The National Cancer Institute, a unit of the National Institutes of Health in Bethesda, Md., said research from its molecular targets discovery program was published in Antiviral Research highlighting the discovery that a bacterial protein known to reduce HIV's ability to infect cells also inhibits infection by the Ebola virus. The antiviral protein, cyanovirin-N (CV-N), was found to extend the survival time of Ebola-infected mice. CV-N comes from a type of bacterium known as cyanobacterium, or blue-green algae.

• PanaMed Corp., of Indianapolis, reported initial results from the first stage of a six-month treatment program for its HIV/AIDS immunomodulating drug, Viro-net. Results from the African study, consisting of 22 patients who ranged from 4 to 43 years old, demonstrated that all HIV patients tolerated and responded well to the treatment. Overall, the general health of a statistically significant number of patients improved: lesions and rashes subsided; blood pressures returned to normal levels; appetites increased; and subsequent weight gain was notable, the company said. Blood test results indicated a statistically significant reduction in viral load measurements in 93 percent of patients that began the program with a CD4 count of 400 or less.

• Repligen Corp., of Waltham, Mass., said its board adopted a shareholders rights plan under which all shareholders as of March 17 will receive rights to purchase shares of a new series of preferred stock. The plan is intended to guard against coercive takeover tactics and is not in response to any particular proposal, it said. Repligen focuses on pediatric developmental disorders, including autism and immune and metabolic disorders.

• Sarawak MediChem Pharmaceuticals Inc., of Woodridge, Ill., completed a 48-subject clinical trial of Calanolide A in combination therapy for HIV.
