Feeling Full During Weight Loss May Depend On Flavor And Texture

Date: Nov-01-2012
Low calorie foods may help people lose weight but there is often a problem that people using them do not feel full. New research published in BioMed Central's open access journal Flavour shows that subtle manipulations of texture and creamy flavour can increase the expectation that a fruit yoghurt drink will be filling and suppress hunger regardless of actual calorific content...

"Maintenance-First" Program Before Weight Loss Helps Women Avoid Yo-Yo Dieting

Date: Nov-01-2012
Would you take part in a weight-loss program in which you were explicitly asked not to lose any weight for the first eight weeks? Although the approach sounds counterintuitive, a study from researchers at the Stanford University School of Medicine found that women who spent eight weeks mastering weight-maintenance skills before embarking on a weight-loss program shed the same number of pounds as women who started a weight-loss program immediately...

Import Of Proteins Into Chloroplasts Is Differentially Regulated By Age

Date: Nov-01-2012
New research has found that the transport of proteins into chloroplasts in plants is differentially regulated by the age of the chloroplast; upturning the previously accepted notion that this process is age-independent or only globally up- or down- regulated for all proteins. The research, led by Dr. Hsou-min Li, a Research Fellow from the Institute of Molecular Biology, Academia Sinica of Taiwan, is published in the open access journal PLOS Biology...

Monkeys Help Researchers Study How The Brain Measures Time

Date: Nov-01-2012
Researchers at the University of Minnesota's Center for Magnetic Resonance Research (CMRR) have found a small population of neurons that is involved in measuring time, which is a process that has traditionally been difficult to study in the lab. In the study, which is published in the open access journal PLOS Biology, the researchers developed a task in which monkeys could only rely on their internal sense of the passage of time. Their task design eliminated all external cues which could have served as "clocks"...

In Uterine Cancer, A Shorter Interval Of Time Between Hysterectomy And Start Of Radiation Treatment Recommended

Date: Nov-01-2012
Waiting too long after a hysterectomy to begin radiation therapy may increase the risk of uterine cancer recurrence, according to a new study from researchers at Henry Ford Hospital in Detroit. The study shows that for patients with uterine cancer not receiving chemotherapy, tumors were more likely to return if radiation therapy was delayed nine weeks or longer following surgery, with only 43 percent having relapse-free survival after five years. By comparison, patients starting radiation treatment soon after surgery had a five-year relapse-free survival of 90 percent...

Lupus Increases Risk For Preeclampsia In Pregnancy

Date: Nov-01-2012
New research reports that women with systemic lupus erythematosus (SLE) have a two-fold increase in risk of preeclampsia - a dangerous condition in which pregnant women develop high blood pressure (hypertension) and protein in their urine (proteinuria) after 20 weeks of gestation...

Association Between Metabolic Syndrome And Heart Disease Risk For Women On Hormone Therapy

Date: Nov-01-2012
A new analysis of the Women's Health Initiative (WHI) trials show that women who had metabolic syndrome before they started hormone therapy had a greatly increased risk of heart attack or dying of heart disease. Women who didn't have metabolic syndrome beforehand showed no increased risk. The study was published online in Menopause, the journal of the North American Menopause Society. "Our findings emphasize the importance of assessing cardiovascular disease risk status when hormone therapy is considered for relief of menopausal symptoms," wrote the WHI investigators who authored the study...

In Children With Autism, Distinct Developmental Patterns Identified During Their First 3 Years

Date: Nov-01-2012
In the largest prospective study to date of children with early and later manifestation of autism spectrum disorders (ASD) compared to children without ASD, researchers found two distinct patterns of language, social and motor development in the children with ASD. Published in the journal Child Development, the study found that early in development, children who display early signs of ASD show greater initial delay across multiple aspects of development compared to children whose ASD symptoms emerge later...

Medical Schools Need To Provide More Education On Obesity

Date: Nov-01-2012
Although there is an increasing number of people struggling with obesity, there are only a few medical schools in the United States providing sufficient, beneficial instructions on how to address weight problems in obese patients. The finding came from a team of experts at Wake Forest Baptist Medical Center and was published in the journal Teaching and Learning in Medicine. Obesity is a serious issue in America, with over one-third of adults and one-sixth of kids who are obese...

Scientists Unlock Chemical Processes Behind Argyria - Silver Turning People Blue

Date: Nov-01-2012
Researchers from Brown University have shown for the first time how ingesting too much silver can cause argyria, a rare condition in which patients' skin turns a striking shade of grayish blue. "It's the first conceptual model giving the whole picture of how one develops this condition," said Robert Hurt, professor of engineering at Brown and part of the research team. "What's interesting here is that the particles someone ingests aren't the particles that ultimately cause the disorder." Scientists have known for years argyria had something to do with silver...
