Meningitis outbreaks As Africa enters the dry season

As Africa enters the dry season, meningitis outbreaks have reported. The so-called 'meningitis belt' is a massive strip of Africa, travelling east to west, parallel to the Sahara desert and covering sub-Saharan countries from Senegal to Ethiopia.

Genetic trick makes gene therapy vectors more versatile

A genetic trick used by viruses to replicate themselves has been adapted for laboratory use to build complex protein structures required by immune system cells, according to investigators at St. Jude Children’s Research Hospital.

Completion of the sequencing of human chromosome 19

The United States Department of Energy (DOE) Joint Genome Institute (JGI) and Stanford University report today the completion of the sequencing of human chromosome 19, the most gene-rich of all the human chromosomes. This achievement is described in the April 1, 2004 edition of the journal Nature.

Scientists studying vaccinia virus, a relative of smallpox, have determined that a gene necessary for virus replication also has a key role in turning off inflammation

Scientists at the University of Illinois at Urbana-Champaign studying vaccinia virus, a close relative of smallpox, have determined that a gene necessary for virus replication also has a key role in turning off inflammation, a crucial anti-viral immune response of host cells.

New York - Due to changing blood donor criteria, donor deferral rates have been increasing since 1999

Due to changing blood donor criteria, donor deferral rates have been increasing since 1999 with trend lines predicting additional deferral increases. This predicament has created a critical demand for new people to step forward to donate to ensure there is an adequate supply of blood for hospital patients in New York and New Jersey who require life-saving transfusions, reports New York Blood Center (NYBC) officials.

The first human case of avian influenza A(H7) in British Columbia

The first human case of avian influenza A(H7) in British Columbia occurred in a person who was involved in culling of infected birds on 13-14 March. On 13 March, he may have been accidentally exposed in the eye. On 16 March, the individual reported conjunctivitis and nasal discharge. Treatment with oseltamavir, an antiviral drug active against influenza A viruses, began on 18 March. On 30 March, Health Canada concluded that this case was caused by avian influenza A(H7). Health Canada informed WHO of this case on 31 March. The patient's symptoms have fully resolved.

Compounds that may stop replication of T-cell leukemia virus

Researchers are analyzing several compounds that may inhibit the enzyme that is essential for the reproduction of the Human T-cell Leukemia Virus Type 1 (HTLV-I), which has infected 15 to 20 million people worldwide. The virus causes the fatal adult T-cell leukemia in up to 10 percent of those infected.

SARS virus vaccine stimulates protective immune response

An experimental vaccine prevents the SARS virus from replicating in laboratory mice, according to a new report in the April 1 issue of Nature. Scientists at the Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health, developed the vaccine. The vaccine was tested in a mouse model of SARS infection recently validated by other NIAID investigators.

Newly diagnosed non-Hodgkin’s lymphoma linked to monkey virus DNA

Examination of tumors in patients with newly diagnosed non-Hodgkin’s lymphoma found that half of them show evidence of a monkey virus DNA that may have originated from contaminated polio vaccines.

Chinese testing of Hepatitis B rapid test kit complete

Medical Services International Inc. is pleased to announce that it has completed a second set of testing of its Hepatitis B rapid test kit in the People's Republic of China.

Researchers tap modified plant viruses to ward off cervical cancer-causing infections

New vaccinations to prevent infections that lead to cervical cancer and targeted therapeutics aimed at breast cancer were examples of research highlights presented by scientists today at the 95th Annual Meeting of the American Association for Cancer Research. Scientists described advances that feed into the drug development 'pipeline,' and show strong promise for controlling existing tumors or addressing the pathogen that causes tumors.

Researchers have successfully grafted human breast tissue into the mammary glands of mice

The last few years have witnessed critical advances in breast cancer therapies. Still, the disease afflicts one in eight American women, and scientists have yet to develop a living model with which they can study the intricacies of human breast-tumor behavior.

p53 protein peptide stops cancer in its tracks

Researchers have dreamed of thwarting cancer by using proteins that halt cell growth and kill the tumor. In theory, the approach should work. In practice, however, scientists have not had an easy time of getting tumor suppressor proteins into cells where they can block growth effectively.

Asthma study turns up new information on viral infections

Researchers know that viral infections can exacerbate asthma and, in turn, make people with the condition more sensitive to environmental exposures such as endotoxin. But how viral infections contribute to this sensitivity in airway cells has not been clear. A recent study led by investigators from the University of Iowa Roy J. and Lucille A. Carver College of Medicine and the Veterans Affairs Medical Center (VAMC) in Iowa City shows, for the first time, that viral infections may increase environmental sensitivity in lung epithelial (surface) cells by changing expression of receptors on those cells.

£5m for HIV/AIDS trial involving HIV patients in London, Moscow, South Africa and Australia

A joint Oxford University/Imperial College research programme into HIV/AIDS has received £5 million support from the Wellcome Trust to carry out a drug trial involving HIV patients in London, Moscow, South Africa and Australia.

First US Tests of Bird-Flu Vaccine in Humans

Doctors are beginning the first test in the United States of a vaccine designed to protect people against one form of bird flu should an outbreak of the virus occur in humans. While the vaccine under study is not designed to protect against the precise bird-flu virus causing the current outbreak in poultry and in people, scientists will learn whether it protects against another strain of the virus that infects birds and people.

New Cell Sorter Helps Understand Deadly Diseases

Researchers at NC State’s College of Veterinary Medicine have a new state-of-the-art tool, a high-speed cell sorter, that should quicken the pace of their research. The machine sorts or collates cells into groups, allowing scientists to look only at the cells they are working on.
