BACKGROUND AND PURPOSE The modified Rankin Scale (mRS) is the most prevalent outcome measure in stroke trials. Use of the mRS may be hampered by variability in grading. Previous estimates of the properties of the mRS have used diverse methodologies and may not apply to contemporary trial populations. We used a mock clinical trial design to explore inter- and intraobserver variability of the mRS...

Age is an important risk factor for stroke, and carotid artery stenosis is the primary cause of first-ever ischemic stroke. Timely intervention with stenting procedures can effectively prevent secondary stroke; however, the impact of stenting on various periprocedural physical functionalities has never been thoroughly investigated. The primary aim of this study was to investigate whether preste...

To assess quantitatively phosphocreatine (PCr), adenosine triphosphate (ATP) and total creatine (CR) in asynergic regions of ischemic human myocardium using phosphorus (31P) and proton magnetic resonance spectroscopy (1H MRS). Patients were divided into two groups: 31P MRS and 1H MRS. In each group, patients were subdivided into three groups using echocardiography: a normokinetic [WN(P) (n = 6)...

31-phosphorous ((31)P) magnetic resonance spectroscopy (MRS) is a technique that allows the noninvasive characterization of the biochemical and metabolic state of the myocardium in vivo. MRS is a pure form of molecular imaging using magnetic resonance signals from nuclei with nuclear spin to assess cardiac metabolism without the need for external radioactive tracers. (31)P MRS provides informat...

We give polynomial-time algorithms for satisfiability and enumeration of underspecified semantic representations in a canonical form. This canonical form brings several underspecification formalisms together into a uniform framework (Manshadi et al., 2008), so the algorithms can be applied to any underspecified representation that can be converted to this form. In particular, our algorithm can ...

The present study was carried out to assess the frequency of methicillin-resistant staphylococci (MRS) among racehorses (n=209) and veterinary personnel (n=13) as well as environmental surfaces (n=14) at an equine hospital in Adana, Turkey. In addition, species distribution, antimicrobial susceptibility, resistance genes, staphylococcal chromosomal cassette mec (SCCmec) type and clonality of th...

Cholinergic muscarinic receptors (MRs) and monoamine oxidase activity (MAO-B), expressed both in brain and blood cells, were investigated in animals and exposed subjects to assess (i) MeHg (0.5-1 mg/kg/day GD7-PD7) and/or PCB153 (20 mg/kg/day GD10-GD16) effects on cerebellar MAO-B and MRs, and lymphocyte MRs, in dams and offspring 21 days postpartum; (ii) MAO-B in platelets and MRs in lymphocyt...

non-invasive technique that provides information about metabolites present in brain tissue. Thus, the use of MRS may potentially raise the diagnostic specificity and improve the diagnostic capacity of magnetic resonance imaging (MRI). Since MRS may provide additional information about patient prognosis and response to treatment, MRS has recently become a prevalent technique (1-3). It is rare to...

BACKGROUND The objective of this study was to evaluate the efficacy of proton magnetic resonance spectroscopy (1H-MRS) in the detection of prostate cancer. MATERIALS AND METHODS The experimental group consisted of 20 patients with localized prostate cancer who underwent radical prostatectomy. The sensitivity, positive predictive value and accuracy of the detection of prostate cancer in the 12...
