High doses of vitamin D help tuberculosis patients recover more quickly

Posted: 03 Sep 2012 12:40 PM PDT

For decades before antibiotics became generally available, sunshine was used to treat tuberculosis, with patients often being sent to Swiss clinics to soak up the sun's healing rays. Now, for the first time scientists have shown how and why heliotherapy might, indeed, have made a difference. A new study has shown that high doses of Vitamin D, given in addition to antibiotic treatment, appear to help patients with tuberculosis recover more quickly.

Mass spectrometry makes the clinical grade

Posted: 03 Sep 2012 12:40 PM PDT

A new mass spectrometry-based test identifies proteins from blood with as much accuracy and sensitivity as the antibody-based tests used clinically, researchers report. The head-to-head comparison using blood samples from cancer patients measured biomarkers, proteins whose presence identifies a disease or condition. The technique should be able to speed up development of protein-specific diagnostic tests and treatment.

Mathematics or memory? Study charts collision course in brain

Posted: 03 Sep 2012 12:40 PM PDT

You already know it's hard to balance your checkbook while simultaneously reflecting on your past. Now, researchers -- having done the equivalent of wire-tapping a hard-to-reach region of the brain -- can tell us how this impasse arises.

Improved diagnosis of lung disease: New global benchmarks

Posted: 03 Sep 2012 11:31 AM PDT

New research has established the first global benchmarks for assessing lung function across the entire life span. The lung growth charts will help healthcare professionals better understand lung disease progression and help raise awareness of lung disease, which is the world's leading cause of death.

Parental problems prevent children taking much-needed asthma medication, study finds

Posted: 03 Sep 2012 11:31 AM PDT

Parental problems and a chaotic home environment could be preventing children from taking their prescribed asthma medication.

Marathon running could trigger pulmonary edema development in the lungs

Posted: 03 Sep 2012 11:31 AM PDT

A new study has found evidence that marathon running could trigger pulmonary edema, where fluid builds up in the lungs.

Intelligent self-repairing clothing and sensors will detect potential onset of an epileptic seizure

Posted: 03 Sep 2012 11:31 AM PDT

Intelligent self-repairing clothing and sensors that can detect the potential onset of an epileptic seizure sound like the stuff of science fiction but designers and engineers are turning them into reality.

Molecular signature of hantavirus infection in humans decoded

Posted: 03 Sep 2012 11:30 AM PDT

Scientists have succeeded in clarifying the molecular signature of the viruses that lead to an increasing size and number of hantavirus outbreaks in Germany.

Late motherhood: A selfish choice?

Posted: 03 Sep 2012 11:30 AM PDT

When women give birth in their late thirties or in their forties, it is not necessarily the result of a lifestyle choice – putting off motherhood for career reasons or from a desire to "have it all".  Nor should they be accused of selfishness or taking undue health risks.  

Newly identified stem cell population in skin's epidermis responsible for tissue repair

Posted: 03 Sep 2012 11:29 AM PDT

Researchers have identified a new stem cell population in the skin epidermis responsible for tissue repair. The skin, which is an essential barrier that protects our body against the external environment, undergoes constant turnover throughout life to replace dead cells that are constantly sloughed off from the skin surface. During adult life, the number of cells produced must exactly compensate the number of cells lost. Different theories have been proposed to explain how this delicate balance is achieved. In a new study, researchers demonstrate the existence of a new population of stem cells that give rise to progenitor cells that ensure the daily maintenance of the epidermis and demonstrate the major contribution of epidermal stem cells during wound healing.

Broader approach provides new insight into diabetes genes

Posted: 03 Sep 2012 11:29 AM PDT

Using a new method, diabetes researchers have been able to reveal more of the genetic complexity behind type 2 diabetes. The new research findings have been achieved as a result of access to human insulin-producing cells from deceased donors and by not only studying one gene variant, but many genes and how they influence the level of the gene in pancreatic islets and their effect on insulin secretion and glucose control of the donor.

A promising start for new anticancer drug

Posted: 03 Sep 2012 11:29 AM PDT

Spanish researchers have developed on a nanometric scale a new drug that combines photothermia and chemotherapy to help fight cancer.

High levels of DDT in breast milk in mothers living in malaria-stricken villages in South Africa

Posted: 03 Sep 2012 11:29 AM PDT

The highest levels ever of DDT in breast milk have been measured in mothers living in malaria-stricken villages in South Africa. The values lie well over the limits set by the World Health Organization. DDT has been used for many years in South Africa, sprayed indoors to fight malaria.

'Triple-threat' approach reduces life-threatening central line infections in children with cancer

Posted: 03 Sep 2012 09:36 AM PDT

Hospitals can dramatically reduce the number of life-threatening central line infections in pediatric cancer patients by following a set of basic precautions, by encouraging families to speak up when they observe noncompliance with the protocol and by honest analysis of the root cause behind every single infection, according to a new study.

Obesity and metabolic syndrome associated with impaired brain function in adolescents

Posted: 03 Sep 2012 09:36 AM PDT

A new study reveals for the first time that metabolic syndrome (MetS) is associated with cognitive and brain impairments in adolescents and calls for pediatricians to take this into account when considering the early treatment of childhood obesity.

Simple CT scan can predict worsening COPD, study suggests

Posted: 03 Sep 2012 09:36 AM PDT

The respective size of the pulmonary artery compared to the aorta, visible on a CT scan, is a strong predictor of the risk of exacerbation of chronic obstructive pulmonary disease, according to new research from UAB. The research team says that an increase in the size of the pulmonary artery relative to the size of the aorta is a valid indicator that a patient with COPD is at risk for exacerbating their disease. These exacerbations of COPD are associated with accelerated loss of lung function, worsened quality of life and increased risk of death.

Children taking steroids for asthma are slightly shorter than peers, study finds

Posted: 03 Sep 2012 09:36 AM PDT

Children who use inhaled steroid drugs for asthma end up slightly shorter at their full adult height than children who don't use the drugs, new results from a comprehensive asthma study show.

Coconut oil could combat tooth decay

Posted: 02 Sep 2012 07:24 PM PDT

Digested coconut oil is able to attack the bacteria that cause tooth decay. It is a natural antibiotic that could be incorporated into commercial dental care products, say scientists.
