Race, ethnicity–adjusted age recommendation for initiating breast cancer screening

JAMA Network Open

2023-04-19
(Press-News.org) About The Study: This study of 415,000 breast cancer deaths in female patients in the U.S. from 2011 to 2020 provides evidence-based race-adapted starting ages for breast cancer screening. The findings suggest that health policy makers and clinicians could consider an alternative, race and ethnicity–adapted approach in which Black female patients start screening earlier. 

Authors: Mahdi Fallah, M.D., Ph.D., of the German Cancer Research Center in Heidelberg, Germany, and Tianhui Chen, M.D., Ph.D., of the Zhejiang Cancer Hospital in Hangzhou, China, are the corresponding authors.

Cognitive function in people with familial risk of depression

2023-04-19
About The Study: Depression in prior generations was associated with lower cognitive performance in offspring, whether assessed by family history or genetic data. There are opportunities to generate hypotheses about how this arises through genetic and environmental determinants, moderators of brain development and brain aging, and potentially modifiable social and lifestyle factors across the life span. Authors: Breda Cullen, Ph.D., of the University of Glasgow in Glasgow, United Kingdom, is the corresponding author. To ...

Nature publication on loops, flags and tension in DNA

Nature publication on loops, flags and tension in DNA
2023-04-19
1 Cohesin loops DNA It has been known for more than a century that the long DNA strands in cell nuclei are neatly folded into the characteristic shape of chromosomes, resembling bottlebrushes , in preparation for cell division. And also between divisions, chromosomes are organised into loops that are important for regulating the processing genetic information. In 2018, Dekker and his group were the first to visualise how SMC protein complexes such as condensin and cohesin extrude loops in DNA. #2 CTCF flags have a direction and determine where a ...

Nature-study reveals new mechanism for DNA folding

Nature-study reveals new mechanism for DNA folding
2023-04-19
A hitherto unknown mechanism for DNA folding is described in a study in Nature published by researchers from Karolinska Institutet and the Max Planck Institute for Biophysics. Their findings provide new insights into chromosomal processes that are vital to both normal development and to prevent disease. The DNA in our cells is organised into chromosomes, which are highly dynamic structures that are altered when genes are transcribed, when DNA damage is repaired or when chromosomes are compacte in preparation for cell division. These processes are affected by so called SMC protein complexes (SMC, Structural Maintenance of Chromosomes), which by mediating chromosomal interactions ...

New findings pave the way for stable organic solar cells that may enable cheap and renewable electricity generation

New findings pave the way for stable organic solar cells that may enable cheap and renewable electricity generation
2023-04-19
Due to the recent improvements in the efficiency with which solar cells made from organic (carbon-based) semiconductors can convert sunlight into electricity, improving the long-term stability of these photovoltaic devices is becoming an increasingly important topic.  Real-world applications of the technology demand that the efficiency of the photovoltaic device be maintained for many years. To address this key problem, researchers have studied the degradation mechanisms for the two components used in the light-absorbing layer of organic solar cells: the ‘electron donor’ and ‘electron ...

Perspective on oligomeric products from lignin depolymerization: their generation, identification, and further valorization

Perspective on oligomeric products from lignin depolymerization: their generation, identification, and further valorization
2023-04-19
Lignin depolymerization is playing a pivotal role in transforming the second most abundant biopolymers in nature into many valuable chemicals/fuels. This route could directly replace their petrol-based equivalents and therefore a great pathway to fight climate change and contribute to future sustainability. Interpretation of the reaction pathways is always desired to gain an insightful mechanic view in understanding the depolymerization chemistry and also paving new paths for lignin valorization at the industrial scale. However, such interpretation heavily relies on the state-of-art analytical capability since ...

UVA launches ambitious effort to reduce health disparities

UVA launches ambitious effort to reduce health disparities
2023-04-19
The University of Virginia School of Medicine has launched a new Center for Health Equity and Precision Public Health to improve the health and well-being of rural residents, the economically challenged and minority groups across Virginia and beyond.  The center will bring to bear expertise from across UVA to tackle many of today’s greatest public health issues. The goal: reduce health disparities and promote health equity to help people live longer, healthier lives.  “The pandemic has really taught us that, one, our public health infrastructure is not nearly as strong as it should be. And, two, we can't ...

Wonder drug-capsule may one day replace insulin injection for diabetics

Wonder drug-capsule may one day replace insulin injection for diabetics
2023-04-19
Scientists in Melbourne have designed a new type of oral capsule that could mean pain-free delivery of insulin and other protein drugs. Co-lead researcher Professor Charlotte Conn, a biophysical chemist from RMIT University, said protein drugs had proven challenging to deliver orally as the drugs degrade very quickly in the stomach – until now. “These types of drugs are typically administered with an injection – thousands of diabetics in Australia need insulin injections up to several times a day, which can be unpleasant for the patient and results in high healthcare costs,” said Conn, from RMIT’s School of Science. She said the new technology could also be ...

Nebraska-led study first to define anxiety spiraling from national election

Nebraska-led study first to define anxiety spiraling from national election
2023-04-19
Researchers are beginning to better understand the toll of polarized politics on mental and physical health, and a new study suggests that Americans’ political anxiety crescendos before a major election. Led by University of Nebraska–Lincoln political scientist Kevin Smith, with Aaron Weinschenk of the University of Wisconsin–Green Bay and Costas Panagopoulos of Northeastern University, the study is the first to examine anxiety tethered to a specific political event — the 2020 presidential election, touted by both sides as the ...
