The extrapontine myelinolysis of osmotic demyelination syndrome (ODS) is a well-known but uncommon disorder of the central nervous system. Although the mechanism is not fully understood and the treatment is controversial, hyponatremia is probably considered to be the main pathophysiological basis. There are few reports of ODS caused by a sellar lesion. Here we present a case of suprasellar arac...

OBJECTIVE To evaluate the impact of using a novel optical detection system (ODS) as an adjunct to colposcopy. METHODS A multicenter internally controlled trial designed to evaluate the performance of an ODS system (LUMA MediSpectra, Lexington, MA) used as an adjunct to colposcopy among women referred for the evaluation of an abnormal cervical cytology result was conducted at 7 colposcopy clin...

There have been many studies conducted on online discussion sites (ODS) but studies related to the user interface of ODS is lacking. User interface design of ODS plays an important role in increasing user experiences. Thus this study aims to propose a suitable methodology for designing ODS for emotional user experiences. Emotional user experiences towards a design generally use a single investi...

A sulfur transfer agent in catalysts can effectively reduce the emission of SO2 with minimum adverse effects on the catalytic cracking ability of the primary catalyst. In this paper, the composition and performance of sulfur transfer agents with different oxidative active components (such as Cu, Fe, Ni, Co, Ba, Zn and Cr) were prepared by acid peptization technique and characterized by X-ray di...

Dependencies play an important role in database theory. We study order dependencies (ODs)—and unidirectional order dependencies (UODs), sub-class of ODs—which describe the relationships among lexicographical orderings of sets of tuples. We investigate the inference problem for order dependencies. We establish the following: (i) a sound and complete chase procedure for ODs for testing logical im...

Two pathways are recognized for the activation of dihydrogen by metal catalysts, homolytic and heterolytic. Homolytic activation involves oxidative addition to metals usually in low oxidation states. Heterolytic activation, which occurs with no formal change in oxidation state, is associated with metals in higher oxidation states and gives rise to hydridic (H-, usually attached to a metal) and ...
