CHIRAL WATER-SOLUBLE MOLECULAR CAPSULES WITH AMPHIPHILIC INTERIORS

We present the synthesis of new chiral water-soluble dimeric capsules here by the multicomponent Mannich reaction between charged amino acids (glutamic acid or arginine), resorcinarene, and formaldehyde and by subsequent self-assembly.The zwitterionic character of the backbones enables electrostatic interactions between arms and induces self-assemb

Objective:We aimed to evaluate the pattern of beetroot birkenstock neck metastasis in patients with primary tonsillar carcinoma treated by primary surgery and neck dissection.Impact of the extent of neck dissection and level of metastatic nodes on survival were also evaluated.Methods:We evaluated 163 consecutive patients with tonsillar squamous cel
