Chromosome shattering, or 'chromothripsis,' has until now only been seen in animal cells.

Carotenoid levels in breast milk vary by country, diet Posted: 10 Jun 2015 01:17 PM PDT An analysis of breast milk concludes that levels of health-promoting compounds known as carotenoids differ by country, with the U.S. lagging behind China and Mexico, a reflection of regional dietary habits.

Fragile X proteins involved in proper neuron development Posted: 10 Jun 2015 01:17 PM PDT Fragile X syndrome is the most common inherited intellectual disability and the greatest single genetic contributor to autism. Unlocking the mechanisms behind fragile X could make important revelations about the brain. In a new study, researchers show that two proteins implicated in fragile X play a crucial role in the proper development of neurons in mice.

Survival benefit with 'fully human' EGFR antibody Necitumumab in squamous NSCLC Posted: 10 Jun 2015 12:24 PM PDT Results of a 1,093-person phase III clinical trial of the drug Necitumumab (IMC-11F8) combined with chemotherapies gemcitabine and cisplatin against stage IV squamous non-small cell lung cancer have been reported by researchers. With addition of necitumumab, median overall survival was 11.5 months compared with median survival of 9.9 months with the two chemotherapies alone.

Single protein causes Parkinson's disease and multiple system atrophy Posted: 10 Jun 2015 12:22 PM PDT Several neurodegenerative disorders are caused by aggregates of a single protein known as alpha-synuclein. Neurobiologists have discovered that the shape of these aggregates -- 'cylinders' or 'ribbons' -- determines whether a patient develops Parkinson's disease or multiple system atrophy, respectively.

Heart attack risk increases 16-21% with use of common antacid Posted: 10 Jun 2015 11:36 AM PDT Adults who use proton pump inhibitors are between 16 and 21 percent more likely to experience a heart attack than people who don't use the commonly prescribed antacid drugs, according to a massive new study.

Partial sleep deprivation linked to biological aging in older adults Posted: 10 Jun 2015 10:17 AM PDT One night of partial sleep deprivation promotes biological aging in older adults, a new study suggests. One night of partial sleep deprivation activates gene expression patterns in peripheral blood mononuclear cells (PBMCs) consistent with increasing accumulation of damage that initiates cell cycle arrest and increases susceptibility to senescence, the scientists report.

Statewide quality improvement program helps lower rates of trauma complications Posted: 10 Jun 2015 10:17 AM PDT A team of trauma surgeons has reported how data from a statewide quality collaborative helped them reduce the rate of a serious trauma complication by more than half. The researchers examined the rate of venous thromboembolism (VTE) events in trauma patients. VTEs include blood clots forming inside veins, also known as deep venous thrombosis (DVT).

New obesity treatment prevents bone loss during weight loss Posted: 10 Jun 2015 10:16 AM PDT Using the intestinal hormone GLP-1 in obesity treatment prevents the loss of bone mass otherwise frequently associated with major weight loss. According to the researchers behind the study, the results may have a significant bearing on future obesity treatment.

Youth on the autism spectrum overly sensitive to sensory stimuli have brains that react differently Posted: 10 Jun 2015 10:16 AM PDT Using functional magnetic resonance imaging, a team of researchers has shown for the first time that children with autism spectrum disorder who are overly sensitive to sensory stimuli have brains that react differently.

Interest in learning about skin cancer appears to increase during summer Posted: 10 Jun 2015 10:16 AM PDT Google searches for information on melanoma and skin cancer increased over the summer months during a five-year period, although the level of interest did not correlate with the melanoma mortality to incidence ratio, suggesting that increased search volumes may not be associated with early detection, according to research.

New drug can clear all psoriasis symptoms Posted: 10 Jun 2015 10:15 AM PDT A new psoriasis drug has resulted in 40 percent of people showing a complete clearance of psoriatic plaques after 12 weeks of treatment and over 90 percent showing improvement.

The researchers believe the finding could prompt an immediate review of the current standard of care for patients with certain so-called "superbug" infections.

Obesity linked to adrenal disorder in teens may increase risk for cardiovascular disease Posted: 10 Jun 2015 10:14 AM PDT Adolescents and young adults with congenital adrenal hyperplasia (CAH) have significantly increased amounts of abdominal fat tissue, placing them at greater risk for harmful conditions linked to obesity, including cardiovascular disease (CVD), researchers note.

Breast milk shared to help babies via online and offline communities Posted: 10 Jun 2015 08:15 AM PDT Sharing breast milk is thriving today and it appears high income, highly educated white women are some of the people to most often use the Internet to facilitate the exchange, a new study suggests. Another surprise out of the study: Cross-nursing (directly breastfeeding someone else's baby, often incorrectly referred to as wet-nursing, a professional service) seems to be a modern-day reality as well.

Fast-tracking precision medicine: Drug re-aimed to target diabetic kidney disease Posted: 10 Jun 2015 08:11 AM PDT It started out as a treatment for arthritis. But steered by science, it could become a first new approach in two decades for treating the damage that diabetes inflicts on the kidneys of millions of people, say researchers.

Teenagers should exercise like kids to achieve best health outcomes Posted: 10 Jun 2015 08:11 AM PDT As little as two minutes of high-intensity exercise four times a day improves health outcomes in adolescents, but the same amount of moderate-intensity exercise does not reap the same rewards, according to a new study.

Ultrasound screening for abdominal aortic aneurysms: Advantages for men, but not for women Posted: 10 Jun 2015 07:11 AM PDT Men benefit from one-time ultrasound screening for abdominal aortic aneurysms, a new review concludes. They live longer because a rupture of the abdominal aorta can be avoided. No such evidence is available for women, the researchers add.

Europe's most homophobic countries may be paving the way for a rise in HIV cases Posted: 10 Jun 2015 07:11 AM PDT Europe's most homophobic countries may be paving the way for a rise in HIV cases among gay and bisexual men, according to new research. The investigators found that in these countries, gay men knew less about HIV, were less likely to use condoms and are at greater potential risk of getting HIV when they do have sex.

Multimodality treatment for metastatic lung cancer with surgery may improve survival rates Posted: 10 Jun 2015 07:11 AM PDT Patients diagnosed with an advanced form of metastatic non-small cell lung cancer may benefit from surgical resection (removal of all or part of the lung) in combination with chemotherapy and radiation therapy, according to a new article.

Strong teeth: Nanostructures under stress make teeth crack resistant Posted: 10 Jun 2015 06:34 AM PDT Human teeth have to serve for a lifetime, despite being subjected to huge forces. But the high failure resistance of dentin in teeth is not fully understood. An interdisciplinary team of scientists has now analyzed the complex structure of dentin. They could reveal that the mineral particles are precompressed.

First-ever observation of the native capside of a retrovirus Posted: 10 Jun 2015 06:34 AM PDT For the first time ever, researchers have captured high-resolution images of the Bovine Leukemia Virus (BLV) capsid protein. Their images reveal unprecedented elements of flexibility in this protein, which are key for the assembly of the infectious particle. These findings represent a major progress in understanding retrovirus biology, opening new avenues towards the development of antiretroviral therapies.

Polycystic ovary syndrome: Lifestyle modification combined with metformin Posted: 10 Jun 2015 06:34 AM PDT Women who suffer from polycystic ovary syndrome could manage some of the symptoms by combining a change in lifestyle with taking the drug metformin, new research has found.

Pedophiles more likely to have physical irregularities Posted: 10 Jun 2015 06:32 AM PDT New research suggests pedophiles are more likely to have superficial facial flaws, known as Minor Physical Anomalies (MPAs). They are also more likely to be left-handed, says a researcher. She led an investigation into the prevalence and distribution of physical anomalies among men who are sent for sexological assessment. The study adds to a growing body of evidence that suggests pedophilia develops prenatally, around the same time that such physical flaws develop.

Bacterial protein serves as sensor Posted: 10 Jun 2015 06:32 AM PDT A method capable of precisely measuring the size of individual molecules has been developed by scientists. To do this, the researchers used the protein aerolysin from the bacterium Aeromonas hydrophila instead of the protein previously used for this purpose, alpha-hemolysin from the bacterium Staphylococcus aureus.

Increasing burden of non-communicable diseases Posted: 10 Jun 2015 06:32 AM PDT There is a great need to slow down the increasing number of people who die prematurely because of non-communicable diseases (NCDs) such as cardiovascular disease, diabetes and cancer. Although, the challenges vary between countries, which means each country has to set its priorities to reduce the risk of non-communicable diseases, according to a new dissertation.

How a faulty gene can trigger fatal heart condition Posted: 10 Jun 2015 06:31 AM PDT New research has revealed how a faulty gene can cause fatal abnormal heart rhythms that are brought on by exercise.

Plasma makes wounds heal quicker Posted: 10 Jun 2015 06:30 AM PDT Many people suffer from skin disorders. Open wounds are a particularly acute problem, especially among the elderly. PlasmaDerm, a new medical technology solution, uses plasma to facilitate faster healing of wounds.

New procedure to obtain induced pluripotent stem cells Posted: 10 Jun 2015 06:30 AM PDT For their ability to differentiate into other cell types, the embryonic stem cells hold a large potential in the medical industry. Their use, however, poses ethical questions due to the fact that in order to obtain them, it is necessary to destroy the embryo. For this reason, medical researches use the so-called induced pluripotent stem cells (iPSC).  In fact, it is possible to reprogram adult cells that can be obtained by simply drawing blood and making them "regress" to a similar state to that of embryonic stem cells, scientists say. The reprogrammed cells (iPSC) are capable of creating all the cell types of an adult organism, such as brain or heart cells.

Do newborns delivered by C-section face higher risk of chronic health problems later in life? Posted: 10 Jun 2015 06:28 AM PDT The evidence as to whether newborns delivered by C-section are more likely to develop chronic diseases later in life has been examined by investigators. The authors of a new study find that their evidence warrants concerns that C-section may lead to worse long-term child health.

New treatment hope for amyotrophic lateral sclerosis Posted: 10 Jun 2015 06:26 AM PDT A previously unknown link between the immune system and the death of motor neurons in amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, has been discovered by scientists.
