    Neural mechanisms by which gravitational stimuli and stress affect the secretion of renin and other hormones

    The present goal is to determine by the production of discrete lesions the parts of the hypothalamus and brainstem that are involved in serotonin-mediated increases in renin secretion. A variety of stimuli which act in different ways to increase renin stimuli were developed and standardized. The experiments with p-chloroamphetamine (PCA) demonstrated that there is a serotonergic pathway which projects from the dorsal raphe nuclei to the paraventricular nuclei and the vetromedial nuclei of the hypothalamus; that projection from paraventricular nuclei to the brainstem and spinal cord may be oxytocinergic; and that the pathway from the spinal cord to the renin secreting cells is sympathetic. The demonstration that paraventicular lesions lower circulating renin substrate is important because it raises the possibility that substrate secretion is under neural control, either via the pituitary or by direct neural pathways. The discovery that lesions of the ventromedial nuclei appear to abolish the increase in renin secretion produced by many different stimuli without affecting the concentration of renin substrate in the plasma makes the position of the hypothalamus in the regulation of fluid and electrolyte balance more prominent than previously suspected

    On and On until All Out : Seeking Silence within the Postmodern Paradigm of Samuel Beckett

    In his biography of Samuel Beckett\u27s life, James Knowlson writes that Beckett failed miserably as a teacher; had Beckett not failed, he would have spent his life as a scholar, teaching and writing brilliant essays like his award winning Proust study. The sizable amount of literature on Beckett\u27s creative writing, however, seems to indicate that Beckett\u27s pedagogic failure metamorphosed into a dazzling success for the humanity, which so frequently themes his work, through literature. Yet, some groups, proponents of Christianity in particular, might have preferred for Beckett\u27s influence to have trickled through the one or two schools in which he might have taught rather than to have flooded classrooms from Japan to Midwestern America, simply because the prototypical postmodern world of his work seemingly rejects the fundamental tenets of societies that ingest chicken after church as easily as the equally fatty truths obtained from the pulpit. Beckett\u27s world, as Andrew Kennedy writes, is characterized by the sense of a cosmic run-down, the loss of the human sense of the divine, and the breakdown of language itself , realities diametrically opposed to ideas like Heart for God, mind for truth, friends for life, and service for eternity, the motto of an absolute-abiding liberal arts university in Ohio (Cedarville University Home Page). In light such absolute ideals, it is little wonder that proponents of Christianity find authors like Beckett difficult to swallow. Yet, if any group of beliefs could resonate with a writer like Beckett, it would seem that Christianity, with its emphasis in passages like John 1 and Philippians 2 on form and content, or as Abbot terms them, structure and meaning, two concepts with which Beckett wrestled his entire life would most dynamically speak to his work. And perhaps by critically assessing Beckett\u27s world, Christians and others will find something underneath the muck of postmodernism sufficiently solid to prolong living in Murphy, to support a journey in How it is, and, eventually, to nourish a tree in Waiting for Godot. In each of these works, Beckett presents silence within the temporary postmodern paradigm as humanity\u27s only reprieve from its own condition

    Research Informed Guidelines for Couple and Relationship Education Programs with Arab American Immigrant Couples

    Get PDF
    In this paper, we review the characteristics of Arab immigrants and propose guidelines for couple and relationship education (CRE) programs with Arab immigrant couples. Arab immigrants are a heterogeneous group, yet they share common cultural characteristics and family values that are essential to understand when working with them. Generally, CRE programs with immigrated Arabs should be mindful of (1) strongly valued religious beliefs, (2) extended family as a primary source of support and marital problem-solving, (3) the tendency to follow gender-based roles and responsibilities, and (4) Arabic language and communication norms. Family educators and practitioners who work with recently immigrated Arab couples should familiarize themselves with these characteristics to better serve them

    Stepparent-Child Relationship Quality and Couple Relationship Quality: Stepfamily Household Type as a Moderating Influence

    Get PDF
    Stepparent–child relationships and new couple relationships are core pillars of stepfamily functioning and well-being. Although research generally indicates that stepparent–child relationship quality and couple relationship quality are positively associated, questions remain about in which contexts and from whose perspective this association holds. Using reports from parents and stepparents in a sample of 291 stepfamily heterosexual couples, we assess whether stepfamily household type (i.e., mother–stepfather, father–stepmother) moderates the association between stepparent–child relationship quality and couple relationship quality. Results indicate that stepparent–child relationship quality and couple relationship quality are positively associated in both mother–stepfather and father–stepmother families, and from the vantage point of both parents and stepparents. The positive association is significantly larger in mother–stepfather families from the vantage point of stepfathers. Implications for future research and practice with stepfamilies are discussed

    What are the Effects of Raw vs. Pasteurized Milk Consumption on Growth Rate and Fertility in a Colony of Mice?

    Get PDF
    Interest in consuming unprocessed foods has led to assumptions that raw milk has health benefits over pasteurized milk. This study was designed to evaluate the belief that raw milk is nutritionally superior. Eighteen mice were randomly assigned to one of two groups: raw milk or pasteurized milk. Mice were grouped into breeding trios and given a fresh supply of milk every four hours between 7 a.m. and 11 p.m. for 55 days. Milk consumption was tracked at each feeding by measuring the amount of milk that was provided and the amount of milk that was left from the previous feeding. The College of St. Benedict Institutional Animal Care and Use Committee (IACUC) approved this study. On average, the mice in the raw milk group consumed significantly less milk but gained the same amount of weight as the pasteurized milk group. The rate of growth per gram of milk consumed was greater in the raw milk group, but the difference did not reach statistical significance. Lastly, there was no statistical difference between the groups with regard to birth rates or pup mortality rates. Due to the limited number of mice, the positive trend in data did not reach statistical significance. A similar study done on a larger scale could produce significant results. In conclusion, this study does not demonstrate that either milk type is statistically superior in nutritional value
