New System Teeth
A new braces system utilized by Minneapolis-based dentist Dr. Shamblott straightens adult front teeth with lower cost, less discomfort, and in less time than traditional orthodontics. The new system called Six Month Smiles® utilizes clear brackets and tooth-colored wires so they are far less obvious than typical metal braces. Traditional braces take anywhere from two to four years to straighten teeth because they are correcting both the appearance and the bite of all the teeth in a patient’s mouth. This new system is much faster because it only straightens the front teeth visible in a person’s smile. This also allows for less time and lower force required to make the cosmetic corrections.

People Sensitivity People
Researchers showed video clips that portrayed intentional and accidental harm, and found that all participants, irrespective of their age, paid more attention to people being harmed and to objects being damaged than they did to the perpetrators. Courtesy of Jean Decety

Donor Media Campaign Social Media Social Media Campaign
Cyrus McEachern and his friend Eva Markvoort, a double lung transplant recipient, transformed a single photo into a social media campaign that more than doubled online donor registration rates at B.C. Transplant.
Markvoort died in March of last year, at the age of 25, while waiting for a second lung transplant. She didn’t live to see the success of her work.
“She said she wasn’t ready to go because she hadn’t made enough of an impact,” said McEachern, who spent a lot of time with Markvoort during her final few months.
“But the results of the campaign are an example of how her message and her inspiration continues to benefit the transplant community,”
In 2010, about 173 donors registered online each week. But th

Novel Vaccine Protect
A novel vaccine using the common virus cytomegalovirus (CMV) as the vector or container of proteins from the simian immunodeficiency virus (SIV) protected none of a group of 24 rhesus macaques from infection. But in 13 of the monkeys vaccinated, it did produce infections characterised by an undetectable viral load.
This profound viral suppression led to an apparent decline in the number of SIV-infected cells over a period of two years after infection to the point that SIV-infected cells were undetectable in 72% of monkeys with controlled viremia. Despite this, there was no apparent waning of immune responses to SIV in the all-important effector-memory CD8 and CD4 lymphocytes over this time in twelve of the 13 monkeys.

(Medical Xpress) — In a recent study published in the journal , scientists say that individuals who develop early-onset Alzheimer’s in middle age are at a high risk of being misdiagnosed because many of their initial symptoms are not memory related.
Scientists, led by Dr. Albert Llado from the Hospital Clinic of Barcelona, examined the brain tissue from 40 patients who had suffered from early-onset Alzheimers disease. Of these 40 patients, 15 had not shown any of the typical signs of memory loss. The patients had displayed language disturbances, vision problems and behavioral changes.
