surgical aortic valvuloplasty using the cavitron ultrasonic surgical aspirator: an invasive hemodynamic follow-up study.	valve repair and calcium debridement in patients with calcific aortic stenosis, using the cavitron ultrasonic surgical aspirator (cusa), results in a reduction in the aortic valve gradient while potentially avoiding long-term problems inherent to prosthetic valves. invasive followup data in these patients has not previously been reported. ten patients in whom cusa debridement was performed underwent cardiac catheterization prior to and 8.0 +/- 2.5 months following the procedure. compared to base ...	2007	1913786
formycin a resistant mutants due to defect in adenosine transport system in vibrio parahaemolyticus.	an antibiotic formycin a inhibited growth of vibrio parahaemolyticus under certain conditions, which suggested that formycin a was taken up by cells under these conditions. we found that formycin a was transported via the adenosine transport system which we previously reported as a na(+)-coupled cotransport system. we isolated many formycin a resistant mutants, and about half of them grew very poorly on adenosine as a sole source of carbon. judging from their reversion frequencies, these mutants ...	1991	1914010
occurrence of 2-keto-3-deoxy-d-manno-octonic acid in lipopolysaccharides isolated from vibrio parahaemolyticus.	the occurrence of 2-keto-3-deoxy-d-manno-octonic acid (kdo) in lipopolysaccharides (lps) of vibrio parahaemolyticus was demonstrated for the first time by gas chromatography-mass spectrometry after dephosphorylation, reduction, and methylation. kdo was virtually completely phosphorylated, since no kdo was detected by either gas chromatography or thiobarbituric acid assay before dephosphorylation. the level of kdo in all six strains of v. parahaemolyticus investigated ranged from 0.37 to 0.69%, w ...	1991	1917863
optical sectioning of microbial biofilms.	scanning confocal laser microscopy (sclm) was used to visualize fully hydrated microbial biofilms. the improved rejection of out-of-focus haze and the increased resolution of sclm made it preferable to conventional phase microscopy for the analysis of living biofilms. the extent of image improvement was dependent on the characteristics of individual biofilms and was most apparent when films were dispersed in three dimensions, when they were thick, and when they contained a high number of cells. ...	1991	1917879
renal damage in mice after sequential cisplatin and irradiation: the influence of prior irradiation on platinum elimination.	doses of 4-6 mg kg-1 c-ddp given 6 months before renal irradiation caused only a modest increase in functional radiation damage (def 1.1). these effects could be explained by additive toxicities and the damage was much less than when c-ddp was given 3-6 months after irradiation. pharmacokinetic studies did not demonstrate any decrease in the rate of platinum elimination after previous low-dose renal irradiation.	2007	1924867
tryptophan 65 is essential for hemolytic activity of the thermostable direct hemolysin from vibrio parahaemolyticus.	the effect of modification of aromatic and ionizable amino acid residues on the hemolytic activity of a thermostable direct hemolysin from vibrio parahaemolyticus was examined. tryptophan 65, one of the two tryptophan residues per subunit, was specifically modified with n-bromosuccinimide, resulting in complete loss of hemolytic activity. however, neither nitration with tetranitromethane of one of the nine tyrosine residues nor nlm-ethoxyformylation of two of the four histidine residues caused a ...	1991	1926183
[age determination of venous thrombi by ultrasound].	in addition to diagnosing deep-vein thrombosis of the lower limb and pelvis, determination of the age of the thrombus is of considerable importance in guiding treatment. the present study was done to find out whether thrombus age can be determined by ultrasound morphology. 138 examinations were carried out on 76 lower limbs with phlebographically demonstrated thrombosed veins. diameter of the thrombosed vein, echogenicity of the thrombus and demarcation of the venous wall from its surroundings w ...	2007	1932731
acute amphetamine-induced subsensitivity of a10 dopamine autoreceptors in vitro.	extracellular recordings were obtained from spontaneously active, presumed dopamine (da) neurons of the ventral tegmental area (vta) of the rat in a slice preparation. bath-applied (+)-amphetamine (amph) (1-30 microm) induced a concentration-dependent decrease in the firing rate of these neurons, which tended to saturate with the highest concentrations used (n = 11). this inhibitory effect was dependent on the activation of d2 receptors since it was reversed by the d2 antagonist sulpiride (n = 8 ...	1991	1933376
measurement of sensitivity to adriamycin in hybrid spheroids.	using the newly developed hybrid spheroid system, we have been able to measure sensitivities to adriamycin in two sublines of lovo cells (a human colon adenocarcinoma line). hybrid spheroids are composed of coagglomerated lovo cells, and nonproliferating hela "feeder" cells, mimicking a population of minitumors. spheroids of uniform size, but containing different numbers of lovo cells, were incubated with various concentrations of adriamycin and after washing, plated for colony formation. binomi ...	1991	1933483
