Women addicted to crack cocaine need many support services

A Penn State researcher found that nearly three-fourths of women addicted to crack cocaine engage in prostitution to support their habit, highlighting the need for comprehensive support services. The study suggests that programs should offer housing, education, and job training to help these women escape poverty and addiction

Scientist show how viruses co-opt cell defenses to cause chronic infections likethose from HIV and Hepatitis B and C

Researchers have developed a model to study viral evasion and co-option of cellular defense strategies, revealing that persistent infection is achieved by suppressing cell suicide. Physiological changes occur, including slower growth and reduced virus infectivity over time.

Advanced light source uncovers new clues to high-temperature superconductivity

Researchers used angle-resolved photoemission spectroscopy to study the electronic structure of Nd-LSCO, finding charge carriers segregated into one-dimensional lines and exhibiting quantum fluctuations that give rise to two-dimensional effects. This discovery may help resolve a paradox between different theories of superconductivity.

New database on HIV/AIDS to focus on real-world treatment outcomes

The new HIVWatch database, developed at UC San Francisco, tracks real-world treatment outcomes for patients with HIV disease. Preliminary data show an increase in CD4 cells among patients at their first clinic meeting, but a stable viral load, suggesting further analysis is needed.

Jefferson scientists show drug is effective against a Hepatitis C Virus model in the laboratory

Researchers at Thomas Jefferson University and Oxford University have found a promising drug against the hepatitis C virus (HCV), called N-nonyl-DNJ, which inhibits the activity of an important cellular enzyme, glucosidase. This drug may sidestep resistant viruses, a major problem with current treatments.

Brain releases marijuana-like substance in response to pain, study finds

A study by Brown researchers has found that the brain releases a naturally produced cannabinoid called anandamide in response to pain. The substance produces analgesia and may provide a new approach to treating chronic pain, particularly in cases where opiates are ineffective.
