Study shows light therapy to effectively treat mood disorders, including SAD

...y approach is "dawn simulation," which attempts to simulate an earlier dawn through exposure to artificial light. This follows the theory that SAD is triggered by the reduced period of bright daylight during winter. The method attempts to recreate the increased intensity of sunlight that occurs in nature in ...

US service academies to collaborate with UNC, Andrews Air Force Base, Duke in knee injury study

...is is a standardized jump-landing task designed to simulate the forces on the ACL during vigorous physical activity. The study participant jumps down from the elevated take-off box and lands on a force plate. He or she then immediately jumps vertically as high as possible. The force plate and a transmitter, ...

Liver may be source of 'good' cholesterol

...t on a project that used gene-targeting in mice to simulate a rare disease in people Tangier disease. People with this genetic disease produce virtually no "good" cholesterol. "In studies of mice, we provided the first definitive proof that the liver is the source of about 80 percent of the high-density lip...

Breast tumor's biological traits guide hormone therapy

...atical model using emerging clinical trial data to simulate 10-year disease-free survival in postmenopausal women with hormone-receptor positive breast cancer. "The simulations we ran suggest that the best treatment strategy is determined by the tumor's biology, and that not all patients should necessarily be...

Sildenafil (Viagra) approved for treatment of pulmonary arterial hypertension (PAH) as Revatio

...mans: The changes observed in healthy mountaineers simulate disease processes in patients suffering from chronic lung diseases. This high altitude study clearly documented the selective pulmonary vasodilatory effect of sildenafil. The substance reduces pulmonary hypertension, improves gas exchange and increas...

A vaccine approach to treating Parkinson's disease

... mice that are specially bred by Masliah's team to simulate Parkinson's disease, resulting in reduced build-up of abnormal alpha-synuclein. The accumulation of abnormal alpha-synuclein is associated with degeneration of nerve cells and interference with normal inter-cellular communication, leading to Parkins...

Female volunteers prepare for a second 'bedrest'

...completed 60 days of voluntary bedrest in order to simulate the physiological effects of weightlessness on the human body. The research team in Toulouse, France, is now actively seeking twelve new volunteers to enable them to continue and enhance the research. At the beginning of June, the twelve volunteers f...

Every second counts for shaken babies

... of Civil Engineering to see if it was possible to simulate the mechanics of Shaken Baby Syndrome. He said the model would not only help predict injuries but could help form guidelines for caring for and handling babies. It would also allow more accurate evidence to be given in court and help develop safer ...

Researchers model avian flu outbreak, impact of interventions

...gust 5). The researchers used computer modeling to simulate what might happen if avian flu were to start passing efficiently between people in Southeast Asia. They found that antiviral treatment is a critical component of any multi-pronged approach. The computer simulations are part of the Models of Infectio...

Contaminated water presents bigger crisis in the Gaza strip

... patterns in the area. Second, models were used to simulate the different water flow patterns along the border between Israel and the Gaza Strip. The third level of the project provided management scenarios tested by mathematical models. "At present, the ground water in the Gaza Strip is the only source of...

Artificial cervical disc replacement offered for neck and arm pain problems

...urgery. "The goal is to find an implant that can simulate the natural function of the cervical disc and restore the physiologic motion of the cervical spine," said Phillips. The PCM Artificial Cervical Disc combines the use of metal and plastic, the same materials that have been in use for 30 years in hip ...

Rutgers-Newark psychology researchers reveal link between body and action perception

...of body perception would also affect their ability simulate others' actions while observing them." The tasks involved individuals observing someone lifting a box and attempting to determine and report the object's weight. In some of the instances, the individuals doing the lifting were correctly informed of t...

Satellite survey of Elbe flood helps Swiss Re insure for disaster

...menting the course of the last flood we can better simulate future flood events. We can also match the images to land-use maps, and assess risk down to the scale of individual postcodes, the satellite imagery showing us what percentage of a given postcode has been flooded." Ebel added he saw potential for Ea...

Talk therapy more effective long term treatment for SAD than light therapy, study finds

... the white fluorescent or full-spectrum light will simulate sunlight and make them feel better. The treatment works reasonably well but is hard to stick with, so Kelly Rohan, a SAD expert and assistant professor of psychology at the University of Vermont, views it as more a quick fix than long-term solution....

Cancer prevention news tips

...liver cancer. The researchers used rat models that simulate precancerous liver tumors caused by a carcinogen called aflatoxin. Aflatoxin is produced by microscopic molds found on dietary staples, such as corn and peanuts. It also is known to cause liver cancer in people infected with hepatitis B. "We know t...

Hopkins study proves cochlear implants prevent or reverse damage to brain's auditory nerve system

...e complicated. Composed of two parts, the devices simulate hearing by picking up sound through an external microphone located behind the ear and outside the scalp and then transmitting sound as electrical signals across the skin to an implanted receiver that is directly attached to the brain. In the Science ...

Role of nervous system in fatal heart rhythm under study

Could a simple test save Medicare hundreds of millions?

... used a computer model called a Markov analysis to simulate the costs, benefits, and health outcomes of 65-year-old individuals who meet the MADIT-2 trial criteria for Medicare coverage of an ICD. They looked at three scenarios: all such patients get an ICD, only those with positive or inconclusive MTWA resul...
