Heart failure is a highly prevalent disorder that continues to be associated with repeated hospitalizations, high morbidity, and mortality. Sleep-related breathing disorders repetitive episodes of asphyxia may adversely affect heart function. The main aims this study were determine the prevalence, consequences, differences in various sleep-related ambulatory male patients stable failure.This article reports results prospective 81 92 eligible left ventricular ejection fraction < 45%. There 40...
The chief materials for the present investigation consist of a number embryos three common species Apteryx which have come into my possession during last or four years. For some time I only succeeded in obtaining two specimens advanced stages, and it was when fortunate enough to secure services Mr. Richard Henry, Lake Te Anau, as collector, that material became copious be worth working up. Even now observations are many respects very imperfect owing lack sufficient specimens, most important...
Theophylline has been used to treat central apnea associated with Cheyne-Stokes respiration (periodic breathing). We studied the effect of short-term oral theophylline therapy on periodic breathing stable heart failure due systolic dysfunction.Fifteen men compensated (left ventricular ejection fraction, 45 percent or less) participated in study. Their base-line polysomnograms showed breathing, more than 10 episodes and hypopnea per hour. In a double-blind crossover study, patients received...
Abstract 1 Natural and recurring disturbances caused by fire, native forest insects pathogens have interacted for millennia to create maintain forests dominated seral or pioneering species of conifers in the interior regions western United States Canada. 2 Changes fire suppression other factors last century altered composition increased density trees many forests, leading concomitant changes how these three disturbance agents interact. 3 Two‐ three‐way interactions are reviewed that involve...

The purpose of this study was 1) to determine the effects nasal O2 on periodic breathing, arterial oxyhemoglobin desaturation and nocturnal ventricular arrhythmias in patients with heart failure 2) characteristics whose breathing will be reversed by administration; our hypothesis that more severe desaturation, respond favorably oxygen. Prospective Referral sleep laboratory a Department Veterans Affairs Medical Center. 36 ambulatory male initial polysomnograms showed fifteen or episodes apnea...
Since communicating my previous observations on this subject to the Royal Society (1), I have received from collector (R. Henry) whom owe most of material, three embryos Apteryx austrlis , which fill important gaps in series developmental stages formerly studied, and serve correct one or two erroneous conclusions was led by having, so many cases, only a single specimen each stage. The youngest is as nearly possible intermediate age between Stages E F former paper: shall speak it Stage E'....
<em>The Bulletin of the Ecological Society America</em> is official record business America, publishing non-refereed articles that cover ecological events, news and reports.
The materials for the present investigation consist of embryos three common species Apteryx , viz., A. australis, oweni and mantelli . Most them, including all earlier stages, were collected me by Mr. R. Henry, Lake Te Anau; a nearly ripe embryo was obtained from Reischek: I am indebted to Mme. Müller half-ripe specimen Sir Walter Buffer two, somewhat older, desire record my sincere thanks Council Royal Society grant which has enabled defray expenses investigation.
The few observations I have to offer on this much-discussed subject are partly confirmatory of, supplementary to, those of Kleinenberg, they present a certain agreement with F. E. Schulze, while are, in great measure, distinctly contradictory the later researches Korotneff. 1.

[Note by W. K. P.—This is not the first, but it most important, of “Notes” sent to me my son, on development this, lowest and Reptilian all birds known. Seven stages before hatching have been obtained, will yield, I am satisfied, instructive results and, added what has already done in other forms Ratitæ, give something like completeness our knowledge morphology these archaic types. It merely as low kinds that Struthious types are so important biologist; they intimately related more primitive...
