The Superior Thyroid Artery (STA) is the dominant arterial supply of the thyroid gland, larynx and the neck. Awareness of variations in STA is crucial for invasive operations in the neck region. We reported a case that STA derives from the Common Carotid Artery (CCA). A patient with possible transient ischemic attack had an digital substraction angiography. Angiography revealed superior thyroid...

The compression of the proximal part of the celiac trunk by median arcuate ligament of the diaphragm during expiration is defined as median arcuate ligament syndrome. It is a rare cause of chronic mesenteric ischemia. We report two cases with this syndrome, primarily diagnosed by Doppler ultrasound. The diagnosis was confirmed with digital substraction and computed tomography angiography in bot...

thirty one patients with biologic and clinical diagnosis of hyperparathyroidism were submitted to thalium-technetium scan prior to exploration of the neck. scan findings were compared with the pathologic results. surgical exploration of the neck showed a parathyroid adenoma in 24 patients, parathyroid carcinoma in one patient, normal parathyroid in another patient and parathyroid hyperplasia in...

We provide new formulas for the energy of black hole solutions in anti-de Sitter (AdS) sector a generic gravity theory with curvature-squared terms. This is achieved by addition counterterms extrinsic type (\emph{Kounterterms}) which produces finite variation total action. The procedure compatible boundary conditions asymptotically AdS spaces within framework Quadratic Curvature Gravity (QCG) t...

Título: Independencia entre operaciones aritméticas básicas: evidencia desde la neuropsicología cognitiva. Resumen: Los casos descritos en la literatura ponen de manifiesto que las operaciones aritméticas pueden funcionar independientemente, lo que permite inferir que los procesos cognitivos implicados en las distintas operaciones podrían ser distintos. El objetivo de este trabajo es determinar...

To the editor, most anesthesiologists estimate blood loss by rough visual assessment, by noting its effects on cardiovascular parameters, by weighing of swabs, by substraction of fluids used in surgical irrigation from blood in suction reservoir, either by laboratory estimation or by trusting their experiences and instinct. I describe here a simple and practical method of estimating operative b...

ÐHighly-accurate solutions for the lid-driven cavity ̄ow are computed by a Chebyshev collocation method. Accuracy of the solution is achieved by using a substraction method of the leading terms of the asymptotic expansion of the solution of the Navier±Stokes equations in the vicinity of the corners, where the velocity is discontinuous. Critical comparison with former numerical experiments con®r...

All-sky maps of the cosmic microwave background temperature fluctuations are usually represented by a spherical harmonic decomposition involving modes labelled by their degree l and order m (where −l 6 m 6 +l). The zonal modes (i.e those with m = 0) are of particular interest because they vary only with galactic latitude; any anomalous behaviour in them might therefore be an indication of erron...

Ratios of azimuthal angle correlations between two jets produced at large rapidity separation are studied in the N = 4 maximally supersymmetric Yang-Mills (MSYM) theory. It is shown that these observables, which directly prove the SL(2,C) symmetry present in gauge theories in the Regge limit, exhibit an excellent perturbative convergence. They are compared to those calculated in QCD for differe...
