Savitz, MD, of UTHealth Houston reported today in the journal Stem Cells that bone marrow cells used to treat ischemic stroke in an expanded Phase I trial were not only safe and feasible, but also resulted in enhanced recovery compared to a matched historical control group.
Researchers from the Tulane University School of Medicine have discovered that some cancer cells survive chemotherapy by eating their neighboring tumor cells. The study, which will be published September 17 in the Journal of Cell Biology, suggests that this act of cannibalism provides these cancer cells with the energy they need to stay alive and initiate tumor relapse after the course of treatment is completed.
A randomized clinical trial led at Children's Hospital Los Angeles by Leo Mascarenhas, MD, MS, showed first positive results in rhabdomyosarcoma since 1974.
Early rice growers unwittingly gave barnyard grass a big hand, helping to give root to a rice imitator that is now considered one of the world’s worst agricultural weeds. New research from Zhejiang University, the Chinese Academy of Sciences and Washington University in St. Louis provides genomic evidence that barnyard grass (Echinochloa crus-galli) benefited from human cultivation practices, including continuous hand weeding, as it spread from the Yangtze River region about 1,000 years ago.

Scientists at Washington University School of Medicine in St. Louis appear to have solved a decades-long mystery regarding the precise biochemical pathway leading to a fatal genetic disorder in children that results in seizures, developmental regression and death, usually around age 3. Studying a mouse model with the same human illness — called Krabbe disease — the researchers also identified a possible therapeutic strategy.
Researchers have developed a novel way to measure how mechanical fatigue affects biological cells. They also have established the important role of this effect in influencing physical properties of biological cells such as red blood cells (RBCs). This new technique assesses the mechanical integrity and fatigue behavior of RBCs using a general microfluidics method that incorporates amplitude-modulated electro-deformation. This method has important applications for mechanical fatigue studies in conjunction with other microenvironments related to health and materials engineering.

Cancer in the ovaries often metastasizes to the surrounding tissues, but is too small to be detected. Now a label-free microscopy technique is able to identify these regions with great accuracy, enabling early removal of these microscopic malignancies.
Female athletes seek specialty medical treatment later than male athletes for sports-related concussions (SRC), and this delay may cause them to experience more symptoms and longer recoveries. The study raises the question of whether, in youth and high school sports, inequities in medical and athletic trainer coverage on the sidelines are contributing to delayed identification and specialized treatment of concussion for female athletes, leading to more symptoms and longer recovery trajectories.
A source of embarrassment to some, or pure comedy to others, flatulence and the gases of the intestines are increasingly seen as playing an important role in our digestive health.
ST. PETERSBURG, Fla. (September 12, 2019)- A new study from the University of South Florida St. Petersburg and Eckerd College estimates the waters of Tampa Bay contain four billion particles of microplastics, raising new questions about the impact of pollution on marine life in this vital ecosystem.
The fate of the world's coral reefs could depend on how well the sea creatures equip their offspring to cope with global warming.

In a follow-up study conducted in South Africa, Johns Hopkins Medicine researchers say they have evidence that hospital emergency departments (EDs) worldwide may be key strategic settings for curbing the spread of HIV infections in hard-to-reach populations if the EDs jump-start treatment and case management as well as diagnosis of the disease. A report on the findings was published in August in EClinicalMedicine.
Researchers found that a sleep schedule built to resemble a work week disrupted lipid metabolism and feelings of fullness after a meal. One night's recovery sleep helped... but not enough to return metabolism to normal.
People are more likely to blame violent video games as a cause of school shootings by white perpetrators than by African American perpetrators, possibly because of racial stereotypes that associate minorities with violent crime, according to new research published by the American Psychological Association.
A team of researchers, including faculty at Binghamton University, have developed machine learning algorithms which can successfully identify bullies and aggressors on Twitter with 90 percent accuracy.

Scientists obtained a total of 733 pathogen isolates from 171 individual wild Bottlenose dolphins in Florida and found that the overall prevalence of resistance to at least one antibiotic for the 733 isolates was 88.2 percent. Resistance was highest to erythromycin, followed by ampicillin. It is likely that these isolates from dolphins originated from a source where antibiotics are regularly used, potentially entering the marine environment through human activities or discharges from terrestrial sources.
