Detecting Dementia's Damaging Effects Before It is Too Late

By studying a rare form of dementia, researchers might have found a way to detect neurodegeneration before brain cells are lost for good. Earlier detection could provide therapeutic drug treatments a chance to work. Scientists might have found an early detection method for some forms of dementia, according to new […]

Injections, exercise promote muscle regrowth after atrophy in mice, study finds

By injecting cells that support blood vessel growth into muscles depleted by inactivity, researchers say they are able to help restore muscle mass lost as a result of immobility. The research, conducted in adult mice, involved injections of cells called pericytes (PERRY-sites), which are known to promote blood vessel growth […]

Opioid-exposed newborns may react to pain differently after birth

Babies exposed to opioids while their mothers were pregnant with them may need special care even before they start to experience withdrawal symptoms, according to Penn State research. Researchers from Penn State College of Medicine found that as soon as 24 and 48 hours after birth, babies who were exposed […]

Transplanted cells reveal early signs of type 1 diabetes

By the time type 1 diabetes is diagnosed, most of the insulin-producing beta cells have already been destroyed. Now, using an innovative transplantation technique, researchers at Karolinska Institutet and University of Miami Miller School of Medicine have been able to intervene to save the beta cells in mice by discovering […]

Direct Oxidative Stress Damage Shortens Telomeres

The same sources thought to inflict oxidative stress on cells—pollution, diesel exhaust, smoking and obesity—also are associated with shorter telomeres, the protective tips on the ends of the chromosomal shoelace. A new study from the University of Pittsburgh, published in Molecular Cell, provides the first smoking gun evidence that oxidative […]

Researchers sequence the genome’s elusive centromere

Though much of the human genome has been sequenced and assembled, scientists have hit road blocks trying to map unassembled regions of DNA that consist mostly of repetitive sequences. One of these regions, found in every cell, is the centromere. Researchers from the University of Rochester, along with their colleagues […]

A new way to wind the development clock of cardiac muscle cells

These days, scientists can collect a few skin or blood cells, wipe out their identities, and reprogram them to become virtually any other kind of cell in the human body, from neurons to heart cells.   The journey from skin cell to another type of functional cell involves converting them into induced pluripotent […]

Mothers with higher quality diets have slimmer, leaner babies

Obesity is a growing problem among toddlers, children and adolescents in the United States. Gaining weight and fat mass rapidly during the first six months of life is one risk factor that can lead to obesity in children. A University of Minnesota School of Public Health study, recently published in the journal Nutrients, […]

IL-1 inhibitors may reduce radiation-induced vascular damage

Radiation therapy against cancer can increase the risk of cardiovascular disease much later in life, as the radiation causes chronic inflammation of the exposed blood vessels. In a new study published in the European Heart Journal, researchers from Karolinska Institutet in Sweden have shown that these inflammations can be treated with […]

New Doctors’ DNA Ages 6 Times Faster Than Normal in First Year

In just a few short weeks, tens of thousands of newly minted doctors will start the most intense year of their training: the first year of residency, also called the intern year. A new study suggests that between now and next summer, that experience will make their DNA age six […]

Researchers find thirty genes for bipolar disorder

An International study which the Danish iPSYCH project has contributed to has now brought us one step closer to understanding why some people suffer from bipolar disorder. After six years of work, researchers from Denmark and abroad have succeeded in uncovering genes which play an important role in the development […]

Missing Molecule Hobbles Cell Movement

Cells missing a certain protein on their surface can’t move normally, UConn researchers reported in Science Signaling. The research could give insight into how cells move and repair wounds in normal tissue, as well as how cancer spreads through the body. Cells are the body’s workers, and they often need to […]

A New Culprit for Multiple Sclerosis Relapses

A molecule that helps blood clot may also play a role in multiple sclerosis relapses, researchers reported in the journal PNAS. The new research may help answer the mystery of why remissions happen, as well as find early markers of the disease. The research also shows a new way to […]

Messenger cells bring good news for bone healing

How do bones heal, and how could they heal better? The answer to these questions may lie in a newly discovered population of “messenger” cells, according to an USC Stem Cell study published in the journal eLife. “With nearly half a million patients in the U.S experiencing failed bone repair every […]

Study Unlocks Secrets of an Elusive Genome Compartment

Although much of the human genome has been sequenced and assembled, scientists have hit roadblocks trying to map unassembled regions of DNA that consist mostly of repetitive sequences, including the centromere. Now, for the first time, researchers from the University of Connecticut and University of Rochester have sequenced all the […]

Scientists pinpoint potential new target for regulating inflammation

Scientists from Trinity have discovered a potential new target for regulating inflammation, which drives a range of diseases including diabetes, cancer and Alzheimer’s.  The potential target is an ancient immune protein – SARM – that has been conserved throughout evolution and thus is very similar in humans, other mammals, flies and worms.

Measuring chromosome imbalance could clarify cancer prognosis

Most human cells have 23 pairs of chromosomes. Any deviation from this number can be fatal for cells, and several genetic disorders, such as Down syndrome, are caused by abnormal numbers of chromosomes. For decades, biologists have also known that cancer cells often have too few or too many copies […]
