Recent studies show that antagonists of growth hormone-releasing hormone (GH-RH) inhibit proliferation of various cancers indirectly through blockage of the endocrine GH-insulin-like growth factor (IGF) I axis and directly by an action on tumor cells involving the suppression of autocrine/paracrine IGF-I, IGF-II, or GH-RH. The effectiveness of therapy with GH-RH antagonist JV-1-38 and its mecha...

The aerosol survival of Escherichia coli JEPP, a particularly sensitive strain, has been studied in a nitrogen atmosphere (> 99.9 yo) when sprayed from suspension in solutions of sodium glutamate or glycerol, and collected into phosphate buffer with or without M-sucrose. The response caused by changes in relative humidity (RH) to 30% and I O O ~ ~ before collection was also examined, These two ...

To better understand the effects of ambient relative humidity (RH) on physiological variables and the implications of RH-correcting evaporative water loss (EWL) data for marsupials, we examined the effect of RH on EWL, body temperature (Tb), metabolic rate (MR) and thermal conductance (C) of the brushtail possum (Trichosurus vulpecula), a medium-sized marsupial. Correcting EWL data for 27 speci...

Density functional theory has been used to investigate the structures, bonding and properties of a family of hydride rich late transition metal clusters of the type [Rh(6)(PH(3))(6)H(12)](x) (x = 0, +1, +2, +3 or +4), [Rh(6)(PH(3))(6)H(16)](x) (x = +1 or +2) and [Rh(6)(PH(3))(6)H(14)](x) (x = 0, +1 or +2). The positions of the hydrogen atoms around the pseudo-octahedral Rh(6) core in the optimi...

Recombinant human (rh) interleukin-3 (IL-3) stimulated the proliferation and differentiation of erythroid, granulocyte, macrophage, eosinophil (Eo), and mixed colonies as well as megakaryocytes from human bone marrow cells. rh IL-3 was a weaker stimulus than rh granulocyte-macrophage colony-stimulating factor (GM-CSF) for day 14 myeloid cell colonies. At day 7 of incubation, rh IL-3 stimulated ...

The water content of human stratum corneum has been measured gravimetrically in vitro in relation to relative humidity (RH) and temperature. Water content increased with increasing RH. Stratum corneum water content increased 50% when the temperature was raised from 20 to 35 degrees C at RH below 60%. Temperature dependence decreased with increasing RH until there was essentially no temperature ...

The relative rate constants for the Rh(II)-mediated diazo decomposition of a series of para- or meta-substituted diazophenylacetates were measured through intermolecular competition. The kinetic data were further subjected to Hammett correlation analysis and were found to have better linear correlation with sigma(+). Reaction constants for four Rh(II) catalysts have been obtained, Rh(2)(OAc)(4)...

The newly invasive soybean aphid,Aphis glycinesMatsumura, has seriously threatened soybean production in North America, after having spread to 20 states in the United States and several southernprovincesofCanada.Control ofA. glycineshas focusedonapplicationsof insecticides, which are not a long-term solution to soybean aphid pest management. In autumn, soybean aphids start producing alate femal...
