Researchers seeking new and more abundant sources of stem cells for use in regenerative medicine have identified a potentially unlimited, noncontroversial, easily collectable, and inexpensive source – menstrual blood.

Stromal stem cells - cells that are present in connective tissues - have recently been identified in endometrial tissues of the uterus. When the fresh growth of tissue and blood vessels is shed during each menstrual cycle, some cells with regenerative capabilities are present and collectable. While collecting menstrual blood stromal cells (MenSCs) directly from tissue would be invasive, retrieving them during the menstrual cycle would not be.

“Stromal stem cells derived from menstrual blood exhibit stem cell properties, such as the capacity for self-renewal and multipotency,” said Amit N. Patel, MD, MS, Director of Cardiac Cell Therapy at the University of Pittsburgh’s McGowan Institute of Regenerative Medicine. “Uterine stromal cells have similar multipotent markers found in bone marrow stem cells and originate in part from bone marrow.”

Eczema is a distressing condition for both parents and babies – the raw, red skin is painful to see and it is difficult to stop small children from scratching it. At worst, it can mean having to wet wrap wriggly toddlers each day with bandages soaked in moisturisers. It usually starts in the first year of life and affects about 10% of infants. Although most children eventually grow out of it, about half will go on to develop another allergic condition, such as asthma or hayfever.

Recent progress in understanding the role of gut bacteria in the development of the infant’s immune system has led to the hope that some of this suffering can be prevented in the future.

Remarkable new research into the way environmental factors affect the development of the brain has opened up the possibility that an infant’s future mental abilities and susceptibility to mental illness can be permanently altered by dietary changes in early life.

Evidence that changes in early diet can have long term effects on brain structure, verbal IQ, eyesight, appetite regulation and possibly on neurodevelopmental outcome will be presented at the international symposium on Early Nutrition Programming in Granada, Spain (23 April).

This is an area of research in which the EC is investing heavily as it offers huge potential in terms of improving the health and reducing health care costs of future generations. Neuropsychiatric disorders, such as depression, are the second most important cause of ill health in the EU after cardiovascular disease(1). The EC has already invested over €13 million in the Early Nutrition Programming Project (EARNEST) and has now committed another €6 million into the NUTRIMENTHE project (launched 22April 2008).

In 2001, religious fundamentalists destroyed two colossal, ancient Buddha statues in the Afghan region of Bamiyan. Behind those statues, there are caves decorated with artwork dating from the 5th to 9th centuries A.D and those also suffered from the destruction of the Taliban along with their natural environment, but recently they became the source of a major discovery.

Scientists at the European Synchrotron Radiation Facility (ESRF) have shown that the paintings were made of oil, hundreds of years before the technique was “invented” in Europe. The results were presented at a scientific conference in Japan last January and are just now published in the Journal of Analytical Atomic Spectrometry.

Red colobus monkeys in a park in western Uganda have been exposed to an unknown orthopoxvirus, a pathogen related to the viruses that cause smallpox, monkeypox and cowpox. Most of the monkeys screened harbor antibodies to a virus that is similar – but not identical – to known orthopoxviruses.

The study was begun in 2006 when Colin Chapman, a researcher at McGill University, invited Goldberg to collaborate on a health assessment of two groups of red colobus monkeys in Kibale National Park, in western Uganda.

Chapman, also an associate scientist with the Wildlife Conservation Society, had spent two decades studying the behavior and ecology of the monkeys. He wanted to broaden the study to include an analysis of the pathogens they carried. Wildlife veterinarians from the Wildlife Conservation Society helped collect the samples, and a team from Oregon Health and Science University, led by Mark Slifka, conducted immunological analyses to characterize the virus.

A new study has found that between 1983 and 1999, the death rate in women increased in a large number of the worst-off counties in the US, primarily because of chronic diseases related to smoking, high blood pressure, and obesity. As a result of this stagnation or decline in the health of the worst-off segment of the population, inequality in life expectancy across different counties of the US worsened.

Majid Ezzati of Harvard University and colleagues analyzed death rates in all counties of the US states plus the District of Columbia over four decades, from 1961 to 1999. They obtained data on number of deaths from the National Center for Health Statistics (NCHS) and data on the number of people living in each county from the US Census. NCHS did not provide data for subsequent years. They broke the death rates down by sex and by disease to assess trends over time for women and men, and for different causes of death.
