WASHINGTON, April 26, 2011 — The American Chemical Society (ACS) today released a new episode in its award-winning "Global Challenges/Chemistry Solutions" podcast series showcasing a discovery that could mean greener and more environmentally friendly production of a key ingredient used to make everything from paint to diapers.

Porto Alegre, Brazil- Tumor progression is usually ensured by more than one proliferative mechanism. When one of these is shut down by a specifically targeted drug, other mechanisms may emerge. While these events may lead to treatment failure, they may also become an opportunity for researchers to identify novel targets to be further explored. In a paper recently published in the journal Oncology ("BDNF/TrkB content and interaction with gastrin-releasing peptide receptor blockade in colorectal cancer," Vol.
Cholesterol-lowering drugs known as statins may help clot-busting drugs treat strokes, according to researchers at Washington University School of Medicine in St. Louis.
The research involved 31 patients with ischemic stroke, a disorder when a clot blocks blood flow to part of the brain. In 12 patients who were already taking statins to control their cholesterol, blood flow returned to the blocked areas of the brain more completely and quickly.
Planes were grounded all over Europe when the Eyjafjallajökull volcano erupted in Iceland last year. But no one knew if the no fly zone was really necessary. And the only way to find out would have been to fly a plane through the ash cloud - a potentially fatal experiment.Now a team of researchers from the University of Copenhagen and the University of Iceland have developed a protocol for rapidly providing air traffic authorities with the data they need for deciding whether or not to ground planes next time ash threatens airspace safety.
BOSTON (April 26, 2011) —Human papillomavirus (HPV) causes cervical cancer, the second most common cause of cancer death for women, and is a common cause of anogenital and some head and neck cancers. Thanks to research being done at Tufts University School of Medicine, patients infected with cancer-causing HPV may someday have an alternative to surgical and harsh chemical treatments.
Water molecules surround the genetic material DNA in a very specific way. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have discovered that, on the one hand, the texture of this hydration shell depends on the water content and, on the other hand, actually influences the structure of the genetic substance itself. These findings are not only important in understanding the biological function of DNA; they could also be used for the construction of new DNA-based materials.
NORTHRIDGE, CA (April 26, 2011) — Folic acid, an essential vitamin formulated to be part of a multivitamin + DHA liquid softgel capsule, is absorbed and available within the body in amounts similar to folic acid formulated for solid tablets, according to a study presented in a late breaking session at the Experimental Biology (EB) 2011 annual meeting.
A motor regulatory protein can block human ovarian tumor growth, leading to eventual cancer cell death and possible new therapies to treat the disease, according to Penn State College of Medicine researchers.
Among U.S. women, an estimated 21,880 new cases and 13,850 deaths occurred in 2010 from epithelial ovarian cancer, one of the most common forms of ovarian cancer and the most lethal gynecologic cancer in women.
On April 26, 1986, history's greatest nuclear accident took place northwest of the Ukrainian city of Chernobyl. Despite the scale of the disaster, 25 years later, we still do not know its real effects. An international team of investigators has shown for the first time that the colour of birds' plumage may make them more vulnerable to radioactivity.
Radiation causes oxidative stress, damages biological molecules and may have "important" negative effects on organisms in relatively high doses, like those found in certain zones close to Chernobyl.
While incidents of melanoma continue to increase despite the use of sunscreen and skin screenings, a topical compound called ISC-4 may prevent melanoma lesion formation, according to Penn State College of Medicine researchers.
"The steady increase in melanoma incidence suggests that additional preventive approaches are needed to complement these existing strategies," said Gavin Robertson, Ph.D., professor of pharmacology, pathology, dermatology and surgery, and director of Penn State Hershey Melanoma Center.
Minority races—especially Blacks—are more willing than Whites to expend personal financial resources to prolong life after being diagnosed with lung or colorectal cancer, even if it means using up all of their personal financial resources. That is the conclusion of a new study published early online in Cancer, a peer-reviewed journal of the American Cancer Society. Delivering quality cancer care that is in accordance with patients' wishes requires a better understanding of the reasons for these differences in preference.
BLOOMINGTON, Ind. -- Indiana University scientists have found chemical flame retardants in the blood of pet dogs at concentrations five to 10 times higher than in humans, but lower than levels found in a previous study of cats.
Their study, "Flame Retardants in the Serum of Pet Dogs and in their Food," appears this month in the journal Environmental Science & Technology. Authors are Marta Venier, an assistant research scientist in the School of Public and Environmental Affairs, and Ronald Hites, a Distinguished Professor in SPEA.
BIRMINGHAM, Ala. – People in minority groups, especially black Americans, are more willing than their white counterparts to exhaust their personal financial resources to prolong life after being diagnosed with lung or colorectal cancer, according to a University of Alabama at Birmingham study published April 26, 2011, online in Cancer, the journal of the American Cancer Society.
DALLAS – April 26, 2011 – A clinical trial has sifted out the most effective single-drug chemotherapy regimen for quick-growing but highly curable cancers that arise from the placentas of pregnant women.
In the comparison trial for treating low-risk gestational trophoblastic neoplasia (GTN), researchers found that a biweekly dose of dactinomycin had a higher complete response rate than a weekly dose of methotrexate, the more commonly used drug. GTN is a group of rare tumors that involve abnormal growth of cells inside a woman's uterus.
LEXINGTON, Ky. (April 26, 2011) – A study performed by University of Kentucky researchers shows promise for the use of azithromycin in treating Ureaplasma-colonized or infected premature infants to prevent bronchopulmonary dysplasia (BPD).
The study, published in Pediatric Pulmonology, showed subjects colonized or infected with the Ureaplasma bacteria developed BPD or died 73 percent of the time in the azithromycin-treated group, compared to 94 percent of the time in the placebo group.
