BACKGROUND In a group of patients admitted for unstable angina, we investigated whether C-reactive protein (CRP) plasma levels remain elevated at discharge and whether persistent elevation is associated with recurrence of instability. METHODS AND RESULTS We measured plasma levels of CRP, serum amyloid A protein (SAA), fibrinogen, total cholesterol, and Helicobacter pylori and Chlamydia pneumo...

Polycyclic aromatic hydrocarbons (PAH) are widespread environmental contaminants, and some are potent carcinogens in rodents. Carcinogenic PAH are activated in cells to metabolites that react with DNA to form stable covalent DNA adducts. It has been proposed [Cavalieri, E. L. & Roger, E. G. (1995) Xenobiotica 25, 677-688] that unstable DNA adducts are also formed and that apurinic sites in the ...

Background: Unstable angina constitutes a clinical syndrome that is usually caused by atherosclerotic coronary artery disease and is associated with an increased risk of cardiac death and myocardial infarction. Material and methods: An open, prospective, observational, comparative study was conducted. The study included 50 cases in age group 20-80 years admitted in Government Medical College, A...

For a theory T in L, T is the theory of the models of T with an automorphism. If T is an unstable model complete theory without the independence property, then T has no model companion. If T is an unstable model complete theory and T has the amalgamation property, then T has no model companion. If T is model complete and has the fcp, then T has no model completion.

The in vitro instability of nitrate reductase (EC 1.6.6.1) activity from leaves of several species of higher plants was investigated. Decay of activity was exponential with time, suggesting that an enzyme-catalyzed reaction was involved. The rate of decay of nitrate reductase activity increased as leaf age increased in all species studied. Activity was relatively stable in certain genotypes of ...

The focusability of a long l)ulse XeCI excimer laser has been improved using confocal positive branch unstable resonators where the outcoupling is done through the convex mirror. For the outcoupler different reflectivity profiles are used. A near diffraction limited output beam is obtained from hard edge unstable resonators. A beam with only one central s1)ot in the focus of a lens can be obtai...

Least squares estimator of the stability parameter ̺ := |α|+ |β| for a spatial unilateral autoregressive process Xk,l = αXk−1,l +βXk,l−1 +εk,l is investigated and asymptotic normality with a scaling factor n5/4 is shown in the unstable case ̺ = 1. The result is in contrast to the unit root case of the AR(p) model Xk = α1Xk−1+ · · ·+αpXk−p+εk, where the limiting distribution of the least squares e...

unstable angina has progressive process and even in rest time, it happens frequently. it is a serious situation and 15-20 percent of patients are dying in duration of one year. treatment: patients often hospitalized because observation of their reactions to treatment is easier in hospital. treatment plan must be explain for them carefully. when patient’s situation due to anxiety is critical, be...
