Short sleep linked to distracted secondary eating, drinking Posted: 11 Dec 2015 12:41 PM PST Research suggests a link between short sleep and obesity from secondary eating and drinking while engaged in another activity. Investigators assessed time spent on secondary eating and drinking as well as primary eating and drinking, with sleep duration as the principal independent variable.

Violence in Mexico affected children's mental health Posted: 11 Dec 2015 11:51 AM PST Children who lived in Juarez, Mexico -- once dubbed the murder capital of the world -- in 2010 have high levels of behavioral and emotional problems, according to new research.

Potential of liquid biopsy for breast cancer patients Posted: 11 Dec 2015 11:50 AM PST Information gleaned from a liquid biopsy may help predict how individual women with advanced breast cancer will respond to certain therapies as well as reveal genetic mutations that can impact prognosis, according to two new studies.

Intensive training affects the sleep, performance and mood of athletes, but more carbs may help Posted: 11 Dec 2015 10:17 AM PST Getting enough sleep is an essential part of any athlete's training program, but a new study reveals intensive bouts of exercise can make it hard to get 40 winks. Suspecting that intense exercise can lead to sleep disturbance, scientists studied the effects of two nine day periods of heavy training on 13 highly trained cyclists. The researchers monitored the athletes' moods, sleep patterns and performance before, during and after exercise.

Health labels influence flavor perception Posted: 11 Dec 2015 10:15 AM PST Researchers found that food labels influence the perception of flavor. Light products are considered less tasty. Researchers at a flavor lab organized a flavor experiment with young Gouda cheese for a test audience of 129 people. Without knowing it, the participants tasted the same cheese several times, but each time with a different label, such as 'light' or 'reduced salt'.

Possibility to Completely Restore Human Bones Posted: 11 Dec 2015 10:15 AM PST Biomedical startup company Biom? is offering a synthetic bone equivalent used for bone restoration operations in odontology. The bone equivalent Cell'in is made from cellulose/hydroxyapatite composite. The analogical products in global market are usually created on the basis of synthetic polymers.

Neural stimulation offers treatment for 'dry eye' Posted: 11 Dec 2015 10:06 AM PST Scientists have developed a device that electronically stimulates tear production, which will offer hope to sufferers of dry eye syndrome, one of the most common eye diseases in the world.

Review explores cancer screening, prevention, and treatment in people with mental illness Posted: 11 Dec 2015 09:44 AM PST A new report suggests that healthcare system and societal factors are just as critical as individual lifestyle factors in creating health disparities among people with metal illness.

Aural feedback for oral hygiene Posted: 11 Dec 2015 09:44 AM PST Researchers in Japan have discovered that how effectively we clean our teeth and how satisfied we are with the brushing job we do depends a lot on the sound of the bristles scrubbing against the enamel. They have described details of a futuristic toothbrush that might help with oral hygiene.

T-DM1 improved overall survival for heavily pretreated patients with HER2-pos breast cancer Posted: 11 Dec 2015 09:43 AM PST Among patients with HER2-positive, metastatic breast cancer that had progressed despite treatment with two or more forms of HER2-targeted therapy (trastuzumab [Herceptin] and lapatinib [Tykerb]), median overall survival was increased for those treated with trastuzumab emtansine (T-DM1 [Kadcyla]) compared with those who received treatment of physician's choice, according to results from the phase III TH3RESA clinical trial.

Earlier intervention leads to better weight recovery in children with multiple risk factors for weight faltering Posted: 11 Dec 2015 09:43 AM PST Young children who are underweight experienced greater weight recovery the earlier an intervention was started, and the recovery was more significant in children with multiple household risk factors, according to a study.

Using public surveillance to study insect vectors of Chagas disease in Texas Posted: 10 Dec 2015 11:47 AM PST Chagas disease is caused by a parasitic protozoan (Trypanosoma cruzi) and transmitted via triatomine insects known locally in Texas as 'kissing bugs.' Due to the success of community based triatomine surveillance and collection in Central and South America, researchers set up a citizen science program to gain insight into the distribution and infection prevalence of triatomine insects in Texas.

Researchers identify gene possibly linked with methamphetamine addiction Posted: 10 Dec 2015 11:47 AM PST A new study sheds light on the significance of a potential genetic risk factor for drug addiction and possibly other neuropsychiatric disorders. Both genetic and environmental factors are known to influence susceptibility to substance use disorders. However, the genetic basis of these disorders is largely unknown.

New aspect of gene regulation, possible target for cancer drugs discovered Posted: 10 Dec 2015 11:47 AM PST The expression of about three-quarters of active genes in a cell is controlled by a process in which the DNA-transcribing enzyme hesitates before going to work. Experiments have identified the complex of proteins that helps restart this enzyme when it stalls, and so helped to explain how some promising cancer drugs work.

Safe, inexpensive chemical found to reverse symptoms of progeria in human cells Posted: 10 Dec 2015 11:47 AM PST A common, inexpensive and safe chemical called methylene blue could be used to treat progeria -- and possibly the symptoms of normal aging as well. A new study shows for the first time that small doses of methylene blue can almost completely repair defects in cells afflicted with progeria, and can also repair age-related damage to healthy cells.

Computer model could hold key to personalized epilepsy treatment Posted: 10 Dec 2015 11:46 AM PST A computer model that identifies the parts of a person's brain responsible for epileptic seizures could be used to design personalized surgical procedures, researchers say.

Scientists learn how poxviruses defeat the body's host defense Posted: 10 Dec 2015 11:05 AM PST Research shows how smallpox, a feared bioterrorism agent, and other poxviruses overcome the defenses of their hosts. Implications of the findings extend to cancer therapy, researchers say.

Human skin detection technology for improved security, search and rescue Posted: 10 Dec 2015 11:05 AM PST A novel two-dimensional feature space that uses the spectral absorption characteristics of melanin, hemoglobin and water to better characterize human skin has been uncovered by researchers.

Harm reduction services less available in areas plagued by rising IV drug use, HIV infections Posted: 10 Dec 2015 11:05 AM PST Access to harm reduction programs such as syringe exchange is lowest in rural and suburban areas, where rates of addiction to heroin and other opioids are on the rise, according to a study.
