Hantavirus found in African wood mouse

...iscovered in Slovenia. The researchers have also grown the virus in cell culture, which is notoriously difficult to do with hantaviruses. Now they can easily test to see which antibodies react with the virus and how strongly they react. Antibody reactivity comparisons are another way to determine genetic...

Botox could help target resistant tumors for treatment

...mor. Botox was injected into the tumor once it had grown to about 6 mm. The tumors were then examined for three days, for vascular and perfusion changes as well as responses to anti-cancer therapies. In tests on oxygenation, cellular oxygen pressure was shown to significantly increase after treatment by Bo...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...a specific patient. Dr. Schaer says the cells are grown in culture to very high numbers, allowing a single donor's cells to treat thousands of patients. "The cells have the ability to expand, or multiply, under controlled conditions, and the expanded cells have the ability to develop into different types ...

Growing crops to cope with climate change

...the global climate changes. The varieties of crops grown in the UK are suited to the soil, seasons and traditional cool, wet summers. Later flowering in barley means it has a longer growing period to amass yield. If British summers get hotter and drier we will need types of wheat, barley and other crops th...

Defective immune system response to smallpox vaccine detailed in new study

...tis skin. Comparing immune responses of skin cells grown in the lab from healthy volunteers and from people with atopic dermatitis, the researchers found that the latter skin samples produced excessive amounts of IL-4 and IL-13. Adding IL-4 and IL-13 to skin cells from healthy volunteers prior to vaccinia...

World's pledge to halve hunger by 2015 looks like empty promise

...s reduced its poverty levels, hunger worldwide has grown in more than half of the developing countries since 1990. In fact, the number of hungry people in sub-Saharan Africa has jumped 20 percent since then, says Pinstrup-Andersen, who also chairs the Science Council of the Consultative Group on Internatio...

Researchers release new variety of asparagus

...own ?the root system of an asparagus plant that is grown from seed. The crown is planted about a foot deep in sandy soils. Spears grow from buds in the crown, and, if not harvested, branch out to form the "fern" which is the feathery green leaves and stems of the plant. Spears are not usually harvested un...

New nano-canary in the nanotoxicology coalmine: The body itself

...meeting. "Our process requires that live cells be grown on an infrared transparent substrate giving us an opportunity to closely examine the biological effects in living cells," said Sundaram. Live cell Fourier transform infrared, FTIR, spectroscopy offers several attractive features for these investigat...

New DNA 'fingerprinting' technique separates hemp from marijuana

...ijuana plants with genetic markers. Hemp, a crop grown for durable fiber and nutritious seed, and marijuana, the most abundant illegal drug of abuse in the United States, both belong to the species Cannabis sativa. They differ in levels of the psychoactive drug tetrahydrocannabinol (THC) but are otherwis...

Testes to incubate stem cells

... stem cells found in testicles could be extracted, grown in the lab, and frozen for future use. A team in the Netherlands has successfully harvested spermatogonial stem cells from cows and cultured them inside mouse testes. The hope is that the same thing could be done for men. "This is a very promising ro...

Clues to breast cancer hidden inside stem cells

...he Faculty of Medicine, University of Iceland have grown three-dimensional breast cell cultures to reveal unexpected subtleties about these stem cells that could explain why they spawn malignancies. These stem cells, Valgardur Sigurdsson remarked during the EuroSTELLS Conference in Venice, Italy (19-21 M...

Environmental metagenomics diagnosing extreme environments, tapping opportunities for clean energy

...e vast majority of microbes are resistant to being grown under standard laboratory conditions. Through the emerging strategy of metagenomics--isolating, sequencing, and interpreting the DNA extracted directly from the environment in question, an informative window opens onto that important and underutilize...

Driver of anthrax toxicity could lead to late-stage therapy

...the extracellular domain of LRP6 can protect cells grown in culture against killing by anthrax toxin suggest that the immunological targeting of LRP6 may prove useful in protecting against the effects of accumulated toxin during the late stages of anthrax disease when antibacterial methods normally are no ...

Invasive species harms native hardwoods by killing soil fungus

... one-tenth as fast in the infested soil. Seedlings grown in sterilized, AMF-free soil taken from invaded and pest-free locations showed similar reductions, suggesting that diminished microbial activity had suppressed tree growth. Other experiments showed that adding garlic mustard extracts to soil impaired...

New journal article urges use of animal serum-free media for growing live cells

...t at PCRM and lead author of the paper. Live cells grown in the laboratory are used for many purposes including the manufacture of drugs and diagnostic kits. Trends in Biotechnology, based in the United Kingdom, invited Mrs. Even to submit a paper after learning that she spearheaded the development of the...

Canine cancer vaccine program shows early promise

...accine is created from dog melanoma cells that are grown in the laboratory. The cells are treated so they can no longer divide and cause a tumor. DNA is then inserted into these cells, which directs the cells to secrete an immune stimulant. This combination of cells and immune stimulant, when administer...

H5N1 avian flu virus vaccine induces immune responses in healthy adults

...cluding vaccines made in cell cultures rather than grown in eggs. H5N1 avian influenza viruses are of enormous concern to public health officials worldwide. The potential for a human avian flu pandemic looms large, say experts, as daily reports indicate an increasing spread of infection in bird population...

Cellular scale drug delivery from the inside out
