HOUSTON - Cytokine-activated natural killer (NK) cells derived from donated umbilical cord blood, combined with an investigational bispecific antibody targeting CD16a and CD30 known as AFM13, displayed potent anti-tumor activity against CD30+ lymphoma cells, according to a new preclinical study from researchers at The University of Texas MD Anderson Cancer Center.
Boston - Pregnant women with symptomatic COVID-19 have a higher risk of intensive care unit admissions, mechanical ventilation and death compared to non-pregnant reproductive age women. Increases in preterm birth and still birth have also been observed in pregnancies complicated by the viral infection. The Centers for Disease Control and Prevention (CDC) recommended that people who are pregnant may choose to be vaccinated at their own discretion with their healthcare provider.
Despite having been driven nearly to extinction, the California condor has a high degree of genetic diversity that bodes well for its long-term survival, according to a new analysis by University of California researchers.
Nearly 40 years ago, the state's wild condor population was down to a perilous 22. That led to inbreeding that could have jeopardized the population's health and narrowed the bird's genetic diversity, which can reduce its ability to adapt to changing environmental conditions.
TORONTO, ON - A team of evolutionary biologists from the University of Toronto has shown that Anolis lizards, or anoles, are able to breathe underwater with the aid of a bubble clinging to their snouts.
Anoles are a diverse group of lizards found throughout the tropical Americas. Some anoles are stream specialists, and these semi-aquatic species frequently dive underwater to avoid predators, where they can remain submerged for as long as 18 minutes.
The stock market is a staple of business news, but it is unclear how meaningful stock prices are to the larger economy. Do changes in stock prices directly affect shorter-term consumption, or are they just leading indicators for subsequent economic activity? The U.S. Federal Reserve, for its part, usually seems to act as if stock-based wealth does help drive spending and employment. But is this correct?
PHOENIX, Ariz. -- May 13, 2021 -- In the largest study of the associations between smoking and cardiovascular disease on cognitive function, researchers at the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, found both impair the ability to learn and memorize; and that the effects of smoking are more pronounced among females, while males are more impaired by cardiovascular disease.
The results appear today in the journal Scientific Reports.
College Park, Md. - Companies have often considered app adoption among their customers to have a positive impact on customer spending. According to new research from marketing professor P.K. Kannan at the University of Maryland's Robert H. Smith School of Business, higher app adoption among hotel chains could be linked to lower spending among lower-level loyalty customers, who are more likely to use apps to get the best deals.
Viruses require the resources of an infected cell to replicate and then infect further cells, and transfer to other individuals. One essential step in the viral life cycle is the production of new viral proteins based on the instructions in the viral RNA genome. Following these construction plans, the cell's own protein synthesis machine, called the ribosome, produces the viral proteins.
First co-author, Junior Research Associate of the Rheological and Thermochemical Research Lab Richard Djimasbe, comments, "To obtain bitumen as a half-solid product from heavy oil, you have to extract light fractions, and the rest is non-oxidized bitumen. Because of the relatively low ratio of light fractions in heavy oil, it's a simple and cheap way of bitumen production. The method allows for rational use of both heavy oil and light oil."
A large-scale randomised trial of annual screening for ovarian cancer, led by UCL researchers, did not succeed in reducing deaths from the disease, despite one of the screening methods tested detecting cancers earlier.
Results from the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) have been published in a report in the medical journal The Lancet.
AURORA, Colo. (May 13, 2021) - Researchers at the University of Colorado College of Nursing found that many of its graduate students suffered from increased stress after the onset of the COVID-19 pandemic. More than 90% of students worked during the pandemic on average nearly 34 hours per week. Juggling school, a varied work-load and changes to their schedules all significantly influenced stress levels.
BOSTON - B cells are the immune cells responsible for creating antibodies, and most B cells, known as B2 cells, produce antibodies in response to a pathogen or a vaccine, providing defense and immunity against infections. But a small subset of long-lived B cells, known as B1 cells, are quite different from their short-lived cousins, the B2 cells. Instead of producing antibodies in response to invaders, they spontaneously make antibodies that perform vital housekeeping functions, such as removing waste like oxidized LDL cholesterol from the blood.
LA JOLLA, CA--A family of proteins that sense mechanical force--and enable our sense of touch and many other important bodily functions--also are essential for proper root growth in some plants, according to a study led by scientists at Scripps Research and Howard Hughes Medical Institute (HHMI).
The discovery, published in the points to an ancient evolutionary origin for the PIEZO proteins, which until now had mainly been characterized in animals. This advance in basic biology may also lead to new strategies for improving crop yields, the researchers say.
Bethesda, MD (May 14, 2021) -- Despite the fact that certain racial and ethnic minorities get pancreatic cancer more often, are diagnosed at a younger age and die sooner, clinical trials fail to include representative proportions of non-White patients at every phase of study, according to research that was selected for presentation at Digestive Disease Week® (DDW) 2021.
Researchers from Monash University, Queensland University of Technology, and Capital University of Economics and Business published a new paper in the Journal of Marketing that examines the effects of imaginative product displays in retail stores on customers' purchase behavior.
The study, forthcoming in the Journal of Marketing, is titled "Gimmicky or Effective? The Effects of Imaginative Displays on Customers' Purchase Behavior" and is authored by Hean Tat Keh, Di Wang, and Li Yan.
