Scientists in America have made the first steps in identifying a group of genes which may be involved in the progression of breast cancer from non-invasive to invasive, the 3rd European Breast Cancer Conference in Barcelona heard today (Thursday 21 March).

Professor Craig Allred, Director of Breast Pathology at the Breast Center, Baylor College of Medicine, Houston, USA, used a technique called microarray to discover which genes might be involved in causing ductal carcinoma in situ (DCIS) to

Patients who are at high risk of stroke should be treated with the drug ramipril, irrespective of their initial blood pressure levels and in addition to other preventive treatments such as blood pressure lowering agents or aspirin, finds a study in this week’s BMJ.

Over 9,000 patients aged 55 or over and at high risk of stroke received either ramipril or placebo. Patients were seen after six months and then every six months for an average of four and a half years.

Although reductio

A US population study in this week’s issue of THE LANCET reports how life expectancy of people with Down’s syndrome has doubled since the early 1980s. The study also highlights the unexpected finding that Down’s syndrome appears to reduce the risk of many forms of cancer.

Down’s syndrome (characterised by three copies of chromosome 21) occurs in around one in every 800 live births. It is the most frequently identified cause of mental retardation, but information about illness and causes of d

Mushrooms (of course, those grown in an ecologically safe area) accumulate many microelements good for human and animal health, in particular, selenium. The natural cycle of selenium was studied by a team from the Vernadsky Institute of Geochemistry and Analytical Chemistry in Moscow.

The scientific expedition worked in the eastern part of the Meshchera (at the meeting point of the Moscow, Ryazan, and Vladimir areas). Scientists found selenium in many natural objects (soil, grass, le

For years scientists have been studying the impact of different geophysical fields on the earthquakes occurrence. It has been assumed that the fields, generated due to the solar activity, earth flows fluctuations, the Earth`s speed of rotation and even the launch of magnetohydrodynamic generators affect the strained state of the earth`s crust, these fields `pumping` additional energy into the crust. Normally the aroused earthquakes are recorded several days after the provoking key event.

Because living organisms contain millions of different molecules, identifying or separating any single one of these from their natural environment in order to carry out research work or perform diagnoses is quite like looking for a needle in a haystack. A number of molecular separation technologies are of course available, and are used by laboratories on a daily basis, but they are often unwieldy and costly. Scientists the world over are therefore attempting to develop a new generation of analytic de
