DENVER - May 24, 2016 - Simultaneous pre-treatment with antihistamines that block both the H1 and H4 antihistamine receptors suppressed the gastrointestinal symptoms of food allergy in mice, according to researchers at National Jewish Health. The findings, published online in the journal Allergy, provide new insight into the development of food allergy and suggest potential therapies for prevention and treatment of food allergy.

SAN FRANCISCO - May 25, 2016 - Researchers studying babies with a Zika virus-related birth defect say they have found previously unreported eye problems possibly linked to the virus that could result in severe visual impairment. In three Brazilian infants with microcephaly, the researchers observed retinal lesions, hemorrhaging and abnormal blood vessel development not noted before in relation to the virus.
Among nearly 35,000 initially healthy women who were followed-up for about 20 years, those with new-onset atrial fibrillation had an increased risk of cancer, according to a study published online by JAMA Cardiology.
Ottawa, May 25, 2016 - A new study from the University of Ottawa Heart Institute (UOHI), in collaboration with the Institute for Clinical Evaluative Sciences (ICES), has established that greater adoption of hospital-initiated tobacco cessation interventions improve patient outcomes and decrease further healthcare utilization. The study is published today in the British Medical Journal's Tobacco Control.
The UK Lung cancer screening trial (UKLS) has been successfully completed and demonstrated that patients with a high risk of developing lung cancer can be identified with early stage disease and have up to a 73% chance of surviving for five years or more. The UKLS trial was conducted by experts in the University of Liverpool.
NORTH GRAFTON, Mass. (May 25, 2016) - A veterinarian sees a canine patient with severe rib and head injuries whose cause of injury is unknown. Without having witnessed the incident, how can the veterinary professional distinguish an accident from abuse?
Inflammatory bowel diseases, or IBD, such as ulcerative colitis, are intractable diseases with unknown etiology. The number of patients with IBD in Japan has tremendously increased in recent years. However, there are no definitive treatments at present. Recently, the dysfunction of the intestinal mucosal barrier has been thought to be one of the causes for IBD. Indeed, in genetically-modified mice in which the mucosal barrier is defective, intestinal bacteria invade the colonic mucosa, and this causes high susceptibility to intestinal inflammation.
Plants 'talk' to each other through mycorrhizal networks, but can we eavesdrop on what plants are talking about? They can sense chemicals through their roots, but can we sensibly talk about how they 'search' for food? While a lot is already known about plant perception, our ecological understanding of plants has largely focused on seeing plants as the sum of a series of building blocks or traits.
Bacteria use a form of "social media" communication called quorum sensing to monitor how many of their fellow species are in the neighborhood, allowing them to detect changes in density and respond with changes in collective behavior. Because of the importance of quorum sensing to the behavior of disease-causing bacteria like Vibrio cholerae, the cause of the deadly disease cholera, understanding how it works has the potential to allow us to disrupt it for therapeutic purposes.
More than half of Europeans now think that e-cigarettes are harmful--a proportion that has nearly doubled in two years--show the latest results of a European Union (EU)-wide survey, published online in the journal Tobacco Control.
Yet use of these devices across member states has continued to surge within the same timeframe, the findings show.
Offering DIY sampling kits for HIV using online dating apps and social media targeting gay men, successfully unearths previously undiagnosed cases of the infection, reveals an evaluation of the first large-scale dedicated service in the UK, published online in the journal Sexually Transmitted Infections.
Furthermore, this approach catches most men before their infection has reached an advanced stage, so making it easier and potentially cheaper to treat effectively.
There is 'suggestive evidence' for a link between air pollution and a heightened risk of stillbirth, indicates a summary of the available data, published online in Occupational & Environmental Medicine.
An estimated 2.6 million children worldwide were stillborn at 28 weeks or more in 2015, with the wide geographical variation in prevalence suggesting that most of these deaths were preventable, say the study authors.
Passed in 2016 in the United Kingdom and due to come into force on 26 May, the Psychoactive Substances Act bans all new psychoactive substances (NPS) except those specifically exempted, such as alcohol and tobacco. The Act has attracted much criticism from scientists and experts. But what better alternative exists? The scientific journal Addiction has today [25 May] published the opening statement in a debate by leading addiction researchers from around the globe.
Urine tests should not be used to measure dehydration among the elderly - according to new research from the University of East Anglia (UEA).
Water-loss dehydration happens when people don't drink enough fluid. Urine tests are widely used by medics, nurses and other health professionals to screen for water-loss dehydration among older people.
But new research published today reveals that the diagnostic accuracy of urine tests is too low to be useful and that the tests should not be used to indicate hydration status in older people.
A group of leading academics from the School of Public Health at Imperial College London says the UK must remain in the EU in order to protect the health of UK residents. Also at risk following a vote to leave the EU, says the group, would be the recruitment of doctors and healthcare workers to the NHS, medical research and teaching and the continued world-leading status of the top UK universities.
