| acute health effects from community exposure to n-propyl mercaptan from an ethoprop (mocap)-treated potato field in siskiyou county, california. | a 145-acre potato field adjacent to dorris, california, was treated with ethoprop (mocap) to control nematodes. ethoprop releases n-propyl mercaptan, a highly odorous and volatile gas, as a degradation product of the pesticide. an epidemiological investigation was undertaken by the california department of health services because community residents sought medical attention for odor-related illness. elevated health effects were found among those who reported smelling a strong odor (n-propyl merc ... | 1991 | 2069429 |
| arboviral infections in the united states. | arboviruses are important considerations in the differential diagnosis of encephalitis and other acute infections. alterations in the environment and in human behaviors contribute to changing patterns of arboviral transmission. these trends, the periodic epidemic resurgence of arboviral diseases such as st. louis encephalitis, and the discovery of new arboviruses present a continued challenge to infectious disease clinicians. | 1991 | 1646839 |
| determinants of genital human papillomavirus infection in young women. | carcinoma of the cervix has several well-established epidemiologic risk factors, including multiple sexual partners and early age at first intercourse. human papillomavirus (hpv) infection appears to have an etiologic role in the development of cervical neoplasia, but evidence linking hpv infection to known risk factors for cervical cancer has been inconsistent. the lack of expected correlations may be due to the inaccuracy of hpv assays previously used. a polymerase chain reaction dna amplifica ... | 1991 | 1649312 |
| high fecundity of amenorrhoeic women in embryo-transfer programmes. | there is uncertainty over whether the steady decline in human fertility with increasing maternal age is due to quality of the oocyte or of the endometrium. to clarify the issue age-related implantation and pregnancy rates in two embryo-transfer programmes were examined in relation to embryo quality and type of menstrual cycle. in both the uk and the us programmes rates were higher in previously amenorrhoeic (acyclic) women than in eugonadal women, irrespective of age and number of embryos replac ... | 1991 | 1677120 |
