The development of an outcome measure for liaison mental health services.

Unlabelled: Aims and methodTo develop and pilot a clinician-rated outcome scale to evaluate symptomatic outcomes in liaison psychiatry services. Three hundred and sixty patient contacts with 207 separate individuals were rated using six subscales (mood, psychosis, cognition, substance misuse, mind-body problems and behavioural disturbance) plus two additional items (side-effects of medication and capacity to consent for medical treatment). Each item was rated on a five-point scale from 0 to 5 (nil, mild, moderate, severe and very severe).

EUROCarbDB: An open-access platform for glycoinformatics.

The EUROCarbDB project is a design study for a technical framework, which provides sophisticated, freely accessible, open-source informatics tools and databases to support glycobiology and glycomic research. EUROCarbDB is a relational database containing glycan structures, their biological context and, when available, primary and interpreted analytical data from high-performance liquid chromatography, mass spectrometry and nuclear magnetic resonance experiments. Database content can be accessed via a web-based user interface.

Information management for proteomics: a perspective.

Proteomics is a data-rich discipline that makes extensive use of separation tools, mass spectrometry and bioinformatics to analyze and interpret the features and dynamics of the proteome. A major challenge for the field is how proteomics data can be stored and managed, such that data become permanent and can be mined with current and future tools. This article details our experience in the development of a commercial proteomic information management system.

Development of a mass fingerprinting tool for automated interpretation of oligosaccharide fragmentation data.

The bioinformatic tool GlycosidIQ was developed for computerized interpretation of oligosaccharide mass spectrometric fragmentation based on matching experimental data with theoretically fragmented oligosaccharides generated from the database GlycoSuiteDB. This use of the software for glycofragment mass fingerprinting obviates a large part of the manual, labor intensive, and technically challenging interpretation of oligosaccharide fragmentation. Using 130 negative ion electrospray ionization-tandem mass spectrometry fragment spectra from identified oligosaccharide structures, it was shown that the GlycosidIQ scoring algorithms were able to correctly identify oligosaccharides in the great majority of cases (correct structure top ranked in 78% of the cases and an additional 17% were ranked second highest in the sample set).

Does an isolated history of loss of consciousness or amnesia predict brain injuries in children after blunt head trauma?

Background: A history of loss of consciousness (LOC) is frequently used as an indication for cranial computed tomography (CT) in the emergency department (ED) evaluation of children with blunt head trauma.

Objective: We sought to determine whether an isolated LOC and/or amnesia is predictive of traumatic brain injury (TBI) in children with blunt head trauma.

Methods: We prospectively enrolled children <18 years old presenting to a level I trauma center ED between July 1998 and September 2001 with blunt head trauma.

A decision rule for identifying children at low risk for brain injuries after blunt head trauma.

Study Objective: Computed tomography (CT) is frequently used in evaluating children with blunt head trauma. Routine use of CT, however, has disadvantages. Therefore, we sought to derive a decision rule for identifying children at low risk for traumatic brain injuries.

GlycoSuiteDB: a curated relational database of glycoprotein glycan structures and their biological sources. 2003 update.

GlycoSuiteDB is an annotated and curated relational database of glycan structures reported in the literature. It contains information on the glycan type, core type, linkages and anomeric configurations, mass, composition and the analytical methods used by the researchers to determine the glycan structure. Native and recombinant sources are detailed, including species, tissue and/or cell type, cell line, strain, life stage, disease, and if known the protein to which the glycan structures are attached.

Glycosylation of acetylxylan esterase from Trichoderma reesei.

The nature of the N- and O- linked glycosylation of acetylxylan esterase (AXE) of the Trichoderma reesei strain Rut-C30 has been characterized using different enzymatic, chromatographic, and mass spectrometric techniques. The combined data showed that the AXE N-glycan is phosphorylated and highly mannosylated. The predominant N-glycans on the single glycosylation site on AXE can be represented as GlcNAc(2)Man((1-6))P.
