Liver cancer linked to cellular repair pathway

...motherapies for liver cancer, and many people with advanced liver disease are too ill for surgery to remove tumors," Sicklick said. "There is a desperate need for effective anticancer treatments that are safe for patients with liver disease." The results will be published in the April 4, 2006, issue of Carci...

Birth defects: 8 million annually worldwide

...fects in poorer countries, including more women of advanced age having children and a greater frequency of consanguineous (blood relative) marriages. In countries along the world's "malaria belt," a greater proportion of the population carries one copy of a gene for an inherited disease that confers some pro...

Researchers use 'trickery' to create immune response against melanoma

...by a combination of surgery and radiotherapy; more advanced cases are treated with radiotherapy and hormonal therapies such as the anti-androgens. In patients with metastatic disease where the cancer has spread to other parts of the body, a multi-disciplinary approach which could include chemotherapy is impli...

'Good' bacteria could save patients from infection infection by deadlier ones

...ding in Israel as well as the UK -- where the most advanced antibiotics and most rigorous antiseptic measures are taken. One must ask, says Spigelman, "why more of the same does not seem to be working?" The approach he suggests is that "we ought to begin treating the cause and not the consequence of this dise...

Eisai announces Phase II data on E7389, a potential new therapy for the treatment of breast cancer

...isease (SD). In treatment-refractory patients with advanced breast cancer this preliminary response rate (15%) appears promising. Based on the preliminary results of this study, the predominant serious side effect related to E7389 was neutropenia (low white blood cell counts). Other side effects were consi...

After extensive genetic analysis of fungal samples, the researchers suggest that mating between two less harmful fungal strains of the ...

Missing fossil link 'Dallasaurus' found

...inct some 65 million years ago," says Polcyn. The advanced fin-bearing mosasaurs have been grouped into three major lineages. Although a small number of primitive mosasaur have been known to retain land-capable limbs, they were thought to be an ancestral group separate from the later fin-bearing forms. Dalla...

Membrane research opens window to benefits for plants, humans

...he University of Illinois at Urbana-Champaign used advanced molecular dynamics simulations to study the mechanics of how such proteins respond to cellular signals such as altering pH (acidity and alkalinity) or phosphorylation, a common cellular chemical process that controls protein activity. Surprisingly, ...

Did feathered dinosaurs exist?

...today's winged creatures are derived directly from advanced theropods, or from an earlier shared ancestor. The current theory supports direct derivation, but recent fossil discoveries in China have led to new questions about the claim. The Chinese discoverers reported finding all stages of feather evolution a...
