Software facilitating numerical simulation of solid-state NMR experiments on polypeptides is presented. The Tcl-controlled SIMMOL program reads in atomic coordinates in the PDB format from which it generates typical or user-defined parameters for the chemical shift, J coupling, quadrupolar coupling, and dipolar coupling tensors. The output is a spin system file for numerical simulations, e.g., ...

In this study, we report the spin-lattice relaxation rate of hepatocellular carcinoma (HCC) and normal liver tissue in rats using a high-T(c) superconducting quantum interference device (SQUID) based nuclear magnetic resonance (NMR) spectrometer. The resonance spectrometer used for discriminating liver tumors in rats via the difference in longitudinal relaxation time in low magnetic fields was ...

SpinQ Triangulum is the second generation of desktop quantum computers designed and manufactured by Technology. SpinQ’s computer series, based on a room-temperature nuclear magnetic resonance (NMR) spectrometer, provides lightweight, cost-effective, maintenance-free computing platforms that aim to provide real-device experience for education kindergarten through 12th grade (K–12) college level....

case presentation we report a 5-year-old boy, who was presented with sudden right hand monoparesis and dysarthria. conclusions the patient was investigated with magnetic resonance angiography and diagnosed as md. introduction moyamoya disease (md) is a disorder caused by blocked arteries at the base of the brain. as the normal blood vessels narrow and become blocked, a person may suffer a strok...

ebstein anomaly is characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialization of the right ventricle and could be diagnosed in a routine transthoracic echocardiography exam. we reported a young man with right sided heart failure symptoms who was found to have biventricular failure with suspected apical displacement of septal leaflet of tr...

conclusion fs t2 w and ce fs t1 w sequences of axial planes were the most useful sequences in determination of active sacroiliitis. therefore, in patients with renal failure or allergy to contrast media, fs t2 wi can be obtained to detect active sacroiliitis. objectives the aim of this retrospective study was to assess the value of different magnetic resonance imaging (mri) sequences in evaluat...

conclusion adrenal iron in β-tm can be reliably measured in 3 tesla mri. the results highlight the absence of correlation between adrenal iron deposition both with serum ferritin and hepatic iron. results among patients, there was no significant correlation between plasma ferritin and adrenal t2*. significant difference was detected among t2* values of adrenals between the patient and control g...

introduction: the use of high-cost and high-tech magnetic resonance imaging (mri) has expanded over the past decade. a recently conducted research reported various causes with regard to their own country and healthcare system included aging population and advances in diagnostic technologies which could result in diagnostic services to become more applicable in clinical arena. increasing number ...
