New salmonella serotype discovered

Posted: 16 Jan 2015 11:38 AM PST

A new serotype of the salmonella bacteria has been discovered by Texan researchers. Because convention calls for a new serotype to be named after the city in which it is discovered, this one will be called Salmonella Lubbock. And while Lubbock is known for many things, like being the home of Buddy Holly, this new honor will provide new avenues for research into the bacteria's prevention, researchers suggest.

New genetic clues found in fragile X syndrome

Posted: 16 Jan 2015 10:47 AM PST

New insight into fragile X syndrome -- the most common cause of inherited intellectual disability -- has been gained by researchers studying the case of a person without the disorder, but with two of its classic symptoms.

Michigan autoworkers fare worse when it comes to the heart

Posted: 16 Jan 2015 10:47 AM PST

Michigan's autoworkers are at a higher risk of heart disease compared to the US population overall, a study has found for the first time. The research also showed that the prevalence of diabetes among this group was 15.3 percent; double the national average of 7.5 percent at the time of the study.

BPA exposure affects heart health of males, females differently in mouse models

Posted: 16 Jan 2015 10:47 AM PST

Heart function and blood pressure in mice exposed to bisphenol A, BPA, from birth though young adulthood are affected differently in males and females, with females at greater risk of damage from stress, a study has found.

First pharmacological guideline for obesity treatment provides clinical roadmap for anti-obesity drug treatment

Posted: 16 Jan 2015 10:45 AM PST

The first-ever clinical practice guideline for the drug treatment of obesity offers a new tool for health practitioners looking to the latest pharmacotherapy strategies as a means of treating patients with obesity. The Obesity Society says the guideline supplements the TOS/AHA/ACC Obesity Treatment Guidelines to fill a gap in treatment.

Is it possible to reset our biological clocks?

Posted: 16 Jan 2015 06:30 AM PST

Imagine being able to easily get over all of the discomfort and problems of jet lag or night-shift work. Science is not quite there, but recent has opened new therapeutic avenues for improving the synchronization of the body's different biological clocks.

2,500-year-old Pythagoras theorem helps to show when a patient has turned a corner

Posted: 16 Jan 2015 06:24 AM PST

A medical researcher has found the 2,500 year-old Pythagoras theorem could be the most effective way to identify the point at which a patient's health begins to improve.

Bicyclists willing to ride up to 3 miles to catch bus, train

Posted: 16 Jan 2015 06:23 AM PST

Only about 2 percent of commuters in three metro areas - Atlanta, the Twin Cities and Los Angeles - reported pedaling their bicycles to the transit station, suggesting the need for better infrastructure, a researcher reports.

Bone stem cells shown to regenerate bones, cartilage in adult mice

Posted: 16 Jan 2015 06:00 AM PST

A stem cell capable of regenerating both bone and cartilage has been identified in bone marrow of mice. The cells, called osteochondroreticular (OCR) stem cells, were discovered by tracking a protein expressed by the cells. Using this marker, the researchers found that OCR cells self-renew and generate key bone and cartilage cells, including osteoblasts and chondrocytes. The discovery has implications for bone repair, the scientists say.

Tool helps measure patients' readiness to make decisions about starting dialysis

Posted: 16 Jan 2015 05:56 AM PST

A new algorithm is a useful tool for measuring chronic kidney disease patients' readiness for making decisions about initiating dialysis. Patients who have knowledge about their options and have fewer lifestyle barriers to home dialysis are more likely to be ready to make decisions. Doctors who explain all of the treatment options that are available can increase patients' readiness for decision-making, say authors of a new study.

New trick found for how cells stay organized

Posted: 16 Jan 2015 05:56 AM PST

Organization is key to an efficient workplace, and cells are no exception to this rule. New evidence suggests that, in addition to membranes, cells have another way to keep their contents and activities separate: with ribbons of spinning proteins.

Rare mutations do not explain 'missing heritability' in asthma

Posted: 16 Jan 2015 05:55 AM PST

Rare genetic mutations have been thought to explain missing heritability, but it appears they are unlikely to play a major role. Analyzing the coding regions of genomes of more than 11,000 individuals, scientists identified mutations in just three genes that were associated with asthma risk. Each was associated with risk in specific ethnicities, suggesting gaps in the current understanding of asthma genetics.

Investigations and complaints procedures have a serious impact on doctors' health, risk harming patients, study suggests

Posted: 16 Jan 2015 05:53 AM PST

Doctors who are the subject of complaints procedures or investigation by the General Medical Council experience high rates of serious depression and anxiety as well as suicidal thoughts, according to a new study based in England.

New 'triggered-release' mechanism could improve drug delivery

Posted: 16 Jan 2015 05:49 AM PST

More efficient medical treatments could be developed thanks to a new method for triggering the rearrangement of chemical particles, scientists say. The new method uses two 'parent' nanoparticles that are designed to interact only when in proximity to each other and trigger the release of drug molecules contained within both The release of the drug molecules from the 'parent' nanoparticles could subsequently form a third 'daughter' particle, which comprises molecules from both 'parent' nanoparticles, researchers explain.

Could our brain instruct our bodies to burn more fat?

Posted: 15 Jan 2015 10:48 AM PST

By uncovering the action of two naturally occurring hormones, scientists may have discovered a way to assist in the shedding of excess fat. Fat in adult humans is typically stored in adipocytes, specialized cells that comprise white fat. But around the neck and shoulders, there is a second form of fat made of brown adipocytes. Rather than storing fat, these cells can be induced to burn it off, experts say.
