Novel ultrasound technology to screen for heart conditions developed by engineers

Novel ultrasound technology to screen for heart conditions developed by engineers

Engineers at the University of California, San Diego have determined for the first time the impact of a ring-shaped vortex on transporting blood flow in normal and abnormal ventricles within the human heart. They worked with cardiologists at the Non-Invasive Cardiology Laboratory at Gregorio Marañon Hospital, in Madrid, Spain. In order to make the study possible, researchers have developed a novel ultrasound technology that makes screening cheaper and much easier, making it possible to reach a large number of people and even infants.

Tiny carbon nanotube pores make big impact

Tiny carbon nanotube pores make big impact

A team led by the Lawrence Livermore scientists has created a new kind of ion channel consisting of short carbon nanotubes, which can be inserted into synthetic bilayers and live cell membranes to form tiny pores that transport water, protons, small ions and DNA. These carbon nanotube “porins” have significant implications for future health care and bioengineering applications. Continue reading

Traumatic brain injury associated with increased dementia risk in older adults

Traumatic brain injury associated with increased dementia risk in older adults

Traumatic brain injury (TBI) appears to be associated with an increased risk of dementia in adults 55 years and older, according to a study published online by JAMA Neurology . Controversy exists about whether there is a link between a single TBI and the risk of developing dementia because of conflicting study results Continue reading

Significant increase in type 1 diabetes rates among non-Hispanic white youth

Significant increase in type 1 diabetes rates among non-Hispanic white youth

The rate of non-Hispanic white youth diagnosed with type 1 diabetes increased significantly from 2002 to 2009 in all but the youngest age group of children, according to a new study published today in the journal Diabetes . The study included data from more than 2 million children and adolescents living in diverse geographic regions of the United States. Continue reading

Hospital logs staggering 2.5 million alarms in just a month

Hospital logs staggering 2.5 million alarms in just a month

Following the study of a hospital that logged more than 2.5 million patient monitoring alarms in just one month, researchers at UC San Francisco have, for the first time, comprehensively defined the detailed causes as well as potential solutions for the widespread issue of alarm fatigue in hospitals. Their study is in the Oct. 22 issue of PLOS ONE and available online Continue reading

Smoking interferes with neurocognitive recovery during abstinence from alcohol

Smoking interferes with neurocognitive recovery during abstinence from alcohol

Numerous studies have shown that individuals with an alcohol use disorder perform worse than those without one on multiple neurocognitive domains of function following detoxification from alcohol, although the level of impairment can vary widely among individuals. A new study of the degree of neurocognitive recovery in treatment-seeking alcohol dependent individuals (ALC) — with varied degrees of smoking status — during the first eight months of sustained abstinence from alcohol has found that smoking status influenced the rate and level of recovery Continue reading

Understanding drinking behaviors among women with unwanted pregnancies

Understanding drinking behaviors among women with unwanted pregnancies

Most women reduce or stop drinking alcohol upon discovery of pregnancy. However, little information exists about changes in alcohol use, and factors contributing to these changes, among women with unwanted pregnancies Continue reading

Genome editing technique advanced by researchers

Genome editing technique advanced by researchers

Customized genome editing — the ability to edit desired DNA sequences to add, delete, activate or suppress specific genes — has major potential for application in medicine, biotechnology, food and agriculture. Now, in a paper published in Molecular Cell , North Carolina State University researchers and colleagues examine six key molecular elements that help drive this genome editing system, which is known as CRISPR-Cas. NC State’s Dr. Continue reading
