The aim of this study was to investigate the value of T(2) (*)-weighted gradient echo imaging (GRE T(2) (*)-WI) for the detection of familial cerebral cavernous malformation (FCCM). Twenty-six members of 2 families with FCCM were examined using computed tomography (CT), conventional magnetic resonance imaging (MRI) and GRE T(2) (*)-WI sequences. We identified 12 cases of FCCM using GRE T(2) (*)...

The invasion of epithelial cells by Salmonella enterica serovar Typhimurium is a very tightly regulated process. Signaling cascades triggered by different environmental and physiological signals converge to control HilD, an AraC regulator that coordinates the expression of several virulence factors. The expression of hilD is modulated at several steps of the expression process. Here, we report ...

Objective In this study we investigate the association between the expression of inflammatory mediators measured in clots retrieved by mechanical thrombectomy, stroke etiology, and the susceptibility vessel sign (SVS) on gradient-echo (GRE) MR imaging in acute ischemic stroke patients. Methods We performed molecular analysis of intracranial clots retrieved by mechanical thrombectomy from 82 p...

We present findings of genetic information conservation between the glucocorticoid response element (GRE) DNA and the cDNA encoding the glucocorticoid receptor (GR) DNA-binding domain (DBD). The regions of nucleotide sub-sequence similarity to the GRE in the GR DBD occur specifically at nucleotide sequences on the ends of exons 3,4, and 5 at their splice junction sites. These sequences encode t...

BACKGROUND Improved delineation of vascular structures is a common indication for cardiovascular magnetic resonance (CMR) in children and requires high spatial resolution. Currently, pre-contrast 3D, respiratory navigated, T2-prepared, fat saturated imaging with a bSSFP readout (3D bSSFP) is commonly used; however, these images can be limited by blood pool inhomogeneity and exaggeration of meta...

Functionally graded material (FGM) is an advanced class of composite material. In FGM, the volume fraction each constituent can be tailor-made across thickness for desired applications. this paper, analytical solution and numerical simulation free vibration transient heat conduction problem in a functionally pipe are considered. 3D elasticity theory adopted considering effect natural frequency ...

Generation of Referring Expressions (gre) is a key task of Natural Language Generation nlg systems (e.g., Reiter and Dale, 2000, section 5.4). The task of a gre algorithm is to find combinations of properties that allow the generator to refer uniquely to an object or set of objects, called the target of the algorithm. Older gre algorithms tend to be based on a number of strongly simplifying ass...

OBJECTIVE The T2(*)-weighted gradient echo image susceptibility vessel sign (GRE SVS) is a well-known indicator of intraluminal thrombi in acute cerebral infarction. The purpose of this study was to evaluate the relationships between thrombus size on GRE SVS and recanalization after intravenous administration of tissue plasminogen activator (IV-tPA). MATERIALS AND METHODS Fifty five patients ...

BACKGROUND AND PURPOSE Vestibular schwannomas (VS) may be difficult to differentiate from cerebellopontine angle (CPA) meningiomas. Demonstration of microhemorrhages in VS on T2*-weighted gradient-echo (GRE) sequences may have potential value to differentiate VS from CPA meningiomas. MATERIALS AND METHODS In this prospective study of 20 patients, MR imaging was performed with T2*-weighted GRE...
