1. The concentration in plasma of fibrinogen derivatives fibrinopeptide A (FPA) and B beta 1-42 and the platelet release products beta-thromboglobulin (beta TG) and platelet factor 4 (PF4) have been determined in patients with acute and chronic liver disease. 2. In 21 patients with fulmiant hepatic failure on admission in grade III or IV coma the plasma FPA, B beta 1-42, beta TG and PF4 levels ...

The effect of the amino acid analog FPA on vaccinia virus replication in HeLa cells was investigated, By varying the dose of FPA or the time after infection at which the analog was added to cultures, it was possible to inhibit differentially the synthesis of viral components in vaccinia-infected cells. When suflicient FPA was added t,o GUItures at the t,ime of infection, the synthesis of viral ...

This paper describes the application of multiple IR projector technologies to Hardware-in-the-Loop (HWIL) simulations at the US Army Aviation and Missile Command's (AMCOM) Missile Research, Development, and Engineering Center (MRDEC). Several projectors utilizing a variety of emerging technologies are currently being successfully applied within the HWIL facilities of AMCOM’s MRDEC. Projector te...

p-Fluorophenylalanine (FPA) derepresses beta-galactosidase synthesis at 35 C but not at 25 C in Escherichia coli K-12, strain MC132 (lac I1,2), a strain with a temperature-sensitive lac repressor. In contrast, strain MC130 (lac I(+)) is not derepressed by FPA at 35 C. Temperature-shift experiments with strain MC132 in the presence of FPA and other reagents (isopropyl-1-thio-beta-d-galactoside o...

A requirement for software productivity analysis and estimation is the ability to measure the size of a software product from the user’s viewpoint, that is, from a functional perspective rather than from a technical perspective. One example of such a measurement method is Function Point Analysis (FPA). FPA is now widely used in the Management Information Systems (MIS) domain, where it has becom...

This study was designed to determine whether venous thrombosis is associated with a characteristic pattern in the plasma concentrations of fibrinopeptides and platelet alpha granule proteins. Patients undergoing elective craniotomy for tumor or vascular abnormality were studied prospectively for venous thrombosis with the 1251-fibrinogen uptake test and with daily measurement of the plasma conc...

This work presents an open implementation of the Fundamental Parameters Approach (FPA) models for analysis of X-ray powder diffraction line profiles. The original literature describing these models was examined and code was developed to allow for their use within a Python based least squares refinement algorithm. The NIST interest in the FPA method is specific to its ability to account for the ...

Fibrinopeptide A (FPA) is a very sensitive marker of fibrin generation in vivo. Because an imbalance between thrombogenic and thrombolytic forces may be responsible for the failure to recanalize and for reocclusion of coronary arteries, such a marker could be of eminent value during thrombolytic treatment of acute myocardial infarction. Thirty-four consecutive patients with acute myocardial inf...

As staring focal plane array (FPA) detectors continue to mature, FPA based IR imaging systems are available in more compact packages that are lighter and consume less power than first or second generation scanning IR sensor packages. However, standard IR analysis models indicate that staring FPA based cameras, while having excellent sensitivity, will have reduced resolution when compared to sca...

A need for active adjustment of a focal plane array (FPA) exists for space based telescopes at Sandia National Laboratories. Legacy systems relied upon manual alignment of the FPA to the optics train. The alignment was done by checking the image then adjusting the position of the FPA with shims, repeated until the desired alignment and focus were achieved. This approach has several drawbacks, i...
