Detection of E. coli in beach water within 1 hour using immunomagnetic separation and ATP bioluminescence
(John Wiley & Sons, Ltd., 2004-01)
The contamination of beach waters occurs from the discharge of storm water and sanitary sewer overflows containing faecal material. Additional faecal material derives from discharge of animals and waterfowl. In order to ...
Modeling and analyzing HIV transmission: the effect of contact patterns
(Elsevier, 1988-12)
A compartmental model is presented for the spread of HIV in a homosexual population divided into subgroups by degree of sexual activity. The model includes constant recruitment rates for the susceptibles in the subgroups. ...
Affinity binding of the cartilage proteoglycan protein-keratan sulfate core to immobilized hyaluronic acid
(Elsevier, 1978-10-01)
The protein-keratan sulfate core of bovine nasal cartilage proteoglycan was purified by affinity chromatography on a column of immobilized hyaluronic acid. The hyaluronic acid was immobilized by reaction with a hydrazido-alkyl ...
Bias reduction for risk ratio and vaccine effect estimators
(John Wiley & Sons, Ltd., 2001-06-15)
We examine the structural bias for established estimators of vaccine effects on susceptibility and for newer estimates of vaccine effects on infectiousness. We then propose and analyse new bias corrections for vaccine ...
Univariate and bivariate analyses of cholesterol and triglyceride levels in pedigrees
(Wiley Subscription Services, Inc., A Wiley Company, 1986-03)
A multivariate normal model for pedigree analysis is applied to fasting total serum cholesterol and total serum triglyceride measurements on 771 individuals in 95 pedigrees from Rochester, MN. Univariate and bivariate ...
Haplotype association analysis for late onset diseases using nuclear family data
(Wiley Subscription Services, Inc., A Wiley Company, 2006-04)
In haplotype-based association studies for late onset diseases, one attractive design is to use available unaffected spouses as controls (Valle et al. [1998] Diab. Care 21:949–958). Given cases and spouses only, the standard ...
Chloroquine accumulation and alterations of proteolysis and pinocytosis in the rat conceptus in vitro
(Elsevier, 1994-02-11)
The teratogenicity of chloroquine (CQ) has been hypothesized to result from its effects on lysosomal function, specifically the ability of the visceral yolk sac (VYS) to capture and degrade external macromolecules. Using ...
Room-temperature preparation and characterization of poly (ethylene glycol)-coated silica nanoparticles for biomedical applications
(Wiley Subscription Services, Inc., A Wiley Company, 2003-09-15)
Monodisperse, spherical, polyethylene glycol (PEG)–coated silica nanoparticles have been prepared at room temperature and characterized for the purpose of biomedical applications. The particles were synthesized by the ...
Localization of the human homolog of the yeast cell division control 27 gene (CDC27) proximal to ITGB3 on human chromosome 17q21.3
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1995-09)
The human homolog of the Saccharomyces cerevisiae cell division control 27 gene (CDC27) was mapped to human chromosome 17q12-q21 using a panel of human/rodent somatic cell hybrids and localized distal to the breast cancer ...
Detection of oxidative mutagens in an urban air-particulate extract: a preliminary study
(Elsevier, 1992-12)
The Ames assays strains TA98 and TA100 have been useful in characterizing complex mixtures from organic solvent extracts of particles from diesel-powered vehicles, ambient air, and other sources. In this paper we report ...
