Abstract A 51-year-old woman presented with one-month history of fever, productive cough, dyspnea, hoarseness and polyarthritis. Computed tomography (CT) depicted diffuse bronchotracheal stenosis, which deteriorated in exhalation. Three-dimensional CT revealed airway stenosis from the trachea to the lobar bronchi. We made a diagnosis of relapsing polychondritis (RP). Administration of high-dose ...

In brain perfusion imaging, arterial spin labeling (ASL) is a noninvasive alternative to dynamic susceptibility contrast-magnetic resonance imaging (DSC-MRI). For clinical imaging, only product sequences can be used. We therefore analyzed the performance of a product sequence (PICORE-PASL) included in an MRI software-package compared with DSC-MRI in patients with steno-occlusion ...

Two virulence factors produced by Vibrio cholerae, cholera toxin (CT) and toxin-corregulated pilus (TCP), are indispensable for cholera infection. ToxT is the central regulatory protein involved in activation of CT and TCP expression. We previously reported that lack of a respiration-linked sodium-translocating NADH-ubiquinone oxidoreductase (Na(+)-NQR) significantly increases toxT transcription. In ...

The [(18)F]FDG has 109.7min half-life, there is a period about 6h between the beginning of [(18)O]H2O irradiation until the PET-CT exam. Any fail in production chain will result in delay to the PET-CT exam. The absence of the position signs from [(18)O]H2O target valve may result in (18)F production loss. ...

A 64-year-old right-handed Caucasian presented with a four-year history of word-finding deficits and otherwise fluent speech production. Neurological examination remained unremarkable apart from the word finding impairment. Likewise, neuropsychological evaluation confirmed significantly reduced semantic word fluency. While brain MRI depicted only discrete anterior temporal atrophy, 18-fluorodeoxyglucose PET showed clear hypometabolism ...

Vibrio cholerae is a gram-negative bacterium that causes cholera. Although the pathogenesis caused by this deadly pathogen takes place in the intestine, commonly thought to be anaerobic, anaerobiosis-induced virulence regulations are not fully elucidated. Anerobic growth of the V. cholerae strain, N16961, was promoted when trimethylamine N-oxide (TMAO) was used ...

Cushing syndrome (CS) is a rare condition, with an incidence of 2 to 4 cases per million inhabitants per year. In most cases of CS, elevated adrenocorticotropic hormone (ACTH) secretion results in excess adrenal gland cortisol secretion but usually this is from pituitary, not ectopic ACTH production. We present a ...

Cushing's syndrome (CS), first described by the neurosurgeon Harvey Cushing in the 1930s, is the result of chronic glucocorticoid excess. In patients with adreno-corticotropic hormone (ACTH)-dependent CS, bilateral hyperplasia of the adrenal cortex occurs, while in those with ACTH-independent primary CS, either adrenocortical tumors or primary adrenal hyperplasia can be ...

Background: The measurement of adrenal gland size on computed tomography (CT) scan has been proposed for the etiological diagnosis of hyperadrenocorticism (HAC) in dogs. Symmetric adrenal glands are considered to provide evidence for ACTH-dependent hyperadrenocorticism (ADHAC), whereas asymmetry suggests ACTH-independent hyperadrenocorticism (AIHAC). However, there are currently no validated criteria for ...

Hereditary and sporadic neurodegenerative ataxias are movement disorders that affect the cerebellum. Robust and objective biomarkers are critical for treatment trials of ataxias. In addition, such biomarkers may help discriminate between ataxia subtypes because these diseases display substantial overlap in clinical presentation and conventional MRI. Profiles of 10-13 neurochemical concentrations ...

Immediate and delayed cerebellar dysfunction may be expected after surgical resection of a medulloblastoma. We investigated whether pre-operative and delayed post-operative MRI may correlate with such sequelae. The data of 31 patients in continuous complete remission after removal of medulloblastoma, irradiation and chemotherapy, were retrospectively reviewed. Magnetic Resonance Imaging (MRI) ...

Several explanations have been suggested to account for the failure of extracorporeal shockwave lithotripsy (ESWL) treatment in patients with urinary stones, including large stone volume, unfavorable stone location or composition and the type of lithotriptor used. Unfavorable stone composition is considered a major cause of failure of ESWL treatment, and ...

Dual energy X-ray absorptiometry (DEXA) is a reference method for assessing body composition but is seldom `accessible in veterinary settings. Computed tomography (CT) can provide similar body composition estimates and we propose that it can be used in body composition studies in animals. We compared CT and DEXA data from ...

Increasing evidence for a cerebellar role in human cognition has accrued with respect to anatomically and functionally distinct lobules. Questions of laterality, however, have been largely overlooked. This study therefore introduced and applied a novel measurement protocol for comparatively bias-free analysis of cerebellar asymmetries. Volumetric measurements were performed on magnetic ...

Spinocerebellar ataxia (SCA17) is a rare genetic disorder characterized by a variety of neuropsychiatric symptoms. Recently, using magnetic resonance imaging (MRI) voxel-based morphometry (VBM), several specific functional-structural correlations comprising differential degeneration related to motor and psychiatric symptoms were reported in patients with SCA17. To investigate gray matter volume (GMV) changes ...
