Barcelona-- First line pembrolizumab monotherapy provides durable long-term overall survival benefit compared to chemotherapy, according to data presented today by Dr. M. Reck, Lung Clinic Grosshansdorf, Airway Research Center North (ARCN), Member of the German Center for Lung Research Grosshansdorf/Germany. The presentation was made at the IASLC 2019 World Conference on Lung Cancer, hosted by the International Association for the Study of Lung Cancer.
An artificial intelligence tool - which analyzed 28 physical and molecular measures, all but one from blood samples - confirmed with 77 percent accuracy a diagnosis of posttraumatic stress disorder (PTSD) in male combat veterans, according to a new study.
NASA's Aqua satellite passed over the Central Atlantic Ocean and provided a visible view of Tropical Storm Gabrielle that helped pinpoint its strongest side.
On Sept. 8, 2019 at 2:35 p.m. EDT (1635 UTC), the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite provided a visible image of Gabrielle that showed strongest thunderstorms northeast of the center.
The MODIS image also showed that there were also fragmented bands of strong thunderstorms south and southwest of the center.
"Lingering ash." That's what the U.S. Forest Service calls the relatively few green and white ash trees that survive the emerald ash borer onslaught. Those trees do not survive by accident, and that may save the species, according to Penn State researchers, who conducted a six-year study of ash decline and mortality.
The research shows some ash trees have varying degrees of resistance to the strangely beautiful, invasive beetle from Asia. The study is unique because it took place at a plantation of ash trees planted on Penn State's University Park campus in the mid-1970s.
Bottom Line: Reporting more positive childhood experiences was associated with a lower likelihood of adult depression or poor mental heath, or both, and a greater likelihood of adults reporting social and emotional support even after accounting for adverse childhood experiences in this observational study based on survey data representative of the entire population of adults in Wisconsin in 2015.
Scientists have greatly extended the amount of time human livers can be stored for transplantation by modifying a previous protocol to extend the viability of rat livers. Previously, human livers were only viable for an average of nine hours, but the new method of preservation maintains liver tissue for up to 27 hours, giving transplant doctors and patients a much longer timeframe to work with.
Although predisposing processes occur earlier, schizophrenia breaks out at young adulthood, suggesting it might involve a pathological transition during late brain development in predisposed individuals. Using a genetic mouse model of schizophrenia, researchers from the Caroni group at the Friedrich Miescher Institute for Biomedical Research (FMI) showed that, like in patients, characteristic network and cognitive deficits only emerge in adult mice.
The lightning season in the Southeastern U.S. is almost finished for this year, but the peak season for the most powerful strokes of lightning won't begin until November, according to a newly published global survey of these rare events.
A research team led by the University of Basel and the University of Montreal examined how the ongoing climate warming affects the "behavior" of lakes. The researchers found out why, in near-bottom waters, lakes may even cool down despite warming at the surface, and what the consequences are for the production and emission of greenhouse gases. The results of the study were published in the most recent edition of the journal Limnology and Oceanography Letters.
Although various image-based central position estimation (termed "centroid fitting") methods such as 2D Gaussian fitting methods have been commonly used in single-molecule localization microscopy (SMLM) to precisely determine the location of each fluorophore, it is still a challenge to improve the single-molecule lateral localization precision to molecular scale (In a study published online in Nature Methods, Prof. XU Tao and Prof.
Dogs in tropical Africa run the risk of contracting canine trypanosomosis if they are bitten by bloodsucking tsetse flies carrying trypanosomes - microscopic, single-celled organisms found in the bloodstream. In dogs, this disease runs a severe course and is often fatal; "white eyes" or corneal cloudiness is one of the characteristic and obvious signs of the disease.
Optical microresonators convert laser light into ultrashort pulses travelling around the resonator's circumference. These pulses, called "dissipative Kerr solitons", can propagate in the microresonator maintaining their shape.
In a large study, German scientists have shown that physical fitness is associated with better brain structure and brain functioning in young adults. This opens the possibility that increasing fitness levels may lead to improved cognitive ability, such as memory and problem solving, as well as improved structural changes in the brain. This work is presented for the first time at the ECNP Congress in Copenhagen, with simultaneous publication in the peer-reviewed journal Scientific Reports*.
St. Paul, MN (September 2019)--Powdery mildew is a common fungal disease that infects many plants around the world, absorbing their nutrients and weakening or even killing them. In turn, powdery mildews are often attacked in the field by even smaller mycoparasites (fungi that feed on other fungi).
A new chemistry method from scientists at Scripps Research in La Jolla, California, greatly simplifies the creation of an important class of compounds called hindered ethers, which are integral to many drugs and commercial products. Hindered ethers are often coveted for their special properties, but until now have required laborious methods to synthesize.
