The endothelium may contribute to fibrinolysis through the binding of plasminogen activators or plasminogen activator inhibitors to the cell surface. Using a solid-phase radioimmunoassay, we observed that antibodies to recombinant tissue-type plasminogen activator (rt-PA) and plasminogen activator inhibitor type 1 (PAI-1) bound to the surface of cultured(More)
The urokinase receptor (uPAR) is linked to plasma membranes through a glycosylphosphatidylinositol (GPI) anchor. It has been posited that the GPI anchor facilitates clearance of uPAR-bound complexes between two chain urokinase (tcuPA) and plasminogen activator inhibitor type 1 (PAI-1) by the alpha 2-macroglobulin receptor (alpha 2MR) which permits(More)
BACKGROUND The increasing scope of health supervision recommendations challenges well-child care delivery in the United States. Comparison of the United States with other countries' delivery systems may highlight different assumptions as well as structural approaches for consideration. OBJECTIVE Our goal was to describe the process of well-child care(More)
Urokinase-type plasminogen activator (uPA) participates in diverse (patho)physiological processes through intracellular signaling events that affect cell adhesion, migration, and proliferation, although the mechanisms by which these occur are only partially understood. Here we report that upon cell binding and internalization, single-chain uPA (scuPA)(More)
Epidemiologists have shown how birth outcomes are generally robust for immigrant Latina mothers, despite often situated in poor households, advanced by their strong prenatal and nutritional practices. But little is known about (1) how these protective factors may differ among Latino subgroups, (2) the extent to which birth outcomes, ongoing maternal(More)
We performed a retrospective cohort study in a largely Latino population in Los Angeles, surveying 95 parents of 11-17 year old girls between May and June 2008 to examine factors associated with [1] parental consent for Human Papillomavirus (HPV) immunization one year after vaccine implementation and [2] parental support of an HPV vaccine mandate for(More)
OBJECTIVE The purpose of this study was to investigate the predictors and frequency of book-sharing activities in a nationally representative sample of families with young children and to examine the extent to which parents report that pediatric health care providers are addressing early literacy activities. METHODS This study analyzed data from the 2000(More)
Urokinase-type plasminogen activator (uPA) induces cell adhesion and chemotactic movement. uPA signaling requires its binding to uPA receptor (uPAR/CD87), but how glycosylphosphatidylinositol-anchored uPAR mediates signaling is unclear. uPAR is a ligand for several integrins (e.g. alpha 5 beta 1) and supports cell-cell interaction by binding to integrins on(More)
OBJECTIVE The aims of this study are to describe growth trajectories in the body mass index (BMI) among the major racial and ethnic groups of US children and to identify predictors of children's BMI trajectories. METHODS The Early Childhood Longitudinal Study-Birth Cohort (ECLS-B) was used to identify predictors of BMI growth trajectories, including child(More)
Human umbilical vein endothelial cells in culture (HUVEC) express receptors for urokinase-type plasminogen activators (u-PA). The immunochemical nature of this receptor and its relationship to u-PA receptors expressed by other cell types is unknown. Cross-linking active site-blocked u-PA to HUVEC lead to an increase in its apparent molecular mass by(More)
