The latest Special Issue from ecancermedicalscience is dedicated to the memory of our late friend, Dr Mario Sideri. The Special Issue, "Prevention of gynaecological cancers: in memory of Mario Sideri," consists of nine articles centred around Dr Sideri's favoured research topic. Dr Sideri was one of the first doctors in the world to identify the connection between the human papillomavirus (HPV) and cervical cancer. He served as the Director of the Preventive Gynecology Unit at the European Institute of Oncology (IEO) in Milan from 1994 until his tragic death in June ...

When it comes to cracking nuts, wild bearded capuchin monkeys are more skilled than anyone had given them credit for, according to researchers who report new findings in the Cell Press journal Current Biology on April 30. The monkeys are known to use stone "hammers" to crack nuts. The new study shows that the monkeys are quite careful about the amount of force delivered to those nuts. They adjust the force applied with each strike based on the condition of the nutshell, making it less likely that they'll end up smashing the tasty kernel inside. "Wild bearded capuchin ...

Bats are masters of flight in the night sky, capable of steep nosedives and sharp turns that put our best aircraft to shame. Although the role of echolocation in bats' impressive midair maneuvering has been extensively studied, the contribution of touch has been largely overlooked. A study published April 30 in Cell Reports shows, for the first time, that a unique array of sensory receptors in the wing provides feedback to a bat during flight. The findings also suggest that neurons in the bat brain respond to incoming airflow and touch signals, triggering rapid adjustments ...

Neuroscientists have perfected a chemical-genetic remote control for brain circuitry and behavior. This evolving technology can now sequentially switch the same neurons - and the behaviors they mediate - on-and-off in mice, say researchers funded by the National Institutes of Health. Such bidirectional control is pivotal for decoding the brain workings of complex behaviors. The findings are the first to be published from the first wave of NIH grants awarded last fall under the BRAIN Initiative. "With its new push-pull control, this tool sharpens the cutting edge of ...

The feeling of being inside one's own body is not as self-evident as one might think. In a new study from Sweden's Karolinska Institutet, neuroscientists created an out-of-body illusion in participants placed inside a brain scanner. They then used the illusion to perceptually 'teleport' the participants to different locations in a room and show that the perceived location of the bodily self can be decoded from activity patterns in specific brain regions. The sense of owning one's body and being located somewhere in space is so fundamental that we usually take it for granted. ...

First study to show pattern of telomere changes at multiple time points as cancer develops Telomeres can look 15 years older in people developing cancer Pattern suggests when cancer hijacks the cell's aging process CHICAGO -- A distinct pattern in the changing length of blood telomeres, the protective end caps on our DNA strands, can predict cancer many years before actual diagnosis, according to a new study from Northwestern Medicine in collaboration with Harvard University. The pattern -- a rapid shortening followed by a stabilization three or four years before ...

Rochester, Minn. -- Over the last decade, numerous studies have shown that many Americans have low vitamin D levels and as a result, vitamin D supplement use has climbed in recent years. Vitamin D has been shown to boost bone health and it may play a role in preventing diabetes, cancer, cardiovascular disease and other illnesses. In light of the increased use of vitamin D supplements, Mayo Clinic researchers set out to learn more about the health of those with high vitamin D levels. They found that toxic levels are actually rare. Their study appears in the May issue of ...

LA JOLLA--Stem cells, which have the potential to turn into any kind of cell, offer the tantalizing possibility of generating new tissues for organ replacements, stroke victims and patients of many other diseases. Now, scientists at the Salk Institute have uncovered details about stem cell growth that could help improve regenerative therapies. While it was known that two key cellular processes--called Wnt and Activin--were needed for stem cells to grow into specific mature cells, no one knew exactly how these pathways worked together. The details of how Wnt and Activin ...

Many human communities want answers about the current status and future of Arctic marine mammals, including scientists who dedicate their lives to study them and indigenous people whose traditional ways of subsistence are intertwined with the fate of species such as ice seals, narwhals, walruses and polar bears. But there are many unknowns about the current status of 11 species of marine mammals who depend on Arctic sea ice to live, feed and breed, and about how their fragile habitat will evolve in a warming world. A recently published multinational study attempted ...

AUSTIN, Minn. (4/30/15) - Taking aspirin reduces a person's risk of colorectal cancer, but the molecular mechanisms involved have remained unknown until a recent discovery by The Hormel Institute, University of Minnesota. Researchers led by The Hormel Institute's Executive Director Dr. Zigang Dong and Associate Director Dr. Ann M. Bode, who co-lead the Cellular & Molecular Biology section, discovered that aspirin might exert its chemopreventive activity against colorectal cancer, at least partially, by normalizing the expression of epidermal growth factor receptor (EGFR) ...

New York, NY (April 30, 2015) - The use of integrative medicine interventions leads to significant improvements in patient activation and patient-reported outcomes in the treatment of chronic pain, depression, and stress, according to a new report released by The Bravewell Collaborative. The findings are based on data collected by the Patients Receiving Integrative Medicine Interventions Effectiveness Registry (PRIMIER), the first-ever patient registry on integrative medicine. "We are encouraged by these early results, and we see tremendous potential for PRIMIER to provide ...

HOUSTON - (April 30, 2015) - The percentage of Texans without health insurance dropped 31 percent since enrollment began in the Affordable Care Act's (ACA) Health Insurance Marketplace, according to a new report released today by the Episcopal Health Foundation and Rice University's Baker Institute for Public Policy. The report found that from September 2013 to March 2015, the percentage of uninsured adult Texans ages 18-64 dropped from 25 to 17 percent. "This is a dramatic drop that's unprecedented in Texas," said Elena Marks, president and CEO of the Episcopal Health ...

Due to a lack of suitable studies, no conclusions can be drawn on the patient-relevant benefit or harm of screening for asymptomatic bacteriuria (ASB) in pregnant women. The benefit of antibiotic treatment of ASB following screening is also an open issue, as the results of the over 40-year-old studies cannot be applied to the current healthcare situation. This is the result of the final report published by the German Institute for Quality and Efficiency in Health Care (IQWiG) on 23 April 2015, which was commissioned by the Federal Joint Committee (G-BA). Maternity guidelines ...

This news release is available in French. Quebec City, April 30, 2015--Noroviruses, a group of viruses responsible for over 50% of global gastroenteritis cases, can spread by air up to several meters from an infected person according to a new study by Université Laval researchers. The discovery, details of which are presented in the latest issue of Clinical Infectious Diseases, suggests that measures applied in hospitals during gastroenteritis outbreaks may be insufficient to effectively contain this kind of infection. The team led by Caroline Duchaine, professor ...

TAMPA, Fla. - DNA can be damaged by different environmental insults, such as ultraviolet light, ionizing radiation, oxidative stress or certain drugs. If the DNA is not repaired, cells may begin growing uncontrollably, leading to the development of cancer. Therefore, cells must maintain an intricate regulatory network to ensure that their DNA remains intact. Moffitt Cancer Center researchers have discovered a novel mechanism that controls a cell's response to DNA damage. The protein SIRT1 plays an important role in controlling DNA damage. It can sense the presence of ...

Few doctors are prescribing a low-cost drug that has been proven effective in preventing the onset of diabetes, according to a UCLA study. The study, published in the peer-reviewed journal Annals of Internal Medicine, found that only 3.7 percent of U.S. adults with pre-diabetes were prescribed metformin during a recent three-year period. Metformin and lifestyle changes both can prevent the onset of diabetes, but people often struggle to adopt healthier habits, according to Dr. Tannaz Moin, the study's lead author and an assistant professor of medicine in the division ...

The international Solar Wind Sherpas team, led by Dr. Shadia Habbal of the University of Hawaii at Manoa Institute for Astronomy, braved Arctic weather to successfully observe the total solar eclipse of March 20 from Longyearbyen on the island of Spitsbergen in the Svalbard archipelago east of northern Greenland. Their preliminary results are being presented Thursday at the Triennial Earth-Sun Summit in Indianapolis, IN. It was no easy feat. Ever-changing weather predictions, subfreezing temperatures of -4 degrees F (-20 C) and the danger from polar bears were some of ...

Silica dust hazards in large gold mines have been well documented, but the situation is far worse in small-scale gold mining according to a new study. The new research in the article "Silica Exposures in Artisanal Small-Scale Gold Mining in Tanzania and Implications for Tuberculosis Prevention" shows that exposures to silica are more than two hundred times greater in small-scale artisanal mines than in larger mines. Hundreds of thousands of miners have already come down with silicosis and rates of tuberculosis (TB) among miners in Africa are approximately 5-6 times higher ...

Pathological gamblers "see" patterns in things that are actually quite random and not really there, to such a degree that they are quite willing to impulsively bet good money on such illusory nonrandomness. This is confirmed by Wolfgang Gaissmaier of the University of Konstanz in Germany and Andreas Wilke of Clarkson University in the USA, leaders of a study in Springer's Journal of Gambling Studies that sheds light on why some people are gamblers and others not. The findings of the study add to a large body of research that suggests that cognitive distortions (or people's ...

Researchers at the Helmholtz Zentrum München now report the discovery of a very unexpected role for one such lncRNA, which they call PARTICLE, in regulating the response of cells to ionizing radiation. Biophysical studies have shown that the damage arising to cells from an exposure to ionizing radiation declines in a linearly manner with decreasing dose, with some damage still occurring even at the lowest doses. This linear no-threshold (LNT) dose-response relationship has been used to extrapolate the risks of low doses of radiation from epidemiological studies that ...

Researchers at the University of Liverpool have found that people who eat different types and brands of commonly available food items, such as pizza, are more likely to overeat than people who tend to consume the same brand. Psychologists from the Universities of Liverpool and Bristol undertook the first study of its kind to look at the effect of the wide variety of types and brands of mass-produced foods on consumption. Importantly. The number of varieties of the same food product that are available to consumers has increased dramatically since the 1970s and the use ...

For the past 50 years, researchers at Sahlgrenska Academy have followed the health of 855 Gothenburg men born in 1913. Now that the study is being wrapped up, it turns out that ten of the subjects lived to 100 and conclusions can be drawn about the secrets of their longevity. Over the past half century, the University Gothenburg has hosted one of the world's first prospective studies of aging. The subjects are 855 Gothenburg men born in 1913. The first surveys were conducted in 1963.Now that it has been determined that ten of the men lived to 100, the study is being ...
