Ecological destruction fuels emerging diseases

...he decline of global biodiversity is linked to the emergence of new human and wildlife diseases such as West Nile Virus and avian flu. "The biodiversity crisis is not just about extinctions," says Dr. Brooks, whose pioneering parasite systematics research is supported by Science and Engineering Research Canad...

Scientists find missing enzyme for tuberculosis iron scavenging pathway

...e morbidity in humans than any other bacteria. The emergence of multi-drug resistant strains of M. tuberculosis has prompted the search for new drug targets and a better understanding of the mechanism of resistance in this bacterium. Several spans of DNA in the M. tuberculosis genome have been annotated as an...

Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance

...o understand the importance of genetic factors for emergence and treatment of various diseases. The agreement enables us to perform these studies at an acceptable cost and we will also get access to new technology at an early stage. Our expectation is that this cooperation will help us to improve peoples healt...

A new study examines how shared pathogens affect host populations

...ies transmission is often associated with pathogen emergence and therefore has been considered as a negative factor for humans, wildlife, and species of agricultural importance. Many pathogens like malaria, Lyme disease or West Nile encephalitis that infect multiple hosts are commonly transmitted by vectors, a...

Emergence of cancer as major cause of childhood death in developing countries is not being adequately addressed

The emergence of cancer as a major cause of death among children in developing regions of the world is not being adequately addressed by national or international health organizations and charities, according to investigators at St. Jude Children’s Research Hospit...

Supercomputers to focus brains on AIDS dilemma

...tors that had proven so effective until the recent emergence of drug-resistant mutants. The new drug possibilities flow out of a long series of molecular dynamics simulations by McCammon's group. These simulations have focused on the catalytic domain of HIV-1 integrase, and relied on the large-scale computati...

Oldest cranial, dental and postcranial fossils of early modern European humans confirmed

...semblage is central to discussions of modern human emergence in Europe and the fate of the Neandertals. The Mladc remains are universally accepted as those of early modern humans. However, there has been an ongoing debate as to whether they also exhibit distinctive archaic features, indicative of some degree ...

Ebola virus: from wildlife to dogs

...s which, starting from this reservoir, lead to the emergence of human epidemics. Knowledge of the reservoir animal and of the virus's natural cycle should assist in devising suitable prevention strategies against Ebola epidemics. ### Marie Guillaume - DIC (1) This research, conducted since 2001, involves a ...

Fungus Effective Against Winged Termites

...celebrating. But for many in the South, the annual emergence of fertile, winged termites swarming furiously to scatter and search for mates isn't one of them. In New Orleans, as the swirling, airborne masses of termites become more conspicuous, researchers with the Agricultural Research Service (ARS) are busy...

Tamoxifen-like drug suggests new ways to selectively block estrogen

... of Duke, findings such as this should lead to the emergence of "a new wave of estrogen receptor modulators with improved specificity. We are moving, he said, "very close to the day where a proteomic profile of a tumor will determine the best SERM or SERD or other endocrine therapy that will yield maximal bene...

Antiretroviral Therapy May Prevent HIV Transmission From Breastfeeding Mothers To Infants

... rash, neutropenia, and anemia, and to lead to the emergence of drug-resistant virus. For the second study, the researchers examined the ability of combination antiretroviral therapy to reduce HIV-1 RNA and DNA levels in breast milk. They measured these levels in two groups: 26 women who received nevirapine, ...

Map of life on Earth could be used on Mars

...ergence, facilitated by lateral gene transfer. The emergence of traits corresponding to measurable changes in the known geologic record allow researchers to date organisms with relative certainty. Blank can then use chronological data to analyze niche specialization, "where these organisms like to grow," among...

UN: World in big ecological mess

Enlisting genomics to understand flu evolution

...g to an epidemiologically significant outcome--the emergence of the "Fujian" strain in the 2003-2004 flu season. The Institute for Genomic Research, with funding from the National Institute for Allergy and Infectious Diseases, sequenced the genomes of the collected flu viruses. Examining these sequences, Holm...

Multi-species genome comparison sheds new light on evolutionary processes, cancer mutations

...or mammals, spurring their diversification and the emergence of new mammalian orders. This situation would have facilitated opportunities for the isolation of mammals into more distinct breeding groups, speeding the development of species-specific chromosomes. "This study has revealed many hidden secrets on t...

Agricultural antibiotic use contributes to 'super-bugs' in humans

...biotic prescribing in hospitals contributes to the emergence of drug resistant bacteria. But for some antibiotics, an even more important factor contributing to such emergence, argues a team of researchers in the open access international medical journal PLoS Medicine, is the use of antibiotics in agriculture....
