The North Pacific Oscillation (NPO) in sea level pressure and its upper-air geopotential height signature, the west Pacific (WP) teleconnection pattern, constitute a prominent mode of winter midlatitude variability, the NPO/WP. Its mature-phase expression is identified from principal component analysis of monthly sea level pressure variability as the second leading mode just behind the Pacific–...

The title compound, Na(3)[NpO(4)(OH)(2)]·2H(2)O, contains distorted tetra-gonal-bipyramidal centrosymmetric [NpO(4)(OH)(2)](3-) complex anions. The Np-O distances are 1.8975 (7) and 1.8891 (7) Å in the NpO(4) group and 2.3451 (7) Å to the OH group. Both Na atoms (one in a general position, the second in a special position on an inversion centre) have a distorted octahedral oxygen environment.

The existence of quasi-decadal variability in the Pacific sector climate (e.g., Latif and Barnett 1994, 1996; Mantua et al. 1997; Minobe 1997) has important implications for long-range climate prediction in North America. The spatial manifestations in climate variables around the North Pacific sector associated with the North Pacific oscillation (NPO) are qualitatively similar to those of ENSO....

We present a case of neurogenic pulmonary oedema (NPO) due to subarachnoid haemorrhage that resulted in hypoxia refractory to conventional mechanical ventilation. Prone positioning was employed, resulting in rapid and sustained improvement in oxygenation. We discuss the pathogenesis of NPO and the mechanism of action of prone ventilation. Prone ventilation may be of value in the management of N...

The Web transformed the environment in which Nonprofit Organizations (NPOs) work. NPOs can now reach donors and recipients inexpensively through cyberspace. They may, however, be missing, a large, untapped clientele—people with disabilities who want to donate, volunteer, or access services of a NPO. If NPO homepages are not accessible to the growing population of people with disabilities, they ...

BACKGROUND Studies that have attempted to define the incidence of aspiration or pulmonary complications during sedation/anesthesia of children with respect to nil per os (NPO) status or other factors are difficult because of the relatively infrequent rate of these complications. METHODS The Pediatric Sedation Research Consortium consists of 42 participating institutions with elective sedation...

Hypocretin (orexin)-containing neurons in the hypothalamus, which have been implicated in the pathology of narcolepsy, project to nuclei in the brain stem reticular formation that are involved in the control of the behavioral states of sleep and wakefulness. Among these nuclei is the nucleus pontis oralis (NPO). Consequently, the present study was undertaken to determine if the hypocretinergic ...

BACKGROUND/AIMS Variation exists among anesthesia providers as to acceptable timing of NPO ("nothing by mouth") for elective colonoscopy procedures. There is a need to balance optimal colonic preparation, patient convenience, and scheduling efficiency with anesthesia safety concerns. We reviewed the evidence for the relationship between NPO timing and aspiration incidence and colonoscopy resche...

The circadian activity of the hypothalamo-pituitary-adrenal/interrenal (HPA/I) axis is crucial for maintaining vertebrate homeostasis. In mammals, both the principle regulator, corticotropin-releasing hormone (crh) in the hypothalamic paraventricular nucleus (PVN) and the final effector, the glucocorticoids show daily rhythmic patterns. While glucocorticoids are the main negative regulator of P...

OBJECTIVES We investigated the association of nil per os (NPO) status and subsequent nutritional support with patient weight and length of stay (LOS) during admission for bronchiolitis in patients <2 years old. METHODS A retrospective chart review was performed of all patients <2 years old admitted to an academic pediatric hospital between November 2009 and June 2011 with a Current Procedural...
