ADAPT-NMR (Assignment-directed Data collection Algorithm utilizing a Probabilistic Toolkit in NMR) represents a groundbreaking prototype for automated protein structure determination by nuclear magnetic resonance (NMR) spectroscopy. With a [(13)C,(15)N]-labeled protein sample loaded into the NMR spectrometer, ADAPT-NMR delivers complete backbone resonance assignments and secondary structure in ...

The effects of chemotherapy on living tumor tissue in hamsters and rats were investigated by measuring the 31P nuclear mag netic resonance spectra using topical magnetic resonance. Hu man neuroblastoma, human glioblastoma, and rat glioma tumor cells were inoculated s.c. in the lumbar region of the animals. After the diameter of the tumors increased to 1.5 cm, in vivo 31P nuclear magnetic resona...

we present a case report of bupropion-induced diplopia in a 26-year-old woman who suffered from atypical depression. âfter four weeks of taking bupropion (225 mg per day) she complained of headaches, blurred vision, and diplopia. no neurological and ophthalmologic abnormal signs were found. her brain magnetic resonance imaging (mrï) and magnetic resonance venography (mrv) were normal as well. â...

Modern challenges of food science require a new understanding of the determinants of food quality and safety. Application of advanced imaging modalities such as magnetic resonance imaging (MRI) has seen impressive successes and fast growth over the past decade. Since MRI does not have any harmful ionizing radiation, it can be considered as a magnificent tool for the quality control of food prod...

Abstract. The availability of a benchtop nuclear magnetic resonance (NMR) spectrometer, low cost and easily transportable, can allow detection quantities biosensors, provided that hyperpolarized species are used. Here we show the micromolar threshold be reached by employing laser-polarized xenon cage molecules reversibly hosting it. Indirect caged is made via chemical exchange, using ultra-fast...

Abstract This paper proposes a baseline extraction method based on nuclear magnetic resonance atlas, which uses the DBSCAN algorithm to cluster data extracted by spectrometer and determines of atlas according clustering results. In this paper, core parameters are improved, Eps parameter set is selected combining k-dist equal interval division. The optimal number outliers obtained set, value ran...

kienbock's disease, which is an idiopathic osteonecrosis and collapse of the lunate bone, is an uncommon disease in children. this report describes a case of an 11-year-old girl, who presented with avascular necrosis of lunate bone confirmed by radiographic and magnetic resonance imaging evidence. after a short period of casting, the case was fully recovered within one year. the signal change w...

purpose: to assess the relationship between the severity of coronary arteries involvement and the extent and pattern of myocardial scars in cardiac magnetic resonance of patients with history of remote myocardial infarction. materials and methods: the cardiac magnetic resonance images of sixty patients with history of remote st segment or non-st segment elevation myocardial infarction were revi...

Recently, dynamic nuclear polarization enhanced nuclear magnetic resonance (DNP/NMR) has emerged as a powerful technique to obtain significant enhancements in spin spectra from biological samples. For DNP in modern NMR systems, a high power continuous-wave source in the submillimeter wavelength range is necessary. Gyrotrons can deliver tens of watts of CW power at submillimeter wavelengths and ...
