Variation in single amino acid impacts incidence of gastric cancer among Japanese

Researchers at the University of Tokyo uncovered the molecular mechanism driving the activation of a human cancer-causing protein by the CagA pathogenic effector in Helicobacter pylori bacterial strains prevalent in Japan and other East Asian countries, which underlie the higher rate of gastric cancer onset in these regions compared to other parts […]

Biologists discover function of gene linked to familial ALS

MIT biologists have discovered a function of a gene that is believed to account for up to 40 percent of all familial cases of amyotrophic lateral sclerosis (ALS). Studies of ALS patients have shown that an abnormally expanded region of DNA in a specific region of this gene can cause […]

Computers Equal Radiologists in Assessing Breast Density and Associated Breast Cancer Risk

Automated breast-density evaluation was just as accurate in predicting women’s risk of breast cancer, found and not found by mammography, as subjective evaluation done by radiologists, in a study led by researchers at UC San Francisco and Mayo Clinic. Both assessment methods were equally accurate in predicting both the risk […]

Nurses’ care of young mothers leaves traces in babies’ DNA

Researchers have known for a couple of decades that early life adversity can affect the way that particular genes function through a process called epigenetics – a bit like a dimmer switch on a light, pushing gene activity up or down. What they haven’t been able to show until now […]

Decisions, Decisions

Physicians and patients need more guidance to help them navigate the complex array of clinical factors and personal preferences that must be considered when deciding how best to individualize their approach to breast cancer mammography screening. What makes the choice even more complicated is that the benefits of the screening […]

Tracing cerebral cortex evolution

Our cerebral cortex, a sheet of neurons, connections and circuits, comprises “ancient” regions such as the hippocampus and “new” areas such as the six-layered “neocortex”, found only in mammals and most prominently in humans. But when in evolution did the components of cerebral cortex arise and how did they evolve? […]

Fasting boosts stem cells’ regenerative capacity

As people age, their intestinal stem cells begin to lose their ability to regenerate. These stem cells are the source for all new intestinal cells, so this decline can make it more difficult to recover from gastrointestinal infections or other conditions that affect the intestine. This age-related loss of stem […]

Most cardiac patients forgo highly beneficial exercise therapy

Among more than 230,000 cardiac patients who had sustained a heart attack or undergone one of two common heart procedures, only 16 percent participated in a formal exercise program after their hospitalization – despite the program’s demonstrated benefits to health. The finding is published in the print journal Circulation. Lead investigator Alexis Beatty, a […]

UI biomedical engineering students tackle lymphedema in breast cancer patients

When biomedical engineering students Genevieve Goelz, Maria Fernanda Larraga Martinez, Anna Rodriguez, and Ashten Sherman teamed up for their senior design course in September 2017 to find a solution to lymphedema in breast cancer patients, they didn’t know a lot about each other or the medical condition they were tapped […]

Exercising will reduce your risk to develop depression, not matter how old you are or where you are from

Depression is a debilitating condition, significantly reducing the quality of life and oftentimes ending with death. Scientists have been trying to improve depression therapy, but so far results have been limited. But now researchers from The Black Dog Institute, UNSW Sydney and Western Sydney University conducted an international study, which […]

Man vs. Machine?

The ‘deep learning’ computers in Anant Madabhushi’s diagnostic imaging lab at Case Western Reserve University routinely defeat their human counterparts in diagnosing heart failure, detecting various cancers and predicting their strength. But Madabhushi—even as he gladly touts three recent examples of apparent cyber superiority played out in his lab—also dismisses […]

Rabies trick could help treat Parkinsons Disease

The rabies virus wreaks havoc on the brain, triggering psychosis and death. To get where it needs to go, the virus must first trick the nervous system and cross the blood brain barrier — a process that makes it of interest in drug design. Now, scientists report in ACS Nano a way […]

Blueprint for the Skull

Once upon a time in Europe, pregnant women avoided rabbits to prevent their babies from being born with a “harelip.” But, that apparently isn’t the only misconception about the condition now known as cleft lip. In the journal Cell Reports, UConn Health researchers report the popular modern belief that the condition […]

Research Brief: Triple gene combinations study could help predict risk of disease

We inherit many traits from our parents including the color of our eyes and hair. Unfortunately, we also inherit risk factors for certain diseases such as cancer, heart disease, and diabetes. Understanding those genetic connections can help prevention efforts and develop new life-saving treatments to combat these diseases. In the […]

Research Brief: Genes might play unrecognized role in aging, intervention

While aging is familiar to all of us, exactly how it occurs on a molecular basis has been an area of intense study and interest. We take it for granted that different species age at different rates, yet we do not have a good understanding of why and how. Most […]

Long-sought structure of telomerase paves way for drugs for aging, cancer

More than 30 years ago, when UC Berkeley researchers discovered telomerase — an enzyme that lengthens chromosome ends and prevents them from fraying enough to kill a cell — speculation ran wild about its role in aging and cancer, setting off a full-court press to produce drugs to activate or […]

Exercise to change the brain

For someone with Parkinson’s disease (PD), the simple desire to grasp a glass of water can become an insurmountable task, made impossible by the tremors in their hand or arm. Finding strategies to improve these movement impairments is one of the major goals of rehabilitating people with Parkinson’s disease. At […]
