Variation in reproductive characteristics of the stream frog Colostethus trinitatis on the island of Trinidad

Autor: Clive P. Cummins, Mary J. S. Swan

Publikováno v: Journal of Tropical Ecology. 11:603-618

We compared reproductive characteristics of the dendrobatid frog Colostethus trinitatis at the Tamana cave in the Central Range hills and at five forest stream sites in the Northern Range hills of Trinidad. There were significant differences between

MR diagnosis of meniscal tears: analysis of causes of errors

Autor: A A De Smet, M A Norris, J S Swan, Michael J. Tuite

Publikováno v: American Journal of Roentgenology. 163:1419-1423

MR imaging of the knee is an accurate method for diagnosing meniscal tears. However, MR findings do not always agree with surgical findings. In a retrospective study, we analyzed the various causes of incorrect MR diagnoses.We reviewed a series of 40

Generalized matched filtering for time-resolved MR angiography of pulsatile flow

Autor: David M. Weber, Thomas M. Grist, P A Turski, J S Swan, Yi Wang, F.R. Korosec, Charles A. Mistretta

Publikováno v: Magnetic Resonance in Medicine. 30:600-608

Generating flow-specific images (arteriograms, venograms) with optimal signal-to-noise ratios for time-resolved MR angiography is a conditional maximum problem, and its solutions are generalized matched filters. We have investigated six matched filte

Two forms of human milk bile-salt-stimulated lipase

Autor: J L Poechmann, M M Hoffman, J S Swan, M K Lord

Publikováno v: Biochemical Journal. 283:119-122

This study provides the first direct evidence for the existence of two active forms of the human milk enzyme bile-salt-stimulated lipase. Heparin-based affinity chromatography and size-exclusion chromatography were used to obtain two active forms of

Evaluation of Joint Disease in the Adult Hand and Wrist

Autor: Kenneth A. Buckwalter, E. M. Braunstein, J. S. Swan

Publikováno v: Scopus-Elsevier

The radiographic evaluation of joint diseases in the adult hand and wrist is described in this chapter. The main focus is on the interpretation of plain radiographs of the hands and wrists in patients with joint symptoms. After considering the genera

Effects of eicosapentaenoic acid on cardiac SR Ca(2+)-release and ryanodine receptor function

Autor: Stephen C. O’Neill, Rebecca Sitsapesan, N Negretti, J S Swan, Katharine M. Dibb

Publikováno v: Cardiovascular research. 60(2)

n-3 polyunsaturated fatty acids (PUFAs) can prevent life-threatening arrhythmias but the mechanisms responsible have not been established. There is strong evidence that part of the antiarrhythmic action of PUFAs is mediated through inhibition of the

Method for rapidly determining and reconstructing the peak arterial frame from a time-resolved CE-MRA exam

Autor: T J, Carroll, F R, Korosec, J S, Swan, T M, Grist, R, Frayne, C A, Mistretta

Publikováno v: Magnetic resonance in medicine. 44(5)

A method that determines the information necessary to reconstruct a single vascular image from a time-resolved CE-MRA exam is presented. Raw k-space data are used to approximate the time course of the contrast passage prior to image reconstruction. T
