Calcium sensing receptor: molecular cloning in rat and localization to nerve terminals.

We have molecularly cloned a calcium sensing receptor (CaSR) from a rat striatal cDNA library. Rat CaSR displays 92% overall homology to its bovine counterpart with seven putative transmembrane domains characteristic of the superfamily of guanine nucleotide-binding proteins and significant homology with the metabotropic glutamate receptors. Northern blot analysis reveals two transcripts in thyroid, kidney, lung, ileum, and pituitary. In brain highest regional expression of the RNA occurs in the hypothalamus and the corpus striatum. Immunohistochemistry reveals discrete punctate localizations throughout the brain that appear to be associated with nerve terminals. No staining is evident in cell bodies of neurons or glia. Cerebral arteries display an intense network of CaSR immunoreactive fibers associated with vessel innervation. CaSR on nerve terminal membranes may regulate neurotransmitter disposition in response to Ca2+ levels in the synaptic space.

A catalogue of books in the College library: [which Benjamin Welles wished to read], 1797

In this small paper-bound catalog, Benjamin Welles (1781-1860) listed books in the Harvard College Library which he wished to read. He presumably compiled the list by consulting the Library's 1790 printed catalog, as the works are categorized according to subjects outlined in that catalog (Antiquities, Astronomy, Ancient Authors, Biography, Sacred Criticism, Ethics, Geography, Geometry, History, Nature, Travels / Voyages, Natural Law, Logic, Metaphysics, Miscellaneous Works, Dramatic, Phililogy, Natural Philosophy, Poetry, Rhetoric, and Theology). The final pages of Welles' catalog, which he titles "Another Selection," list additional volumes he wished to read. These are listed alphabetically, A - G. Some titles throughout the catalog have been marked with a "+" perhaps to indicate that Welles had read them.

Letters from Benjamin Welles to John Henry Tudor, 1799-1801

Benjamin Welles wrote these six letters to his friend and classmate, John Henry Tudor, between 1799 and 1801. Four of the letters are dated, and the dates of the other two can be deduced from their contents. Welles wrote Tudor four times in September 1799, at the onset of their senior year at Harvard, in an attempt to clear up hurt feelings and false rumors that he believed had caused a chill in their friendship. The cause of the rift is never fully explained, though Welles alludes to "a viper" and "villainous hypocrite" who apparently spread rumors and fueled discord between the two friends. In one letter, Welles asserts that "College is a rascal's Elysium - or the feeling man's hell." In another he writes: "College, Tudor, is a furnace to the phlegmatic, & a Greenland to thee feeling man; it has an atmosphere which breathes contagion to the soul [...] Villains fatten here. College is the embryo of hell." Whatever their discord, the wounds were apparently eventually healed; in a letter written June 26, 1800, Welles writes to ask Tudor about his impending speech at Commencement exercises. In an October 29, 1801 letter, Welles writes to Tudor in Philadelphia (where he appears to have traveled in attempts to recover his failing health) and expresses strong wishes for his friend's recovery and return to Boston. This letter also contains news of their classmate Washington Allston's meeting with painters Henry Fuseli and Benjamin West.

The organs of internal secretion, their diseases and therapeutic application; a book for general practitioners.

"In this edition several important alterations have been made in the construction of the book. A chapter has been inserted dealing with the physiology of the internal secretions and their relationships ... The position of this chapter has necessitated the renumbering of the subsequent chapters; and two chapters have been added in later parts of the book." - Pref.

Systemic apomorphine alters HPA axis responses to interleukin-1 beta adminstration but not sound stress

Apomorphine is a dopamine receptor agonist that was recently licensed for the treatment of erectile dysfunction. However, although sexual activity can be stressful, there has been little investigation into whether treatments for erectile dysfunction affect stress responses. We have examined whether a single dose of apomorphine, sufficient to produce penile erections (50 mug/kg, i.a.), can alter basal or stress-induced plasma ACTH levels, or activity of central pathways thought to control the hypothalamic-pituitary-adrenal axis in rats. An immune challenge (interleukin-1beta, 1 mug/kg, i.a.) was used as a physical stressor while sound stress (100 dB white noise, 30 min) was used as a psychological stressor. Intravascular administration of apomorphine had no effect on basal ACTH levels but did substantially increase the number of Fos-positive amygdala and nucleus tractus solitarius catecholamine cells. Administration of apomorphine prior to immune challenge augmented the normal ACTH response to this stressor at 90 min and there was a corresponding increase in the number of Fos-positive paraventricular nucleus corticotropin-releasing factor cells, paraventricular nucleus oxytocin cells and nucleus tractus solitarius catecholamine cells. However, apomorphine treatment did not alter ACTH or Fos responses to sound stress. These data suggest that erection-inducing levels of apomorphine interfere with hypothalamic-pituitary-adrenal axis inhibitory feedback mechanisms in response to a physical stressor, but have no effect on the response to a psychological stressor. Consequently, it is likely that apomorphine acts on a hypothalamic-pituitary-adrenal axis control pathway that is unique to physical stressors. A candidate for this site of action is the nucleus tractus solitarius catecholamine cell population and, in particular, A2 noradrenergic neurons. (C) 2003 Elsevier Science Ltd. All rights reserved.
