The newly published thesis research of University of Guam Master of Environmental Science graduate Benjamin Deloso now adds to the body of knowledge about asexual propagation of the most endangered plant group in the world, cycads. His work was part of a set of UOG studies, all focused on improving the asexual propagation of cycads, published in the September 2020 issue of HortScience, one of the oldest horticultural journals in the United States.
We employ our cognitive skills daily to assimilate and process information. A new empirical study shows that we do better at this task than those born a century ago. But cognitive capacity still begins to stagnate at around the age of 35.
TAMPA, Fla. -- Prostate cancer is the most common type of cancer among American men after skin cancer, but the disease does not affect all races equally. African American men are nearly two times more likely to develop prostate cancer, and more often have an aggressive form of the disease that grows and spreads quickly. They are also two times more likely to die from prostate cancer compared to white men. While the health care community is aware of this disparity, little is known about why prostate cancer affects African American men differently.
BUFFALO, N.Y. -- Chemicals that haven't been manufactured in the U.S. for years or even decades are still turning up in the bodies of migratory terns in the Great Lakes region, a new study finds.
The research focused on three types of compounds: polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and the breakdown products, called metabolites, of dichlorodiphenyltrichloroethane (DDT).
During cell division specific target proteins have to be turned over in a precisely regulated manner. To this end specialized enzymes label the target proteins with signaling molecules. However, the enzymes involved in this process can also label themselves, thus initiating their own degradation. In a multidisciplinary approach, the researchers identified a mechanism of how enzymes can protect themselves from such self-destruction and maintain sufficient concentrations in the cell. These results have been published in the latest issue of Science Signaling.
According to the Mayo Clinic, about 15% of couples are infertile, and male infertility plays a role in over one-third of these cases. Often, problems with sperm development are to blame. Now, researchers reporting in ACS Nano have found a way to deliver a protein important for sperm cell production directly to mouse testicles, where it restored normal sperm development and allowed previously infertile mice to father pups.
Wrong-site surgery, medication errors, and fires in operating rooms can be devastating for patients, providers, hospitals, and insurance companies alike. In risk management, these are referred to as sentinel adverse events. Determining the true causes of these events can help hospitals improve their processes, leading to large impacts on costs and outcomes of care.
PROVIDENCE, R.I. [Brown University] -- As researchers and medical professionals work to develop new treatments for cancer, they face a variety of challenges. One is intratumor heterogeneity -- the presence of multiple kinds of cancer cells within the same tumor. Often, these "mosaic" tumors include cells, such as polyploidal giant cancer cells, that have evolved to become aggressive and resistant to chemotherapy and radiation.
Results from a new study published in Alzheimer's & Dementia support emerging evidence suggesting that noise may influence individuals' risk of developing dementia later in life.
Numerous studies have examined interventions aimed at preventing violence against children. A recent analysis reveals various gaps not adequately addressed by these studies.
The cover for issue 31 of Oncotarget features Figure 4, "Concentration dose-response curves of sirolimus effect [55 nM–1 nM] on the number of cells per surviving colony in U2OS cell line after 2 weeks exposure," by Vasuri, et al.
(Boston)-- Although frequently used to treat painful osteoarthritis of the hip and knee, intra-articular corticosteroid (IACS) injections remain controversial. Questions about whether damage to joints occurs as a result of these injections, which are performed thousands a time each day, persist.
WASHINGTON, October 20, 2020 -- As the coronavirus has affected more than 30 million people globally, researchers have increasingly focused on the extent to which airborne respiratory droplets carrying the virus travel and contaminate the air after an infected person coughs.
More than 480,000 U.S. deaths per year, as well as diseases affecting 16 million living Americans, can be attributed to cigarette smoking, according to the Centers for Disease Control and Prevention. In particular, this behavior continues to be overrepresented among those with mental illness, substance use disorders, and socioeconomic disadvantage.
With cases increasing in the UK and elsewhere, and winter approaching, there is an urgent need for reliable models that predict the likely course of Covid-19, to support decisions about shielding, hospital admission, treatment, and vaccinations.
