We have raised antisera against human prothrombin activation fragment F2 in rabbits and have chromatographed the respective immunoglobulin G fractions on prothrombin-Sepharose, Pr1-Sepharose, and F2-Sepharose immunoadsorbents. The specific antibody population obtained was utilized to construct a double antibody radioimmunoassay capable of measuring as little as 0.8 ng/ml of this component. Our ...

A presentation of a group with two generators having unsolvable word problem and an explicit countable presentation of Mihailova subgroup of F2 × F2 with finite number of generators are given. Where Mihailova subgroup of F2 × F2 enjoys the unsolvable subgroup membership problem. One then can use the presentation to create entities’ private keys in a public key cryptsystem.

A new Gray map between codes over F2 +uF2 +uF2 +uF2 + ....+ uF2 and codes over F2 is defined. It is proved that the Gray image of a linear (1− um)-cyclic code over F2 + uF2 + uF2 + uF2 + .... + uF2 of length n is a binary distance invariant quasi-cylic code of index 2m−1 and length 2mn. It is also proved that if n is odd, then every code of length 2mn over F2 which is the Gray image of a linear...

Ginsenoside F2 (F2), a protopanaxdiol type of saponin, was reported to inhibit human gastric cancer cells SGC7901. To better understand the molecular mechanisms of F2, an iTRAQ-based proteomics approach was applied to define protein expression profiles in SGC7901 cells in response to lower dose (20 μM) and shorter duration (12 hour) of F2 treatment, compared with previous study. 205 proteins we...

OBJECTIVE Several issues concerning F2 slope in dysarthria were addressed by obtaining speech acoustic measures and judgments of intelligibility for sentences produced in Habitual, Clear and Loud conditions by speakers with Parkinson's disease (PD) and healthy controls. PATIENTS AND METHODS Acoustic measures of average and maximum F2 slope for diphthongs, duration and intensity were obtained....

The PB1-F2 protein encoded by influenza A viruses can contribute to virulence, a feature that is dependent of its sequence polymorphism. Whereas PB1-F2 from some H1N1 viruses were shown to exacerbate the inflammatory response within the airways, the contribution of PB1-F2 to highly pathogenic avian influenza virus (HPAIV) virulence in mammals remains poorly described. Using a H5N1 HPAIV strain ...

Abstract: Phenomenological studies on the proton structure function F2 have been carried out to investigate the behavior of F2, i.e. its x andQ 2 dependence, in the transition from the deep-inelastic scattering region (Q 1GeV) to the photoproduction region (Q ≈ 0GeV). An overview of various results of F2 at low Q is given. To quantify the behavior of F2 at low Q , the drivatives d ln(F2)/d ln(x...

Let F2 be a free group of rank 2. We prove that there is an algorithm that decides whether or not, for given two elements u, v of F2, u and v are translation equivalent in F2, that is, whether or not u and v have the property that the cyclic length of φ(u) equals the cyclic length of φ(v) for every automorphism φ of F2. This gives an affirmative solution to problem F38a in the online version (h...
