Prehistoric origins of stomach ulcers uncovered
February 08, 2007An international team of scientists has discovered that the ubiquitous bacteria that causes most painful stomach ulcers has been present in the human digestive system since modern man migrated from Africa over 60,000 years ago. The research, published online today (7 February) by the journal Nature, not only furthers our understanding of a disease causing bacteria but also offers a new way to study the migration and diversification of early humans.
The international research collaboration was led by scientists from the University of Cambridge, the Max Planck Institute in Berlin, and the Hanover Medical School. The researchers compared DNA sequence patterns of humans and the Helicobacter pylori bacteria now known to cause most stomach ulcers. They found that the genetic differences between human populations that arose as they dispersed from Eastern Africa over thousands of years are mirrored in H. pylori.
Human DNA analysis has shown that along the major land routes out of Africa human populations become genetically isolated-the further from Eastern Africa a population is the more different genetically it is compared to other human populations. Other research has shown gradual differences in European populations, presumed to be the result of Neolithic farmers moving northwards. The international H. pylori research team found almost exactly the same genetic distribution patterns in their results.
The scientists combined their genetic analysis with a computer simulation the modelled the spread of the bacteria across the globe. This showed that it migrated from Eastern Africa at almost exactly the same time as early humans, approximately 60,000 years ago.
The UK research effort was led by Dr Francois Balloux, a Biotechnology and Biological Sciences Research Council-funded scientist at the University of Cambridge. He said: "Humans and this ulcer-causing bacterium have been intimately linked for the last 60,000 years. The research not only shows the likelihood that for tens of thousands of years our ancestors have been suffering the effects of this bacteria but it also opens up new possibilities for understanding early human migration. By showing that Helicobacter pylori emerged from Africa at the same time as early humans it makes it easier to examine some of the controversial questions about human migration. For example we could use our understanding of the bacteria's spread to gauge poorly understood human population shifts in Europe, Africa and Asia."

Propolis has proved to be a product with ability to have beneficial effects for health
Growing concerns about health has caused the scientific community to focus their interest on investigating functional foods which contribute to boosting the prevention and reduction of the risk of suffering from certain illnesses.
Simple measures may prevent transmission of stomach ulcer bacteria
The stomach ulcer bacterium Helicobacter pylori is not transmitted through drinking water as previously thought, but rather through vomit and possibly faeces.
Slight Fluorescence Gives Hope For Recovery
Stomach ulcer not only aches, it also fluoresce. Russian researchers believe that the brighter the fluorescence is, the less chances the patient has to do without the operation.
High Probability Diagnostics
A lot of diseases are known to the medical science, each of the diseases having its own symptoms. Nevertheless, all diseases have something in common, regardless of the illness cause and the patients` individual reactions. These generalised regularities inherent in all diseases are called general pathology. Physicians can easily recognise anatomical and physiological abnormalities, but some symptoms are not evident. These abnormalities appear to be a presage of a disease, and after the recovery they are retained for some time by the organism as a reminder of the disease. The signs of such asymptomatic pathology are, brought to light, with the help of biochemical, immunological, biophysical,

Living with Ulcers/GERD (Home Use) Part of the award winning public television series Healthy Body/Healthy Mind. More than 50 million people living in the US experience occasion al heartburn, but for more than 25 million people, heartburn has become an annoying part of life. If this sounds familiar, your "heartburn" may be a symptom of a serious digestive disorder called GERD or Gastro Esophageal Reflux disease. Another digestive disorder identified as peptic ulcers is attributed in many cases to a bacteria found in the stomach called h-pylori. Doctors believe that the h-pylori bacteria have evolved with humans over the past 5 million years. In this program, we take an in depth look at GERD/Ulcers and all the options currently available to treat these disorders. This product is manufactured on demand using DVD-R... |
