Surgical treatment of an abnormally positioned right adrenal tumor on segmental caudal vena cava aplasia in two dogs.

Segmental caudal vena cava (CVC) aplasia is a rare congenital vascular anomaly in dogs. Two dogs were diagnosed by CT imaging to have right adrenal tumors with concomitant segmental CVC aplasia. During surgery, a firm connection between the right adrenal gland and CVC was observed in both cases.

Synthesis and Glycan-Protein Interaction Studies of -Sialosides by Se NMR.

To expand the potential of carbohydrates for multifunctional mimicry of sugars, herein we addressed the synthesis of the highly challenging and biologically significant glycosides of sialic acid (sialosides). An α-sialyl selenolate anion generated in situ smoothly reacted with electrophiles to give α-sialosides as single stereoisomers. A -sialoside was sequentially incorporated with selenium, producing a triseleno-sialoside.

Compartmentalized host spaces accommodating guest aromatic molecules in a chiral way in a helix-peptide-aromatic framework.

A novel host molecular assembly of a free-standing flat nanosheet with compartmentalized spaces was prepared using a bolaamphiphilic peptide composed of two amphiphilic helical peptides and an oligo(naphthaleneethynylene) (ONE) unit at the center of the molecule. The nanosheet possesses void host spaces that can accommodate two mol-equivalent ONE groups to form columns of ONE groups in a right-handed helical way and ONE channels over a long distance. The present molecular system therefore can provide a chiral pore channel for relatively large molecules.
