The ability of meningococci bacteria to change their cell surface proteins could reduce the effectiveness of the current meningitis C vaccine. Now scientists are working on vaccines that would allow us to co-exist happily with these microbes, according to research presented today (Monday 08 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.
“We have identified several proteins secreted by meningococci, which are involved in causing diseas
A vaccine has been developed, which could prevent inflammation and illness caused by certain bacterial infections following major surgery, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.
Dr Elliott Bennett-Guerrero, Chief of Cardiac Anesthesia at Columbia University College of Physicians & Surgeons, New York, USA says, “Severe inflammation caused by bacterial toxins is becoming recognised as an importa
Signs of virus from human faeces found in bottled water.
Mineral water is marketed for its purity. But Swiss scientists are claiming that some brands may be contaminated with human faeces.
In 11 of 29 European brands of bottled mineral water Christian Beuret and colleagues of the Cantonal Food Laboratory in Solothurn found signs of the virus that causes more than 90% of the world’s stomach upsets 1 , 2 . The virus is called Norwalk-like virus
Approximately 375,000 Europeans suffer cardiac arrest every year – often with fatal consequences. Even upon successful resuscitation, several patients suffer severe and irreparable brain damage. One in seven patients could be saved and the amount of serious damage resulting from cardiac arrest could be drastically reduced by reducing the body temperature of those affected to between 32 and 34 degrees in the first 24 hours following the cardiac arrest. Such are the results of a Europe-wide study, in w
Research by Dr Mark Nieuwenhuijsen published in the journal Occupational and Environmental Medicine today (4 April) highlights an area of potential risk to pregnant women through exposure to the by-products of chlorination in swimming pools.
The following statement clarifies the potential risk:
Dr Nieuwenhuijsen, from the Department of Environmental Science and Technology at Imperial College, London says:
“There is no empirical evidence that chlorination by-products in swimming
New evidence in this week’s BMJ supports the use of up to three antiviral drugs (triple therapy) to treat people with HIV.
Researchers in Birmingham reviewed 54 trials involving over 20,000 patients with HIV infection who had not already received antiviral therapy.
Combinations of up to three drugs were consistently and significantly more effective, but there was inadequate evidence on the effectiveness of quadruple or higher combinations. There was also marked variation, mainly acc
Common allergens (such as dust mite and grass pollen) and viruses may act together to exacerbate asthma, concludes a study in this week’s BMJ.
Sixty patients (aged 17 to 50) admitted to hospital over a year with acute asthma were matched with two controls: patients with stable asthma and patients admitted to hospital with non-respiratory diseases (inpatient controls). Skin tests for dust mite, cat, dog, and grass allergens were performed on all patients.
A significantly higher propo
Results of a Dutch study in this week’s issue of THE LANCET highlight how a male genital disorder could be more common among boys born to mothers who were prenatally exposed to a synthetic hormone withdrawn in the late 1970s.
The drug diethylstilbestrol (DES) was previously prescribed to prevent spontaneous abortion and preterm delivery. DES was withdrawn in the 1970s when it became clear that it was associated with vaginal cancer and fertility disorders in women who were exposed to the drug
A US randomised trial in this week’s issue of THE LANCET suggests that vitamin C and E supplementation could be of clinical benefit in delaying the onset of arteriosclerosis in the first year after heart transplantation.
Around 70% of patients develop arteriosclerosis within three years after heart transplantation, which is thought to be associated with oxidant stress. James Fang and colleagues from Brigham and Women`s Hospital, Boston, USA, proposed that treatment with antioxidant vitamins
Scientists make strides in the study of women’s sports injuries.
Straighter legs and knock-knees may be causing female athletes to tear knee ligaments more frequently than males. The finding could help coaches to shape women’s training to reduce such injuries.
When researchers at the University of North Carolina spotted that women land with their knees straighter and closer together than do men, they asked the athletes to spring on and off platforms that measure force in sev
Severe headaches are not a sign of high blood pressure, as is commonly thought, finds research in the Journal of Neurology Neurosurgery and Psychiatry. If anything, high blood pressure seems to reduce the risk of these headaches, the study shows.
The findings are based on the blood pressure readings of over 22,000 adults who responded to a survey 11 years later in 1995 to 1997 about headache frequency.
The questionnaire showed that 28 per cent of them suffered repeated headaches, of
Both HIV-1 and HIV-2 are of zoonotic origin , and the closest simian relatives of HIV-1 and HIV-2 have been found in the common chimpanzee (Pan troglodytes) and the sooty mangabey (Cercocebus atys) respectively. Given that humans come in frequent contact with primates in many parts of subsaharan Africa, particularly through hunting and handling primate bushmeat the possibility of additional zoonotic transfers of primate lentiviruses from species other than chimpanzees and sooty mangabeys has to be co
Scientists have developed a blood test that may reveal changes in the brain caused by Alzheimer’s disease. The technique, tested so far only in mice, predicts the amount of amyloid plaque (formed from clumps of proteins that kill surrounding cells) in an animal’s brain. The research, detailed in a report in the current issue of the journal Science, holds promise for the development of predictive methods to diagnose the disease years ahead of the onset of clinical symptoms.

Women with early breast cancer could avoid needless chemotherapy thanks to work carried out in Chicago on identifying biochemical markers which indicate whether or not cancer is likely to spread to other parts of the body, the 3rd European Breast Cancer Conference in Barcelona heard today (Saturday 23 March).
Ruth Heimann, Associate Professor in the department of radiation and cellular oncology at the University of Chicago, USA, said that patients with early breast cancer which has not sprea
The first clinical trial in Europe of a revolutionary approach to diagnosing breast cancer has just got under way at one of the UK’s leading breast cancer centres.
The research involves a minute endoscope, no thicker than a few strands of human hair, which can pass through the nipple and search for the earliest signs of cancer within the breast.
Consultant breast surgeon, Dr Nicolas Beechey-Newman from Guy’s Hospital in London, told a news briefing at the 3rd European Breast Cancer Confe
Swedish stem cell researchers are in a good position to become even more successful than in recent years. This can be achieved by improving the collaboration between research groups, and by increasing the number of researchers in the field through, for example, the introduction of “come-home” grants for those who have been abroad. Equally important would be economic commitment to basic research on stem cells, and the creation of regulations for emergent commercial aspects so that researchers can main
