Mental rest and reflection boost learning, study suggests

A new study, which may have implications for approaches to education, finds that brain mechanisms engaged when people allow their minds to rest and reflect on things they’ve learned before, may boost later learning. Scientists have already established that resting the mind, as in daydreaming, helps strengthen memories of events and retention of information. In a new twist, researchers at The University of Texas at Austin have shown that the right kind of mental rest, which strengthens and consolidates memories from recent learning tasks, helps boost future learning.

Patients treated with radiation therapy who have tumors in left breast have comparable overall survival to those with tumors in right breast

Patients treated with radiation therapy who have tumors in left breast have comparable overall survival to those with tumors in right breast

Tumor laterality (left-side vs. right-side) does not impact overall survival in breast cancer patients treated with breast-conserving surgery and adjuvant external beam radiation therapy, according to a study published in the October 1, 2014 issue of the International Journal of Radiation Oncology • Biology • Physics (Red Journal), the official scientific journal of the American Society for Radiation Oncology (ASTRO). Studies have shown that breast cancer patients treated with radiation therapy have improved local-regional recurrence, and breast cancer-specific survival after breast-conserving surgery and overall survival (OS) after mastectomy Continue reading

Cystic Fibrosis lung infection: Scientists open black box on bacterial growth

Cystic Fibrosis lung infection: Scientists open black box on bacterial growth

Researchers from the University of Copenhagen have shown for the first time how bacteria can grow directly in the lungs of Cystic fibrosis patients, giving them the opportunity to get tremendous insights into bacteria behavior and growth in chronic infections. The study also discovered the bacterial growth in chronic lung infections among cystic fibrosis (CF) patients was halted or slowed down by the immune cells. The researchers discovered the immune cells consumed all the oxygen and helped “suffocate” the bacteria, forcing the bacteria to switch to a much slower growth. Continue reading

Presence of enzyme may worsen effects of spinal cord injury and impair long-term recovery

Presence of enzyme may worsen effects of spinal cord injury and impair long-term recovery

Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma. Through a series of sophisticated experiments, researchers reporting in The American Journal of Pathology suggest that matrix metalloproteinase-3 (MMP-3) plays a pivotal role in disruption of the brain/spinal cord barrier (BSCB), cell death, and functional deficits after SCI.

Scientists find ‘hidden brain signatures’ of consciousness in vegetative state patients

Scientists find ‘hidden brain signatures’ of consciousness in vegetative state patients

Scientists in Cambridge have found hidden signatures in the brains of people in a vegetative state, which point to networks that could support consciousness even when a patient appears to be unconscious and unresponsive. Continue reading

Dental anxiety can be so extreme for some patients that a simple cotton swab on the gums makes them flinch. Continue reading

New cancer drug to begin trials in multiple myeloma patients

New cancer drug to begin trials in multiple myeloma patients

Scientists at Imperial College London have developed a new cancer drug which they plan to trial in multiple myeloma patients by the end of next year. In a paper published today in the journal Cancer Cell , the researchers report how the drug, known as DTP3, kills myeloma cells in laboratory tests in human cells and mice, without causing any toxic side effects, which is the main problem with most other cancer drugs. The new drug works by stopping a key process that allows cancer cells to multiply Continue reading

Impact of patient-to-physician messaging reviewed in study

Email has become one of the most widespread forms of communication, with its streamlined interactions benefiting both businesses and individuals. With the advent of secure patient web portals and the faith that online access has the potential to improve care, the medical industry is slowly catching up Continue reading

Computerized surveillance system quickly detects disease outbreaks among preschoolers

Computerized surveillance system quickly detects disease outbreaks among preschoolers

A web-based system that allows preschools and child care centers to report illnesses to local public health departments could improve the detection of disease outbreaks and allow resources to be mobilized more quickly, according to University of Michigan research to be presented Saturday, Oct. 11 at the American Academy of Pediatrics (AAP) National Conference & Exhibition in San Diego. Researchers who designed the biosurveillance system will describe how it can be used to track illness trends and improve public health response to outbreaks during a presentation at 2:09 p.m Continue reading
