background: the nucleus raphe magnus (nrm) is involved in thermoregulatory processing. there is a correlation between changes in the firing rates of the cells in the nrm and the application of the peripheral thermal stimulus. introduction: we examined the effect of reversible inactivation and excitation of nrm on mechanisms involved in tail blood flow (tbf) regulation in hypothermia. methods: h...

objective(s): nucleus raphe magnus (nrm) that is involved in the regulation of body temperature contains nitric oxide (no) synthase. considering the effect of no on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. materials and methods: to this end, tail blood flow of male wistar rats was measured by laser doppler following the induction of ...

Reduced-intensity conditioning (RIC) regimens were initially introduced to provide allogeneic stem cell transplantation (HCT), a potentially curative procedure for myeloid malignancies, for patients who were not considered eligible for conventional myeloablative HCT either because of advanced age or excessive comorbidities. A variety of RIC regimens have been studied. The exact definition of RI...

Environmental Decision Support Systems (EDSS) are one of a suite of tools that natural resource management (NRM) practitioners may use to support the development of, or help report on the success, of NRM programs. This paper outlines two DSS that are being developed for state government or NRM agencies in Australia to assist them to develop, implement and manage programs aimed at improving reso...

It has been shown previously that the muscarinic cholinergic system in the nucleus raphe magnus (NRM) is involved in the modulation of nociception. In this study, we examined the direct actions of muscarine on the NRM neurons in a slice preparation. Muscarine (1-30 microM) produced a dose-dependent hyperpolarization in a subpopulation of the NRM cells that contain 5-hydroxytryptamine (5-HT). In...

Environmental targets are often used in planning for sustainable agricultural landscapes but their impacts are rarely known. In this paper we introduce landscape futures analysis as a method which combines linear programming optimisation with scenario analysis in quantifying the environmental, economic, and social impacts associated with achieving environmental targets, on a landscape scale. We...

To investigate the acquisition mechanism of high and stable natural remanent magnetization (NRM) in rocks of the Russell Belt, Adirondack Mountains, New York, we examined the exsolution microstructures and compositions of magnetic minerals using three samples with different magnetic properties. The samples contain titanohematite with ilmenite lamellae, end-member hematite without lamellae and r...

introduction: the antinociceptive effect of morphine is, in part, mediated through the activation of a descending pathway. one of the major components of this pathway is the nucleus raphe magnus (nrm). our previous study demonstrated the involvement of nrm in the analgesic effect of morphine microinjected into the nucleus cuneiformis (ncf) in a descending manner. the aim of the current study wa...

allogeneic hematopoietic stem cell transplantation (hsct) is the most effective therapy to prevent relapse in acute lymphocytic leukemia (all). this benefit is affected by non-relapse mortality (nrm) due to complications such as graft versus host disease (gvhd). a new approach in analyzing time-dependent covariates in competing risks is landmark analysis. so, the aim of this study is to evaluat...

The combined horseradish peroxidase retrograde transport-peroxidase-antiperoxidase immunohistochemical procedure was utilized in the present study to ascertain the sites of origin of serotonin and neurotensin projections to the rodent nucleus raphe magnus. The major serotonin inputs to the raphe magnus arise from the B-8 and B-9 groups of Dahlstrom and Fuxe (Dahlstrom, A., and K. Fuxe (1964) Ac...
