Research team develops nonhuman primate model of smallpox infection

...gues examined the host gene expression patterns of hemorrhagic smallpox in these animals. Specifically, they documented fluctuations in cellular proliferation, interferon, and viral modulation of the immune response. A better understanding of the disease process that occurs with smallpox infection will aid in th...

According to the 1999-2000 National Health and Nutrition Examination Survey, an estimated 13.5 percent of women in the U.S. take vitamin E supplements, although it is not known how many are taking the vitamin to prevent heart disease and str...

The cost of dengue fever challenges public health and national economies

...ch person hospitalized with dengue fever or dengue hemorrhagic fever in Malaysia costs about $718 to treat. About 70 percent of the cost is paid for by the government, and the rest by insurers and individual households. This cost per patient is equivalent to 53 days of lost economic output, according to the stud...

42 biomedical scientists worldwide named HHMI international research scholars

Tuberculosis, malaria, hemorrhagic fevers, and anthrax all are infectious and parasitic diseases posing a global problem that calls for a global solution. So the Howard Hughes Medical Institute (HHMI) is awarding $17.5 million to 42 outstanding scientists in 20 countries to tackle the...

Secrets to antibody's success against West Nile Virus surprise scientists

... virus and may be important to the onset of dengue hemorrhagic fever. This theory suggests that dengue and other viruses may have developed tricks that let them reproduce inside macrophages, the immune cells that normally consume and destroy any object that they find covered in antibodies. In effect, these tri...

Computer models aid understanding of antibody-dependent enhancement in spread of dengue fever

...Enhanced virus replication triggers a more deadly, hemorrhagic form of the disease. A study published in the online edition of Proceedings of the National Academy of Sciences suggests that antibody-dependent enhancement offers an evolutionary trade-off between advantage and disadvantage for the dengue virus. The...
