A PSE toolkit can be deemed as a group of technologies within a software architecture through which multiple PSEs can be built for different application domains. This paper presents a metadata model for Grid-based PSE toolkits and the architecture of an information system based on the metadata management model. These two components contributed to the definition of a general model of metadata ma...

From the methanolic extract of the underground parts of Globularia orientalis, a new antioxidant sugar ester was isolated. The structure of the new compound, globularitol (1), was identified as 6-O-feruloyl-beta-D-glucopyranosyl-(1-->6)-glucitol by spectroscopic methods (1D and 2D NMR, ESI- and FAB-MS) and confirmed by chemical means.

( ) ABSTRACT: The industrial and sanitary use of dithiocarbamates DTCs is on the rise, and the synthesis of new derivatives has increased the field of their application. Both positive and negative pharmacological and toxicological effects have been documented for DTCs. The development and application of new DTCs must be accompanied by the study of their toxicity, beginning with the performance ...

A rapid, sensitive and selective high-performance liquid chromatography-tandem mass spectrometric method (HPLC-MS) was developed and validated to determine the 14-(3-methylbenzyl)matrine (3MBM) and 14-(4-methylbenzyl)matrine (4MBM) levels in rat plasma in the present study. The analytes were separated using a C18 column (1.9 μm, 2.1 mm × 100 mm) equipped with a Security Guard C18 column (5 μm, ...

Known as an occupational disease, chronic manganese intoxication is recently being observed among abusers of psychoactive substances. Methcathinone hydrochloride is obtained by combining ephedrine/pseudoephedrine and potassium permanganate. Various neuropsychiatric symptoms have been reported among Efedron users. Our patient is a 29 year old male, who was referred to our hospital from a state g...

Background Oral histamine receptor–1 antagonists, such as fexofenadine, offer suboptimal relief of allergic rhinitis-associated nasal congestion. Combinations with oral sympathomimetics, such as pseudoephedrine, relieve congestion but produce side effects. Histamine receptor-3 antagonists, such as PF-03654764, reduce congestion in animals and have been proposed as novel therapeutics. Previous n...

We present a case of fetal tachycardia associated with maternal use of long-acting pseudoephedrine, an over-the-counter decongestant. No previous studies exist on pseudoephedrine or other over-the-counter decongestants and their effect on the fetal heart. The elevated fetal heart rate led to difficulty in interpreting a nonstress test. The normal human fetal heart rate at term is 110 to 160 bea...

A total of 466 healthy adults from four different regions of England entered a double-blind, randomised trial to test the effectiveness of an antihistamine (triprolidine) and a decongestant (pseudoephedrine), alone or in combination, in relieving symptoms of the common cold. During the study 199 subjects reported a total of 243 colds. Subjects recorded the severity of 12 symptoms during treatme...
