A new blended learning concept for medical students in otolaryngology.

Objective: To evaluate students' overall assessment and effectiveness of the web-based blended learning conception "Unified Patient Project" (UPP) for medical students rotating on their otolaryngology internship (ear, nose, and throat [ENT] tertiary).

Design: Prospective comparison group design of the quasiexperimental type.

Setting: Medical education.

Cellular localization and subcellular distribution of Unc-33-like protein 6, a brain-specific protein of the collapsin response mediator protein family that interacts with the neuronal glycine transporter 2.

Unc-33-like protein (Ulip)6, a brain-specific phosphoprotein of the Ulip/collapsin response mediator protein family, was originally identified in our laboratory by yeast two-hybrid screening using the cytoplasmic N-terminal domain of the neuronal glycine transporter, glycine transporter (GlyT) 2, as a bait. Here, the interaction of Ulip6 with the N-terminal domain of GlyT2 was found to be specific for this member of the Ulip/collapsin response mediator protein family and to involve amino acids 135-184 of GlyT2. In pull-down assays and coimmunoprecipitation experiments with rat spinal cord extract, the presence of phosphatase inhibitors significantly enhanced binding of Ulip6 to GlyT2.

Chronic double lumen intravenous cannulation of the unrestrained rat.

Chronic double lumen intravenous cannulation was performed on the rat. The cannulation system consisted of a pulley assembly, protective tube, mounting post, and a double lumen cannula. Using a double lumen expanded catheter, a two-channel connection was made with the rat's vascular system through a single entry into the external jugular vein.
