Viral protein influences key cell-signaling pathway

...al protein." HTLV-1 infects an estimated 15 to 20 million people worldwide. In about five percent of them, the infection will lead to adult T cell leukemia or lymphoma (ATLL). ATLL is an aggressive disease characterized by a long latent period and the proliferation of T lymphocytes. The virus is spread by s...

Molecular models advance the fight against malaria

...rrently at risk of the disease and approximately 2 million people, mostly children, are killed by malaria annually worldwide. Today marks Africa Malaria Day, organized to promote awareness of the disease in a country where a child is killed every 30 seconds by malaria. Investigating ways to counter the muta...

Reducing malarial transmission in Africa

There are 300 million cases of malaria each year worldwide, causing one million deaths. Around 90% of these deaths occur in Africa, mostly in young children. One of the greatest ch...

ELISAs do not have the sensitivity required to detect ADDLs in cerebrospinal fluid. BCA could eventually be configured to detect hundreds of diseases simult...

Insight into natural cholesterol control suggests novel cholesterol-lowering therapy

...esterol-lowering statins--taken by an estimated 10 million people each day to protect against coronary artery disease and reduce the incidence of heart attacks--limit cholesterol synthesis by inhibiting reductase function, he said. As a result, cells take up more cholesterol from the bloodstream, lowering it...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...lenium-polluted soil. "Field conditions involve a million different variables, from weather to soil conditions, so results can be radically different than those in the lab," said Norman Terry, professor of plant and microbial biology at UC Berkeley's College of Natural Resources and co-lead author of the st...
