Improved prognosis for esophageal cancer

2011-05-26
(Press-News.org) In recent years, the number of cases of adenocarcinoma of the esophagus (or gullet) has been on the rise. At the same time, however, new ways of treatment are improving the outlook for patients. In the current issue of Deutsches Ärzteblatt International (Dtsch Artzebl Int 2011; 108[18]: 313𔃇), Angelika Behrens and her working group report on innovations in diagnosis and treatment.

The main cause of this cancer is reflux of gastric acid from the stomach, with heartburn as the main symptom. Other risk factors are being male, being overweight, and having relatives with this disease. Today we are able to discover and treat adenocarcinoma (Barrett's carcinoma) at an early stage. This has chiefly been made possible by the introduction of high-definition videoendoscopy and endosonography (endoscopic ultrasound). Locally restricted tumors can be resected endoscopically. For locally advanced Barrett's carcinoma, the standard treatment is surgery combined with chemotherapy. For esophageal cancer that has already metastasized, there are new approaches to therapy based at the molecular level. So-called molecular targeting uses antibodies or small molecules to alter signal transduction directly inside the tumor cell and thus inhibit growth. The authors also report on their experience of treating over 1000 patients with this cancer.

New bandwidth management techniques boost operating efficiency in multi-core chips

2011-05-26
Researchers from North Carolina State University have developed two new techniques to help maximize the performance of multi-core computer chips by allowing them to retrieve data more efficiently, which boosts chip performance by 10 to 40 percent. To do this, the new techniques allow multi-core chips to deal with two things more efficiently: allocating bandwidth and "prefetching" data. Multi-core chips are supposed to make our computers run faster. Each core on a chip is its own central processing unit, or computer brain. However, there are things that can slow these ...

Global warming may affect the capacity of trees to store carbon, MBL study finds

Global warming may affect the capacity of trees to store carbon,  MBL study finds
2011-05-26
MBL, WOODS HOLE, MASS.—One helpful action anyone can take in response to global warming is to plant trees and preserve forests. Trees and plants capture carbon dioxide during photosynthesis, thereby removing the most abundant greenhouse gas from the atmosphere and storing some of it in their woody tissue. Yet global warming may affect the capacity of trees to store carbon by altering forest nitrogen cycling, concludes a study led by Jerry Melillo, Distinguished Scientist at the Marine Biological Laboratory (MBL) Ecosystems Center, and published this week in Proceedings ...

New Canadian blood pressure education program a powerful tool in fight to reduce stroke

2011-05-26
(Toronto, May 25, 2011): High blood pressure – the silent killer – is taking a hit from a new, ground-breaking treatment program from the Heart and Stroke Foundation of Ontario. Last Sunday, in New York City, Dr. Sheldon Tobe, Chair of the Canadian Hypertension Education Program (CHEP) and a long-standing Heart and Stroke Foundation researcher, unveiled a new and powerful tool in the management of hypertension at the American Society of Hypertension (ASH) Scientific Meeting —The Heart&Stroke Hypertension Management Program. "Diagnosing high blood pressure (hypertension) ...

2020 vision of vaccines for malaria, TB and HIV/AIDS

2011-05-26
SEATTLE, WA, May 25, 2011 – Collectively, malaria, TB & HIV/AIDS cause more than five million deaths per year – nearly the entire population of the state of Washington – and represent one of the world's major public health challenges as we move into the second decade of the 21st century. In the May 26, 2011, edition of the premier scientific journal Nature, Seattle BioMed Director Alan Aderem, Ph.D., along with Rino Rappuoli, Ph.D., Global Head of Vaccines Research for Novartis Vaccines & Diagnostics, discuss recent advances in vaccine development, along with new tools ...

Can we get there from here? Translating stem cell research into therapies

2011-05-26
A new article published by Cell Press in the May 26 issue of the journal Neuron provides comprehensive insight into the current status of neural stem cell research and the sometimes labyrinthine pathways leading to stem cell-based therapies. The perspective on translating neural stem cell research into clinical therapeutics is part of a special issue of Neuron devoted to neural stem cells and neurogenesis and is published in collaboration with the May issue of Cell Stem Cell, which also has a selection of reviews on this topic. Neurological disease and injury are a major ...

Endangered gourmet sea snail could be doomed by increasing ocean acidity

2011-05-26
Increasing levels of ocean acidity could spell doom for British Columbia's already beleaguered northern abalone, according to the first study to provide direct experimental evidence that changing sea water chemistry is negatively affecting an endangered species. The northern abalone--prized as a gourmet delicacy--has a range that extents along the North American west coast from Baja California to Alaska. Even though British Columbia's northern abalone commercial fisheries where closed in 1990 to protect dwindling populations, the species has continued to struggle, largely ...

Japan earthquake appears to increase quake risk elsewhere in the country

2011-05-26
Japan's recent magnitude 9.0 earthquake, which triggered a devastating tsunami, relieved stress along part of the quake fault but also has contributed to the build up of stress in other areas, putting some of the country at risk for up to years of sizeable aftershocks and perhaps new main shocks, scientists say. After studying data from Japan's extensive seismic network, researchers from the Woods Hole Oceanographic Institution (WHOI), Kyoto University and the U.S. Geological Survey (USGS) have identified several areas at risk from the quake, Japan's largest ever, which ...

Syracuse University scientists discover new hitch to link nerve cell motors to their cargo

2011-05-26
With every bodily movement—from the blink of an eye to running a marathon—nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers (neurotransmitters) that excite muscles cells into action. It's a complex process, which scientists are still trying to understand. A new study by Syracuse University researchers has uncovered an important piece of the puzzle. The study, published in the April 22 issue of the Journal of Biological Chemistry (JBC), describes the discovery of a protein that is involved ...

Rethinking extinction

Rethinking extinction
2011-05-26
For more than 40 years, the International Union for Conservation of Nature (IUCN) has published the Red List of Threatened Species describing the conservation status of various species of animals. They are now also including plants in their lists and the picture they present is dramatic. According to recent estimates, around 20 per cent of flowering plants are currently at risk of extinction – though the exact number is unknown since such a small proportion of plant species has even been measured. Now, however, research conducted in South Africa and the U.K. by an international ...

Study shows elderly drivers support competency tests

2011-05-26
AURORA, Colo. (May 25, 2011) – Researchers studying driving habits and accident rates among the elderly found a majority surveyed supported mandatory retesting of drivers based on age while saying they would hand over the keys if a doctor or loved one said they were no longer fit to drive. "We are now exploring the idea of an advance directive for driving where someone would be designated to take away your keys at some point," said Emmy Betz, MD, MPH, at the University of Colorado School of Medicine who led the study and presented it in May before the American Society ...
