VaporSPOT: Parallel Synthesis of Oligosaccharides on Membranes.

Automated chemical synthesis has revolutionized synthetic access to biopolymers in terms of simplicity and speed. While automated oligosaccharide synthesis has become faster and more versatile, the parallel synthesis of oligosaccharides is not yet possible. Here, a chemical vapor glycosylation strategy (VaporSPOT) is described that enables the simultaneous synthesis of oligosaccharides on a cellulose membrane solid support.

Automated Laser-Transfer Synthesis of High-Density Microarrays for Infectious Disease Screening.

Laser-induced forward transfer (LIFT) is a rapid laser-patterning technique for high-throughput combinatorial synthesis directly on glass slides. A lack of automation and precision limits LIFT applications to simple proof-of-concept syntheses of fewer than 100 compounds. Here, an automated synthesis instrument is reported that combines laser transfer and robotics for parallel synthesis in a microarray format with up to 10 000 individual reactions cm .

Probing Multivalent Carbohydrate-Protein Interactions With On-Chip Synthesized Glycopeptides Using Different Functionalized Surfaces.

Multivalent ligand-protein interactions are a commonly employed approach by nature in many biological processes. Single glycan-protein interactions are often weak, but their affinity and specificity can be drastically enhanced by engaging multiple binding sites. Microarray technology allows for quick, parallel screening of such interactions.

On-Chip Neo-Glycopeptide Synthesis for Multivalent Glycan Presentation.

Single glycan-protein interactions are often weak, such that glycan binding partners commonly utilize multiple, spatially defined binding sites to enhance binding avidity and specificity. Current array technologies usually neglect defined multivalent display. Laser-based array synthesis technology allows for flexible and rapid on-surface synthesis of different peptides.

Multivalent glycan arrays.

Glycan microarrays have become a powerful technology to study biological processes, such as cell-cell interaction, inflammation, and infections. Yet, several challenges, especially in multivalent display, remain. In this introductory lecture we discuss the state-of-the-art glycan microarray technology, with emphasis on novel approaches to access collections of pure glycans and their immobilization on surfaces.

The iSCREEN Electronic Diabetes Dashboard: A Tool to Improve Knowledge and Implementation of Pediatric Clinical Practice Guidelines.

Objectives: Clinical practice guidelines (CPG) provide evidence-based recommendations for patient care but may not be optimally applied in clinical settings. As a pilot study, we evaluated the impact of a computerized, point-of-care decision support system (CDSS) on guideline knowledge and adherence in our diabetes clinic.

Methods: iSCREEN, a CDSS, integrated with a province-wide electronic health record, was designed based on the Canadian Diabetes Association 2013 Clinical Practice Guidelines for the Prevention and Management of Diabetes in Canada.

Celiac Disease Alone and Associated With Type 1 Diabetes Mellitus.

Objectives: The aim of the study was to evaluate complication screening and follow-up patterns in a population with type 1 diabetes mellitus and celiac disease (T1D/CD) in relation to a matched cohort with celiac disease (CD) alone at our center.

Methods: We retrospectively reviewed the health charts of 41 children with T1D and biopsy-proven CD and compared anthropometrics and complication of screening within 2 years from CD diagnosis. Follow-up patterns were determined 3 years postdiagnosis.

Despite a high prevalence of menstrual disorders, bone health is improved at a weight-bearing bone site in world-class female rhythmic gymnasts.

Context: Regular physical activity during puberty improves bone mass acquisition. However, it is unknown whether extreme intense training has the same favorable effect on the skeleton.

Objective: We evaluated the bone mass acquisition in a unique cohort of world-class rhythmic gymnasts.

Complications of chronic liver disease.

Children with chronic liver disease (CLD) need a head to toe approach and an early suspicion of multi organ involvement. Nutritional assessment and management is the cornerstone of management. Consider immune dysfunction in everyday treatment decisions.
