The Gastrointestinal Circulation
Annual Review of Physiology, 1968Research on the gastrointestinal circulation, particularly the developments of the last 5 years, is reviewed in this article . Older surveys document earlier work. H In general, new discoveries in this field relate to the normal structure and function of the gastrointestinal circulation, to its abnormalities and diseases, or to drugs active in the ...

Evaluation of the pulmonary vasculature is mainly indicated in patients with suspected pulmonary thromboembolism. The routine procedure so far is ventilation-perfusion scintigraphy alone or in combination with diagnostic assessment of the legs to rule out deep venous thrombosis. The results are still not reliable for the majority of patients.

On circulant and two-circulant weighing matrices.
Australas. J Comb., 2010We employ theoretical and computational techniques to construct new weighing matrices constructed from two circulants. In particular, we con- struct W (148, 144), W (152, 144), W (156, 144) which are listed as open in the second edition of the Handbook of Combinatorial Designs.

AbstractAccumulating data on the human fetal circulation shows the similarity to the experimental animal physiology, but with important differences. The human fetus seems to circulate less blood through the placenta, shunt less through the ductus venosus and foramen ovale, but direct more blood through the lungs than the fetal sheep. However, there are

THE HISTORY of the pulmonary circulation provides a measure of man's thinking about himself and his place in the universe. For centuries before De Motu Cordis in 1628, 1 the blood vessels of the lungs were incorporated into an elaborate scheme that explained the origin and distribution of spirits that animated and sustained the human being.

Nature, 1947
MOST text-books of elementary zoology contain an account of the circulation of the frog. These accounts, which are based largely on the views of Brucke1 and Sabatier2, differ in minor details, but agree that the frog's heart, though possessing only a single ventricle, functions, nevertheless, so that the so-called arterial blood, returning by the ...

For this essay which I plan will perhaps shed light upon the structure of the kidney. Do not stop to question whether these ideas are new or old, but ask, more properly, whether they harmonize with Nature. And be assured of this one thing, that I never reached my idea of the structure of the kidney by the aid of books, but by the long, patient, and ...

Circulation Increases Circulation
Read as a claim about speed, "more ions in circulation increases circulation" is weak. Read as a loop, it is exact: a carrier amplifies the flow that carries it. That loop is literally the same in two places that share no mechanism — a spark and the bloodstream — and it is the shape of this site's own thesis.openaire +1 more source
