A Leicester cancer research project, which receives funding from Hope Against Cancer (formerly The Hope Foundation,) is investigating whether an extract from bilberries can prevent or delay the onset of certain cancers.
Since it first appeared in Hong Kong in 1997, the H5N1 avian flu virus has been slowly evolving into a pathogen better equipped to infect humans. The final form of the virus, biomedical researchers fear, will be a highly pathogenic strain of influenza that spreads easily among humans.
Researchers at the Agency for Science, Technology and Research’s (A*STAR) Institute of Molecular and Cell Biology (IMCB) have discovered new molecular mechanisms that provide a more detailed understanding of how the normally benign Dr. Jekyll-like fungus known as Candida albicans transforms into a serious and often life-threatening Mr. Hyde-like form.
Researchers have uncovered new evidence in mice that may explain how emotionally charged situations can leave such a powerful mark on our memories. Surges of the stress hormone norepinephrine (also known as noradrenaline) that often accompany strong emotions spark a series of molecular events that ultimately strengthen the connections between neurons, the team reports in the Oct. 5, 2007, issue of the journal Cell, a publication of Cell Press.
Nurses are now playing a valuable role in assessing people held in police custody, complementing the traditional role of the police doctor and improving response times, according to research published in the latest Journal of Advanced Nursing.
The benefits of applying technological know how to patient care were demonstrated by Prime Minister Gordon Brown at Imperial College London yesterday.
Both extensive psychological research and personal experiences confirm that events that happen during heightened states of emotion such as fear, anger and joy are far more memorable than less dramatic occurrences. In a report this week in Cell, Johns Hopkins researchers and their collaborators at Cold Spring Harbor and New York University have identified the likely biological basis for this: a hormone released during emotional arousal “primes” nerve cells to remember events by increasing their chemical sensitivity at sites where nerves rewire to form new memory circuits.
American children are drinking too little milk and what they are consuming is too high in fat, according to a Penn State study. “There is a strong correlation between dairy consumption and calcium,” says Sibylle Kranz, assistant professor of nutritional sciences. “While there is calcium in fortified orange juice, for example, it is not as bioavailable as that found in milk.” She notes that people need to take calcium with vitamin D and some protein for optimal use in the body.
The Hartford Center for Geriatric Nursing Excellence in the University of Iowa College of Nursing, and two other Hartford centers in the nation, have been funded for a four-year $1.2 million grant to ensure that nurses have the most recent evidence-based guidelines for caring for elders with mental health issues.
Prior research has shown that exposure to business-related objects makes people act more competitively, even though they do not realize it. A fascinating new study by researchers at Stanford extends this research by investigating how different consumers are affected by the same stimuli. The study reveals significant differences between the way men and women subconsciously react after exposure to certain objects.
