    A multi-tiered approach was used to evaluate killifish (Fundulus heteroclitus) health by examining a suite of biomarkers in killifish inhabiting the heavily industrialized Newark Bay and a reference population in Tuckerton, NJ. The general hypothesis of this study was that Newark Bay killifish would exhibit biomarker responses indicative of impaired health when compared to a reference population from Tuckerton, NJ. The biomarkers investigated included classical endpoints (histopathology, morphometrics, gonad maturation), hepatic mRNA expression (CYP1A, metallothionein, vitellogenin I), gonadal aromatase mRNA expression, hepatic protein levels (CYP1A and vitellogenin I) and chemical exposure analyses (bile PAHs). Newark Bay fish had significantly higher levels of bile PAHs compared to reference fish. Females had significantly higher concentrations of naphthalene, pyrene and benzo[a]pyrene (3, 6 and 4 fold higher, respectively, p<0.05). Males had significantly higher concentrations of pyrene (7-fold higher, p<0.05), and higher concentrations of naphthalene (4-fold higher, p=0.06) and benzo[a]pyrene (9-fold higher, p=0.07). Histological lesions of the liver and pancreas in Newark Bay fish were similar to reference fish. Newark Bay fish had significantly higher expression of hepatic CYP1A for both males and females (7 and 3 fold higher, respectively, p<0.05) and CYP1A protein levels for both males and females (5 and 8 fold higher, p<0.05). Endocrine disruption in male gonads is demonstrated by a decreased gonad weight, altered testis development and upregulated aromatase expression (3-fold, p<0.05), which indicates exposure to endocrine active compounds. Efforts to strip spawn Newark Bay females produced few viable eggs, while at the same time Tuckerton females produced large numbers of viable eggs. There was a significant increase in the percent of pre-vitellogenic follicles (43% at Tuckerton, 64% at Newark Bay) and a significantly decreased percent of follicles at the mid-vitellogenic and mature stages (25% at Tuckerton, 3% at Newark Bay) in Newark Bay females (p<0.05). Vitellogenin mRNA and protein (egg yolk-protein) was significantly decreased in Newark Bay females (6-fold lower mRNA, 27-fold lower protein, p<0.05) while gonadal aromatase (produces 17β-estradiol) was significantly increased (210-fold higher, p<0.05). Killifish in the NY-NJ Harbor Estuary are exposed to high amounts of PAHs and aryl hydrocarbon agonists and their reproductive health is impaired. Impaired reproductive health is possibly due to disruption of steroid signaling by aryl hydrocarbon receptor-estrogen receptor crosstalk leading to decreased vitellogenin production.M.S.Includes bibliographical references (p. 91-100)by Sean M.

    Contaminant effects on vitellogenesis and oogenesis in zebrafish (danio rerio) and killifish (fundulus heteroclitus) from the chemically impacted Newark Bay, NJ

    Vitellogenins are large glycolipoprotein precursors to yolk–proteins that act as vital biomolecules and growth substrate in developing oocytes of teleosts and are synthesized exclusively in the liver. The studies in this Dissertation tested the general hypothesis that aryl hydrocarbon receptor agonist contaminants in Newark Bay, NJ down–regulate hepatic vitellogenin synthesis, resulting in inhibition of oogenesis and reproductive dysfunction. This hypothesis was examined using a variety of studies with a field population of killifish (Fundulus heteroclitus) from the contaminated Newark Bay and relatively clean Tuckerton, NJ, and using lab studies with zebrafish (Danio rerio) as a model teleost. In killifish native to Newark Bay, inhibition of oocyte yolk–development resulted in decreased egg production, decreased embryo mass and reduced yolk–volume. The cause of these effects was shown to be the down–regulation of vitellogenesis in the liver. Decreased vitellogenin expression during spawning was demonstrated to be due to deficient levels of circulating 17β–estradiol, and a decreased sensitivity of the vitellogenin pathway to induction (protein and mRNA levels) by physiological doses of 17β–estradiol. In the Newark Bay population, vitellogenin expression was inversely correlated with CYP1A, a biomarker for aryl hydrocarbon receptor 2 (AhR2) activity. I therefore propose that the down–regulation of the vitellogenin pathway is phenotypic of aryl hydrocarbon receptor mediated cross–talk inhibition of the estrogen receptor (ER). The role of AhR2 in mediating AhR–ER cross–talk inhibition of vitellogenin was examined using the zebrafish as a model teleost. The potent AhR agonists 2,3,7,8–tetrachlorodibenzo–p–dioxin and 1,2,3,7,8–pentachlorodibenzo–p–dioxin were found to inhibit the induction of vitellogenins 1, 2 and 3 by 17α–ethynylestradiol in zebrafish. Transient knock–down of AhR2 levels showed that the AhR2 mediates inhibition of vitellogenesis by 2,3,7,8–tetrachlorodibenzo–p–dioxin, demonstrating that AhR2 activation plays a role in AhR–ER cross–talk. Taken together, these studies demonstrated that the contaminant induced down–regulation of vitellogenesis in the liver can cause reproductive dysfunction in the ovary and that the mechanism for these effects is mediated through AhR2–ER signaling pathways.Ph.

    Some coastel region at Bugel are as sand-dunes. Characteristics of the dunes are sand-textured soils, single grained structure, water holding capacity and the status of low fertility, high evaporation, and the strong sea wind. The addition of manure is believed to improve the nature of physics, chemistry and biology of the soil, therefore, a study used carried out to determine the effect of manure of cattle, goats, and chickens on growth and yield of three cultivars of mung bean (Vigna radiata L. Wilczek). The study was conducted at coastel Bugel, Yogyakarta in September-December 2013. The field experiment was designed as Complete Randomized Block Design (RCBD) with two factors. The first factor is the type of manure and the second factor as kind varieties (Vima-1, Murai, Kenari). The observed data at analyzed using analysis of variance (ANOVA) with the level of credibility at 5 %. If the results of the analysis of variance are significantly different formatting as between than followed by Duncan's Multiple Range Test (DMRT) at 5% level of confidence. To determine the relationship between parameters used in this study followed the correlation analysis. The results showed that the addition of goat manure could increase the vegetative growth of green bean plants. Chicken manure treatment resulted in seed weight per hectare higher at 1,84 tons per hectare compared to goat manure, cow manure and control. Murai cultivars have better vegetative growth than of most cultivars Vima-1 and Kenari. Kenari green bean cultivars capable of producing weight seeds per acre with the highest weight at 1,83 tons per hectare compared to cultivars Vima-1 and Murai

    An evaluation study: an examination of the impact of noninvasive interventions by social workers on successful pain management among hospice clients

    This study evaluated the effectiveness of using noninvasive intervention strategies, as administered by a social work practitioner, to enhance successful pain management among the hospice client population. The study was based on the assumption that successful pain management among hospice clients is dependent upon noninvasive social work interventions for three reasons: a) not all sensations of pain can be successfully addressed by invasive medical, pharmaceutical interventions; b) noninvasive interventions of social workers are 'self- empowering,' reinforcing the client's full control of self, environment, treatment, and death; and c) theory and practice methods for noninvasive strategies are grounded in a general systems theory paradigm. A 'B,' intervention only design was used. The questionnaire was created by the researcher and administered by four interviewers to a select group of hospice clients in the Atlanta Metropolitan area. Descriptive analysis was used to see if successful pain management was improved by the intervention of noninvasive strategies. The researcher found that noninvasive interventions of social workers have a moderate impact on successful pain management among the hospice client population. The conclusions drawn from the findings suggest that the approach taken by social workers, to give palliative care by addressing the psychosocial concerns of the client, maybe a valuable component of the interdisciplinary hospice team and clearly warrants more research
