How blood vessels regroup after stroke

11/02/2013 | CIENCIA ON LINE
Scientists have simulated "robot" cells to study the development of the microvascular systems in the brain. The goal is to find a way to direct the development of vessels that feed oxygen-starved cells in stroke and neurodegenerative disease patients. Fuente :...

Community health workers help type 2 diabetes care

11/02/2013 | CIENCIA ON LINE
Researchers who conducted a clinical trial in American Samoa to test whether community health workers could help adults with type 2 diabetes found that the patients who received the intervention were twice as likely to make a clinically meaningful improvement as those who remained with care only...

Can simple measures of labile soil organic matter predict corn performance?

11/02/2013 | CIENCIA ON LINE
Researchers are characterizing simple, cheap measurements of labile soil organic matter that could predict the performance of corn crops and help farmers optimize their cropping systems. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/H...

Exercise linked with reduced prostate cancer risk in Caucasians but not African-Americans

11/02/2013 | CIENCIA ON LINE
A new study suggests that exercise may reduce Caucasian men's risk of developing prostate cancer. And among Caucasian men who do have prostate cancer, exercise may reduce their risk of having more serious forms of the disease. Unfortunately, the benefits do not seem to apply to African-American...

High blood pressure during pregnancy may signal later heart disease risk

11/02/2013 | CIENCIA ON LINE
High blood pressure during pregnancy — even once or twice during routine medical care — can signal substantially higher risks of heart and kidney disease and diabetes, according to new research. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/_...

Tumor blood vessels prevent the spread of cancer cells

11/02/2013 | CIENCIA ON LINE
A lack of the protein endoglin in the blood vessels of tumor-bearing mice enables the spread of daughter tumours, according to researchers. Given that the tumor vasculature constitutes an important barrier to the spread of cancer cells, the team suggests that drugs should be developed to...

Protein 'filmed' while unfolding at atomic resolution

11/02/2013 | CIENCIA ON LINE
Whether Alzheimer’s, Parkinson’s or Huntington’s Chorea – all three diseases have one thing in common: They are caused by misfolded proteins that form insoluble clumps in the brains of affected patients and, finally, destroy their nerve cells. One of the most important questions in the biological...

Birds evolved ultraviolet vision several times

11/02/2013 | CIENCIA ON LINE
Ultraviolet vision evolved at least eight times in birds from a common violet sensitive ancestor finds a new study. All of these are due to single nucleotide changes in the DNA. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/I...

Dogs may understand human point of view

11/02/2013 | CIENCIA ON LINE
Domestic dogs are much more likely to steal food when they think nobody can see them, suggesting for the first time that dogs are capable of understanding a human’s point of view. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/8...

Therapeutic effect of RNAi gene silencing effective in cancer treatment, study suggests

11/02/2013 | CIENCIA ON LINE
A new study shows for the first time that ribonucleic acid interference (RNAi) is effective in the treatment of cancer patients. Harnessing these molecules to silence genes involved in the development and growth of cancer cells is an important step forward in developing a new and more targeted...

When it comes to love, men are the biggest risk takers

11/02/2013 | CIENCIA ON LINE
How far would you go to get the attention of the one you love? According to a recent study it seems that given a romantic opportunity, men are willing to take big risks in getting attention from the opposite sex, and what’s more it’s all down to evolution. Fuente :...

Stem cell breakthrough could lead to new bone repair therapies on nanoscale surfaces

11/02/2013 | CIENCIA ON LINE
Scientists have created a new method to generate bone cells which could lead to revolutionary bone repair therapies for people with bone fractures or those who need hip replacement surgery due to osteoporosis and osteoarthritis The researchers cultured human embryonic stem cells on to the surface...

Nanotechnology against pollen allergy

11/02/2013 | CIENCIA ON LINE
Scientists have now been able to identify the grass pollen molecule, against which the allergic response of hay fever in children is initiated. In addition, it was shown that the first individual antibodies generated in children against individual pollen molecules can be identified even before...

La Nebulosa Esquimal en rayos X

11/02/2013 | CIENCIA ON LINE
El observatorio espacial XMM-Newton nos permite mirar en el interior de la capucha peluda de la Nebulosa Esquimal, desvelando una cálida cara de gas a 2 millones de grados centígrados. Fuente : http://www.esa.int/ESA_in_your_country/Spain/La_Ne...

CWRU study suggests interacting with avatars may reduce depressive symptoms in young adults

11/02/2013 | CIENCIA ON LINE
A new preliminary study by researchers at Case Western Reserve University suggests that depression symptoms may be significantly reduced when 18- to 25-year-olds interact with computerized avatars -- virtual 3D images of a healthcare provider like a nurse practitioner or physician -- as a way to...

Courts mostly ignore immigration status in lawsuits, study says

11/02/2013 | CIENCIA ON LINE
Most courts disregard the immigration status of workers who file suit against former employers, says a study from Michael LeRoy, a professor of law and of labor and employment relations at Illinois. Fuente : http://www.eurekalert.org/pub_releases/2013-02/uoi...

New details on the molecular machinery of cancer

11/02/2013 | CIENCIA ON LINE
New details into the activation of a cell surface protein that has been strongly linked to a large number of cancers and is a major target of cancer therapies have been reported by Berkeley Lab researchers. Fuente : http://www.eurekalert.org/pub_releases/2013-02/dbn...

Deep genomic analysis identifies a micro RNA opponent for ovarian cancer

11/02/2013 | CIENCIA ON LINE
Researchers employed an extensive analysis of genomic information to identify a new, high-risk cohort of ovarian cancer patients, characterize their tumors, find a potential treatment and test it in mouse models of the disease. Fuente : http://www.eurekalert.org/pub_releases/2013-02/uot...

Geoscience Currents #69: US female geoscience enrollment and degree rate is mixed in 2011-2012

11/02/2013 | CIENCIA ON LINE
Geoscience Currents #69 explores how female geoscience enrollments and degrees changed in the 2011-2012 academic year. New data collected shows that female geoscience enrollments and degrees in the US dropped sharply at both the Bachelor's and Master's levels, but increased slightly at the Doctoral...
