Melanoma diagnosis depends on the experience of doctors. Symmetry is one of the most important factors to measure, since asymmetry shows an uncontrolled growth of cells, leading to melanoma cancer. A system for melanoma detection in diagnosing melanocytic diseases with high sensitivity is proposed here. Two different sets of features are extracted based on the importance of the ABCD rule and sy...

OBJECTIVE To compare the reliability of a new 7-point checklist based on simplified epiluminescence microscopy (ELM) pattern analysis with the ABCD rule of dermatoscopy and standard pattern analysis for the diagnosis of clinically doubtful melanocytic skin lesions. DESIGN In a blind study, ELM images of 342 histologically proven melanocytic skin lesions were evaluated for the presence of 7 st...

We have demonstrated efficiency of employing the ABCD matrix approach to transform higher-order structured Laguerre–Gaussian (sLG) beams into structurally stable astigmatic sLG (asLG) beams, highlighting their dynamics at propagating. Radical transformations beam structure by a cylindrical lens form not only orbital angular momentum (OAM) fast oscillations and bursts, but also make asLG unstabl...

Patients with transient ischemic attacks (TIAs) are a heterogeneous group in terms of risk factors, symptomatology, underlying disorders, and prognosis.1 The importance of recognizing this common condition lies in the high risk of early stroke that TIAs carry (3.1% at 2 days, 5.2% at 7 days, 8.0% at 30 days, and 9.2% at 90 days).2,3 Recent eviden...

BACKGROUND AND PURPOSE Predictive instruments based on clinical features for early stroke risk after transient ischemic attack suffer from limited specificity. We sought to combine imaging and clinical features to improve predictions for 7-day stroke risk after transient ischemic attack. METHODS We studied 601 consecutive patients with transient ischemic attack who had MRI within 24 hours of ...

Background and Purpose—Transient ischemic attack (TIA) etiologic data and the ABCD score may improve early stroke risk prediction, but studies are required in population-based cohorts. We investigated the external validity of the ABCD score, carotid stenosis, and atrial fibrillation for prediction of early recurrent stroke after TIA. Methods—Patients with TIA in the North Dublin city population...

We characterize the product line choice and pricing of a monopolist as the upper envelope of net marginal revenue curves to the individual product demand functions. The equilibrium product varieties to include in a product line are those yielding the highest upper envelope. In a central case (corresponding to a generalized vertical differentiation framework), the equilibrium range of...

Amphotericin B deoxycholate (AmB) or Amphotericin B colloidal dispersion (ABCD) are used in clinics for the treatment of systemic fungal infections. The goal of our study was to compare the nephrotoxicity of these drugs in rat kidney. The effects of AmB and ABCD on the ultrastructure of the epithelium of renal tubules were studied and evaluated using morphometric and statistical methods. Two gr...
