Use of high hydrostatic pressure to inactivate Hepatitis A virus in oysters studied

..., immunosuppressed people, and those with existing liver disease. Bivalve shellfish, such as oysters, have been demonstrated to concentrate pathogenic organisms from their environment. In some cases, sewage contamination of harvesting areas, either from coastal runoff or ship discharges, has been shown to...

Hurricane aftermath: Infectious disease threats from common, not exotic, diseases

...a threat to people with weakened immune systems or liver dysfunction. The CDC has confirmed 15 infections with V. vulnificus, 3 of which were fatal. These cases have occurred in areas other than New Orleans where the water has greater salinity. Another concern is diarrhea and gastrointestinal illnesses fr...

Corn grain mould used as pesticide

...itous. This may be one reason for the high rate of liver cancer in Africa. "Our colleagues from the IITA in Nigeria recently succeeded in proving that 99 out of 100 children from Benin and Togo had aflatoxin in their blood," Professor Richard Sikora of the Bonn Institute of Plant Diseases explains. "The co...

Firefly protein lets researchers monitor molecule linked to cancer

Discarded placentas deliver researchers promising cells similar to embryonic stem cells

...amnion-derived cells could differentiate to become liver cells, heart cells, the glial and neuronal cells that make up the nervous system, and pancreatic cells with genetic markers for insulin and glycogen production. "In this first paper we sought to determine if amniotic epithelial cells have the potent...

Does manganese inhaled from the shower represent a public health threat?

...en, pregnant women, the elderly, and patients with liver disease are at highest risk from manganese toxicity. Some of these groups have developed manganese poisoning even at fairly low doses in their water supplies, Spangler said. The Environmental Protection Agency (EPA) has set 0.5 milligrams/liter as t...

Researchers discover key to human embryonic stem-cell potential

...o take these blank slates and coax them into, say, liver or brain tissue. But in order to guide them out of pluripotency with efficiency, we need to know what keeps them there to begin with. Researchers in the Whitehead laboratories of Young, Rudolf Jaenisch, MIT-computer scientist David Gifford, and the...

Perhaps even more impressive was the improvement in endurance and lifespan of the treated versus the untreated hamsters. The AAV-8-treated hamsters were able...

Zebrafish, however, are a fascinating species because the fish embryos are literally transparent and can be directly observed at early developmental stages better than almost any other animal species. They had been...

Past illegal blood donation in China linked to hepatitis C virus infection

...rn about health effects of blood drawing, abnormal liver function tests or hepatitis, and shut-down of the illegal blood center. The investigators concluded that unhygienic plasma donation and receipt of blood transfusion are strong risk factors for HCV infection in rural central China, and that improved ...

Magnetic probe successfully tracks implanted cells in cancer patients

Yuan said he has applied for a provisional patent covering this new use of poloxamer 407, which his group purchased from the BASF Corp. In 2003, Yuan, Wang, Krol, Li and other Duke...

Sperm stem cells closer to being like embryonic stem cells

Furthermore, added Victor Hesselbrock, professor of psychia...

PET imaging reveals the immune system at work

...xample, it may not tell you what's going on in the liver or the spleen. With this technique, the sensitivity for monitoring the immune system is incredible because you're seeing the whole body." That global perspective makes it possible to see critical ancillary responses in addition to the specific cellu...
