The murine situs inversus viscerum (iv) gene responsible for visceral asymmetry is linked tightly to the Igh-C cluster on chromosome 12
(Elsevier, 1990-07)
The iv gene controls left-right determination during murine organogenesis. To map this gene, we analyzed backcross progeny produced by mating (C57BL/6J x MEV/Ty)F1-iv/+ heterozygotes to C57BL/6J-iv homozygotes. Hybridization ...
Evidence for pteridine regulation of lead-mediated inhibition of uroporphyrinogen and heme formation in rat bone marrow
(Elsevier, 1992-03)
Uroporphyrin I (URO I) accumulation has been reported in the bone marrow of rats exposed to lead, suggesting a sensitivity of uroporphyrinogen III cosynthase (COSYN) to this heavy metal. Furthermore, it has been reported ...
Determination of aerosol strong acidity losses due to interactions of collected particles: Results from laboratory and field studies
(Elsevier, 1992-04)
Existing methods of measuring atmospheric aerosol strong acidity adequately prevent neutralization of fine-particle acidity by removing course alkaline particles and gaseous ammonia from air samples. However, these techniques ...
Self-reported physical health among the aged in Wuhan, China
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-07)
It has long been recognized that cross-cultural differences in health and illness reflect not only genuine variation in the incidence and prevalence of morbidity, disability, and mortality, but also the social processes ...
Pili (fimbriae) of Branhamella species
(Elsevier, 1990-05-14)
: Pili (fimbriae) have frequently been found to be involved in the attachment of bacteria to mucosal epithelial cells, an important initial step in the disease process. The purpose of this study was to determine if Branhamella ...
Spinocerebellar ataxia type 1 with multiple system degeneration and glial cytoplasmic inclusions
(Wiley Subscription Services, Inc., A Wiley Company, 1996-02)
Spinocerebellar ataxia type 1 (SCA1) is a dominantly inherited progressive neurological disorder characterized by neuronal degeneration and reactive gliosis in the cerebellum, brainstem, spinocerebellar tracts, and dorsal ...
Chlorpyrifos: Assessment of Potential for Delayed Neurotoxicity by Repeated Dosing in Adult Hens with Monitoring of Brain Acetylcholinesterase, Brain and Lymphocyte Neurotoxic Esterase, and Plasma Butyrylcholinesterase Activities
(Elsevier, 1993-07)
Chlorpyrifos: Assessment of Potential for Delayed Neurotoxicity by Repeated Dosing in Adult Hens with Monitoring of Brain Acetylcholinesterase, Brain and Lymphocyte Neurotoxic Esterase, and Plasma Butyrylcholinesterase ...
Fluorometric analysis of endocytosis and lysosomal proteolysis in the rat visceral yolk sac during whole embryo culture
(Wiley Subscription Services, Inc., A Wiley Company, 1997-09)
Using spectrofluorimetry and fluorescence microscopy, we analyzed the uptake and degradation of fluorescein isothiocyanate-conjugated bovine serum albumin (FITC-albumin) by the rat visceral yolk sac (VYS) during whole ...
Characteristics of individuals and long term reproducibility of dietary reports: The Tecumseh diet methodology study
(Elsevier, 1990)
Food frequency reports in 1967-1969 were compared to frequency reports of the same foods asked retrospectively in 1982-1983 about 1967-1969 for 1184 respondents aged 45-64 years in the Tecumseh Community Health Study. The ...
Airborne emissions at skin surfaces: a potential biological exposure index
(Springer-Verlag, 1996-05)
Dermal exposures of methanol were administered in a clinical study designed to compare several biological indicators. Four subjects were exposed in five exposure sessions of varying length. In each session, a sequence of ...
