ATLANTA, August 4, 2023 — In new findings from researchers at the American Cancer Society (ACS), non-Hispanic Black individuals diagnosed with a second primary cancer (SPC) experienced 21% higher cancer-related death rates and 41% higher cardiovascular-related death rates compared with their non-Hispanic White counterparts. The study also showed that Hispanic individuals diagnosed with a second primary cancer also experienced 10% higher cancer-related death rates compared with their non-Hispanic White counterparts, but 10% lower cardiovascular-related death rates. The paper was published ...

Ishikawa, Japan -- Liquid metals (LM) such as pure gallium (Ga) and Ga-based alloys are a new class of materials with unique physicochemical properties. One of the most prominent applications of LMs is photothermal therapy against cancer, in which functional LM nanoparticles convert light energy to heat energy, thus killing cancerous cells. LM-based phototherapy is superior to traditional cancer therapy owing to its high specificity, repeatability, and low side effects. In a new cutting-edge study, Associate Professor Eijiro Miyako and his colleagues from Japan Advanced Institute of Science and Technology (JAIST) synthesized multifunctional Ga-based nanoparticles that combine cancer ...

Breastfeeding for six months or more appears to reduce the risk of cardiovascular problems developing in mothers for at least three years after delivery, a new South Australian study has found.    The surprising cardio-metabolic benefit for maternal health is particularly important for women who experienced a complicated pregnancy, which can increase their chance of developing cardiovascular disease (CVD) later in life.    The new results – published this month in the International Breastfeeding Journal by experts from the University of Adelaide ...

Patient-reported outcome (PRO) data are collected in oncology trials to determine patients' perspectives of cancer treatment - unfortunately often too briefly, for example only up to the point when an x-ray shows tumour growth and treatment is discontinued. As a result, it is not possible, for example, to reliably assess the impact on patients' lives of disease progression seen on X-rays or the long-term side effects of cancer treatment. The reasons given for this are organizational difficulties or patients’ lack of interest in long-term follow-up. ...

A subpolar species associated with Atlantic water expanded far into the Arctic Ocean during the Last Interglacial, analysis of microfossil content of sediment cores reveals. This implies that summers in the Arctic were ice free during this period. The findings are published in Nature Geoscience. Arctic sea ice, an important component of the Earth system, is disappearing fast under climate warming. Summer sea ice is anticipated to vanish entirely within this century. To gain a deeper understanding of the climate dynamics in a world without Arctic sea ice, researchers have turned to analogues from the geological past. ”The Last Interglacial, between ...

For several years now, women have been voting more left-wing than men. This trend first appeared in the 2017 German general election and intensified in 2021. This is shown by a study carried out by the sociologist Dr Ansgar Hudde from the Institute of Sociology and Social Psychology at the University of Cologne (UoC). The trend is most evident among the youngest voters aged 18 to 24: In this group, the Greens, the Left and the Social Democrats (SPD) are much more popular among women than among men; the radical right-wing AfD and, above all, the economically liberal FDP are much more popular among men. The Christian ...

Okazaki, Japan – Although you might never have consciously considered it, it’s very likely that when you receive a reward, part of the value that you place on it depends on what other people have received as similar rewards. In a recent study published in Nature Communications, Japanese researchers have identified an important brain circuit for this specific process. Although researchers have identified the brain regions that are important for deciding the value of a reward in relation to those of others (a process the authors termed ‘socially subjective reward valuation’), the connections between these regions have never been ...

On June 20, the American Society for Biochemistry and Molecular Biology submitted public hearing testimony to the Department of Education expressing concerns about the growing burden of student loan debt. The society called for expanding debt-relief programs across all educational levels and allowing postdoctoral researchers to defer loan payments until after completion of their training. “We are in the midst of a student debt crisis, and it's hurting the research enterprise and more importantly, the next generation of scientists,” Sarina Neote, ASBMB public affairs director, said. “The average student ...

Azide compounds play a pivotal role for subsequent synthesis of organonitrogens such as amines and triazoles that are essential compounds in organic and materials chemistry. Triazoles that can be synthesized by the ‘click’ reaction have attracted attention in the development of pharmaceuticals and other industries. However, the azido groups are electrophilic and are susceptible to various nucleophiles such as carbanions. This poses a significant challenge for the synthesis of carbanions having azido groups. To this end, a team of researchers from Japan, led by Associate Professor Suguru ...

A multidisciplinary study led by scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) presents a new method for assessing the structural and electrophysiological changes, called atrial remodeling, produced in the heart of patients with atrial fibrillation, one of the most frequent forms of cardiac arrhythmia. The new diagnostic method is based on the simultaneous assessment of electrical and mechanical (contractile) activity in the heart atria during atrial fibrillation. The study is published in Nature Communications (DOI 10.1038/s41467-023-40196-y). Study leader David Filgueiras explained that, until now, “this was an unmet challenge,” because, on the one ...

A study from Ann & Robert H. Lurie Children’s Hospital of Chicago has shown that prenatal diagnosis, or diagnosis before a baby is born, is associated with earlier surgery for babies with congenital heart defects, the most common birth defects affecting nearly 1% of all live births. The association was demonstrated for critical defects (when heart surgery is required before the infant leaves the hospital) and certain types of noncritical defects, which constitute about 75% of all congenital heart defects. The benefits of prenatal ...

Researchers at Queen Mary University of London’s Precision Healthcare Research Institute (PHURI) and the Berlin Institute of Health (BIH) at Charité – Universitätsmedizin Berlin have identified the genetic causes of Raynaud’s phenomenon. Their findings, published today in Nature Communications, could lead to the first effective treatments for people with Raynaud’s. Raynaud’s phenomenon (RP) is a heritable condition that affects blood circulation. It’s a vasopastic condition, which means ...

Between 7% and 15% of people in North America, between 5% and 9% of people in Europe, and between 1% and 5% of people in Asia suffer from kidney stones. Common symptoms are severe pain, nausea, vomiting, fever, chills, and bloody urine. But kidney stones don’t just reduce the quality of life: in the long run, they may lead to infections, swollen kidneys (hydronephrosis), renal insufficiency, and end-stage renal disease. Known risk factors for developing kidney stones include being an adult male, obesity, chronic diarrhea, dehydration, and having inflammatory bowel disease, diabetes, or gout. Now, a ...

Obesity, a major risk factor for various lifestyle diseases such as diabetes and hypertension has become widespread worldwide, inherently demanding innovative solutions to combat it. A multi-institutional research group led by Associate Professor Akiko Kojima of the Graduate School of Human Life and Ecology at Osaka Metropolitan University, has made significant progress in the fight against obesity. The group had previously conducted a study on the effects of the extract of Mallotus furetianus (MFE), a tropical plant native to Hainan Island, China, on the prevention of fatty liver, but the antiobesity effects of MFE and its mechanisms had not been ...

In a study published today in Cell, one of the most prominent peer-reviewed scientific journals in the field of Biochemistry & Molecular Biology, scientists from the National University of Singapore (NUS) and Imperial College London have discovered a new way by which bacteria transmit their genes, enabling them to evolve much faster than previously understood. Led by Assistant Professor John Chen from the Department of Microbiology and Immunology and the Infectious Diseases Translational Research Programme at the NUS Yong Loo Lin School of Medicine (NUS Medicine), ...

Understanding the ionosphere high in the Earth's atmosphere is important due to its effects on communications systems, satellites and crucial chemical features including the ozone layer. New insights into the activity of high energy electrons have come from a simulation study led by geophysicist Yuto Katoh at Tohoku University, reported in the journal Earth, Planets and Space. "Our results clarify the unexpected role of the geomagnetic field surrounding the Earth in protecting the atmosphere from high energy electrons," says Katoh. The ionosphere is a wide region between roughly ...

Function and form are deeply intertwined in biology. Knowing how organisms grow, adapt and reproduce requires understanding their physical structures. Hence the transformative power of the microscope across the past four centuries of science. Microscopy, or the field of microscope use, can now reveal the tiniest of structures through techniques such as microcrystal electron diffraction, or MicroED. Instead of passing light through a cell like an optical microscope, MicroED bombards crystalline samples with a stream of electrons to produce detailed information about their atomic configuration. “The method was developed ...

The research findings were published in Nature Aging (IF=16.6) ...

Leesburg, VA, August 4, 2023—An accepted manuscript published in the American Journal of Roentgenology (AJR) found that deploying a radiomic-based model with T2-weighted MRI data could increase diagnostic accuracy for pediatric Crohn disease (CD). Noting that ileal-wall radiomic features were strongly predictive of CD—and that model performance improved when ensembled with clinical data—“a radiomic machine learning model predicted CD diagnosis with better performance than two of three expert radiologists,” wrote corresponding author and AJR Pediatric Imaging Section Editor Jonathan R. Dillman, MD, MSc. Dillman et al.’s manuscript ...

Childhood trauma, such as abuse, emotional neglect, and exposure to domestic violence, may heighten a woman’s subsequent risk of pregnancy complications, and of giving birth to a low birthweight or premature baby, finds a pooled data analysis of the available evidence, published in the open access journal BMJ Open.  The risks of pregnancy related diabetes, high blood pressure, depression/anxiety and of giving birth to underweight and or premature babies may all be significantly higher, the analysis suggests. While previously ...

The use of essential peppermint oil aromatherapy may ease pain severity after open heart surgery and enhance sleep quality as well, suggest the results of a small comparative clinical trial, published online in the journal BMJ Supportive & Palliative Care. Heart surgery is a major procedure, necessitating the separation of the breastbone (sternum) as well as mechanical breathing support, both of which are associated with a high risk of severe pain, stress, and sleeplessness, note the researchers. Effective pain relief allows patients to recover more quickly and may reduce the risk of postoperative complications, ...

SEATTLE, Wash. August 3, 2023 – An analysis of 19 causes of death in the United States revealed persistent disparities and a familiar pattern across five racial-ethnic groups and 3,110 counties from 2000 to 2019. That’s according to the most comprehensive peer-reviewed research published today in The Lancet.   The mortality rates among American Indian or Alaska Native (AIAN) and Black populations were substantially higher than among White populations nationally and in most counties. For example, mortality was higher among the AIAN population than the White population in nearly all counties for skin and ...

As little as 25 minutes a day of slow walking seems to be enough to counter the detrimental physical effects of bedrest on older hospital patients, finds a pooled data analysis of the available evidence, published online in the British Journal of Sports Medicine. And for optimal improvements in physical function, around 50 mins/day of slow walking or  around 40 mins of combined physical activities, such as 20 mins of resistance bands with around 20 mins of aerobic activity, are the most effective, the analysis indicates. But there may be a threshold effect, with no clear benefit for ‘doses’ of more than 90 mins/day ...

An international team of scientists have discovered an unusual Jupiter-sized planet orbiting a low-mass star called TOI-4860, located in the Corvus constellation. The newly discovered gas giant, named TOI-4860 b, is an unusual planet for two reasons: stars of such low mass are not expected to host planets like Jupiter, and the planet appears to be particularly enriched by heavy elements. The study, led by University of Birmingham astronomers, is published today (Friday 4th August) in a letter published within the Monthly Notices of the Royal Astronomical Society. The planet was initially identified using NASA’s Transiting Exoplanet ...
