Here we describe effects of neuroactive peptides, vasopressin, vasopressin fragment, and its analog, NC-1900, on cognitive functions and CO2-induced amnesia. Vasopressin (AVP1-9) and its fragments are synthesized in the central nervous, and it is well known to regulate diuretic action. However, vasopressin receptors are distributed not only in the supraoptic nucleus and the paraventricular nucl...

Mexicans required the stimulus of the influenza epidemic of 1918 before they established a state board of health. He describes the efforts to eradicate malaria between 1923 and 1947, and the contemporaneous success in reducing high infant and maternal death rates. After analysing changes in physician supply and distribution since statehood, Spidle concludes with an analysis ofthe growth of boar...

We measured the period and spin-down rate for SGR 1900+14 during the quiescient period two years before the recent interval of renewed burst activity. We have shown that the spin-down age of SGR 1900+14 is consistent with a braking index of ∼1 which is appropriate for wind torques and not magnetic dipole radiation. We have shown that a combination of dipole radiation, and wind luminosity, coupl...

A bayesian analysis of the world's p(γ,K^+)Λ data is presented. From the proposed selection of 11 resonances, we find that the following nucleon resonances have the highest probability of contributing to the reaction: S11(1535), S11(1650), F15(1680), P13(1720), D13(1900), P13(1900), P11(1900), and F15(2000). We adopt a Regge-plus-resonance framework featuring consistent couplings for nucleon re...

To explore the intracellular pathways activated by vasopressin receptors, the effects of arginine vasopressin (AVP) and its analogues mediating glycine (Gly)-induced Cl(-) currents (I(Gly)) were examined in acutely dissociated rat hippocampal CA1 neurons using the whole-cell patch recording technique. AVP and its analogues inhibited I(Gly) in a concentration-dependent manner. The inhibitory act...
