The DTL ERG electrode comes in different shapes and sizes: Are they all good?

Purpose: Although the DTL fiber electrode has been in use in the ERG field for more than four decades, its composition was never clearly defined. We compared five different types of conductive (DTL type) yarn (differing in terms of mass, number of filaments, and crimping degree) in order to determine whether we could identify one that would be better suited for the recording of ERGs.

Methods: Photopic flash ERGs were recorded from five subjects using the following DTL electrodes: 27/7, 22/1, 11/1, 11/1*2, and 22/1*2.

Synthesis of AZT-based cationic lipids and in vitro evaluation of siRNA delivery.

New types of cationic lipids based on AZT were evaluated for their biological effects in terms of their cytotoxicity and their cellular delivery of siRNA.
