DNA vaccines get a boost

High blood pressure, sepsis, and snake bites might all be cured by the same antidote, according to Schneider et al. (page 2629). High blood pressure and septic shock are both enhanced by a 21–amino acid peptide called ET-1. This peptide is secreted by blood vessel cells that have been activated by inflammatory cytokines. ET-1 triggers the contraction of smooth muscle cells that are wrapped arou...

A New Topology of Embedded Z-H Buck-Boost Converter

In this paper, a new embedded Z-H (EZ-H) buck-boost converter is proposed. In this topology, two identical dc voltage sources are embedded in a LC network in a series connection with the inductors. The proposed converter eliminates the shoot-through (ST) switching state and there is no need for a front-end diode. Other advantages of the proposed topology are having capability of buck and boost ...
