Men with multiple sclerosis pass disease to offspring more often than women
According to a new study, men transmit multiple sclerosis (MS) to their children 2.2 times more often than women in families where the father or mother and a child have multiple sclerosis. view more (2006-07-25)
Re-awakening old genes to help in the fight against HIV
A new vaginal cream containing a reawakened protein could someday prevent the transmission of HIV. view more (2009-04-28)
The pandemic potential of H9N2 avian influenza viruses
Since their introduction into land-based birds in 1988, H9N2 avian influenza A viruses have caused multiple human infections and become endemic in domestic poultry in Eurasia. view more (2008-08-13)
Vaccine Blocks Malaria Transmission in Lab Experiments
Researchers at the Johns Hopkins Malaria Research Institute have for the first time produced a malarial protein (Pfs48/45) in the proper conformation and quantity to generate a significant immune response in mice and non-human primates for use in a potential transmission-blocking vaccine. view more (2009-07-23)
Researchers link specific antibody presence to prevention of mother-to-baby HIV transmission
Exploring why some HIV-positive mothers transmit the virus in utero to their babies while others don't, researchers from the UCLA AIDS Institute and Los Alamos National Laboratory studied 38 infant-mother pairs in the UCLA arm of the Los Angeles Pediatric AIDS Consortium. view more (2006-07-12)
A brand new Microcar
The basque technological centre TEKNIKER has developed a brand new microcar to test all its capabilities in the micromanufacture. It is driven by an electric motor, the smallest in the market with an external diameter of 1.9 mm and longitude of 5 mm, a stator coil wound with 30 µm diameter wire and a rotor with permanent magnets. This micromotor... view more... (2004-07-29)
South African Government Urged To Take Action In Preventing Mother-To-Child HIV Transmission (p 992)
Leading South African scientists, writing in a Commentary in this week's issue of THE LANCET, are calling on their government to implement antiretroviral drug programmes without delay to reduce the vertical transmission of HIV-1 infection from pregnant women to their children. Around 75,000 South African children were born with HIV-1 infection in... view more... (2002-03-20)
Local climate influences dengue transmission
Researchers from the US Centers for Disease Control and Prevention (CDC) and the Johns Hopkins Bloomberg School of Public Health have found that dengue transmission in Puerto Rico is dependent upon local climate and short-term changes in temperature and precipitation. view more (2009-02-17)
Challenges of HIV-1 subtype diversity
A review article in the New England Journal of Medicine explores the genetic variation of HIV-1 and its implications for preventing and treating the disease. Francine McCutchan, Ph.D., a researcher with the U.S. Military HIV Research Program, co-authored the article, which appeared in the April 10, 2008 edition. view more (2008-05-22)
Dog Collars Could Prevent Parasitic Disease In Children
Children could be protected from a potentially lethal parasitic disease if dogs were fitted with insecticide-impregnated collars, suggest authors of a study in THE LANCET this week. Zoonotic visceral leishmaniasis is caused by transmission of a parasite, Leishmania infantum, from animals (mostly domestic dogs) by blood-sucking sandflies. In... view more... (2002-07-31)
Zinc plays important role in brain circuitry
To the multitude of substances that regulate neuronal signaling in the brain and spinal cord add a new key player: zinc. By engineering a mouse with a mutation affecting a neuronal zinc target, researchers have demonstrated a central role for zinc in modulating signaling among the neurons. view more (2006-11-27)
Variant of mad cow disease may be transmitted by blood transfusions, according to animal study
Blood transfusions are a valuable treatment mechanism in modern medicine, but can come with the risk of donor disease transmission. Researchers are continually studying the biology of blood products to understand how certain diseases are transmitted in an effort to reduce this risk during blood transfusions. view more (2008-08-29)
The Role Of Sexually Transmitted Diseases, Malaria, And Tuberculosis On The Hiv-1/Aids Epidemic In Africa (p 2177)
The effect of HIV-1 on other infectious diseases in Africa is an increasing public health concern. In a review in this week's issue of THE LANCET, Elizabeth Corbett from the London School of Hygiene and Tropical Medicine, UK, and the Harare Biomedical Research and Training Institute, Zimbabwe, and colleagues describe the role that three major... view more...

Tuberculosis breaches borders, but not public health
Immigrants from countries with high rates of tuberculosis who move to countries of low TB incidence do not pose a public health threat to native citizens, according to researchers in Norway, who analyzed the incidence and genetic origins of all known cases of TB in the country between 1993 and 2005. view more (2007-11-01)
Derwent Information Annual Uk Company Patent Study Shows High-tech Companies Dominate Innovation
London, United Kingdom - The Derwent Information annual study into the number of basic patents filed in the UK during 2001 shows that technology companies dominated innovation. Derwent Information research reveals that out of the top ten ranked companies, by number of basic* patents filed, six filed a large number in the engineering technology... view more... (2002-07-01)
How breastfeeding affects HIV transmission
Mother to child transmission of HIV accounts for a large proportion of HIV infections in children, with many infected as a result of breastfeeding, which requires transfer of the virus across mucosal barriers. view more (2005-10-21)
Many pregnant women avoid HIV screening in Africa
'Prevention is the best cure' is a common expression, but what happens if preventative measures are not used? A large proportion of pregnant Ugandan women are going out of their way not to be HIV tested, increasing the risk of mother-to-child transmission. view more (2009-11-20)
Pre-chewed food could transmit HIV
Researchers have uncovered the first cases in which HIV almost certainly was transmitted from mothers or other caregivers to children through pre-chewed food. view more (2009-07-22)
Study: Indirect transmission can trigger influenza outbreaks in birds
New data on the persistence of avian influenza viruses in the environment has allowed a team of University of Georgia researchers to create the first model that takes into account both direct and indirect transmission of the viruses among birds. view more (2009-06-03)
A possible ancient origin for tuberculoses in Casablanca
Each year tuberculosis kills about three million people in the world. In particular it is responsible for the death of more than one-third of HIV- infected people, who prove particularly susceptible owing to a decline in immune defences. The agent responsible is a bacterium of the species Mycobacterium tuberculosis, also termed Koch's bacillus,... view more... (2004-11-23)
