| developmental changes in mitochondria during the transition into lactation in the mouse mammary gland. ii. membrane marker enzymes and membrane ultrastructure. | the activity of cytochrome oxidase (an inner mitochondrial membrane marker) in mouse mammary gland homogenates was found to increase five- to sixfold from late pregnancy to day 8 of lactation, while that of monoamine oxidase (an outer membrane marker) increased only about 25%. the specific activity of cytochrome oxidase in the isolated mitochondria decreased slightly over the same period while the specific activity of monoamine oxidase decreased fivefold. this reflects the fact that both cytochr ... | 1976 | 178667 |
| demonstration of agglutinating antibodies against vibrio parahaemolyticus in the yellow tail flounder (limanda ferruginea). | sera from the salt water fish (yellow tail flounder) and the fresh water fish (rainbow trout) were tested for the presence of circulating antibodies against nine strains of vibrio parahaemolyticus and one of v. alginolyticus. thirteen out of 26 flounder sera tested gave agglutinating reactions against one specific strain of v. parahaemolyticus; strain no. 3525. seven rainbow trout sera tested failed to agglutinate any of the strains tested. all agglutinating activity was lost upon boiling the an ... | 1976 | 931748 |
| butandioldehydrogenase in vibrio parahaemolyticus. | 396 strains of v. parahaemolyticus, 345 originating from togo and 51 from japan, were submitted to the study of butandiol dehydrogenase (bdh). it was found that 52.3% of the strains were bdh-positive and 44.2% bdh-negative. an intermediate group characterized by weak reactions amounted to 3.5% of the strains. the distribution of this enzyme parallels to a certain degree the results of serotyping. positive reactions have been found in all or most strains belonging to serotypes 03k29, o4k8, 04k12, ... | 1976 | 934022 |
| relationships between heat resistance and phospholipid fatty acid composition of vibrio parahaemolyticus. | vibrio parahaemolyticus was grown in tryptic soy broth (tsb) containing nacl levels of 0.5, 3.0, and 7.5% (wt/vol). cultures incubated at 21, 29, and 37 c were harvested in late exponential phases and thermal death times at 47 c (d47 c; time at 47 c required to reduce the viable population by 90%) were determined in phosphate buffer containing 0.5, 3.0, and 7.5% nacl. at a given nacl concentration in the growth medium, d47 c values increased with elevated incubation temperatures and with elevate ... | 1976 | 938034 |
| inactivation of the biological activities of the thermostable direct hemolysin of vibrio parahaemolyticus by ganglioside gt1. | biological activities of the thermostable direct hemolysin produced by vibrio parahaemolyticus, such as its hemolytic activity and lethal activity, were inhibited by neuraminidase-sensitive gangliosides, of which gt1 ganglioside was the most inhibitory. neuraminidase-resistant gangliosides did not affect the activities of the hemolysin. results showed that horse erythrocytes, which are resistant to the hemolysin, do not contain the neuraminidase-sensitive gangliosides gt1 and gd1a. therefore, we ... | 1976 | 947841 |
| [the dehydrogenation of butandiol by "vibrio parahaemolyticus" and other vibrios (author's transl)]. | the butandiol dehydrogenase was examined in 64 vibrios isolated in togo 1970/71. this enzyme was found in all of the not halophilic strains and in the species vibrio alginolyticus, whereas the species v. parahaemolyticus exhibited as well dehydrating as not dehydrating strains. the butandiol dehydrogenase could be a good marker for epidemiologic analysis in characterizing v. parahaemolyticus strains isolated from different sources, especially if no antisera are available. | 1976 | 952445 |

| an autoradiographic study of the sensory innervation of teeth. ii. dental pulp and periodontium. | autoradiography of axoplasmically transported proteins revealed that both dental pulp and periodontium receive sensory innervation from the trigeminal ganglion in the form of plexuses and free and organized sensory receptors, including apparent corpuscular ones. corpuscular receptors in the pulp suggest this tissue may be responsive to modalities other than pain. | 1977 | 269163 |
| in vitro enamel demineralization by streptococcus mutans in the presence of salivary pellicles. | salivary pellicles developed on extracted teeth favorably affected the degree and nature of enamel demineralization when the teeth were incubated in vitro with either of two pure strains of cariogenic streptococcus mutans. the mechanism responsible for this protection may relate to the permselective properties of these salivary pellicles. | 1977 | 270509 |

| calcium gradient dependent pyrophosphate formation by sarcoplasmic vesicles. | the vesicles of the sarcoplasmic membranes synthesize pyrophosphate from inorganic phosphate. pyrophosphate synthesis proceeds as long as a calcium gradient is maintained across the vesicular membranes. pyrophosphate synthesis is inhibited by low concentrations of nucleoside triphosphates. | 1977 | 203132 |
| structure of human hemoglobin messenger rna and its relation to hemoglobinopathies. | 1. one-fifth to 1/4 of globin mrna is untranslated sequence other than polyadenylic acid. 2. the untranslated sequences of mrna vary markedly in their sequence and in their length. 3. globin mrnas demonstrate a marked bias in codon selection. 4. viral mrna shows a quite different pattern of codon selection; therefore, the selection of codons is not uniform for all mrnas functioning in animal cells. 5. elongated hemoglobin chains can be accounted for by frame-shift mutations, or point mutations w ... | 1977 | 205979 |

| effect of zinc ion on the hemolytic activity of thermostable direct hemolysin from vibrio parahaemolyticus, streptolysin o, and triton x-100. | the effect of zn2+ on hemolysis induced by the thermostable direct hemolysin from vibrio parahaemolyticus (vibriolysin) streptolysin o, and triton x-100 was studied. we found that in certain buffers, such as tris(hydroxymethyl)-aminomethane-hydrochloride, boric acid-borax, and n-hydroxyethyl piperazine-n'-2-ethanesulfonic acid-sodium hydroxide, hemoglobins released from erythrocytes were easily precipitated by addition of zn2+, thus resulting in a false inhibition of hemolysin by zn2+ when hemol ... | 1977 | 330401 |
