Use of glucagon-like polypeptide 2 analogs for intestinal failure.

Introduction: Over a half century ago, a component of glucagon was found to have potent gastrointestinal effects. Shortly after proglucagon was sequenced, its component peptides were characterized, and glucagon-like polypeptide-2 (GLP-2) was noted to have the most potent intestinotrophic properties improving fluid and electrolyte balance in experimental animals and humans.

Areas Covered: Glucagon-like polypeptide-1 (GLP-1) slows small intestinal motility more effectively, but its intestinotrophic properties are weaker.

Morphology and line tension of twist disclinations in a nematic liquid crystal.

We deploy optical microscopy with and without an applied magnetic field to characterize the three-dimensional morphology and measure the line tension of twist disclinations in twisted nematic liquid crystal (LC) sample cells. Twist disclinations are generated by quenching the LC, 5CB (4-cyano-4'-pentylbiphenyl), into the nematic phase; 5CB is confined between substrates with in-plane anchoring directions perpendicular to one another. The disclinations form loops separating domains of opposite twist handedness.

Tuning Chemical DNA Ligation within DNA Crystals and Protein-DNA Cocrystals.

Biomolecular crystals can serve as materials for a plethora of applications including precise guest entrapment. However, as grown, biomolecular crystals are fragile in solutions other than their growth conditions. For crystals to achieve their full potential as hosts for other molecules, crystals can be made stronger with bioconjugation.

An automatic glucose monitoring system based on periplasmic binding proteins for online bioprocess monitoring.

Glucose is one of the most vital nutrients in all living organisms, so its monitoring is critical in healthcare and bioprocessing. Enzymatic sensors are more popular as a technology solution to meet the requirement. However, periplasmic binding proteins have been investigated extensively for their high sensitivity, enabling microdialysis sampling to replace existing complex and expensive glucose monitoring solutions based on enzymatic sensors.

Red cell abnormalities characterized by ektacytometry in children with cholestasis.

Background: Spur-cell anemia sometimes accompanies cholestasis. We postulated that even in the absence of spur-cells, cholestasis might alter red blood cell (RBC) osmotic fragility and deformability. Therefore, we assessed these RBC measures by ektacytometry in pediatric patients.
