UNMC's ART injectables can successfully treat HIV infection

This has been a good week for breakthroughs in HIV/AIDS. Earlier this week, the Food and Drug Administration approved a daily pill, Truvada, which reduces the risk of HIV infection. Today, a University of Nebraska Medical Center research team's progress toward developing weekly or twice-monthly injectable antiretroviral therapy (ART) nanomedicines for patients with human immunodeficiency virus (HIV) infection will be highlighted as the cover story in the Journal of Infectious Diseases.

Inhibiting STAT3 might unleash an effective anti-lymphoma immune response

Researchers at Moffitt Cancer Center and colleagues have demonstrated that the inhibition of signal transducer and activator of transcription 3 (STAT3) in mouse models of mantle cell lymphoma (MCL), an aggressive and incurable subtype of B-cell non-Hodgkin lymphoma that becomes resistant to treatment, can harness the immune system to eradicate residual malignant cells responsible for disease relapse.

Combination of Dox with MCP shows promise against prostate cancer

Doxorubicin (Dox) is an effective anti-cancer drug, but it's also a very toxic one, causing severe heart and immune damage. The doses needed to impact tumors are not well tolerated by patients, however, researchers may have found an answer through combination therapy.

Healthier levels of vitamin C can reduce inflammatory conditions

The recommended dietary allowance, or RDA, of vitamin C is less than half what it should be, scientists argue in a recent report, because medical experts insist on evaluating this natural, but critical nutrient in the same way they do pharmaceutical drugs and reach faulty conclusions as a result.
