Addressing Health Disparities Through Voter Engagement.

Although the public's essential capacity for self-rule in the United States lies in the power of the ballot, there exist many barriers to voting, particularly for marginalized communities. These barriers cultivate less representative government and less inclusive public policy. Nonprofit and private health organizations, and in particular community health centers and safety-net hospitals, can help marginalized voting-eligible individuals overcome barriers to the ballot.

HIV prevention: A 3-pronged approach.

HIV infection may not command the headlines it once did, but the public health threat it poses is still formidable. These steps can help us get ahead of it.

RAS-RAF-MEK-dependent oxidative cell death involving voltage-dependent anion channels.

Therapeutics that discriminate between the genetic makeup of normal cells and tumour cells are valuable for treating and understanding cancer. Small molecules with oncogene-selective lethality may reveal novel functions of oncoproteins and enable the creation of more selective drugs. Here we describe the mechanism of action of the selective anti-tumour agent erastin, involving the RAS-RAF-MEK signalling pathway functioning in cell proliferation, differentiation and survival.
