Wavelength variation in directional sensitivity of the long- and medium-wave sensitive foveal cones of red-green dichromats
(Elsevier, 1979)
The intensity of a monochromatic light required just to detect 30 Hz flicker as the point of entry of the light was changed in 0.5 mm steps across the eye's entrance pupil and measured throughout the spectrum on 4 protanopes ...
Biosynthesis of keratan sulfate: Purification and properties of a galactosyltransferase from bovine cornea
(Elsevier, 1979-02)
A soluble galactosyltransferase was purified 22,000-fold from bovine cornea. The enzyme catalyzes the transfer of galactose from UDP-galactose to N-acetyl--glucosamine, [alpha]- and [beta]-glucosaminides, bovine cornea and ...
Cystourethrography: The effect of reservoir height upon intravesical pressure
(Springer-Verlag, 1979-03)
The effect of infusion height upon intravesical pressure during cystography was studied in three dogs and three patients. Results indicate that during bladder filling the intravesical pressure is independent of the reservoir ...
Cross-peptide bond 13C---15N coupling constants by 13C and J cross-polarization 15N NMR
(Elsevier, 1979-07)
Comparative 13C---15N coupling constants are reported for the linear dipeptide tBoc--[U-13C]Ala-[15N]GlyOMe and the corresponding cyclic diketopiperazine, both in dimethylsulfoxide (DMSO) and, upon removal of the tBoc ...
Comparative studies of wild-type and cold-mutant (temperature-sensitive) influenza viruses: Nonrandom reassortment of genes during preparation of live virus vaccine candidates by recombination at 25[deg] between recent H3N2 and H1N1 epidemic strains and cold-adapted A/Ann Arbor/6/60
(Elsevier, 1979-08)
Genetic compositions of 35 recombinant cold-adapted influenza A(H3N2 and H1N1) candidate live attenuated vaccine strains have been determined. The viruses, which had been obtained by recombination (reassortment) at 25[deg] ...
The wavelength variation of the directional sensitivity of the stiles [pi]1([mu])
(Elsevier, 1979)
The variation of the directional sensitivity of Stiles' (1953) [pi]1([mu]) mechanism was measured throughout the spectrum on one deuteranope. For wavelengths greater than about 550 nm, the directional properties measured ...
The protective effects of dietary fish oil on focal cerebral infarction
(Elsevier, 1979-11)
The protective effect of the (n-3) fatty acids in menhaden fish oil on acute cerebral ischemia was investigated in cats. Cerebral ischemia was produced by ligation of the left middle cerebral artery of cats fed either a ...
Individual behavioral responses to hypothalamic stimulation persist despite destruction of tissue surrounding electrode tip
(Elsevier, 1979-09)
Behavior evoked by hypothalamic stimulation differs among animals, although their electrode placements appear histologically to be identical. These differences have been attributed to selective activation of functionally ...
The political economy of primary care and "health by the people": An historical exploration
(Elsevier, 1979-12)
The historical development of personal health services within the Third World, as background to the current discussion of primary health care and so-called "health by the people" efforts, is reviewed. This development is ...
