Determination of Gases in Sediments

Reeburgh, WS (1968)
A method was developed for sampling and analysis of gases contained in interstitial water. Interstitial water was separated from sediments with a filter press-type sediment squeezer and transferred to a specially designed sampler-stripper. Gases contained in the interstitial water were stripped from solution and analyzed by gas chromatography. Argon, N2, and CH4have been measured in sediments. The technique can be used to measure total CO2and H2S with minor modifications. © 1968, American Che...

The purification and some properties of a β-lactamase (cephalosporinase) synthesized by Enterobacter cloacae

Hennessey, T. D.; Richmond, M. H. (1968)
1. A β-lactamase has been purified from a strain of Enterobacter cloacae. 2. This enzyme is about eighty times as active against cephaloridine as against benzylpenicillin or ampicillin. 3. The enzyme has a net positive charge at pH8·0 and a molecular weight of about 14000. 4. An approximate amino acid composition of the enzyme is reported.

Electrical Transmission at the Nexus between Smooth Muscle Cells

Barr, L.; Berger, W.; Dewey, M. M. (1968)
The hypothesis that nexuses between cells are responsible for the core conductor properties of tissues was tested using smooth muscle preparations from the taenia coli of guinea pigs. Action potentials recorded from small diameter preparations across a sucrose gap change from monophasic to diphasic when a shunt resistor is connected across the gap. This indicates that transmission between smooth muscle cells is electrical, because the resistor only allows current to flow. Nexal fusion of cell...

Use of Dexamethasone in Cerebral Malaria

Woodruff, A. W.; Dickinson, C. J. (1968)
In a man who had been in a coma for 24 hours with cerebral malaria dexamethasone had a dramatic, and probably life-saving, effect. We believe dexamethasone should be given routinely, together with antimalarial therapy, to patients with cerebral malaria.

On Nonleptonic Decays : A Possible Scheme for J^+J-Type Weak Interaction Picture

Shin-ya, FURUI; Tetsuya, TSUCHIDA; Kanji, FUJII; Shoichiro, KAWASAKI; Department of Physics, Ibaraki University; Department of Physics, Ibaraki University; Department of Physics, Faculty of Science Hokkaido University; Department of Physics, College of Arts and Science Chiba University (1968)
A possible interrelation between ordinary current×current (J^+J-type) picture and phenomenological two-body weak interaction in nonleptonic weak decays is investigated. The investigation is based on U^∂_αL_α(x)U=∂_αL_α(x)+∫[L_4(x),H_(y,x_0)]d^3y, where L_α(L_α) means an operator in the interaction (Heisenberg) representation and U the unitary operator connecting these two representations. The strong interaction is assumed to be given as products of appropriate (V, A) currents. In the fundamen...

Structure of the Cell Walls of Micrococcus lysodeikticus. III. Isolation of a New Peptide Dimer, Nα-[L-Alanyl-γ-(α-D-glutamyl-glycine )]-L-lysyl-D-alanyl-Nα- [L-alanyl-γ-(α-D-glutamyl-glycine)]-L-lysyl-D-alanine

Ghuysen, Jean-Marie; Bricas, Evangelos; Lache, Marvin; Leyh-Bouille, Mélina (1968)
The pentapeptide monomer Nα-[L-aIanyl-γ-(α-D-glutamyl-glycine)]-L-lysyl-D-alanine and two isomeric peptide dimers have been quantitatively isolated from walls of Micrococcus lysodeikticus. In one of the peptide dimers, referred as to peptide dimer (Ala→Lys), two pentapeptide monomers are linked through Nє-(D-alanyl)-L-lysine linkages. This linkage is hydrolyzed by the Streptomyces ML endopeptidase but not by the Myxobacter AL I protease. In the second peptide dimer, referred as to peptide dim...

Measurement of Steady-State Growth Rates of a Thermophilic Alga Directly in Nature

Brock, Thomas D.; Brock, M. Louise (1968)
Steady-state growth rates of thermophilic algae can be determined directly in nature in the flowing waters of a hot spring channel by measuring the rate of loss of algal cells when the channel is darkened. The half time of the loss rate in the steady state is identical to the generation time. We studied the unicellular blue-green alga Synechococcus in Yellowstone National Park. Temperature and flow rate remained relatively constant throughout the experiment. Quantitative cores were taken and ...
