SAN DIEGO, April 26, 2018 - A significant update to the PROGRESS-CTO (PROspective Global Registry for the Study of Chronic Total Occlusion Intervention) International Registry was presented today as late-breaking clinical science at Society for Cardiovascular Angiography and Interventions (SCAI) Scientific Sessions 2018. The study includes results of Chronic Total Occlusion Percutaneous Intervention (CTO PCI) for more than 3,000 patients across 20 centers in the United States, Europe, and Russia.
Irvine, Calif., April 27, 2018 - Climate models predict that an increase in greenhouse gases will dry out the Amazon rainforest in the future while causing wetter conditions in the woodlands of Africa and Indonesia. Researchers at the University of California, Irvine and other institutions have identified an unexpected but major factor in this worldwide precipitation shift: the direct response of the forests themselves to higher levels of carbon dioxide.
University of Colorado Cancer Center researchers recently completed the largest-ever study of thyroid cancer genetics, mining the data of 583 patient samples of advanced differentiated thyroid cancer and 196 anaplastic thyroid cancers. In addition to identification of specific genes that may drive these cancers and thus provide attractive targets for treatment, the researchers found that in several samples of advanced differentiated and anaplastic thyroid cancer (the most aggressive and dangerous forms of the disease), mechanisms meant to repair faulty DNA had been broken.
Irvine, Calif., April 26, 2018 -- Coral reef bleaching is stark evidence of the damage being inflicted by global climate change on marine ecosystems, but a research team led by scientists at the University of California, Irvine has found some cause for hope. While many corals are dying, others are showing resilience to increased sea surface temperatures, pointing to possible clues to the survival and recovery of these vitally important aquatic habitats.
A Northwestern University and Argonne National Laboratory research team has developed an exceptional next-generation material for nuclear radiation detection that could provide a significantly less expensive alternative to the detectors now in commercial use.
Where do seabirds go when their nesting colony is buried by a volcano? In 2008, the eruption of the Kasatochi volcano in the Aleutian archipelago provided a rare opportunity to track how the island's Crested and Least auklet populations responded when their nesting colony was abruptly destroyed. As a new study from The Auk: Ornithological Advances shows, the birds were surprisingly adaptable, establishing a new colony on freshly created habitat nearby in only four years.
Today's shifting environmental conditions are creating an uncertain future for many top predators in marine ecosystems, but to protect the key habitat of a species, you first have to know where that habitat is and what threats might be affecting it. A new study from The Condor: Ornithological Applications looks at where New Zealand's endangered Westland Petrel forages during its breeding season and shows that its range overlaps more with trawl fishing activity than conservationists realized.
Deep-diving whales and other marine mammals can get the bends--the same painful and potentially life-threatening decompression sickness that strikes scuba divers who surface too quickly. A new study offers a hypothesis of how marine mammals generally avoid getting the bends and how they can succumb under stressful conditions.
How do you boost soil water content and soil health without irrigating? Best cover it with a layer of straw, a new study concludes.
Farmers in China's Loess Plateau have for decades used both plastic and straw as a soil cover, or mulch, between crops. Much of the region's agriculture, of which corn is a large part, is dryland; the crops depend solely on seasonal rainfall. Dry spells can hurt crop growth and yield. So the two mulches--both inexpensive and readily available--are used to stop water loss from evaporation and keep soil warm.
An international team including researchers from King's College London have found physical activity can protect against the emergence of depression, regardless of age and geographical region.
The researchers from Brazil, Belgium, Australia, USA, UK and Sweden pooled data from 49 unique cohort studies of people free from mental illness that examined if physical activity is associated with a decreased risk of developing depression.
As concerns about privacy increase for people using mobile apps, users' trust and engagement may hinge on perceptions about how the app uses their data and whether it seeks user input before delivering personalized services, according to researchers. However, their reactions may also depend on how familiar a user is with technology, they added.
Drinking alcohol may be linked to pre-menstrual syndrome, or PMS for short, suggests a pooled analysis of published study data in the online journal BMJ Open.
Based on the global prevalence of alcohol drinking and their study findings, the Spanish researchers estimate that around one in 10 cases (11%) might be linked to alcohol intake.
Premenstrual syndrome includes any or all of mood swings, tender breasts, food cravings, fatigue, irritability and depression. Its severity varies from woman to woman.
New research from King's College London shows that lonely young adults are more likely to experience mental health problems and more likely to be out of work than their peers. The study, published today in Psychological Medicine, gives a detailed snapshot of the lives of lonely 18-year-olds and shows how loneliness goes hand-in-hand with a wide range of problems in health and wellbeing.
In an effort to improve the quality of biodiversity records, the Atlas of Living Australia (ALA) and the Global Biodiversity Information Facility (GBIF) use automated data processing to check individual data items. The records are provided to the ALA and GBIF by museums, herbaria and other biodiversity data sources.
Of the more than 38 million Americans who experience migraine headaches, 28 million are women. Compared to men, women also experience more frequent and severe migraines and don't respond as well to drug treatments. Findings from a new study conducted in rats reveal that females may be more susceptible to migraines and less responsive to treatment because of the way fluctuations in the hormone estrogen affect cells in the brain.
