How Ebola virus infects cells - discovery

Ebola virus reproduction in laboratory-grown cells is severely hampered by enzyme-inhibiting chemicals, and these chemicals deserve further study as possible treatments for Ebola virus infections in humans, report scientists supported in part by the National Institute of Allergy and Infectious Diseases (NIAID).

UK plan for influenza pandemic

The HPA Influenza Pandemic Contingency Plan outlines the Health Protection Agency’s plan for responding to an influenza pandemic. It replaces the Public Health Laboratory Service Pandemic Influenza Plan of July 2001.

Almost all killer flu bug kits destroyed

99 percent of the kits containing a killer flu bug that mistakenly ended up in thousands of laboratories around the world, sparking fears of a pandemic, have been destroyed, according to top U.S. health official Dr. Julie Gerberding, director of the Centers for Disease Control and Prevention (CDC).

Researchers make gains in understanding antibiotic resistance

Howard Hughes Medical Institute researchers chiseling away at the problem of antibiotic resistance now have a detailed explanation of how the drugs' main cellular target in bacteria evolves to become resistant to some of these medications.

Discovery may lead to new drugs to prevent sexually transmitted HIV infection

Scientists have long suspected that HIV hijacks immune cells called dendritic cells to infiltrate the immune system. Now UCLA AIDS Institute researchers have shown that blocking HIV's access to a naturally occurring molecule on dendritic cells may cut their ability to smuggle the virus into other immune cells.

Strongest evidence yet that infectious misformed proteins cause mad cow disease

Researchers at the University of Texas Medical Branch at Galveston (UTMB) have produced the strongest proof yet that the mysterious and devastating brain diseases known as "transmissible spongiform encephalopathies" (TSEs) are transmitted by an infectious agent composed only of a malformed protein, and not a virus.

Official Indian AIDS figures in dispute

A claim by AIDS expert Richard Feachem, that India now has the most HIV-positive people in the world has been dismissed by the Indian government.

Missing samples of deadly flu strain now found

World Health Organization (WHO) officials say that all but one of the deadly flu virus samples mistakenly sent to labs outside the United States have been destroyed.

New gene linked to familial cancer

Scientists have identified a new gene that appears to be linked to a small but significant percentage of familial cancer cases – as well as seemingly randomly occurring malignancies.

Breast cancer gene may play a major role in the recurrence of prostate cancer

A gene associated with breast cancer also may play a major role in the recurrence of prostate cancer, according to new research from the University of North Carolina at Chapel Hill School of Medicine and UNC Lineberger Comprehensive Cancer Center.

Concern over H2N2 freeze-dried powder being available over the Internet

The World Health Organization fears that a global pandemic could occur should the H2N2 virus, the "Asian flu" strain of 1957, be unwittingly released, the virus which was mistakenly included in routine test kits and sent to 61 laboratories in 18 countries outside the United States.

Researchers insert engineered human stem cells into the spinal cords of ALS-afflicted rats

Unveiling a delivery method that may one day help surgeons treat the deadly neurodegenerative disease amyotrophic lateral sclerosis (ALS), researchers at the University of Wisconsin-Madison have inserted engineered human stem cells into the spinal cords of ALS-afflicted rats.

Stress can give the immune system a beneficial boost

New research in mice provides more evidence that a brief bout of stress can give the immune system a beneficial boost – under certain conditions.

Scientists reveal the shape of a protein that helps retroviruses break into cells

Retroviruses are among the trickier and more malicious disease agents, causing AIDS and cancers such as leukemia. The viruses manage to sneak into cells with the help of special protein assemblies scattered all over their surfaces. These retrovirus surface proteins cause the membrane envelope of the virus to fuse with the membrane of the cell, spilling virus RNA into the cell to wreak damage.

Test kit mistake - labs in race to destroy deadly flu virus

As many as 3,750 medical laboratories, all but 75 of which are in the U.S., have been told by the World Health Organization to destroy a pandemic flu virus sent to them as part of routine testing kits.

Scientists have discovered the mechanism that enables some CD4 T cells - the main target of HIV - to thwart the virus

The discovery, reported on April 13 in the online version of Nature, could open the door to an entirely new strategy for preventing the spread of HIV infection in the body's cells, according to the senior author of the study, Gladstone Institute of Virology and Immunology Director Warner C. Greene, MD, PhD.

Rates of cervical cancer could jump fourfold to a million a year by 2050

Deaths from cervical cancer could jump fourfold to a million a year by 2050, mainly in developing countries. This could be prevented by soon-to-be-approved vaccines against the virus that causes most cases of cervical cancer- but there are signs that opposition to the vaccines might lead to many preventable deaths. The trouble is that the human papilloma virus (HPV) is sexually transmitted.

Marburg outbreak - experts struggling to get message across

Disease experts in Angola say it will be weeks before it is determined whether the on-going Marburg crisis can be averted in Angola where the disease has already killed at least 194 people.
