The quest for an effective HIV vaccine presents new possibilities, challenges

..., the first successful preventive HIV vaccines, if administered prior to HIV infection, may reduce HIV levels in the body, thereby delaying the progression to AIDS and the need to start antiretroviral drugs. These vaccines may also reduce the chance that a person infected with HIV would pass the virus on to other...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...the researchers found that when SNO compounds were administered to mice they could prevent the receptors from being "turned off" by the drugs. The researchers said these findings, if confirmed in humans, open up new avenues for the development of non-desensitizing drugs not only for heart failure and asthma bu...

Peramivir protects mice from lethal H5N1 infection

...nce versus twice). In all cases, the investigators administered peramivir to mice one hour after nasally administering a lethal Vietnam strain of H5N1 influenza virus. The researchers reported 100 percent survival among 10 infected mice given intramuscular injections of peramivir daily for eight days. The drug...

How brain pacemakers erase diseased messages

... School of Engineering have found that stimulation administered by rapid-fire electrical pulses deep in the brain produces what they call an "informational lesion." By relaying a repetitious and therefore meaningless message, constant pulses overwhelm the erratic bursts of brain activity characteristic of disease...

Avian influenza survivors' antibodies effective at neutralising H5N1 strain

...the lab and the moderate doses required." Using administered antibodies has a historical precedent. During the 1918 Spanish H1N1 influenza pandemic, there were multiple reports of physicians administering blood taken from survivors to patients infected with the disease. A recent review suggested that this trea...

New vaccine prevents CMV infection and disease in mice

...roved, commercially licensed hCMV vaccine could be administered to specific at-risk populations, such as females prior to child-bearing years, day care providers, organ transplant recipients, or as part of regular childhood immunizations. “This approach may also be valid for a number of diseases associated wi...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

...ra finches. They surprisingly found that when they administered testosterone implants to zebra finches that it acted as a stimulant to the immune system. They went on to show that carotenoids acquired from food and circulating through the blood were changing in ways that were linked to testosterone levels. Birds ...

Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model

...inserted. Four weeks after the treatment, rats administered HSV-GDNF exhibited significant recovery of intracavernous pressure (ICP) and systemic arterial pressure (AP) compared with rats treated with the control virus or untreated mice with ED. Rats treated with HSV-neurturin also exhibited significant recov...
