Physical function and sense of autonomy determine life-space mobility in older people

2014-04-09
(Press-News.org) Physical function and sense of autonomy are independent determinants of life-space mobility in older people. This was found in a study conducted at the Gerontology Research Center of the University of Jyväskylä. In this project, 848 older men and women that lived independently in the Jyväskylä region in Central Finland were interviewed at their own home.

Life-space mobility reflects a person's mobility with or without the use of a vehicle. Life-space mobility reflects an individual's opportunities to participate in the society. An individual's life-space may be restricted to one room, while going outdoors, into the town or beyond increases one's life-space and thus affects a person's quality of life.

Sense of autonomy is the perception of control over one's life. Physical limitations may restrict a person's possibilities to participate in activities outside of their own home when and how they want to. Other factors such as being a care giver or availability of transportation may also influence sense of autonomy, Postdoctoral Researcher Erja Portegijs explains.

Both physical function and sense of autonomy affect a person's behavior. This means that we may need to pay attention to psychosocial factors, in addition to physical function, when evaluating a person's mobility or life-space for example in the clinical setting, Portegijs states.

The results were published online in an international scientific Journal of the American Geriatrics Society on March 21, 2014.

Technical tests of biodiversity

2014-04-09
What happens when physicists play (using mathematical instruments) with the genetics of populations? They may discover unexpected connections between migration and biodiversity, for example, as recently done by a group of researchers from the International School for Advanced Studies (SISSA) in Trieste and the Polytechnic University in Turin in a study published in the journal Physical Review Letters. The effect of migration on biodiversity (intended as the coexistence of different genetic traits) is an open question: does migration increase or decrease the genetic variability ...

Embryonic development in animals – except mice and rats – remains largely unexplored. For a research project at the University of Zurich, the embryos of 134 species of animal were studied non-invasively for the first time using microcomputer imaging, thus yielding globally unique data. The embryos studied came from museum collections all over the world. The international ...

USA top in the world for entrepreneurship

2014-04-09
The USA is the most entrepreneurial economy in the world, according to the 2014 Global Entrepreneurship and Development Index (GEDI). (See Notes to Editors for the complete rankings.) The GEDI index combines data on entrepreneurial activities and aspirations with data describing how well the country supports entrepreneurial activity in the US and 119 other countries across the world. The USA came top, followed by Australia and Sweden in second and third place, respectively. The researchers found that the USA is a world leader when it comes to financing new businesses ...

Researchers say Neanderthals were no strangers to good parenting

2014-04-09
Archaeologists at the University of York are challenging the traditional view that Neanderthal childhood was difficult, short and dangerous. A research team from PALAEO (Centre for Human Palaeoecology and Evolutionary Origins) and the Department of Archaeology at York offer a new and distinctive perspective which suggests that Neanderthal children experienced strong emotional attachments with their immediate social group, used play to develop skills and played a significant role in their society. The traditional perception of the toughness of Neanderthal childhood is ...

Polysaccharides from Angelica sinensis alleviate oxidative damage to neurons

Polysaccharides from Angelica sinensis alleviate oxidative damage to neurons
2014-04-09
According to traditional Chinese medicine, the roles of Angelica sinensis correlate with tonifying the blood and promoting its circulation. Recent studies have shown that extracts of Angelica sinensis have antioxidative and neuroprotective effects. However, the anti-oxidative function of Angelica sinensis polysaccharide has rarely been addressed. In a preliminary experiment from Dr. Tao Lei and colleagues from Zhongnan Hospital of Wuhan University in China, Angelica sinensis polysaccharides not only protected PC12 neuronal cells from H2O2-induced cytotoxicity, but also ...

Stressful environments genetically affect African American boys

Stressful environments genetically affect African American boys
2014-04-09
PRINCETON, N.J.—Stressful upbringings can leave imprints on the genes of children as young as age 9, according to a study led by Princeton University and Pennsylvania State University researchers. Such chronic stress during youth leads to physiological weathering similar to aging. A study of 40 9-year-old black boys, published in the Proceedings of the National Academy of Sciences, shows that those who grow up in disadvantaged environments have shorter telomeres — DNA sequences that generally shrink with age — than their advantaged peers. The researchers also report ...

Unity is strength in the marketing of smallholder farm produce

2014-04-09
Smallholder farmers often face the challenge of accessing markets and selling their produce at competitive prices because they produce in small quantities that may not be commercially viable. The farmers are now being advised to adopt market interventions such as 'collective action' where they can come together as a group to pool their harvests and sell it in bulk. A study conducted by the World Agroforesty Centre (ICRAF) in Cameroon has shown that effective implementation of collective action improves market access for smallholder producers of agroforestry products ...

Is the increased risk of death due to alcohol intake greater for women or men?

Is the increased risk of death due to alcohol intake greater for women or men?
2014-04-09
New Rochelle, NY, April 9, 2014—The increased risk of death associated with alcohol intake is not the same for men and women. A study that compared the amount of alcohol consumed and death from all causes among nearly 2.5 million women and men showed that the differences between the sexes became greater as alcohol intake increased, as described in an article in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Women's Health website at http://www.liebertpub.com/jwh. In the article ...

Toward a faster, more accurate way to diagnose stroke

2014-04-09
When someone suffers from a stroke, a silent countdown begins. A fast diagnosis and treatment can mean the difference between life and death. So scientists are working on a new blood test that one day could rapidly confirm whether someone is having a stroke and what kind. Their report appears in the ACS journal Analytical Chemistry. Steven A. Soper and colleagues note that strokes, which are the third leading cause of death and disability in the United States, have two possible causes. In ischemic strokes, a clot stops blood flow in a part of the brain. In hemorrhagic ...

Tiny step edges, big step for surface science

Tiny step edges, big step for surface science
2014-04-09
This news release is available in French. It can be found in toothpaste, solar cells, and it is useful for chemical catalysts: titanium dioxide (TiO2) is an extremely versatile material. Alhough it is used for so many different applications, the behaviour of titanium oxide surfaces still surprises. Professor Ulrike Diebold and her team at the Vienna University of Technology managed to find out why oxygen atoms attach so well to tiny step edges at titanium oxide surfaces. Electrons accumulate precisely at these edges, allowing the oxygen atoms to connect more strongly. ...
