background coronary artery anomalies are not common, but could be very serious. objectives this study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (mdct). patients and methods the results of cardiac mdct study in 2697 consecutive patients were analyzed retrospectively. acquisition was performed by a 64-detector row ct machine. imag...

It is argued that the gauge anomalies are only the artefacts of quantum field theory when certain subtleties are not taken into account. With the Berry's phase needed to satisfy certain boundary conditions of the generating path integral, the gauge anomalies associated with homotopically nontrivial gauge transformations are shown explicitly to be eliminated, without any extra quantum fields int...

purpose: to assess the frequency and type of associated malformations and chromosomal anomalies among patients with anophthalmia, microphthalmia, and coloboma in sistan and baluchestan province. methods: patients with a clinical diagnosis of anophthalmia, microphthalmia, or coloboma were examined to find any anomaly in craniofacial, muscle-skeletal, cardiac, neurologic and urogenital systems. a...

Abstract Background Tetralogy of Fallot is the most common congenital cyanotic heart disease. Advances in surgical repair recently facilitate survival affected patients into adulthood with good quality life. Despite imaging plays crucial role diagnosis TOF patients, no single diagnostic modality suffices for complete evaluation TOF. Thus, different tools should be used alone or combination acco...

The anomaly cancellation condition of the Standard Model may be unnatural in theories with extra dimensions as an anomaly of a low-energy 4-dimensional theory can be canceled by an inflow from a bulk. This inflow may give rise to an observable effect at low energies. We analyze several physical models in which this effect exists and estimate constraints on its value, imposed by the modern exper...

We give an overview of the issue of anomalies in field theories with extra dimensions. We start by reviewing in a pedagogical way the computation of the standard perturbative gauge and gravitational anomalies on non-compact spaces, using Fujikawa’s approach and functional integral methods, and discuss the available mechanisms for their cancellation. We then generalize these analyses to the case...

Theories with large extra dimensions can generate small neutrino masses when the standard model neutrinos are coupled to singlet fermions propagating in higher dimensions. The couplings can also generate mass splittings and mixings among the flavour neutrinos in the brane. We systematically study the minimal scenario involving only one singlet bulk fermion coupling weakly to the flavour neutrin...

OBJECTIVE: We aimed to determine if multidetector-row computed tomography angiography is an effective and non-invasive method for diagnosing anomalous pulmonary venous drainage. MATERIALS AND METHODS: We performed a retrospective review of 2905 cases from July 2003 to November 2007 in which cardiac multidetector-row computed tomography was used. Of the cases, 393 evaluated congenital cardiopath...

Considerable numbers of congenital cardiac anomalies are missed at the time of delivery. Study reports show that congenital cardiac anomalies are the second most common birth defect in many countries. Despite this fact, our previous study showed that the prevalence of congenital cardiac anomalies is the fifth most common one, indicating that many of these defects might not be properly diagnosed...
