Identification of sperm antigens that elicit immunoglobulin (Ig) production and knowledge of their roles in sperm transport and fertilization may enhance diagnosis and treatment of immunologic infertility. Sperm antigens recognized by a female patient's serum anti-sperm antibodies were characterized using an indirect immunobead-binding test, immunoblot analysis, and immunochemical labeling. The anti-sperm antibodies' effect on sperm function was evaluated by acrosome induction by calcium ionophore. Immunobeads specific for IgG were bound to the head of 79% of motile donor sperm. Immunochemical labeling of antibody-binding sites was restricted to the plasma membrane over the acrosomal crescent. No labeling was observed on the …

Social Cognition, Empathy And Functional Outcome In Schizophrenia, Amy Sparks, S. Mcdonald, B. Lino, M. O'Donnell, M. Green
Amy E.T. Sparks
Social and occupational functioning difficulties are a characteristic feature of schizophrenia, and a growing body of evidence suggests that deficits in social cognition contribute significantly to these functional impairments. The present study sought to investigate whether the association between social cognition and social functioning in schizophrenia would be mediated by self-reported levels of empathy. Thirty outpatients with a diagnosis of schizophrenia or schizoaffective disorder, and twenty-five healthy controls completed a well-validated facial affect processing task (Ekman 60-faces facial task from the Facial Expressions of Emotion - Stimuli and Tests; FEEST), The Awareness of Social Inference Test (TASIT; to assess emotion …

Imaging Of Abdominal Aortic Aneurysms, Amy Sparks, P. Johnson, M. Meyer
Amy E.T. Sparks
Given the high rate of morbidity and mortality associated with abdominal aortic aneurysms (AAAs), accurate diagnosis and preoperative evaluation are essential for improved patient outcomes. Ultrasonography is the standard method of screening and monitoring AAAs that have not ruptured. In the past, aortography was commonly used for preoperative planning in the repair of AAAs. More recently, computed tomography (CT) has largely replaced older, more invasive methods. Recent advances in CT imaging technology, such as helical CT and CT angiography, offer significant advantages over traditional CT. These methods allow for more rapid scans and can produce three-dimensional images of the AAA …
Development Of An Immunocontraceptive Vaccine. Current Status, H. Feng, J. Sandlow, Amy Sparks, A. Sandra
Development Of An Immunocontraceptive Vaccine. Current Status, H. Feng, J. Sandlow, Amy Sparks, A. Sandra
Amy E.T. Sparks
Development of an effective and modern contraceptive vaccine is a key factor in the global issue of regional population growth as well as agricultural, medical, economic and social development. A review was done of the current medical literature concerning development of an immunocontraceptive vaccine and relative molecular biology technology. Various approaches have been taken to identify candidate-specific antigens for immunocontraceptive development, such as sperm, zona pellucida and hormonal antigens. Suppressed fertility and the reversibility of these effects on mammalian species, including humans, have been demonstrated. The successful results obtained so far support the continued investigation for an effective immunocontraceptive vaccine.

Culture Systems: Embryo Culture And Monozygotic Twinning, Amy Sparks
Amy E.T. Sparks
The incidence of monozygotic twinning in pregnancies achieved with assisted reproductive technologies (ART) is significantly higher than spontaneously conceived pregnancies. The factors associated with ART that predispose the embryos to splitting are not well-characterized. Assisted hatching and extended embryo culture are two ART laboratory methods that have been risk factors for monozygotic twinning. The methods and strategies that may be employed to avoid monozygotic twinning are discussed in this chapter.

Comparison Of Microscopic Epididymal Sperm Aspiration And Intracytoplasmic Sperm Injection/In-Vitro Fertilization With Repeat Microscopic Reconstruction Following Vasectomy: Is Second Attempt Vas Reversal Worth The Effort?, J. Donovan, M. Dibaise, Amy Sparks, J. Kessler, J. Sandlow
Amy E.T. Sparks
Since 1986, we have performed microscopic reconstruction in 18 men following failed microscopic vasectomy reversal. Between 1994 and 1996, nine couples have undergone microscopic epididymal sperm aspiration (MESA)/ intracytoplasmic sperm injection (ICSI) treatment for male infertility due either to congenital absence of the vas deferens (CAVD) or inoperable excurrent duct obstruction. We compared the cost efficiency of repeat vasectomy reversal to that for MESA combined with ICSI/in-vitro fertilization (ICSI/IVF). The cost of male partner procedures (vasectomy reversal, MESA) was based on physician and hospital charges, while the cost of ICSI/IVF included preparation of the female partner (medications and physician charges) …

'Old' Bones In Young Bodies: The Tale Of Cystic Fibrosis, Amy Sparks, S. Mcgee, C. Boone, I. Neuringer, S. Jones, R. Aris
Amy E.T. Sparks
PURPOSE OF REVIEW: Cystic fibrosis (CF) is the most common genetic disease within the white population and leads to premature respiratory failure. Approximately, 60 000 individuals are currently living with CF in North America and Europe, almost half of whom are adults. RECENT FINDINGS: Dozens of studies across the globe indicate that CF adults have low bone density and increased rates of fractures. This genesis of the problem appears to be in late childhood to adolescence. SUMMARY: Prevention and treatment of CF-related bone disease must address the myriad risk factors (decreased absorption of fat-soluble vitamins due to pancreatic insufficiency, altered …

Jennifer R Niebyl
We have investigated the clinical utility of two direct radioimmunoassays for free thyroxin, an enzyme-inhibition immunoassay, and a direct measurement of thyroxin-binding globulin (TBG) by radioassay. All assay methods correctly identified greater than or equal to 90% of euthyroid, hyperthyroid, and hypothyroid patients who had normal TBG concentrations. In patients with altered TBG concentrations, none of the assays correctly classified all categories of patients. However, the direct assays of free thyroxin concentrations were able to classify correctly more patients with altered TBG concentrations than did the free thyroxin index methods. The free thyroxin index methods evaluated may be acceptable for …
