The grey seals in the Baltic Sea compete for fish with the fishing industry. The seals locally eat about the same quantities of cod, common whitefish, salmon, sea trout and eel as those taken by fishermen. This is the conclusion from research carried out at the University of Gothenburg, Sweden.
Competing with the fishing industry
On March 29, 2012, the National Science Foundation (NSF) conducted a bipartisan congressional briefing sponsored by the Coalition for National Science Funding and hosted by the Congressional Research and Development Caucus and its Co-Chairs Rush Holt (NJ-12) and Judy Biggert (IL-13) and special guests Representatives Daniel Lipinski (IL-3) and Sheila Jackson Lee (TX-18).
London -- The latest research developments to reprogram scar tissue resulting from myocardial infarction (MI) into viable heart muscle cells, were presented at the Frontiers in CardioVascular Biology (FCVB) 2012 meeting, held 30 March to 1 April at the South Kensington Campus of Imperial College in London.
CHICAGO — The antiangiogenic drug pazopanib has demonstrated clinically meaningful activity in patients with refractory urothelial cancer, according to results presented at the AACR Annual Meeting 2012, held here March 31 - April 4. The results also revealed that increases in interleukin-8 levels early after treatment with pazopanib may predict a lack of tumor response to the therapy.
CHICAGO - A pair of targeted therapies shrank tumors in some patients with treatment-resistant Ewing's sarcoma or desmoplastic small-round-cell tumors, according to research led by investigators from The University of Texas MD Anderson Cancer Center reported at the AACR Annual Meeting 2012.
Five of 17 Ewing's sarcoma patients responded to the combination, with two achieving complete responses, one for 27 weeks. The researchers noted that the ability to manage patients' treatment-related side effects is vital to maintaining the therapy and slowing disease progression.
A small study from Massachusetts General Hospital (MGH) researchers found that online virtual communities may be an effective way to train patients in meditation and other mind/body techniques. The ability to learn and practice approaches that elicit the relaxation response – a state of deep rest that has been shown to alleviate stress-related symptoms – in a virtual environment could help surmount several barriers that can restrict participation.
Amsterdam, NL -- Investigators from the University of Amsterdam, Netherlands, have shown that in most elderly patients invasive and expensive techniques, i.e. lumbar puncture and PET scan, are not useful to establish the diagnosis of Alzheimer's disease. They arrived at this conclusion after analysis of data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), a large collaborative research project of medical centers in the USA and Canada.
Asian Canadian teenagers who identify as lesbian, gay or bisexual are 30 times more likely to face harassment than their heterosexual peers – a factor that is linked to higher rates of alcohol or drug use, according to University of British Columbia research.
Recently published in the Canadian Journal of Community Mental Health, this is the first study in North America to investigate the links between Asian teens dealing with "dual minority discrimination," problem substance use and supports that can help reduce those risks.
Depression is more prevalent among stroke and transient ischemic attack survivors than in the general population, researchers reported in the American Heart Association's journal Stroke.
While most patients with stroke in the study had only mild disability, and only a fraction of those with TIAs had severe disability, depression rates were similar.
Creating a radioactive antibody fragment may allow scientists to identify fat and debris deposits in artery walls that are most likely to rupture and cause heart attacks, according to a new study in Circulation: Research, an American Heart Association journal.
Patients with inflammatory bowel disease (IBD) and other gastrointestinal (GI) disorders may be exposed to significant doses of diagnostic radiation, according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association.
INDIANAPOLIS — A study by Regenstrief Institute and U.S. Department of Veterans Affairs investigators provides the first in-depth look at how health care providers react to medication alerts generated by electronic medical record systems. The researchers plan to use this information to improve the design of medication alerts and diminish the phenomenon known as alert fatigue, where providers can become desensitized and may start unintentionally ignoring some important warnings.
WASHINGTON, DC -- A new analysis showing how the radical policies advocated by western economists helped to bankrupt Russia and other former Soviet countries after the Cold War has been released by researchers.
Authored by sociologists at the University of Cambridge and Harvard University, the study, which appears in the April issue of the American Sociological Review, is the first to trace a direct link between the mass privatization programs adopted by several former Soviet states, and the economic failure and corruption that followed.
Patients with irritable bowel syndrome (IBS) have a significantly greater prevalence of early adverse life events , including general trauma as well as physical, emotional and sexual abuse, according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association.
In recent years, with the growing concerns over environmental protection and human health, environment-friendly materials have received increasing attention, and for decades researchers have been fiercely studying lead-free piezoelectric materials with high piezoelectric properties.
