HIV hides from drugsUC Davis scientists have discovered that the human immunodeficiency virus, the virus that causes AIDS, is able to survive efforts to destroy it by hiding out in the mucosal tissues of the intestine. They also observed that HIV continues to replicate in the gut mucosa, suppressing immune function in patients being treated with antiretroviral treatment--even when blood samples from the same individuals indicated the therapy was working.

Diagnosis And Referrals For Kidney DiseaseResults of a national study of 304 U.S. physicians, in which "mock" patients' symptoms were presented for diagnosis, suggest that a sizeable percentage of primary care doctors probably fail to properly diagnose and refer patients with chronic kidney disease (CKD).

Genetic Model For Parkinson's DiseaseIn the mouse model generated by the research team, a gene called TFAM is automatically deleted from the genome in dopamine nerve cells only. Without TFAM, mitochondria cannot function normally. The so called respiratory chain is compromised and energy production decreases severely in the dopamine cells.
The new mice are born healthy from healthy but genetically modified parents and will develop spontaneous disease. Prior studies in the field........Go to the Neurology news blog (Added on 7/29/2006 8:47:02 PM)

New Genetic Findings To Understanding Of OCDObsessive-compulsive disorder tends to run in families, causing members of several generations to experience severe anxiety and disturbing thoughts that they ease by repeating certain behaviors.
