Beer foam secrets tapped in new study

2014-05-14
(Press-News.org) ITHACA, N.Y. – It's an unlikely beer-drinking toast: "Here's to L-T-P-One!" Yet, the secret to optimal foam in the head of a freshly poured brew, according to Cornell food science research, is just the right amount and kind of barley lipid transfer protein No. 1, aka LTP1.

Bitter compounds found in hops, like iso-alpha acids, are important to brewers, says Cornell's Karl J. Siebert, principal investigator and author of "Recent Discoveries in Beer Foam," set for publication in next issue of the Journal of the American Society of Brewing Chemists.

"Dissolved gases in the beer – carbon dioxide and, in some instances, nitrogen – play a role. So do acidity, some ions, ethanol levels, viscosity and numerous other factors that have been tried by brewers and scientifically tested," says Siebert, professor of food science and technology at the New York State Agricultural Experiment Station in Geneva, N.Y. "But LTP1 is the key to perfect beer foam."

Fascinating as foam is to chemists, it's of vital importance for the sensory experience of beer appreciation, insists Siebert, formerly a longtime research chemist in the industry, including at the former Stroh Brewery Co. in Detroit.

"To some beer aficionados, the sign of a good head – the proper consistency, color, height, duration – is to draw a face with your finger in the foam, before taking the first sip," the food scientist notes. "If the face is still there, when the glass is drained and the liquid is gone – that's seriously good foam."

Extended-release medication offers promise for treating alcohol, opioid dependence

2014-05-14
PORTLAND, Ore. – A comparatively new form of a medication for alcohol and opioid dependence that's injected once a month instead of taken orally once a day appears to be significantly more effective than some other medications – because more patients actually continue the prescribed regimen. The findings, published in the Journal of Substance Abuse Treatment by researchers from Oregon State University and other institutions, offer support for a wider use of medications that may help reduce or prevent substance abuse and related hospital admissions. The cost savings ...

Texas A&M-led study shows how 'body clock' dysregulation underlies obesity, more

2014-05-14
COLLEGE STATION – A team of Texas A&M University System scientists have investigated how "body clock dysregulation" might affect obesity-related metabolic disorders. The team was led by Dr. Chaodong Wu, associate professor in the department of nutrition and food sciences of Texas A&M's College of Agriculture and Life Sciences, and Dr. David Earnest, professor in the department of neuroscience and experimental therapeutics, Texas A&M Health Science Center. Study results were published recently on the Journal of Biological Chemistry website at http://www.jbc.org/content/early/2014/04/25/jbc.M113.539601. "Animal ...

A better way to treat ACE inhibitor angioedema in the ED

2014-05-14
CINCINNATI—Investigators at the University of Cincinnati have found a safe and effective treatment for life-threatening angioedema attacks in the emergency department. In angioedema, patients experience a rapid swelling of the skin and subcutaneous tissues—which, in some cases, can lead to airway obstruction and suffocation. Physicians usually treat angioedema like an allergic reaction with corticosteroids and antihistamines. But that therapy doesn't always work for another version of the condition, thought to be caused by taking a class of drugs known as ACE inhibitors. ...

Obesity associated with longer hospital stays, higher costs in total knee replacement patients

2014-05-14
ROSEMENT, Ill.─ Obesity is associated with longer hospital stays and higher costs in total knee replacement (TKR) patients, independent of whether or not the patient has an obesity-related disease or condition (comorbidity), according to a new study published in the Journal of Bone and Joint Surgery (JBJS). More than half of TKR patients have a body mass index (BMI) within the obesity range (greater than 30 kg/m²), which has been linked to a higher risk for related comorbidities such as diabetes, hypertension, osteoarthritis; and in some studies, to higher medical ...

California Central Valley groundwater depletion slowly raises Sierra Nevada mountains

California Central Valley groundwater depletion slowly raises Sierra Nevada mountains
2014-05-14
Winter rains and summer groundwater pumping in California's Central Valley make the Sierra Nevada and Coast Mountain Ranges sink and rise by a few millimeters each year, creating stress on the state's faults that could increase the risk of an earthquake. Gradual depletion of the Central Valley aquifer, because of groundwater pumping, also raises these mountain ranges by a similar amount each year--about the thickness of a dime--with a cumulative rise over the past 150 years of up to 15 centimeters (6 inches), according to calculations by a team of geophysicists. The ...

Societies publish recommendations to guide minimally invasive valve therapy programs for patients

2014-05-14
WASHINGTON, D.C., BEVERLY, MA, and CHICAGO (May 15, 2014) – As minimally invasive therapies are increasingly used to treat diseased heart valves, newly published recommendations provide guidance on best practices for providing optimal care for patients. The document released today offers first-time guidance from four professional medical associations on developing and maintaining a transcatheter mitral valve therapy program, emphasizing collaboration between interventional cardiologists and cardiac surgeons. The document is an important step toward achieving consistent, ...

Inhibiting protein family helps mice survive radiation exposure, Stanford study finds

2014-05-14
STANFORD, Calif. - Tinkering with a molecular pathway that governs how intestinal cells respond to stress can help mice survive a normally fatal dose of abdominal radiation, according to a new study by researchers at the Stanford University School of Medicine. Because the technique is still partially effective up to 24 hours after exposure, the study suggests a possible treatment for people unintentionally exposed to large amounts of radiation, such as first responders at the Chernobyl nuclear disaster in 1986. "We were very surprised by the amount of protection the ...

Antidepressant may slow Alzheimer's disease

Antidepressant may slow Alzheimers disease
2014-05-14
A commonly prescribed antidepressant can reduce production of the main ingredient in Alzheimer's brain plaques, according to new research at Washington University School of Medicine in St. Louis and the University of Pennsylvania. The findings, in mice and people, are published May 14 in Science Translational Medicine. They support preliminary mouse studies that evaluated a variety of antidepressants. Brain plaques are tied closely to memory problems and other cognitive impairments caused by Alzheimer's disease. Stopping plaque buildup may halt the disastrous mental ...

Can anti-depressants help prevent Alzheimers disease?
2014-05-14
PHILADELPHIA – A University of Pennsylvania researcher has discovered that the common selective serotonin reuptake inhibitor (SSRI) citalopram arrested the growth of amyloid beta, a peptide in the brain that clusters in plaques that are thought to trigger the development of Alzheimer's disease (AD). Penn, in collaboration with investigators at Washington University, tested the drug's effects on the brain interstitial fluid (ISF) in plaque-bearing mice and the cerebrospinal fluid (CSF) of healthy human subjects to draw its conclusions, which are detailed in the new issue ...
