Preserving Fertility in Pediatric Cancer Survivors

One in three childhood cancer survivors is at risk of becoming infertile due to chemotherapy or radiation, and since their sperm or eggs have not matured, assisted reproduction using those sperm or eggs is not an option when they become adults. Now in a major first, researchers at the University of […]

Antibodies stabilise plaque in arteries

Researchers at Karolinska Institutet have found that type IgG antibodies play an unexpected role in atherosclerosis. A study on mice shows that the antibodies stabilise the plaque that accumulates on the artery walls, which reduces the risk of it rupturing and causing a blood clot. It is hoped that the results, […]

Perivascular spaces linked to worse cognition

Enlarged perivascular spaces, which are commonly seen on brain MRIs in older adults, have important associations with worse cognitive performance, particularly information processing speed and executive function, according to a new study that challenges historical consideration that perivascular spaces are a harmless imaging marker. Enlarged perivascular spaces are fluid-filled spaces […]

Prenatal allergies prompt sexual changes in offspring

A single allergic reaction during pregnancy prompts sexual-development changes in the brains of offspring that last a lifetime, new research suggests. Female rats born to mothers exposed to an allergen during pregnancy acted more characteristically “male” – mounting other female rodents, for instance – and had brains and nervous systems […]

Neutrons paint atomic portrait of prototypical cell signaling enzyme

Direct observations of the structure and catalytic mechanism of a prototypical kinase enzyme—protein kinase A or PKA—will provide researchers and drug developers with significantly enhanced abilities to understand and treat fatal diseases and neurological disorders such as cancer, diabetes, and cystic fibrosis. Kinases are a large group of hundreds of […]

Eisai's Initiation of Phase III Clinical Trial of BAN2401 in Early Alzheimer's Disease

Eisai Co., Ltd. announced that a global Phase III clinical study (Clarity AD/Study 301) of BAN2401, an anti-amyloid beta protofibril antibody, in patients with early Alzheimer's disease has been initiated. BAN2401 is being jointly developed by Eisai and Biogen Inc. Clarity AD is a global placebo-controlled, double-blind, parallel-group, randomized study […]

'Tremendous Contributions' for Developmental Biology

Professor Otger Campàs receives 2019 Elizabeth D. Hay New Investigator Award from the Society for Developmental Biology. How do we develop from a mass of undifferentiated cells into organisms of tissues and organs with specific three-dimensional morphologies and architectures? That question has been one of the perennial mysteries at the […]

Gene Therapy Shows Initial Promise for Parkinson’s Disease

A delicate operation that involved placing a gene into the brain was found to reduce the severity of motor symptoms in patients with moderately advanced Parkinson’s disease, whose symptoms were no longer controlled by their medications. In a phase I gene therapy trial led by UC San Francisco, 15 patients […]

Research paves way for new source for leukemia drug

Chemistry researchers at Oregon State University have developed a method for making anti-leukemia compounds that until now have only been available via an Asian tree that produces them. The synthesis of cephalotaxine and homoharringtonine (HHT) paves the way toward less-expensive, more readily available leukemia drugs whose production is not subject […]

Scientists narrow in on cells that drive immune response to cancer

Immunotherapy, using the body’s own immune system to target and destroy cancer cells, is one of the most promising frontiers in cancer research, but many patients do not respond to the therapies for reasons not fully understood. Scientists at the Yale Systems Biology Institute have taken a step closer to understanding how […]

Restoring hearing loss

A team of worldwide researchers including engineers from the University of Utah have received a $9.7-million grant to design and develop a new implantable device and surgical procedure for the deaf that hopefully will cut through the noise and produce much more detailed sound than traditional hearing-loss treatments. This new […]

Engineering Researcher Explains why Time Seems to Fly as we get Older

“Why does it feel that the time passes faster as we get older? What is the physical basis for the impression that some days are slower than others? Why do we tend to focus on the unusual (the surprise), not on the ever present?,” asks Adrian Bejan, the J.A. Jones […]

‘Selfish’ genetics amplify inflammation, age-related diseases

Aging affects every living organism, but the molecular processes that contribute to aging remain a subject of debate. While many things contribute to the aging process, one common theme in animal aging is inflammation—and this may be amplified by a class of selfish genetic elements. The human genome is littered […]

Protective antibodies also found in premature babies

Even premature babies carry anti-viral antibodies transferred from the mother, researchers at Karolinska Institutet in Sweden report in a paper on maternal antibodies in newborns, published in the journal Nature Medicine. The results should change our approach to infection sensitivity in newborns, they say. Antibodies are transferred from the mother’s blood […]

Experimental blood test accurately spots fibromyalgia

For the first time, researchers have evidence that fibromyalgia can be reliably detected in blood samples – work they hope will pave the way for a simple, fast diagnosis. In a study that appears in the Journal of Biological Chemistry, researchers from The Ohio State University report success in identifying biomarkers of […]

Green tea cuts obesity, health risks in mice

Green tea cut obesity and a number of inflammatory biomarkers linked with poor health in a new study. Mice fed a diet of 2 percent green tea extract fared far better than those that ate a diet without it, a finding that has prompted an upcoming study of green tea’s […]

Narcolepsy may be caused by the body attacking itself

Researchers from DTU and the University of Copenhagen are now pointing out that narcolepsy is an autoimmune disease. This may be important to future treatment of this chronic disorder. Between 2,500 and 3,000 Danes suffer from the sleep disorder narcolepsy—which is characterized by a sudden and overwhelming urge to sleep. […]

Speed limit on DNA-making sets pace for life’s first steps

Scientists puzzled for two decades over this seemingly unnecessary withholding. Now researchers at Princeton University have shown that the inhibiting mechanism, controlled by an enzyme known as RNR, is key to the embryo’s survival. Too much material early on leads to disaster for the fledgling lifeform. “This study shows us […]

Grow a better jawbone in your ribs

The jawbone is not typically connected to the rib bone, but it might be in an emergency. Rice University bioengineers and their colleagues have developed a technique to grow live bone to repair craniofacial injuries by attaching a 3D-printed bioreactor — basically, a mold — to a rib. Stem cells and blood vessels from […]

With single gene insertion, blind mice regain sight

It was surprisingly simple. University of California, Berkeley, scientists inserted a gene for a green-light receptor into the eyes of blind mice and, a month later, they were navigating around obstacles as easily as mice with no vision problems. They were able to see motion, brightness changes over a thousandfold […]

Light physical activity linked to lower risk of heart disease in older women

Light physical activity such as gardening, strolling through a park, and folding clothes might be enough to significantly lower the risk of cardiovascular disease among women 63 and older, a new study has found. This kind of activity, researchers said, appears to reduce the risk of cardiovascular disease events such […]

Surgery no better than medication at preventing serious complications of atrial fibrillation

Catheter ablation, a common cardiovascular procedure, appears no more effective than drug therapies in preventing strokes, deaths, and other complications in patients with atrial fibrillation. However, patients who get the procedure experience much greater symptom relief and long-term improvements in the quality of life, including  fewer recurrences of the condition […]

Colorectal Cancer Screening Might Need to Start Sooner Than You Thought

Thinking you could wait till your 50th birthday to worry about colorectal cancer? Maybe not. New guidelines from the American Cancer Society recognize recent studies that have found increasing rates of colorectal cancer among younger people. In response, they lowered the recommended age to begin screening from 50 to 45. “Research […]
