Outcome for acute lymphoblastic leukemia linked to gene expression patterns

... outcome. The study identified 123 previously unrecognized genes that are associated with resistance to cancer chemotherapy. Only three of these genes had been previously linked to drug resistance. These new genes represent potential targets for new agents that could be developed to overcome resistance to dr...

Ecologist calls for creation of an international panel to assess human behavior

...ity of this disciplinary organization has not gone unrecognized by social scientists,'' Ehrlich asserted, ''but there seems to be no real movement to correct the situation. Participation in an MAHB might help them sort themselves out.'' A member of the Stanford faculty since 1959, Ehrlich was named ESA's Eminent ...

Scientists learn how adjuvant makes vaccines effective

... most common adjuvant, alum, provokes a previously unrecognized group of immune-system cells to secrete the protein interleukin-4, which primes B cells for a better response to the vaccine. "Adjuvants have been included in vaccines given to hundreds of millions of people for decades," said Michael Jordan, M.D., ...

Mite transmits viruses damaging to wheat

...n lost this year. The cause in many cases will go unrecognized because what's left so closely resembles drought," Rush said. The damage has been done to many fields even with a rebound after spring rains and dry winter. Early in the season, even the wheat board warned harvest might fall to just over 50 perc...

Technique plucks rapidly evolving genes from a pathogen's genome

...r said. The researchers also discovered previously unrecognized genes that are evolving rapidly. These genes are attractive candidates for further research into which genes may be interacting with the human immune system. "We also found that within classes of antigens, some are under much stronger selection than ...

Chicken litter harbors agents that generate antibiotic multi-resistance, according to UGA study

...-gene-clustering systems are present in previously unrecognized reservoirs in companion animals and humans. The results will change our understanding of where resistance to new antibiotics will develop and how fast and how far it will spread and have implications for all antibiotic use, not just that in agricultu...

Researchers identify unifying code among diverse classes of natural antibiotics

...ure model enabled the identification of previously unrecognized antimicrobial peptides and peptide classes. "Our work builds upon the efforts of many excellent researchers in the field. We believe this discovery offers new insights into the evolution of immune defense against infection and drives new technolog...

Water hyacinths, popular ornamental plants, are readily available for purchase from catalogues and on-line. Native to the Amazon basin, they were ...

For some gorillas, local kin may mean local peace

...tic results point to a social structure previously unrecognized in gorillas and may help explain other unique characteristics of the western gorilla. Recent studies have reported that western gorillas exhibit frequent and often peaceful encounters between groups, behavior that differs significantly with that of t...

Possible link discovered between gene responsible for blood vessel development and ACD in newborns

... this study show that eNOS also plays a previously unrecognized role in lung development. "This is an exciting discovery as it is the first insight into the genetic basis of this human condition which is always fatal." St. Michael's Hospital worked with researchers at The Hospital for Sick Children on the link be...

RNA lariat may tie up loose ends to decades-old mystery of retrovirus life cycle

Purdue biologists expose the inner workings of viral machine

...he raw materials. The single strands, which can go unrecognized as a threat by the victim cell's defenses, spew out of the virus into the cytoplasm like pages off a printing press. "It is this single-stranded RNA that instructs the cell to begin manufacturing new viruses," Baker said. "Our research has essentiall...

NIH told regular and moderate exposure to sunlight is the key to preventing chronic disease

...iple sclerosis. Dr. Holick said, "We have a severe unrecognized epidemic of Vitamin D deficient patients on our hands. The public health issues at stake go far beyond bone health and involve chronic disease such as breast and colon cancer and high blood pressure. There is a mountain of well conducted, validated...

Sleep boosts ability to learn language, University of Chicago researchers find

Scientists: Cloak of human proteins gets HIV into cells

...roteins -- the Trojan horse -- provides previously unrecognized ways to escape the vaccine's effects, says Stephen Gould, Ph.D., professor of biological chemistry in the Institute for Basic Biomedical Sciences. To go from cell to cell, all retroviruses are packaged in "envelopes" made from viral proteins and prot...

In commenting on the work one of the participating investigators, Dr. Ray Monnat of the University of Washingt...

Researchers find new way to trigger self-destruction of certain cancer cells

...n's Research Hospital have discovered a previously unrecognized way that certain types of cancer cells can be forced to activate a self-destruction program called apoptosis. The finding suggests that drugs designed to activate apoptosis might be effective anti-cancer therapies. This strategy would target specific...
