| [the characteristics of a cholera outbreak in pushkino district, the azerbaijan ssr]. | the outbreak of cholera in the pushkino district of the azerbaijan ssr, caused by the penetration of vibrio cholerae into the water of the irrigation system, is described. altogether 2 cholera patients and 39 vibrio carriers were detected. the etiological agent of this infection was v. cholerae eltor, serovar ogawa, with typical phenotype characteristics. from all patients and 37 carriers virulent strains and from 2 carriers faintly virulent strains were isolated. in this outbreak family foci we ... | 1991 | 1831949 |
| limitations of balloon angioplasty for vein graft stenosis. | vein graft stenosis remains an important contributing factor to the failure of infrainguinal arterial reconstruction. repair of these lesions before graft occlusion provides sustained patency, yet the optimal method of repair has not been established. percutaneous transluminal balloon angioplasty of these vein graft lesions has been repeatedly advocated as an alternative to surgical revision. balloon angioplasty was used in 30 patients with 54 stenotic lesions occurring in autogenous vein grafts ... | 2007 | 1831863 |

| coincident recording and stimulation of single and multiple neuronal activity with one extracellular microelectrode. | this paper describes how an extracellular microelectrode may be used to stimulate neurons with brief, rectangular pulses and afterwards directly record the resultant activity. two obstacles are the stimulus artifact lingering in the electrical circuitry and transient tip potentials (ttps) arising from ion depletion at the electrode-tissue interface. electronic switching between the stimulus source and the recording amplifier eliminates direct stimulus artifact from the electrical circuitry, alth ... | 1991 | 1800855 |

| inbreeding in saguenay-lac-st-jean (quebec, canada): a study of catholic church dispensations 1842-1971. | saguenay-lac-st-jean (slsj) is a rather geographically isolated region of quebec which shows a high occurrence of hereditary disorders. it has been suggested that high inbreeding might explain this situation. we studied the inbreeding in the slsj region by 10-year periods from 1842 till 1971 using the catholic church dispensations. the values of the mean inbreeding coefficient were found to be low during the whole period, reaching a peak of 22.94 x 10(-4) during the period 1902-1911. the values ... | 2007 | 1797631 |
