NSAID drug protects against intestinal tumors in mice, despite poor diet and gene losses

...ize and number, but also pushed the cancer into an invasive state." Finally, they examined what happened when the knock-out mice were fed a Western diet enhanced with sulindac, an agent they had previously found help suppress tumor formation. To their surprise, none of the knock-out mice developed cancer. "...

Infants With Rare Genetic Disease Saved by Cord Blood Stem Cells

...ow must be harvested from living donors through an invasive surgical procedure. Finally, cord blood cells are less mature than adult bone marrow cells and thus do not need to perfectly match the patient's immune-related blood proteins, called antigens, said Kurtzberg. Only four of six cord blood "antigens" m...

Reservoirs may accelerate the spread of invasive aquatic species, researchers say

Biodiversity hotspots identify conservation priorities

...eats to the hotspots include: habitat destruction; invasive species; direct human exploitation of species for food, medicine, and the pet trade; and climate change, which magnifies the effects of habitat destruction and fragmentation. The latest analysis offers mixed news about existing hotspots. On one hand...

Antiretroviral therapy may prevent excess risk of some cancers in people with HIV

...in lymphoma, and, to a lesser extent, anal cancer, invasive cervical cancer, and Hodgkin lymphoma. However, less well understood are the associations of these cancer risks with the use of HAART, with immune status, and with behavioral risk factors such as smoking. To estimate excess cancer risk in people inf...

Research Using Mouse Models Reveals A Novel Key Player In The Initiation Of Colon Cancer

...omach. None of the tumors seen in either case were invasive leading to the conclusion that the Foxl1deficiency affects early stages in tumor formation. Additional analysis revealed that the Foxl1 deficiency affected the onset of tumor formation, accelerating them to arise in 1/3rd of the normal time. The auth...

Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

... tumor cells at their earliest stages, and without invasive chemical reagents. The technique generates a laser beam in single human cells pumped from a flask through tiny microchannels. The beam is altered by what it encounters. These changes, registered by an imaging spectrometer, instantly identify cancer-...

Researchers reveal the infectious impact of salmon farms on wild salmon

"We have worked out the spatial footprint ?the data are strong and show that the farms are having a significant impact over a very large area." The researchers isolated the effect of the salmon farm by studying the infection levels of migra...
