c-reactive protein (crp) response was studied in 44 patients with acute angina pectoris admitted to the coronary care unit. 71 % of patients with acute myocardial infarction (mi)had positive crp test while 73% of patients presumed to have unstable angina pectoris had negative crp test. this test can be helpful in differentiating between acute mi and unstable angina pectoris.

we consider the semilinear elliptic boundary value problem  = ∈∂ω− δ = ∈ωu x xu x f u x x( ) 0;( ) λ ( ( ));where λ > 0 is a parameter, ω is a bounded region in rn with a smooth boundary, and f is asmooth function. we prove, under some additional conditions, the existence of a positive solution for λlarge. we prove that our solution u for λ large is such that = →∞∈ω|| u ||: sup| u(x) |xas λ ...

The long-time behavior of the survival probability for unstable multilevel systems that follows the power-decay law is studied based on the N-level Friedrichs model, and is shown to depend on the initial population in unstable states. A special initial state maximizing the asymptote of the survival probability at long times is found and examined by considering the spontaneous emission process f...

introduction: unstable angina as a clinical condition includes a major group of patients manifested with acute coronary syndrome. misdiagnosis of this clinical syndrome causes myocardial infarction (mi) and death. conventional and advanced forms of treatment are used with the aim of rapid stabilization of unstable angina. although infusion of glucose - insulin - potassium (gik) solution has had...

this paper presents a simplified approach to estimate the resultant force, which should be provided by a retention system, for the equilibrium of unstable slopes. the results were obtained with a developed algorithm, based on limit equilibrium analyses, that assumes a two-part wedge failure mechanism. design charts to obtain equivalent earth pressure coefficients are presented. based on the res...

OBJECTIVE/BACKGROUND The aim was to investigate the expression of genes associated with carotid plaque instability and their protein products at a local and systemic level. METHODS Carotid plaques from 24 patients undergoing carotid endarterectomy (CEA) were classified as stable or unstable using clinical, histological, ultrasound, and transcranial Doppler criteria, and compared using whole g...

We demonstrate that AdS5 × T pq is unstable, in the sense of Breitenlohner and Freedman, for unequal p and q. This settles, negatively, the long-standing question of whether the T pq manifolds for unequal p and q might correspond to non-supersymmetric fixed points of the renormalization group. We also show that the AdS3×S vacuum of Sugimoto’s USp(32) open string theory is unstable. This explain...

We study decay of unstable D-branes in string theory in the presence of electric field, and show that the classical open string theory results for various properties of the final state agree with the properties of closed string states into which the system is expected to decay. This suggests a duality between tree level open string theory on unstable D-branes and closed strings at high density.

conclusions: patent coronaries of ua/nstemi patients have a trend to higher tfcs compared to normal values. presence of significant coronary lesions in these patients significantly increases tfc. objectives: the present study is aimed to measure the tfc in the coronary arteries of ua/nstemi patients to find abnormalities in diseased or patent vessels and compare with the normal values. patients...
