to study the newly mentioned significance of the obstructive lesion morphology in coronary artery disease (cad), a study has been designed to compare this feature between patients having stable angina (sa) or unstable angina (ua) who underwent coronary angiography in tehran heart institute. study objectives were detection of the angina producing artery (ap a) and its morphologic lesion type, de...

Methylation of aspartic acid residues was first described in the literature in erythrocytes as a possible step of repairing aged membrane proteins [1]. During the process of aging, L-aspartyl residues are spontaneously converted to L-isoaspartyl via the unstable intermediate L-succinimide which undergoes a spontaneous hydrolysis, generating a mixture of normal L-aspartate (15-30%) and abnormal ...

Unstable hemoglobins (Hbs) are variants of adult Hbs that tend to precipitate and form insoluble inclusions (Heinz bodies) within the red blood cell (RBC) or RBC precursor. They induce a broad spectrum of manifestations from asymptomatic to severe hemolytic anemia and dyserythropoiesis. In case of severe hemolysis, treatment is not codified because of the rarity and diversity of molecular varia...

OBJECTIVE To assess prospectively the prognostic value of soluble cellular adhesion molecules (CAMs) in patients with unstable angina and non-Q wave myocardial infarction and to compare their prognostic accuracy with that of C reactive protein (CRP). DESIGN AND SETTING Prospective observational study of patients presenting acutely with unstable angina and non-Q wave myocardial infarction to a...

OBJECTIVES Based on previous observations on apolipoprotein(a), apo(a), in human unstable carotid plaques, we explored whether in the inflammatory environment of human atheroma, proteolytic events affect other hepatic and topically generated proteins in relation to the issue of plaque stability. METHODS AND RESULTS Forty unstable and 24 stable plaques from endarterectomy segments of affected ...

It has been shown that lipoprotein(a) (Lp[a]) may interfere with the fibrinolytic system and that the Lp(a) level in an individual remains constant. To evaluate the effects of Lp(a) on the fibrinolytic system in patients with unstable angina, we measured plasma levels of Lp(a), the alpha 2-plasmin inhibitor-plasmin complex, and the thrombin-antithrombin III complex. The latter is a marker of th...

BACKGROUND Identification of patients at risk for progression of coronary stenosis and adverse clinical events while awaiting coronary angioplasty is desirable. OBJECTIVE To determine the standard clinical or angiographic variables, or both, present at initial angiography associated with the development of adverse coronary events (unstable angina, myocardial infarction, and angiographic total...

In 1993, Henn, Lannes and Schwartz established a very strong relation between the Steenrod algebra and the category F.p/ of functors from the category E of finite dimensional Fp –vector spaces to the category E of all Fp –vector spaces, where Fp is the prime field with p elements [5]. To be more precise, they study the category U of unstable modules over the Steenrod algebra localized away from...

[1] We calculate growth rates for extraordinary mode Saturnian kilometric radiation generated by the electron cyclotron maser instability using a ring‐type (DGH) electron phase distribution model fitted to measured electron energy dist r ibut ions in Saturn’s auroral acceleration region. The observed distributions are unstable in spatially isolated regions of transverse linear size of order 10 ...
