Oncotarget published "[18F]FDG and [18F]FES positron emission tomography for disease monitoring and assessment of anti-hormonal treatment eligibility in granulosa cell tumors of the ovary" which reported that the authors evaluated 22 PET/CTs from recurrent Anti-hormonal granulosa cell tumors (AGCT) patients to determine tumor FDG and FES uptake by qualitative and quantitative analysis.
BINGHAMTON, N.Y. -- Women's mental health likely has a higher association with dietary factors than men's, according to new research from Binghamton University, State University of New York.
Lina Begdache, assistant professor of health and wellness studies at Binghamton University, had previously published research on diet and mood that suggests that a high-quality diet improves mental health. She wanted to test whether customization of diet improves mood among men and women ages 30 or older.
Microphones are perhaps the most common electronic sensor in the world, with an estimated 320 million listening for our commands in the world's smart speakers. The trouble is that they're capable of hearing everything else, too.
But now, a team of University of Michigan researchers has developed a system that can inform a smart home--or listen for the signal that would turn on a smart speaker--without eavesdropping on audible sound.
Scientists have observed for the first time what it looks like in the key memory region of the brain when a mistake is made during a memory trial. The findings have implications for Alzheimer's disease research and advancements in memory storage and enhancement, with a discovery that also provides a view into differences between the physiological events in the brain during a correct memory versus a faulty one.
The study was published today in the journal Nature Communications.
Most fish rely on water to feed, using suction to capture their prey. A new study, however, shows that snowflake morays can grab and swallow prey on land without water thanks to an extra set of jaws in their throats.
After a moray eel captures prey with its first set of jaws, a second set of "pharyngeal jaws" then reaches out to grasp the struggling prey and pull it down into the moray's throat. Rita Mehta, an associate professor of ecology and evolutionary biology at UC Santa Cruz, first described this astonishing feeding mechanism in a 2007 Nature paper.
Propylene oxide (PO) is one of the important propylene derivatives with high reactivity, which is used extensively as raw material for the manufacture of numerous commercial chemicals. The titanosilicate-catalyzed hydrogen peroxide propylene oxide process (HPPO) is considered to be most advantageous because it is highly economical and ecofriendly, giving only H2O as the theoretical byproduct and achieving high PO selectivity under mild reaction conditions. The industrial HPPO process is generally carried out in a fixed-bed reactor using the shaped titanosilicate catalysts.
The geometric isolation of metal species in single-atom catalysis (SACs) not only maximizes the atomic utilization efficiency, but also endows SACs with unique selectivity in various transformations.
The coordination environment of isolated metal atoms in SACs determines the catalytic performance. However, it remains challenging to modulate the coordinative structure while still maintain the single-atom dispersion.
UPTON, NY--Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have published the first detailed atomic-level model of the SARS-CoV-2 "envelope" protein bound to a human protein essential for maintaining the lining of the lungs. The model showing how the two proteins interact, just published in the journal Nature Communications, helps explain how the virus could cause extensive lung damage and escape the lungs to infect other organs in especially vulnerable COVID-19 patients.
An unprecedented analysis of almost 10,000 Harmful Algal Bloom (HAB) events worldwide over the past 33 years was launched today by UNESCO's Intergovernmental Oceanographic Commission.
The first-ever global statistical analysis examined ~9,500 HABs events over 33 years and found that the harm caused by HABs rises in step with growth of the aquaculture industry and marine exploitation and calls for more research on linkages.
Durham, NC - Critically ill COVID-19 patients treated with non-altered stem cells from umbilical cord connective tissue were more than twice as likely to survive as those who did not have the treatment, according to a study published today in STEM CELLS Translational Medicine.
The clinical trial, carried out at four hospitals in Jakarta, Indonesia, also showed that administering the treatment to COVID-19 patients with an added chronic health condition such as diabetes, hypertension or kidney disease increased their survival more than fourfold.
The incidence rate of lung adenocarcinoma (LUAD) is increasing gradually and the mortality is still high. Recent advances in the genomic profile of LUAD have identified a number of driver alterations in specific genes, enabling molecular classification and targeted therapy accordingly. However, only a fraction of LUAD patients with those driver mutations could benefit from targeted therapy, and the remaining large numbers of patients were unclassified. RNA editing events are those nucleotide changes in the RNA.
Susceptibility of COPD patients to heart rate difference associated with exposure to metals in PM2.5
Epidemiological and toxicological studies indicate that the adverse outcomes of PM2.5 exposure associated closely with the chemical composition in PM2.5. Metals in PM2.5 are highly concerned for their induced disruption of iron homeostasis in the lung and following oxidative stress, which is one of the key mechanisms underlying the cardiovascular autonomic dysfunction of PM2.5 exposure. However, there is no clear evidence on whether COPD patients are more susceptible to cardiovascular autonomic dysfunction associated with exposure to metals in ambient PM2.5 than individuals without COPD.
Supermassive black holes (SMBH) occupy the center of galaxies, with masses ranging from one million to 10 billion solar masses. Some SMBHs are in a bright phase called active galactic nuclei (AGN).
AGNs will eventually burn out since there is a maximum mass limit for SMBHs; scientists have long since pondered when that will be.
Tohoku University's Kohei Ichikawa and his research group may have discovered an AGN towards the end of its life span by accident after catching an AGN signal from the Arp 187 galaxy.
A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR) in Pune, and the Raman Research Institute (RRI), in Bangalore, has used the Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen gas content of galaxies 9 billion years ago, in the young universe. This is the earliest epoch in the universe for which there is a measurement of the atomic hydrogen content of galaxies.
Decades of research has revealed the remarkable morphological adaptations of sea snakes to aquatic life, which include paddle-shaped tails, salt-excreting glands, and the ability to breathe through their skin.
In a new study published in Biological Journal of the Linnean Society, researchers at the University of Adelaide detail the enlarged touch receptors that evolved in male turtle-headed sea snakes (Emydocephalus annulatus), to help them locate and court females in aquatic environments.
