Scientists identify genes responsible for 'black rot' disease in vegetables

...to belong to 13 different functional categories or related metabolic pathways. The researchers hope that the molecular characterization of these pathogenicity-related genes will lead to the development of a treatment for "black rot" disease. Employing whole-genome comparative genomic approaches, the authors...

Venom doc tracks down snake bioweapons

...ese toxin types, CRISP and kallikrein, are closely related to toxins called helothermine and gilatoxin, which are produced by the Beaded Lizard and the Gila Monster, respectively. One of the toxins in this study (called the waglerin peptide) did not exhibit any similarity to known proteins. Fry believes tha...

DOE JGI launches IMG public online microbial genome data clearinghouse

Innovative coating could give medical implants a longer life

...g peptoids -- synthetic molecules that are closely related to the natural proteins or peptides they mimic but don't degrade in the body. Messersmith and Barron wanted to use this durability of peptoids to the antifouling coating's advantage. They proceeded to intelligently design a new polymer made up of tw...

Atmosphere may cleanse itself better than previously thought

...reveal OH radical production from other chemically related molecules as well. "This study is important because it shows that the atmosphere could be generating far more OH radicals than we thought before because the models are underestimating the amount of chemistry that’s happening," said Sinha, who is an ...

Disabling gene defuses rheumatoid arthritis in mice

...prior studies his research team had conducted on a related gene, Foxj1. Both genes belong to the forkhead family of genes, which regulates the activity of other genes and has been connected to cancer and longevity. Last year Peng found that knocking out Foxj1 produced a lupus-like condition in mice. Foxj1 a...

Unlike other mammals, newborn dolphins and orcas stay active 24/7 during first months of development

... and facilitate rapid growth of brain and body and related behavioral development. "Somehow these seafaring mammals have found a way to cope with sleep deprivation, facilitating rather than hindering a crucial phase of development for their offspring," said Dr. Jerome Siegel, professor-in-residence at the S...

Aircraft Cabin Ventilation Influences The Transmission Of Diseases In-flight

...should educate the general public on health issues related to air travel and infection. They write that good hand hygiene has been proven to reduce the risk of disease transmission, and air travellers should make it part of their normal travel routine. Dr Gendreau comments: "Because of the increasing ease a...

Whole genome promoter mapping - Human Genome Project v2.0?

...e don't know how these genes are regulated or even related to each other. The identification of such a large number of promoters means that we can begin to answer these sorts of questions." ...

Mice brains shrink during winter, impairing some learning and memory

...ity there that have been associated with spatially related memory and learning performance. "We predicted that when you reduce the size of the hippocampus, it would have an impact on learning, and that's what we found," Nelson said. The shrinking of the brain corresponds to a season when the mice may have ...

Tamoxifen-like drug suggests new ways to selectively block estrogen

...hanges the way it interacts with a whole series of related downstream molecules. And those interactions explain why these drugs have different effects in different locations, such as breast, bone or uterus." This finding opens a new arena for drug design, suggests Greene. Nuclear receptors, such as the estr...

NCI Researchers Confirm the Effectiveness of Immunotherapy Approach to Treating Melanoma

...opment of infections in seven patients. Toxicities related to the chemotherapy and administration of a high dose of IL-2 were easily managed. The results of this study prove that a combination of chemotherapy and infusion of autologous, stimulated, white blood cells can have an impact on metastatic melanoma...

Major new UNC-based drinking water study suggests pregnancy fears may be overstated

...exposure to water purification byproducts might be related to bladder cancer, an issue not addressed in the present study. ...

Survey reveals women and doctors aren't talking about HPV

... communications gap between providers and patients related to cervical cancer and HPV is an issue that is largely due to time constraints, and a reluctance to discuss a sexually transmitted infection with women," said Dr. Beth Jordan, medical director at ARHP. "But because new techniques, including improved ...

Research on antibiotics receives historical recognition

... from actinomycetes, microbes in the soil that are related to bacteria and fungi. The culmination was the isolation of streptomycin in 1943 by Albert Schatz, a graduate student of Waksman's, using soil screening methods developed by Waksman. This deliberate search for chemotherapeutic agents contrasts with t...
