Human-gut-on-a-chip model offers hope for patients suffering from IBD

It's estimated that as many as 1,000,000 Americans suffer from inflammatory bowel diseases (IBD), such as ulcerative colitis and Crohn's disease, which cause mild to severe symptoms that at best can be managed and at worst can lead to life-threatening complications.

CTE can be diagnosed by neuropathological examination of brain tissue

For the first time, CTE has been confirmed as a unique disease that can be definitively diagnosed by neuropathological examination of brain tissue. A consensus panel of expert neuropathologists concluded that CTE has a pathognomonic signature in the brain, an advance that represents a milestone for CTE research and lays the foundation for future studies defining the clinical symptoms, genetic risk factors and therapeutic strategies for CTE.

Bile acid may help treat fatty liver disease and obesity

A bile acid that can turn off a receptor in the gut has prevented and reversed fatty liver disease in mice, according to an international team of researchers. The compound may help treat certain metabolic disorders, such as Type 2 diabetes and obesity, as well.

Simple diagnostic test can help fight deadly sleeping sickness

Scientists have developed a quick and simple diagnosis method, similar to a dipstick pregnancy test, to fight a deadly sleeping sickness.

Researchers identify dazzling new method for visualizing neurons

Researchers have discovered a dazzling new method of visualizing neurons that promises to benefit neuroscientists and cell biologists alike: by using spectral confocal microscopy to image tissues impregnated with silver or gold.

IIASA researchers provide new measures to replace old-age dependency ratio

Conventional measures of age usually define people as 'old' at one chronological age, often 65. In many countries around the world, age 65 is used as a cutoff for everything from pension age to health care systems, as the basis of a demographic measure known as the 'old-age dependency ratio,' which defines everyone over 65 as depending on the population between ages 20 and 65.

TSRI scientists track how HIV-fighting antibodies develop over time

In a new study, a team led by scientists at The Scripps Research Institute tracked how a family of these HIV-fighting antibodies develops over time. The research shows how a future vaccine might trigger the immune system to produce these antibodies more effectively.

Older adults experience problems in processing multisensory information

Much like trying to watch a video with the audio out of synch, older adults may have difficulty combining the stimuli they see and hear, and it could have implications for rapid decision-making tasks such as driving, according to new research.

Patients can be trained to safely self-administer long-term IV antibiotics, say UT Southwestern physicians

Uninsured patients can be trained to safely and efficiently self-administer long-term intravenous antibiotics, UT Southwestern Medical Center physicians have found, a result that may have profound implications for patient treatment at public hospitals across the country.

Prophylaxis treatment can protect children who receive liver transplants from HBV-infected donors

Researchers have found that a prophylaxis treatment can prevent new-onset hepatitis B in children who receive liver transplants from donors who were previously infected with hepatitis B virus (HBV) but had successfully cleared the virus.

Study: Preoperative use of blood-thinning drugs associated with decreased risk of blood clots

Among patients undergoing major cancer operations, the preoperative use of blood-thinning drugs such as heparin does not increase rates of major bleeding or transfusions, and is associated with a decreased risk of blood clots, according to new study results published online in the Journal of the American College of Surgeons ahead of print publication early next year.

New study may help understand how estrogens affect cognition and memory in women

A new study by University of Guelph researchers that narrows down where and how estrogens affect the brain may help in understanding how the hormones affect cognition and memory in women, says psychology professor Elena Choleris.

BUSM researchers explore how do not resuscitate orders affect hospital rankings for pneumonia

Researchers from Boston University School of Medicine examined how hospital differences in patient preferences for life-sustaining treatments (do not resuscitate, or DNR, orders) affected hospital rankings for pneumonia.

Molecular signatures can predict flu vaccine responses in young and old

What factors inhibit strong responses to seasonal flu vaccines in the elderly? Why do anti-flu antibodies last longer after vaccination in some people? Answers are emerging from an Emory University-based systems biology analysis of blood samples from more than 400 volunteers who received seasonal flu vaccines. Bali Pulendran, PhD, led a team of researchers who tracked patterns of gene expression, known as molecular signatures, of strong immune responses in volunteers' blood across five consecutive seasons from 2007 to 2011.

Cancer drug may protect kidneys from damage caused by chemotherapy agent cisplatin

A class of drugs used increasingly to help fight cancer may have the additional benefit of protecting the kidneys when packaged with the powerful chemotherapy agent cisplatin.

U of T researchers find another clue in understanding the cause of MS

Researchers at the University of Toronto have found another clue in understanding the cause of what drives Multiple Sclerosis (MS) disease. Their findings were published today in Immunity.

Innovative brain imaging study reveals why ToM deficiencies present in children with ASD

The holidays can be difficult for children with autism spectrum disorder (ASD), particularly because of new or different social situations. One reason scientists believe ASD causes impairment in social interactions is due to an inability to effectively infer other's thoughts and feelings through "theory of mind," or ToM -- the ability to understand the mental states of others and oneself.

Shingles vaccine can help protect elderly patients with end-stage renal disease

Elderly patients with end-stage renal disease (ESRD) who received the shingles vaccine were half as likely to develop shingles compared to those who were not vaccinated. The new study from Kaiser Permanente, published in Clinical Infectious Diseases, also found the best protection against shingles was achieved when patients received the vaccination shortly after beginning dialysis.

UW-Madison scientist creates serotonin neurons from stem cells

Su-Chun Zhang, a pioneer in developing neurons from stem cells at the University of Wisconsin-Madison, has created a specialized nerve cell that makes serotonin, a signaling chemical with a broad role in the brain.

Columbia Engineering professor wins grant to study tendon-to-bone integration for rotator cuff repair

Helen H. Lu, professor of biomedical engineering at Columbia Engineering, has won a three-year $1.125 million Translational Research Award grant from the Department of Defense's Congressionally Directed Medical Research Programs for her research on tendon-to-bone integration for rotator cuff repair.
