thymidine Kinase Expressing Colon Tumor Cells Treated With Ganciclovir And Ucn-01, Christina Elizabeth Ahn

Theses and Dissertations in Biomedical Sciences

Metastatic colon carcinoma is the second leading cause of death from malignancy in the United States, and development of more effective treatments is essential. Heterologous expression of Herpes Simplex Virus Thymidine Kinase (HSVtk) in combination with the prodrug, ganciclovir (GCV), has shown great promise for the genetic therapy of many cancers, but most patients have had only a partial or minimal response to the therapy. After screening a panel of two drug combinations, our laboratory has shown that the combination of GCV and the protein kinase inhibitor UCN-01 (7-hydroxystaurosporine) enhances tumor cell death more effectively than either drug alone. However …

Attributional Styles Of Women Who Quit Or Reduce Smoking In The Antepartum, Patricia T. Alpert

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Researchers in the field of smoking have sought to identify variables that predict whether or not pregnant smokers stop or continue to smoke. Most variables examined are demographic in nature and little is known about psychological variables associated with those who quit or reduce smoking while pregnant.

Purpose: To analyze attributional style and locus of control to determine which factors alone, or in combination, are associated with quitting versus reduced smoking among pregnant smokers.

Methodology: Pregnant smokers who quit (n = 66) or reduced their smoking (n = 43) were identified by the nursing staff at a women’s county …

Screening For Diseases In Family Practice, Ali Khan Khuwaja, Nadya Khan Khuwaja

Department of Family Medicine

The active check-over for disease among apparently healthy people is a fundamental aspect of prevention. This is perceivable by screening, which is a search of unrecognized disease or condition by means of rapidly applied test, examination or other procedures in apparently healthy individuals. This is carried out in the hope that earlier diagnosis and subsequent management favorably alters the natural history of the disease in a significant proportion of those who are identified as 'test-positive'. Family Practitioners have privilege to provide comprehensive and holistic health care services including preventive, curative and rehabilitative on continuous and long-term basis to all members …

Multiple Metabolic Hits Converge On Cd36 As Novel Mediator Of Tubular Epithelial Apoptosis In Diabetic Nephropathy., Katalin Susztak, Emilio Ciccone, Peter Mccue, Kumar Sharma, Erwin P Böttinger

Department of Medicine Faculty Papers

BACKGROUND: Diabetic nephropathy (DNP) is a common complication of type 1 and type 2 diabetes mellitus and the most common cause of kidney failure. While DNP manifests with albuminuria and diabetic glomerulopathy, its progression correlates best with tubular epithelial degeneration (TED) and interstitial fibrosis. However, mechanisms leading to TED in DNP remain poorly understood.

METHODS AND FINDINGS: We found that expression of scavenger receptor CD36 coincided with proximal tubular epithelial cell (PTEC) apoptosis and TED specifically in human DNP. High glucose stimulated cell surface expression of CD36 in PTECs. CD36 expression was necessary and sufficient to mediate PTEC apoptosis induced …

Early Oral-Motor Interventions For Pediatric Feeding Problems: What, When And How, C. J. Manno, C. Fox, P. S. Eicher, Mary Louise Kerwin

College of Science & Mathematics Departmental Research

Children with developmental delays often have feeding difficulties resulting from oral-motor problems. Based on both clinical experience and a review of published studies, oral-motor interventions have been shown to be effective in improving the oral function of preterm infants and children with neuromotor disorders, such as cerebral palsy. However, oral-motor problems may be under identified in other populations of children with developmental difficulties. The purpose of this paper is to provide a conceptual framework for understanding oral-motor skill development and problems that can occur in any infant and young child and to review oral-motor treatment techniques and their empirical support.

On The Utility Of Stochastic Models Of Chronic Obstructive Pulmonary Disease, Rebecca Boehm

MUSC Theses and Dissertations

Chronic obstructive pulmonary disease (COPD) is a progressive and irreversible lung disease characterized by reduced lung function, abnormal inflammatory response, dyspnea, increased sputum production, and costly and debilitating exacerbations. Common treatments for COPD include smoking cessation therapy, short- and long-acting bronchodilators, inhaled corticosteroids, pulmonary rehabilitation, and home oxygen therapy. However, a recent meta-analysis demonstrated that inhaled corticosteroids fail to slow the decline in FEV1, the primary clinical marker of COPD progression. In addition, some evidence exists to suggest that long-term inhaled corticosteroid use may increase bone density loss, leading to osteoporosis. Given that the bone health effects of inhaled corticosteroid …

A Preliminary Study Of 24-Hour Post-Cesarean Patient Controlled Analgesia: Postoperative Pain Reports And Morphine Requests/Utilization Are Greater In Abstaining Smokers Than Non-Smokers, Alan P. Marco, Mark K. Greenwald, Michael S. Higgins

Anesthesiology Faculty Publications

Previous clinical studies have not examined the relationship between nicotine abstinence and opioid use for postoperative analgesia. This may be important because tobacco smokers are routinely required to abstain from smoking just before and during acute post-surgical recovery. This study investigated IV morphine self-administration [patient controlled analgesia (PCA)], subjective pain/drug effects and other measures during post-operative (elective Cesarean section) recovery.

These preliminary data suggest that a history of nicotine use and/or short-term nicotine abstinence can modulate morphine use and analgesia during post-operative recovery. These procedures provide a model for studying patterns and determinants of analgesic self-administration in medical settings.

Efficacy And Safety Of Artemether-Lumefantrine (Coartem®) Tablets (Six-Dose Regimen) In African Infants And Children With Acute, Uncomplicated Falciparum Malaria, C. Falade, M. Makanga, Zul Premji, C.E. Ortmann, M. Stockmeyer, P. Ibarra De Palacios

Pathology, East Africa

Approximately one million children die from malaria each year. A recently approved artemisinin-based tablet, Coartem (co-artemether), comprising artemether 120 mg plus lumefantrine 20 mg, given in four doses, provides effective antimalarial treatment for children in many sub-Saharan countries. However, this regimen is considered insufficient for non-immune infants and in areas where multidrug-resistant Plasmodium falciparum predominates. This open-label study assessed the efficacy and safety of co-artemether administered to 310 African children weighing 5-25 kg, with acute, uncomplicated falciparum malaria. Six doses of co-artemether were given over 3 days, with follow-up at 7, 14 and 28 days. Treatment rapidly cleared parasitemia and …

Deference, Denial, And Exclusion: Men Talk About Contraception And Unintended Pregnancy, Scott D. Johnson, Lindy B. Williams

Rhetoric and Communication Studies Faculty Publications

Individual in-depth interviews were conducted with 20 men, ages 21-48, who have fathered at least one unintended pregnancy. The goal of the interviews was to explore the experiences of these men with unintended pregnancy, their communication with partners and others, contraceptive beliefs and practices, their relationships with their partners, and the outcomes and consequences of the unintended pregnancies. This essay describes results derived from their comments regarding their contraceptive practices and the pregnancy-outcome decisions, with thematic analysis used to identify prominent themes from participant comments. Two strong themes, "deference" and "denial," and one lesser theme, "exclusion," emerged from participant responses. …

Heart Rate Variability In Non-Apneic Snorers And Controls Before And After Continuous Positive Airway Pressure, Gregory J. Gates, Susan E. Mateika, Jason H. Mateika

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

We hypothesized that sympathetic nervous system activity (SNSA) is increased and parasympathetic nervous system activity (PNSA) is decreased during non-rapid eye movement (NREM) sleep in non-apneic, otherwise healthy, snoring individuals compared to control. Moreover, we hypothesized that these alterations in snoring individuals would be more evident during non-snoring than snoring when compared to control.

Methods

To test these hypotheses, heart rate variability was used to measure PNSA and SNSA in 11 normotensive non-apneic snorers and 12 control subjects before and 7-days after adapting to nasal continuous positive airway pressure (nCPAP).

Results

Our results showed that SNSA was increased …

The Role Of Aromatase Inhibitors In Ameliorating Deleterious Effects Of Ovarian Stimulation On Outcome Of Infertility Treatment, Mohamed Fm Mitwally, Robert F. Casper, Michael P. Diamond

Wayne State University Associated BioMed Central Scholarship

Abstract

Clinical utilization of ovulation stimulation to facilitate the ability of a couple to conceive has not only provided a valuable therapeutic approach, but has also yielded extensive information on the physiology of ovarian follicular recruitment, endometrial receptivity and early embryo competency. One of the consequences of the use of fertility enhancing agents for ovarian stimulation has been the creation of a hyperestrogenic state, which may influence each of these parameters. Use of aromatase inhibitors reduces hyperestrogenism inevitably attained during ovarian stimulation. In addition, the adjunct use of aromatase inhibitors during ovarian stimulation reduces amount of gonadotropins required for optimum …
