A series of 16 synthetic scramblase candidates were prepared from a tris(aminoethyl)amine (TREN) scaffold and evaluated for ability to facilitate translocation of fluorescent phospholipid probes across vesicle membranes and endogenous phosphatidylserine across the plasma membrane of nucleated cells. More than half of the compounds were found to greatly accelerate phospholipid translocation in v...

BACKGROUND Little is known about risk factors associated with out-of-hospital outcomes in survivors of critical illness. We hypothesized that the presence of nucleated red blood cells in patients who survived critical care would be associated with adverse outcomes following hospital discharge. METHODS We performed a two-center observational cohort study of patients treated in medical and surg...

We describe an in vitro method which is useful for purging autologous bone marrow of neuroblastoma cells. The method utilizes a single murine monoclonal antibody 3G6 (an immunoglobulin M«)which we have previously developed against the ganglioside GD2;undiluted human complement; and unfractionated whole bone marrow at 1 x 107 nucleated cells/ml. Tumor cell clonogenic assays, Hoechst 33342 fluor...

Retraction of the blood clot by nucleated cells contributes both to hemostasis and to tissue remodeling. Although plasma fibronectin (FN) is a key component of the clot, its role in clot retraction is unclear. In this report, we demonstrate that the incorporation of FN into fibrin matrices significantly improves clot retraction by nucleated cells expressing the integrin a5b1. Further, we show t...

The study consisted of 18 dogs divided into Three groups. Each group consisted of Six dogs with elbow, hip and stifle joint disorders respectively. All the dogs were subjected to synovial fluid evaluation. The physico-chemical parameters recorded in these dogs included synovial fluid volume, color, viscosity, transparency, protein concentration, total nucleated cell count and differential cell ...

Acanthamoeba capping protein increased the rate of actin polymerization from monomers with and without calcium. In the absence of calcium, capping protein also increased the critical concentration for polymerization. Various models were evaluated for their ability to predict the effect of capping protein on kinetic curves for actin polymerization under conditions where the critical concentratio...

Fetal nucleated cells in the maternal circulation constitute a potential source of cells for the non-invasive prenatal diagnosis of fetal genetic abnormalities. We have investigated the use of the Magnetic Activated Cell Sorter (MACS) for enriching fetal nucleated erythrocytes. Mouse monoclonal antibodies specific for CD45 and CD32 were used to deplete leucocytes from maternal blood using MACS ...

We monitored the crystal growth kinetics of crystallization of a shear melted crystalline colloidal array (CCA). The fcc CCA heterogeneously nucleates at the flow cell wall surface. We examined the evolution of the (1 1 1) Bragg diffraction peak, and, for the first time, quantitatively monitored growth by measuring the temporal evolution of the Bragg diffraction interference fringes. Modeling o...

OBJECTIVE To identify criteria for the diagnosis of squamous cell carcinoma (SCC) and actinic keratosis (AK) by in vivo reflectance confocal microscopy (RCM). DESIGN Prospective RCM imaging of lesions suspected clinically and/or dermoscopically to be SCC or AK, followed by RCM assessment of the biopsy-proven SCCs and AKs. SETTING Private skin cancer clinic, Plantation, Florida. Patients A t...
